WHE Evaporator Water Pressure Drop
NOTE
The Available pressure head, at the exit of the WHE, is calculated by:
Available Head = Pump Static Pressure - WHE Total Pressure Drop
The external water circuit must be dimensioned accordingly
The WHE Total Pressure Drop is the sum of the evaporator pressure drop, filter pressure drop and flow switch pressure drop
(refer to accessory chapter for information)
WARNING
The minimum evaporating temperature allowed
in cooling mode on the refrigerant side is -2°C
Lower evaporating temperature could cause
freezing in the plate heat exchanger
