Ton to Amps Calculator

Convert refrigeration capacity in tons to electrical current in amps. This calculator helps determine the electrical requirements for AC or refrigeration equipment based on its cooling capacity.

Input Parameters

Seasonal Energy Efficiency Ratio (SEER) or Energy Efficiency Ratio (EER) - typical values: 10-24

Calculation Results

Calculation Formula

Power (W) = (Cooling Capacity × 12,000) / SEER

Current (A) = Power (W) / (Voltage × Power Factor)

Where:
Cooling Capacity = Refrigeration capacity in tons
SEER = Seasonal Energy Efficiency Ratio
Voltage = Operating voltage in volts
Power Factor = Assuming 0.9 for AC motors

Cooling Capacity (BTU/h):

0

Power Consumption (W):

0

Current Draw (A):

0

Ton to Amps Calculator Calculator Usage Guide

Learn how to use the Ton to Amps Calculator and understand the relationship between refrigeration capacity and electrical requirements.

How to Use This Calculator

  1. Enter the cooling capacity of your equipment in tons (e.g., 2.5 tons).
  2. Specify the SEER (for cooling) or EER (for heating) rating of your equipment. Higher SEER/EER values indicate greater energy efficiency and result in lower current draw. Typical values range from 10 to 24.
  3. Select the operating voltage of your equipment (120V, 240V, or 480V).
  4. Click the "Calculate" button to compute the electrical requirements.

Understanding the Results

The calculator provides three key measurements:

  • Cooling Capacity (BTU/h): The total heat removal capacity of the system in British Thermal Units per hour.
  • Power Consumption (Watts): The electrical power consumed by the system to achieve the cooling capacity.
  • Current Draw (Amps): The electrical current drawn by the system from the power source.

Principle of Calculation

The calculator uses the following formulas:

Power (W) = (Cooling Capacity × 12,000) / SEER

Current (A) = Power (W) / (Voltage × Power Factor)

Where the power factor is assumed to be 0.9 for typical AC motors and compressors.

Practical Applications

This calculator helps you:

  • Size electrical service panels and circuits appropriately for AC equipment
  • Verify that your electrical system can handle the load of refrigeration equipment
  • Compare energy efficiency of different equipment models
  • Plan for appropriate circuit breakers and conductors

Important Notes

Remember that these are approximate calculations. Actual electrical requirements may vary based on specific equipment design, operating conditions, and additional components in the system. For critical applications, consult equipment specifications or a qualified electrician.
