PROBLEM TO BE SOLVED: To provide an operation room air-conditioning system capable of securing cleanness while constructing a thermal environment suitable for both of a patient and an operator.SOLUTION: An operation room air-conditioning system 10 includes: a first blow-out part 18 arranged on a ceiling 13 of an operation room 12 above a subject's area to send warm air to the subject's area； a second blow-out part 20 arranged around the first blow-out part 18 to send cool air having a temperature lower than that of the warm air to an operator's area around the subject's area； and a third blow-out part 22 arranged around the second blow-out part 20 along the second blow-out part 20 to send air to an area outside the operator's area at speed higher than that of the warm air and the cool air.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】患者と術者の両者にとって適切な温熱環境を構築しつつ、清浄度を確保することができる手術室空調システムを提供する。【解決手段】手術室空調システム１０は、手術室１２の天井１３における被術者領域の上方に配置され、被術者領域へ向けて温風を送風する第１吹出部１８と、第１吹出部１８の周囲に配置され、被術者領域の周囲の術者領域へ向けて温風よりも低温の冷風を送風する第２吹出部２０と、第２吹出部２０の周囲に第２吹出部２０に沿って配置され、温風及び冷風よりも大きい速度で前記術者領域よりも外側の領域へ向けて送風する第３吹出部２２と、を有する。【選択図】図２
