9-6. 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 char-
acteristics before applying for a capacity agreement with the local electric power company.
9-6-1. Obtaining the electrical characteristics of a CITY MULTI-S series system
(1) Procedure for obtaining total power consumption
Total power consumption of each indoor unit See the technical manual of each indoor unit
*1 power consumption of outdoor unit
Total power consumption of system
*1 Please note that 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
*2 current through outdoor unit
Total current through system
*2 Please note that the
(3) Method of obtaining system power factor
Use the following formula and the total power and current obtained in parts 1 and 2 in the above table to calculate the system
power factor.
System power factor =
9-6-2. 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.
