Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an attic air conditioner that performs air conditioning using the attic of a residence, and is particularly applicable as an air conditioner for a residence.

[Background technology]

BACKGROUND ART Conventionally, heat pump type air conditioner devices that circulate refrigerant between an outdoor unit and an indoor unit have been widely used for heating and cooling each room in a house. In such air conditioner systems, it is common to have a pair of outdoor and indoor units in each room, and these indoor units are ceiling-hanging, wall-mounting, floor-standing, etc. placed indoors.

[Problem to be solved by the invention]

However, since the indoor unit of the conventional air conditioner is installed on the wall or ceiling of the room, the number of design elements in the room increases, making the room cluttered and spoiling the appearance of the room. In particular, in industrialized housing, because the housing units are manufactured in factories, it is possible to have uniform interior colors, etc., but air conditioning equipment is often procured separately, and it is possible to unify the interior colors by arranging indoor units. Sometimes the space was disturbed.

In addition, since the indoor unit of an air conditioner is installed at a predetermined location indoors, when heating or cooling, the air conditioning efficiency in the area around the indoor unit is high, but the air conditioning efficiency in areas far away from the indoor unit is low, and the There was a problem in that the temperature distribution was uneven.

Furthermore, an air conditioner sucks indoor air in the indoor unit, performs air conditioning such as cooling or heating, and sends it into the room, but since there is a lot of conditioned air around the indoor unit, There is a problem that air conditioning is performed by re-inhaling already conditioned air, making it impossible to improve the thermal efficiency of the indoor unit.

An object of the present invention is to provide an attic air conditioner that can improve the appearance of a room, as well as improve air conditioning efficiency and thermal efficiency.

[Means to solve the problem]

The attic air conditioner of the present invention partitions the attic space of a house into an intake space and an exhaust space using a partition member, and communicates the intake space and the exhaust space with the interior of the room through an intake port and an exhaust port, respectively. The present invention is characterized in that an indoor unit of an air conditioner for conditioning air in the intake space and sending it to the exhaust space is provided in the partition member.

Here, it is sufficient that at least one indoor unit of the air conditioner is installed in the partition member part of the attic space.

[Effect]

In the present invention, since the indoor unit of the air conditioner is placed in the space behind the ceiling and not inside the room, the number of design elements in the room can be reduced and the appearance of the room can be improved.

In addition, since we have created an exhaust space behind the ceiling, it is possible to blow out the air conditioned by the indoor unit into the room from various points on the ceiling, making the indoor temperature distribution uniform and greatly improving air conditioning efficiency. .

Furthermore, since the air intake space is provided in the ceiling, indoor air can be evenly drawn in from various locations on the ceiling, improving the thermal efficiency of the indoor unit.

In addition, the air intake space and exhaust space use the space under the ceiling and can be made relatively large in volume, so pressure fluctuations during intake or exhaust are reduced, allowing steady air circulation. The air conditioning can be performed accurately and reliably, and even if the indoor unit is not directly installed in the room, air conditioning can be performed reliably, thereby achieving the above object.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, a partition plate 5 is provided in an attic space 4 divided by a ceiling 2 on the first floor and a floor 3 on the second floor of a house.

The partition plate 5 is arranged so as to have a substantially square plane as shown in FIG. 2, and the space surrounded by the partition plate 5 in the attic space 4 forms an air intake space IO.

Further, an exhaust space 2 is formed by a space arranged around this intake space 10 and surrounded by the partition plate 5 and the wall 6 of the house.
0 is formed.

A step 11 is provided on the ceiling 2, which is the bottom surface of the air intake space 10, approximately along the partition plate 5.
As shown in FIG. 1, an air intake port 12 that communicates the indoor room 7 with the air intake space 10 is provided over substantially the entire circumference of the step 11.

On the other hand, as shown in FIG. 2, an exhaust port 21 is provided in the ceiling 2, which is the bottom surface of the exhaust space 20, so as to have a substantially square shape along the wall 6. Above the exhaust port 21, there is a baffle plate 22 along the exhaust port 21, as shown in FIG.
is located.

On the exhaust space 20 side of the partition plate 5, two indoor units 30 of the air conditioner are provided at positions facing each other. As shown in FIG. 3, an opening 8 is provided in the partition plate 5 at a portion where the indoor unit 30 can be placed.
The intake space IO and the exhaust space 20 can communicate with each other through the opening 8 and the indoor unit 30.

