ABSTRACT OF THE DISCLOSURE
The present invention relates to a compressor refrigera-
tion 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.
