The invention relates to a subway air conditioner fresh air volume adjusting method and system based on a passenger counter, wherein the method comprises the steps: carrying out real-time statistics of the passenger flow information in each carriage in a stop period through a passenger counter in each carriage, and transmitting the passenger flow information to a fresh air valve opening degree control module in a subway vehicle TCMS system; the fresh air valve opening degree control module performs logical judgment according to the passenger flow information and a preset fresh air valve opening degree control strategy, generates a corresponding fresh air valve target opening degree instruction and sends the fresh air valve target opening degree instruction to an air conditioning system; and the air conditioning system adjusts the fresh air volume of corresponding compartment fresh air openings according to the fresh air valve target opening degree instruction. The fresh air volume of the fresh air openings can be adjusted according to the real-time passenger flow volume in the vehicle, reasonable distribution of the ratio of the fresh air volume to the return air volume is achieved, good circulation of air in the compartment is guaranteed, fresh air energy consumption is reduced, and the return air utilization rate is increased.

    本发明涉及一种基于乘客计数器的地铁空调新风量调节方法及系统,其中方法包括步骤:利用每节车厢内的乘客计数器实时统计停站周期每节车厢内的客流量信息,并将客流量信息发送给地铁车辆TCMS系统中的新风阀开度控制模块;新风阀开度控制模块根据客流量信息和预设的新风阀开度控制策略进行逻辑判断,生成相应的新风阀目标开度指令,并将新风阀目标开度指令发送给空调系统;空调系统根据新风阀目标开度指令调节对应车厢新风口的新风量大小。本发明能够按照车内实时客流量调整新风口的新风量,实现新、回风量比例的合理分配,保证车厢内空气的良好流通的同时,节约了新风能耗,提高了回风利用率。
