First and second heat exchange media are filled in the first and second heat storage tanks 10 and 20, respectively. As the first and second heat exchange media, a gas such as air or a liquid such as water may be used. In the illustrated example, air is used as the first and second heat exchange media.

The heating unit circulates the first heat exchange medium in the house 1 to heat the first heat exchange medium by solar heat. To this end, the house 1 has a space in which plant crops are cultivated inside a semi-arc wall, and the wall has a double structure consisting of an inner wall and an outer wall. Specifically, referring to FIG. 7 for the inner wall structure of the house 1, a semi-arc shaped strut pipe 5a is driven to the ground at regular intervals on the ground, and then the strut pipe is crossed between the strut pipes 5a. It is fixed using the horizontal pipe 5b to be squeezed, and in this state, the outer side of the prop pipe 5a and the horizontal pipe 5b is surrounded by the first vinyl 5c. Up to this point, it is the same as a normal vinyl house. The outer wall 3 is formed to be spaced apart from the inner wall 5 by a predetermined distance. The outer wall 3 may be formed in various forms. In the illustrated example, as in the inner wall 5, the outer wall 3 is composed of a plurality of strut pipes 3a and horizontal pipes 3b, and the outer side of the support pipes and the horizontal pipes is formed. The outer wall is formed by enclosing the second vinyl 3c. Between the inner wall and the outer wall is an endothermic space (9) which is heated by solar heat during the day is formed.

In addition to the above-described dual structure, as shown in FIG. 3, the wall of the house 1 may be formed in a triple structure, of course. In this case, a first wall is formed at the innermost side, a second wall is formed outside the first wall, and a third wall is formed outside the second wall. The first and second walls are the same as the inner wall and outer wall structures described above. The third wall is also framed by a strut pipe 7a and a horizontal pipe 7b and surrounded by a third vinyl (not shown).

In the above-mentioned example, the vinyl house is mentioned as an example. In addition, the plastic house may be applied to a greenhouse formed of glass or other heat insulating member, or a low temperature warehouse requiring cold storage.

A first circulation pump 33 for circulating the heat exchange medium is provided.

The first heat exchange medium stored in the first heat storage tank 10 by the heating unit during the day is introduced into the heat absorbing space 9 of the house through the first supply pipe and heated. The heated first heat exchange medium flows into the first heat storage tank 10 through the first return pipe 31. The first heat exchange medium introduced into the first heat storage tank 10 exchanges heat with the second heat exchange medium stored in the second heat storage tank 20 using a heat pump. That is, the heat energy of the first heat exchange medium is transferred to the second heat exchange medium by the heat pump and stored in the second heat storage tank 20.

The heat pump is installed in the first heat storage tank 10 to heat exchange with the first heat exchange medium 11, and the second heat exchanger 21 installed in the second heat storage tank 20 to heat exchange with the second heat exchange medium 21. ), The first and second heat exchangers 11 and 21 are interconnected to form a closed circuit, the circulation pipe 13 through which the third heat exchange medium flows, and the expansion valve 19 installed in the circulation pipe 13. And a four-way valve 17 installed in the circulation pipe 13 so that the third heat exchange medium is circulated in the forward / reverse direction through the expansion valve 19 to form one cycle.

The high temperature first heat exchange medium introduced into the first heat storage tank 10 exchanges heat with the third heat exchange medium through the first heat exchanger 11. As the third heat exchange medium, a conventional refrigerant is used. The first heat exchange medium is cooled to low temperature by supplying a predetermined amount of heat to the third heat exchange medium, and the cooled first heat exchange medium is circulated back to the endothermic space 9 of the house through the first supply pipe 35 and reheated again. . The first heat exchange medium thus heated is supplied to the first heat storage tank 10 through the first return pipe 31 and continuously circulated. The first supply pipe 35 and the first return pipe 31 are provided with valves for opening and closing the flow path, respectively.

In order to store heat in the second heat storage tank 20 during the day, the second heat exchanger 21 installed inside the second heat storage tank 20 is used as a condenser by operating the four-way valve 15 of the heat pump. The first heat exchanger 11 provided inside the heat storage tank 10 is used as an evaporator. Therefore, the third heat exchange medium circulating the heat pump is cycled to the compressor → four-way valve → second heat exchanger → expansion valve → first heat exchanger → four-way valve → compressor. In this process, the third heat exchange medium absorbs heat from the first heat exchange medium in the first heat storage tank 10 and discharges the heat amount corresponding to the amount of heat and the amount of the compressor 15 from the second heat exchanger 21 so as to discharge the heat. The heat exchange medium is heated.

As described above, the heated second heat exchange medium is stored in the second heat storage tank 20, and the second heat exchange medium is circulated inside the house at night when the temperature decreases to heat the house.

Referring to FIG. 3, the first heat storage tank 10 further includes auxiliary heat source supply means for supplying underground air used as an auxiliary heat source. If the heat energy stored in the second heat exchange medium stored in the second heat storage tank 20 is consumed during night heating, the heat pump should be operated to heat the second heat exchange medium. In this case, the underground air is introduced into the first heat storage tank 10 by the auxiliary heat source supply means, so that the first heat exchanger 11 receives heat from the warm underground air, thereby increasing heat exchange efficiency, thereby reducing heating costs. At this time, the first supply pipe 35 and the first return pipe 31 connected to the house 1 may close the pipe by closing the valve.

A suction pipe 61 connected to the first heat storage tank 10 and the connection duct 65 as an auxiliary heat source supply means and extending from the ground to the porous rock layer 64 underground to suck underground air from the porous rock layer; It is provided in the connection duct 65 and has a blower 67 for sucking the underground air through the suction pipe (61). Underground air introduced into the first heat storage tank 10 by the blower 67 is discharged to the outside through the discharge duct 69 after heat exchange with the first heat exchanger 11.

Underground air drawn up from the underground rock layer 64 is always maintained at 14 to 16 ℃ can be used for cooling during the day or summer, for heating at night or winter. The rock layer 64 is a geological structure and geological medium with a very high inflow of precipitation, Lava Cave, hiding bone (where the precipitation is infinity due to the common or hot pole exposed on the surface), gravel, Oreum, rivers, seaweed-like sedimentary layers are formed, and there is an air layer of about 15 ° C in the underground space. The suction pipe 61 extends underground through the earth and sand layer 63 from the ground to suck underground air from the porous rock layer 64 in the base, and a plurality of vent holes for suction of air to the side corresponding to the rock layer. It is preferable that this be formed. The suction pipe 61 extends to the underground space by drilling and embedding the volcanic ash terrain.

Cooling is achieved by selecting the four-way valve so that the third heat exchange medium is supplied from the compressor 15 to the second heat exchanger 21 through the four-way valve 17, so that the refrigerant is selected from the compressor → four-way valve → first heat exchanger →. Cycles from expansion valve to second heat exchanger to four-way valve to compressor. In this process, the first heat exchanger 11 is cooled by performing heat exchange with cold underground air, thereby increasing the heat exchange efficiency by the first heat exchanger 11. The second heat exchange medium in the second heat storage tank 20 is cooled by the second heat exchanger 21, and the cooled second heat exchange medium can be cooled by supplying the cooled second heat exchange medium to the fan coil unit 53.
