Compressor – Module capacity control
ƒ Purpose
Improve efficiency through appropriate capacity distribution among units.
Maximize the lifespan through equalization of the duration of operation among
outdoor units.
ƒ Concept
The duration of operation is equally distributed among outdoor units through rotational operation of the outdoor units.
The duration of oper
ation is equally distributed among the compressors on indoor units through rotational operation of the com-
pressors.
The operation efficiency is optimized by setting
the operation capacity for each outdoor unit according to the outdoor unit capacity
ratio.
ƒ Control specifications in detail
It shall be operated according to priority to prevent operational ti
me from being concentrated on any of outdoor units during the
operation of Hysteresis. Operating outdoor unit can be circulated in case only some ou
tdoor units are operated under partial load in
case of operation by priority. Driving priority can be changed in case that oil recovery and entire outd
oor units are off.
