3. Power input of outdoor unit
(1) Rated power input of outdoor unit
4.55 kW (Nominal)
-
1.09
(2) Calculation of the average indoor temperature power input coefficient
Coefficient of the outdoor unit for indoor unit 1 (Outdoor temp. 37 °CD.B., Indoor temp. 20 °CW.B.)
Maximum System Capacity (CTx) = Total Outdoor unit Capacity (CTo), so use the following formula
PIo = Outdoor unit Cooling Rated Power Input × Correction Coefficient of Indoor temperature
=4.55 × 1.06
= 4.82 kW
1.03
Coefficient of the outdoor unit for indoor unit 2 (Outdoor temp. 37 °CD.B., Indoor temp. 17.8 °CW.B.)
= 1.09 × 36/(36 + 36) + 1.03 × 36/(36 + 36)
= 1.06
