Abstract

PURPOSE:To improve the living comfortableness and thermal efficiency by passing a thermal medium at the space under the floor through pipes which are buried in a layer of concrete overlying a heat-insulating grounded layer. CONSTITUTION:A grounded heating unit 10, designed to heat the space 3 under the floor and also shut off the entry of moisture from the ground comprises a heat-insulating grounded layer 11, a layer of concrete 12, and thermal medium- conveying pipes 15. When a thermal medium, such as hot water, is passed through the thermal medium-conveying pipes 15 to effect heating from the ground, the heat-insulating grounded layer 11 stops the heat from escaping to the ground. The layer of concrete 12 functions as a heat storage material and also as a material for dispersing the heat from the thermal medium- conveying pipes 15; by burying the pipes 15 in the concrete 12, if it should happen that water stands and freezes in the pipes 15, it is prevented for the pipes 15 to burst. The thermal medium-conveying pipes 15 are pipes of copper, a plastic material, or the like; heating by the grounded heating unit can be effected by passing a thermal medium, such as an antifreezing liquid or gas, therethrough.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a house that is centrally cooled and heated by utilizing the wall space (including the space under the floor and the rear space).

[Conventional technology]

In conventional houses, in order to improve livability, a heat insulating material is provided on the walls and the like to block heat from entering and exiting the house.

[Problem to be solved by the invention]

However, such houses have the disadvantage that radiant heat from the sun through the openings, or heat emitted from various home appliances and the human body, gets trapped inside the house, especially in the summer. Furthermore, even if openings such as windows are opened, warm air will remain trapped in the attic space, raising the perceived temperature in the living space. Furthermore, when using an air conditioner, the cooling is localized, which can cause people to become unwell due to temperature differences as they move from one space to another, and because cold air has a tendency to descend, hot air in the attic space is It remained. Therefore, a large number of indoor air conditioning units were required to air condition all rooms. Furthermore, even in the winter, heating by stoves and the like is for heating individual rooms, so there is still the disadvantage of being subject to heat shock. Furthermore, there was a disadvantage in that the heat generated in the living space was trapped in the attic space, and this heat was only released outside without being utilized.

[Means to solve the problem]

In view of these points, the present invention makes the attic space and the underfloor space communicate with each other through the wall space, provides insulation material on the outer walls and roof, and connects the attic space and the underfloor space via an air conditioner. The underfloor space is connected by a pipe, and in the underfloor space there is an earthen heating section consisting of an earthen insulation layer, a concrete layer, and a heating medium vibrator buried in the concrete layer. The air is cooled by an air conditioner and released into the attic space, and the interior wall space is lowered to cool the living space.In winter, warm air from the attic space is blown through pipes to the underfloor space. Moreover, this air is heated in the earthen floor heating section and the internal wall space is raised to remove cold air from the living space, thereby proposing a house with improved livability and thermal efficiency.

〔Example〕

The house according to the present invention will be explained in detail below using the drawings. FIGS. 1(a) and 1(b) are explanatory diagrams showing a typical embodiment of the above-mentioned house A, where ■ is an attic space, 2 is a living space, and 3 is an underfloor space, with a ceiling 19 and a floor 20, respectively. This is the interior space of house A divided by . Reference numeral 4 denotes a heat insulating layer that blocks at least heat from entering and exiting the inside of house A and the outside, and secondarily has soundproofing properties, airtightness, and fireproofing properties. To explain further, the insulation layer 4 is the roof insulation layer 5.
and an external wall heat insulating layer 6, each of which is in the form of a board, mat, sheet, or integrated with roofing material or external wall material. Examples of the former include polystyrene board, polyurethane board, polyisocyanurate foam board, sheathing board, sheathing insulation board, one piece of wood cement, wood wool cement board, glass wool mat, etc., or a composite board of these. A roof is formed by placing metal roofing materials, tiles, etc. on these surfaces, and an outer wall is formed by placing metal panels, tiles, ceramic panels, ALC boards, etc. on these surfaces. Examples of the latter include panels in which a surface material, a heat-insulating core material, and, if necessary, a back material are integrally formed;
ALC exterior panels, wood chip cement panels, wood wool cement panels, etc. are used to form the outer wall heat insulation layer 6 and the roof heat insulation layer 5 by arranging them on a frame such as main pillars and studs.

Reference numeral 7 denotes an in-wall space, which is provided between the outer wall insulation layer 6 and the inner wall 21, and connects the attic space 1 and the underfloor space 3, so that the air cooled and blown by the air conditioner 9, which will be described later, is circulated through natural convection. It is a space that flows 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 if necessary, a heating function, a dehumidifying function, a dust removing function, etc., and is specifically a cooler, an air conditioner, etc.

