Abstract

PURPOSE: For reducing the flowing sound of refrigerant and the internal pressure loss of pipe, to feed a portion of the refrigerant having passed through a reducing expander to the suction side of a compressor after the heat exchange thereof with the refrigerant before said reducing expander.
CONSTITUTION: The high-temperature, high-pressure gas refrigerant discharge from a compressor 2 is led to a condenser 3 and condensed into high-temperature, high- pressure state. Thus-obtained refrigerant is led to a reducing expander 4 through a heat exchanger 6 to become low-temperature, low-pressure state. Thus-obtained refrigerant contains 20W30% of unrequired gas refrigerant not contributing to cooling. Therefore, said gas refrigerant is led to said heat exchanger 6 through a bypass pipe 7, evaporates through the heat exchange thereof with said high-temperature, high-pressure refrigerant, and is led to the suction side of said compressor 2 through a second bypass pipe 8. In the meanwhile, the remainder portion of said refrigerant present at said reducing expander 4 is introduced into said evaporator 5 and returned to said compressor 2 after performing cooling as known.
