Abstract (en)
[origin: EP1837611A2] The heat pump (1) has a defrosting pressure controller (19) arranged between an expansion valve (14) and a refrigerant circuit reversing device (6). The pressure controller is connected with a control unit or a regulator, and is attached to the device. A pressure sensor transmits the signal corresponding to the refrigerant pressure to the control unit or the regulator for terminating the defrosting of the heat pump. A low pressure monitor is arranged in a refrigerant line for safeguarding a compressor (15) on the suction side. An independent claim is also included for a method for operating a heat pump.
