对于客车来讲,热工和卫生要求有特别重要的意义。一、空气参数空气的净度对旅客身体感觉有很大的影响。为了保持车内空气净度必须供给车辆一定数量的新鲜空气,并考虑在通风系统中装设相应的过滤器。为了防止灰尘从缝隙进入车内,要提高结构的气密性,并保有一定的空气增压。在空调客车中建议下列空气参数:客室空气温度夏季应是22～26℃(计算时取平均值24℃),冬季是18～22℃;空气的相对湿度应是30～60％;允许的空气温度不均匀性(在同一水平面沿车长、在同一铅垂线沿车
For passenger cars, thermal and hygiene requirements are of particular importance. First, the air parameters The clarity of the air has a great impact on the body of passengers. In order to maintain the cleanliness of the car must provide a certain amount of fresh air vehicles, and consider the ventilation system installed in the corresponding filter. In order to prevent dust from entering the car through the gap, it is necessary to improve the airtightness of the structure and maintain certain air pressurization. The following air parameters are recommended for air-conditioned buses: The air temperature in the passenger compartment should be 22 to 26 ° C in summer (average 24 ° C for calculation) and 18 to 22 ° C in winter; the air relative humidity should be 30 to 60%; the permitted air Temperature inhomogeneity (in the same level along the car length, in the same plumb line along the car
