摘要
由于民用建筑的负荷特性和地铁车站的负荷特性相差较大,而国标IPLV的取值是根据民用建筑的复合分布特点来制定的,所反映的负荷分布、权重系数和平均冷却进水温度与地铁工程差异较大,因此有必要建立与各地负荷特性相匹配的NPLV。本文基于苏州地铁车站的既有已运营数据,建立了苏州地铁的NPLV的计算公式;对近、远期苏州地铁的NPLV进行了对比分析;初步探讨了NPLV对制冷主机的选型的参考意义。
Due to the significant difference in load characteristics between civil buildings and subway stations,and the value of the national standard IPLV is determined based on the composite distribution characteristics of civil buildings,the reflected load distribution,weight coefficients,and average cooling water inlet temperature differ greatly from subway engineering.Therefore,it is necessary to establish an NPLV that matches the load characteristics of different regions.This article establishes a calculation formula for the NPLV of Suzhou Metro based on the existing operational data of Suzhou Metro stations;A comparative analysis was conducted on the NPLV of Suzhou Metro in the near and long term;Preliminary exploration was conducted on the reference significance of NPLV for the selection of refrigeration units.
