Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a ventilation system and a ventilation method capable of sufficiently keeping indoor cleanness and preventing leakage of contaminated indoor air of a clean room and the like, as openings can be opened and closed by closing parts regardless of indoor differential pressure.SOLUTION: A control portion is constituted to switch an operation mode between a first operation mode for not driving differential pressure dampers 26, 30 by driving portions 28, 32, and a second operation mode for driving the differential pressure dampers 26, 30 by the driving portions 28, 32, by operating each of operation portions 35, 36, 37, 38. In implementing the second operation mode, the driving portions 28, 32 are respectively controlled to forcibly close openings 16a, 18a by the differential pressure dampers excluding the differential pressure dampers disposed on partitioning walls 16, 18 same as doors 20, 22 corresponding to the operated operation portions 35, 36, 37, 38, among the plurality of differential pressure dampers 26, 30.SELECTED DRAWING: Figure 2
【課題】室内差圧に関係なく閉止部による開口の開放および閉鎖が可能となるため、クリーンルーム等の室内清浄度の維持や汚染室内空気の漏出防止等を十分に行うことができる換気システムおよび換気方法を提供する。【解決手段】制御部は、各操作部35、36、37、38による操作によって、各駆動部28、32により差圧ダンパー26、30を駆動させないような第1の運転モードと、各駆動部28、32により差圧ダンパー26、30を駆動させるような第2の運転モードとの間で運転モードの切り替えを行うようになっている。第2の運転モードが行われる際に、複数の差圧ダンパー26、30のうち、操作された各操作部35、36、37、38に対応する扉20、22と同じ仕切壁16、18に設けられた差圧ダンパー以外の差圧ダンパーにより開口16a、18aを強制的に閉止するよう各駆動部28、32が制御される。【選択図】図2 |
