ABSTRACT:
The present invention relates to a compressor refrigeration plant comprising a throttling device between the condenser and evaporator and, associated with the throttling device, an intermittently operable electric heating resistor, a chamber being disposed upstream of at least a part of the throttling device and the electric heating resistor being a PTC resistor which is arranged in the chamber and which, when a temperature range between the evaporating temperature of the refrigerant associated with the pressure in the chamber and the coking temperature of the refrigerant oil is exceeded, goes over from a low to a high resistance.