The indoor unit 30 is equipped with a coil, a fan, etc. like a normal indoor unit such as an air conditioner, and is connected to an outdoor unit 32 equipped with a condenser, a compressor, etc. via a refrigerant pipe 31 as shown in FIG. It is connected.

In this embodiment with such a configuration, when the indoor unit 30 and the outdoor unit 32 are operated, the air in the room 7 flows through the intake port 1.
2 and is once sucked into the intake space IO. This air is mixed and made uniform within the intake space IO, and is further sent to the indoor unit 30 via the opening 8.

The indoor unit 30 appropriately performs air conditioning such as cooling, heating, dehumidification, and humidification of the air, and sends this conditioned air to the exhaust space 2.
Send to 0.

This conditioned air is made uniform in the exhaust space 20 by colliding with the baffle plate 22, and is blown out into the room 7 from the exhaust port 21.

According to this embodiment with such a configuration, since the indoor unit 30 of the air conditioner is arranged in the attic space 4, there is no need to arrange the indoor unit 30 in the room 7, and the design elements of the room 7 can be reduced. can improve the appearance.

In particular, even in a house such as an industrialized house where the interior 7 has a uniform color etc., the indoor unit 30 can be placed without disturbing the unified space.

Further, an air intake space 10 is formed in the attic space 4, and an air intake port 12 that communicates this air intake space 10 with the indoor room 7 is provided in the ceiling 2.
Since the indoor unit 30 is arranged in a substantially square shape, the indoor unit 30 is placed in the indoor unit 7.
Air can be evenly inhaled from a wide range of spaces. Therefore, the thermal efficiency of the indoor unit 30 can be improved compared to a conventional air conditioner that sucks in air around the indoor unit to condition it.

Furthermore, since the air from the room 7 is not directly supplied to the indoor unit 30, but is once stored in the intake space IO before being supplied, pressure fluctuations in the air sent to the indoor unit 30 can be reduced. Therefore, without being affected by pressure fluctuations in the room 7,
Air circulation can be performed regularly and reliably, and air conditioning by the indoor unit 30 can also be performed reliably.

Further, the air conditioned by the indoor unit 30 is first made uniform in the exhaust space 20 and then blown out into the room 7 from the exhaust port 21, and the exhaust port 21 is arranged along the wall 6 almost all around the ceiling 2. Since the air conditioner is provided over the entire room 7, conditioned air can be evenly supplied to the entire room 7, and the temperature distribution in the room can be made uniform, thereby improving air conditioning efficiency.

It should be noted that the present invention is not limited to the configurations of the embodiments described above, and any modifications within the range that can achieve the object of the present invention are included in the present invention.

For example, in the above embodiment, the intake space 10 was formed at the center of the attic space 4, and the exhaust space 20 was formed at the wall 6, but as shown in FIG. An exhaust space 20 may be formed on the wall 6 side, and an intake space 10 may be formed on the wall 6 side, and these may be set as appropriate depending on the switching between cooling and heating, the shape of the location where the indoor unit 30, etc. are arranged, etc. .

Further, in the above embodiment, the attic space 4 was divided into two spaces by the partition plate 5, but as shown in FIG. 4(B), another partition plate 5A is provided inside the partition plate 5. divided into three spaces 41, 42, and 43, and two of these
Two spaces may be used as an intake space and an exhaust space. In this case, if the spaces 41° 43 are used, the indoor unit 30 may be placed in the space 42, and in other cases, the partition plates 5, 5 that separate the intake spaces and the exhaust spaces may be used.
The indoor unit 30 may be placed in the part A.

Furthermore, as shown in FIG. 4(C), spaces 44 and 45 divided into a C-shape and a T-shape in plan by the partition plate 5 may be used as the intake space and the exhaust space. As shown in FIG. 4(D), spaces 46 and 47 alternately arranged in a comb-like manner by the partition plate 5 may be used as an intake space and an exhaust space.

In short, in the present invention, an air intake space and an exhaust space may be provided in the attic space 4, and the shape and size thereof may be appropriately set in implementation.

Further, the partition member of the present invention is not limited to the partition plate 5, and may be any member that can partition the attic space 4 into at least two spaces.

Furthermore, although two indoor units 30 were provided in the embodiment, one or three or more indoor units may be used, and the number may be set as appropriate in consideration of the size of the room in which the present invention is used.
