Notes (1) This packaged air-conditioner is manufactured and tested in conformity with the following standard.
JIS B8616 “UNITARY AIR-CONDITIONERS”
(2) The values shown in the above table are common to both cooling and heating operations.
(c) Calculation of total operation characteristics
Since the operation characteristics of series Multi-KXR depend on combination of indoor unit, calculate the total operation
characteristics 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) × 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
