Ventilation with exhaust fan is the most basic and fundamental requirement for every single building. With active ventilation system, it introduces fresh air into indoor and diluting or displacing hot indoor air and pollutants.
An exhaust hood system consists of three main components: a skirt or capture panel to contain the rising gases (also known as the “effluent plume”), one or more grease filters, and a fan or tangential blower for forced ventilation.
Liquid evaporates by shedding molecules into the air, changing from a liquid state to a gas. As they become suspended in the air, the molecules draw some of the heat from the hotter air, cooling it down as the water and air find equilibrium.
