[0008]

According to the present invention, indoor air in the vicinity of the ceiling is sucked in by the indoor air suction means, conditioned by the air conditioner, and blown from the blow-out nozzle of the air conditioner. Can be.

The jet nozzle is located in an air-conditioning duct disposed in a room of a building, and is located between an air inlet near the ceiling of the air-conditioning duct and an air outlet near the floor. Since the conditioned air is blown from the jet nozzle toward the air outlet, room air is drawn into the air conditioning duct from the air inlet. As a result, the induced indoor air is mixed with the conditioned indoor air. Then, the air is pushed into the room from the air outlet near the floor.

[0010] By this mixing, a small amount of low-temperature (or high-temperature) air blown out from the jet nozzle is diluted with room air to become a large amount of appropriate temperature and humid air, which is located near the floor of the air conditioning duct. Since the air is blown out from the air outlet toward the living area, comfortable air is directly supplied to the living area.

At this time, by gradually extruding the large amount of air of appropriate temperature and humidity toward the living area, a temperature stratification is formed indoors. Then, when the heat is generated by the heat generated by a person or the like and rises to the vicinity of the indoor ceiling, the indoor air suction means guides the air to the air conditioner again to be harmonized. Therefore, by forming a temperature boundary layer with the air near the ceiling, a good situation can be created without considering the thermal load on the ceiling surface.

If the air-conditioning duct is arranged so that the pillar of the building is located in the air-conditioning duct, or if the air-conditioning duct is extended along the wall of the building, the air-conditioning duct can be attached and detached. It is easy, the air conditioning duct does not press on the indoor space, and the duct does not need to consider condensation, so that it can be implemented at low cost.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1A shows a first embodiment of the present invention . The air conditioner of the present embodiment includes an air conditioner 3 and a blower tube 7.
And an air-conditioning duct 6. The air-conditioning duct 6 is provided in a room of a building, and the air conditioner 3 is disposed in a storage space provided on a ceiling. And is configured to be able to perform a cooling operation and a heating operation.

The air conditioner 3 is connected to an indoor air intake means having an intake port 4 and an indoor air conduit 2, and draws in the indoor air 5 near the ceiling from the intake port 4, and for example, in the summer, dehumidifies and cools. Then, in the winter, the temperature and humidity of the indoor air are adjusted, such as by heating, to produce conditioned air, and the air is blown into the air conditioning duct 6 from the blowout nozzle 8 provided in the blower pipe 7.

The air conditioning duct 6 has an air inlet 11 near the ceiling and an air outlet 12 near the floor, and the outlet nozzle 8 has the air inlet 11 and the air outlet. 12 is disposed.
Therefore, if the conditioned air is blown from the blow nozzle 8 toward the air outlet 12, the room air near the ceiling is drawn from the air suction port 11 into the air conditioning duct 6, and As a result, the air 14 whose temperature and humidity are adjusted is pushed out from the air outlet 12 toward the room.

The temperature <br/> of the air blown from the blow nozzle 8, since in winter is set to be higher than the temperature of the room air, the air provided near the floor When the air is pushed out from the air outlet 12, it warms from the feet of a person in the living area. The air 1 whose temperature and humidity are controlled
Since the specific gravity of 4 is lighter than room air, a temperature stratification can be formed by natural convection.

Meanwhile, the temperature of air blown from the blow nozzle 8 in summer, is set to be lower than the temperature of the room air, its specific gravity is heavier than the room air. Therefore, in summer, if care is taken not to allow the air 14 whose temperature and humidity has been adjusted to flow out of the room, low-temperature air accumulates in a living area located below the room to form a layer. When cold air is pushed out one after another from the air outlet 12, a temperature stratification is formed from below, which rises when heated by internal heat generated by a person or the like, and is raised again to the air conditioner 3 by the indoor air suction means. .

