GEO HYBRID SYSTEM
Document Type and Number:
Japanese Patent JP2020176745
Kind Code:
A
Abstract:
To provide an underground heat utilization system capable of combining the advantages of an open-loop system and a closed-loop system while solving the drawbacks of them.SOLUTION: An underground well 1 is provided in an aquifer. A pumping pipe 3 for pumping groundwater from the underground well 1 passes through a heat exchanger 11 and is connected to one port of a motor valve 5. To the other port of the motor valve 5, a return pipe 6 that returns to the underground well 1 via the heat exchanger 11 and the ground is connected. To the other port, a branch pipe 12 communicating with a water tank 14 is connected. A refrigerant circulation pipe 8 that supplies heat to a heat pump 16 is configured to exchange heat with the pumping pipe 3 and the return pipe 6 in the heat exchanger 11. In addition, switching the motor valve 5 to the return pipe 6 or the branch pipe 12 is automatically performed by a control device 15 based on the water level of the underground well 1 and then the heat load of the heat pump 16.SELECTED DRAWING: Figure 1
