摘要
在青岛地区建立一套太阳能热泵实验系统,该系统可以完成冬季太阳能热泵供暖(启动热泵)和非采暖季太阳能直接供热水实验.进行了太阳能直接供应生活热水工况的实验研究,测得在春、夏、秋测试时间内,集热器的平均得热量:春季为2.82 kWh/m2,夏季为2.73 kWh/m2,秋季为3.13 kWh/m2.如果按水的温差为28℃,则春、夏、秋三季日产热水量为75.3 L/m2.d,56.5 L/m2.d和81.2 L/m2.d(按晴天计算).
A solar assisted heat pump system for heating in winter and supplying hot water in other season was set up in Qingdao. The, experimental study was conducted for solar hot water supply. The average heat output is respectively 2.82kWh/m^2 in spring,2.73kWh/m^2 in summer and 3.13kWh/m^2 in autumn. The hot water output is respectively 75.3L/m^2·d in spring, 56.5L/m^2· d in summer and 81.2L/m^2 ·d in autumn if the temperature difference is 28℃.
