摘要
Abstract
With the continuous expansion of subway line operations,the air conditioning system,as a major energy consumer in subways,has made effective energy-saving operation an urgent issue.The author takes a standard 6-carriage station in South China as the research subject,analyzing and studying economically reasonable configurations for water system equipment and energy-efficient operational modes.Since the supply and return temperatures of cooling water are closely related to the energy efficiency of the air conditioning system,lowering the cooling water outlet temperature can significantly improve the efficiency of chillers.However,this requires a corresponding increase in the heat dissipation capacity of cooling towers.This paper comprehensively analyzes and compares the advantages and disadvantages of reducing cooling water supply and return temperatures for subway projects,proposing an appropriate cooling water supply and return temperature of 30.5/35.5 ℃.关键词
