A quasi two-stage compression of air source heat pump with scroll compressor was introduced. The experimental study and performance analyses of this system were carried out under large-scale variable working conditions. The inputpower, capacity of heating, COP and discharge temperature were gained by the experiment. Besides, based on heating capacity、COP and the working reliability of the system,the optimum compensating vapor intermediate pressure was 1200kPa～1400kPa. The experimental results can provide a valuable reference for the design and application of quasi two-stage compression system.
