Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an outdoor unit of an air conditioner.

[Technical background of the invention and its problems] Conventionally, outdoor units for split-type air conditioners have been used with a smaller installation space per unit, as shown in Figures 6 and 7. ing.

Specifically, a machine room b is provided on one longitudinal side of the unit main body a of the outdoor unit, and an L-shaped outdoor heat exchanger c is installed along the vertical direction on the circumferential side of the other side. A suction port is provided around the outside heat exchanger c, and an air outlet d is provided on the front surface of the unit body a facing the outdoor heat exchanger c, and an air blower e is provided inside the air outlet d. A structure was used to reduce the installation area of a.

However, although it is true that these outdoor units require a small installation space when installed alone, they draw in air from the rear and blow out air from the front, so if you try to install multiple units side by side in a concentrated manner,
As shown in Fig. 8, in addition to the service space t, the space u necessary for blowing out, and the space v necessary for suction, there is space between each adjacent outdoor unit.
An extra space w must be provided to prevent the heat-exchanged winds from interfering with each other. Therefore, when installing in a concentrated manner, the actual installation space (A distance x
There was a drawback that the distance B) became large.

[Purpose of the invention] This invention was made with a focus on these problems, and its purpose is to create an air conditioner that allows multiple units to be installed centrally in a small amount of actual installation space. Our objective is to provide an outdoor unit for the machine.

[Structure and operation of the device] This device has a box-shaped unit body whose depth and height are longer than the width;
An air outlet formed on the upper surface of the unit body,
a ventilation passage formed in the unit main body, the upper part of which communicates with the air outlet; and a blower installed in the upper part of the ventilation passage in the unit main body, facing the air outlet;
An outdoor heat exchanger is installed in the middle part of the ventilation passage, which is higher than the floor by a predetermined dimension inside the unit body, to block this ventilation passage in the vertical direction and to have a V-shaped cross section in the depth direction. At one end in the depth direction, there is a ventilation passage that accommodates the outdoor heat exchanger, and a machine room that accommodates the compressor, electrical parts box, etc., which is divided into front and back sections via a partition plate, and the depth of the unit body. A suction port that communicates with the ventilation passage on the air suction side of the outdoor heat exchanger, which is formed on both the left and right sides of the unit and the lower part of the side opposite to the unit main body where the machine room is installed, is provided. The reason lies in the configuration of the outdoor unit of the harmonizer.

As a result, when installing multiple indoor units in a concentrated manner, the machine room can be lined up in the same position.
A plurality of outdoor units can be installed in succession in the width direction so that the unit bodies are in close contact with each other, eliminating the space between the units. Moreover, since the outdoor unit body is box-shaped with a larger depth and height than width, the overall width can be kept small even when multiple units are installed in parallel in the width direction, allowing for compact installation. becomes possible. Furthermore, by installing them side by side, the machine rooms of each unit are lined up horizontally in the same position, so electrical wiring to the machine room of each outdoor unit, piping connections with the indoor unit, etc. can be done in line with the arrangement. It is only necessary to carry out the construction work, and the work required for installation can be done rationally, making the installation work easier. Moreover,
Maintenance work after installation can be performed efficiently. In addition, the outdoor heat exchanger has air suction ports formed on both left and right sides in the depth direction of the unit main body, and in the lower part of the side opposite to the unit main body where the machine room is installed. Since air is taken in from the suction port that communicates with the side ventilation passages, a sufficient amount of air intake can be secured in the ventilation passages of each indoor unit even when they are installed side by side.

[Embodiment of the invention] The invention will be described below based on an embodiment shown in FIGS. 1 to 5. Fig. 1 shows the whole outdoor unit to which this invention is applied, Fig. 2 shows a side view of the outdoor unit, and Fig. 3 shows a rear sectional view of the outdoor unit on the ventilation path side. 1 is a box-shaped unit body, and this box-shaped unit body 1 has a shape in which the depth and height dimensions are longer than the width dimension. Inside the unit main body 1, two spaces are formed in the front and back when viewed from the depth direction by a partition plate 2, of which a space on one side end (hereinafter referred to as the front) is configured as a machine room 3.

Inside this machine room 3, there is a compressor 4, an electrical parts box 5,
Equipment such as a four-way valve 6 is housed. In addition, on the upper surface of the unit main body 1, there are two air outlets 7, 7.
is provided.

On the other hand, on both left and right sides of the unit body 1, which correspond to the other partitioned space on the depth direction adjacent to the machine room 3 (hereinafter referred to as side surfaces), there are openings extending from the middle part to the bottom part. Suction ports 8a and 8a (first suction ports) are provided, respectively. Further, a suction port 8b (second suction port) forming an opening is also provided at the lower stage of the side surface (hereinafter referred to as the back surface) opposite to the unit main body where the machine room is installed.

In this way, inside the unit main body, the machine room 3
The suction ports 8a, 8a, 8a, 8a, 8b, 8b, 8a, 8a, 8a, 8a, 8b, 8a, 8b, 8a, 8a, 8b, 8a,
8b, and a ventilation passage 9 that communicates with the air outlet 7 formed on the upper surface of the unit main body 1, respectively.

