摘要
针对我国南方地区动车检修库夏季室内热环境问题,以南宁某动车检修库为研究对象,对室内热环境进行现场实测与调研,通过对测试结果的分析,得出该动车检修库垂直高度方向上温度出现明显的分层现象,二、三层作业平台间的平均温差在1.6℃左右,且在12:00~17:00间主要工作区域的温度均超过35℃;在横轴方向上,温度出现对称分布,中间区域的温度明显高于两侧;与温度不同,相对湿度与空间位置没有明显关系,且二者随时间的变化规律并不同步,温度最高时相对湿度最低,反之亦然,在0:00~11:00间平均相对湿度最大,为72%。所得到的温湿度数据及分布规律为该动车检修库的通风系统设计和改善提供了参考依据。
Aiming at the indoor thermal environment problem of the train service shop in the south of China in summer,a certain train service shop is taken as the research object,and the indoor thermal environment is measured and investigated on the spot.Through analysis of the test results,in the vertical height direction there is significant temperature stratification.The mean temperature difference between the second and third working platforms is about 1.6℃,and the temperature in the main working area is more than 35℃between 12:00 and 17:00.In the horizontal axis direction,there is a symmetrical temperature distribution,and the temperature in the middle area is significantly higher than both sides.Unlike temperature,relative humidity has no obvious relationship with spatial location.The relative humidity is the lowest when the temperature is the highest,and vice versa.
