Capacity control
The compressor combination (DC inverter comp constant-speed compressor) allows smooth capacity control from
0.6-Ton to 24-Ton.

Capacity control is possible smoothly with a DC
inverter compressor. The right graph shows the
image of the operating combination of compres-
sors in case of 24-Ton system. In actual operation,
the combination will be changed by operating
condition, operating time amount, priority of com-
pressor and so on.
