【摘要】 香港地区的淡水资源匮乏,其空调系统一般采用空气冷却型,使得空调能耗占建筑能耗的比例很高。随着香港水务署部分淡水限令的解除,大量用户对空冷式空调系统进行改造研究。本文对香港一空冷式空调系统进行了改进,采用在冷凝器上直接喷水的方式增强其换热效果,并进行了相关性能测试。测试结果表明,改进后的系统比原系统的制冷系数平均高35.9%。更多还原

【Abstract】 Hong Kong’s fresh water resources are scarce,its air-conditioning systems commonly adopt air-cooled air conditioning.Energy consumption of air conditioning system in Hong Kong accounted for a high proportion to building energy consumption.With the Hong Kong Water Supplies Department lift part of the freshwater restriction,a large number of users modify air-cooled air conditioning system.A renovated evaporative air-cooled air-conditioning system was proposed,which used direct water-spraying method to enhance heat-transfer performance and tested the performance of the system.Test results showed,refrigeration coefficient of renovated system was higher than traditional system,averagely 35.9%.更多还原
