Title:
ENVIRONMENTALLY-FRIENDLY UNDERGROUND WATER HEAT UTILIZATION SYSTEM
Document Type and Number:
Japanese Patent JP2016070530
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an environmentally-friendly underground water utilization system capable of minimizing impact on an underground environment in terms of both a water temperature and water quality when sending underground water which is pumped up from the ground and used for heat exchange back to the ground.SOLUTION: An environmentally-friendly underground water utilization system comprises: a production well 1 to pump up underground water from the ground; a heating and cooling facility which uses thermal energy of the underground water pumped up through the production well 1; a heat regulator which brings a temperature of the underground water after being used in the heating and cooling facility close to an original temperature thereof; and a reflux pipe 18 to send the underground water which passes through the heat regulator back to the production well. A heating and cooling system mounted with a water-heat type heat pump 16 which uses the underground water as a heat source is best for the heating and cooling facility in terms of convenience. The heat regulator preferably has: a heat regulation hole 9 with a heat exchanger 11 installed therein; or heat exchange pipes horizontally arranged in the ground. Also, the reflux pipe 18 may have a plurality of discharge ports to allow the used underground water to be sent immediately below an underground water surface in the production well 1.SELECTED DRAWING: Figure 1
