Ejector Influence on Performance of Ammonia Absorption Heat Pump System

摘要：

　　A single-effect ammonia absorption-ejection heat pump system is set up.Combined with T-S diagram,performance analysis is presented on the heat pump system with ejector or without ejector.The results show that,with the ejector coefficient equal to 0.5,and the cooling coefficient of performance of the single-effect ammonia absorption heat pump equal to 0.3,0.45 and 1.45 can at least be gained for the heating coefficient of performance and the cooling coefficient of performance respectively.In this paper,relation curve diagram is also presented for the heating coefficient of performance of absorption-ejection heat pump system,the cooling coefficient of performance of single-effect absorption heat pump system and the ejector coefficient.
