Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a house for central cooling and heating using a wall space (including underfloor space and attic space).

[Conventional technology]

In a conventional house, a heat insulating material is provided on a wall body or the like to improve the habitability, and heat in and out of the inside and outside of the house is blocked.

[Problems to be Solved by the Invention]

However, in such a house, there is a disadvantage that the radiant heat from the sun through the opening or the hot air emitted from various home appliances and the human body is sunk in the house especially in the summer. In addition, even if the openings such as windows are opened, the warmed air is trapped in the space behind the hut, which raises the perceived temperature in the living space. Furthermore, when using an air conditioner, etc., the air will be locally cooled, which will cause the physical condition to deteriorate due to the temperature difference due to the movement to each part space, and the cold air has the property of descending, so the hot air in the attic space will be It remained. For this reason, a large number of indoor air conditioning units were required to control all rooms. Further, even in the winter season, heating by the stove and the like is a solid room heating, so there is also a disadvantage of receiving a heat shock. In addition, the heat generated in the living space is trapped in the space behind the hut, and this heat is not used and is only released to the outside.

[Means for Solving the Problems]

In view of such a point, the present invention connects the attic space and the underfloor space with the space inside the wall, disposes the heat insulating material on the outer wall and the roof, and connects the attic space and the underfloor space through an air conditioner. In addition, the underfloor space is connected to each other with a soil heating layer, a concrete layer, and a heating medium pipe composed of a heat medium pipe embedded in the concrete layer.In the summer, air in the underfloor space is piped through the pipe. , Cools with an air conditioner and discharges it into the attic space, lowers the space inside the wall to cool the living space, and in winter, warm air in the attic space is blown to the underfloor space through a pipe, and By heating this air in the soil heating unit and raising the space inside the wall, the cold air in the living space is removed, and a house with improved habitability and thermal efficiency is proposed.

〔Example〕

A house according to the present invention will be described in detail below with reference to the drawings. FIGS. 1 (a) and 1 (b) are explanatory views showing a typical embodiment of the house A, in which 1 is a back space, 2 is a living space, 3 is an underfloor space, and a ceiling 19 and a floor 20 respectively. It is the internal space of the house A divided by. Reference numeral 4 denotes a heat insulating layer which blocks at least heat from entering and exiting from the inside and outside of the house A, and secondarily has soundproofness, airtightness, and fireproofness. To further explain, the heat insulating layer 4 is composed of a roof heat insulating layer 5 and an outer wall heat insulating layer 6, and each has a board shape, a mat shape,
The sheet-like material, the roof material, the outer wall material and the like are integrated with each other. Examples of the former are polystyrene board, polyurethane board, polyisocyanurate foam board, sheathing board, sheathing insulation board, wood chip cement board, wood wool cement board,
Glass wool mats, etc., or composite boards of these, etc., and by arranging metal roofing materials, roof tiles, etc. on their surfaces, arranging metal panels, tiles, ceramic panels, ALC boards, etc. To form the outer wall. Further, examples of the latter are a panel integrally formed with a surface material, a heat insulating core material and a back surface material as required, an ALC exterior panel, a wood chip cement panel, a wood wool cement panel, etc., which are main pillars, studs, etc. The outer wall heat insulating layer 6 and the roof heat insulating layer 5 are formed by arranging the outer wall heat insulating layer 6 and the roof heat insulating layer 5.
Reference numeral 7 denotes an inner space of the wall, which is provided between the heat insulating layer 6 of the outer wall and the inner wall 21. The attic space 1 and the underfloor space 3 are connected to each other, and the air cooled and blown by the air conditioner 9 described later is naturally convected. It is a space flowing by. A pipe 8 connects the attic space 1 and the underfloor space 3 via an air conditioner 9. The air conditioner 9 has at least a blowing function and a cooling function, and has a heating function, a dehumidifying function, a dust removing function, and the like as necessary, and is specifically a cooler, an air conditioner, or the like.
More specifically, the pipe 8 and the air conditioner 9 suck the air in the underfloor space 3 by the pipe 8 in the summer, cool it, and discharge it to the attic space 1, and in the winter, the air from the living space 2 The air in the attic space 1 in which hot air is squeezed is forcibly blown to the underfloor space 3 or heated to be blown. In addition, although the air conditioner 9 is arranged in the attic space 1 in FIG. 1, it may be arranged in the underfloor space 3 or outside the house A. 10 is the earth heating part, which is an underfloor space 3
It heats the inside and blocks the ingress of moisture from the ground. The soil heating unit 10 is composed of a soil heat insulating layer 11, a concrete layer 12 and a heat medium pipe 15 as shown in FIG. To further explain, the soil insulating layer 11 is made of rigid plastic foam such as polystyrene foam, polyurethane foam, and phenol foam, and has a closed-cell foam structure with a compressive strength of about ³⁰ to 100 kg / m ³ , or an ALC plate. , A wood chip cement board, a wood wool cement board, and the like, having a thickness of 10 to 100 mm. The soil heat insulation layer 11 prevents the heat from being released to the ground when heating the soil through a heat medium such as a greenhouse in the heat medium pipe 15 and discharging the heat to the ground to perform the soil heating. It is for. When the soil insulating layer 11 is made of a hard plastic foam having a closed-cell foam structure, etc., it has moisture resistance and does not allow water from the ground to enter the house A. However, an ALC board or a wood wool cement board is used. When a wettable material is used, it is preferable to lay a moisture-proof sheet 16 as shown by a chain double-dashed line or in the middle (not shown) between the soil heat insulating layer 11 and the concrete layer 12. . The concrete layer 12 functions as a heat storage material and a heat dispersion material from the heat medium pipe 15, and by embedding the heat medium pipe 15, water should be stored in the heat medium pipe 15 and should be frozen. It also helps prevent the heat medium pipe 15 from bursting in the event of an accident. The concrete layer 12 is, for convenience, a reinforced base concrete layer 13 and a soil concrete layer.
It is divided into 14 categories. The reinforced base concrete layer 13 is a layer mainly for facilitating the piping of the heat medium pipe 15.
The reinforcing base concrete layer 13 can also be formed by using concrete or by using a PC board.
Further, the soil concrete layer 14 functions as a heat radiating portion for burying the heat medium pipe 15 and for uniformly heating the air in the underfloor space 3. Heat medium pipe 15
Is for piping as shown in FIGS. 3 (a) and 3 (b), for example, and it is preferable to cover from the heat source 17 to the entrance / exit on the reinforced base concrete layer 13 with a heat insulating material 18. The heat medium pipe 15 is made of a copper pipe, a plastic pipe, or the like, and heats the soil by passing a heat medium such as an antifreeze liquid or a heat medium gas inside.

