<Heating>
(1) Nominal power input of outdoor unit
(2) Calculation of the average indoor temperature power input coefficient
Average indoor temp. power input coefficient (
= 0.8 × 36/(36 + 36 + 0.8 × 36/(36 + 36
= 0.80
(3) Coefficient of the partial load (CTi/CTo)
(4) Outdoor power input (PIo)
Maximum System Capacity (CTx = Total Indoor unit Capacity (CTi , so use the following formula
PIo = Outdoor unit Heating Nominal Power Input × Correction Coefficient of Indoor temperature × ƒ
= 5.48 × 0.8 × 0.94
= 4.12 kW
