The invention discloses a rail transit air conditioner air supply assembly and a refrigerating/heating method, and belongs to the field of rail transit. The assembly comprises an air inlet, a fan, anair conditioner air supply pipeline, an air outlet, an air volume adjusting valve, an air pressure sensor and an air pressure buffer. Firstly, passenger feature information is acquired according to real-time image information in each compartment of a traffic vehicle; and then for different vehicle types and passenger distribution models, obtaining the air volume required below each air volume adjusting valve through CAE simulation, and calculating the rotating speed of the fan. And calculating the ventilation area of each air volume adjusting valve according to the heat required by the refrigeration/heating of the temperature field under each air volume adjusting valve, and finding out the opening angle corresponding to each air volume adjusting valve. The fan determines the rotating speedaccording to the total air volume required by all the different air outlets; Meanwhile, the air pressure sensor monitors air pressure fluctuation in the air duct in real time, buffering is conductedthrough the air pressure buffer, and large air pressure fluctuation is avoided. The air volume of each air outlet is different, the comfort level of passengers is improved, and unnecessary power consumption is avoided.

    本发明公开了一种轨道交通空调送风组件及制冷/热方法,属于轨道交通领域。该组件包括进风口,风机,空调送风管道,出风口,风量调节阀,气压传感器和气压缓冲器。首先根据交通车辆各车厢内实时图像信息,获取乘客特征信息。然后针对不同的车型和乘客分布模型,通过CAE仿真获取各风量调节阀下方所需风量,计算风机的转速。根据各风量调节阀下温度场制冷/热所需的热量,计算各风量调节阀的通气面积,找到各风量调节阀对应的开度角。风机按照所有不同出风口所需的总风量确定转速;同时气压传感器实时监测风道内气压波动,由气压缓冲器进行缓冲,避免产生较大的气压波动。本发明使各出风口风量不同,提升乘客舒适度,避免不必要的电力消耗。
