Depending on the manufacturer, a heat pump application that requires 6 tons of cooling will have a total system air flow requirement of approximately ________________ CFM.

In heat pump applications, the total system airflow requirement is typically calculated based on the cooling capacity of the system, which is often measured in tons. For a cooling capacity of 6 tons, the general rule of thumb is that each ton requires approximately 400 CFM (cubic feet per minute) of airflow. Therefore, for 6 tons of cooling, the calculation would be:

6 tons x 400 CFM/ton = 2,400 CFM.

Given this understanding, the total system airflow requirement for a 6-ton cooling application would generally fall between 2,700 CFM and 3,000 CFM to account for various factors such as duct size, design, and efficiency. Thus, the choice indicating 2,700 to 3,000 CFM aligns well with the practical requirements for such systems, making it the correct answer.

Other answers might suggest airflow amounts that either fall short or exceed the typical range needed for efficient operation, which could lead to performance issues and less effective temperature regulation in a heat pump system.
