Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a building with a ventilation system, which can satisfactorily ventilate a room and can effectively use heat of exhaust air for heating and cooling.

Technical background of the invention and its problems With the recent airtightness and heat insulation of buildings such as houses, the need for planned ventilation in the room is increasing. However, in order to carry out planned ventilation in the room, when fresh air outside the room is introduced into the room and dirty air in the room is exhausted outside, warm or cold air in the room is also included. There is a risk that it will be discharged to the outside and reduce the cooling and heating efficiency.

Therefore, recently, a ventilation heating system for exchanging heat between the exhaust air and the supply air has been developed, and an attempt has been made to effectively use a part of exhaust heat energy of the exhaust air.

However, even in such a conventional ventilation and heating system, the exhaust heat energy of the exhaust air still cannot be effectively utilized, and there has been a demand for a building structure that further enhances cooling and heating efficiency.

On the other hand, as airtightness and heat insulation of a house progress, the occurrence of dew condensation on the wall of the house becomes a big problem.
Therefore, as a means for preventing the occurrence of dew condensation, a technique of providing a ventilation layer in the wall is known.

However, even in a house in which the ventilation layer is provided in the wall as described above, the air may not circulate sufficiently in the ventilation layer, and it may not be possible to effectively prevent dew condensation in the wall. Also,
Even in a building provided with such a ventilation layer, there has been a demand for a system that ventilates the room well without lowering the cooling and heating efficiency.

Purpose of the Invention The present invention has been made in view of such circumstances, and it is possible to satisfactorily plan ventilation in the room without lowering the cooling and heating efficiency, and effectively prevent dew condensation in the wall. The purpose is to provide a building with a ventilation system.

SUMMARY OF THE INVENTION In order to achieve the above object, the building according to the present invention is
An inner cover material that defines the inner space of one or more rooms, an outer cover material that defines the outer contour of a building, a heat insulating partition material that is stretched between the inner cover material and the outer cover material, and this heat insulation An outer ventilation layer formed between the partition material and the outer covering material, and a ventilation device for exhausting the air in the room into the outer ventilation layer, the ventilation device for the outdoor air in the room And a heat exchange section for exchanging heat between the air supply pipe in the air supply pipe and the exhaust air before being exhausted into the outer ventilation layer.

According to the building of the present invention, the relatively dirty air in the room is introduced into the ventilation device having the heat exchange section, and the air introduced into the room from the outside is also introduced into the ventilation device. And heat exchange is performed in this ventilation device.

Therefore, the heat or cold of the exhaust air is used to heat or cool the entire building, resulting in
It is possible to ventilate the room without reducing the heating and cooling efficiency. Further, according to the present invention, since the air in the room is forcibly exhausted continuously or intermittently in the outer ventilation layer, the air circulation in the outer ventilation layer becomes good,
It becomes possible to effectively prevent the occurrence of dew condensation.

Particularly, according to the present invention in which the exhaust air is heat-exchanged with the supply air from the outside and then exhausted into the outer ventilation layer, the thermal energy of the exhaust air is further applied to the heating and cooling of the room. It can be used effectively.

Detailed Description of the Invention Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is a schematic sectional view of a building showing an embodiment of the present invention, FIG. 2 is a horizontal sectional plan view of an outer wall of the building, and FIG. 3 is a vertical sectional side view of a lower portion of the building wall. FIG. 4 is a sectional view taken along the line IV-IV in FIG.

As shown in FIG. 1, in the building 1 according to the present invention, heat insulation is provided between the inner covering material 18 that defines the internal space of each room 10 and 11 and the outer covering material 20 that defines the outline of the building. A partition material 22 is arranged. As the heat insulating partition material 22, a fiber type heat insulating material such as rock wool or glass wool may be used, but a foamed plastic material is preferable from the viewpoint of water absorption and moisture resistance, and polyurethane foam, polystyrene foam, vinyl chloride foam, etc. are used. .

The heat insulating partition 22 is preferably constructed in a hermetically-sealed manner that encloses the rooms 10, 11 in a comprehensive manner.
Double vent layers 24, 26 that are not in communication with each other are formed on both the inner and outer sides of the. In the illustrated drawing, the outer vent layer 26 extends all around the sides of the insulation partition 22, and
The attic space 28 and the dirt floor space 30 communicate with each other. The outer ventilation layer 26 can communicate with the outside air by a ventilation port 32 formed in the lower part of the covering material 20 and a ventilation port 36 formed near the roof material 34. These ventilation openings 32 and 36 can be opened and closed by a lid as needed.

On the other hand, in the same drawing, the inner ventilation layer 24 extends all over the back side of the inner covering material 18 in each room, and the inner covering material 18 and the heat insulating partition material 22 are a part of support members (not shown). The structure does not contact each other except. Since it is difficult to construct the ceiling-side heat-insulating partition member 22 having the inner ventilation layer 24 so as to have a completely floating structure, the ceiling-side inner member 18 of the rooms 10 and 11 may be brought into contact with the structure.

The term "inner cover material" used in the present invention means a member that defines an internal space of one or more rooms, and is used in a broad sense including a wall inner cover material, a ceiling inner cover material, or a floor inner cover material. To be In addition, the concept of "outer covering material" used in the present invention means a member that defines the outline of a building, and is used in a broad sense including a wall covering material, a roof covering material, or a floor covering material.

