Air distribution design for infectious isolation wards

Suggestions about air distribution design for infectious isolation wards were almost put forwards for single ward at abroad. However, the isolation wards are of more than one bed in order to reduce initial costs and usecost of the wards in most countries and areas. Studies the influence of different air distribution modes on the diffusion of patient contaminants by the method combined experiment with numerical simulation, and gives some suggestions about how to design the air distribution of infectious isolation wards properly.
