Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to the configuration of an outdoor unit in a remote condenser type separate air conditioner.

Conventional configuration and its problems Conventionally, it was a remote condenser air conditioner with a compressor and an indoor heat exchanger installed on the indoor unit side and an outdoor heat exchanger installed on the outdoor unit side. The configuration is shown in FIGS. 1 and 2. Reference numeral 1 in FIG. 1 is the main body of the outdoor unit, in which suction ports 2 are provided on both sides, an air outlet 3 is provided on the top side, and a blower 4 is provided in the air outlet 3. In the main body 1, there are 3 heat exchangers 5 and 6 necessary to produce the required capacity.
By operating the blower 4, the air flowing in from the suction port 2 passes through each heat exchanger 5, 6, and is blown out from the air outlet 3. I have to.

By the way, in this example, the heat exchange efficiency is good because the heat exchangers 5 and 6 are arranged in a V shape, but
Since a large floor area is required and the V-shape is used, the spaces 7, 8, and 9 become large, and therefore the product becomes large, and must be made that much larger.

In order to eliminate these drawbacks, an outdoor unit having the configuration shown in FIG. 2 has been considered. That is, the main body 10 of the outdoor unit is configured vertically, and an inlet 11 is provided on one side and an outlet 12 is provided on the other side.
By configuring the heat exchanger 13 configured in rows and stages and a plurality of blowers 14 and 15,
There is a device that is miniaturized without requiring a large floor area or creating a space within the main body 10.

However, in this case, the heat exchanger 13
For example, because it is constructed in one piece in a vertically long manner,
For 4 horsepower class or higher, heat exchanger 13
The total area of the base section 16 becomes large, making it difficult to work manually.
In order to place the heat exchanger 13 on the top plate 1 or to hold the heat exchanger 13 with the holder 17 at the top after placing it on the top plate 1.
8 and the holder 17 and the work of holding the heat exchanger 13 was also difficult.

Purpose of the invention The present invention solves the above-mentioned drawbacks of the conventional heat exchanger, and aims to construct a vertically elongated heat exchanger and facilitate assembly work.

Structure of the invention In order to achieve the above object, the invention includes an upper heat exchanger and a lower heat exchanger provided facing the suction port of the outdoor unit body, and a combination of the lower heat exchanger and the upper heat exchanger. A holder is provided between the holder and has a guide rail and has an H-shaped cross section. If you are in a class higher than
The vertically long heat exchanger is divided into parts to reduce assembly man-hours.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In the figure, reference numeral 21 denotes an outdoor unit main body that is vertically long and thin in depth, and has a suction port 22 on the back side and an air outlet 23 on the front side. In the outdoor unit main body 21, the suction port 22
A lower heat exchanger 24 is provided facing the lower heat exchanger 24, and its refrigerant pipes 24a are provided in three rows and multiple stages. Further, an upper heat exchanger 25 is provided in a vertical manner facing the suction port 22 and above the lower heat exchanger 24 via a holder 26, and its refrigerant pipes 25a are provided in three rows and multiple stages. . The holder 26 has an H-shaped cross section and consists of guide rails 27 and 28 and a receiving plate 29. In addition, the upper and lower heat exchangers 24, 2
Holders 26 are attached to the side plates 30, 31, 32, 33 of 5.
Screw holes 34, 35 and 36, 37 corresponding to the holes 38 to 41 are provided. 42 in the figure is a U vent.

The lower heat exchanger 24 has both ends attached to the base portion 4.
3, and the base part 43
is provided at the inner bottom of the outdoor unit main body 21.
Further, the upper heat exchanger 25 is held down by an upper holder 44, and fixing pieces 46 on both sides of the upper holder 44 are fixed to the top plate 45 by welding or the like. The upper holder 44 also has a holding portion 47 that is fitted over the width of the upper heat exchanger. The width A of the receiving plate 29 of the holder 26 is made slightly larger than the width B of the lower heat exchanger 24 and the upper heat exchanger 25 so that they fit together, and the width C of the holding part 47 of the upper holder 44 is The width is also the same as the width A. Reference numerals 48 and 49 in the figure designate a plurality of blowers facing the air outlet 23.

In the above configuration, when assembling, the lower heat exchanger 24 is placed on the base portion 43. next,
The holder 26 is placed on the lower heat exchanger 24. At this time, the width A fits into the width B of the lower heat exchanger, and by the guide rails 27 and 28,
The upper part of the lower heat exchanger 24 is guided on the side, and the hole 38 is connected to the screw hole 34 and also to the hole 39.
is aligned with the screw hole 35 and fixed with a screw. Next, the upper heat exchanger 25 is placed on the receiving plate 29 so as to be fitted thereon, so that the lower side of the upper heat exchanger 25 is guided, and
Hole 40 and screw hole 36, and hole 41 and screw hole 3
7 are aligned and fixed with screws. Above the upper heat exchanger, the upper part of the upper heat exchanger is fitted and held within the width C of the upper holder 44. Note that the upper holder 44 is fitted into the top plate 45 in a fixed state.

Effects of the invention As is clear from the description of the above embodiments, the present invention has an upper heat exchanger and a lower heat exchanger provided facing the suction port of the outdoor unit body, and a combination of the upper and lower heat exchangers. A holder having a guide rail therebetween and having an H-shaped cross section is provided, in the holder,
The side plates of the upper and lower heat exchangers and the guide rail of the holder are fixed with screws, and the upper heat exchanger is held by the upper holder to form a vertically elongated heat exchanger. Therefore, even in the case of medium-sized or large-sized heat exchangers, the lower heat exchanger, holder, and upper heat exchanger are assembled in an orderly manner, making the assembly process safe and easy. The man-hours are less than the difficulty of assembling a large, one-piece heat exchanger.

In addition, when exporting such an outdoor unit (air conditioner) as a knocked-down type product (local assembly for export of semi-finished product), it is completed by local assembly, but
Even in this case, a machine such as a crane required for assembly is not required, and assembly is easy, which is advantageous.
