I.5.1

Operating limits with the Heat recovery accessory

The chiller and the heat pump can be fitted with the DS partial heat recovery accessory. In that case, operating limits are the same as the unit without
accessory.
If the unit is fitted with the total heat recovery accessory RC100, the winter operating limit (heat pump) remains unchanged, whereas the summer
operating limit is as follows when the recovery is activated:
tue (°C) Evaporator chilled outlet water temperature.
tuc (°C) Hot water temperature leaving the recovery unit
RC100:
The minimum inlet water temperature tuc (°C) admitted is equal to 20°C
DS:
Produced hot water temperature 50÷70°C with admitted water temperature differential 5÷10 K
The minimum inlet water temperature tuc (°C) admitted is equal to 40°C
Note: If the inlet temperature to the recovery unit is lower than the permitted values, it is recommended to use a three-way modulating valve to
guarantee the minimum water temperature required.
