Ersättningsluft
Ersättningsluft, often translated as make-up air or replacement air, refers to the air introduced into a building to compensate for air that has been intentionally or unintentionally removed. This removal can occur through various building systems such as exhaust fans in kitchens, bathrooms, laboratories, or industrial processes. Without adequate replacement air, these exhaust systems can create negative pressure within the building.
Negative pressure can lead to several undesirable consequences. It can cause drafts as unconditioned outside air
