Select outdoor units to match the total capacity of indoor units preliminarily
(Conrm the rated capacity ratio of indoor and outdoor units, the number of
connectable indoor units within limit)
Conrm if the capacity of outdoor units selected on previous process is listed
in Space saving combination or Energy efciency combination.
System capacity = Compensated capacity of outdoor units
END
Calculate actual capacity of each indoor unit by dividing
system capacity proportionally (Refer to 2-3-2)
Select Space saving combination
or Energy efciency combination.
System capacity = Total capacity of
indoor units at design temperature
Change to a larger
capacity of outdoor units
Actual capacity of indoor unit =
Capacity of indoor unit at design
temperature
Select outdoor units in the Space
saving combination.
A
Is the capacity of outdoor units selected listed in
Energy efciency combination?
Total capacity of indoor units at design
temperature ≥ Compensated capacity of
outdoor units
Actual capacity of indoor unit ≥ Heat load
