Description

Hot air supply apparatus using solar

The present invention relates to a warm air supply using solar heat, and more particularly to a warm air supply using solar heat that can be used for home heating and drying.

The development of alternative energy is increasing in importance in order to proactively cope with international environmental treaties such as GR, TR, and WTO in terms of developing and utilizing environmentally friendly energy resources to secure future energy sources and protect the environment. Therefore, it is very urgent to develop and commercialize the use technology of unlimited, pollution-free solar energy among alternative energy resources.

The use of solar heat for heating purposes in homes can be broadly classified into natural solar systems and facility solar systems. Here, the natural solar system uses solar power without any power, and processes the outside of the area facing the south side with a glass window and puts a heat collecting wall therein so that the air warmed by the sun during the day through the air holes provided above and below the heat collecting wall. It is heated by circulation, and at night, heat accumulated in the heat collecting wall is transferred to the room through the wall to be heated. In addition, the facility type solar system uses mechanical power to forcibly store solar heat and sends hot water from a solar collector on the roof to a storage tank in the basement using a pump. It uses the water in this heat storage tank as a heating and hot water in a way that it stores. The hot water stored in the heat storage tank on a sunny day can be used for about three days of heating and hot water, and an auxiliary heat source is installed in the basement in case of a cloudy day or when there is not enough heat. Of course, this auxiliary heat source is installed with a system of less capacity than a normal home. In addition, the house adopts a greenhouse type, so as with a living room of a natural type house, it is possible to generate heat by directly receiving heat from the sun and to become a greenhouse.

By the way, since most of these methods are limited to heating and social needs are mainly limited to heating, it is necessary to have a system for each purpose in order to use solar heat more efficiently. Therefore, for the practical use of solar heat, the development of a system capable of supplying a heating and other calorie-needed consumers without a large change of the system and improving the thermal efficiency must be preceded.

Therefore, the technical problem to be achieved by the present invention is to provide a warm air supply device using solar heat that can be used for heating and drying by blowing the heated air.

1 is a schematic view for explaining a warm air supply using solar heat according to the present invention.

Hot air supply apparatus using the solar heat of the present invention for achieving the above technical problem, the solar heat collector having a cover and an air circulation passage is open at both ends; A heat collecting chamber having a first inlet and a first outlet and installed at a lower end of the solar collector so as to be connected to both ends of the air circulation passage; A duct having a second inlet port and a second outlet port, wherein the second inlet port is connected to the heat collecting chamber and the second outlet port is connected to a heat supply source separately provided outside; And a fan installed inside the duct to forcibly transfer air in the heat collecting chamber to the heat supply destination.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a schematic view for explaining a warm air supply using solar heat according to the present invention.

Referring to FIG. 1, the warm air supply device of the present invention includes a solar heat collector 100 rotatably installed, a heat collecting chamber 200 in which air heated by the solar heat collector 100 is stored, and a heat collecting chamber 200. An overheating source includes, for example, a duct 300 connecting the indoor or grain storage of a general building, and a fan for forcibly transferring the heated air in the collecting chamber 200 to the heat receiving unit although not shown.

The solar collector 200 has an air circulation passage 110 as a heat absorber composed of a cover 120 made of transparent glass and a copper tube with open ends. Therefore, the cool air introduced into one end of the copper tube 110 is heated while circulating through the copper tube 110 to flow out to the other end of the copper tube 110. At this time, the solar collector 100 is installed to be rotatable so that the thermal efficiency is improved by rotating in the sunshine direction.

The collection chamber 200 is provided with an inlet 210 through which cold air is introduced and an outlet through which heated air is discharged although not shown. And the heat collecting chamber 200 is installed at the lower end of the solar heat collector 100 so that both ends of the copper tube 110 installed in the solar heat collector 100 is located in the heat collecting chamber 200. The cold air introduced into the heat collecting chamber 200 is heated while circulating through one end of the copper tube 110 and is discharged to the other end of the copper tube 110 to collect in the heat collecting chamber 200. At this time, in order to prevent the mixing of cold air and hot air in the heat collecting chamber 100, it is preferable to separate the heat storage chamber, that is, the heat storage chamber except the inlet 210 and the inlet 210 of the heat collecting chamber 200. Do. Thus, the outlet port is located in the heat storage chamber. Then, one end of the copper tube 110 installed in the solar collector 100 is located on the inlet 210 side, the other end is located on the heat storage chamber side. On the other hand, the opening and closing device 220 may be installed in the inlet 210 to block the cool air flowing into the solar collector 100 and the heat collecting chamber 200 as necessary.

The duct 300 has an inlet connected to the outlet of the collecting chamber 200 and an outlet 310 for allowing hot air in the collecting chamber 200 to flow out to a heat supply unit provided separately. At this time, inside the duct 100, a fan for forcibly transferring hot air in the heat collecting chamber 200 to the heat supply destination is installed.

On the other hand, the present invention is not limited to the above-mentioned Taeyoung heat collector, and the outlet of the duct is provided in plural numbers according to the use.

As described above, according to the warm air supply device using the solar heat of the present invention, the hot air heated by the solar collector can be forcedly transferred using a fan, and thus it can be used for heating and drying of grains.

In addition, it is possible to reduce the cost by using a separate hot air heater, it can be used environmentally friendly.

The present invention is not limited to the above embodiments, and it is apparent that many modifications are possible by those skilled in the art within the technical idea of the present invention.
