depends a lot on operating conditions such as ambient temperature, refrigerant
pressure, Energy Efficiency Ratio (EER) etc. for instance, if EER is 6, then
input power for 2 Tons Air conditioner is 24000BTU/ 6 = 4000 watts.. <br />
If this is a 230 volt system, then air conditioner load current would be = 4000/(230x.95)
= 18.5 A</span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0in;">
<span style="font-family: "Arial","sans-serif";">For More detail…Check
the Air conditioner Name plate rating.<br />
Another similar rating is Coefficient of power (COP) which is the output power
in watts divided by input power, so with a COP = 1.8, for instance, input power
for 2 Tons Air conditioner <span style="mso-spacerun: yes;"> </span>is 7032W / 1.8
= 3906 watts. Now you can find current by using the above method which is equal
to 18A approx.</span></div>
