Özet

This study is aimed at examining the validation and operation steps in a cleanroom, to reduce the rate of air changes per hour in the cleanroom to maintain the pressure difference except when not in use. Before changing the HEPA filters of 23 operating rooms in Gazi University Hospital, air change rate measurements were carried out and compared with the measurements of the last two years. Particles were counted to verify the ISO class of the operating theatres. Since the airflow rate decreases outside of working hours, the determination of the decontamination period, which is one of the validation steps, should be taken into consideration. In this study, the reduction of operating costs and greenhouse gas emissions are examined by considering different operating scenarios. It was calculated that 63.2% of energy savings can be achieved and 2.76 tons of CO2 emissions per year can be prevented for an operating room according to different operating scenarios.
