地中熱利用ヒートポンプシステムの水平埋設式地中熱交換器装置
Document Type and Number:
Japanese Patent JP5859731
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an underground heat exchanger device of horizontally burying type, of an underground heat-utilizing heat pump system, the underground heat exchanger device suppressing reduction in moisture in the underground shallow region and securing a sufficient heat exchange amount to eliminate reduction in a heat exchange efficiency.SOLUTION: The underground heat exchanger device of horizontally burying type includes: a heat exchanging trench 4 excavated to a predetermined depth in an approximately rectangular cross-section in the ground; a first underground heat exchanger part 31 where a circulation fluid for performing heat exchange between the underground circulates, that one type fluid passage selected from a continuous U-shape type fluid passage formed in such a way that a U-shape part facing one direction and a U-shape part facing a direction opposite to the one direction are alternately formed while meandering, a continuous loop type fluid passage formed in such a way that a series of circular ring parts is formed, and a spiral type fluid passage formed spirally, the three type fluid passages being to be buried substantially horizontal in a first depth region of a predetermined depth from a surface of the ground in the heat exchanging trench; and a sheet-shaped moisture maintaining member 35 which is buried between the surface of the ground and the first underground heat exchanger part and prevents moisture in the underground from being discharged to the atmosphere.
