Lumina 38 Basic principles climate management

3. Basic principles climate management

This chapter explains the basic principles and the terminology used for the Lumina 38 climate computer. The control computer is suitable to control temperature, relative humidity (RH) and fresh air in animal houses through ventilating, heating and cooling.

As the control computer is suitable for use in a wide variety of climatic conditions, many parts of this chapter may not be relevant for all users.

3.1 Aims

Climate management has one central aim: controlling the temperature, relative humidity and the CO

2

or NH

3 concentrations during the animals’ lifecycle. This leads to the following aims:

•

The lifecycle of the animals is leading for climate management. Young, growing animals need, for example, more heat and less fresh air than older animals. For this reason the ambient temperature during the animal’s lifecycle should gradually decrease, while ventilation should increase.

•

Even temperature and air distribution in the house.

•

Continuous monitoring of the house climate.

•

Taking outside influences into account, such as outside temperature, wind and relative humidity.

Influences can be used to optimise climate management. Even if this option is not used, the control computer will control the climate satisfactorily.

3.2 M/MT ventilation

The Lumina 38 is extremely suitable for climate control in an MTT-house. The abbreviation MTT stands for

Minimum/Transitional/Tunnel. Using this concept, the control computer gradually increases the ventilation from minimum ventilation to tunnel ventilation.

Tunnel ventilation is (virtually) self-evident in warm climates, such as the Middle East and Asia. However, tunnel ventilation can also be used in temperate or cold climates, to prevent mortality during hot weather. With Fancom’s

MTT-concept the transition from minimum ventilation to tunnel ventilation is gradual. The extra costs of tunnel ventilation (compared to other systems) are slight, thanks to efficient use of the equipment.

Ventilation according to the MTT-concept features the following ventilation phases.

•

Minimum ventilation (M-phase)

•

Transition (M/T-phase)

•

Tunnel ventilation (T-phase)

In each ventilation phase your ventilation system is used in a certain way. This is explained in the sections below. If only minimum or only tunnel ventilation is used, certain of the sections below can be ignored. The ventilation systems shown are some examples of the possibilities.

3.2.1 Minimum ventilation (M-phase)

In this phase the control computer uses fans combined with air inlets. The tunnel inlets are closed. In places without air inlets, the natural curtain together with the tunnel inlets can provide minimum ventilation.

Ridge ventilation is used in this example. The air inlets distribute the fresh air well through the house. Thanks to the minimum exhaust, no energy is wasted. One of the fan types below can be used:

•

Linear controllable fans

The control computer controls ventilation using a percentage, for example from 30% to 100%. The control computer can increase ventilation precisely up to the required level.

•

Modulating fans and on/off fans

The other fans are on/off fans. The control computer can use these as modulating fans. The control computer activates/deactivates the fans using a fixed pattern. This supplies fresh air in short repeated periods.

Example: Modulating ventilation

The control computer uses four fans for modulating ventilation. The ventilation level is 70%. This means that the fans are on for 70% of the time and off for the remaining time.

At a ventilation level of 100%, the fans run the entire time.

4

Lumina 38 Basic principles climate management

3.2.2 Transition zone minimum ventilation – tunnel ventilation (MT-phase)

In this phase the control computer uses fans combined with air inlets and tunnel inlets.

In this phase the control computer uses the following fan types:

•

Linear controllable or modulating fans (like in the M-phase)

•

On/off fans

In this example the on/off fans are mounted in the rear wall of the house. On/off fans are either on or off at a certain ventilation level — there is no intermediate position.

3.2.3 Mechanical ventilation

With mechanical ventilation the control computer can control the house temperature using fans. The control computer can control various numbers and types of fans. Which of the fans will be used to achieve a certain ventilation demand has been set in the combi-table.

With mechanical ventilation use is made of:

•

Controllable fans

The control computer can control the controllable fans at a certain percentage. The control computer controls the fans from, for example, 30% to 100%. This enables the control computer to increase ventilation precisely up to the required level.

As well as the standard controllable fans, extra controllable fans can also be controlled. All controllable fans are always controlled at the same percentage.

•

Extra fans (on/off relay)

Extra fans can only be switched on or off. They are usually used when the controllable fans are running at maximum or in combination with controllable fans to achieve a gradual increase in ventilation.

Ventilation control

The control computer uses control values to control the climate management system. It continually adjusts these control values, because the control computer constantly monitors the climatic conditions in and around the house.

The user can change the control values.

The following applies for ventilation:

•

The ventilation will never become lower than the set minimum ventilation.

This means the house is always ventilated enough to supply the animals with sufficient fresh air. The control

computer calculates the minimum ventilation using the curve («Curves» page 64).

•

If the house becomes too warm, the control computer will increase the ventilation in order to lower the house temperature.

The control computer gradually increases the ventilation. However, ventilation will never exceed the set

maximum ventilation.

