摘要
提出一种新型的集热/蓄能/蒸发一体化太阳能热泵热水器系统,并分析该系统的工作原理,搭建此系统的实验测试装置。在实验测试的基础上,定义一体化太阳能热泵热水器系统的得热效率并与直膨式太阳能热泵系统进行比较;分析系统不同工况下的性能系数。实验研究表明:集热/蓄能/蒸发一体化太阳能热泵热水器系统集热/蓄能/蒸发器的得热效率高于直膨式太阳能热泵热水器的得热效率;集热/蓄能/蒸发一体化太阳能热泵热水器系统的性能系数COP平均值为7.56。
A new solar heat pump water heater integrated with collector, storage and evaporation was presented. The new system＇ s working principle was analyzed and the experimental device was set up. Based on the experimen- tal text, the solar thermal efficiency of the integrated solar heat pump system was defined and it was compared with that of the direct expansion solar assisted heat pump system. Moreover, the COP of this integrated solar heat pump water heater system was analyzed. The results indicated that the solar thermal efficiency of this new system is more efficient than that of the direct expansion solar assisted heat pump water heater. In the experiment, the average COP of this new solar heat pump water heater was 7.56.
