2. Features of W-2WAY ECO-i SYSTEM
Capacity control
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 0.8HP to 48HP
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 48HP system. In actual operation,
the combination will be changed by operating
condition, operating time amount, priority of com-
pressor and so on.
