In order to investigate the heating performance of the quasi two-stage compression heat-pump system using R32, an experimental setup was established. The results showed that the discharge temperature of this heat-pump system was 10-20°C lower than that of the single-stage compression system, not exceeding the limit of 130°C, and the heat pump can steadily run for long time under the condensing temperature of 40°C and the evaporating temperature varying from -10 to -5°C.
