Cooling Functions
13.1
Cooling Principles
TRIO supports controlling up to two cooling devices (foggers or cooling pads). The devices can run
separately or together.
The relative humidity directly affects the ability of pigs to cool down, even when the temperature is the
same (heat loss decreases in higher humidity rate causing heat stress). What is important to remember is
that the cooling process adds moisture to the air; therefore it needs to stop when the relative humidity is
too high.
•
To enable limiting cooling according to the humidity, install a humidity sensor.
•
Invalid humidity sensor readings are not taken into consideration.
To avoid causing the animals undo heat stress during periods of high relative humidity, TRIO employs the
following rules:
•
When the temperature reaches the Target Temperature plus the Temperature Difference,
cooling begins and continues until the temperature falls below this point (minus the band).
•
If the humidity level rises above the To Humidity parameter (plus the Humidity Band ), cooling
ceases.
•
Cooling only takes place between the start and finish times.
•
When the minimum OFF time = 0sec, and the temperature reached ON temp + Ramping range
the cooling device operates continuously.
•
While cycling, the minimum OFF time will never be less than 5 seconds.
13.2
Selecting the Cooling Mode
TRIO enables running the cooling device in three different modes:
•
Continuous: When activated, the cooling devices operate continuously.
•
Cycle: When activated, the cooling device operate according to user-defined an on/off cycle.
•
Ramping: Cycle modulation, frequency depends on the error in °C, with respect to the cooling
setting (target).
Go to System > Devices and Sensors and set the relays as cooling (refer to Mapping
Devices, page 50).
1. Go to Climate > Cooling.> Settings.
