摘要
设计了以非同态双热源复合换热器为核心技术部件的太阳能辅助空气源复合热泵,搭建试验台,按照国家标准规定的单一空气源热泵的3种冬季供热工况(7、2、-7℃)进行实验研究。研究结果表明,该复合热泵冬季低温供热性能明显优于单一空气源热泵,在标准规定的环境温度为-7℃的超低温工况下,复合热泵较单一空气源热泵,制热量提高24%,能效比提高25%以上。
A solar assistant air source heat pump with non-homostasis two heat source composite heat exchanger as the core technology components was designed, and a test stand was built in this paper. Based on the national standard of single air source heat pump in winter heating conditions （7℃, 2℃, -7℃）, the heating performance were studied. The results showed that the composite heat pump heating performance was superior to a single air source heat pump in winter heating conditions. When the air temperature was -7℃, compared with the single air source heat pump, the heating capacity of the solar assistant air source heat pump was raised about 24% and the COP was increased more than 25%.
