本文研究了在不冷却空气的情况下，采用送风方式对客车舱内湿度的影响。根据试验结果和车厢内的湿度平衡，建立了车厢内湿度随时间变化的模型。在两辆客车上进行了湿热条件的研究。在测试期间，供暖和制冷功能被关闭。在驾驶汽车前后，分别测量了车外、送风管道内和乘用车驾驶室内的相对湿度和温度。这些测试是在20至42.9摄氏度的平均温度范围内进行的。为了建立湿度随时间变化的模型，制备了湿度天平。车厢内的人为湿度主要取决于车内温度和人的年龄，成人在20-43摄氏度的温度范围内的湿度范围为20至180克/(小时×人)，而6岁以下的儿童的湿度范围为8至19.5克/(小时×人)，温度范围为22-34摄氏度。在实验研究和所建立的模型的基础上，测定了一名成人和一名六岁儿童在车内产生的湿度。该模型可用于客车风量自动调节系统。
This paper presents research on humidity in a passenger car cabin with the use of supply ventilation without cooling the air. Based on the tests carried out and the humidity balance in the car, a model was developed for changing the humidity in the passenger car cabin as a function of time. The study of thermohumid conditions was carried out in two passenger cars. During the tests, the heating and cooling functions were turned off. The relative humidity and temperature were measured outside the car before and after driving the car and in the supply air duct and inside the passenger car cabin while driving the car. The tests were carried out for an average temperature range from 20 to 42.9 degrees C. In order to develop a model of humidity changes as a function of time, a humidity balance was prepared. Human-generated humidity in the car cabin depends mainly on the temperature inside the car and the age of the person and can range from 20 to 180 g/(h x person) for an adult in the temperature range of 20-43 degrees C, while for a child under six years old the humidity ranges from 8 to 19.5 g/(h x person) in the temperature range 22-34 degrees C. A formula of humidity generated by an adult and a child aged six years old was obtained as a function of temperature inside a passenger car. Based on the experimental research and the model developed, the humidity generated by a single adult and a six-year-old child in the car was determined. The developed model can be used in the automatic airflow adjustment systems in passenger cars.
