Title:
GEOTHERMAL HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2016070597
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a geothermal heat exchanger which can improve geothermal heat exchange efficiency by actively utilizing a plurality of groundwater flows, and by efficiently impregnating rainwater immersed into the ground to a heat exchange well, can efficiently construct an underground portion compactly in a narrow site, and is easy in maintenance management.SOLUTION: A plurality of heat exchange wells 1 of an open hole are excavated so as to penetrate a plurality of aquifers by fresh-water excavation or compressed-air excavation, and to separately extend toward lower ends from upper ends. Circulation pipes 2 are arranged in the heat exchange wells 1 from the upper ends toward the lower end directions. Fillers 3 are filled into the surroundings of the circulation pipes 2 in the heat exchange wells 1, and make water pass through clearances. Heat exchange mediums 4 are arranged so as to be circulative in the circulation pipes 2. A heat pump device performs heat exchange by using the heat exchange mediums 4.SELECTED DRAWING: Figure 1
