摘　　要： 通过分析通讯基站能耗特点及环境要求,建立其环控能耗模拟模型,对典型地区的环控能耗进行模拟分析.以180、240、370 mm砖混墙体和50、75、100 mm彩钢板围护结构为例,分析通讯基站基础室温特性,研究通讯基站在不同环控温度下的空调冷负荷和围护结构的散热量,比较空调系统和空调-热虹吸管联合系统对环控能耗的影响,探讨热虹吸管换热设备的全年节能效果.结果表明,提高环控温度能有效降低空调能耗,从25℃提高到28℃,最高的节能效果达到16%.砖混围护结构的通讯基站中,180 mm厚砖混围护结构的传热系数大,有利于围护基站散热;彩钢板围护结构的通讯基站中,50 mm厚彩钢板的传热系数大,空调能耗低.与空调系统相比,空调-热虹吸管联合系统节能效果明显,最高节能率达到54.5%. Abstract ： Using ambient energy to cool the telecommunication base station in the transitional seasons and winter is an effective measure, which indicates that the potential of energy saving is considerable. Based on the analysis of the energy consumption characteristics and environmental requirements, the energy consumption model is set up, and the simulation analysis is carried out under different conditions in thetypical areas. Taking the brick wall with the thicknesses of 180, 240, and 370 mm and the polystyrene sandwich panel of 50, 75, and 100 mm as an example, the room-base temperature is analyzed, the air conditioning cooling load and the building envelope heat dissipation in the whole year are simulated underdifferent environmental control temperatures, the effect of the air conditioning system coupled with a thermosyphon heat exchanger on the energy consumption of the communication base station is compared with that of the air conditioning system, and the energy saving effect of the thermosyphon heat exchanger is also discussed in different areas. Result shows that higher environmental control temperature （25 -28℃ ） can effectively reduce energy consumption, and the best results can reach 16%. Simulation resuhs show that the envelope material affects the air conditioning cooling load much. For brick material with the envelope of 180 mm in thickness performs better with larger heat transfer coefficient and is propitious todissipate the heat of the base station. For polystyrene sandwich panel material with the envelope of 50 mm in thickness performs better. Compared with the air conditioning system, the air conditioning system coupled with the thermosyphon heat exchanger obviously saves energy with the rate of 54.5%.
