The term in question describes a tool or method used to convert a measurement of airflow, expressed in cubic feet per minute (CFM), into a unit of cooling capacity, expressed in tons. For example, an HVAC system designer might need to determine the required cooling capacity in tons for a room that requires a specific airflow rate of, say, 600 CFM, to maintain a desired temperature.
Accurate conversion between airflow and cooling capacity is critical in numerous applications. It enables effective HVAC system design, ensuring appropriate sizing for optimal performance and energy efficiency. Historically, these calculations were performed manually using established formulas and charts. The availability of automated tools streamlines this process, reducing the potential for human error and saving time.
