2) 3 Phase models
a) Total power consumption
Total power consumption (kW) = Power consumption of outdoor unit +
∑
(Power consumption of indoor unit)
b) Total running current
Total running current (A) = Running current of outdoor unit + [
∑
(Running current of indoor unit) × 1/3]
c) Total power factor
Total power factor (%) = [Total power consumption (W) / 3 × Total running current (A) × Power source] × 100
Total operation characteristics = Operation characteristic value of outdoor unit + Operation characteristic value of indoor unit
