In order to use underground temperature as a greenhouse (14), if the air blower (8) and the ground blower (11) installed inside the underground part of the oil pipe (4) are operated at the same time, the air hole (4) The bar is drawn and drawn to the ground through the bar), and the large amount of air required in the limited space of the underground excavation hole 6 by the underground blower fan 8 is drawn out to the ground, thereby enabling efficient heating and cooling at low cost.

In particular, the present invention can perform a proper cooling and heating compared to the outside air, such as winter and summer season, which is connected to the water discharge-air circulation pipe (20) between the greenhouse 14 and the underground oil pipe (4) above the greenhouse The air of (14) flows back into the underground hole and is circulated to allow more efficient heating and cooling.

And the underground excavation hole (6) is narrow, the water discharge and air circulation (20) to maintain the temperature of the room temperature in the greenhouse 14 and the smooth use of suction and blowing at a limited capacity of the blowing fan (8,11) By using the outdoor air in summer, open the solenoid valve 31 to introduce outdoor air into the outdoor air supply pipe 30 to circulate natural underground or forced circulation underground to circulate the cold underground temperature into the greenhouse 14. In winter, the solenoid valve 32 in the middle of the water discharge-air circulation tube 20 is opened to allow air at room temperature in the greenhouse 14 to flow through the circulation tube outlet 22 having a filter to circulate in the basement layer. Geothermal temperature can be used in the greenhouse 14 at room temperature.

And during rainy season, the rainwater that has fallen into the roof of the greenhouse 14 is collected by the water tank 28 using the water reservoir 28, and then filtered. Then, the rainwater outlet pipe 27 and the valve 26 are opened. Should be used as agricultural water in greenhouses.