Figure 1: Ventilation graph

5

Lumina 38 Basic principles climate management

The ventilation graph has the following zones:

•

Heating zone

The heating is on and there is minimum ventilation.

•

Neutral zone

The heating is off and there is minimum ventilation.

This neutral zone avoids the heating or additional ventilation activating due to slight temperature fluctuations.

This saves energy. The

Control value heating

,

Setpoint house temperature

and

Start temperature ventilation

are user settings. These can be used to set the neutral zone.

•

Ventilation zone

The control computer gradually increases ventilation from minimum (for example 20%) to maximum (for example 100%).

In the controllable ventilation range the controllable fans are used. In the extra ventilation range the extra fans are used.

Combi-table

The control computer determines how the fans and air inlets are used based on the combi-table. The combi-table has been set by your installer for your house.

3.3 Heating

The setpoint house temperature is the foundation for both heating and extra ventilation. There is a margin above and below the setpoint house temperature: the neutral zone. In the neutral zone there is minimum ventilation and no heating. Setting the neutral zone correctly saves on energy costs.

Figure 2: Ventilation graph. Setpoint house is 21°C, the control value heating is 20.5°C.

The control computer uses a hysteresis when controlling the heating. This prevents the heating being activated/deactivated with slight temperature fluctuations. The hysteresis in the figure is 1°C.

The control computer activates/deactivates the heating as follows:

•

Heating ON: if the house temperature falls below the hysteresis (in the example, 19.5°C).

•

Heating OFF: if the house temperature rises above the control value heating (in the example 20.5°C).

Several heating units

The house (or section) can be divided into zones which can be heated separately. Per zone, temperature sensors can be linked to the heating for that particular zone.

Heaters can also be linked together. The linked heater then shadows, possibly using a certain offset, the heating values of the first heater. The feature can also be used for low/high control. The control computer will activate the heaters one by one.

Separate setpoint heating

The previous example assumed one setpoint house temperature for ventilation and heating. The heating can also be given a separate setpoint, the so-called ‘extra temperature’. The extra temperature can be entered in the curve.

This may be necessary to control floor heating. In this case, the sensor measures a different temperature to the actual house temperature. Other setpoints must be set in this case.

6

Lumina 38 Basic principles climate management

3.4 Cooling

The control computer has one cooling control with separately assigned temperature sensors. The control computer can activate the cooling at high temperatures.

The control computer automatically activates the cooling based on the

control value cooling

. The user can enter the control value. The control computer can use a hysteresis. This prevents the cooling being activated/deactivated because of slight temperature fluctuations:

•

Cooling ON: if the temperature in the house rises above the hysteresis.

•

Cooling OFF: if the temperature in the house drops below the setpoint cooling.

The control computer can control the following types of cooling:

•

Dry cooling, for example, a heat exchanger or air conditioner.

The temperature of the air inlet is lowered. The absolute humidity of the air will not increase. As the temperature falls, the Relative Humidity (RH) will be increased.

•

Evaporative cooling, for example using cooling pads in the inlets.

The temperature is lowered by the effect of the water evaporating. Both absolute humidity and RH increase.

Water is sprayed at regular intervals. The water supply is controlled modulating, so the supply is on or off at regular intervals. Depending on the house temperature, the on-off time is determined based on the bandwidth set by the user, the maximum on-time and the period within which cooling may be active. When the house temperature drops below the setpoint cooling temperature, the cooling turns off.

Linking cooling control to ventilation

With a standard cooling control in a house with basic ventilation the cooling control is often linked to

STV.+BW

(

Start temp. ventilation + bandwidth

). The control computer activates the cooling as soon as the ventilation is at maximum.

Start temperature ventilation

depends on

Setpoint section temperature

, even if this is linked to the curve.

Separate setpoint for cooling

The cooling can also be given a separate setpoint, the so-called ‘extra temperature’. The extra temperature must be entered in the curve. The extra temperature is used if the control value of the cooling differs greatly from the setpoint house temperature.

3.5 Relative humidity

The control computer can influence the relative humidity (RH) in the house. The maximum RH can be entered in the curve. The control computer determines the

RH control value

based on the curve.

The control computer can control the humidity as follows:

•

RH is too low: The control computer can activate extra humidity. For example, water nozzles.

•

RH is too high: The control computer can activate extra heating or ventilation. Warmer air can absorb more moisture. Extra ventilation can be used to extract more moisture from the air.

3.6 HumiTemp and Windchill (N.E.T.)

For the best results animals have to stay in their comfort zone. This comfort zone depends on a number of factors including temperature, relative humidity and airspeed. HumiTemp can correct the temperature based on the actual relative humidity in combination with the actual temperature. The effect of the HumiTemp can be controlled by the following factors:

•

•

Age

Minimum correction

•

Maximum correction

7

Lumina 38 Basic principles climate management

When HumiTemp is activated the control works on the HumiTemp instead of the average house temperature.

