Web10 jan. 2024 · The compressor discharge pressure reflects the condensing pressure. The normal value should be 1.4 ~ 1.8MPa, and the protection value setting is recommended not to exceed 2.0MPa. Because the long-term pressure is too high, it will cause the compressor to run too much current and burn the motor easily, causing damage to the … WebAt the evaporator side 3,0-3,5 kW of heat is extracted. The additional heat is generated by the compressor. On the other hand: For a refrigeration system a COP of 4 indicates that 1 kW of electricity is needed for a evaporator to extract 4 kW of heat. Due to this important difference in COP definition, for a heat pump one often speaks of COPh.
