自然风冷却技术在深圳市某信息机房应用研究

Applied Natural Cooling in Information Room of an Office Building in Shenzhen

本文对该信息机房的能耗现状进行测试分析,PUE(Power Usage Effectiveness)值为1.7,其中空调系统能耗占比为40%。通过结合深圳市室外气象条件及信息机房安全温、湿度要求,分析了过渡季节采用自然风冷却技术对该信息机房进行降温的可行性,并从节能与经济的角度,进行了技术经济性分析。得出过渡季节在室外气温低于20℃时,自然风冷却技术不仅能够满足该信息机房降温要求,同时降低空调系统的年用电预计达到12000k Wh,改造投资回收期在1.8年以下,社会效益和经济效益显著,在深圳地区具有良好的推广性。

The present situation of energy consume in information room was tested and the value of PUE（Power Usage Effectiveness） was 1.7, in which the proportion of air conditioner was 40%. According to the outside weather conditions and temperature and humidity demands of information room, the feasibility of cooling the information room using natural cooling in transitional seasons was analyzed. The use of natural cooling not only can content temperature and humidity demands, but also decreasing the anural power usage of air conditioner to 12000 k Wh when the outside temperature was lower than 20℃. What＇s more, the capital pay-off time was shorter than 1.8 years. With great social benefits and economic benefits, natural cooling should be widely extended in Shenzhen.