Here, the flow of the space in the house A will be briefly described.
First, in the summer, as shown in FIG. 1 (a), the air in the underfloor space 3 is sent to the air conditioner 9 through the pipe 8 and is cooled and dehumidified in the air conditioner 9 before being transferred to the attic space 1. Is released. This air descends in the in-wall space 7 and moves to the underfloor space 3 due to the wind pressure due to the release and the humidity difference. At this time, the living space 2 is also cooled via the inner wall 21,
When descending from the attic space 1 to the underfloor space 3, a part of the air leaks from the ceiling 19 and the inner wall 21 directly into the living space 2 for cooling, so there is no hot air inside the house A, and Since the entire interior of the house A is cooled, the sensible temperature is lowered and the habitability is greatly improved. Further, in the winter season, as shown in FIG. 1 (b), the air in the attic space 1 is sent to the air conditioner 9, and when the air conditioner 9 has a heating function, the air is heated and then the pipe 8 is used to provide an underfloor space. Released to 3. Since this air is uniformly heated in the underfloor space 3 by the earth heating unit 10 , it mainly rises in the in-wall space 7 and part of the living space 2 and moves to the attic space 1. Therefore, floor 20, inner wall 21
Since the cold air in the vicinity can be removed and the entire house A is heated, the temperature difference between the rooms becomes small and the habitability is improved.

The above description is only one example of the house A according to the present invention, and the air conditioner 9 can be installed outdoors as shown in FIG. In addition, the space 1 behind the hut and the space 3 under the floor of the pipe 8
It is also possible to attach an air collection / dispersion duct 22 as shown in FIGS. 5, 6 (a) and 6 (b) to the tip of the inside to suck and release air through the pipe 8 in a wide range. That is,
In FIG. 5, a pipe-shaped member made of metal or plastic is formed in an antenna shape or a spiral shape (not shown), and has slits 22a having a rectangular shape, a circular shape, an oval shape or the like. Further, FIGS. 6 (a) and 6 (b) show a material having voids composed of a communicating structure, for example, glass fiber,
Fiber materials such as plastic fibers, mineral fibers, metal fibers, polyurethane foam with an open cell structure, synthetic resin foams such as polyureafarm, porous ceramics, etc. pipes with a ring shape, square shape, triangular shape, polygonal shape, etc. 7 (a), which is formed in the shape of
It is arranged as shown in (b). In this case, since the void of the communicating tissue serves as the slit 22a, uniform suction and discharge can be performed. Although not shown, a fan may be arranged in the wall space 7 in the middle of the pipe 8 to forcibly generate the air flow.

〔The invention's effect〕

As described above, according to the house of the present invention, the outer wall,
Since the heat insulating layer is formed on the roof, cooling and heating can be performed efficiently. Since the air cooled by the air conditioner in the summer is released to the space behind the hut, the entire house can be cooled by the descent by the air. The sensible atmosphere will be improved as the space behind the hut will not be heated and the sensible temperature will drop. In the winter season, the soil heating unit functions to heat the entire house and the hot air in the attic space can be reused for heating, resulting in a house with good thermal efficiency. It is possible to block the infiltration of moisture from the soil and to make a durable house. There are effects and features.
