Enter the tons of refrigeration, voltage, efficiency, and power factor into the calculator to determine the electrical current in amps. This calculator helps in converting the cooling capacity in tons to the electrical current required for an air conditioning or refrigeration system.
Tons to Amps Formula
The following formula is used to calculate the electrical current in amps from tons of refrigeration.
I = (TR * 3516.85284207) / (V * E * PF)
Variables:
- I is the electrical current (amps)
- TR is the tons of refrigeration
- V is the voltage (volts)
- E is the efficiency (as a decimal)
- PF is the power factor (as a decimal)
To calculate the electrical current in amps, multiply the tons of refrigeration by 3516.85284207, then divide the result by the product of voltage, efficiency, and power factor.
What is Tons of Refrigeration?
Tons of refrigeration (TR) is a unit of power used in some countries to describe the cooling capacity of air conditioning systems. One ton of refrigeration is approximately equal to the cooling power of one ton of ice melting in a 24-hour period. It is equivalent to 12,000 BTU per hour or 3516.85284207 watts.
How to Calculate Amps from Tons of Refrigeration?
The following steps outline how to calculate the electrical current in amps from tons of refrigeration.
- First, determine the tons of refrigeration (TR).
- Next, determine the voltage (V) in volts.
- Next, determine the efficiency (E) as a decimal.
- Next, determine the power factor (PF) as a decimal.
- Next, gather the formula from above = I = (TR * 3516.85284207) / (V * E * PF).
- Finally, calculate the electrical current (I) in amps.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
tons of refrigeration (TR) = 5 tons
voltage (V) = 240 volts
efficiency (E) = 0.95
power factor (PF) = 0.8
