överskottsluften

Överskottsluften, often translated as "surplus air" or "excess air," is a term used in ventilation and combustion processes. In the context of ventilation, it refers to the amount of air supplied to a space that exceeds the minimum required for occupant comfort, health, or process needs. This extra air can be introduced to provide improved air quality, dilute odors and pollutants more effectively, or to meet specific industrial requirements. However, excessive amounts of överskottsluften can lead to increased energy consumption for heating and cooling, as this additional air must also be conditioned to the desired temperature.

In combustion, överskottsluften is the amount of air supplied to a burner or furnace that is greater than the chemically perfect amount needed for complete combustion of the fuel. This surplus air ensures that all fuel is burned, minimizing the formation of incomplete combustion products like carbon monoxide. It also helps to control the flame temperature and can improve the efficiency of the combustion process by pushing the equilibrium towards complete oxidation. However, too much överskottsluften can lead to heat loss, as the hot combustion gases carry away more thermal energy up the chimney or exhaust. Therefore, optimizing the amount of överskottsluften is crucial for both ventilation and combustion efficiency and performance.
