CITY WATER HEAT SNOW-MELTING DEVICE, CITY WATER HEAT SNOW-MELTING SYSTEM AND CONTROL METHOD OF THESE
PROBLEM TO BE SOLVED: To provide a new city water heat snow-melting technology for enhancing efficiency of heat transfer by largely increasing the contact length to a city water pipe of a heat collection pipe, and capable of surely preventing the heat collection pipe from carelessly separating from the city water pipe even when receiving external force, while being inexpensively installable in any of new and existing city water pipes.SOLUTION: In a city water heat snow-melting device 1, a flexible heat collection pipe 40 of the predetermined length is heat-transferrably wound in a circumscribing spiral shape on an outer peripheral wall-predetermined length range of an object water supply pipe 3, and a heat radiation pipe 41 is buried in a laying shape under a pavement surface layer of a snow-melting object section 2, and a fluid circulation circuit 4 is provided by connecting one end of the heat collection pipe 40 to one end of the heat radiation pipe 41 and connecting the other end of the heat collection pipe 40 via a circulation pump 6 to the other end of the heat radiation pipe 41, and a heat exchange fluid 7 is filled in the fluid circulation circuit 4, and the heat exchange fluid 7 is forcedly circulated in the fluid circulation circuit 4, and low-temperature heat is collected from the object water supply pipe 3 and underground 5 via the heat collection pipe 40, and snow can be melted via the heat radiation pipe 41.SELECTED DRAWING: Figure 1
【課題】新設および既設の水道管の何れにも、低コストで設置できる上、採熱管の水道管への接触長を大幅に増やして熱伝達の効率を高めると共に、外力を受けた場合にも水道管から採熱管が不用意に離脱してしまうのを確実に防止できる新たな水道熱融雪技術を提供する。【解決手段】対象上水道管３の外周壁・所定長範囲に対し、所定長の可撓性採熱管４０を熱伝達可能とするよう外接螺旋状に捲き付け、融雪対象区画２の舗装表層下に、放熱管４１を敷設状に埋設し、該放熱管４１の一端に当該採熱管４０の一端を接続し、該放熱管４１の他端に循環ポンプ６を介して当該採熱管４０の他端を接続した流体循環回路４を設け、該流体循環回路４中に熱交換流体７を満たし、熱交換流体７を流体循環回路４中に強制的に循環し、採熱管４０を通じて対象上水道管３および地中５から低温熱を採取し、放熱管４１を介して融雪可能なものとした水道熱融雪装置１である。【選択図】図１
