(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 previous page to calculate the
system power factor.
System power factor =
(Total system power consumption)
(Total system current x voltage)

10-6-2. 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.
10-6. 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 MULTI-S
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.
