SARS以后对民用建筑通风空调工程的反思和预期

Rethinking of ventilating and air conditioning engineering in civil buildings after SARS

从防止流行病传播的角度,分析了通风空调工程中存在的一些问题,并提出积极建议,包括正确处理常规运行和应急措施的关系、合理应用全空气空调系统和全新风直流式系统、改善空调系统新风量偏小的状况、改进空气过滤装置、解决冬季空气加湿和空调冷凝水问题、防止排风系统的“回流”现象,以及建筑不同空间的压力控制等。

Based on prevention of epidemic transmission, analyses some issues in ventilating and air conditioning engineering and puts forward positive advices, involving rightly dealing with the relation between conventional running and emergency measures, rationally applying all-air systems and all-fresh-air direct systems, increasing fresh air supply, improving air filtration, solving air humidification problems in winter and condensate from air conditioners, avoiding backflow in exhaust systems and guaranteeing pressure requirement of different building spaces.
