| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a trough solar thermal collector equipped with a solar-collection-unit washing mechanism capable of preventing increases in solar thermal collectors and an installation area due to degradation in solar thermal collection efficiency and an increase in maintenance workers.SOLUTION: A trough solar thermal collector for collecting sunlight by a curved reflector, heating a heat collecting tube by the collected sunlight, and receiving heat in a heat medium, includes: a cover hermetically sealing a range of the reflector and the heat collecting tube, and formed out of a light transmittance material; a washing device washing contamination of a surface of the cover; and moving means moving the washing device from a solar collection unit to an outside of the solar collection unit.
【課題】集熱効率の低下に伴う集熱器と設置面積の増大、保守人員の増加を防ぐことが可能な集光部洗浄機構を持つトラフ型太陽光集熱器を提供する。【解決手段】曲面の反射鏡により太陽光を集光し、集光した光により集熱管を加温し、熱媒体に受熱するトラフ型太陽光集熱器において、反射鏡および集熱管部分を密閉するカバーであって、光を透過する材料で形成されたカバーと、該カバー表面の汚濁を洗浄する洗浄装置と、該洗浄装置を集光部から集光部外部まで移動させる移動手段を有する。【選択図】 図１Ａ |
