Outside Air is abbreviated as which of the following?

Explanation:
Understanding how Outside Air is referred to in HVAC terminology helps you match the term to its common abbreviation. In ventilation design and commissioning work, the air drawn from outdoors for space conditioning is typically labeled OA. That makes Outside Air the term that corresponds to the standard abbreviation OA most directly. While “Outdoor Air” is a very close wording, the familiar, formal term used in documentation that maps to the OA abbreviation is Outside Air. The other options aren’t standard terms in this context.
