(1) Rated power input of outdoor unit
5.48 kW (Nominal)
0.94
0.80
(2) Calculation of the average indoor temperature power input coefficient
Coefficient of the outdoor unit for indoor unit 1 (Outdoor temp. 2 °CW.B., Indoor temp. 25 °CD.B.)
Maximum System Capacity (CTx) = Total Indoor unit Capacity (CTi), so use the following formula
PIo = Outdoor unit Heating Rated Power Input × Correction Coefficient of Indoor temperature × (CTi/CTo)
= 5.48 × 0.8 × 0.94
= 4.12 kW
0.80
Coefficient of the outdoor unit for indoor unit 2 (Outdoor temp. 2 °CW.B., Indoor temp. 25 °CD.B.)
= 0.8 × 36/(36 + 36) + 0.8 × 36/(36 + 36)
= 0.80
