| 摘 要： | 采用空冷吸收器、空冷冷凝器实现循环空冷化，是缩小吸收式系统体积、扩大其应用领域的重要途径之一。针对4种空冷双效溴化锂循环，建立集中参数模型，分析比较了不同运行参数（热源温度、室外冷却空气温度、蒸发温度）对4种循环性能的影响情况。结果表明，要实现循环空冷化，必须提高热源温度，同时4种循环相比，溶液在低温溶液热交换器前分流的并联循环热力性能明显低于其他3种循环，不宜空冷化。

| Abstract: | Air-cooled absorber and condenser is one of the most significant methods to reduce the bulk volume of absorption refrigeration system and to extend its range of application.In this paper,lumped parameter model for four double-effect air-cooled lithium bromide absorption refrigeration cycles was developed to analyze effects of varying heat reservoir temperature,cooling air temperature and evaporation temperature on system performance.The simulated result indicated that increased temperature of heat reservoir... |
