地中熱交換装置
Document Type and Number:
Japanese Patent JP6754140
Kind Code:
B2
Abstract:
The invention provides an underground heat exchanger having a bottomed tubular flexible bag body accommodated in an accommodation hole portion in the ground, and an outer tubeaccommodated in the accommodation hole portion, vertically extending along an outer surface portion of the bag body and communicated in its lower end with a lower end of the bag body. The outer surface portion of the hardening resin bag body can cover an inner wall portion of the accommodation hole portion in a closely contact state with the bag body being inflated. The bag body is hardened in the covering state, a lining tubular body formed by the hardening can form a liquid storage tank for storing a heat medium liquid in its internal space, and the outer tube is pinched between the outer surface portion of the bag body and the inner wall portion. Therefore, the heat efficiency can be improved.
