What type of device is a range hood installed in the kitchen?

A range hood is classified as a local exhaust device because its primary function is to capture and remove airborne contaminants generated during cooking, such as smoke, steam, grease, and odors. Unlike central air conditioning, which provides widespread temperature regulation throughout a space, a range hood specifically targets the localized area above the cooking surface, effectively improving indoor air quality by venting these pollutants outside or through a filtration system.

By functioning as a local exhaust device, a range hood helps prevent the accumulation of harmful substances in the kitchen environment. It plays a crucial role in maintaining a safe and comfortable cooking atmosphere, distinguishing it from heating appliances, which primarily focus on temperature elevation or refrigeration units that preserve food by cooling. The range hood's design and operation are essential components for ensuring effective ventilation in a kitchen setup.
