New Perspectives on Kitchen Ventilation

23 May 2019 | New Perspectives on Kitchen Ventilation

Cooking is a major source of indoor contaminants, including moisture, odors and particles. Proper venting of cooking activities is an essential part of providing acceptable indoor air quality in homes. This webinar will discuss kitchen venting, including measurements of contaminants that are emitted from cooking, discussions of kitchen exhaust ventilation system performance and guidance on best practices for kitchen ventilation.

 

Measured Pollutant Performance of Island Overhead Kitchen Exhaust

Cooking is one of the most substantial sources of indoor air pollution in most residences.  This is mitigated most often by exhaust devices located near cooking surfaces.  In this study, we measured the efficacy of one type of kitchen ventilation device: an island overhead kitchen exhaust.  Laboratory tests using tracer gas capture were performed on a full-scale mock-up of a kitchen with a cooktop in an island. The results show that the Capture Efficiency (CE) varies greatly from about 10% to nearly 100%.
