The invention belongs to the technical field of air conditioners, and aims to solve the problem that a side ventilation opening of an existing vehicle-mounted top-mounted air conditioner is easily interfered by environmental stroke, so that the air volume of an outer air duct is unstable. In order to achieve the purpose, the vehicle-mounted top-mounted air conditioner and the control method thereof and the vehicle are provided, the vehicle-mounted top-mounted air conditioner is installed on the vehicle and comprises a shell and an outer air duct corresponding to an outdoor heat exchanger, the outer air duct comprises a plurality of ventilation openings formed in the side portion of the shell in a surrounding mode, and each ventilation opening is provided with an air door mechanism; an air pressure sensor is arranged near each ventilation opening, the vehicle-mounted top-mounted air conditioner comprises a controller connected with the air door mechanisms and the air pressure sensors, and the control method comprises the steps that the air pressure value of each ventilation opening is obtained, and the air door mechanisms are selectively controlled to open the corresponding ventilation openings according to the air pressure values; therefore, the airflow flow of the ventilation opening is matched with the heat exchange amount of the outdoor heat exchanger, and the service life of the compressor and the refrigerant circulation pipeline is prolonged.
本发明属于空调技术领域,旨在解决现有车载顶置式空调器侧部通风口容易受到环境中风的干扰导致外风道的风量不稳定的问题。为此目的,本发明提供了一种车载顶置式空调器及其控制方法、车辆,车载顶置式空调器安装于车辆,其包括壳体以及与室外换热器对应的外风道,外风道包括围设在壳体侧部的多个通风口,每个通风口设置有风门机构,每个通风口的附近均设置有风压传感器,车载顶置式空调器包括与风门机构和风压传感器连接的控制器,控制方法包括:获取每个通风口处的风压值,根据风压值选择性地控制风门机构打开对应的通风口,从而使通风口的气流流量与室外换热器的换热量相匹配,延长了压缩机和冷媒循环管路的使用寿命。
