What is the minimum volume of airflow in CFM for a domestic 2-ton air conditioner?

  1. 750 cfm

  2. 400 cfm

  3. 600 cfm

  4. 800 cfm

The correct answer is: 800 cfm

The minimum volume of airflow for a domestic 2-ton air conditioner is typically calculated based on the guideline that each ton of cooling requires approximately 400 CFM of airflow. For a 2-ton system, this would equate to a minimum of around 800 CFM. This figure is important because having adequate airflow is crucial for the efficient operation of an air conditioning system. Insufficient airflow can lead to inadequate cooling, increased energy consumption, and potential damage to the system. The 800 CFM represents the minimum threshold needed to adequately transfer heat away from the living space being cooled. Understanding these requirements is essential for gas fitters and HVAC technicians to ensure proper installation and operation of air conditioning systems. Proper airflow maximizes energy efficiency and extends the longevity of the equipment, making it a key detail in system specifications.
