双碳背景下地铁通风空调风系统设计优化思路再探讨

Further Discussion on the Design Optimization of Ventilation and Air Conditioning System in Metro under Double Carbon Background

从既有运营线路地铁车站的“痛点”分析出发,结合传统地铁通风空调风系统设计方案带来的弊端情况,反思当前被广泛采用的方案的合理性和优化空间,回归暖通专业本原,提出地铁车站大系统“4单4脱离”、小系统“区域内平衡单系统”、出入口通道和消防专用通道兼作新风道等优化思路,大大简化地铁通风空调风系统管线、减少地面风亭数量和体量,从而简化车站综合管线布置、提高运营维保效率,减少投资,为双碳目标背景下新建城市地铁和城际及市域线路车站通风空调设计提供新的优化方向和思路。

Based on the analysis of the"pain points"of the existing operating subway stations,combined with the malpractice of the traditional subway ventilation and air conditioning system design schemes,the rationality and optimization space of the current widely adopted scheme are reconsidered.This paper returns to the HVAC professional principles,and puts forward the subway station"4 singles 4 separations"public area air conditioning system,"regional balance single system"equipment area air conditioning system,entrance channel and fire special channel as a new air duct optimization idea,etc.It greatly simplifies the subway ventilation and air conditioning system pipelines,and reduces the number and volume of ground air kiosks,thereby simplifying the station comprehensive pipeline layout,improving operation and maintenance efficiency,reducing investment,and providing new optimization direction and ideas for ventilation and air conditioning design of new urban subway and intercity and city line station under the background of double carbon target.
