In this study, indoor air environment in a hospital operating room was measured to support evidence-based HVAC system design for a health care facility. The indoor contaminants measured in this study include PM10, carbon monoxide, carbon dioxide, formaldehyde, total bacteria colony, and volatile organic compounds which are specified in Indoor Air Quality Act of Korea. The measurements were carried out in the operating room before and during a laproscopic surgery. It was found that the measured PM10, carbon monoxide, formaldehyde concentrations were very low compared to the IAQ Act guideline, which indicates that the supplied fresh air for those contaminants maybe excessive. The result implies that there exists an energy saving potential by reducing ventilation rates for the operating room. On the other hand, the carbon dioxide concentration showed up to 1791 ppm at the maximum level, which could lower medical staff's concentration during an operation. The study suggests that appropriate HVAC system designs based on actual indoor contaminant generation characteristic are required for both energy saving and acceptable indoor air quality. |
