(c) Calculation of total operation characteristics
Since the operation characteristics of series Multi depend on combination of indoor unit, calculate the total operation charac-
teristics of the system by using the formulas below according to specifications of each indoor unit or outdoor unit.
1)Total power input
Total power input (kW) = Power input of outdoor unit + ∑ (Power input of indoor unit)
2)Total running current
Total running current (A) = Running current of outdoor unit + [∑ (Running current of indoor unit) × 2/3]
3)Total power factor
Total power factor (%) = [Total power input (W) / √
—
3 × Total running current (A) × Power source] × 100
Total operation characteristics = Operation characteristic value of outdoor unit + Operation characteristic value of indoor unit
[Example]
(3) Operation chart
The Multi series is a system that allows for different models and capacities of indoor units to be combined so the individual
operating characteristics of the indoor and outdoor are provided. Use the procedure shown in Item (c) to calculate the combined
operating characteristics.
