摘　　要： 在通信基站的能耗中,空调能耗占据了40%左右,为了降低通信基站空调能耗,设计出利用自然冷源的溶液循环式换热机组,以降低空调能耗,并对样机进行了实验测试。结果表明,在实验工况范围内,运行稳定,换热效果良好。换热器的温度效率可达45%,传热系数可达60 W/(m^2·℃)。 The power consumption of air conditioning for a telecommunication base station(TBS) in China occupies almost 40%of the total power consumption.In order to reduce the power consumption,a free cooling unit with working fluid of glycol-water unit was designed for the base station to share the cooling load with the air conditioning,and the prototype also have been tested.The results indicate that the free cooling unit works well with a good heat dissipation performance under the testing conditions.The temperature efficiency of the unit can reach 45%and the heat transfer coefficient reaches 60 W/(m^2·℃)。