On the left side of the graph the RH is below the setpoint RH. Therefore HumiTemp is significantly under the measured house temperature. On the right side of the graph the RH is measured the setpoint RH. Therefore

HumiTemp is significantly above the measured house temperature.

Windchill (N.E.T.)

The Net Effective Temperature, also called windchill, is the temperature that the animals experience. It is a combination of temperature, humidity and airspeed in the house. N.E.T. appears on the screen as an additional icon

(little chicken + thermometer )

3.7 Clock

The control computer has a number of clocks used to activate/deactivate equipment.

3.7.1 Water and feed

The supply of water and feed can be controlled based on time or amount. The water or feed clock activates a valve in the supply pipe. The water and feed supply can be controlled as follows:

•

•

•

Based on time using the water and feed clock.

Based on the supplied amount using a registration unit.

Based on the set curve.

Measuring the amount of water is only possible if a water meter is used. This must be indicated at

Water registration

in the system settings. The registration of amounts is set at registration in the system settings.

How does the control computer control the watering process?

The supply to the drinking nipple or drinking cups can be opened or closed using a valve. If you want to register amounts, you require a water meter. It is possible to use 11 water meters (1 central meter and 10 meters for each water line). The measurements are only suitable for monitoring.

The watering process is controlled by the Lumina 38 as follows:

8

Lumina 38

1. The water clock indicates that watering must start.

Basic principles climate management

2. The valve is opened. The watering system must be completely filled first. For this reason no maximum flow alarm will be given during a set wait time.

After this wait time, a check can be made to see the water consumption is too low (blockage) or too high

(leakage). This is done by repeatedly checking if too little water has flowed through the system. A check is also made to see if too much water has been consumed during a period.

How does the control computer control the feed process?

The Lumina 38 uses a so-called «full system». This means that after the feeding process has stopped, the computer ensures the hoppers are always filled. When feeding starts, a large amount of feed can be supplied within a short time. As the hoppers are completely filled again after the feeding cycle, the control computer knows how much feed was used in each feeding cycle.

The hoppers are filled via the overflow principle. Feed falls into the hoppers via a chute. When the first hopper is full, the feed overflows into the next one etc. The feed line auger runs synchronously to the feed supply from the silo. If the feed supply stops, the feed line stops too.

The feed process is controlled by the Lumina 38 as follows:

1. The feed clock indicates that feeding must start.

2. The dosing out auger transports the feed to the hoppers. When there is a feed demand (feed sensor uncovered), the dosing out auger will activate. The feed is transported to the hoppers.

3. The hoppers are filled successively according to the overflow principle. When the last hopper is full (detected by the demand sensor), the control computer stops supplying feed.

4. From the hoppers the feed line augers transport feed to the feed pans. The feed pans are also filled according to the overflow principle.

9

Lumina 38 Basic principles climate management

Program

There are two ways to control the process. We refer to this as the program:

•

REGISTRATION

Ad libitum. The amount is determined by the animals’ behavior. The clock determines how long feed or water is supplied. Within each cycle, the animals can consume as much feed or water as they like. The demand sensor in the final hopper indicates if dosing out is possible.

The curve has no influence on the amount of feed or water given. The curve only indicates the theoretical amount required and is used as a reference. If the amount given differs too greatly from the amount in the curve, an alarm can be given.

•

DOSING

Limited. The amount is determined based on the curve. The computer calculates the required amount per day using the curve. The day amount is divided over the number of cycles.

When the required amount in a cycle has been dosed out (within the time the cycle lasts), dosing out will stop.

If the animals consume less feed or water during the cycle than the calculated required amount, the supplied amount will be registered. The time of the cycle must be long enough to allow the required amount to be dosed out within the set time. If the required amount is not dosed out within the cycle, an alarm can be given.

If you want to adjust the amounts automatically, then you have to enter this data beforehand in a curve. If you assign the right curve, the control computer will automatically control how feed or water is given. These settings can be differed from, if for example more or less feed or water must be given.

3.7.2 Light

Several light clocks are available per house. These clocks can be switched inter-dependently and independently.

Lighting can be activated and deactivated and controllable lighting can also be controlled. Controllable lighting can be controlled in percentages. This allows natural light patterns to be imitated. The lighting in the house can also be made dependent on the measured light intensity (using a light sensor). This allows the light intensity to take the incidence of natural day light into account.

Light schemes

The switching pattern for the light clocks, including the high and low level, can be set in a curve.

A light scheme is basically the same as a fixed setting for the time clock, with on and off times and a light intensity.

Several light schemes can be set. These schemes can be assigned to certain days in the animals’ lifecycle. From that day the light scheme will be applied.

