Airborne infection prevention: comparison between mixing and displacement ventilation

Lupe

Usually,  displacement  ventilation  is  characterized  by  a  higher  ventilation  effectiveness  than  mixing  ventilation.  Is  it  therefore  a  better  prevention  of  airborne  infection? More information on our blog:
