Method and device for controlling make-up air system of subway

The invention discloses a method and device for controlling a make-up air system of a subway. The method comprises the following steps of acquiring outdoor meteorological parameters, and calculating an outdoor air enthalpy value according to the outdoor meteorological parameters; and generating a running control strategy of the make-up air system according to the numerical range of the outdoor airenthalpy value. According to the method, a fan is not arranged, piston air formed by running of a vehicle in a subway tunnel is used as a power source for ventilation of the system, the power consumption of the fan is reduced, the air quality in a subway station hall is effectively improved, the area of a machine room is reduced, and the construction amount of a ventilation system is reduced. 本发明公开了一种地铁新风系统控制方法及控制装置，其中，该方法包括：获取室外气象参数，根据室外气象参数计算室外空气焓值；根据室外空气焓值的数值范围生成新风系统的运行控制策略。该方法不设置风机，利用地铁隧道内车辆行驶所形成的活塞风作为系统通风的动力来源，节省风机电耗，有效改善地铁站台站厅内的空气品质，减少机房面积，降低了通风系统的施工量。
