Compared with fixed frequency type AC:
1. when reach the set temp, the inverter AC compressor will running at a low frequency. However the fixed frequency AC always stop and start continually, this will cause big power consumption、room temp temperature fluctuation.
2. inverter AC can running at high frequency within the shortest time, this can make cooling or heating rapidly. After reach the set temp, the running frequency will goes down, in this condition the unit is more quiet and power saving.
