【摘要】：本文提出一种采用双分层水箱的太阳能喷射制冷循环,分层水箱热分层显著,颇具可用能储存优势,结合大小水箱各自的优势弥补因太阳日辐射量波动而导致太阳能利用率不高、太阳能驱动的喷射制冷效率较低等问题。采用逐时冷负荷分析法分析了双分层水箱太阳能喷射制冷系统特性,结果表明:该制冷循环高品位能耗约为普通机械压缩制冷循环的1/5,较传统水箱太阳能喷射制冷循环全天工作时间约多4 h,日产冷量提高36.8%,且分层水箱喷射制冷系统的逐时制冷量与办公室逐时冷负荷更吻合。
[Abstract]:In this paper, a solar energy jet refrigeration cycle with double stratified water tank is proposed. The thermal stratification of the stratified water tank is obvious, and it has the advantage of available storage. Combined with the advantages of large and small water tanks the solar energy utilization rate is not high and the efficiency of solar energy driven jet refrigeration is low due to the fluctuation of daily solar radiation. The characteristics of solar ejector refrigeration system with double stratified water tank were analyzed by hourly cooling load analysis. The results show that the high grade energy consumption of the refrigeration cycle is about 1 / 5 of that of the conventional mechanical compression refrigeration cycle, which is about 4 hours longer than that of the traditional solar energy jet refrigeration cycle, and the daily cooling capacity is increased by 36.8%, and the stratified water tank injection refrigeration system is also used. The hourly cooling capacity of the system is more consistent with the hourly cooling load of the office.
