Lack of natural ventilation: ① natural ventilation is variable, depending on the relative indoor outdoor weather conditions. Two driving forces generated by wind speed (wind and temperature difference) diverse. Natural ventilation is relatively difficult to control the air flow may be high in some parts, while other parts will no airflow. Under certain adverse weather conditions, may lead to a lower air exchange rate. ② lack of continued good vacuum conditions, natural ventilation will be difficult to control the wind, sometimes the risk corridor with adjacent room mutual contamination. ③ natural ventilation can not use dust filter; due to climatic reasons, security, cultural background as a result we are not used to open doors and windows closed, in such an environment will be very low ventilation rates. ④ natural ventilation is available only when the onset of the forces of nature; when high ventilation time, higher demands on the wind. ⑤ natural ventilation systems often stop working, normal operation is terminated due to a variety of reasons, including its doors not open, poor equipment damage, utility failures, design, improper maintenance, neglect of management. ⑥ although simple natural ventilation system maintenance costs low, but if not installed properly, the lack of funds to maintain the operating room purification price, the ventilation effect will be greatly reduced, the risk of airborne pathogens lead to an increase. These problems can be overcome by good design or use of hybrid ventilation. Other possible defects, such as noise, air pollution, contaminated insects, security also needs to be considered. Because of these problems, natural ventilation system not only can not serve as an effective infection control facilities, but these facilities caused by the spread of infectious diseases.