The light scheme can be adjusted here per day number. The example below uses three light schemes.

Example: light schemes

Normal light clock setting:

ON – OFF

06:00 – 12:00

16:00 – 20:00

Increase time: 00:10:00

High level: 90%

Decrease time: 00:30:00

Low level: 20%

Two schemes are defined:

Scheme 1: Curve day 7

ON – OFF

06:00 – 13:00

16:00 – 21:00

Increase time: 00:10:00

High level: 75%

Decrease time: 01:00:00

Low level: 10%

10

Lumina 38 Basic principles climate management

Scheme 2:

ON – OFF

06:00 – 21:30

Curve day 12

Increase time: 00:00:00

High level: 70%

Decrease time: 01:30:00

Low level: 0%

According to these settings the light in the house will follow the pattern set at the normal light clock settings until day 6. From day 7 light scheme 1 will be applied. From day 12 light scheme 2 will be applied.

3.8 Registration

The control computer has a number of registration inputs to which a signal pulse or contact can be connected.

These can be used to register («Registration» page 63) amounts (for example, water consumption).

3.9 Climate based on curves

The optimal house climate is a combination of the correct temperature, ventilation and relative humidity:

•

Temperature. As animals grow, their need for heat decreases.

•

Ventilation. As animals grow, their need for ventilation increases. Fancom uses the term ‘minimum ventilation’ for this. Extra ventilation is required on warm days.

•

Relative humidity (RH). As animals grow, the required relative humidity can also change.

There are two ways to control the section climate during the animals’ lifecycle:

•

Manually

Enter the control values manually. This means the computer will use the same control values each day until they are changed. This approach can be used with constant climatic conditions.

•

Automatically, based on the curve

The animals grow, which means the climate has to be regularly adjusted. The changing temperature, ventilation and RH can be set in a table adjusted to suit the weight and needs of the animals during their life cycle. This table is called the ‘curve’.

See: Curve («Curves» page 64).

Examples of curves with the changing temperature, RH and ventilation during the animals’ lifecycle:

Changing data

•

Setpoint house

: The temperature graph is linked to the

Setpoint house

(control value). If this value is increased, for example, the control computer will also increase the linked value.

•

Bandwidth

: The bandwidth is the set number of degrees from start temperature ventilation, within which ventilation goes from the minimum to the maximum position.

•

Offset tunnel position

: This offset prevents the control computer activating the tunnel ventilation if there is just a slight rise in the house temperature. If the house temperature drops below the lowest tunnel ventilation position the

Offset tunnel position

applies.

Heating or cooling not linked to

Setpoint house

The values in the temperature graph are general values. However, the method of control can also be set per heating or cooling unit. For example, the floor heating can be controlled using a separate

Extra temperature

, as the temperature sensor is placed in the water circuit. The

Extra temperature

can be set separately in the curve.

4.3 Ventilation

The control computer shows general information about ventilation in the overview screen ( ).

The control computer always shows latest data, including all offsets and influences. The ventilation settings concern:

Fan positions.

The positions of air inlets and extra inlets.

The pressure in the house.

4.3.1 Ventilation graph

The readout of the ventilation level and the air quantity is shown in the ventilation graph. The control computer uses the ventilation level to determine the positions of the fans, air inlets and extra inlets, based on the combi-table. If an under pressure control is also used, the air inlet positions may be adjusted to achieve the required under pressure.

The ventilation level depends on the house temperature. The control computer shows the ventilation level either as percentage (0 – 100%) or tunnel phase (T1, T2 etc.).

The control computer can activate tunnel ventilation, if the house temperature is higher than the upper limit of the bandwidth (increased with the offset bandwidth). This is only possible if the maximum ventilation level is set to at least T1. If the maximum ventilation level is set to 100% or lower, the control computer will not activate tunnel ventilation.

7. Advanced climate settings

This chapter covers the advanced settings in the control computer.

7.1 Requesting and setting control settings

After a menu option for specific data, the control computer displays a number of tab pages with codes. Certain tab pages concern a control, others an influence.

This section explains what comprises a control. It’s better to read a screen concerning a control from top to bottom.

This shows you exactly how the computer has calculated the actual control value.

The computer usually shows the following data:

•

Norm value or setpoint.

The setpoint is the value usually calculated by the computer based on the curve or setting in the combi-table.

•

Offset or Curve correction

The offset is the difference between the setpoint and the required control value. If the control value is changed, the computer will automatically determine the offset. The control computer adds the offset to the setpoint.

An offset is retained. You can reset the offset to zero in edit mode. If a curve is used, the offset will be reset if the day number is set to 0.

•

Total of all influences. See also: Requesting Management & Monitoring overviews page 31.

For example, temperature, RH, wind and pressure influences.

This total is also added to the setpoint or subtracted.

•

Current value or control value.

