Makeup air is commonly deposited directly into which part of the HVAC system?

Makeup air is commonly deposited directly into the fresh air intake of an HVAC system. This part of the system is designed to introduce fresh outdoor air into the building while balancing any air that is exhausted from the interior. By adding makeup air at the fresh air intake, the HVAC system can maintain proper indoor air quality and pressure, especially in situations where exhaust systems have removed a significant amount of air from the space.

The function of the fresh air intake is to ensure that the overall system can replenish the air that is lost through exhaust processes, which might include cooking, bathroom ventilation, or any other activities that expel indoor air. By allowing makeup air in at this stage, the system can efficiently mix this fresh air with the conditioned air, ensuring that the indoor environment remains comfortable and healthy for occupants.
