The invention relates to the technical field of air conditioners, and provides a vehicle air conditioner air volume control method, an air conditioning unit and a rail transit vehicle. The vehicle air conditioner air volume control method comprises the following steps that the indoor temperature of a vehicle and the passenger carrying rate in the vehicle are obtained; the indoor temperature is compared with the outdoor temperature, the passenger carrying rate in the vehicle is compared with a preset passenger carrying threshold value of the vehicle, and the air volume flowing through the fresh air pipeline and the air volume flowing through the air return pipeline are adjusted according to the comparison result; wherein when the air volume flowing through the fresh air pipeline and the air volume flowing through the air return pipeline are adjusted, if the indoor temperature is larger than the outdoor temperature, and the passenger carrying rate is smaller than a preset passenger carrying threshold value, the fresh air pipeline is adjusted to be in an all-pass state under the refrigeration working condition. According to the control method, outdoor low-temperature air is used for assisting in refrigeration, the effects of energy conservation and emission reduction are achieved, the stuffiness feeling of passengers in the compartment is effectively avoided, and the riding comfort of the passengers is improved.
本申请涉及空调技术领域,提供了一种车辆空调风量控制方法、空调机组以及轨交车辆。所述车辆空调风量控制方法包括以下步骤:获取车辆的室内温度和车辆内的载客率;将室内温度与室外温度进行对比,将车辆内的载客率与车辆的预设载客阈值进行对比,并根据对比结果调节流经新风管路的风量和流经回风管路的风量;其中,在调节流经新风管路的风量和流经回风管路的风量时,若室内温度大于所述室外温度,且载客率小于预设载客阈值,则在制冷工况时调节新风管路处于全通状态。该控制方法利用了室外低温空气辅助制冷,起到了节能减排的效果,并有效避免了车厢内乘客出现闷热感,提高了乘客的乘坐舒适度。
