法国里昂大学Jack D.Joubert教授综合了常规暖通空调系统和单向流系统两者最好的特点,发展成一种新系统。它在法国被称为Joubert系统。这种系统在运行中应达到:能源得到有效利用,安静和保证快速清除细菌污染,在30分钟内达到自净效率高于99％,并且在外科手术部位保证细菌污染率尽可能低。为此,他用采样器(Joubert细菌收集器)来采集空气中细菌本底数据(图1)。这个采样器类似安德森(Andersen)6级筛式采样器,所不同的是它只有3级。安德森采样器采集的空气流量为28.3升/分,Joubert细菌收集器采集的空气流量为500
Professor Jack D.Joubert of the University of Lyon, France, combined the best features of conventional HVAC systems and unidirectional flow systems into a new system. It is called the Joubert system in France. This system should be in operation: energy is effectively used, quiet and guaranteed to quickly remove bacterial contamination, achieve self-purification efficiency of more than 99% in 30 minutes, and ensure that the bacterial contamination rate is as low as possible at the surgical site. To do this, he used a sampler (Joubert bacteria collector) to collect bacterial background data in the air (Figure 1). This sampler is similar to Andersen’s 6-stage screener, except that it has only 3 stages. The Anderson sampler collected 28.3 liters/minute air flow, and the Joubert bacteria collector collected 500 air flow.
