Research on performance of water vapor compression refrigerator 水蒸汽壓縮式制冷機(jī)性能研究
At the same time , mechanical compression refrigerators consume a big quantity of electric power and indirectly make the pollution problem severe , which bring forward a great challenge to the human ' s sustainable development 隨著人們生活水平的提高,空調(diào)的使用日益廣泛。與此同時(shí),大量使用機(jī)械壓縮制冷系統(tǒng)帶來電能消耗、環(huán)境污染問題也向人類可持續(xù)發(fā)展提出了挑戰(zhàn)。
In this article , a research on how the change of latitude and direction of a solar powered long endurance aircraft effect the received solar power was developed . and on the basis of the car air conditioning , the thermal properties of the single - effect lithium bromide absorption hot - coldwater unit and two - stage lithium bromide absorption hot - coldwater unit applied in car and driven by high temperature cooling fluid of the car engine are advanced and compared . the technique of energetic optimization is employed to investigate the optimal performance of an irreversible hybrid air - conditioning system consisting of a vapor compression refrigerator cascaded with a solar - driver absorption refrigerator 本文對(duì)太陽(yáng)能飛機(jī)的飛行緯度和飛行方向?qū)δ軌颢@得的太陽(yáng)能輻射量的影響進(jìn)行了研究,以及對(duì)應(yīng)用于汽車空調(diào)的兩種溴化鋰制冷機(jī)組,即單效溴化鋰制冷機(jī)組和兩級(jí)溴化鋰制冷機(jī)組進(jìn)行了熱力分析和研究,同時(shí),結(jié)合太陽(yáng)能集熱器作為整個(gè)制冷系統(tǒng)的熱源,對(duì)系統(tǒng)的最優(yōu)綜合性能進(jìn)行了分析和研究。
