1. What is the CFM to Tonnage Formula?

The CFM to Tonnage formula converts airflow (CFM) to cooling capacity (tonnage) for air conditioning systems. One ton of cooling equals 400 CFM of airflow.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — Tonnage (tons)
• \( CFM \) — Cubic Feet Per Minute (ft³/min)

Explanation: This formula provides a direct conversion from airflow measurement to cooling capacity measurement.

3. Importance of Tonnage Calculation

Details: Proper tonnage calculation is essential for sizing air conditioning systems, ensuring adequate cooling capacity, and optimizing energy efficiency.

4. Using the Calculator

Tips: Enter CFM value in cubic feet per minute. The value must be greater than 0 for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is 400 CFM equal to 1 ton?
A: This is a standard industry conversion based on the amount of heat removal required to melt one ton of ice in 24 hours.

Q2: Is this conversion accurate for all AC systems?
A: While 400 CFM per ton is a general rule, actual requirements may vary based on specific system design and environmental conditions.

Q3: When should I use this calculation?
A: Use this when sizing new AC systems, evaluating existing system performance, or troubleshooting airflow issues.

Q4: Are there limitations to this formula?
A: This is a simplified conversion and may not account for factors like humidity, altitude, or specific system efficiencies.

Q5: Can this be used for heating systems as well?
A: This formula is primarily for cooling capacity calculation. Heating systems use different metrics and calculations.
