用于干燥地区的无动力汽车空调的研究

Research on an Energy-saving Bus Air Conditioners Used in Dry Areas

新冠病毒在人群密集且封闭的汽车中能够快速传播,且确诊人数随空气温度和湿度的降低而升高,因此传统汽车空调不利于传染疾病的防控。无动力汽车空调利用汽车行驶中空气的相对运动产生的动能形成送风气流,利用喷管引射原理使超声波雾化水与空气混合实现对空气的降温效果,其车内送风温度和湿度比传统空调的高。同时该装置采用的全新风直流式运行模式能有效避免污染物滞留从而减少感染。研究还表明,该装置能降低汽车空调投资和运行能耗,避免氯氟烃类制冷剂对环境的影响。

The new coronavirus can spread rapidly among people in enclosed vehicles.Some researches revealed that the number of confirmed cases increased with the decrease of air temperature and relative humidity.Therefore,traditional bus air conditioners could not prevent the spread of the disease.The kinetic energy generated by the relative movement of the air while the bus is moving pushes the air go into the air conditioner and then mix with water mist which is ejected from a Ultrasonic atomizer.After that the air is cooled and supplied to the bus.The air supply temperature and relative humidity are higher than the supply air’s from traditional bus air conditioners.The direct primary air conditioning system can effectively avoid the retention of pollutants and reduce infection.The study also shows that the device can reduce the investment and operating energy consumption of automobile air-conditioning,and avoid the impact of chlorofluorocarbon refrigerants on the environment.
