Embodiment 1
[0037] Embodiment 1 is basically as attached figure 1 Shown:
[0038] An air-conditioning air supply system for a rail transit vehicle, comprising a passenger interior temperature sensor, a passenger exterior temperature sensor, a return air door control module, and a fresh air door control module. The temperature sensor inside the passenger room is used to detect the temperature inside the passenger room; the temperature sensor outside the passenger room is used to detect the temperature outside the passenger room. The temperature sensor in the passenger room is set on the air return door and the air return port, and the air return port is located in the gap of the air duct. The return air position of the air conditioner in the existing rail transit vehicles is single, and the return air speed is relatively fast, resulting in large return air noise. In the present invention, the return air is carried out by utilizing the space of the air duct in the passenger room, and the ...
Embodiment 2
[0045] Embodiment 2 is basically as attached figure 2 Shown:
[0046] An air-conditioning air supply method for a rail transit vehicle, comprising the following steps:
[0047] S1: Detect the temperature in the passenger room through the temperature sensor in the passenger room; the temperature sensor in the passenger room is set at the air return door and the air return port; the air return port is located in the gap of the air duct;
[0048] S2: Detect the temperature outside the passenger room through the temperature sensor outside the passenger room;
[0049] S3: Control the opening of the return air door and the fresh air door; when the temperature in the passenger compartment reaches a high temperature threshold, control the opening of the return air door to be large, and control the opening of the fresh air door to be small.
[0050] The opening degrees of the return air door and the fresh air door include full opening, 2 / 3 opening, 1 / 3 opening and full closing. Aft...
