How many amps required to run air conditioning 20 tons 3 phase?

Answer 1

1 ton of air-con is defined as 3577 watts

Therefore 20 tons is 71.5 kW. On a 240 v 3-ph system the current for that is 100 amps, assuming a 240 v line-to-neutral voltage, equivalent to a phase-to-phase voltage of 415 v.

Answer 2

Somewhere on it, it will have a specification plate - that will include power and/or current drain. If it has only power, divide that by the supply voltage to get current. Otherwise, the weight of the thing is no clue as to power drain.

Answer 3

To do the proper electrical sizing for an air conditioner connection, watts are not needed. Watts are the product of amps times volts. The voltage needs to be stated for the correct insulation rating and the amperage needs to be stated to select the proper wire size.

Answer 4

Convert tons to watts and divide by the supply voltage. One ton of A/C is 822 watts, so 120 tons is 450 amps at 220 volts.

Answer 5

It depends on the type of it and what kind of house you live in, for example if you live in an apartment, it would cost you less. That's cuz of the air conditioner! <3 you question.

Answer 6

It depends on the EER (Energy Efficiency Ratio), which you did not provide. Please restate the question.

Answer 7

120 tons is a big system drawing 500-600 kilowatts, and it might be supplied at medium voltage (three-phase, more than 1000 volts), so the current cannot be estimated without more details.

Answer 8

The amperage is in direct relationship to the voltage of the unit. The voltage needs to be stated.

Answer 9

10 amps