This ventilation passage 9 includes a V-shaped outdoor heat exchanger 10.
is provided. This outdoor heat exchanger 10 is
It is constructed by assembling two flat air heat exchangers into a V-shape. This outdoor heat exchanger has each end arranged in the middle part of the ventilation passage, which is a certain dimension higher than the floor surface inside the unit main body, so that the ventilation passage is blocked in the vertical direction and has a V-shaped cross section in the depth direction. It is attached so as to come into contact with the back side plate surface portion which is the upper stage of the opening 8b and the plate surface portion of the partition plate 2 facing thereto. Thereby, the outdoor heat exchanger is configured such that each suction port 8a, 8a, 8b communicates with the ventilation path 9 on the air suction side, and the air outlet 7 communicates with the ventilation path 9 on the air blowout side. It is configured like this. That is, the outdoor heat exchanger 10 is designed to exchange heat with the outside air sucked in through the suction ports 8a, 8a and the outside air sucked in through the suction port 8b.
Note that the upper end of the outdoor heat exchanger 10 is connected to each suction port 8.
The upper ends of a and 8a are tightly joined to the side plates of the unit main body 1, and both ends are closely joined to the partition plate 2 and the back plate of the unit main body 1, so that the air sucked in passes through the heat exchanger. The structure is such that it is guided upward through the tube.

In addition, for example, a propeller fan 11 is provided in the ventilation passage 9 between the outlet ports 7 and the outdoor heat exchanger 10.
A blower 11 is provided in which a fan motor 11b is connected to a rotating shaft of a fan motor 11b. Thereby, outside air is forcibly taken into the ventilation path 9, and the outside air is applied to the outdoor heat exchanger 10.

On the other hand, a drain pan 12 for receiving drain water generated in the outdoor heat exchanger 10 is provided in the longitudinal direction of the outdoor heat exchanger 10 directly below the close contact portion constituting the lower end of the outdoor heat exchanger 10. It is being Also,
An L-shaped drain pipe 13 is rotatably connected to the lower surface of the drain tray 12 placed at a high position, and even with the difference in head caused by the height of the bottom floor of the unit main body 1, The structure allows drain water to be discharged to any horizontal position. Although not shown, the drain plate 12 is slightly inclined so that drain water is guided toward the drain pipe 13 side.

With this structure, an outdoor unit with a small installation space per unit is constructed.

Therefore, the outdoor unit configured as described above operates by operating the blowers 11, 11.
Outside air is inlet 8a, 8 from the bottom of the unit body 1.
It is sucked in through a and 8b. This air flows through the flow path 9 while passing through the outdoor heat exchanger 10 and exchanges heat with the outdoor heat exchanger 10. Then, the air after heat exchange is blown out from the air outlet 7 to the upper side of the unit main body 1.

Therefore, when installing a plurality of outdoor units in a concentrated manner, as shown in FIGS. Installation is carried out by bringing the sides of one side close together and connecting them in the width direction.

When a plurality of outdoor units are installed in this manner, there is no need for any space required in the past to prevent mutual interference of wind between the unit bodies.

In other words, as shown in Figure 5, the installation space is much smaller than the conventional one, which is just the size of the unit body 1, the space v required for suction on both sides, and the service space t. (C distance x D distance) is enough.

Therefore, multiple outdoor units can be installed centrally in a small amount of actual installation space.

Moreover, since the machine rooms 3 of each outdoor unit are lined up horizontally in the same position, the machine rooms 3 of each outdoor unit
The electrical wiring, piping connections, etc. for ... can be carried out according to the arrangement, and the work necessary for installation can be carried out rationally. In other words, the work when installing the outdoor unit is easy.

Also, normally, when multiple outdoor units are installed, maintenance in the machine room 3 tends to be troublesome, but when the outdoor units are installed as described above, each machine room 3... It is easy to maintain because it is lined up in the same way.

In addition, drain piping becomes easier. That is, by adopting a structure in which a drain plate 12 is provided at the lower part of the outdoor heat exchanger 10 and a rotatable drain pipe 13 is provided in the drain plate 12, for example, as shown in FIG. By installing one drain header pipe 14 in the drain pipe, and connecting each drain pipe 13 of the outdoor unit to the header pipe 14 by determining the direction, there is no need for extra piping for intensive installation of the outdoor unit. Drain water can be concentrated and drained even when plumbing work is not required. In particular, in a normal outdoor unit, the bottom floor of the unit body 1 also serves as a drain pan, making it difficult to secure the head needed to drain the drain water. A drain pan 12 is provided in the lower space of the outdoor heat exchanger 10 (between the outdoor heat exchanger 10 and the bottom floor of the unit main body 1), and the drain pan 12 is set at a high position, making it easy to Moreover, a sufficient head difference can be obtained. For this reason, piping work is simple and drainage is extremely good.

[Effects of the invention] As explained above, according to this invention, when multiple indoor units are installed in a concentrated manner, the multiple outdoor units are placed next to each other in the width direction so that the machine rooms are lined up in the same position. The units can be installed side by side in close proximity, eliminating the space between units. In addition, since the outdoor unit body is box-shaped with a larger depth and height than width, the overall width can be kept small even when multiple units are installed in parallel in the width direction. Compact installation is possible. Furthermore, by installing them side by side, the machine rooms of each unit are lined up horizontally in the same position, so electrical wiring to the machine room of each outdoor unit, piping connections with the indoor unit, etc. can be done in line with the arrangement. All you have to do is carry out the construction work, and the work necessary for installation can be done rationally.
Installation work becomes easier. Moreover, maintenance work after installation can be performed efficiently. In addition, the outdoor heat exchanger has air suction ports formed on both left and right sides in the depth direction of the unit main body, and in the lower part of the side opposite to the unit main body where the machine room is installed. Since air is taken in from the suction port communicating with the side ventilation path, the effect is that even if the indoor units are installed side by side, a sufficient amount of intake air can be ensured through the ventilation path of each indoor unit.
