【摘要】：构建了一种多功能直膨式太阳能与空气源复合的热泵系统。在常州的冬季及春季分别对试验样机的运行特性进行研究。试验结果表明:系统在冷暖联供的工况下,即同时产生生活热水和冷冻水,整个过程平均COP为6.0;在冬季,太阳辐射强度为354 W/m~2时,系统制生活热水平均COP为4.32;模拟系统供暖,即将循环水从40℃加热至45℃时,测试结果中最低COP为5.07。在春季,太阳辐射强度为856 W/m~2时,系统制生活热水平均COP为5.78。夏季时,系统同时生产冷热水用于生活热水和供冷的需求;冬季时,由于太阳能的辐射,提高了系统的蒸发温度,热泵的性能因此得到提升。
[Abstract]:A multifunctional direct expansion heat pump system with solar energy and air source was constructed. The operating characteristics of the prototype were studied in winter and spring in Changzhou. The results show that the system produces domestic hot water and chilled water at the same time, the average COP of the whole process is 6.0, and in winter, the solar radiation intensity is 354W / m ~ 2, the average COP of the system is 4.32. When the circulating water is heated from 40 鈩，
