Abstract
A separate-type air conditioner that can reduce the effect of voltage fluctuations in a commercial power supply (12) on a compressor (11), reduce material costs while maintaining vibrations of an outdoor unit (2) at low levels, and improve working efficiency during an assembly operation. The outdoor unit (2) includes a voltage correction circuit (14) to keep an output voltage to the compressor (11) constant (optimum) irrespective of the voltage fluctuations in the commercial power supply (12).
