二、改善车内热力状况的可能性和对空调设备的技术要求 1.车内空气湿度和必需产冷量与再循环空气量及进热量之间的关系外气进风量是根据车内二氧化碳含量在满员时不超过规定值这一条件确定的。再循环空气量是按照车内有最适宜的温湿度条件和产冷量最小的要求而决定的。空调客车没有专门的调湿装置,因此当冷却外气与再循环空气的混合空气时,在潮湿适中的气候条件下,通常在制冷机蒸发器上凝聚水份,而使送入车内的空气含湿量降
Second, the possibility of improving the thermal status of the car and the technical requirements of air-conditioning equipment 1. Car air humidity and the necessary capacity and the amount of recycled air and heat into the relationship between the amount of air into the air volume is based on the car’s carbon dioxide content In the full staff does not exceed the provisions of this condition to determine. The amount of recirculated air is determined according to the optimum temperature and humidity conditions in the car and the minimum cooling requirements. Air-conditioned buses do not have a special humidity control device, so when cooling the mixed air of the outside air and the recirculating air, moisture is generally condensed on the evaporator of the refrigerator in moist humid climates, so that the air Decreased moisture content
