A definite answer can not be given with this data. This is because the power factor is not given.





If the current you seek is only for the watts portion of the total KVA of the machine, the current will be





I = W / E



I = 155 / 220



I = 0.7045... amperes





But, all AC motors require some reactive current. Generally, the power factor of modern motors (compressor and fans in your case) have a power factor greater than 0.85. However, using 0,85 as an example, the current would then be





I = (W / E) / 0.85



I = (155 / 220) / 0.85



I =( 0.7045...) / 0.85



I = 0.8288... amperes

If you don't know the power factor of the machine, you'll need to measure current.

watts = Volts x amps x power factor.

You may take 0.8 as a general PF, so you can now form a rough idea of current required.

Amps = watts / volts x 0.8.

PS.

155 / 220 x 0.8 = 155 / 176

= 0.88 amp

P=IV



P/V=I



155/220=I????__



155/200=.7045

P = I*V



so I = P/V



so I = 0.70 A
