Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an integrated air conditioner in which the inside of the machine is partitioned into an indoor room and an outdoor room by partition plates.

(b) Prior Art Conventionally, an example of the structure of this type of integrated air conditioner has been disclosed in Japanese Utility Model Publication No. 58-5875.

According to this content, the inside of the machine was partitioned by a partition plate into an indoor chamber and an outdoor chamber, and each chamber was equipped with a compressor and a heat exchanger. The refrigerant piping connecting the compressor and heat exchanger was fixed to the inner wall of the aircraft's exterior body near the partition plate using fixtures.

(c) Problems to be solved by the invention As described above, if the refrigerant piping is fixed to the inner wall of the exterior body of the aircraft using a fixture, when the exterior body is removed during service inspection, the refrigerant piping must be removed from the exterior body in advance. The drawback was that it had to be removed, making this service inspection difficult.

The purpose of the present invention is to enable easy service inspection by removing the exterior body of an integrated air conditioner.

(d) Means for solving the problem In order to achieve this objective, the present invention divides the indoor interior of the aircraft into a heat exchange room and a machine room using a horizontal partition plate, and a A notch is provided, a refrigerant pipe is accommodated in this notch, and this notch is covered with a panel.

(e) Function The refrigerant pipe is housed in the notch on the front side of the horizontal partition plate, and the opening of this notch is covered with a panel, so that when the panel is removed, the refrigerant pipe can be taken out from the opening of this notch.

(f) Example Figure 1 shows an integrated air conditioner 1 installed in a window.
FIG. Reference numeral 2 denotes a partition plate that partitions the interior of the air conditioner into front and rear parts, and is placed on a rising piece 3 (see FIG. 2) that runs approximately diagonally on the bottom plate. 4 is a condenser, and this condenser is installed so that its fins overlap in the vertical direction. Reference numeral 5 denotes an outdoor cross-flow fan, which sucks air through a ventilation grille 7 of an exterior body 6, exchanges heat with a condenser 4, and then discharges it from a discharge port 8.

Reference numeral 9 denotes a fan casing placed on a horizontal partition plate 10 while touching the front side of the partition plate 2. This horizontal partition plate 10 separates the front side of the air conditioner from the upper heat exchange chamber 11 and the lower machine room 12 ( (See Figure 2). 13 is an evaporator, and 14 is a drain receptacle formed by recessing the horizontal partition plate 10 below the evaporator 13 to receive drain water dripping from the evaporator 13. Drain receiver 1
4 is integrally formed with a drain guide 15, and this drain guide 15 is connected to the fan casing 9.
The drain guide 15 extends into the outdoor chamber 16 through the partition plate 2 , and the tip 17 of the drain guide 15 is in contact with the fin 18 of the condenser 4 . Reference numeral 19 denotes an indoor cross-flow fan supported by a horizontal plate 10 and a top plate 20 (see Figure 3). The discharge port 22 is guided by the casing 9.
It is discharged from.

FIG. 2 is a cross-sectional view showing the internal structure of the lower part of the air conditioner 1. As shown in FIG. 23 is a compressor that performs a cooling function by sending the refrigerant liquefied by dissipating heat in the condenser 4 to the evaporator 13; 24 is a motor for driving the rotating plate 25; the rotating shaft 26 of this motor is connected to the bottom plate 27;
The rotating plate 25 is supported by the rising edge 3 of the condenser 4 and passes below the condenser 4 to support a rotary plate 25 on the outside of the condenser 4. A rising piece 28 is formed on the bottom plate 27 so as to surround the lower part of the outdoor cross flow fan 5, and this rising piece 28 is connected to the above-mentioned rising piece 3 running diagonally, and the rear edge 2 is formed on the bottom plate 27.
8 (see FIG. 3) and a drain pan 29 surrounded by the rising pieces 3 and 28 is formed. A condenser 4 and a rotary plate 25 are disposed in the drain pan 29, and the drain water dripped from the evaporator 13 is guided through the drain receiver 14, the drain guide 15, and the fins 18 of the condenser 4. . Before most of the drain water from the evaporator 13 flows into the drain pan,
Although the drain water is heated and evaporated by the heat of the condenser 4, the drain water that is not completely evaporated is received by the drain pan 29 of the bottom plate 27. In this way, drain pan 2
When drain water accumulates in the drain 9, it is scraped up by the rotation of the rotary plate 25 and sprayed onto the condenser 4.

Figure 5 shows the main parts of the heat exchange chamber 11.
0 is a notch formed in the front corner of the substantially triangular horizontal partition plate 10, and an opening 31 is provided on the side. This notch 30 has a protrusion 32 extending forward.
The width a of the opening 31 is set smaller than the width b of the notch 30. Reference numerals 33 and 34 indicate refrigerant pipes extending laterally from the left side of the evaporator 13 and hanging downward. Both of the refrigerant pipes 33 and 34 are led along the drain pan 29 on the bottom plate, and one refrigerant pipe 33 is connected to the suction pipe 39 of the compressor 23, and the other refrigerant pipe 34 is connected to the suction pipe 39 of the compressor 23.
is connected to a condenser 4 (see Figure 2). still,
In FIG. 2, numeral 38 is a discharge pipe of the compressor 23 connected to the condenser 4. 35 is this refrigerant pipe 3
This is a heat insulating material that covers the outer periphery of parts 3 and 34. The refrigerant pipes 33 and 34 covered with the heat insulating material 35 are housed in the cutout 30 in the front-rear direction of the air conditioner 1.

36 is a front panel in which the suction port 21 and the discharge port 22 are formed, and the heat exchange chamber 11 and the machine room 12
It covers the front from the front. This front panel 36 is fixed to the exterior body 6.

When assembling such an integrated air conditioner, first the compressor 23, the partition plate 2, the condenser 4, and the cross flow fan 5 on the outdoor side are placed on the bottom plate. Next, a horizontal partition plate is fixed to the partition plate, and the evaporator 13 and the indoor cross flow fan 19 are placed on this partition plate 10. After fixing each part in this way, the suction side pipe 39 of the compressor 23 and the refrigerant pipe 33 extending from the evaporator 13 are installed on the side of the notch 30.
are pulled out and welded together, and then a heat insulating material 35 is wrapped around the connected refrigerant pipe, and the refrigerant pipe is housed in the notch 30 through the opening 31 of the notch 30. At this time, the two refrigerant pipes 33 and 34 covered with the heat insulating material 35 are tightly housed within the cutout 30, making it difficult for the pipes 33 and 34 to come out through the opening 31 of the cutout 30. Then, the front panel 36 is attached to the exterior body 6, and the inner surface 37 of this panel 36 closes the opening of the notch.

Furthermore, if the refrigerant pipes connected to the compressor 23 and evaporator 13 are pulled out from the opening 31 of the notch 30 of the horizontal partition plate 10, the refrigerant pipes connected to the refrigeration equipment can be removed from the casing 9 and the horizontal partition plate 10. Service inspections can be performed.

(g) Effect of the invention As described above, according to the invention, the front indoor chamber of the fuselage body is divided into a heat exchange room and a machine room by a horizontal partition plate, and a notch is provided on the front side of this horizontal partition plate. The refrigerant pipe is housed in this notch, and the opening of this notch is covered with a panel that can be attached to the exterior body.Remove the panel from the exterior body.
By pulling out the refrigerant pipe through the opening of the notch, it is possible to easily service and inspect the parts built into the aircraft while the refrigerant pipe remains connected to refrigeration equipment such as the heat exchanger and compressor.
