Capacity control
The compressor combination (DC inverter compressor + DC inverter compressor) allows smooth capacity control from
0.6-Ton to 30-Ton.
Realization of smooth capacity control
from 0.6-Ton to 30-Ton
Capacity control is possible smoothly with a DC inverter compressor.
The following graph shows the image of the operating combination of compressors in case of 30-Ton system.
In actual operation, the combination will be changed according to the operating condition, operating time amount and priority of
compressor, etc.
