Abstract

PURPOSE:To improve the living comfort and thermal efficiency by installing a heat exchanger in any of the spaces formed under the roof, under the floor, and in a wall and by allowing, through the heat exchanger, the space under the floor to communicate with the outdoors, and the space under the roof to communicate with the outdoors. CONSTITUTION:A heat exchanger 10 is installed in any of the spaces 1, 3, and 7 formed under the roof, under the floor, and in a wall respectively so as to ventilate the house A without loss of heat, that is, through ventilating holes 11 in the end walls, where the heat exchange 10 is installed in the space 1 under the roof, outside air is taken in and discharged into the space 1 under the roof in summer and into the space 2 under the floor in winter, whereas the air in the space 3 under the floor is released into the outdoors in summer and that in the space 1 under the roof is likewise released in winter. Heat exchange takes place between the air released into the outdoors and air taken into the house A from the outdoors so that the house A is ventilated while the heat is shut off from communication between the inside and the outside.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a house in which central heating and cooling is achieved by utilizing the attic space, the underfloor space, and the in-wall space.

[Prior Art] 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, while traditional houses placed great emphasis on insulation, they did not take any precautions for ventilation.

[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. In addition, a heat exchanger is installed inside the house, and the underfloor space and the outside are connected through this heat exchanger.
Connects the attic space to the outside, and in the summer, the air in the underfloor space is cooled by an air conditioner through a pipe and released into the attic space, and a portion of the air in the underfloor space is also released to the outside via a heat exchanger. At the same time, fresh air from outside is brought into the attic space, the interior wall space is lowered to cool the living space, and in winter, warm air from the attic space is blown into the underfloor space through pipes. At the same time, the heat exchanger releases the air from the attic to the outside, brings in fresh air from the outside into the underfloor space, and removes cold air from the living space by raising the air in the underfloor space in the wall space. This project proposes a house with improved livability and thermal efficiency.

(Example) A house according to the present invention will be explained in detail below using the drawings.
b) is an explanatory diagram showing a typical example of the above-mentioned house; It is space. Reference numeral 4 is a heat insulating layer that at least blocks heat from entering and exiting the house from the inside and outside, and secondarily has soundproofing properties, airtightness, and fireproofing properties. To explain further, the heat insulating layer 4 consists of a roof heat insulating layer 5 and an outer wall heat insulating layer 6, each of which is in the form of a board, mat, sheet, or integrated with the roofing material or the outer wall material.

Examples of the former include polystyrene board, polyurethane board, polyisocyanurate foam board, sheathing board, sheathing insulation board, wood chip cement board, wood wool cement board, glass wool mat, etc., or composite boards of these. The roof is formed by arranging metal roofing materials, tiles, etc. on the surface of the roof, and the outer wall is formed by arranging metal panels, tiles, ceramic panels, ALC boards, etc. Examples of the latter include panels in which a surface material, a heat insulating core material, and a back material are integrally formed, ALC exterior panels, wood chip cement panels, wood wool cement panels, etc. By placing it on the frame of the outer wall insulation layer 6,
It forms the roof insulation layer 5. 7 is the space inside the wall,
It is provided between the outer wall heat insulating layer 6 and the inner wall 14, communicates the attic space 1 with the underfloor space 3, and is a space in which air cooled and blown by an air conditioner 9, which will be described later, flows by natural convection. A pipe 8 connects the attic space l 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,
It is cooled and released into the attic space, and in winter,
The air in the attic space 1 filled with hot air from the living space 2 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.

10 is a heat exchanger, which is installed in either the attic space 1, the underfloor space 3, or the wall space 7;
This allows for internal ventilation without heat loss. That is, when the heat exchanger 10 is placed in the attic space 1 as shown in FIGS. 2(a) and 2(b), outside air is taken in through the gable ventilation opening 11, and this air is pumped into the attic space 1 in the summer as shown in FIG. As shown in figure a), the air is released into the attic space 1, and in winter, it is released into the underfloor space 3 as shown in figure (b), and in the summer, the air in the underfloor space 3 is released, and in the winter, the air in the attic space 1 is released to the outside. It is something that is emitted. At this time, heat exchange is performed between the air released to the outside and the air taken into the house A from the outside, preventing heat from entering and exiting the house A, and ventilation can be performed.

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

First, in the summer, as shown in Figures 1(a) and 2(a), the air in the underfloor space 3 is sent through a pipe 8 to an air conditioner 9, where it is cooled, dehumidified, etc. After that, it is released into the attic space 1. On the other hand, in the heat exchanger 10, air in the underfloor space 3 is released to the outside, and fresh air from the outside is taken into the attic space 1. For this reason, in the attic space 1, due to the cooling by the air conditioner 9 and the pressure caused by the discharge, the air moves down the wall space 7 and into the underfloor space 3. At this time, the living space 2 is also cooled through the inner wall 14. In addition, when descending from the attic space 1 to the underfloor space 3, some parts of the ceiling 12,
The air flows directly from the inner wall 14 into the living space 2 and provides cooling.Therefore, 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 and the livability is improved. Significantly improved.

In addition, in the winter, as shown in Figures 1(b) and 2(b), the air in the attic space l is sent to the air conditioner 9 through the pipe 8, and if the air conditioner 9 has a heating function, it is heated. After being heated, it is released into the underfloor space 3. In addition, the heat exchanger 10 releases the air in the attic space 1 to the outside, and takes in fresh air from the outside into the underfloor space 3. Warm air is blown into the underfloor space 3'T: and the pressure becomes high, so this air mainly rises through the wall space 7 and a portion of the living space 2, and moves to the attic space 1. Therefore, cold air near the floor 13 and inner wall 14 can be removed, and even if one room of the living space 2 is heated with a heater such as a stove, this residual heat will be distributed throughout the house A, and the air conditioning Since the air heated by the machine 9 is also distributed throughout the room, the temperature difference between each room is reduced, improving livability and allowing for ventilation.

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, the tips of the pipe 8 and the heat exchanger 10 in the attic space 1 and the underfloor space 3 are shown in FIGS.
) It is also possible to attach an air collection/dispersion duct 15 as shown in FIG. In other words, in Fig. 4, a pipe-shaped thing made of metal or plastic is shaped like an antenna, or although it is not shown in the figure,
It is formed in a spiral shape, etc., and has a slit 15a in a rectangular, circular, oval, etc. shape. Also, Fig. 5(a),
(b) is a material with voids made of continuous Mi weave, such as fibrous materials such as glass fiber, plastic fiber, mineral fiber, and metal fiber, synthetic resin foam such as polyurethane foam and polyurea foam with open cell structure, and porous material. It is made of ceramic etc. formed into a pipe shape with a ring, square, triangle, polygon, etc. cross section.
These are arranged as shown in FIGS. 6(a) and 6(b). In this case, the voids in the communicating tissue play the role of surin 15a, so that uniform suction and discharge can be performed. Further, although not shown, a fan may be disposed in the middle of the pipe 8, in the wall space 7, and in the heat exchanger 2S10 to forcibly generate air flow. Furthermore, the first
