An instrument used to determine the number of times the total volume of air in a defined space is replaced over a specific time period, typically an hour. For example, a reading of 2.0 signifies the complete replacement of the air volume twice within one hour.
Accurate measurement of air turnover is crucial for maintaining acceptable indoor air quality, managing energy consumption related to ventilation, and controlling the spread of airborne contaminants. Historically, these calculations were performed manually, leading to potential inaccuracies and inefficiencies. Current methodologies often incorporate advanced sensors and algorithms to provide more precise and reliable data.
