摘要

介绍了滚动转子式补气压缩机的设计，并将其在热泵系统中进行了实验研究。分析了不同制热工况下滚动转子式补气压缩机的性能，对比了带闪发器与过冷器的经济器热泵系统、滚动转子式与涡旋式补气压缩机的性能。结果表明：随着室外环境温度的下降，滚动转子式补气压缩机补气后制热量提升比例逐步增大；滚动转子式补气压缩机制热实验中，带闪发器系统的制热量较高；在超低温制热工况下滚动转子式补气压缩机制热量提升18%左右，与涡旋式补气压缩机相比制热量相当，性能略高。

Abstract

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.
