Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling air conditioner for uniformly blowing out conditioned air from a large area of a ceiling portion and radiating radiant heat from the ceiling portion for air conditioning the room.

[0002]

2. Description of the Related Art A conventional ceiling air conditioner of this type is disclosed in Japanese Utility Model Publication No. 5-26413. As shown in FIG. 7, a calcium silicate-based artificial wood is attached to the lower surface of an air conditioning chamber 1 to which conditioned air is supplied to form a ceiling portion 2 ', and a peripheral portion of the ceiling portion 2'is formed. A large number of blow-out holes 3 are bored to form a breathable ceiling portion 4 ', and the remaining surface is a heat radiation portion 5'for radiating heat. In such a ceiling air conditioner, conditioned air is blown out from the blow-out hole 3 of the breathable ceiling part 4'and heat is radiated from the heat radiating part 5'for air conditioning the room.

[0003]

In the case of the above-mentioned conventional example, the air-conditioning air can be blown out and the air can be conditioned by heat radiation. However, the air-permeable ceiling portion 4'has a large number of blow-out holes 3 formed therein. However, there is a problem in that the blow-out holes 3 are visible and the appearance of the ceiling is deteriorated, and there is a problem in that air containing dust or the like is blown out because the air is blown out from the blow-out holes 3. , And the heat radiation part 5 '
Since it is made of calcium silicate-based artificial wood, it has poor thermal conductivity and has a problem that the efficiency of transmitting heat by heat radiation to the room is poor.

The present invention has been made in view of the above problems, and an object of the present invention is to improve the appearance without exposing holes in the ceiling and to purify conditioned air. (EN) It is possible to provide a ceiling air conditioner that can be blown out and can radiate heat more efficiently.

[0005]

In order to achieve the above object, the ceiling air conditioner of the present invention has an air conditioning chamber 1 to which conditioned air is supplied arranged behind the ceiling, and a ceiling portion 2 below the air conditioning chamber 1 is breathable. The heat radiation part 5 is composed of the ceiling part 4 and the heat radiating part 5, and the air permeable ceiling part 4 is made of a breathable ceiling material having a number of minute vent holes which cannot be discerned by eyes and also has a filter function. It is characterized by being formed from a heat radiation ceiling material having good conductivity.

It is also preferable that the air-permeable ceiling portion 4 is provided so as to surround the heat radiation portion 5.

[0007]

According to the above construction, the conditioned air can be blown out from the breathable ceiling part 4 and the heat can be radiated from the heat radiating part 5 to perform the air conditioning. At this time, since the breathable ceiling part 4 is formed by providing innumerable vent holes which cannot be discerned with eyes, the appearance can be improved without the presence of a large number of visible holes in the ceiling part as in the conventional case. Since the breathable ceiling part 4 has a filter function, air can be purified and blown out, and the heat radiation part 5 is formed of a heat radiation ceiling material having good heat conductivity, so that the heat radiation efficiency is high. Can be improved.

Further, if the breathable ceiling portion 4 is provided so as to surround the heat radiating portion 5, conditioned air is blown from the surroundings to obtain ideal convection, and it is easy to provide a lighting fixture or the like in the center. Can be provided.

[Embodiment] In the case of the present embodiment, it is constructed in a one-room apartment or a hotel room. As shown in FIG. 3, a passage 8 is provided from the door 6 to the living room 7, and next to the passage 8, a sanitary room 9 such as a bathroom and a toilet is provided. Desk 10 and bed 1 in living room 7
1 is provided. A ceiling portion 2 is formed below the ceiling slab 12 by pasting a ceiling plate through a ceiling back space 13 having a predetermined height.

As shown in FIG. 1, an air conditioning chamber 1 is arranged in a space 13 above the ceiling above the living room 7, and the lower surface opening of the air conditioning chamber 1 is flush with the ceiling portion 2. The air conditioning chamber 1 is slightly smaller than the size of the living room 7. Ceiling part 2 on the lower surface of this air conditioning chamber 1
As shown in FIG. 2, an air-permeable ceiling part 4 and a heat radiating part 5 are formed therein. In the case of the present embodiment, the breathable ceiling portion 4 is provided in the shape of a square ring around the periphery, and the heat radiation portion 5 is provided so as to be surrounded by the breathable ceiling portion 4. The breathable ceiling part 4 is formed by sticking a breathable ceiling material, and this breathable ceiling material has countless fine ventilation holes (invisible holes) that cannot be visually recognized and has a filter function. Specifically, there are cloth materials, paper materials, felts, non-woven fabrics, rock wool materials, filter materials and the like. The heat radiation part 5 is formed by pasting a heat radiation ceiling material, and the heat radiation ceiling material is made of a material having good thermal conductivity, and is formed of, for example, an aluminum radiation panel. A normal ceiling material is stuck on the entire surface of the ceiling 2 other than the ceiling 2 of the air conditioning chamber 1.

An indoor unit 14 of an air conditioner is arranged at a proper position in the space above the ceiling 13 so that the air conditioned by the indoor unit 14 is supplied to the air conditioning chamber 1 through a supply pipe 15. A return chamber 16 is provided in the vicinity of the indoor unit 14, and the air that has contributed to air conditioning is collected in the return chamber 16 and sent to the indoor unit 14. A return path 17 for returning air from the living room 7 and a return path 18 for returning air from the air conditioning chamber 1 are connected to the return chamber 16,
An adjustment damper 19 for adjusting the flow rate is provided on the return path 18.
Is provided.

When the conditioned air is supplied to the conditioned chamber 1, however, the conditioned air is blown out from the air-permeable ceiling part 4 and the heat radiating part 5 radiates heat to air-condition the living room 7. When the conditioned air is blown out from the breathable ceiling portion 4, clean air is blown out after being purified by the filter function. Further, since the heat radiating section 5 has good heat conductivity, heat is efficiently radiated. At this time, since air is blown out from the air permeable ceiling part 4 which is annularly provided so as to surround the heat radiation part 5, the conditioned air has ideal convection and the conditioned air is spread all over the living room 7. In addition, the return path 18 is adjusted by the adjustment damper 19.
By adjusting the amount of air flowing through the
The amount of air blown out from and the amount of heat radiated from the heat radiating section 5 can be adjusted. That is, when the flow rate returned from the return path 18 is increased, the amount of conditioned air blown out from the breathable ceiling part 4 is decreased and the heat radiation amount from the heat radiation part 5 is increased, so that the flow rate returned from the return path 18 is increased. When the amount is reduced, the amount of conditioned air blown out from the breathable ceiling part 4 increases and the amount of heat radiation from the heat radiation part 5 decreases. In the case of the embodiment, the cooling air or the heating air that has exchanged heat with the outdoor unit 14 is supplied to the air conditioning chamber 1 as the air conditioning air. However, even if cold air at night or underfloor air is supplied as the air conditioning air. Good.
