Description

[Detailed Description of the Invention] The present invention relates to an aircraft ground air conditioning system vehicle.

When inspecting or maintaining an aircraft equipped with radar or other electronic equipment on the ground, the electronic equipment room and crew cabin, other passenger cabins for passenger aircraft, cargo compartments for cargo transport aircraft, etc. must be designated in advance. It is necessary to maintain the temperature and pressure at a temperature and pressure of
(See Publication No. 42092).

Generally, as shown in FIG. 1, this ground air conditioner vehicle has an engine or an electric motor that is the power source for the air conditioner mounted on a chassis frame 11 of a cargo truck 1 such as a cab over type that uses a diesel engine as a driving source. The air conditioner section 2 consists of a box-shaped air conditioner unit that is equipped with various equipment and devices constituting the power transmission system, refrigerant system, electrical system, heating system, etc., and is installed near the aircraft. After driving the truck 1 until the end, connect the air duct connection fitting 52 provided on the side panel 21 of the air conditioner section 2 to the inside of the aircraft with an air hose, and The controller rotates the drive source by operating various control devices and switches on the control panel 3, and sends cold or hot air into the aircraft while checking the various instruments on the control panel 3. Generally, the temperature, pressure, air volume, etc. of supply air are controlled to match the values required by the aircraft.

With conventional devices such as those described above, the operator must operate the air conditioning system and control it for long periods of time from outside the vehicle, regardless of outside air conditions such as wind, rain, sunny weather, cold or heat, etc. Also, work in extremely cold or hot weather becomes extremely harsh.

In order to solve the above-mentioned problems, it is possible to install the control panel 3 of the air conditioner section 2 inside the cabin 12 of the truck 1.
In order to cool and heat the aircraft, it is necessary to separately install an air conditioning system that uses the driving engine as a drive source, and the driving engine must continue to be operated while the aircraft is being air-conditioned, which reduces fuel consumption. increases, which is extremely inconvenient in terms of cost.

The present invention is intended to address the above-mentioned conventional problems, and will be described below with reference to the embodiments shown in FIGS. 2 to 5.

In Figures 2 and 3, cabover type truck 1
On the chassis frame 11, there is a drive source (for example, an engine) 4, a blower duct 5 equipped with a blower 6, an evaporator 7, a heater 8, etc., as well as a condenser 9, a radiator 10, and although not shown, a compressor and a liquid receiver. It is the same as the conventional configuration shown in Fig. 1 that the air conditioner unit 2 is equipped with a refrigerant system equipment and other refrigerant system equipment and covered with a panel or the like in a box shape, but in the present invention, the control A panel 3 is provided on the front panel 22 of the air conditioner section 2, and the control panel 3
The gap between the front panel 22 of the air conditioner unit 2 and the rear surface of the cabin 12 and the outer peripheral frame of the cabin 12
A flexible duct-shaped sealing member 3a is provided to seal the peripheral edge of the window hole 12a provided on the rear surface.
Switches on the front of the control panel 3 from inside the cabin 12,
Various control devices can be operated while checking various instruments.

The control panel 3 has a cabin 12 as shown in the third figure.
For example, it is provided on the left side of the front panel 22 so as to face the rear of the passenger seat 13, and the passenger seat 13 is
By switching from the forward direction shown by the solid line to the rear direction shown by the chain line in the figure, an operator can operate the control panel 3 while sitting in the rear-facing passenger seat 13.

Also, the evaporator 7 of the air conditioner's blow-off duct 5,
As shown in FIG. 4, a duct connection port 53 is provided downstream of the heater 8, and the other end of the ventilation duct 54, one end of which is connected to the duct connection port 53, is connected to the front panel of the air conditioner unit 2. It is connected to a switching damper box 55 provided at 22.

A switching damper 5 is provided in the switching damper box 55.
5a is provided, and the air flowing into the box 55 from the air duct 5 of the air conditioner through the air duct 54 is guided to either the hot air blowing nozzle section 56 or the cold air blowing nozzle section 57 by the switching damper 55a. It is configured like this. 58 is a connecting duct.

A cold air blowing nozzle section 57 and a warm air blowing nozzle section 56 provided at the upper and lower parts of the front panel 22 of the air conditioner section 2 open into the rear surface of the cabin 12, as shown in FIGS. 3 and 5. ing.

As shown in FIG. 4, an air blow adjustment device 53a is provided at the duct connection port 53 portion of the blow-off duct 5, and the opening area of the duct connection port 53 can be increased or decreased by the air blow adjustment device 53a. ing. The air blow adjustment device 53a and the switching damper 55a
Both can be controlled by operating a control operation section provided on the control panel 3.

The operation of the device of the present invention constructed as described above will be explained below.

After driving close to the aircraft and connecting the air duct connection fitting 52 and the inside of the aircraft with an air hose (not shown), the operator sits in the rear-facing passenger seat inside the cabin 12 and starts the control panel 3. Engine 4 is turned on by turning on the switch.
is activated, and in the case of cooling, the cooling cycle is activated,
In the case of heating, the heater 8 is activated, and the outside air sucked into the duct 5 from the suction port 51 by the blower 6 is cooled while passing through the evaporator 7 or
The air is heated while passing through the air, and cooled or warmed air is supplied into the aircraft through an air hose (not shown). The temperature and pressure of the blown cold air or hot air are maintained at a desired constant value by an operator checking various instruments provided on the control panel 3 and controlling various control devices on the control panel 3.

In this case, the operator operates the in-cabin air conditioning control operation section of the control panel 3 to open the hot air blowing nozzle section 56 and close the cold air blowing nozzle section 57 of the switching damper 55a during winter, for example.
Then, a portion of the hot air heated by the heater 8 passes through the air duct 54 from the duct connection port 53 and is blown into the cabin 12 from the hot air blowing nozzle portion 56, thereby heating the inside of the cabin 12.

Also, in the summer, by switching the switching damper 55a in the opposite direction to the above, the cold air cooled by the evaporator 7 is transferred from the duct connection port 53 to the blower duct 5.
4. Cold air blowing nozzle part 5 through connection duct 58
7 into the cabin 12 to cool the inside of the cabin 12.

In the above, the amount of air blown into the cabin 12 is:
It can be freely controlled by operating the air blow adjustment device 53a from inside the cabin 12.

As described above, according to the present invention, all controls such as starting and stopping the aircraft's ground air conditioning system, the temperature, pressure, and air volume of the blown air can be performed while sitting on a seat in the cabin, and the vehicle Since the air conditioning inside the cabin can be performed accurately without using the driving engine, the working environment for the operator can be significantly improved, especially when atmospheric conditions such as rain, strong winds, extremely cold, or scorching heat occur. Not only can operator fatigue be greatly reduced in extremely poor conditions, but compared to driving the vehicle's engine to air condition the cabin, a dedicated air conditioner for the cabin can be used. It is unnecessary and extremely advantageous in terms of cost, and can also significantly reduce fuel consumption, which can bring about great practical effects.
