目前在我国吸收式制冷机组在空调工程中大有发展之趋势。究竟在什么情况下使用吸收式制冷才更为合理呢?这是大家关心的问题。我们知道,选择空调用冷源,一方面应受到环保、卫生、安全、能源利用和运行管理等因素的影响,另一方面考虑的就是最佳经济性问题。本文将用小型锅炉房提供热源的吸收式制冷机与常用的离心式制冷机进行综合的经济性比较。空调用制冷的最佳经济性就是用于其制冷系统的所有费用最低。除主机部分,还应包括与之配套的所有土建以及辅助设备。本文采用年经营费法分析最佳经济性。年经营费应包括 Currently in our country absorption refrigeration unit in the air conditioning project has great development trend. After all, under what circumstances is it more reasonable to use absorption refrigeration? This is a matter of concern. We know that the choice of air-conditioning cold source, on the one hand should be environmental protection, health, safety, energy use and operation and management and other factors, on the other hand is considered the best economic problems. This article will use a small boiler room to provide heat source absorption chiller and commonly used centrifugal chiller for a comprehensive economic comparison. The best economics for cooling air-conditioning are all the lowest costs for its cooling system. In addition to the host part, it should include all the supporting civil construction and auxiliary equipment. This article uses the annual operating fee analysis of the best economy. Annual operating expenses should be included
