On Compression Heat Pump and Its Compressor Design

This paper demonstrates the principle of compression heat pump energy sa- vings, and states the prospects of heat pump application in the area of low tem- perature drying. Also discussed are the working conditions of the key equipment, the compressor in the compression heat pump. The condensing and evaporating temperature ranges under which the heat pump compressor operates are wide. As a consequence, big compression ratios and high temperature of gas discharge will be brought about. Therefore, what are concerned with the heat pump design should be taken into consideration.