The computer uses the control value to control the climate management system.

Select the required control value for the section climate based on your own judgement.

A value with an offset is shown bold in the overview screens.

7.2 Manual adjustment of the current values

You may sometimes want to manually adjust the values calculated by the computer. You simply have to adjust the control values in the settings. The computer calculates the difference (offset) compared to the setpoint.

The following applies after the settings have been adjusted manually:

•

•

•

•

•

The setpoint remains unchanged.

The computer controls using the manually set values (setpoint + offset).

The difference is retained.

A value with an offset is shown bold in the overview screen.

The offset compared to the curve is shown in the section screen concerned as «curve correction», «offset» or between brackets ().

•

The difference can be reset to 0.0 in edit mode in the settings screen.

•

If you use a curve, the offset will be reset if you set the day number to 0 and when all the animals are delivered.

7.3 Requesting Management & Monitoring overviews

The computer shows certain historical data on tab pages

M&M

. The control computer updates the overviews every day. The most recent data appears at the top.

7.4 Setting influences

The climate controls can be optimised by taking into account the influence of the outside temperature, humidity or wind on the indoor temperature. The influences are usually on a separate tab page

Influences

.

Influences are used to optimise the controls. The computer will control the climate well even if these influences are not used.

Determine per influence if you want to use it or not. The computer will not show the corresponding settings if a certain type of influence is not used. The control computer always shows the calculated, actual influence based on the settings made for the maximum and actually measured values. See Optimising controls using influences (page

50).

7.6 Ventilation settings

The actual ventilation position is determined using the minimum and maximum ventilation settings, the actual section temperature and the bandwidth.

The actual ventilation level cannot be set, but it can be influenced by adjusting the minimum and maximum ventilation level:

•

If, for example, there is not enough fresh air in the section, the

minimum

ventilation level can be increased.

•

If the

maximum

ventilation level is increased, the ventilation can increase more with higher temperatures.

The control computer always shows the latest data, which incorporates all offsets and influences. If the climate is controlled using the curve, the actual minimum ventilation level can never be lower than the calculated setpoint.

8.1.2 Influence high outside temperature on bandwidth ventilation

On a warm summer day ventilation is at maximum. At night or after a thunder storm the outside air often cools down rapidly. This can result in too much cold air entering the house causing the house temperature to drop. Avoid this kind of situations using the

Influence high outside temp.

By setting this influence, the bandwidth will become larger as the temperature rises. When the house temperature drops, the control computer will immediately start controlling on a lower ventilation percentage. When the outside temperature drops below

Start temperature ventilation

, the bandwidth will decrease back to its original value.

Example: Influence high outside temperature on bandwidth ventilation

Start temp.ventilation

(STV): 20°

Outside temperature (OT): 21°

House temperature (HT): 27°

Set bandwidth

(BW): 6°

The control computer will increase the bandwidth, as long as the house temperature is too high (higher than STV+BW) and the outside temperature is higher than

Start temp. ventilation

. When increased the ventilation always stays maximum.

As long as the outside temperature is too high, the

Calculated bandwidth

will increase and finally reach point P1.

51

Lumina 38 Optimising controls using influences

If the outside temperature falls (greatly) the cold air will also cause the house temperature to drop. The control computer will control using a lower ventilation position after point P1 has been reached. The example shows the ventilation position at a house temperature of 25°C.

As soon as the Outside temperature drops below

, the control computer will decrease the bandwidth again.

8.1.3 Influence low outside temperature on bandwidth ventilation

If it is cold outside, the cooling effect of outside air is greater than if the outside air is warm. To prevent draughts occurring in the house, the bandwidth can be increased with very low outside temperatures. The ventilation level will then increase slower than normally.

6° = 12°.

At an outside temperature of 15° or higher there is no influence. This means a

of 1.0 × 6° = 6°.

8.1.4 Influence low outside temperature on pressure or inlet position

Prevent a cold drop by increasing the air speed through the air inlet. Use one of the following influences:

•

Low outside temperature influence on setpoint pressure

The pressure influence applies when pressure measurement is used and the required pressure has been set to a value higher than 0 Pa.

•

Low outside temperature influence on setpoint air inlets

If there is no pressure measurement a low outside temperature influence can be set to ‘squeeze’ the inlets during cold weather.

from these settings. The new setpoint is calculated as follows:

•

0.8 × 30% = 24%.

•

At an outside temperature of 15°C or higher there is no influence. This means a

Setpoint minimum ventilation

of 1.0 × 30%= 30%.

8.2 Influence temperature difference on air inlets

If more than one air inlet is used and there is a temperature difference in the house, the temperature difference influence can be used.

This influence ensures that the control computer adjusts the air inlets independently in order to minimise the temperature differences. The average position of the air inlets remains the same.

