摘　　要：为了准确评价数据中心用制冷剂泵-压缩机双循环单元式空气调节机的节能效果,引入全年节能率的概念,在全年需求制冷量相同(100 kW)的前提下,运用焓差法测试传统机房空调与数据中心用制冷剂泵-压缩机双循环单元式空气调节机的制冷量和制冷消耗功率。结果显示,相对于传统机房空调,数据中心用制冷剂泵-压缩机双循环单元式空气调节机的全年节能率为28.91%,具有较好的节能效果。In order to evaluate the energy-saving effect of refrigerant pumping-compressing dual cycles air-conditioner for data center accurately,the concept of annual energy-saving rate is introduced.Based on the same annual cooling capacity demand(100 kW),the enthalpy difference method is used to test the cooling capacity and cooling power consumption of traditional computer room air-conditioning and refrigerant pumping-compressing dual cycles air-conditioner for data center.The results show that the annual energy-saving rate of refrigerant pumping-compressing dual cycles air-conditioner for data center is 28.91%,which has a good energy-saving effect,compared with the traditional computer room air-conditioning.
