(c) Calculation of total operation characteristics
Since the operation characteristics of V Multi system depend on combination of indoor unit, calculate the total operation characteristics
of the system by using the formulas below according to speciations of each indoor unit or outdoor unit.
1) 1 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)
c) Total power factor
Total power factor (%) = [Total power consumption (W) / Total running current (A)
s
Power source]

Total operation characteristics = Operation characteristic value of outdoor unit + Operation characteristic value of indoor unit
[Example]
(Conditions) Operation Voltage ········ Indoor unit: 220 V, 50 Hz
Outdoor unit: 220 V, 50 Hz
Operation mode ··········· Cooling and Heating
Unit······························· Outdoor unit: FDC140VNX × 1 unit
Indoor unit: FDT71VF × 2 units

Total running current (A)
(Cooling) 17.6 + (0.40 × 2) = 18.4
(Heating) 17.6 + (0.40 × 2) = 18.4

Total power factor (%)
(Cooling) × 100 = 99 %
(Heating) × 100 = 99 %
