地铁设备管理用房风冷多联系统运行方案研究
Research on operation schemes of air-cooled multi-connection systems for subway equipment management rooms
摘要：
地铁车站设备管理用房通风空调系统能耗是地铁车站能耗的重要组成部分。近年采用风冷多联系统作为主要空调系统，并设置机械通风系统的项目逐渐增多。针对该类型空调方案的全年运行方案尚缺乏相关研究。本文选取某地铁标准车站，建立了全年逐时能耗分析模型，分析对比了不同气候区多种运行方案下的全年运行能耗。研究表明，对于大部分地区的典型车站（单位体积发热量≤0.023 kW/m3），能效优先运行方案与风冷多联系统优先运行方案的全年运行能耗差别小于10%，综合考虑运行能耗和运行方案的实施复杂性，大部分地区地铁车站设备管理用房可以采用全年风冷多联系统优先运行方案。
Abstract：
The energy consumption of ventilation and air conditioning system in the equipment management room of subway station is an important part of energy consumption of subway station. In recent years, the number of projects using air-cooled multi-connection systems as the main air conditioning systems and setting up mechanical ventilation systems has gradually increased. There is still a lack of relevant research on the annual operation scheme of this type of air conditioning scheme. This paper selects a standard subway station, and establishes an analysis model of hourly energy consumption throughout the year to analyse and compare the annual operating energy consumption under various operation schemes in different climate zones. The results show that for typical stations with calorific values per unit volume less than or equal to 0.023 kW/m3 in most areas, the annual operating energy consumption difference between the energy efficiency priority operation scheme and the air-cooled multi-connection system priority operation scheme is less than 10%. Taking into consideration of the operational energy consumption and the complexity of the implementation of the operation schemes, the air-cooled multi-connection system priority operation scheme can be adopted throughout the year for the equipment management rooms of subway stations in most areas.
