The invention discloses a variable-frequency waste discharge system of a train set. The system comprises: a variable-frequency waste discharge device which is arranged under the train and is internally provided with a variable-frequency fan; an air mixing device which is arranged in the roof area in the compartment, used for mixing return air and fresh air, and is internally provided with an air speed sensor; a pressure detection device which is arranged in the train head, and is internally provided with a pressure sensor; and a fresh air device which is arranged at the train roof and allows fresh air to enter the compartment,wherein the variable-frequency fan, the air speed sensor and the pressure sensor are connected with an air conditioner controller at the end part of the compartment, and the air conditioner controller receives information of the pressure sensor and the air speed sensor and sends an instruction according to internal logic to control the working frequency of a waste discharge fan, so that the waste discharge air volume is increased or reduced, and the purpose of automatically adjusting the fresh air volume and the pressure in the compartment is achieved.

    一种动车组变频废排系统,包括设置在车下的变频废排装置,其内设有变频风机;设置在车厢内车顶区域用于混合回风与新风的混合空气装置,其内设有风速传感器;设置在车头内的压力探测装置,其内设有压力传感器;设置在车顶用于新鲜空气进入车内的新风装置,其中变频风机、风速传感器和压力传感器连接车厢端部的空调控制器,空调控制器接收压力传感器和风速传感器的信息,并根据内部逻辑发出指令来控制废排风机的工作频率,增大或减小废排风量,达到自动调节新风量和车内压力的目的。
