Title:
GEOTHERMAL HEAT UTILIZATION SYSTEM
Document Type and Number:
Japanese Patent JP2020101309
Kind Code:
A
Abstract:
To provide a geothermal heat utilization system which enables geothermal heat to be effectively utilized.SOLUTION: A geothermal heat utilization system comprises: a heat exchange well 12 which is constructed underground and exchanges heat between a heat medium sent thereinto and the ground surrounding the heat exchange well 12; a heat medium extracting pipe 22 which is connected to the heat exchange well 12 and extracts the heat medium which undergoes heat exchange in the heat exchange well 12; and prevention means which prevents the heat medium inside the heat medium extraction pipe 22 from being heated by geothermal heat. The prevention means includes a groundwater extraction pipe 23 which is a double pipe where ground water, fluid to prevent the heat medium inside the heat medium extraction pipe 22 from being heated, flows along the lateral side of the heat medium extraction pipe 22.SELECTED DRAWING: Figure 1
