Title:
GEOTHERMAL ENERGY STORAGE SYSTEM
Document Type and Number:
Japanese Patent JPS59231395
Kind Code:
A
Abstract:

PURPOSE: To contrive to store simultaneously and effectively the cool-heat and the hot-heat energy by utilizing high heat insulating properties existing originally in the underground, and contrive to utilize timely the stored heat energy by a method wherein a water shut-off wall is provided at suitable location in the underground, a temperature stratification is formed in the geothermal water storage part for obtaining the temperature difference between a lower layer and an upper layer.

CONSTITUTION: A water shut-off wall 5 is constructed contacting on a base rock 2, located at the downstream side of a city area 1' for an underground water flow 4 and provided to be high as nearly correspond to the thickness of an underground water containing layer 3. The underground water flow 4 is shut-off by the water shut-off wall 5, the underground dam 6 is constructed under the lower part of the city area 1'. By selecting the injected water temperature and injected location for the underground dam 6, relatively lower temperature water in a lower layer 6a and higher temperature water than said water in an upper layer 6b are stored in a temperature stratification.
