1 ton - 0.7kw 1.5ton. - 1.3 kw 2 ton - 1.67
Formula. 1.032x220x3.5x0.9 x1000 =0.7

Answer / divyang dabhi

1 Ton a.c = 1350 watts. 1.5 * 1350 = 2025 watts then amp= w/v *of = 2025/230*0.8 = 11 amp

Answer / arvind

it is not 1.5 watt it should be kw by mistake it is written w at last

Answer / kuldeep kathpal

As we know 1TR=3.5172KW then 1.5TR=5.2758KW
and P(KW)=(1.732*415*.8*I)/1000 For three phase
then I=5.2758*1000/1.732*415*.8=9.174A

So. For three phase supply 1.5TR AC will consumes
9.174Amperes

Similarly For single phase I=5.2758*1000/240*.8

Answer / ariel

COP = cooling capacity / compressor power; COP = 2.5 for
typical Direct Expansion AC units. Substitute the COP
value, 2.5 = Ton cooling/ kWcomp; or kWcomp = Ton
cooling / 2.5. Multiply Ton by 3.517 to convert it into kW
cooling. kWcomp = (3.517 / 2.5) x Ton; kWcomp = 1.4 x
Ton. This kWcomp is approximately equal to the system kW
based on AC units catalogs. MCA = (1.4/0.8 x Ton) / Voltage-
phase or MCA = 1.75 x Ton / Voltage-phase

Answer / argee

Answer no 5 appears spot on.

Actually, the terminology of marking airconditioners units as "Tons" is basically incorrect.

I wish we could do away with it and instead have the BTU (british thermal units) to rate the airconditioners in India.
More accurate, and less prone to misleading advertisements.

Great going Randy. Your answer refreshed by school physics class today!

Answer / randy

BASICALLY, 1 TON = 12,000 BTU
1 WATT = 3.412 BTU
THEREFORE: 1 TON = 3,516 WATTS = 4.713Hp

CURRENT (Amp) I = Power (Watts) P /Voltage
(volts) V

I = 3,516Watts/240Volts
I = 14.65Amperes

The ans: a)P=3,516Watts
b)I=14.65Amperes

Answer / elangkumanan

1 ton =746watt
1 watt=1000kw
1 ton starting current 10A after running current 6A
POWER=V*I
W=230*5=1150
W =1150
----- =1.150W
1000
