Research and Design Optimization of Metro Vehicle Air-conditioning Condensate Water In-garage Discharge

In order to study the optimal air-conditioning condensate water discharge scheme, a centralized discharge scheme is put forward from the angle of condensate water discharge structure. By measures including adding condensate water tank, electromagnetic control valve and so on, the condensate water in operation can be automatically stored, and the drainage outlet can be adjusted to the central position at the bottom of the vehicle. Engineering practice has proved that, compared with drainage ditch and drainage slope, the optimization of vehicle condensate water drainage structure can save 90% of the engineering cost, while having obvious advantages in overhaul impact, maintenance and appearance.