Example: Influence temperature difference on air inlet

Setpoint air inlet

: 30%

Temperature air inlet 1

: 24

°C

Temperature air inlet 2

: 26

°C

Factor influence

: 0.2

The average air inlet temperature is 25°. The difference between the average air temperature and the temperature of air inlet 1and air inlet 2 is 1

°C.

The control computer calculates the following influence:

Factor influence

x Temperature difference x

Setpoint air inlet

= 0.2 x 1 x 30 = 6%.

Temperature air inlet 1 is too low (too cold). The control computer will try to correct this by decreasing the actual output of the air inlet 1 by 6%.

Temperature air inlet 2 is too high (too warm). The control computer will try to correct this by increasing the actual output of air inlet 2 by 6%.

8.3.2 Influence wind

Depending on the wind speed and direction the control computer can influence the controllable ventilation and the air inlets. The working of this influence depends on the wind direction. The control computer uses this to determine if the fans or inlets are on the wind or lee side. The fans and air inlets can be increased and decreased. This description applies to the controllable part, air inlets and extra inlet, but these can be set separately.

Example: Influence wind on air inlets

If wind speed equals or is lower than 3m/s, the

Control value air/extra inlet

.

If the wind speed increases to 12m/s, the control computer will decrease (linearly) the Control

value air/extra inlet for the defined

wind side

to:

0.5 ×30% = 15%.

With wind speeds higher than 12m/s the

Control value air/extra inlet

is 15%.

With wind speeds between 3 and 12m/s the control computer will increase the Control value air/extra

inlet for the defined

Lee side

of the house to: 1.3 ×

30% = 39%.

With wind speeds higher than 12m/s the

For extremely high winds, a maximum control value can be entered. As the wind blows harder, the maximum control value will decrease until it reaches the

8.4 Influences RH

8.4.1 High RH influence on minimum ventilation

If house relative humidity is too high, the control computer can increase minimum ventilation to disperse the excess moisture. This extra minimum ventilation is only possible if the outside air is dry enough. For this reason the control computer determines the absolute humidity content of the inside and outside air. This influence starts to apply when house RH is higher than the

Control value RH

.

The control computer increases the minimum ventilation level by 1%, and checks if the RH decreases. If this is not the case, it increases the minimum ventilation again by 1%. This process continues until the house RH starts to drop.

8.6 Influence pressure on air inlets

If pressure in the house is too low, the control computer will close the air/extra inlet further to raise the pressure in the house. However, if pressure becomes too high, the control computer will open the air/extra inlet further to lower the pressure in the house.

To prevent the inlet opening or closing too far, a limit can be set using two influence factors:

Factor influence (-)

and

Factor influence (+)

.

Example: Influence pressure on air inlet

Measured pressure: 5Pa

Setpoint air inlet / extra inlet

The control computer calculates a

8.8 Influences night correction

Animals usually rest at night and therefore produce less heat and gasses in this period. To maintain a comfortable climate in the house, the minimum ventilation and the setpoint house temperature can be automatically adjusted.

Night correction can influence the minimum ventilation level and the setpoint house temperature depending on the period of the day. The period is determined by a light clock which has been set with the required times and linked to this function. If necessary, the transitional period from day to night and vice versa can also be set using the dim settings of the light clock.

When night correction is active, the control computer adjusts the setpoints of the house temperature and the minimum ventilation accordingly. If the light level of the linked light clock gradually increases or decreases, these setpoints are adjusted accordingly.

8.8.1 Influence night correction on minimum ventilation

Example: Influence night correction on minimum ventilation

Minimum ventilation

Max night influence

is the sum of all influences. The control computer can limit this total influence with a

and a

.

Example: Total influence on air inlet

Setpoint air inlet:

30%

Abs. minimum factor air inlet:

Abs. maximum factor air inlet:

The control computer calculates a minimum limit of 0.5 × 30% = 15% and a maximum limit of 1.5 × 30% =

45%. The control computer calculates the following influences:

•

Influence temperature difference: 5%

•

Influence pressure: 5%

•

Influence wind: 7%

The total influence is 17%. The

Control value air inlet

10.4 Climate management at the start of the lifecycle

10.4.1 Empty settings

The empty settings are the settings that apply on day number 0. On day number 0 the control computer only uses manual settings and not the curve. When the house is empty you probably only use minimum climate settings, for example only the heating.

When all the animals have been delivered, the control computer sets the day number to 0 and controls according to the empty settings. The control computer also sets all offsets to 0.

Entering empty settings:

1.



2. Change the

Day nr

into 0.

The control computer automatically starts controlling according to the old empty settings. These values are saved in the control computer.

3. Return to

Overview

and check the settings. Change as necessary.

See also: Set up animals («Set up flock» page 28).

10.4.2 The correct climate before setting up animals

As soon as the animals have been set up, the climate can be controlled based on the curve («Curves» page 64).

