What is the function of the Make Up Air Point in ventilation procedures?

The Make Up Air Point plays a crucial role in ventilation systems by introducing fresh air into an area. This is particularly important in settings where air is being exhausted, such as during the operation of HVAC systems that remove stale or conditioned air from a space. By allowing fresh air to enter, the Make Up Air Point helps maintain balanced air pressure within the environment, ensuring that there is enough oxygen available for occupants and that indoor air quality remains high. This fresh air can mitigate issues like discomfort, odors, and pollutants, contributing to a healthier indoor atmosphere.

Introducing fresh air is essential for overall ventilation efficiency, as it compensates for the air being expelled, thus preventing negative pressure scenarios that could lead to infiltration of unconditioned air from unwanted areas or back draft in exhaust systems.
