摘　　要：建立热管复合式机房空调系统的性能仿真软件,基于DeST气象数据,对哈尔滨、北京、上海、广州4个地区的空调能效进行对比分析,全年的制冷性能系数(EER)变化曲线均呈“U”型,室外平均气温越低,EER越高,节能性越好。与广州地区相比,上海、北京、哈尔滨机房空调系统的年度能效比(AEER)依次提高64%、105%、156%。基于北京地区的气象数据,分析空调系统变室温运行的能效特性,机房设定温度越高,EER越高,节能性越好。室内温度设定为33、30、27℃时的AEER相对24℃的依次提高56%、42%、19%。以节能减排为目标,热管复合式机房空调系统适宜应用在平均气温较低的地区,在满足电子设备可靠性的前提下,可适当提高机房的设定温度。The simulation software for the performance of composite computer room air conditioning (CRAC)with heat pipe is set up.Based on DeST meteorological data,the energy efficiency of air conditioning in Harbin,Beijing, Shanghai and Guangzhou is comparatively analyzed and the EER change curve shows "U"type.The lower the average outdoor temperature,the higher the EER,the better the energy saving.Compared with Guangzhou,the annual energy efficiency ratio (AEER)of air conditioning systems in Shanghai,Beijing,Harbin increases by 64%,105%,156% in turn.Based on the meteorological data of Beijing,the energy efficiency performance of air conditioning system with different room temperature is analyzed.The higher the set temperature in the computer room,the higher the EER and the better the energy saving.When the indoor temperature is set to 33,30,and 27℃,the AEER increases by 56%,42%, and 19% in turn compared to 24℃.For energy-saving and emission-reduction,the composite CRAC with heat pipe is suitable to be used in the area with low average temperature,and under the premise of meeting the reliability of electronic equipment,the setting temperature of the computer room can be increased appropriately.
