Field of the Invention The present invention relates to a regenerative heating system using a solar absorber heat pipe and a solar heat collecting pipe heat storage tank and more particularly to a heating system using a vacuum tube solar water heater, The present invention relates to a regenerative heating system.

Greenhouse refers to a greenhouse covered with vinyl film for the cultivation of vegetable or cultivated tropical plants.

In recent years, crops such as field crops, flower plants and other fruit trees have been grown by vinyl houses regardless of the season.

These greenhouses are used not only in rural areas but also in the suburbs of the city. If the crops can be maintained at a suitable temperature for cultivation, the crops can grow and grow smoothly. It is common to cultivate crops by using them.

On the other hand, since the vinyl house has a high thermal conductivity due to the nature of the vinyl which forms the outer shell, the temperature inside the vinyl house is raised by the solar radiation during the day when the sunshine is strong, but the radiant heat is low at night or overcast days. Goes.

Therefore, it is common to use a separate heating system, such as a boiler or an electric heater, so that the temperature inside the greenhouse is not lowered at night or overcast.

However, when a separate heating system such as a boiler is used, it is possible to keep the room temperature of the greenhouse at the growth temperature of the crop, but there is also a problem that the risk of fire is high due to excessive heater operation in addition to high fuel cost.

Of course, the regenerative heating system according to the present embodiment can also be applied to a greenhouse structure other than the shape of the greenhouse 110 shown in FIG. Therefore, the scope of the present invention is not limited to the shape of the drawings.

The greenhouse 110 is a semi-cylindrical structure including a house envelope 110a and a house envelope 110b. The house envelope 110a and the house envelope 110b are mainly made of vinyl but can be replaced with other materials.

The house frame 110c and the house frame 110c are provided in the greenhouse 110 so that the house housing 110a and the house housing 110b can be supported. The house frame pipe 110c can be applied as an inner pipe as an empty pipe.

The room (suction) heat pipe 120 is a hose through which water flows, and can be installed at each position of the greenhouse 110.

For example, the room (intake) heat pipe 120 can be disposed on the inner wall surface, the upper ceiling, and the entire bottom floor of the greenhouse 110. The more the room (suction heat pipe) 120 is disposed, And can be advantageous.

Particularly, in the case of this embodiment, as shown in FIG. 2, a room air intake heat pipe 120 is further disposed in a house frame pipe 110c constituting a framework of the greenhouse 110. [

Since the air intake heat pipe 120 is disposed in the greenhouse 110 as well, natural heating water can be produced in a larger quantity, which can help construct a heating system.

The recovery pipe 111 is connected to a suction heat pipe 120 provided at each position of the greenhouse 110 and collects water in the absorption heat pipe 120 heated by solar heat or radiant heat .

Water heated by solar heat will be recovered to the recovery pipe 111 from the inner wall surface of the vinyl house 110 and the room air intake heat pipe 120 disposed at the upper ceiling, Water heated by radiant heat or geothermal heat can be recovered to the recovery pipe 111 from the arranged absorption heat pipe 120.

The hot water supply pipe 112 is connected to the second heat storage tank 142 and is disposed at each position of the greenhouse 110. The hot water in the second heat storage tank 142 is supplied to each position of the greenhouse 110 Supply. To this end, the second line L2 from the second heat storage tank 142 is connected to the second water circulation line 162 connected to the hot water supply pipe 112.

The hot water in the second heat accumulation tank 142 is supplied to the respective positions of the plastic house 110 through the hot water supply pipe 112 as in the present embodiment so that the plastic house 110 can be heated, Can be used.

Next, the vacuum tube type solar water heater 130 is connected to the recovery pipe 111 and functions to raise the temperature of the water recovered through the recovery pipe 111 in the vacuum tube solar heating system.

That is, the recovery pipe 111 is connected to the first water circulation line 161, and the first water circulation line 161 is connected to the vacuum solar water heater 130. Therefore, the temperature of the water in the recovery pipe 111 can be raised by the operation of the vacuum solar water heater 130 in the process of circulating the water along the first water circulation line 161, And may be stored in the first heat storage tank 141.

Next, the first heat storage tank 141 is a tank in which hot water having reached the target temperature is stored. The first heat storage tank 141 may be connected to the return pipe 111 through the first line L1 and the first water circulation line 161. [

Particularly, the first heat storage tank 141 applied to the present embodiment is connected to the return pipe 111 through the first water circulation line 161 and the first line L1, and the vacuum water storage solar water heater 130, That is, the hot water reaching the target temperature is stored.

The electrode boiler 150 is a boiler of a totally different concept different from the conventional electric boiler.

A conventional electric boiler is a method in which a heater rod not shown in the drawing is heated and a heated heater rod heats the water.

However, in the case of the electrode boiler 150, there is no heater rod, and an electrode (not shown) is applied. Even when electricity is supplied, no heat is generated in the electrode rod. Instead, when electricity is applied to the electrodes, the water between them ionizes and the water molecule acts as a flow resistor, generating Joule heat of 860 Kcal / Kw. As the temperature of the water rises, the resistance value of the water rises more rapidly, so that the desired high temperature water can be obtained in a shorter time.

The generated heat is vaporized at a low temperature due to the heat medium flow path inside the electrode rod, thereby further improving the thermal conductivity and amplifying the heat to water by rapid thermal diffusion, thereby heating the water more quickly by maximizing thermal efficiency.

[ Typically, a software routine may be stored in the memory 182. The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

The operation of the regenerative heating system having such a configuration will be briefly described.
