About the overall structure and operation of the air conditioning system of the EMU: Under normal circumstances, the air conditioning unit is installed at the top of one end of the vehicle, and the mixed air box and the pressure wave protection device are respectively arranged on both sides of the air conditioning unit, and the end of the mixed air box is a return air outlet. The fresh air enters the mixing air tank through the pressure wave device and mixes with the return air in the mixed air tank to form mixed air. The pressure wave protection device is used for fresh air filtration and eliminates the effects of pressure waves formed by high-speed motion.

The air conditioning unit is provided with a filter, a heater/evaporator, a blower and the like. The mixed air is filtered through the filter and then enters the heater/evaporator for heat/humid exchange treatment. After the treatment, it becomes clean hot/cold air, and the clean hot/cold air is sent by the blower of the air conditioning unit along the length of the vehicle body ( Vertical) set the main air duct. In the winter, the heater is used to heat the air, and in the summer, the air is cooled by the evaporator. A part of the air in the private room returns to the mixed air tank, and a part of the air passes through the exhaust air exhaust duct on the vehicle and the waste exhaust duct under the vehicle, and is collected in the waste discharge unit, and is discharged to the outside of the vehicle under the power of the waste discharge unit.

The main air duct is arranged along the longitudinal center of the vehicle body, and is hoisted on the roof of the vehicle. A plurality of supporting air ducts are connected on both sides of the main air duct, and the supporting air duct is used for connecting the main air duct and the air duct. The cold/hot air enters the compartment along the main duct and the branch duct, respectively, and is assigned to each of the compartment areas by a corresponding duct (described below) in the booth. The air duct system between the rooms is described in detail below. The lower pavilion refers to the air duct for the lower pavilion area, and the upper pavilion refers to the air duct for the upper pavement area.

In the embodiment, the cavity of the upper sunshade curtain is used as the upper paving air duct, attached to the side wall, and the upper paving Wind tunnel 2 and upper side window 85 The same width. An interface 24 is formed in the cavity forming the upper air duct 2 for connection with the air duct. That is to say, the supporting air duct directly supplies air to the air duct 2, and since the supporting air duct is a plurality of air ducts arranged side by side, the upper air duct 2 and the cross wall air duct 3 can share a branch air duct to obtain a fresh air. It is also possible to separately set a separate branch duct to take fresh air from the main duct.

As another embodiment, the upper air duct 2 may also be disposed in the side wall, and the upper air duct 2 is formed by the sealing cavity of the profile cavity constituting the side wall, and the upper air duct 2 and the upper side window 85 are formed. The same width.

As shown in FIG. 6, the side window 85 of the upper compartment of the compartment forms a gap with the curtain covering cover 72, respectively, which serves as an upper air supply opening 44, and the upper air supply opening 44 communicates with the upper air duct 2. The fresh air enters the paving duct 2 from the branch air duct, and then blows out from the longitudinally disposed upper air duct 44 along the side window toward the lower side (with some inclination), not directly blowing to the passenger, and the air outlet is invisible from the side window edge. .

Obviously, in the first embodiment, the upper and lower berths of the booth are separately provided with air ducts for blowing air, and the air supply for the lower shed is not blocked by the upper paving beds, thereby improving the comfort of the lower berth.

Fig. 8 is a schematic view showing the wind direction of the fresh air flowing into the corridor from the main air passage into the compartment after the first air passage.

Referring to FIG. 7-8, using the air duct system of the sleeper compartment of the first embodiment, fresh air (hot air or cold air) enters the upper and lower paved areas of the booth from the main air passage through the support air passage to provide warm air for the private room. Or cold wind. The main air duct 95 is arranged along the longitudinal center of the vehicle body, and is hoisted on the roof of the vehicle.
