摘要
介绍了一种直膨式太阳能热泵空调及热水系统。针对春季供热水工况,分别对以太阳能及空气为热源生产生活热水进行了比较,发现以太阳能为热源具有更高的COP值,节能效果更为显著;根据试验数据分析了压缩机工作频率、太阳辐射强度、环境温度等因素对热泵系统性能系数的影响。
A solar energy assisted heat pump system for air conditioning, hot water supply and heating are introduced, the experimental work on spring condition to produce hot water is specially discussed. Experiments were carried on solar energy and air energy respectively, and it is found that solar energy is more attractive to have a high COP and energy saving. The influences of the working frequency of compressor, solar radiation, environmental temperature on the system performances are studied based upon experimental data.
