Detailed Description
The invention will be further described with reference to the following examples.
The lower induced air structure of the bus air conditioner in the embodiment comprises air pipes arranged in a bus, wherein the air pipes comprise an induced draft fan air pipe 1 and a direct induced draft pipe 2, one end of the direct induced draft pipe 2 is communicated with the air conditioner 3 through an adapter, and the other end of the direct induced draft pipe 2 is arranged above a chassis of the bus; one end and last wind channel 4 intercommunication of draught fan tuber pipe 1, the other end setting of draught fan tuber pipe 1 is in the chassis top. Most of hot air is delivered to the feet of passengers in winter, so that the feet of the passengers are quickly heated when the passengers take the bus in winter, the hot air flows from bottom to top, and the hot air is discharged from the top of the bus, so that the hot air is discharged from top to bottom simultaneously, and the thermal comfort is good.
Draught fan tuber pipes 1 set up in 4 both ends in last wind channel, evenly carry the hot-blast in the wind channel 4.
Draught fan 11 is arranged on draught fan air pipe 1, increases hot-blast delivery rate, accelerates the heating of foot.
The installation mode of the induced draft fan 11 is that holes are formed in the positions, where the induced draft fan 44 needs to be placed and the induced draft fan passes through the induced draft fan air pipe 1, on the lower plates of the upper air ducts 4 on the two sides of the vehicle, so that the induced draft fan air pipe 1 can conveniently pass through the holes. Wherein the induced draft fan 11 is fixed on the lower plate of the upper air duct 4 at the two sides of the vehicle, the upper end of the air pipe 1 of the induced draft fan is connected with the outlet of the induced draft fan 11, and the lower end of the air pipe is led to the upper part of the feet of the passengers.
Draught fan tuber pipe 1 sets up on the internal surface of automobile body wall, direct induced duct 2 sets up on the internal surface of automobile body wall.
The vehicle chassis is provided with a PTC5, and the PTC5 is arranged at a position opposite to a middle door at a driver, so that the temperature in the vehicle is not reduced during defrosting.
As another embodiment, the induced draft fan 11 may be disposed in the upper air duct 4, and an air outlet of the induced draft fan 11 is communicated with one end of the induced draft fan air duct 1, so that the induced draft fan 11 is located inside the upper air duct 4, thereby increasing the space inside the vehicle. Draught fan tuber pipe 1 sets up in the inside of automobile body wall, increases the car inner space, direct induced duct 2 sets up in the inside of automobile body wall, increases the car inner space.
As another embodiment, only the induced draft fan air duct 1 or the direct induced draft duct 2 can be selectively used in the vehicle, and whether the PTC5 is used or not can be selectively used, and meanwhile, the number and the positions of the induced draft fan 11, the induced draft fan air duct 1 and the direct induced draft duct 2 can be randomly selected.
Description of the principle: after the heating mode of the air conditioner is started, part of hot air is directly led to the feet of passengers by the air guiding pipes, so that the feet of the passengers are rapidly heated, the thermal comfort is improved, meanwhile, the hot air blown out by the air guiding pipes above the middle door is blown out through gaps of the air channels, and a layer of vertical hot air curtain is formed at the middle door; the other part of hot air is directly blown into the upper air duct from the air outlet of the air conditioner, and then is sucked by the fan and led to the feet of passengers along the air duct; and a small amount of hot air is blown out from an air outlet of the upper air duct. The hot air is discharged from the upper part and the lower part simultaneously, and the thermal comfort is good. When the air conditioner runs for about 40min, defrosting is started, and heating is carried out through the PTC, so that the temperature in the vehicle is not reduced in a defrosting stage.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
