摘要
提出了一种新型吸收式制冷循环——单效三段(SE/TS)吸收式循环,详细阐述了该循环制冷机组的结构原理、热力循环,并根据热平衡推导出各设备热负荷计算式。通过计算机程序模拟计算,与单效循环机组进行了制冷性能的对比分析。结果表明,在热源温度相同时(80℃以下),采用单效三段式制冷循环时,相比单效循环,其制冷量、热力系数均有所提高,冷却水消耗量下降。
A new type of absorption refrigeration cycle （ Single-Effect/Three-stage Absorption Cycle） has been developed. The refrigeration unit structure principle and thermodynamic cycle was described in detail, and based on the heat balance of the equip- ment are deduced formulas of heating load. By means of computer program simulation, the new cycle has been analysed about re- frigerating performance compared with single-effect circulation. The results show that, in the condition of the same heat source tem- perature（ 〈 80℃C ） , using SE/TS refrigeration cycle, compared with the SE cycle, the refrigeration, coefficient of performance in- creased, cooling water consumption decreased.
