PURPOSE: A greenhouse using solar heat and geothermal heat is provided to easily maintain the inside temperature of a greenhouse at an appropriate level by using solar heat and geothermal heat, thereby decreasing expenses for installation and maintenance. CONSTITUTION: A greenhouse comprises a wall part(101) which forms the space for plant cultivation; a storage part(102) which stores water and air; a temperature adjusting part(103) which drives water in the storage part to flow out to the cultivation space and flow in again for heat exchanging; a water supplying part(104) which supplies water of the storage temperature adjusting part to flow through the temperature adjusting part; and a roof part(105) which seals the cultivation space. The greenhouse includes an secondary temperature adjusting part(106) which connects the temperature adjusting part to the storage part; and a branching part(107) which supplies the water flowing through the temperature adjusting part to the storage part directly or let the temperature adjusting part supply. An air supplying part(108) includes an air blower which leads the air of the storage part to flow to the cultivation space; and a discharging pipe in which the air of the storage part is flowed and sent out to the cultivation space. After the temperature adjusting part is heated by solar heat, the water of the temperature storage part flows through the temperature adjusting part and is stored in a heated water storage part. |
