Description

[Detailed description of the invention] The present invention relates to energy saving in houses and the like.

Today, homes with insulation have become mainstream in the name of energy-saving homes.

However, the project was abandoned as there were major problems with insulating homes.

One is that insulation can prevent wood from corroding due to condensation inside the walls, and the other is whether insulation can truly save energy.

There is a tendency to think that insulating a house will save energy by preventing heat from escaping, but this is incorrect.

In winter, when there is solar heat outside, a building cannot receive heat even if it is insulated. In other words, it is better to have no insulation. However, insulation is required at night.

In the summer, insulation is necessary to keep out the sun's heat, but when it's cool at night, insulation is unnecessary.

This creates a contradiction between summer and winter, day and night, even with insulation, and unless this contradiction is removed, true energy savings will not occur.

The present invention is intended to eliminate this contradiction and provide us with a truly energy-saving house.

Hereinafter, the present invention will be described in detail based on the drawings.

There is a ventilation layer S surrounded by vertical ribs (1) and horizontal ribs (2), and on the back side there is a heat insulating plate (B), and above that there is a heat insulating box body with air intake and exhaust ports (3). A wall panel in which an external wall (4) is attached to variable heat insulating materials that are connected vertically and horizontally is attached to a building that has wall cavities (5) and 9 (9).

Let's take a look at how a building installed in this way works.

To explain this from a winter daytime when the sun is shining from the right-hand direction in Figure 4, the outer wall (4) is heated and the air in the ventilation layer S causes convection, causing high-temperature air to rise as shown by the arrow, and low-temperature air to rise. It descends, enters and exits through the intake and exhaust ports (3), and takes in high-temperature air into the wall cavity (5).

The high-temperature air gathers in the attic space (7) and flows through the partition cavity (6).
), flows through the wall cavity (9) to the underfloor space (8), and returns to the wall cavity (5) again to remove heat Wk. Inner wall materials are warmed by this air flow.

On the other hand, on the non-sun-irradiated surface, the air in the ventilation layer S is cooled and accumulates in the ventilation layer S, working together with the heat insulation plate (5) as a heat insulation wall.

In other words, even though the walls are the same, depending on the conditions of the outside world, it is possible to choose between insulation and non-insulation.

At night, the entire surface is naturally insulating and performs the same function as a non-solar surface.

In the summer, the normally provided underfloor ventilation holes and attic ventilation holes (not shown) are opened to release hot air and leave the heat inside the building, while also blocking sunlight during the day.

The one in which a ventilation layer (b) is attached to the heat insulating plate 03) side of claim 2 is for when there is a concern that the variable heat insulating material may be damaged during construction, and the air flow is The function is the same as in claim 1, except that the flow passes through the ventilation layer S1 and flows into the attic space (7).

As described above, it is a variable insulation building that absorbs solar heat during the day and insulates at night to save energy.

Claims (1)

[Claims] ■There is a ventilation layer S surrounded by vertical ribs (1) and horizontal ribs (2), and on the back side there is a heat insulating plate (B), and above it there are air intake and exhaust ports (3).
