采用效率与损失分析方法,计算比较了电压缩式制冷循环与单效吸收式制冷循环的效率及两种制冷循环在典型工况下各环节的损失。结果表明,当采用合适的发生器温度和热源温度时,两种制冷循环的效率基本相同;电压缩式制冷循环的主要损失发生在压缩机环节,吸收式制冷循环的主要损失发生在吸收器和发生器。讨论了两种制冷循环的改进途径。
Using the efficiency and loss analysis methods, the efficiency of the compression-type refrigeration cycle and the single-effect absorption refrigeration cycle and the loss of the two refrigeration cycles under typical conditions are calculated and compared. The results show that the efficiency of the two refrigeration cycles is basically the same when appropriate generator temperature and heat source temperature are used. The main loss of the compression-type refrigeration cycle occurs at the compressor stage. The main loss of the absorption refrigeration cycle occurs at Absorber and generator. Two ways to improve the refrigeration cycle are discussed.
