Abstract

(57) [Abstract] [Purpose] When the air supply from the air conditioner is distributed to multiple rooms by branching the air conditioning duct, the temperature difference between the rooms is reduced to improve the habitability of the vehicle. [Structure] The air supply from the air conditioner 5 is supplied to the air conditioning duct 6 for the second floor room.
And the air-conditioning duct 7 for the first-floor room are distributed, and a drive-type damper device 9 capable of distributing the air volume is provided at the branch portions 8 of both the air-conditioning ducts 6 and 7, and the first-floor room 3 and the second-floor room 4 are provided. Each temperature sensor 10 is provided, and the drive damper 9 is operated according to the temperature difference between the temperature sensors 10 to distribute the amount of air supplied from the air conditioner 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle air conditioner for a vehicle having a private room such as a driver's cab, a crew room, and a passenger private room or a double-decker vehicle.

[0002]

[Prior Art]

 Conventionally, such an air conditioner for a vehicle distributes air supply from one or two air conditioners to a plurality of rooms by branching a duct, and air volume adjustment to each room is performed by the vehicle. At the time of new production, the diameter of the duct was changed according to the volume of each room, and an air flow distribution damper was installed to fix it.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned one cannot cope with the change in heat load such as the number of people in each room and the condition of sunlight, so that some rooms may be hot or cold.

Therefore, the present invention aims to provide a vehicle air conditioner capable of automatically adjusting the amount of air supplied from an air conditioner to each duct in response to changes in the heat load of each room. I am trying.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the vehicle air conditioner of the present invention is a vehicle air conditioner in which air supply from an air conditioner is divided into a plurality of rooms by branching ducts. A temperature sensor is provided, and a drive damper device that distributes the air supply amount from the air conditioner according to the temperature difference of the temperature sensor is provided at each branch of the duct.

[0006]

[Action]

 With this configuration, the drive damper operates according to the temperature difference of the temperature sensor arranged in each room, and distributes the air volume to each room.

[0007]

【Example】

 An embodiment in which the present invention is applied to a two-story vehicle will be described below with reference to the drawings.

The two-story vehicle 1 is provided with a normal passenger compartment 2 at the front and rear parts of the vehicle body, and a trolley corresponding to an intermediate portion between the passenger compartments 2 and 2 is bulged downward to form a passenger compartment. The second-floor room 4 is divided into two layers in the longitudinal direction of the vehicle body.

Air conditioners 5 and 5 are attached to the front and rear of the ceiling of the vehicle body, and a second floor air conditioning duct 6 is provided on the ceiling of the second floor room 4 between the air conditioners 5 and 5. Further, on the ceiling of the first-floor room 3, a first-floor room air-conditioning duct 7 branched from the second-floor room air-conditioning duct 6 is provided.

A drive damper 9 operated by a motor or a cylinder is provided at a branch portion 8 between the air conditioning duct 6 for the second floor room and the air conditioning duct 7 for the first floor room.

A temperature sensor 10 is provided in each of the first-floor room 3 and the second-floor room 4, and a wiring 12 from an air conditioning controller 11 is connected to each temperature sensor 10.

Further, a wiring 13 is connected between the air conditioning control device 11 and the air conditioner 5, and a wiring 14 is connected between the air conditioning control device 11 and the drive type damper 9.

The air conditioning control device 11 operates the drive type damper 9 according to the temperature difference detected by the temperature sensor 10 of the first-floor room 3 and the temperature sensor 10 of the second-floor room 4, and the air-conditioner 5 generates the second-floor room. The amount of conditioned air supplied to the air conditioning duct 6 and the air conditioning duct 7 for the first floor room is distributed.

Therefore, the amount of air supplied from the air conditioner 5 to the air conditioning duct 6 for the second floor room and the air conditioning duct 7 for the first floor room can be automatically adjusted according to the heat load of the first floor room 3 and the second floor room 4. The temperature difference between the first-floor room 3 and the second-floor room 4 is reduced, and the habitability of the vehicle can be improved.

[0015]

[Effect of the device]

 As described above, according to the present invention, the air supply from the air conditioner is divided into a plurality of rooms by branching the air conditioning duct, and each branch of the air conditioning duct is provided with a drive type damper device capable of distributing the air volume. Each room is equipped with a temperature sensor linked with the drive damper, and the air supply from the air conditioner is distributed according to the temperature difference of each temperature sensor. The habitability of can be improved.
