Title:
融雪システム
Document Type and Number:
Japanese Patent JP6921401
Kind Code:
B2
Abstract:
To provide a snow-melting system capable of suppressing initial cost and having excellent heat efficiency.SOLUTION: A snow-melting system 10 comprises a circulation pipe line 17 passing through a first pipe 11 constituting a heat exchanging mechanism 80, and a second pipe 12 buried in a snowmelt region 60. The first pipe is installed inside a sewer conduit 70. The circulation pipe line includes a sealed expansion tank which absorbs the volumetric change of a heat exchange medium, and circulates the heat exchange medium in a sealed state. Heat collected in the first pipe via the heat exchange medium circulating through the circulation pipe line is dissipated in the second pipe to melt snow.SELECTED DRAWING: Figure 1
