An object of the present invention is to provide an air-conditioning system capable of realizing energy saving.

[0004]

In order to solve the above-mentioned problems, a residential air-conditioning system according to a first aspect of the present invention is characterized by comprising the following components (a) to (c). (A) A closed intake space 3 having an opening provided in the underfloor outer wall 1a as an outside air intake 2 is formed under the floor, and a vertically sealed airflow space 6 connected to the intake space 3 is formed outside the house outer wall 7b. And the ventilation space 6 is formed in each room 7.
・ Connect to the supply inlet 8 of (B) A heat exchange unit 5 for heating or cooling the air moving from the intake space 3 to the ventilation space 6 is disposed near the intake space 3. (C) Each of the rooms 7 in the house has the above-mentioned supply inlet 8
A room air outlet 9 is provided at a position distant from the roof 10, an exhaust device 12 is provided between the roof 10 and the ceiling 11, and an exhaust intake of the exhaust device 12 and the room air outlet 9 are connected by an exhaust pipe 13. The air sucked by the exhaust device 12 is discharged outside. Furthermore, in the residential air conditioning system according to claim 2 of the present invention, in addition to the above-mentioned means, a dehumidifier 4 for dehumidifying the air in the intake space 3 is arranged in the intake space 3 or in the vicinity of the intake space 3. Features.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. A closed intake space 3 communicating with the outside air intake 2 is formed under the floor 1 of the house H. The outside air intake 2 is formed in four places from 1 to north, south, east and west on the outer wall 1a under the floor of the house H, and an intake space 3 is formed using the outside air intake 2 as an outside air introduction port. The intake space 3 is formed in a closed shape as a whole. However, it is not necessary to separately lay a cylindrical body in order to form a closed state, and an intake space 3 composed of a sealed space formed of a floor 1 member or the like of each room is formed, and communicates with the outside air intake 2 of the outer wall 1a. Further, a dehumidifier 4, for example, silica gel is disposed in contact with the intake space 3 and, for example, under the intake space 3 or in the intake space 3, to adjust the humidity of the conditioned air. Good.

The outer space 7 of the house communicates with the intake space 3.
b, for example, between the walls 7a, 7a of each room 7, a closed ventilation space 6 is formed in the vertical direction, and the ventilation space 6 communicates with the supply inlet 8 of each room 7. Let it. In the embodiment, the ventilation space 6 is formed by a floor 1 member and a wall 7a member of each room. The airtightness of the floor 1 and the walls 7a is sufficient as long as each material has the airtightness. The ventilation space 6 does not communicate with the space in the attic, which is an exhaust space.

A heat exchange unit 5 for cooling and heating is arranged in the intake space 3 under the floor, and the heat exchange unit 5 is moved from the intake space 3 to the ventilation space 6 as a ventilation space 6 on the side of a ventilation outlet. It is configured such that heat exchange (heating and cooling of the conditioned air) is performed with the conditioned air. In addition, the arrangement position of the heat exchange part 5 includes not only the inside of the intake space 3 but also the boundary part with the ventilation space 6 or the case where a part of the heat exchange part 5 is located in the ventilation space 6. The heat exchanger 5 may be provided with the heat exchanger itself, but when mechanical heat generation is an obstacle, the heat exchanger may be a separate type and only the heat exchanger 5 may be provided. In particular, when the heat exchange energy depends on solar heat, an energy medium (energy fluid / electric energy) is supplied to the heat exchange unit 5 to cause heat exchange.

Each room 7 in the house is provided with an indoor air outlet 9 at a position away from the supply inlet 8 and at or near the ceiling plate. Therefore, in the room 7, the supply inlet 8 and the indoor air outlet 9 are merely provided apart from each other, so that not only the room space can be effectively used, but also the design of the room is not impaired. Roof 10 and ceiling 11
And an exhaust device 12 is provided between them. And the exhaust device 12
Is connected to the indoor air outlet 9 by an exhaust pipe 13, and the air sucked by the exhaust device 12 is discharged to the outside. The exhaust device 12 may be basically a blower fan.

With the above configuration, the indoor ventilation space 6 can be
Since it was provided in the interior of the house without being provided in the part b, the thermal energy of the conditioned air was hard to leak out of the house and the thermal efficiency was good, and only the entrances 8 and 13 of the conditioned air were provided in each room 7. Not only does it take up less room, it can be used effectively, and it does not detract from the design of the room. Further, since it is not necessary to provide the supply inlet 8 and the indoor air outlet 9 on the outer wall 7b or the window side of the window of the house, not only is the design of the house easy, but also each room 7 is provided with the supply inlet 8 By separating from the indoor air outlet 9, unevenness of indoor air conditioning can be eliminated.

Further, by separating the heat exchanging section 5 and the exhaust device 12 and using a separate system for the ventilation of each device, various combinations of air conditioning and ventilation can be realized. Since the wall surface of the ventilation space 6 is also the wall surface of each room 7..., The air temperature in the ventilation space 6 heats and cools the wall surface of each room 7. The walls are also heated and cooled by radiant heat and the like, further improving the comfort of the occupants. In addition, the dehumidifier is placed in the intake space 3 or near the intake space 3,
For example, the humidity can be adjusted by laying down and laying on the ground surface constituting the lower surface of the intake space 3. In the description of the appended claims, corresponding reference numerals are given to clarify the correspondence with the embodiment, but the present invention is not limited to this.

[0011]

According to the present invention, the following effects can be obtained by the above configuration. 1. According to the first aspect of the present invention, since the indoor ventilation space 6 is provided inside the house without being provided on the outer wall 7b, the heat efficiency is good, and each room 7... It is heated and cooled by heat. In each room, only the entrances and exits of the conditioned air 8 and 13 are provided, and the room does not take up space. In addition, since it is not necessary to provide the supply intake 8 and the indoor air outlet 9 on the house outer wall 7b or the window side,
Not only is it easier to design the house, but also each room
By separating the supply intake port 8 from the indoor air outlet 9, indoor air conditioning can be performed evenly. Further, by separating the heat exchange unit 5 and the exhaust device 12 and using different systems for the air flow of each device, various combinations of air conditioning and ventilation can be realized.

2. According to the second aspect of the present invention, in addition to the above effects, the humidity of the entire house can be adjusted.
