Description

Building insulation structure

The present invention relates to a building insulation structure.

In a typical building, an insulation structure is formed to maintain the temperature inside the building. Conventionally, the method of lowering the heat transfer between the inside of the building and the outside air is mainly used by installing insulation on the outer wall of the building.

By the way, the thermal insulation method through the installation of heat insulators have a limit in their effectiveness when the temperature difference between the inside of the building and the outside air is severe, such as cold weather or cold weather. In other words, when the temperature difference is severe, a lot of heat is also transferred through the heat insulator, and thus a problem in which a lot of energy is consumed for heating or cooling inside the building cannot be avoided.

The present invention provides a building insulation structure capable of efficiently preserving the temperature inside a building even in a large temperature difference environment.

According to one aspect of the invention, the outer wall forming the outer surface of the building, disposed on the outer wall, and includes a heat transfer heat pipe for supplying heat to the outer wall side or absorbs and releases heat from the outer wall side, The heat transfer heat pipe forms an intermediate temperature layer between the inside and the outside air of the building, thereby providing a building insulation structure that blocks direct heat transfer between the inside and the outside air of the building.

The heat transfer heat pipe may absorb or release heat energy using natural force.

At least a portion of the heat transfer heat pipe is buried in the ground, and when the ground is heated than the ground, the heat of the outer wall is transferred to the ground, and when the ground is cooler than the ground, Heat can be transferred to the outer wall side.

The heat transfer heat pipe may be connected to a solar collector that receives at least a portion of solar heat and stores the solar heat, and may transfer heat energy absorbed by the solar collector to the outer wall.

The heat transfer heat pipe may include a tubular heat pipe into which a working fluid is injected.

The outer wall may further include a heat insulating member interposed between the outer wall and the heat transfer heat pipe.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a house to which a building insulation structure is applied according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of a house to which a building insulation structure is applied according to an embodiment of the present invention.

Building insulation structure according to an embodiment of the present invention includes an outer wall 10 and a heat transfer heat pipe 20 for transferring thermal energy to the outer wall 10 side, it is possible to block direct heat transfer between the interior of the building and the outside air.

The outer wall 10 is a wall surrounding the outside of the building, and is a part that borders the inside of the building from the outside. Accordingly, if there is no open portion (for example, a door or window) in the building, heat is transferred through the outer wall 10 to the inside of the building and the outside air (outside air).

1 and 2, the building according to the present embodiment is a house, and the outer wall 10 includes a side wall 12 and a roof 14 of the house. Here, the bet, which is air inside the building, is disconnected from the outside with the outer wall 10 as a boundary.

The heat transfer heat pipe 20 supplies heat to the outer wall 10 side or emits heat from the outer wall 10 side, thereby blocking direct heat transfer between the inside of the building and the outside air. Specifically, in this embodiment, the heat transfer heat pipe 20 is disposed on the outer wall 10 to form an intermediate temperature layer between the building and the outside air, so that the interior of the building is formed with an intermediate temperature layer formed by the heat transfer heat pipe 20. Heat transfer is achieved. Here, the intermediate temperature layer is an area disposed between the building and the outside air, and has an intermediate temperature between the temperature inside the building and the temperature of the outside air. Therefore, the interior of the building is heat transfer with the intermediate temperature layer having a relatively small temperature difference, and heat transfer is not performed with the outside air having a large temperature difference, thereby reducing energy consumed for heating or cooling the building.

In particular, in this embodiment, the energy source forming the intermediate temperature layer can be obtained from natural power. That is, it is possible to supply heat to the heat transfer heat pipe 20 as a natural energy source or to absorb heat from the heat transfer heat pipe 20. Therefore, the building insulation structure of the present embodiment forms an intermediate temperature layer for insulation using renewable energy, and thus can continuously perform insulation and does not require additional energy costs.

1 and 2, in the present embodiment, the heat transfer heat pipe 20 may supply or absorb heat to the outer wall 10 side using geothermal energy. To this end, a portion of the heat transfer heat pipe 20 is buried in the ground to perform heat exchange with the ground. In general, the temperature of the ground is constant throughout the year compared to the ground. Therefore, the underground temperature is often between the temperature inside the building and the temperature between the outside air.

Accordingly, when the outside air on the ground is heated than the ground (for example, in the summer), the intermediate temperature layer having a lower temperature than the hot outside air can be formed by transferring the heat on the outer wall 10 side to the ground. On the contrary, when the ground is cooler than the ground (for example, in winter), the ground heat is transferred to the outer wall 10 to form an intermediate temperature layer having a higher temperature than the cold outside air.

3 is a view illustrating a flow of heat during heating in a house to which a building insulation structure is applied according to an embodiment of the present invention. Hereinafter, the operation of the building insulation structure according to the present embodiment will be described in detail with reference to FIG. 3.

In winter, as the outside temperature of the ground decreases, cold outside air is formed on the outside of the building, while inside the building, a warm bet is formed by heating. As a result, a large temperature difference occurs between the outside and the inside of the winter season.

