Divide the airflow in cubic feet per minute (CFM) by the cooling capacity in tons to find CFM per ton.
The CFM Per Ton Calculator determines the airflow required per ton of cooling capacity, a critical parameter in HVAC system design.
Proper airflow ensures efficient cooling and maintains comfort levels. This tool is particularly useful for sizing ducts, selecting air handlers, and verifying system performance in residential, commercial, or industrial setups.
Formula:
CFPT = CFM / C
| Variable | Definition | Units |
|---|---|---|
| CFPT | CFM per ton | Cubic feet per minute per ton |
| CFM | Airflow | Cubic feet per minute (CFM) |
| C | Cooling capacity | Tons |
Solved Calculations:
Example 1: Calculate CFM per ton for a system delivering 1200 CFM with 3 tons of cooling capacity
| Step | Value | Explanation |
|---|---|---|
| Airflow (CFM) | 1200 CFM | Measured airflow |
| Cooling Capacity (C) | 3 tons | System’s cooling capacity |
| Formula Application | 1200 / 3 | Divide airflow by cooling capacity |
| CFM per Ton (CFPT) | 400 CFM/ton | Final result |
Example 2: Calculate CFM per ton for a 2.5-ton system with 1000 CFM airflow
| Step | Value | Explanation |
|---|---|---|
| Airflow (CFM) | 1000 CFM | Measured airflow |
| Cooling Capacity (C) | 2.5 tons | System’s cooling capacity |
| Formula Application | 1000 / 2.5 | Divide airflow by cooling capacity |
| CFM per Ton (CFPT) | 400 CFM/ton | Final result |
What is the CFM Per Ton Calculator?
The CFM Per Ton Calculator is a specialized tool that is used in HVAC (Heating, Ventilation, and Air Conditioning) systems to calculate the airflow in cubic feet per minute (CFM) required per ton of cooling capacity. It ensures that air conditioning systems deliver optimal performance by maintaining the correct airflow.
This calculator takes inputs like cooling capacity (in tons) and desired CFM per ton ratio, then computes the total airflow. For example, the standard guideline is approximately 400 CFM per ton of cooling, though this may vary based on specific system requirements and environmental conditions.
Using this tool helps HVAC professionals design and troubleshoot systems, ensuring adequate cooling and energy efficiency. It is ideal for determining airflow for residential, commercial, or industrial spaces.
Final Words:
Ultimately, the CFM Per Ton Calculator is an indispensable resource for accurate airflow calculations, enabling HVAC professionals and users to optimize cooling systems for efficiency and comfort.
