Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vehicle air conditioner, and particularly to a vehicle air conditioner suitable for air conditioning existing vehicles.

[Conventional technology]

Conventional vehicle air conditioners have been configured to be mounted on the roof of a vehicle as described in Japanese Utility Model Application No. 59-120620. With this configuration of mounting on the roof, the space in the passenger compartment can be expanded to the maximum, and the arrangement of equipment under the floor will not be affected.

Incidentally, in recent years, there has been a trend to install air conditioning in existing vehicles in order to improve services for passengers, and in order to secure space in the passenger cabin, a configuration in which the air conditioner is mounted on the roof may be considered.

[Problem that the invention seeks to solve]

However, when installing an air conditioner on the roof of an existing vehicle, it is necessary to cut out a portion of the roof where the air conditioner will be installed and install reinforcing material. In the case of installation, the air conditioner and the roof of the vehicle must be sufficiently sealed to prevent rain leakage, and the problem with existing vehicles is that the roof plates deform, making the work extremely difficult.

The purpose of Zero-Hatsumen is to provide a vehicle air conditioning system that can be installed without major modification of the existing vehicle itself when air-conditioning the existing vehicle.

[Means for solving problems]

The above object is achieved by installing the main body of the air conditioner inside the vehicle and installing the exhaust air from the outdoor heat exchanger forming the air conditioner on the roof.

[For production]

According to the configuration described above, the exhaust air from the outdoor heat exchanger that constitutes the air conditioner installed inside the vehicle is discharged through the ventilation opening installed on the roof of the vehicle. There is no need to cut out or install reinforcing materials, and there is no need for complicated work such as installing sealing materials, so it can be easily installed in existing vehicles and can be air-conditioned.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 is a vehicle, and 2a and 2b are air conditioner main bodies installed at diagonal positions of the corners of the vehicle 1 in the longitudinal direction. 3g and 3b are the air conditioner main bodies 2a and 2

Reference numerals 5a and 5b are exhaust ducts connected to the rising ducts 4a and 4b and installed corresponding to the exhaust vents on the roof. Note that the exhaust port n is an existing ventilation opening in the vehicle 1, and this opening is used. Reference numerals 6a and 6b are exhaust fans for exhausting air provided above the exhaust outlet device, and the upper part is covered with a cover 13. 7 is an entrance/exit provided on the side of the vehicle l, and 8 is a through passage provided at the end of the vehicle. Reference numeral 9 denotes a door provided in a manner that can be opened and closed in correspondence with the through passage 8, and is housed in the door pocket 11. Reference numerals 10a and 10b are air intake ports provided on the side surfaces of the vehicle to take in outside air supplied to the indoor heat exchanger. 14 is a compressor provided with the outdoor heat exchanger 15, and 16 is the air intake port 10a, 10b.
This is an outdoor fan that takes in outside air from the indoor heat exchanger and efficiently blows the air. Reference numeral 17 denotes an indoor heat exchanger that exchanges heat with the circulating air from inside the vehicle taken in by the indoor fan 18 via the return grill (9) to obtain conditioned air. Reference numeral 19 denotes a communication duct for supplying the conditioned air discharged from the indoor fan 18 to the air conditioning ducts 3a, 3□, I・ゞζ '3', 'b;

This is a blowout grille that uniformly discharges conditioned air from 3b into the vehicle interior.

In such a configuration, to explain its function, the air conditioner a! The high-temperature, high-pressure refrigerant discharged from the compressors 14 of 2a and 2b enters the outdoor heat exchanger 15, where it enters the air intake port 1.
It is cooled by exchanging heat with the outside air taken in from 0a and 10b. Then, the refrigerant condenses to become a liquid refrigerant and enters a pressure reducing mechanism (not shown, generally using an expansion valve or a capillary tube).

Here, it enters the indoor heat exchanger 17 as a two-phase fluid containing gas and liquid, and performs a cooling effect while exchanging heat with the circulating air circulated from the inside of the car via the return grill (9) and evaporating. It becomes a gas refrigerant and returns to the compressor 14. The cooling effect of the indoor heat exchanger 17 turns the circulating air into conditioned air, that is, cold air, and the conditioned air is sent to the communication duct 19 and the air conditioning duct 3 by the indoor fan 18.
It is supplied into the vehicle via the air conditioning ducts 3a and 3b and from the outlet grilles 21 of the air conditioning ducts 3a and 3b.

On the other hand, the air that has cooled the outdoor heat exchanger is passed through riser ducts 4a, 4b and exhaust ducts 5a, 5b.

It passes through the exhaust port n and is discharged to the outside of the vehicle by the exhaust fans 6g and 6b. Here, the cover is the exhaust fan 6a.

6b from being directly exposed to wind and rain, and also prevents rainwater from entering the interior of the vehicle through the exhaust port n when it rains. As the exhaust port n, the garland-type ventilation port n installed on the roof of the vehicle l can be used as is, as described above, and there is no need to cut out the roof hill or install reinforcing material when modifying the air conditioning system. becomes.

According to such a configuration, the modification work performed on the vehicle l when installing air conditioning requires installing the air intake port 10a on the side wall.
, 10b (there is no need to perform complicated work such as cutting out the roof 12 and installing reinforcing materials. Also,
The air conditioner bodies 2a and 2b are installed indoors, and to prevent rain from leaking from one part of the roof, it is only necessary to cover the exhaust port n with a cover, which is much easier than with conventional roof-mounted air conditioners. be. Furthermore, rising ducts 4a and 4b.

Since the exhaust ducts 5a, 5b and the air conditioning ducts 3a, 3b are only added later when the air conditioner is remodeled, the work is easy and can be done at low cost.

Furthermore, since the air conditioner bodies 2a and 2b are installed on the floor of the vehicle 1, wiring work to the roof is not necessary. Further, since the air conditioner bodies 2a and 2b are provided at the end of the vehicle and located close to the switchboard, wiring work is very easy. In addition, by installing it at the end of the car, the space in the area with the lowest passenger density can be used effectively, and the appearance of the inside of the car will not be significantly impaired.

Next, another embodiment of the present invention will be described with reference to FIG.

In the same figure, the same reference numerals as in the previous embodiment indicate the same members. The difference between this embodiment and the previous embodiment is the air conditioner main body 2c.

2d is provided at one end in the longitudinal direction of the vehicle 1, and the exhaust duct 6 is shared.The exhaust air from the two rising ducts 4c and 4d is combined and guided to the exhaust fan 5, from where it is sent to the outside. The point is that the structure is such that it is discharged at the same time.

According to such a configuration, only one unit is required for exhausting air, so the overall configuration is simple, and air and sub-modifications can be done easily.
Even simpler and easier to do.

Next, another embodiment of the present invention will be described with reference to FIG.

This embodiment replaces the exhaust fan in the other embodiments with the following:
The two exhaust fans 26a and 26b are used to improve exhaust capacity.

According to such a configuration, noise reduction can be achieved when obtaining the same exhaust capacity. In addition, the capacity of the air conditioner can be improved.

In the above-mentioned embodiments, an example of a cooling device has been described as an air conditioner, but the present invention can provide similar effects even when a heat pump air conditioner is used as the air conditioner.

[Effects of the Invention] As explained above, according to the present invention, it can be installed in an existing vehicle with a simple operation, and the vehicle can be easily air-conditioned.
