摘　　要：为解决现有中央空调制冷机房运行能效比测试方法测试周期太长或未充分考虑不同负荷工况下制冷机房能效等不足,本文通过理论与实测相结合的方式,提出了一种夏热冬暖地区制冷机房系统运行能效比连续7日测试方法。并通过同一城市不同建筑类型、同一气候区域不同城市共7个典型建筑进行了可行性与适用性分析,经典型建筑制冷机房连续7日测试能效比与全年平均运行能效比进行偏差率分析,发现偏差率在±5%以内的平均占比59%,偏差率在±10%以内的平均占比98%。结果表明,在样本建筑中制冷机房系统运行能效比连续7日测试方法具有一定的可行性、适用性。In order to solve the problem of the existing testing methods for energy efficiency ratio in central air conditioning chiller plants,which either have excessively long testing periods or fail to adequately consider the efficiency under different load conditions,this study proposes a continuous 7-day testing method for the energy efficiency ratio of chiller plant systems in hot summer and warm winter zone.By combining theoretical analysis with practical measurements,the study analyzes the feasibility and applicability through testing in seven typical buildings of different building types both within the same city and different cities within the same climatic zone.The deviation analysis of the energy efficiency ratio between the continuous 7-day testing and the average annual operating efficiency ratio shows an average proportion of 59%within±5%deviation and an average proportion of 98%within±10%deviation.The results indicate that the continuous 7-day testing method for the energy efficiency ratio of chiller plant systems is feasible and applicable.