To explain further, the pipe 8 and the air conditioner 9 suck the air in the underfloor space 3 through the pipe 8 in the summer, cool it, and release it into the attic space 1, and in the winter, the air is sucked in from the living space 2. The air in the attic space 1 filled with hot air is forcibly blown or heated and blown into the underfloor space 3. Although the air conditioner 9 is arranged in the attic space 1 in FIG. 1, it can also be arranged in the underfloor space 3 or outside the house A. - The tier is an earthen floor heating section that heats the inside of the underfloor space 3 and also blocks moisture from entering from the ground. As extracted and shown in FIG. 2, this earthen floor heating section is composed of an earthen floor insulation layer 11, a concrete layer 12, and a heat medium pipe 15. To explain further, the dirt floor insulation layer 11 is made of polystyrene foam,
Hard plastic foam such as polyurethane foam or phenol foam with a density of 30 with closed cell foam fibers.
The material has a compressive strength of about 100 kg/n (100 kg/n) or is made of at least one type of ALC board, wood cement board, wood wool cement l-board, etc., and has a thickness of about 10 to 100 mm.

The earthen floor heat insulating layer 11 is for preventing heat from being released to the ground when heating the earthen floor by passing a heat medium such as hot water into the heat medium pipe 15.

Note that when the dirt floor insulation layer 11 is made of a hard plastic foam with a closed-cell foam structure, it has moisture resistance and prevents moisture from entering the house A from the ground.
When using a permeable material such as a board or wood wool cement board, a moisture-proof sheet 1 is installed as shown by the two-dot chain line or between the earthen floor insulation layer 11 and the concrete layer 12 (not shown).
6 is preferable. The concrete layer 12 functions as a heat storage material and a dispersion material for heat from the heat medium pipe 15, and by burying the heat medium pipe 15, water is stored in the heat medium pipe 15,
This also helps to prevent the heat medium pipe 15 from bursting when it freezes. Note that the concrete layer 12 is divided into a reinforced base concrete layer 13 and an earthen concrete layer 14 for convenience. The reinforced base concrete layer 13 is a layer mainly for facilitating piping of the heat medium pipe 15. This reinforced base concrete layer 13
It is also possible to form it by pouring concrete or using a PC board. In addition, the dirt floor concrete layer 14
The heating medium pipe 15 is buried therein and functions as a heat radiating part for uniformly warming the air in the underfloor space 3. The heat medium pipe 15 is illustrated in FIG. 3(a), for example.
The pipes are arranged as shown in (b), and it is preferable to cover the area from the heat source 17 to the entrance on the reinforced base concrete layer 13 with a heat insulating material 18. This heat medium pipe 15 is made of a copper pipe, a plastic pipe, etc.
It performs earthen floor heating by passing a heat medium such as antifreeze or heat transfer gas inside.

Here, the flow of air inside house A will be briefly explained.

First, in the summer, the air in the underfloor space 3 is sent to the air conditioner 9 through the pipe 8, as shown in Figure 1(a).
After being cooled and dehumidified by the air conditioner 9, it is discharged into the attic space 1. This air moves down through the wall space 7 and into the underfloor space 3 due to the wind pressure caused by the discharge and the temperature difference. At this time, the living space 2 is also cooled through the inner wall 21. When descending from the attic space 1 to the underfloor space 3, some of the air leaks from the ceiling 19 and the inner wall 21 directly into the living space 2. Because of this, there is no place for hot air to get trapped inside the house A, and since the entire interior of the house A is cooled, the sensible temperature also decreases, greatly improving livability. In addition, in the winter, as shown in FIG. 1(b), the air in the attic space 1 is sent to the air conditioner 9, and if the air conditioner 9 has a heating function, it is heated and then passed through the pipe 8 to the underfloor space. It is released in 3. Since this air is uniformly heated in the underfloor space 3 by the earthen floor heating unit 10, it mainly rises through the in-wall space 7 and partially the living space 2, and moves to the attic space 1. For this reason, floor 2
0. Cold air near the inner wall 21 can be removed, and
Since the entire house A is heated, the temperature difference between each room is reduced, and livability is improved.

What has been described above is only one embodiment of the house A according to the present invention, and the air conditioner 9 can also be installed outdoors as shown in FIG. In addition, pipe 8's attic space 1, underfloor space 3
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 pipe 8 to suck in and release air over a wide range. That is, in FIG. 5, a pipe-shaped thing made of metal or plastic is formed into an antenna shape, or a spiral shape (not shown), to form a rectangular, circular, oval, etc. sulin (22a).
It has the following. Figures 6(a) and 6(b) show materials with voids consisting of continuous structures, such as fibrous materials such as glass fibers, plastic fibers, mineral fibers, and metal fibers, open-cell am polyurethane foam, polyurea foam, etc. It is made of synthetic resin foam, porous ceramic, etc., formed into a pipe shape with a cross section of a ring, square, triangle, polygon, etc.
), <b). in this case,
The voids in the communicating tissue serve as the slits 22a,
Uniform suction and discharge can be performed. Further, although not shown, a fan may be disposed in the wall space 7 in the middle of the pipe 8 to forcefully generate air flow.

[Effect of the invention] As described above, according to the house according to the present invention,
It forms an insulating layer on the roof, allowing efficient cooling and heating. ■During the summer, the air cooled by the air conditioner is released into the attic space, allowing the cooling air to cool the entire house. ■Hot air does not get trapped in the attic space, lowering the perceived temperature and improving livability. ■In the winter, the earthen floor heating section functions to heat the entire house, and the hot air trapped in the attic space can be reused for heating, resulting in a house with high thermal efficiency.
