夏热冬暖地区地铁车站水冷直膨式空调机组的综合部分负荷性能指标评价

Evaluation of Load Performance Indicators for IPLV of Direct Expansion Air Conditioning Unit in Hot Summer and Warm Winter Zone Station

对地铁车站水冷直膨式空调机组综合部分负荷性能指标(IPLV)的评价方法进行研究。以IPLV的评价理论为指导,结合广州地区的气象条件和地铁典型车站,得出夏热冬暖地区地铁车站公共区的建筑热负荷特性,分析并计算IPLV的权重系数,讨论水冷直膨机组名义工况及部分负荷的测试工况条件,确定了适用于夏热冬暖地区地铁车站水冷直膨式空调机组IPLV的计算公式。为我国城市轨道交通车站直膨式空调机组国家标准制定提供参考。

The evaluation method about integrated part load value (IPLV) of water-cooled direct expansion air conditioning unit at metro station is researched.According to the evaluation theory of IPLV, and combined with the meteorological condition and representative metro stations in Guangzhou City, the building heat load characters of metro station public area in hot summer and warm winter zone are obtained.By analyzing and calculating the weight coefficients of IPLV, the nominal condition and test condition of water-cooled direct expansion air conditioning unit with partial load are discussed.On this basis, the calculation formula of water-cooled direct expansion air conditioning unit IPLV is determined.This research provides a reference for the formulation of national standards of direct expansion air conditioning unit at metro stations.
