What is the recommended action when determining the placement of air intake openings?

The recommended action when determining the placement of air intake openings is to avoid locations near exhausts. This is crucial for maintaining air quality and system efficiency. If air intake openings are positioned near exhaust vents, there is a risk of drawing in contaminated or stale air, which can negatively impact the performance of the HVAC system. Clean, fresh air is essential for optimal operation and to ensure that the system is circulating air effectively throughout the space it is meant to serve.

Proper placement of intake openings helps in maximizing airflow and ensuring a supply of fresh air. Locations that are too close to exhausts may not only impair performance but can also create potential safety hazards if combustion gases or other pollutants are unintentionally pulled into the intake system.

While considering factors like prevailing winds, spacing, and adjustability is important in HVAC design, the priority must always be the health and effectiveness of the indoor environment. Therefore, maintaining adequate separation between intake and exhaust openings is a foundational principle in HVAC design.
