An upper water storage layer 3, which is formed at a position lower than the ground G and collects rainwater in the rainy season to store water, and a lower water storage layer 3 located below the upper water storage layer 3, And a lower low-water layer 9 for storing water.

At this time, a heat insulating plate 6 partitioned to separate the upper low water layer 3 and the lower low water layer 9 is interposed between the upper low water layer 3 and the lower low water layer 9, and the heat insulating plate 6 Is formed by a circulation passage (8) for circulating the water of the upper side water layer (3) to the lower side water layer (9) so that rainwater is substantially collected in the upper side water layer (3) (9).

A waterproof layer is provided on the wall of the water storage space to prevent the inflow of water into each of the low water layer (3) (9) into the underground.

The circulation passage 8 may be provided with a mesh-like filter 8 'for filtering foreign substances. In addition, the upper surface and / or lower surface of the thermally conductive plate 6 may reflect heat The reflective film 7 can be applied to improve the thermal insulation.

The heat insulating plate 6 functions as a blocking film so as to prevent convection between the upper and lower water layer 3 and the lower water layer 6. For this purpose, the heat insulating plate 6 occupies most of the area of the water storage space And the circulation passage (8) is formed with a small hole size.

The present invention further includes an inflow pipe (10) having a circulation pump (14) for circulating water, and a first pipe (11) and a second pipe (12).

The inflow pipe 10 provided with the circulation pump 14 is connected to the lower low water layer 9 and the heat exchanger 1 to circulate water in the lower low water layer 9 toward the heat exchanger 1 , And an opening / closing valve 10 'is provided to selectively circulate the water. At this time, the inlet of the inflow pipe (10) is positioned below the lower water layer (9).

The first pipe 11 connects the heat exchanger 1 and the upper water reservoir 3 to circulate the water in the heat exchanger 1 to the upper reservoir 3. The first valve 11 ') Can be installed to selectively circulate the water. At this time, the outlet of the first pipe (11) is positioned above the upper water layer (9).

The second pipe 12 connects the heat exchanger 1 and the lower water layer 9 to circulate the water discharged from the heat exchanger 1 toward the lower water layer 9, A valve 12 'is provided to allow water to be selectively drained if necessary. At this time, the outlet of the second pipe (12) is positioned above the lower water layer (9).

A three-way valve 13 is provided on the drain pipe side of the heat exchanger 1 in a state where the first valve 11 'and the second valve 12' are omitted. The first pipe 11, The water discharged from the heat exchanger 1 can be drained to either the first pipe 11 or the second pipe 12 by connecting the first pipe 11 and the second pipe 12 to each other.

Preferably, a bubble tube 4 having a number of fine holes formed therein for generating bubbles is provided at the bottom of the upper water layer 3, and a blower 5 is provided at the end of the bubble tube 4, So that the water collected in the water storage space may be purified.

Further, a filtering net (2) may be provided to filter the foreign substances in the rainwater flowing from the paper surface (G) to the edge of the upper side water layer (3).

Hereinafter, the seasonal cooling and heating operation will be described with reference to FIG. 1, and the present invention will be further described.

In the winter season, since the temperature of the ground drops below zero, the upper water layer (3) is frozen from the water surface to form an ice layer. Therefore, the water temperature of the upper water layer (3) is always kept at 0 ° C, It is possible to suppress the water temperature drop of the low water layer 9 and the lower water layer 9 is blocked by the upper water layer 3 and the heat insulating plate 6, The temperature is relatively high due to geothermal heat. Further, the lower water layer 9, which is relatively in contact with the ground surface, has a higher water temperature.

Therefore, the water in the lower water layer 9, more specifically, the water at a higher temperature (compared to the average temperature of the winter season in winter) located in the lower portion of the lower water layer 9 through the inflow pipe 10 is introduced into the heat exchanger 1, The water discharged from the heat exchanger 1 is drained to the lower side water layer 9. At this time, the water drained from the lower side water layer 9 So that there is no change in the water temperature of the water located below the lower water layer 9 as much as possible.

On the contrary, in summer, the temperature of the ground is very high, so that the water temperature of the upper water layer (3) rises, but the specific heat of water is higher than the soil and surface water of the upper water layer (3) evaporates, 3 is prevented from being lowered due to the lower temperature of the water due to the lower temperature of water in the lower water layer 3 and the lower water layer 9 is blocked through the upper water layer 3 and the heat insulating plate 6 The water temperature is lower than that of the ground because it is located in the basement where the temperature of the four seasons is kept constant. Moreover, the water temperature in the lower part of the lower water layer (9)

Therefore, the water in the lower low-water layer 9, more specifically the lower-temperature water (compared to the average summer temperature on the ground) located below the lower low-water layer 9, is introduced into the heat exchanger 1 through the inflow pipe 10, The cooling water in the greenhouse 1 'can be cooled by circulating the cold water. At this time, the water to be drained is drained to the upper part of the upper water layer 3 so that the water temperature of the water in the lower water layer 9 I will not.

By such an operation method, it is possible to perform heating by using relatively warm water of the lower water layer 9 in winter, and cool by using relatively cold water of the lower water layer 9 in summer, It is very economical because it uses pure natural energy without a separate device for heating or cooling water.

However, if the outside temperature is too high or too low to control the indoor temperature of a greenhouse, a house, a house, etc. to a desired temperature, a separate heating and cooling system using artificial energy may be supplementarily used.

Although the cooling and heating system of the greenhouse 1 'has been described above with reference to the drawings, the subject of cooling and heating in the present invention is not limited to the greenhouse 1', but may be a greenhouse, a house, It includes various structures requiring heating.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
