Description

Solar Heating System {SOLAR HEATING SYSTEM}

The present invention relates to a solar heating system, and more particularly, to a solar heating system capable of heating indoors without having to provide a separate heating device by accumulating solar heat and transferring the accumulated heat with air.

Typically, most energy sources rely on fossil fuels or nuclear power, and scientists estimate that fossil fuels will be depleted within the next 50 years due to limited reserves, and global warming and environmental pollution due to their use. It causes serious environmental problems.

On the other hand, nuclear power plants produce a lot of energy, but they have dangerous problems such as radiation leakage and nuclear waste treatment, so there is a limit to relying on a stable energy source.

As a way to solve the problem of energy supply and demand can be considered the use of natural energy, natural energy can secure a permanent and environmentally friendly energy source using solar energy, wind power, hydropower, geothermal.

In addition, solar energy utilization technology can be largely divided into medium, low temperature and high temperature utilization technology. The medium and low temperature utilization technology is used for heating and hot water supply of houses, and the high temperature utilization technology is widely used for solar furnace and industrial process heat.

Briefly describing the principle of the use of solar heat, the heat medium heated in the solar collector installed outside the building is transferred to the heat storage tank and heats the water in the heat storage tank through heat exchange. The hot water heated in the heat storage tank is supplied to the room by a heating circulation pump that interlocks with a temperature controller that is turned on / off as the temperature is high and low at the room temperature, and used for heating and hot water supply.

However, according to such a solar heating system, there is a problem in that efficiency is lowered because it has to go through various media in order to transfer solar thermal energy to the room.

In addition, there is a costly problem for installing the heating system as described above.

Therefore, there is a demand for the development of a heating system that can efficiently collect solar heat and use it for indoor heating, and has a low installation cost.

The present invention has been made to solve the above-mentioned problems, and more specifically, by having a structure for collecting solar energy in the space portion between the window and the interior wall, the solar energy can be efficiently heated to a simple structure and low cost. The purpose is to provide a solar heating system that can be used.

Another object of the present invention is to provide a heating system that can efficiently use energy by generating indoor heating and hot water by using electricity produced by a photovoltaic device.

Solar heating system of the present invention for solving the above problems, the indoor wall formed with a vent to induce air flow into the interior space; A glass window forming a space portion between the interior wall and the interior wall; It is installed in the space portion and absorbs solar heat, and includes a heat storage body heat exchange with the air of the space portion.

According to the present invention, it is possible to save energy by efficiently accumulating solar heat and using the accumulated heat energy for heating in each room, and to reduce installation costs by implementing a simple structure as compared to a conventional solar heating system. There is this.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view showing a building structure to which the heating system of the present invention is applied, FIG. 2 is a cross-sectional schematic view showing part A of FIG. 1 in detail, FIG. 3 is a cross-sectional schematic view showing detail B in FIG. 1, FIG. Figure 1 is a schematic cross-sectional view showing a portion C of Figure 1, Figure 5 is a perspective view schematically showing a heat storage body and a heat storage control unit of the present invention.

In the heating system of the present invention, an indoor window 110 having an air vent 111 and 112 formed therein so as to induce air flow into the indoor space 1, and an outdoor window forming a space 130 between the indoor wall 110 and the indoor wall 110. 120, a heat storage body 140 is installed in the space 130 to absorb solar heat and heat exchange with air in the space 130.

A glass window may be installed at the central portion of the interior wall 110.

An upper vent 111 is formed on an upper portion of the indoor wall 110 to supply air of the abutment portion 130 exchanged with the heat storage body 140 to the room 1, and the space part 130 is provided. The lower vent 112 is formed at the lower portion of the indoor wall 110 so that the air of the interior 1 is introduced into the interior.

The outdoor window 120 is preferably provided with one or more ventilation openings (121, 122) of the openable structure.

The heat storage body 140 performs a function of providing heating heat to the room by heat-exchanging with the air in the space 130 after heat storage of the solar heat (蓄熱).

When sunlight is incident on the space 130, the air temperature of the internal space is increased. The air whose temperature is raised in this way is introduced into the room 1 through the upper layer part of the space 130 by convection, thereby heating the room 1.

However, since air has a low density and low heat storage ability to contain heat, it is not possible to supply sufficient heat energy for heating the room 1 to the room 1.

The heat storage body 140 is to solve this problem, and in view of the fact that the heat storage capacity is proportional to the density of the heat storage body 140 is preferably a metal material.

In the present embodiment, the heat storage body 140 is composed of a copper plate in consideration of density and price among metal materials.

In addition, since black has low reflectance and high solar energy absorption rate, a black carbon film is formed on the surface of the heat storage body 140 to increase solar energy absorption rate.

