1. Unit selection (with cooling load)

1-1. Indoor unit selection

Select the nearest load capacity indoor unit with given load after finding indoor and outdoor temperature using indoor unit capacity table. (The indoor unit capacity should larger than given load.)

◆ 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.

1-2. Outdoor unit selection

The allowable combination is described on the indoor unit combination total capacity index table.

For the standard of indoor unit and outdoor unit combination, select the nearest value that the total indoor unit capacity index is less than a 100% outdoor unit combination capacity index.

1-3. 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 follow.

IUC=AUC x 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.
