2. Unit selection (with cooling load)
2.1 Indoor unit selection
Select the nearest load capacity indoor unit with given load after finding indoor and outdoor temperature using
indoor capacity table.
CAUTION: The described capacity may be different to each indoor unit according to combination. So the real
capacity should be calculated with outdoor unit capacity table.
2.2 Outdoor unit selection
The allowable combination is described on the indoor combination total capacity index table.
For the standard of the indoor unit and outdoor unit combination, select the nearest value that the total indoor unit
capacity index is less than a 130% outdoor unit combination capacity index.

2.3 Real function data
(1) Select the exact table according to outdoor unit model and combination rate using
outdoor unit capacity table. According to given indoor and outdoor temperature, find
outdoor unit capacity and power input using the table. Each indoor unit capacity (Power
input)is calculated as follows.
IUC=OUC × INX/TNX
IUC: Each indoor unit capacity (power input)
OUC: Outdoor unit capacity (power input)
INX: Each indoor unit capacity index
TNX: Total capacity index
(2) According to pipe length, change the indoor unit capacity. If the changed capacity is

smaller than load, change it to larger capacity indoor unit and repeat the selecting
progress.
