Laminar diffusers are often employed in cleanrooms, hospital operating rooms, laboratories, and similar other spaces where high level of cleanliness is desired. These air supply outlets (diffusers) are designed to provide unidirectional flow–often referred as...

This is a follow-up to the previous post on airflow patterns in hospital operating room (OR). Previous Computational Fluid Dynamics (CFD) study of a legacy HVAC design of a hospital OR indicated that the supply airflow rates or air change rates (ach) have a little...

In displacement ventilation systems, as opposed to the traditional overhead supply mixing ventilation systems, cold air which is supplied at low velocity near the floor captures sensible heat from the space, and rises due to buoyancy, and thus, creates a stratified...

The purpose of laboratory ventiliation systems is to minimize the risk of chemical exposure and fire hazard, as well as facilitate odor removal by reducing the contaminant concentration to safe level while simultaneously maintaining thermally acceptable environment...