The climate can also be set manually. Control is not (yet) curve based.

This process can also be started earlier, for example if you want the house to reach a certain temperature before the animals arrive. Do this by:

•

Changing the empty settings

Use day number 0, and adjust the climate settings manually.

•

Activate climate management according to the curve earlier

Enter a negative day number. The control computer will continue to control the climate based on the empty settings. The control computer increases the day number by 1 each day, and skips day number 0. After a few days the control computer reaches day number 1, and will start controlling the climate based on the curve.

Example: Start using curve at midnight

On Thursday enter

Day number

–4. The control computer increases this number by 1 every day at midnight.

Th Fr Sa Su Mo

–4 –3 –2 –1 1

On Monday at 00:01 the day number has value 1, and the control computer will start controlling the climate based on the curve.

Lumina 38 Alarm

11. Alarm

Request the alarm overview using the alarm key .

There are three tab pages under the alarm key:

1.

Overview

to readout the status.

2.

Settings

to change the alarm settings.

3.

History

to readout the last 20 alarm messages.

Types of alarm

There are two types of alarm:

1.

LOUD

: A loud alarm means a report is shown on the screen and a siren is sounded (if connected). Take action immediately.

2.

SILENT

: With a silent alarm (warning), a report will appear on the screen. This type of alarm is usually less serious. An active process can be stopped, if required.

With both types an alarm message will appear on the screen.

Alarms can be set to

LOUD

or

SILENT

, if required. For nearly all the alarms the user decides the limits outside which alarms must be given.

Alarm statuses

An alarm can have the following statuses:

•

•

ALARM

: Active loud alarm.

WARNING

: Active warning (silent alarm).

•

OFF FOR ..:..

: The user has noticed the alarm; the alarm situation is still present.

•

RECOVERED

: The control computer has automatically recovered the alarm; the alarm situation is no longer present.

Alarm history

As soon as the control computer gives an alarm, the alarm is included in the alarm history. The last 20 alarms with corresponding dates and times can be readout on tab page

History

.

11.1 Dealing with alarms

11.1.1 Dealing with a LOUD alarm

If the alarm system is active and a LOUD alarm occurs, the siren will activate and the LED near the alarm key will flash red.

1. Press once on the alarm key to display the alarm message on the screen. The siren will fall silent at the same time.

2. Then press — within one minute — once more on the alarm key to change the alarm status from

ALARM

to

OFF for 00:15

. This means the alarm has been noticed, but the alarm situation is still present! For the next 15 minutes the computer will not give an alarm again for this situation. A new alarm will only be given if the alarm is briefly within, then outside the alarm limits in this 15 minute period. This time can be adjusted for alarms that require more time to be remedied.

If you do not press the alarm key again within 1 minute, the alarm will reactivate. In this case, start again at step 1 to switch off the alarm.

11.1.2 Dealing with a SILENT alarm

If the alarm system is active and a SILENT alarm occurs, the LED near the alarm key will flash green. When the alarm key has been pressed 1x the alarm screen will appear with the warning. Press alarm key 2x to remove the warning from the screen.

11.1.3 An alarm recovers

With LOUD alarms the alarm situation can be recovered after a while by the user or the control computer.

In the event of a LOUD alarm, the siren will activate first (

Alarm status = ALARM

). If the value responsible for causing the alarm comes within the alarm limits again, the situation is considered recovered and the alarm is over.

The siren automatically deactivates and the alarm status changes into

RECOVERED

. This message remains visible so the user can see what caused the alarm. Press alarm key 2x to remove the message from the screen.

68

Lumina 38 Alarm

11.2 Deactivating the alarm system

The controller alarm can be fully deactivated. Do this e.g. when the house is empty. The controller will give a warning to indicate that the entire alarm system has been deactivated.

If the alarm system is deactivated the control computer will not generate any alarm messages (except system alarms). Never switch the alarm system off during regular operation.

Deactivate the alarm system as follows:

1. Press the alarm key.

2. Change the

Alarm system

status to

OFF

.

The screen shows that the alarm system has been deactivated. A corresponding alarm message will also appear in the

Alarm overview

. The LED near the alarm key will flash green.

Reactivate the alarm system by changing the

Alarm system

to

ACTIVE

. The alarm message stating that the system has been deactivated will be cleared from the

Alarm overview

.

11.3 Testing the alarm system

Test the alarm system as follows:

1. Press the alarm key.

2. Change the

Alarm system

status to

TEST

.

The control computer prepares an alarm message. This appears in the alarm overview and can be cleared by pressing the alarm key. The status of the alarm system will immediately revert to

ACTIVE

.

Fancom advises testing the alarm system weekly for correct functioning. During the test the control computer will give a loud alarm.