As shown in FIG. 2 and FIG. 3, in the present embodiment, by installing a heat transfer heat pipe 20 which extends to the ground on the outer wall 10, direct heat transfer between the outside air and the inside of a large temperature difference can be blocked. Since geothermal heat is continuously transmitted to the heat transfer heat pipe 20 embedded in the ground, an intermediate temperature layer by the geothermal heat transferred by the heat transfer heat pipe 20 is formed on the outer wall 10. Accordingly, the bet of the building heat exchanges with the intermediate temperature layer, and a heat transfer path is formed in which the outside air exchanges with the intermediate temperature layer. As a result, the building's bet heat exchanges with the intermediate temperature layer where the temperature difference is relatively small, thereby reducing heat loss due to the temperature difference. Therefore, energy consumption required for heating the building can be reduced.

At this time, as the heat transfer heat pipe 20 of the present embodiment, a tubular heat pipe into which a working fluid is injected may be used, and thus heat transfer without delay may be performed to the outer wall 10. Specifically, a vibrating tubular heat pipe may be used.

The vibrating tubular heat pipe has a structure in which the inside of the tubule 22 is sealed from the outside after the working fluid 23 and the bubble 24 are injected into the tubule 22 at a predetermined ratio. Accordingly, the vibrating tubular heat pipe has a heat transfer cycle for transporting a large amount of heat in latent form by volume expansion and condensation of the bubble 24 and the working fluid 23.

Looking at the heat transfer mechanism, the heat absorbing portion (20a) is nucleate boiling (Nucleate Boiling) by the amount of heat absorbed by the bubbles 24 located in the heat absorbing portion (20a) is the volume expansion. At this time, since the tubule 22 maintains a constant internal volume, the bubbles 24 located in the heat dissipating portion 20b dissipating heat as much as the bubbles 24 located in the heat absorbing portion 20a have a volume expansion so as to contract. do. Accordingly, as the pressure equilibrium in the tubule 22 collapses, a flow including vibrations of the working fluid 23 and the bubbles 24 in the tubule 22 is accompanied, and accordingly, the temperature due to the volume change of the foam 24 is caused. The heat dissipation is carried out by the latent heat transportation by lifting and lowering.

Here, the vibrating capillary heat pipe may include a capillary tube made of a metal material such as copper and aluminum having high thermal conductivity. Accordingly, while conducting heat at a high speed, the volume change of the bubbles 24 injected therein can be caused quickly.

In addition, the heat pipe formed of the tubule 22 may have a large heat transfer area to volume, and thus may rapidly absorb or release a large amount of heat. In addition, since there is no restriction on the direction of heat transfer, heat transfer is excellent in any direction, and there is an advantage in that the arrangement is free.

On the other hand, the communication structure of the vibrating tubular heat pipe can be both an open loop (close loop) and (close loop). In addition, when there are a plurality of vibrating tubular heat pipes, all or part of the vibrating tubular heat pipe may be in communication with a neighboring vibrating tubular heat pipe. Accordingly, the plurality of vibrating capillary heat pipes may have an open loop or closed loop shape as a design necessity.

As shown in Figure 1 and 2, the tubular heat pipe of the present embodiment may be formed in the form of alternately reciprocating ground and ground. Accordingly, during winter heating, the portion of the tubular heat pipe buried in the ground becomes the heat absorbing portion 20a and the portion installed on the outer wall 10 becomes the heat dissipating portion 20b, thereby transferring the geothermal heat to the outer wall 10 side. And an intermediate temperature layer may be formed on the outer wall 10.

At this time, in order to protect the tubular heat pipe from external contamination and impact, a cover member 40 covering the tubular heat pipe may be further installed. At this time, the cover member 40 may partition the intermediate temperature layer from the outside to maintain the temperature of the intermediate temperature layer for a long time.

In addition, a heat insulating member 30 may be installed between the outer wall 10 and the intermediate temperature layer to further reduce heat loss from inside the building. As shown in FIG. 2, in this embodiment, the heat insulating member 30 is installed to cover the outer wall 10, and the heat transfer heat pipe 20 is installed on the heat insulating member 30, whereby the outer wall 10 and the intermediate temperature are provided. It is possible to reduce heat transfer between layers.

On the other hand, in the present embodiment, but the formation of the intermediate temperature layer using the geothermal heat of natural force is not limited to this, various natural forces can be used to form the intermediate temperature layer.

For example, when heating a building in winter, the energy needed to form the intermediate temperature layer can be obtained from solar heat. Specifically, a portion of the heat transfer heat pipe 20 may be connected to a solar collector which receives and stores solar heat. Accordingly, the heat transfer heat pipe 20 may form an intermediate temperature layer between the inside of the building heated by heating and the cold outside air by transferring the heat energy absorbed by the solar collector to the outer wall 10 side.

In addition, by converting the natural force in the form of kinetic energy such as wind or hydropower into heat energy to supply heat to the heat transfer heat pipe 20 may be used to form an intermediate temperature layer.

Although the above has been described with reference to embodiments of the present invention, those skilled in the art may variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed.

Many embodiments other than the above-described embodiments are within the scope of the claims of the present invention.

According to embodiments of the present invention, by forming an intermediate temperature layer on the outer wall side of the building using heat energy using natural forces such as geothermal and solar heat, it is possible to block direct heat transfer between the inside of the building and the outside air.

In addition, since the interior of the building is heat transfer with the intermediate temperature layer having a smaller temperature difference than the outside air, it is possible to reduce the energy consumed for heating or cooling the building.
