Description
Summary:The paper introduces the design of vapor-injection rotary compressor. Compared to the conventional system, a heat pump system with the vapor-injection rotary compressor has been developed and tested under several conditions. The vapor-injected rotary compressor has been tested with the system of flash tank and internal heat exchanger. The vapor-injected rotary compressor has also been tested compare to the vapor-injected scroll compressor under the same conditions. The results show that when the outdoor temperature decreases, the heating capacity increasing ratio of the vapor-injection rotary compressor is enlarged. The system with flash tank has a better heating capacity compared to the internal heat exchanger. The vapor-injection rotary compressor can effectively increase the heating capacity by 18% for low ambient heating application, and has a comparable performance with scroll compressor.
