10 Calculating air conditioner distribution
The Intelligent Controller calculates energy (electricity and gas) distribution ratios utilizing the
accumulated working time (T/S ON/OFF) or the capacity value of the indoor unit.
* T/S: Thermostat
10.1 Calculating simple distribution
Parameters as listed below are used to calculate simple distribution:
1
RHHi : accumulated operation time for indoor unit i (High fan speed)
2
RHi : accumulated operation time for indoor unit i (Medium fan speed)
3
RLi : accumulated operation time for indoor unit i (Low fan speed)
4
SHHi : T/S ON accumulated time for indoor unit i (High fan speed)
5
SHi : T/S ON accumulated time for indoor unit i (Medium fan speed)
6
SLi : T/S ON accumulated time for indoor unit i (Low fan speed)
7
Pi : Capacity of indoor unit i (in kW)
8
k : Weighing factor for power consumptions as T/S ON and OFF
9
aHH : Weighing factor for High fan speed
bk
aH : Weighing factor for Medium fan speed
bl
aL : Weighing factor for Low fan speed
* Accumulated operation time = T/S ON accumulated time + T/S OFF accumulated time
Index of indoor unit i power/gas consumptions is calculated.
Here, “TEi” and TGi” denotes the power and gas consumption indexes of the indoor unit i,
respectively.
When “Object of power distribution calculation” is “T/S ON + OFF time”:
The power consumption index is calculated using “Accumulated operation time” and “T/S ON
accumulated time”; the gas consumption index using “T/S ON accumulated time”
•
For GHP:
TEi = (RHHi x aHH + RHi x aH + RLi x aL) x Pi Formula 1
TGi = (SHHi x aHH + SHi x aH + SLi x aL) x Pi Formula 2
•
For PAC:
TEi = { (RHHi x aHH + RHi x aH + RLi x aL) /k +
(SHHi x aHH + SHi x aH + SLi x aL)} x Pi Formula 3
TGi = 0
When “Object of power distribution calculation” is “T/S ON time”:
Both the power and gas consumption indexes are calculated using “T/S ON accumulated time”.
•
For GHP:
TEi = (SHHi x aHH + SHi x aH + SLi x aL) x Pi
TGi = (SHHi x aHH + SHi x aH + SLi x aL) x Pi
•
For PAC:
TEi = (SHHi x aHH + SHi x aH + SLi x aL) x Pi
TGi = 0
•
Weighing by wind speed is not carried out for models with their speed set only as High or only as High and low.
•
Distribution ratios are not calculated when you have chosen not to perform distribution ratio calculations. (See “6.3.2
Setting the date, cut-off date, and distribution ratio calculation method”)
