The compressor combination (DC inverter compressor + constant-speed compressor) allows smooth capacity
control from 0.8 HP to 48 HP.
Realization of smooth capacity control from
0.8 HP to 48 HP
For the outdoor units of 8, 10, 12, 14 and 16 HP, a DC
inverter and a constant-speed compressor both are installed.
Correspondence to capacity control, which is difficult with
a constant-speed compressor, is possible smoothly with
a DC inverter. The performance difference at the time of
start of a constant-speed compressor also is eliminated.
