Abstract

PURPOSE:To carry out floor heating with solar energy alone by disposing a solar heat collector and solar cells, installing a heat storage panel under the floor of a room, connecting the solar heat collector and the heat storage panel to each other with a duct and operating a fan with electric power generated by the solar cells. CONSTITUTION:In the case where solar radiation is available, air is warmed by a solar heat collector 1, and, at the same time, a fan 4 is operated by solar cells 2, whereby the warmed air is caused to flow to a heat storage panel 5, in which the warmed air flows on a heat storage material 7 or inside the heat storage material 7, and heat is emitted to the heat storage material 7 and an indoor side, so that floor heating can be carried out on the indoor side, and heat can also be stored in the heat storage material 7. Then, the air, which has passed through the heat storage panel 5, is induced by the fan 4 into the solar heat collector 1 via a duct 3 to be rewarmed. During the night when solar radiation is unavilable, the fan 4 is not operated, and heat is emitted to the indoor side from the heat storage material 7 to carry out floor heating.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating system for heating a room from the floor surface. More specifically, the invention relates to a floor heating system that utilizes solar heat.

0002

2. Description of the Related Art Conventionally, indoor heating has been carried out by heating the indoor air using stoves, fan heaters, and the like. However, the heated air rises, creating a temperature difference where the area near the ceiling is warmer and the area near the floor is lower. For this reason, underfloor heating, which heats rooms from the floor, has become popular. This type of floor heating is performed using carpets woven with heating wires.
A method was used in which pipes were laid to circulate hot water on the floor, and flooring material was placed on top of the pipes.

0003

[Problems to be Solved by the Invention] However, all of these methods use electricity, kerosene, or other fuel, and have the disadvantage of high energy costs.

0004

[Means for Solving the Problems] In order to solve these problems, the present invention performs floor heating by guiding the heat obtained by a solar heat collector to the floor using air as a medium, and also heats the floor. The system installs heat storage panels and performs floor heating while also storing heat, and mainly at night, the heat stored in the heat storage panels is released to perform floor heating. This project proposes a floor heating system that does not require energy costs by circulating air between the floors using a fan operated by solar cells.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A floor heating system according to the present invention will be explained in detail below with reference to the drawings. FIG. 1 is a configuration diagram showing an overview of the floor heating system, in which 1 is a solar heat collector, 2 is a solar cell, 3 is a duct, 4 is a fan, and 5 is a heat storage panel. In other words, the solar heat collector 1 is installed outdoors, such as on a roof, and can be of a flat plate type or a vacuum tube type.In particular, since it uses air as a medium, a vacuum tube type has less heat leakage and a higher temperature heat source. This is preferable because it can be obtained.

The duct 3 moves the air heated by the solar heat collector 1 to the heat storage panel 5 laid on the floor, and also moves the air from the heat storage panel 5 to the solar heat collector 1. The heat is circulated between the solar heat collector 1 and the heat storage panel 5. A fan 4 is attached to this duct 3, and the fan 4 circulates the fluid.

[0007] The fan 4 is operated by electricity generated by the solar cell 2. This will cause fan 4
is activated when there is sunlight and heat is being collected by the solar heat collector 1, and the system can be simplified without requiring a special control device.

The heat storage panel 5 temporarily stores the heat collected by the solar heat collector 1 on the back side of the flooring, and performs heating by dissipating the heat mainly at night. The heat storage panel 5 is installed on the entire floor or partially depending on the size of the house, the installation space for furniture, etc. To explain further, the heat storage panel 5 is shown in FIG.
As shown in a) and (b), it is made up of an envelope material 6, a heat storage material 7, and a pipe 8, and the air sent through the duct 3 is transferred to a space 9 above the heat storage material 7 or inside the heat storage material 9. pipe 8
The heat is stored in the heat storage material 7 by passing the heat through the heat storage material 7. This heat storage material 9
For example, it has CaCl2 .6H2 O as its main component and is sealed in a high-density polyethylene container.
CaCl2.6H2O stores and releases heat of ΔH1 to ΔH4 through a reversible reaction as shown in Chemical Formula 1. In other words, it stores and releases heat when changing from solid to liquid and from liquid to solid.

[0009]

[Chemical formula 1]

[0010] The operation of the entire system will now be explained. When there is sunlight, the air is heated by the solar heat collector 1, and at the same time, the fan 4 is operated by the solar cell 2, and the heated air moves to the heat storage panel 5. In the heat storage panel 5, heated air moves over or within the heat storage material 7, and heat is released to the heat storage material 7 and the indoor side, and the indoor side is heated under the floor, and the heat storage material 7 performs heat storage. be exposed. Next, the air that has moved through the heat storage panel 5 is guided to the solar heat collector 1 via the duct 3 by the fan 4, and is heated again. Furthermore, at night when there is no sunlight, the fan 4 does not operate, and the heat from the heat storage material 7 is released indoors, resulting in floor heating. In this way, solar heat can be utilized day and night.

What has been described above is an example of the floor heating system according to the present invention, in which the heat storage panel 5 is only the heat storage material 7,
It is also possible to lay a floor material on top of the heat storage material 7 with a space therebetween so that air can flow between the heat storage material 7 and the floor material. It is also possible to use water, antifreeze, gas, or the like as a medium in the solar heat collector 1, to secondarily warm the air using this medium, and to circulate this to the heat storage panel 7.

[Effects of the Invention] As described above, according to the floor heating system according to the present invention, it is possible to perform floor heating using only solar energy, and by using a heat storage panel in combination, floor heating can be performed day and night. It can be carried out. ■Furthermore, since the fan is also operated by solar cells, it can be turned on when heat can be collected by the solar collector, and turned off when heat cannot be collected, without the need for a special control device. It has the following effects and characteristics.
