西安地铁车站环境实测及公共区空调负荷计算分析
Field measurement of Xi''an Metro station environment and analysis of air conditioning load for the public zone

基于对西安地铁2号线纬一街站车站公共区、站台隧道、活塞风井、排热风道和室外空气的温度和相对湿度的逐时监测,通过负荷计算及理论分析车站公共区空调负荷逐时变化规律并提出负荷计算建议。通常负荷计算中是按照规范中的规定,以晚高峰为基础取定常值。研究结果表明:虽然早高峰温度低但相对湿度大,加之早高峰客流量常常大于晚高峰,致使地铁实际运营中车站公共早高峰空调负荷时常大于晚高峰。建议空调负荷计算中综合考虑早晚高峰的峰值负荷。
According to the monitoring data of temp rature and relative humidity of Xian Metro line 2 Wei Street Station ( i.e. public zone, station tunnel, piston shaft, heat exhaust duct and externalair), the load of air-conditioning and theoretical analysis are calculated. This paper reveals the hourly change rule of the public zone air-conditioning load,and put forward some suggestions. We calculate the public zone air-conditioning load according to the regulations in design specification,based on evening peak get the constant value.In reality,morning peak’s passenger flow is bigger and the air relative humidity is higher. Then the load of morning peak and evening should be rationally considered in the calculation of public zone air-conditioning load
