3) Select preliminary outdoor units
Ô Before selecting outdoor units, decide the permissible combination rates for indoor and outdoor unit.
➊ Determining permissible combination rates for indoor and outdoor units: Below 110%
❷ Calculate the sum of total capacity of the selected indoor units: 52.9kW (Refer to the table below)
52.9kW = [3.6kW + 7.1kW + 5.6kW + 7.1kW + 11.2kW + 7.1kW + 11.2kW]
❸ Select outdoor units
❹ Calculating actual combination rates of indoor and outdoor units

❈ Therefore, as 52.9kW/1.1 should meet outdoor unit capacity and less ( 52.9 kW/1.1 ≤ outdoor unit capacity), cooling
capacity of outdoor unit should be larger than 48.1kW.
Hence, select the outdoor unit RVXVHT180GE(refer to the table below).
