The speed is reduced if the gas cooler outlet temperature is lower than the setpoint. If the minimum speed is
reached, a fan capacity stage is unloaded after a time delay and the speed is increased to the maximum value
at the same time. Finally, the speed controller is disabled via the first fan output S1 of the controller when the
speed has reduced to 0. The speed controller can be disabled with the connected fans by disabling the fan
stage 1 (parameter
ENABL.COND screen 3-1-e) The fan regulation then operates as a step controller with the
steps 2 to n-1.
5.6.8 Gas cooler package with integrated outdoor evaporator in bypass operation
The gas cooler package can be designed as follow in the refrigeration pack system:
• Gas cooler package can be bypassed using a gas cooler bypass (3-way valve)
• An outdoor evaporator (heat pump) can be integrated
The control of the gas cooler bypass and the outdoor evaporator is performed, for example by a GLT 3010.
The pack controller can specifically control the gas cooler fans in these two cases.
Gas cooler bypass operation
If the gas cooler is bypassed using a gas cooler bypass (3-way valve), the fans can be switched off during this
operation. The parameter "
Fan OFF w.Byp. " must be set to YES for this. The information whether the bypass is
activated is signalled by a GLT 3010.
Outdoor evaporator
If the outdoor evaporator is activated, a GLT 3010 can request the activation of the gas cooler fans. The
activation of the fans is performed in a cycle of seconds (the duty times are not taken into account here).
The activation of the gas cooler fans when the outdoor evaporator is activated has higher priority than
the switching off during gas cooler bypass operation.
