【摘要】：對一個采用拋物槽式太陽集熱器(PTC)驅(qū)動的單效溴化鋰吸收式制冷系統(tǒng)的制冷和供暖性能進(jìn)行實驗研究。實驗結(jié)果顯示,在考慮管路熱損和儲熱水箱的熱損后,夏季系統(tǒng)集熱效率在0.24~0.35之間,系統(tǒng)集熱功率為9.6~16.6 kW;冬季系統(tǒng)集熱效率(采暖效率η_h)在0.42~0.55之間,系統(tǒng)集熱功率為10.0~17.1 kW。制冷模式下機(jī)組在65~70℃的熱水下加熱,其制冷系數(shù)在0.40~0.60之間,日平均制冷系數(shù)為0.45,系統(tǒng)的平均制冷性能系數(shù)(COP_(s,av))為0.25;針對該制冷系統(tǒng)存在的一些問題和不足,對其結(jié)構(gòu)設(shè)計進(jìn)行優(yōu)化分析,為高效太陽能溴化鋰吸收式制冷系統(tǒng)的設(shè)計提供參考。
[Abstract]:The refrigeration and heating performance of a single-effect libr absorption refrigeration system driven by parabolic trough solar collector (PTC) was studied experimentally. The experimental results show that after taking into account the heat loss of pipeline and hot water tank, the heat collection efficiency of the system in summer is between 0.24 and 0.35, and the heat collecting power of the system is 9.6 渭 m 16.6 kW;. In winter, the heating efficiency (heating efficiency 畏 _ h) of the system is between 0.42 and 0.55, and the system heat collecting power is 10.0? When the unit is heated at 65 ~ 70 鈩，
