摘要:
［目的］为了对高温高湿地区的地铁车厢热环境进行改善及实现低碳节能目标，有必要对地铁车厢热环境的现状以及舒适性进行研究。［方法］对春秋过渡季、夏季、冬季福州地铁2号线车厢内的热环境参数进行现场测试，采用问卷调查获得车厢内乘客热舒适评价的有效问卷1 027份，分析不同群体热感觉之间的差异特性，研究不同载客量和不同天气情况下车厢内乘客的热舒适性区别，计算车厢的热中性温度。［结果及结论］乘客的主观评价与车厢实际热环境参数存在差异。夏季的热中性温度为25.11 ℃，高于车厢实际平均温度。冬季热中性温度为11.67 ℃，低于车厢实际平均温度。说明夏季车厢偏凉，应适当提高空调送风温度，冬季车厢偏热，应适当降低空调送风温度。
Abstracts:
［Objective］ In order to improve the thermal environment of subway compartment in high temperature and humidity areas and achieve low-carbon energy-saving goals, it is necessary to study the current situation and comfort of subway compartment thermal environment. ［Method］ Field tests are conducted on the compartment thermal environment parameters of Fuzhou Metro Line 2 in the spring and autumn transition seasons, summer, and winter. Meanwhile, 1 027 valid questionnaires on thermal comfort evaluation of compartment passengers are obtained by questionnaire survey. Thermal sensation differences among different groups are analyzed. Thermal comfort differences of compartment passengers under different passenger capacities and weather conditions are studied, and the compartment thermal neutral temperature is calculated. ［Result & Conclusion］ There are differences between the subjective passenger evaluation and the actual compartment thermal environment parameters. The thermal neutral temperature 25.11 ℃ in summer is higher than the average actual compartment temperature, and thermal neutral temperature 11.67 ℃ in winter is lower than the average actual compartment temperature, indicating that the compartment is too cool in summer and the set temperature of air conditioning should be appropriately increased, while compartment is too warm in winter and the set temperature of air conditioning should be appropriately reduced.
