8. CAPACITY TABLES
3. Power input of outdoor unit
<Cooling>
(1) Nominal power input of outdoor unit
(2) Calculation of the average indoor temperature power input coefficient
Average indoor temp. power input coefficient (
= 1.09 × 36/(36 + 36 + 1.03 × 36/(36 + 36
= 1.06
(3) No need to consider Coefficient of the partial load (CTi/CTo)
(4) Outdoor power input (PIo)
Maximum System Capacity (CTx = Total Outdoor unit Capacity (CTo , so use the following formula
PIo = Outdoor unit Cooling Nominal Power Input × Correction Coefficient of Indoor temperature
= 4.55 × 1.06
= 4.82 kW
