温和地区地铁车厢夏季热环境现状调查研究*
Investigation and study on current situation of underground railway carriage thermal environment in summer in moderate zone
摘要：
以昆明地铁1，2号线为研究对象，对地铁车厢夏季热环境参数进行了测试；同时通过主观问卷得到乘客的实际热感受评价情况。实地调研得到了昆明地铁车厢热环境现状，并计算了高峰期与非高峰期乘客热中性温度与可接受温度范围。从健康、舒适、节能的角度出发，建议适当提高昆明地铁空调设定温度：高峰期间为25 ℃，非高峰期间为27 ℃。
Abstract：
Taking Kunming underground railway Line 1 and Line 2 as the research objects, tests the thermal environment parameters of underground railway carriages in summer. Obtains the actual thermal sensation of passengers by subjective questionnaires. Obtains the carriages thermal environment of Kunming underground railway through field investigation. Calculates the thermal neutral temperature and acceptable temperature range of passengers in heavy traffic and non-heavy traffic periods. From the point of view of health, comfort and energy saving, suggests to increase setting temperature of air conditioning in Kunming underground railway to an appropriate value. That is to say, 25 ℃ is for the heavy traffic period and 27 ℃ for the non-heavy traffic period.
