摘要：机房空调能耗约占机房总能耗的40%。在IDC机房节能方案中，使用热管换热器利用自然冷源散热，能够减少空调工作时间，同时可避免室内外空气接触，满足湿度、洁净度的要求。参考北京某IDC机房，搭建试验模型，分析IDC机房内热管换热器和空调各自的散热负荷和能耗特性，研究图护结构的散热特性，比较设定温度和室外温度对空调能耗的影响。结果表明，北京冬季工况下，仅依靠围护结构的散热，无法满足IDC机房的散热需求；图护结构散热量约占IDC机房总散热量的19.5%：空调平均每天耗能3.5~4kWh；使用热管换热器室内外温差不超过20℃，能耗仅为空调能耗的41%，全年节能约40%；与室内设定温度相比，室外气温对空调能耗的影响较大；室外
温度提高1℃，空调能耗平均增加5%～6%。关键词：IDC机房；能耗；热管换热器；自然冷源

Abstract: The energy consumption of the air-conditioning system in the Internet Data Center (IDC) occupies about 4o% of the total energy consumption. The thermosyphon heat exchanger using ambient energy is applied in the IDC to reduce energy consumption. By taking one IDC in Beijing as reference, the testing model is set up to experimentally analyze the heat dissipation characteristics and the energy consumption of thermosyphon heat exchanger and air-conditioning system respectively. The result indicates that the heat dissipation capacity of the building envelope takes about 19. 5% of the total IDC heat load in Beijing winter conditions. The average energy consumption of the air conditioner is 3. 5 kW h ~ 4 kW h per day. And the energy consumption of the thermosyphon heat exchanger takes only 41% of the air conditioner. The annual energy consumption reduces by nearly 4o%. Besides, the effect of the outdoor temperature on the air conditioner energy consumption is remarkable compared with the indoor set temperature. And the air conditioner energy consumption increases by 5% ~ 6% on average when the outdoor temperature raises by 1C.
