[0068] The air outlet and the return air outlet are arranged at the bottom of the air conditioning unit housing, and both face the passenger compartment of the ultra-thin rail vehicle;

[0069] The air inlet and the air outlet are arranged on the top of the ultra-thin rail vehicle shell, and both face the outside of the ultra-thin rail vehicle;

[0070] The air outlet is connected to the heat exchanger in the housing of the air conditioning unit through a first double ventilation duct, and an air outlet grille is installed at one end of the first double ventilation duct close to the air outlet;

[0071] The return air outlet is connected to the heat exchanger and the exhaust outlet through the three-air duct, and a return air grille is installed at one end of the three-air duct close to the return air outlet;

[0072] The air inlet is connected to the heat exchanger through a second double ventilation duct, and an air inlet grille is installed at one end of the second double ventilation duct close to the air inlet;

[0073] The three ventilation ducts are provided with a first valve with a controllable opening and closing state and the air flowing into the return air port flows to the heat exchanger and / or the exhaust port;

[0074] The first double ventilation duct and the second double ventilation duct are respectively provided with a second valve and a third valve which can control the opening and closing state of the ducts;

[0075] The control module is electrically connected to the air outlet grille, the air return grille, the air inlet grille, the first valve, the second valve and the third valve respectively.

[0076] In this embodiment, the first double ventilation channel and the second double ventilation channel are ventilation ducts with only two ports, and the triple ventilation channel is a ventilation duct with three ports.

[0077] In this embodiment, the air outlet grille, the return air grille, and the air inlet grille can all be controlled by the control module in terms of their opening and closing states. When they are closed, the airflow cannot enter the corresponding air duct from the corresponding air outlet.

[0078] The working principle and beneficial effects of the above technology are:

[0079] refer to Figure 2 When the control module receives a control instruction to adopt an internal circulation temperature adjustment strategy, the return air grille and the air outlet grille are controlled to be opened, and at the same time, the first valve is controlled so that the airflow flowing into the return air port only flows to the heat exchanger through the filter screen, and at the same time, the second two-way pipe is closed by controlling the third valve on the second two-way pipe, and the second valve on the first two-way pipe is controlled so that the refrigerated or heated air flowing out of the heat exchanger is discharged from the air outlet to the passenger compartment of the ultra-thin rail vehicle;

[0080] refer to Figure 3 When the control instruction received from the control module is to adopt the external circulation temperature adjustment strategy, the return air grille, the outlet air grille, and the inlet air grille are all controlled to be opened. At the same time, the first valve is controlled so that the airflow flowing into the return air port only flows to the exhaust port through the filter and is discharged from the exhaust port. At the same time, the second two-way pipe is opened by controlling the third valve on the second two-way pipe so that the air outside the vehicle flows into the heat exchanger, and the second valve on the first two-way pipe is controlled so that the refrigerated or heated air flowing out of the heat exchanger is discharged from the outlet into the passenger compartment of the ultra-thin rail vehicle;

[0081] refer to Figure 4 When the control instruction received from the control module is to adopt an internal and external circulation combined with temperature control strategy, the return air grille, the outlet grille, and the inlet grille are all controlled to be open. At the same time, the first valve is controlled to allow the airflow flowing into the return air port to pass through the filter and flow to the exhaust port and the heat exchanger at the same time, so that the air flowing into the return air port is discharged from the exhaust port. At the same time, the second two-way pipe is opened by controlling the third valve on the second two-way pipe, so that the air outside the vehicle flows into the heat exchanger, and the second valve on the first two-way pipe is controlled so that the refrigerated or heated air flowing out of the heat exchanger is discharged from the outlet to the passenger compartment of the ultra-thin rail vehicle; at this time, the gas flowing into the heat exchanger comes from outside the vehicle and inside the passenger compartment.