11.4 Setting temperature alarms

Certain settings for temperature alarms must be set at:

 tab page

Settings

Setting absolute temperature alarms

The absolute temperature alarm limits must not be exceeded under any circumstance!

Set the absolute temperature alarm limits:

•

Min

: If the house temperature is lower than the set absolute minimum temperature, the control computer will give a minimum temperature alarm.

•

Max

: If the house temperature is higher than the set absolute maximum temperature, the control computer will give a maximum temperature alarm.

Setting temperature difference alarms

A difference alarm is an alarm that ‘shadows’ the climate controller settings. The control computer will give an alarm if the temperature differs too much from the

Setpoint house temperature

.

Set the difference alarm limits:

•

Min

: The control computer gives a minimum temperature difference alarm if the house temperature is below:

Setpoint house

–

Minimum difference

,

•

Max

: The control computer gives a maximum temperature difference alarm if the house temperature is above:

Start temperature ventilation

+

Set Bandwidth

Maximum difference

Temperature sensor faulty

Measurements from connected sensors (except the outside sensor) are reliable as long as measurements are between –99.9

°C and +199.9°C.

Outside these limits, the measurements are unreliable. The control computer will give an alarm. This can mean that the temperature sensor has not been correctly connected or is faulty. The screen displays the value ‘- -‘ at the temperature readout

11.5 Setting pressure alarms

Setting alarm limits

For a pressure alarm set the relative alarm limits in relation to the

Control value pressure.

These limits must not be exceeded under any circumstance!

Set the pressure alarm limits:

•

Min

: The control computer will give a minimum pressure alarm if the measured under pressure is lower than the set

Minimum pressure alarm

. This only applies if the

Control value pressure

has been set to a value above 0

Pa.

•

Max

: The control computer will give a maximum pressure alarm if the measured under pressure is higher than the set

Maximum pressure alarm

. This only applies if the

Control value pressure

has been set to a value above

0 Pa.

Pressure sensor faulty

The control computer will give an alarm if the pressure sensor is incorrectly connected or faulty. The display shows the pressure concerned ‘- -‘.

11.6 Setting RH alarms

Setting alarm limits

The RH alarm limits must not be exceeded under any circumstance!

Set the RH alarm limits:

•

Min

: The control computer will give a minimum RH alarm if the measured RH is lower than the set absolute

Minimum RH alarm

.

•

Max

: The control computer will give a maximum RH alarm if the measured RH is higher than the set relative

Maximum RH alarm

.

This relative limit depends on the Control value RH.

RH sensor faulty

The control computer will give an alarm if the RH sensor is incorrectly connected or faulty. The screen displays a value of 101% at the RH readout.

11.7 CO2 or NH3 Alarm

If CO2 or NH3 measurement is used, the control computer will give an alarm if the set minimum or maximum is exceeded.

11.8 External alarms

The control computer has received an alarm signal from external equipment or intelligent modules.

11.9 Thermo differential

An extreme rise in house temperature can be caused by fire. In such a case, it is important that an alarm is raised quickly. The sensors in the zones can detect sudden rises in temperature. A sensor issues an alarm if:

•

It measures a temperature above 58°C;

•

The maximum temperature increase is exceeded (e.g. an increase of 5°C within 2 minutes).

The control computer monitors to that effect the current house temperature every 30 seconds and compares it with the values of the last 2 minutes.

In addition to the alarm relay, the control computer has an extra relay to connect to the fire alarm installation (FAI).

In case of a fire alarm, this FAI relay then initiates additional actions such as closing fire doors, turning on sprinklers or turning off ventilators.

Автоматическая регулировка параметров приточного и отработанного воздуха и системы отопления с помощью компьютера Lumina 38. 

Мощность системы микроклимата индивидуально подбирается и конфигурируется в зависимости от требований. Множество локальных датчиков создают во всем корпусе не только комфортный и равномерный микроклимат, стимулирующий рост животных, но и дают возможность делить корпус на разные климатические зоны

Lumina 38 может использоваться в птичниках следующих типов:

• Птичники для несушек
• Птичники для молодняка
• Птичники для молодняка кур-несушек
• Бройлерники
• Индюшатники

Lumina 38 отлично подходит для регулирования климата в MTT-помещении. Аббревиатура MTT означает Минимальная / Промежуточная / Туннельная. Используя данную концепцию, компьютер постепенно увеличивает вентиляцию с минимальной до туннельной вентиляции. Использование туннельной вентиляции при теплом климате, таком как на Ближнем Востоке или в Азии. Однако туннельная вентиляция может также использоваться при умеренном или холодном климате для предупреждения падежа во время жаркой погоды. Благодаря МТТ-концепции компании Fancom переход от минимальной к туннельной вентиляции осуществляется постепенно. Дополнительные затраты на туннельную вентиляцию (в сравнении с другими системами) незначительны благодаря эффективному использованию оборудования.