The actual wall structure of the building described above is as shown in FIG. As shown in the figure, a slightly thin outer ventilation layer 26 is formed inside the wall outer covering material 20a constituting the wall outer covering material 20, and two layers of the heat insulating partition material 22 are sandwiched inside the outer outer ventilation layer 26. A rather wide inner ventilation layer 24 is formed. And inside the inner ventilation layer 24, the inner coating material that constitutes the inner wall of each room
It has a structure in which the in-wall material 18a as 18 is arranged. A heat storage material 42 may be attached to the back surface of the wall material 18a, if necessary. In Fig. 2, 44 and 46 are pillar materials.

On the other hand, the structures of the lower part of the wall and the floor are as shown in FIGS. 3 and 4. That is, the soil concrete 48
A heat insulating partition material 22 is disposed on the floor, and a floor material 50 made of expanded polystyrene, for example, is disposed on the heat insulating partition material 22, and a heat storage material 42 such as concrete is sandwiched on the floor material 50 to make a floor. The in-floor covering material 18b constituting the inner covering material 18 is arranged. In the soil concrete 48 as the floor covering material 20, voids 52 forming the soil space are formed all over, and the voids 52 form a part of the outer ventilation layer 26. In addition, passages 54 are formed all over the floor material 50,
The passage 54 forms a part of the inner ventilation layer 24. Since expanded polystyrene is a material having excellent heat insulating properties and durability, it is preferably used as the floor material 50.

In such a building 1, in the present invention, in the room 10,1
The air of 1 is exhausted into the outer ventilation layer 26 by a ventilation device. Specifically, for example, as shown in FIG. 1, an exhaust pipe 60 serving as a ventilation device that opens at a predetermined position in each of the rooms 10 and 11 is provided on the wall, floor, or ceiling back surface. The exhaust pipe 60 as the ventilation device is, in this embodiment,
It is connected to the heat exchange section 62. The heat exchange section 62 is also connected to an air supply pipe 64 that takes in outdoor air into the room. And
In the heat exchange section 62, the exhaust air sucked from the exhaust pipe 60 and the air supply air sucked from the air supply pipe 64 are heat-exchanged.

The exhaust air that has undergone heat exchange in the heat exchange section 62 is discharged to the exhaust pipe.
The supply air that has been exhausted into the outer ventilation layer 26 through 60a and has undergone heat exchange is supplied to the rooms 10 and 11 through the discharge side supply pipe 64a. Air-conditioning equipment that can heat or cool the air, or both, without directly blowing the heat-exchanged supply air into the rooms 10 and 11.
After air conditioning at 66, the air may be blown out into the rooms 10 and 11.

According to the building 1 according to the embodiment of the present invention,
The relatively dirty air in the room and the fresh air outside
Heat is exchanged in the heat exchange section 62, and then dirty air in the room is exhausted into the outer ventilation layer 26 through the exhaust pipe 60. Therefore, the heat or cold of the exhaust air can be used to heat or cool the entire building. As a result, each room 10, without reducing the heating and cooling efficiency,
Ventilation inside 11 becomes possible. Further, according to the present embodiment, the air in the room is forcedly exhausted into the outer ventilation layer 26 continuously or intermittently.
Since the 26 are formed all around the side surface of the building 1, the air circulation in the outer ventilation layer 26 is improved, and the occurrence of dew condensation can be effectively prevented.

Further, according to the present embodiment, since the total heat exchange type partition plate is used for the heat exchange section 62, the moisture contained in the exhaust air is removed. It can be effectively prevented.

Further, in the present embodiment, since the inner and outer double ventilation layers 24 and 26 that do not communicate with each other are formed between the outer covering material 20 and the inner covering material 18, the so-called two-sided environment that mitigates a severe external environment is formed. The next environment can be formed around the inner covering material 18, and a building with excellent heat insulation and heat retention can be realized. Further, when the outer ventilation layer 26 and the inner ventilation layer 24 are configured to extend over the backsides of the outer covering material 20 and the inner covering material 18, respectively, the dew condensation on the inner and outer covering materials 18, 20 in combination with the above heat insulation effect. Can be prevented particularly effectively,
The durability of the building can be improved.

It should be noted that the present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the present invention.

For example, the inner ventilation layer 24 shown in FIG. 1 does not necessarily have to be provided in the present invention, and it is also possible to construct a building without it. That is, the space on the room side formed by the heat insulating partition material stretched to form the outer ventilation layer is left in the place where the outer ventilation layer is required, and the inner ventilation is maintained. It may be provided as a layer, but this is not essential in the present invention. The intended purpose of the present invention can be achieved without inserting or laying a heat insulating material or a structural member into the space on the room side to close the space and form a ventilation layer. Further, it is preferable in performance that the outer ventilation layer 26 is provided all over the building, that is, on the entire wall, floor, roof, etc., but it is not always necessary for the entire building, and the discharge side exhaust pipe 60a is located. For example, it is also possible to construct a building in which the outer ventilation layer is partially present only in the wall portion. Further, if the discharge-side exhaust pipe 60a is located in the outer ventilation layer of the roof part, the effect of snow melting in the snowy region is great.

Effects of the Invention As described above, according to the present invention, after the heat exchange of the air in the room with the outdoor air in the heat exchange section of the ventilation device,
Since the air in the room is exhausted into the outer ventilation layer, the heat or cold of the exhaust air is used to heat or cool the whole or a part of the building, and as a result, the cooling and heating efficiency is improved. It becomes possible to effectively ventilate the room without lowering it. Further, according to the present invention, the air in the room is forcibly exhausted continuously or intermittently in the outer ventilation layer, which improves the air circulation in the outer ventilation layer and effectively prevents the occurrence of dew condensation. It becomes possible to do.

Further, according to the present invention, since the moisture contained in the exhaust air is removed during the heat exchange in the heat exchanging portion, the condensation in the wall can be effectively prevented in this respect as well.
