In order to further improve inverter performance, control is
switched between PWM control at low operation speeds, and
PAM control at high operation speeds, making the most
effective use of power.
The compressor operation frequency varies.
The indoor fan operates with 1/f fluctuation.
The compressor operates at a low operating frequency.
