【摘要】：本文提出一種采用雙分層水箱的太陽能噴射制冷循環(huán),分層水箱熱分層顯著,頗具可用能儲(chǔ)存優(yōu)勢,結(jié)合大小水箱各自的優(yōu)勢彌補(bǔ)因太陽日輻射量波動(dòng)而導(dǎo)致太陽能利用率不高、太陽能驅(qū)動(dòng)的噴射制冷效率較低等問題。采用逐時(shí)冷負(fù)荷分析法分析了雙分層水箱太陽能噴射制冷系統(tǒng)特性,結(jié)果表明:該制冷循環(huán)高品位能耗約為普通機(jī)械壓縮制冷循環(huán)的1/5,較傳統(tǒng)水箱太陽能噴射制冷循環(huán)全天工作時(shí)間約多4 h,日產(chǎn)冷量提高36.8%,且分層水箱噴射制冷系統(tǒng)的逐時(shí)制冷量與辦公室逐時(shí)冷負(fù)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.
