• Outdoor unit capacity saving
The power consumption is reduced by limiting the upper limit of the outdoor unit capacity for each
refrigerant system.
This has a reducing effect especially in the summer, winter and other times when the heat load is
high.
In addition, because the upper limit capacity of the outdoor unit is limited directly, it is a control
which easily exhibits an energy saving effect compared to rotation control. However, because the
outdoor unit does not operate above the limited capacity, there may be a loss of comfort, depend-
ing on the indoor heat load. (The operation capacity upper limit rate [%] of the outdoor unit is spec-
ified for each refrigerant system.)
