摘　　要：对北京地区某数据中心空调系统能效进行全年动态模拟计算,分析系统实际冷负荷率及冷水机组能效对系统能效的影响。结果表明:采用冷水机组A时,空调系统在负荷率100%下全年平均设计能效比为9.61,远低于负荷率70%时全年平均设计能效比;在负荷率70%下,与采用冷水机组A相比,采用与其具有相同制冷量但不同COP的冷水机组B时,空调系统全年平均设计能效比提升0.54。A year-round dynamic simulation is conducted on the energy efficiency of the air-conditioning system of a data center in Beijing.The influence of actual cooling load ratio and energy efficiency of the water chiller on the system energy efficiency is analy-zed.The results show that when utilizing water chiller A,the air-conditioning system obtains an annual average design energy efficiency ratio(EER)of 9.61 at 100%load ratio,which is much lower than the EER achieved at 70%load ratio.At 70%load ratio,the use of water chiller B,which has the same cooling capacity but a different coefficient of performance(COP),results in an increase of 0.54 in the annual average design EER of the air-conditioning system,compared with using water chiller A.
