Scroll type of compressor has been used in heat pump & refrigeration system because of its compact size, high efficiency, low vibration and noise level, and excellent running reliability. In the refrigeration cycle the scroll compressor runs smoothly and perfectly, but in the heat pump cycle some troubles appear because its working condition becomes worse. The effect of different factors such as atmospheric condition, electric voltage fluctuation, structure of scroll compressor etc. on running reliability of heat pump system are discussed in this paper. The thermodynamic and aerodynamic behaviors will be emphasized. Some basic design concepts for the running reliability of scroll compressor in the heat pump system are pointed out.
