1.4 Conditions and Method to Exclude Calculation for Specified Indoor Unit 261
Power Proportional Distribution (P.P.D.)
1.4 Conditions and Method to Exclude Calculation for Specified Indoor Unit
There is a case that a part of indoor units is desired to be excluded from calculation, such as corridor, hall, etc..
Typically, there are two ways as below.
1.4.1 The Power Consumption of Common-use Area can be Separated from Other Areas
1.4.2 The Power Consumption of Common-use Area is Distributed to Other Area
(In this case, it cannot uniformly be distributed to other indoor units. The power consumption of the common-use section
may be added to the specific indoor unit.)
Example:
When the power consumption is A=B=C=10kW and X=Y=Z=5kW, the calculation result total is 45kW, and the calculated
value of A, B and C is as follows:
The common-use section is distributed and power consumption is more than the actual one.
• Separating the system is required among the common-
use area, outdoor units for office, etc. and the power
source.
• Enter “No” in the column of electric energy distributing in
Address Table.
* In calculating the common-use power independently, it
is also possible to mount the watthour meter (with pulse
output) for common-use area.
• The power consumption of the common-use area is
distributed to the indoor unit in the office, etc. The
calculated value in the office, etc. is increased by the
value distributed from the common-use area.
• The wiring work method for the common-use area is
quite the same as that of the indoor unit in other offices,
etc.
* Enter “No” in the column of electric energy distributing
in Address Table.
