Abstract

Refrigerant installation of compressor with throttle device mounted between condenser and evaporator, and electric heating resistor temporarily connectable and associated with said device, a chamber being mounted in front of at least a part of the throttle device and the electric heating resistance being a resistance ptc, that is, a resistance of positive temperature coefficient, arranged in the chamber, that in case of exceeding a temperature zone between the evaporation temperature of the refrigerating agent, associated with the pressure in the chamber, and the carbonization temperature of the refrigerant oil, passes from a resistance value under a high one, characterized in that the part of the throttle device that is mounted next to the chamber is formed by a short throttle element in axial direction, such as a fixed nozzle or a diaphragm.
