9-7. METHOD FOR OBTAINING ELECTRICAL CHARACTERISTICS WHEN A CAPACITY
AGREEMENT IS TO BE SIGNED WITH AN ELECTRIC POWER COMPANY
The electrical characteristics of connected indoor unit system for air conditioning systems, including the Power Multi series,
will depend on the arrangement of the indoor and outdoor units.
First read the data on the selected indoor and outdoor units and then use the following formulas to calculate the electrical
characteristics before applying for a capacity agreement with the local electric power company.
9-7-1. Obtaining the electrical characteristics of the Power Multi series system

(1) Procedure for obtaining total power consumption

Total power consumption of each indoor unit See the technical manual of each indoor unit.
Power consumption of outdoor unit*
Total power consumption of system
*The power consumption of the outdoor unit will vary depending on the total capacity of the selected indoor units.

(2) Method of obtaining total current

Total current through each indoor unit
Current through outdoor unit*
Total current through system
*The current through the outdoor unit will vary depending on the total capacity of the selected indoor units.

(3) Method of obtaining system power factor

Use the following formula and the total power and current obtained in parts 1 and 2 on the above tables to calculate the
system power factor.
System power factor =
9-7-2. Applying to an electric power company for power and total current
Calculations should be performed separately for heating and cooling employing the same methods; use the largest
resulting value in your application to the electric power company.
