摘要
本文首先分析了ICU的特点和全新风运行能降低感染风险的原因，据此提出了符合ICU特点的间断回风策略——用临界温度来切换全新风运行与回风（最小新风）运行两种工况。然后对我国不同气候条件下6个代表城市的临界温度和实施效果进行了计算，结果表明不同城市采取间断回风运行能有10％~30％的节能效果，其中昆明和北京冬夏季节能效果都比较明显。
This paper firstly analyzes the characteristics of ICU and the reasons why all fresh air running can reduce the risk of infection in ICU. Then we proposed a discontinuous return air operating strategy accordingly - to switch the two working conditions （all fresh air and minimum fresh air） with the critical temperature. Through theoretical calculation under six different climate, we proved that it can guarantee indoor air quality and reduce the energy consumption by 10% -30% among which the energy-saving effect in Kunming and Beijing are relatively high both in winter and summer.
