10 CALCULATING AIR CONDITIONER DISTRIBUTION
Calculate electricity/gas usage index of entire distribution group
Let "TOTALe" be the electricity usage index of entire distribution group,
and let "TOTALg" be the gas usage index of entire distribution group.
Let "m" be the number of indoor units in the distribution group.
TOTALe = TE1 + TE2 + ··· + TEm
TOTALg = TG1 + TG2 + ··· + TGm
Calculate electricity/gas usage distribution ratio of indoor units
Let "REi" be the electricity usage distribution ratio,
and let "RGi" be the gas usage distribution ratio.
REi (%) = TEi / TOTALe × 100
RGi (%) = TGi / TOTALg × 100
Calculate electricity/gas usage distribution ratio of tenant j
Let "NEj" be the electricity usage distribution ratio of tenant j,
and let "NGj" be the gas usage distribution ratio of tenant j.
Let "n" be the number of indoor units of tenant j.
NEj (%) = RE1 + RE2 + ··· + REn
NGj (%) = RG1 + RG2 + ··· + RGn
Distribution ratios are rounded at the third decimal place and shown to the second decimal
place.
* The following table shows which of the formulas
distribution modes.
See "About distribution ratios in 12 Supplementary Information-2".
