Capture Efficiency of Range Hoods, an Industrial Perspective

While the development of a standardized capture efficiency metric for rating the performance of residential kitchen exhaust systems has received slightly less media coverage than this year’s US presidential race, it will arguably have a greater long-term effect on our species’ quality of life. This presentation provides an overview of a ventilation product manufacturer’s experience with conducting capture efficiency tests using two methods, shadowgraph and tracer gas, under various conditions and will highlight lessons learned along the way.
