摘　　要：为了降低数据中心制冷系统能耗,解决氟泵热管复合空调夏季耗电量大的问题,通过在冷凝器外侧加装喷雾冷却装置提高机组能效,并在不同工况和不同城市分别对其进行性能研究和适用性分析。结果表明:在室外温度为15、25、35℃工况下,与未安装喷雾冷却装置相比,氟泵热管复合空调的制冷消耗总功率分别从3.44、4.51、6.48 kW降低至2.81、3.66、4.89 kW,能效比(energy efficiency ratio,EER)分别提高了13.4%、27%、30.7%。进一步分析显示,在哈尔滨、北京、昆明、上海、广州五座典型城市中,全年能效比(annual energy efficiency ratio,AEER)分别提高了4.16%、6.69%、9.88%、10.76%、19.65%,并且空调的能效比提高率随着室外温度的升高而增大,在中、高温时长占比较大的城市节能效果更加显著。To reduce the energy consumption of the refrigeration system of the data center and solve the problem of high power consumption of refrigerant pump heat pipe composite air conditioner in summer,the energy efficiency of the unit was improved by installing a spray cooling device on the outside of the condenser,and the performance research and applicability analysis were carried out under different working conditions and in various cities.The results show that the total refrigeration power of fluorine-pump heat pipe composite air conditioner was reduced from 3.44,4.51,and 6.48 kW to 2.81,3.66,and 4.89 kW,under the conditions of at 15℃,25℃,and 35℃outdoor temperatures,and the energy efficiency ratio(EER)increased by 13.4%,27%,and 30.7%,respectively,compared with that without spray cooling device.Further analysis shows that in the five typical cities of Harbin,Beijing,Kunming,Shanghai,and Guangzhou,the annual energy efficiency ratio(AEER)increased by 4.16%,6.69%,9.88%,10.76%,and 19.65%respectively.The EER improvement rate of air conditioning increased with outdoor temperature.The energy-saving effect was more significant in cities with a large proportion of medium and high-temperature duration.
