Select outdoor unit to match the total capacity of indoor units preliminarily
(Conrm the rated capacity ratio of indoor and outdoor unit, the number of
connectable indoor units within limit)
Conrm if the capacity of outdoor unit.
System capacity = Compensated capacity of outdoor unit
END
Calculate actual capacity of each indoor unit by dividing
system capacity proportionally (Refer to 3-2)
System capacity = Total capacity of
indoor units at design temperature
Change to a larger
capacity of outdoor unit
Actual capacity of indoor unit =
Capacity of indoor unit at design
temperature
