Title:
MULTISTAGE TYPE GROUND WATER HEAT UTILIZATION SYSTEM
Document Type and Number:
Japanese Patent JP2016023914
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ground water heat utilization system for performing an efficient heat exchanging operation with ground water and capable of reducing the amount of ground water to be lifted up by arranging a configuration capable of reducing a cooling or heating load.SOLUTION: This invention relates to a ground water heat utilization system in which ground water pumped up from a withdrawal well drilled down to a level deeper than a depth ranging from a ground surface to aquifer is heat exchanged by a heat exchanger, and after this heat exchanging, the water is discharged out of the well through a discharging passage. The discharging passage is provided with a discharged water re-utilization pre-heater unit capable of utilizing the underground water after being heat exchanged by the heat exchanger as supplemental heat source, and the ground water after being heat exchanged by the discharged water re-utilization pre-heater unit can be utilized in a multi-stage manner by providing a water sprinkling part on a roof floor or wall surfaces of a building.SELECTED DRAWING: Figure 1
