太阳能复合能源空调热水系统中热泵系统换热性能的试验研究

Experimental Research on the Thermodynamic Performance of Heat Pump in Solar-assisted Air-conditioner with Water Heater

通过将太阳能热水系统和空调热泵系统结合,设计出太阳能复合能源空调系统。针对该新型系统中的热泵空调热水子系统进行研究,在标准工况下,分别对该系统的3种模式下的换热性能进行试验,数据分析结果表明该系统比传统系统更为高效的,其单独制冷模式下系统最高COP可达5.34,单独热水模式下的静态加热系统COP可达5.78,制冷兼热水模式下系统COP可达4.5。

The research presents a solar-assisted air-conditioner with water heater in which solar water heater and heat pump air-conditioner are combined.The performance of heat pump in the new system is experimentally investigated.The performance of heat pump working at 3 modes under standard condition is measured.The results show that,the COP is 5.34,5.78 and 4.5 at cooling mode,heating mode,and cooling-heating mode,respectively,which indicates that the new system is more effective than traditional systems.
