太阳能空气源复合多功能热泵系统的试验研究
Experimental Study of Multi-functional Solar-air Source Heat Pump System
摘要
Abstract
A multi-functional direct-expansion type solar-air source heat pump system was developed. An experimental prototype was investigated in summer and winter in Changzhou. Experimental results showed that when domestic hot-water and chilled water are produced at the same time,the average COP(coefficient of performance) of the system is 6. 0;in winter,the average COP is 4. 32 when the average solar radiation intensity is 354 W/m2;when the circulating water was heated from 40 ℃ to 45 ℃ to simu-late the heating condition,the minimum COP in the results is 5. 07. In spring,the average COP is 5. 78 when the solar radiation intensity is 856 W/m2 . In summer,the domestic hot-water and chilled water could be produced simultaneously;in winter,the e-vaporator temperature is raised through solar energy input which,in turn,translates into improvement in the thermal performance of the heat pump.关键词
