摘　　要：我国严寒地区已运营通车的地铁项目存在冬季公共区及设备区管理用房温度不达标、空气品质差等情况。以沈阳地区某地下车站为例,通过对比分析电加热供暖、多联机空调系统供暖、设备用房余热回收、再生制动能量热回收等多种新风加热方式的能耗情况,提出在严寒地区回收设备用房余热和再生制动能量余热用于新风系统加热,可以实现大幅节能效果。Metro projects operating in severe cold areas of China often face challenges such as inadequate temperatures in public and equipment management rooms,as well as poor air quality during winter.Using an underground station in Shenyang as a case study,this research compares and analyzes the energy consumption of various fresh air heating methods,including electric heating,VRF air conditioning system heating,equipment room waste heat recovery,and regenerative braking energy heat recovery.The study proposes the utilization of equipment room waste heat and regenerative braking energy waste heat for heating the fresh air system in severe cold areas.This approach can yield significant energy-saving benefi ts and ensure compliance with epidemic prevention and control regulations,within the context of the carbon peaking and carbon neutrality strategy.