As described above, the temperature and humidity of the air 14 are controlled.
Directly into the living space of human beings, it is possible to reduce the heat load from the ceiling as compared to the case where cold air is blown out from around the ceiling and the whole room is agitated. 70% for a building with a ceiling of 4m in height, 100% for a building with a ceiling of 6m or more
The heat load can be reduced.

Since the air 14 whose temperature and humidity are adjusted is directly pushed out into the living space, humans do not feel comfortable unless the temperature difference between the temperature and the temperature of the room air is kept small. Therefore, a large amount of air with a low temperature difference has to be pushed out slowly. Therefore, in the present invention, the room air near the ceiling is drawn into the air-conditioning duct 6 by the air inlet 11 without being blown directly from the conditioned air 8 through the air outlet 12, and the conditioned air is diluted by mixing with the conditioned air. The temperature is adjusted to the temperature and humidity that is most comfortable for humans, and the air is slowly pushed out from the outlet 12.

A pillar 21 of a building is located in the air-conditioning duct 6, and the air conditioner 23, the blower pipe 27, the air inlet 31 and the air outlet 32 are located symmetrically with respect to this pillar. Thus, the air in the room portion on the opposite side of the pillar 21 is conditioned by these. FIG. 1B is a cross-sectional view of the air-conditioning apparatus of the present embodiment, taken along the line 1B-1B.

If the pillars of the building are located in the air-conditioning duct, the air-conditioning duct does not protrude from the wall surface or the pillars, so that the interior space is not pressed and the columns are not condensed. Nor.

FIG. 2A shows a second embodiment of the present invention.
Referring to FIG. 2A, the air conditioner of the present embodiment includes an air conditioner 53, a blower pipe 57, and an air conditioning duct 56, and the air conditioning duct 56 is a wall of a building. The air conditioner 53 extends along the air conditioning duct 50.
6 are connected to the outgoing path and the returning path of cold and hot water (not shown), and are configured to perform a cooling and heating operation.

The air conditioner 53 is configured such that indoor air 55 near the ceiling is sucked by indoor air suction means having a suction port 61 so that air conditioning can be performed. This indoor air suction means has a switching damper 81 as outdoor air introduction means, and is configured to be able to introduce outdoor air into the air conditioning duct 56 stepwise according to the opening degree. .

The air conditioning duct 56 has an air inlet 61 near the ceiling and an air outlet 62 near the floor, and the outlet nozzle 58 is connected to the air inlet 61 and the air outlet. 62, so that if the conditioned air is blown out toward the air outlet 62, the indoor air near the ceiling from the air suction port 61 will be removed from the air conditioning duct 56. And both are mixed in the air conditioning duct 56. And the air outlet 6
The air 64 whose temperature and humidity have been adjusted is blown from 2 toward the room.

At this time, if the switching damper 81 is opened and outdoor air is introduced according to the opening degree, not only can fresh air be introduced into the room, but also the switching damper 81 can be opened.
Is switched so that only the outdoor air is supplied to the air conditioner 53, a so-called outdoor air cooling effect can be expected, so that an energy-saving operation can be performed.

FIG. 2B is a sectional view taken along line 2B-2B. The air conditioning duct 56 extends along the wall surface of the wall 50, and a plurality of air conditioners are provided in the air conditioning duct 60. I can put it.

As described above, the air-conditioning duct 6 extends along the wall surface 50.
Since 0 is extended, the air conditioning duct does not protrude into the room, and dew condensation on the wall can be prevented.

[0029]

According to the present invention, a temperature stratification can be formed in a room, and only a residential area can be air-conditioned, so that the heat load from the ceiling can be reduced.

Further, since the temperature stratification is formed at a temperature close to room temperature, a heat source (cold water) at a relatively high temperature is sufficient, and the refrigerator can be operated with high efficiency and energy is saved. In addition, well water at about 15 ° C. can be used.

Further, since the air conditioner can be arranged near the point where air conditioning is performed, the external static pressure can be reduced, and the size and cost of the device can be reduced.