On the other hand, the heat storage body 140 is composed of a plurality of heat storage plate made of a plate-like arranged in the vertical direction. This is the same structure as blinds installed in the windows of a typical building to block sunlight.

The plurality of heat storage plates have a shape in which a rectangle is placed in the horizontal direction.

Since the amount of sunlight incident on the plurality of heat storage plates is maximum when sunlight is incident at right angles to the heat storage plate, the plurality of heat storage plates is preferably installed to be inclined upward.

In addition, when heating is not required or when there is little sunlight incident amount, it is preferable that the plurality of heat storage plates can adjust the vertical position.

To this end, as shown in FIG. 5, a heat accumulator adjusting unit 150 capable of adjusting a position and an inclination angle of the heat accumulator 140 is provided. The heat storage body adjusting unit 150 is composed of a tilt adjusting means 151 and the position adjusting means 152.

The inclination angle of the heat storage plate may vary depending on the altitude of the sun, so that sunlight is incident on the heat storage plate at a right angle. Therefore, the altitude of the sun is low in the winter solstice, so the inclination angle of the heat storage plate is set to the maximum (based on the horizontal line) so that the sunlight is incident at right angles to the heat storage plate. The inclination angle of the heat storage plate may be set to the minimum (when the horizontal line is used as a reference) so as to be incident at right angles.

As such, the inclination angles of the plurality of heat storage plates can be adjusted according to the altitude of the sun. For this purpose, the inclination angle adjusting means 151 is provided.

The inclination angle adjusting means 151 may be applied to a configuration for adjusting the angle of the conventional blind blades. That is, a configuration in which two rows that can be pulled by a person to a plurality of heat storage panels are connected and installed, and when one of the wires is pulled or the other wire is pulled, a plurality of heat storage plates may be folded or unfolded. Also, the heat storage plate angle can be adjusted by electric power.

Since the plurality of heat storage plates can be adjusted up and down position, when the heating is not required or when there is almost no solar light incident amount, the plurality of heat storage plates can be placed on the upper side.

To this end, the position adjusting means 152 that can adjust the plurality of heat storage plate vertical position is provided. The position adjusting means 152 may be applied to a configuration for adjusting the position of the conventional blind blades, similar to the inclination angle adjusting means 151. In other words, connecting two rows that can be pulled by a person to a plurality of heat storage plate, and pulling any one of them or pull the other row can be applied to the configuration that the position of the plurality of heat storage plate is adjusted.

The inclination angle adjusting means 151 may be provided with an inclination angle limiting means (not shown) such as a stopper so that the user can easily set the upper and lower limits of the inclination angle.

On the other hand, the plurality of heat storage plate, part of the heat storage plate 140b disposed below the heat storage plate by any one heat storage plate 140a located in the upper portion, the upper portion of the heat storage plate 140b located in the lower portion. It is desirable to block the sunlight.

That is, when viewed from the position where the sunlight is incident, the heat storage plate 140a located above and the heat storage plate 140b positioned below the heat storage plate 140a are provided to overlap by a predetermined area. In this case, an area portion of the lower heat storage plate 140b in which sunlight does not directly enter is a portion in which solar energy is stored. Therefore, when a plurality of heat storage plates are installed so as to overlap, the heat storage area is widened in a limited space, thereby improving heat storage capacity.

6 is a schematic cross-sectional view showing a heat storage body according to another embodiment of the present invention.

In the present embodiment, the heat storage body 140 ′ is formed of a plurality of heat storage plates inclined at a predetermined angle, and the ends of the heat storage plates are connected to each other so that adjacent heat storage plates have a step shape.

Such a structure does not need to configure the inclination angle adjusting means because the heat storage plate is fixed at a specific inclination angle. In this case, the inclination angle may be set to a median value of the angle at which the sunlight is incident at a right angle when the winter solstice and the winter solstice, or the angle of inclination at which the sunlight is incident at a right angle when the winter solstice is a reference to a winter solstice that requires a lot of solar energy for heating.

In order to smoothly introduce the air heated in the space 130 into the room 1, it is preferable that the fan 113 is installed.

The operation of the present invention constructed as described above will be described.

When the sunlight penetrates the outdoor window 120 and enters the space 130, the incident solar energy heats the air and the heat storage body 140 filling the space 130.

When the heat accumulator 140 is heated to a higher temperature than the air filling the space 130, heat is transferred between the heat accumulator 140 and the air.

When the temperature of the air inside the limited space 130 is increased, hot air moves to the upper side of the space 130 by the convection phenomenon, and the air moved to the upper side of the upper vent 111 and the room 1 It is introduced into the room 1 via the air pipe 160 installed on the ceiling finishing material (2).

The air introduced into the room 1 is cooled and lowered near the bottom of the room 1, and the air is introduced into the space 130 again through the lower vent 112.
