Hospital HVAC System


Sub-high efficiency filter life. Because only the early set, the secondary effect of the new air filtration system must be mixed with the indoor return air concentration given away after the interior, so that it increases the burden on the end of high efficiency filter and shorten its life. Concentration of fresh air in the system set up, due to set up a new independent filtration, air handling units, fresh air quality can be better guaranteed. Three levels of filter ventilation system is often not taken seriously set,[link widoczny dla zalogowanych], because when the operating room when not in use, outdoor air pollution measures by not filtering the exhaust pipe set into the room, once its put into use, indoor air quality is difficult to guarantee, at the same time self-cleaning time is greatly increased. Positive view of the above reasons, the new exhaust system located three filtration systems require. 3 Conclusion author's own experience and the design research and thinking related specifications, the design of the proposed clean operating room needs its own views and information on issues that require attention, are summarized as follows: (1) The clean area should be set separately cold and heat sources ; (2) clean air conditioning system should be based on an independent set of different levels, low levels of several rooms clean operating room may be considered together as a system. Surgical area and ancillary areas should be separated from air-conditioning settings; (3) airflow using (6) delivery, scheduling, fresh air system should be based on three levels of filtering measures; above is for colleagues to clean in the design of reference for when the operating room.

(Continued from page 47) (2) of the thermal injury patients are usually due to infiltration from the surface of the body out of plenty of fluids, suitable for low humidity of the room. While the overall thermal injury patients, when not covered towel blanket, and just simple cleaning cloth cover, do not lead to lower body temperature and maintain an appropriate dry, indoor air maximum temperature 3Occ, humidity 80%. (3) in the moving bed around 1000 to 10000 to ensure that air cleanliness. When the milk, for infants, in order to ensure air cleanliness, the use of clean bench. 8 Conclusion air-conditioning system to decide the reasonableness of its operation and future economy, and thus how to provide an orientation to the hospital proper, economic, and efficient air conditioning systems should be cautious of. Discussed in the article some of the design method, although some of the air-conditioning design in foreign hospitals have been more common, such as variable air volume systems. But it is relatively complex, difficult to control, high cost, its use is relatively tight in the capital should be cautious in the hospital air conditioning. Above proposed to discuss our views, hoping the design of the future to provide new ideas. References: [1] Fangzhao Hong, Zhou Wei. Hospital Air Conditioning Design Manual [M].
