Abstract

This chapter introduces the theoretical and experimental study for thermal plumes of kitchen appliances, as well as the methods to determine airflow rates for kitchen exhaust hoods. Convection plumes from an iron range, a chrome range, a gas range, and an induction griddle are analyzed under idling and cooking conditions. Exhaust airflow rate requirements to capture, contain, and remove effluent vary considerably depending on hood style, presence and size of side panels, cooking equipment, food, and cooking processes involved. The calculation methods of exhaust airflow rate are proposed such as face velocity methods, energy balance method, and convection load method.
