PROBLEM TO BE SOLVED: To provide an air conditioning system for preventing air-polluting substances such as dust from a surrounding space and an operator from being dragged to a patient side and for giving an optimum heating environment to the operator and a patient.SOLUTION: A center blow-off unit 11 is provided above a patient area of an operating room 1 and a circumference blow-off unit 13 is provided above an operator area adjacent to the circumference of the patient area, center blow-off air 21 is blown off from the center blow-off unit 11 to the patient area, and circumference blow-off air 23 is blown off from the circumference blow-off unit 13 to the operator area. The speed of the center blow-off air 21 is made higher than the speed of the circumference blow-off air 23, and the temperature of the center blow-off air 21 is made higher than the temperature of the circumference blow-off air 23.COPYRIGHT: (C)2013,JPO&INPIT【課題】周囲空間および術者からの粉塵など空気汚染物質の患者側への巻き込みを防止するととともに、術者と患者に最適な温熱環境を与える空調システムを提供する。【解決手段】手術室1の患者領域の上方に中央吹出ユニット11を、患者領域の周囲に隣接する術者領域の上方に周囲吹出ユニット13をそれぞれ設け、中央吹出ユニット11から患者領域に向かって中央吹出空気21を吹き出し、周囲吹出ユニット13から術者領域に向かって周囲吹出空気23を吹き出す。中央吹出空気21の速度を、周囲吹出空気23の速度より大きく、中央吹出空気21の温度を、周囲吹出空気23の温度より高くする。【選択図】図2
