Abstract
The delivery side of a refrigerant compressor is connected through an inside heat exchanger to a refrigerant heater, the outlet side of the refrigerant heater being connected with the suction side of the compressor. First and second temperature sensors are provided at inlet and outlet sides of the refrigerant heater, respectively for sensing inlet and outlet refrigerant temperatures. A fuel gas supply unit for the refrigerant heater is fitted with a fuel gas control value which is controlled by the temperature differences existing between sensed temperatures by the first and second sensors.
