Safety devices
Compressors integrate safety functions such as:
- Low Suction and High Discharge Pressure
- SurgeHigh Motor Temperature
-
Low Motor Current
-
Starter Fault
-
Sensor Fault
-
Evaporator
– Condenser Water Flow Loss
Notes (1) Minimu and maximum capacity, unit power input EER are based on the following nominal conditions: evaporator water temperature 12/7°C;
condenser water temperature 30/35°C, unit at full load operation.
Notes (2) For two compressors unit minimum capacity is with one compressor only runnin
Notes (3) ESEER and IPLV are calculated with 100% load equal to maximum capacity
Notes (4) Nominal flow rate an pressure drop are at maximum capacity with two passes heat exchangers
Notes (5) The values are according to ISO 3744 and are referred to: evaporator water temperature 12/7°C; condenser water temperature 30/35°C, unit at full
load operation at maximum capacity
