Heater & A/C

9-3 Heater & A/C system: A/C compressor
Electric motor driven type of A/C compressor has been introduced. Inverter is integrated and it is controlled by serial
communication with A/C control unit.
It receives DC 330V directly from the battery pack, transform it to AC 330V by integrated inverter, then drive the motor
for compressor.
The inverter is cooled by the refrigerant, it is unnecessary to introduce extra cooling device such as cooling water.
Since the compressor is driven by the electric motor, it helps to save energy because compressor revolution is
controlled as minimally as possible.
The A/C compressor requires the special new oil for the lubrication, named as (MA68EV) which has high insulation
performance.
Although the A/C compressor oil for petrol powered “ i “ could not be used for i-MiEV, same A/C gas as HFC134a can
be used for i-MiEV.
