摘　　要：目前全年空调能耗一般通过性能化模拟得出,其模拟需要准确的边界条件,且计算过程烦琐,而众多大、中、小型高铁客站冷负荷采用典型设计日进行计算,无法给出全年空调系统设计预测能耗和实际运行能耗.本文利用综合部分负荷性能系数(IPLV)的概念,以夏热冬冷地区某高铁客站为例,分析并给出了其冷水机组不同负荷率下的COP和运行时长的计算方法.在设计阶段对能耗进行相对准确的简单估算,为实现定量控制空调系统能耗及碳排放目标提供支持.The annual air conditioning energy consumption is generally obtained through performance-based simulation which requires accurate boundary conditions.The calculation process is cumbersome.However,the typical design day method is usually used to calculate the cooling load in many large,medium,and small high-speed railway stations,which cannot provide the predicted annual operating energy consumption and actual energy consumption for the air conditioning system.This paper uses the concept of integrated part load value(IPLV),taking a high-speed railway station in hot summer and cold winter zone as an example,to analyse and provide a calculation method for the COP and operating time of the water chillers under different load rates.This calculation method can estimate and predict the design energy consumption,and achieve the goal of quantitatively controlling the energy consumption and carbon emissions of the air conditioning system during the design phase.
