【摘要】：对一个采用抛物槽式太阳集热器(PTC)驱动的单效溴化锂吸收式制冷系统的制冷和供暖性能进行实验研究。实验结果显示,在考虑管路热损和储热水箱的热损后,夏季系统集热效率在0.24~0.35之间,系统集热功率为9.6~16.6 kW;冬季系统集热效率(采暖效率η_h)在0.42~0.55之间,系统集热功率为10.0~17.1 kW。制冷模式下机组在65~70℃的热水下加热,其制冷系数在0.40~0.60之间,日平均制冷系数为0.45,系统的平均制冷性能系数(COP_(s,av))为0.25;针对该制冷系统存在的一些问题和不足,对其结构设计进行优化分析,为高效太阳能溴化锂吸收式制冷系统的设计提供参考。
