摘要
论述太阳能热泵热水系统的类型及优点,并运用热力学的方法对典型的直膨式系统进行了性能分析,进而计算太阳能热泵系统的经济性,并与几种常用的供热系统进行了比较,结果表明太阳能热泵热水系统在性能系数(COP)和经济性上都优于其他系统,且利用了太阳能,减少了对高位能源的消耗,达到了环保的目的。
The type and advantages of the system for solar assisted heat pump （SAHP） was illustrated. Then the performance for a typical DX-SAHP was analyzed by the means of？thermodynamics, the economics for the SAHP was calculated and compared with other systems. Results indicate that the cop and economics for the SAHP all were superior to the others and the system was good to environment because of utilizing solar energy.
