地下铁路车站采用既有集中冷站供冷经济性分析

Economic Analysis of Using Existing Centralized Cold Station in Underground Railway Station

结合工程实例,阐述了某地下铁路车站的车站规模及空调负荷特点。根据车站周边集中冷站的接驳及运行费用等情况,利用动态经济评价法,在全生命周期内,对比分析采用既有集中冷站冷源与采用常规冷源的经济性。经计算分析,在全生命周期内,采用既有集中冷站冷源的经济性相当,社会效益及环境效益明显。

This paper expounds the station scale and the characteristics of air conditioning load of an underground railway station with an engineering example.According to the connection and operation cost of the central cold staion around the station,the dynamic economic evaluation method is used to compare and analyze the economy of using the existing central cold station cold source and the conventional cold source in the whole life cycle.Through calculation and analysis,the economy of the existing centralized cooling station is equivalent,and the social and environmental benefits are obvious in the whole life cycle.
