碩士 === 國立臺北科技大學 === 冷凍與低溫科技研究所 === 90 === In health care facilities, Air conditioning and ventilation system is a factor in the Prevention and Treatment of Disease ,not just a role of comfort, such as Mycobacterium tuberculosis are highly infectious and transported within air，the patient is the source of contamination ,Infectious isolation room keep Negative pressure to protect health care worker（HCW）and others from infectious patients, a positive pressure should be maintained in protective isolation rooms, if the patient is immunosuppressed persons（including bone marrow or organ transplant, leukemia, burn, and AIDS patients）. Ventilation is important in control contaminant concentrations, and nosocomial infection , High air exchange rates are used to pressurize the space and remove contaminants to protect patients, Many health care-related ventilation standards are based on ACH（Air changes per hour）,CDC and ASHRAE are using，but the ACH standard provides less air to small spaces and more air to large spaces, is unlikely to be related to the amount of contaminant generated, a different ventilation standard, airflow L/s•person（Liter per second per person）may be more indicative of expected contamination levels if the source of the contamination is related more to the occupants of the space, this research has conducted for isolation rooms, and discussion the variation of two ventilation standards with different droplet nuclei contamination concentration in isolation rooms. By means of a HEPA filter should also be used, exhaust air is directed through heat-recovery devices, to reduce the costs of operating ventilation systems, this study evaluate the potential of energy saving and rate of return on investment, the further detail study will form an basis of reasonable ventilation rate and annual energy consumption per square meter floor of isolation rooms.
