For a domestic 2 ton air conditioner, what is the minimum volume of airflow (cfm) required?

For a domestic 2-ton air conditioner, the minimum volume of airflow required is typically calculated using a general rule of thumb that suggests 400 to 450 cubic feet per minute (cfm) per ton of cooling capacity. Since 2 tons of cooling capacity equates to around 800 to 900 cfm, a value of 800 cfm is considered a reasonable minimum for ensuring efficient operation and adequate cooling.

This volume of airflow allows the air conditioning system to effectively circulate cool air throughout the space, providing comfort and maintaining desired indoor temperatures. Ensuring that the system operates within this airflow range also helps in sustaining energy efficiency and optimizing performance.

The other values may not adequately meet the cooling needs or performance efficiency for a 2-ton system, leading to potential issues such as insufficient cooling or increased energy costs. Hence, the value of 800 cfm aligns with industry standards for a two-ton unit, making it the appropriate choice.
