北方地区地铁高架站热回收型多联机空调适用性分析

Analysis of Heat Recovery Multi-connected Air-conditioning for Elevated Metro Station in Northern Regions

基于北方严寒和寒冷地区的地铁高架站,冬季车站站厅及设备管理用房人员房间有供热需求,同时车站设备用房存在大量散热需排除余热的情况,提出设置热回收型多联机,满足站内同一时间供冷和供热,相比与设备房间和人员管理房间分开独立设置空调,具有一定的节能优势。本文以某地铁高架站为例,从投资及运行能耗方面,分析探讨热回收型多联机空调在北方地区高架车站的适用性。

Based on elevated metro station in the severe cold and cold regions in the north,the concourse and equipment management personnel rooms have heating needs.At the same time,there is a large amount of heat dissipation in the station equipment room that needs to be removed from the waste heat.Setting up a heat recovery type multi machine,and satisfy simultaneous cooling and heating within the station.Compared with the separate setting of the machine with the equipment room and the personnel management room,it has a certain energy-saving advantage.This article takes an subway elevated stations as an example to analyze and explore the applicability of heat recovery type multi-connected air-conditioning in elevated metro station in northern China from the perspectives of investment and operational energy consumption.
