Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air source heat pump unit that is inserted into a building wall to replace a part of the exterior wall material, and is particularly improved so that its installation work and maintenance work can be simplified, and that it can withstand rain, snow, etc. This article relates to a wall-mounted air conditioner that has been improved so that it is not affected by such factors.

Conventionally, attempts have been made to cut out a part of the building exterior material and insert the air conditioner main body to reduce the installation area of the air conditioner and effectively utilize the perimeter zone.
There are those described in Japanese Patent No. 9847 and US Pat. No. 3,366,169.

However, the method described in JP-A No. 50-49847 requires a large area for the air conditioner because the indoor unit and the outdoor unit are placed side by side along the wall surface, and the outdoor unit is located indoors. In the unit part, the air supply/intake port cannot be formed, so the dead space becomes large, and since air cannot be supplied from the entire length of the air conditioner, the desired airflow pattern cannot be obtained.

On the other hand, a unit in which the indoor unit part and the outdoor unit part are integrally constructed with the front and back sides facing each other is very advantageous since it does not have the above-mentioned drawbacks.

In this case, especially in a method in which the outdoor unit part is inserted into the building wall thickness, it is possible to effectively utilize the wall thickness space and reduce the area occupied indoors, and since only the indoor unit part protrudes indoors, the wall surface It has the advantage of being able to form a continuous air supply outlet along the

There is an air conditioner similar to the latter method, as typified by the aforementioned U.S. Pat. This has the disadvantage that the internal equipment will corrode due to the intrusion of rain, snow, etc., and since it is fitted into the building wall to be airtight with the outside, it is difficult to install and maintain it, and therefore the installation location is difficult. In many cases, installation of this air conditioner has to be abandoned depending on the type of building or building, and the air conditioner cannot be a practical and versatile air conditioner.

The present invention has devised an air conditioner that does not have such drawbacks, and is a compact air heat source that has an improved internal structure so that it is not affected by rain, snow, etc., and that is easy to install, inspect, and repair. It provides a heat pump unit.

Explaining based on the embodiment of the present invention shown in the accompanying drawings, the main structure of the unit of the present invention is as shown in FIG. Consisting of an air heat source heat pump unit that is housed together in one casing and configured as a single unit, at least a part of the outdoor unit part B is inserted into the building wall thickness to connect the outside surface of the building wall and the outside surface of the outdoor unit. The unit body is flange-bonded to the building wall at a position where the unit B is substantially aligned (as shown in Figures 3 and 4), and the exhaust blowing chamber 2 is installed above the outdoor unit B and inside the outside of the building wall.
The outdoor blower 3 is installed in such a way that the exhaust port 4 of the outdoor blower 3 protrudes from below within the exhaust blowing chamber 2.
It is characterized by having been placed.

As mentioned above, in FIG. 1, the indoor unit part A has a return air intake 5 at the bottom and a supply air outlet 6 at the top to provide an upward flow of processed air. The inner heat exchanger 8 is arranged obliquely.

On the other hand, in the outdoor unit part B, an outdoor heat exchanger 9 is disposed below one outdoor fan 3, and the heat source air flow is processed upward from the outside air intake port 10 toward the exhaust chamber 2. .

The drain of the indoor heat exchanger 8 is connected to the drain pipe 12 from the indoor drain pan 11 to the drain pan 11' of the outdoor heat exchanger 9.
and is discharged from the drain 12'.

At that time, the piping 12 is guided to the upper surface of the outdoor heat exchanger 9, and the condensate generated in the indoor heat exchanger 8 during cooling is dripped onto the surface of the outdoor heat exchanger 9 to partially evaporate and the heated condensate. It is possible to adopt a structure in which the water is received in the drain pan 11' and is discharged.

In this way, the inner unit part A and the outdoor unit part B are housed back to back in the casing 6 with the partition wall 1 interposed between them. An airtight connection can be easily achieved by screwing the attached flange 13 to the frame of the building wall.

One of the features of the air conditioner of the present invention is that the air conditioner of the present invention is constructed in such a way that each member can be disassembled to facilitate inspection and repair of each component. Explain according to the following.

Fig. 2 shows an exploded view when installing the air conditioner of the present invention to a part of the perimeter of the waist area below the window in an office, etc., and shows the penetration where the outdoor unit part B of this unit fits into the wall 14 of the waist area below the window. A hole is formed, a frame 15 is attached to the periphery of the hole on the indoor side, and a louver 16 is attached as necessary.

The flange 13 of the unit body is attached to this frame 15, and the wall 14
The outdoor unit t-B is joined and fixed at a position where the outer surface of the outdoor unit t-B substantially matches the outer surface of the outdoor unit t-B (the position of the louver 16), and can support the weight of the unit main body.

On the other hand, the casing 6 (Fig. 1) includes a front wall 16, a top plate 1
7, side plate 18, bottom frame 19, filter 20, grill 21
etc. are all removably assembled, and the control box 22 is also independently removable and can be easily replaced with spare parts.

The compressor, accumulator, and other refrigerant equipment are housed in a box 23, and this box 23 can also be opened and closed, making it easy to inspect and repair the refrigerant area.

FIGS. 3 and 4 show cross-sections of the unit installed on the wall 14 below the window.

Fig. 3 shows the case where it is attached to an ordinary concrete wall 14, and Fig. 4 shows the case where it is cleverly attached to a curtain wall part 24 which has become widely used in buildings etc. these days.

When attached to the curtain wall section 24, the double wall space 25 can be used as an outside air intake, completely preventing rain, snow, etc. accompanying the outside air from entering the cabin, and there is no problem such as direct sunlight. Therefore, it is extremely beneficial.

As shown in FIG. 1.3.4, a horizontal exhaust blowing chamber 2 is provided above the outdoor unit B and inside the building wall 14.

A plate 26 (
The outdoor side blower 3 is arranged upward so that the exhaust port 4 of the outdoor side blower 3 protrudes from the outside (FIG. 1).

This configuration prevents the exhaust hole from opening directly to the outside air, and even if rain or snow enters the exhaust chamber 2, it is prevented from entering the interior of the machine.

While the unit is in operation, rain and snow are blown away by the exhaust gas, so they rarely enter the exhaust chamber 2.

As described above, the air source heat pump unit of the present invention effectively utilizes a portion of the verimeter in the lower ring of the window to reduce the occupied area, and has a structure that can replace a portion of the outer wall to reduce the effects of rain and snow. We have succeeded in virtually eliminating this problem, and it can be used for general purposes as an air conditioner that serves as a part of the perimeter.

It also facilitates construction and maintenance work, and has extremely high practical value.
