What is the process of supplying or removing air from a space referred to as?

The process of supplying or removing air from a space is referred to as ventilation. This term encompasses the systematic introduction of fresh air into an indoor environment, as well as the expulsion of contaminated or stale air from the space. Proper ventilation is crucial for maintaining indoor air quality, controlling temperature, and ensuring comfort for occupants. It helps to dilute indoor pollutants, provide adequate oxygen levels, and manage moisture levels, contributing to a healthier indoor environment.

Air circulation generally refers to the movement of air within a space, which may or may not involve bringing in fresh air or exhausting stale air. Air exchange specifically describes the trade-off between incoming and outgoing air but is not the widely accepted term used in standards and guidelines. Temperature control, on the other hand, deals primarily with regulating the thermal comfort of a space rather than specifically focusing on the movement and quality of air. Therefore, ventilation is the most accurate term for the process in question.
