介绍了沈阳某地铁站一次回风空调系统及夏季空调系统送、回风量的计算方法。分析了地铁站冬季空调系统的特点,在无供热热源的情况下利用设备间的设备发热量作为供热量,对无设备发热量的管理用房可采用电供暖作为补充。在冬、夏季总供、回风量相同的基础上,对冬季各房间的温度进行了校核计算。寒冷地带的地铁站的设备间及管理用房可采用冬、夏季相同送、回风量的一次回风空调系统。牵引变电所宜采用通风系统控制室内温度。
The method of calculating the return air volume of a return air conditioning system and a summer air conditioning system at a subway station in Shenyang is introduced. The characteristics of the winter air-conditioning system in subway station are analyzed. In the case of no heat source, the heat of equipment in the equipment is used as heat supply, and the heating of equipment without heating equipment can be supplemented by electric heating. On winter and summer total supply, return air volume on the basis of the same, the temperature of each room in winter were checked and calculated. Equipment and management of metro stations in the cold areas can be used as a return air-conditioning system with the same sending and returning air volume in winter and summer. Traction substation should adopt the ventilation system to control the indoor temperature.
