TGi is the gas consumption index for indoor unit No. i. TOi is the fuel consumptionindex for indoor unit No. i.z When the object of electricity distribution calculations is “thermostat ON time” and “thermostat OFF time” (regular timedistribution)The electricity consumption index is calculated with “cumulative operating time” and “thermostat ON cumulative time”.The gas consumption index and fuel consumption index are calculated with “thermostat ON cumulative time”.y GHPElectricity TEi = (RHHi×αHH+RHi×αH+RLi×αL)×PiGas TGi = (SHHi×αHH+SHi×αH+SLi×αL)×Piy PACElectricity TEi = {(RHHi×αHH+RHi×αH+RLi×αL)÷k+(SHHi×αHH+SHi×αH+SLi×αL)}×PiGas TGi = 0z When the object of electricity distribution calculations is “thermostat ON time” (thermostat ON time distribution)The electricity consumption index, gas consumption index and fuel consumption index are calculated with “thermostat ON cumulative time”.y GHPElectricity TEi = (SHHi×αHH+SHi×αH+SLi×αL)×PiGas TGi = (SHHi×αHH+SHi×αH+SLi×αL)×Piy PACElectricity TEi = (SHHi×αHH+SHi×αH+SLi×αL)×PiGas TGi = 0Methodology for calculating electricity/gas consumption index across the whole distributiongroupThe electricity/gas consumption index for the distribution group as a whole is the total electricity/gas consumption index for all indoor unitsincluded in the relevant distribution group.TOTALe is the electricity consumption index for the distribution group as a whole. TOTALg is the gas consumption index for the distributiongroup as a whole. m is the number of indoor units included in the relevant group.Electricity consumption index TOTALe = TE1 + TE2 + … + TEmGas consumption index TOTALg = TG1 + TG2 + … + TGmMethodology for calculating electricity/gas consumption distribution for indoor unit No. iREi is the electricity consumption distribution ratio. RGi is the gas consumption distribution ratio.Distribution ratio of electricityconsumedREi (%) = TEi / TOTALe ×100Distribution ratio of gas consumed RGi (%) = TGi / TOTALg ×100Methodology for calculating electricity/gas consumption distribution for area jThe electricity/gas consumption distribution ratio for the area as a whole is the total of electricity/gas consumption distribution ratio for all indoorunits included in the relevant area.NEj is the electricity consumption distribution ratio in Area j. NGi is the gas consumption distribution ratio in Area j. n is the number of indoorunits included in the relevant area.Distribution ratio of electricityconsumedNEj = RE1 + RE2 + … + REnDistribution ratio of gas consumed NGj = RG1 + RG2 + … + RGnNotey For models whose only setting for fan speed is “High”, or for models whose only settings are “High” or “Low”, you cannot give weighting foreach speed.y Distribution ratios are rounded to two decimal places for display.Methodology for calculating distributions193Appendix AppendixCalculating the air conditioning usage volumeYou can calculate either the electricity/gas consumed by a distribution group as a whole or for individual indoor units.Methodology for calculating electricity/gas usage across the whole distribution groupThe formula for calculating the electricity usage or gas usage for a distribution group is as follows.Quantity of electricity used Pulse meter (electricity meter) count value x pulse unit quantity (kWh)Quantity of gas used Pulse meter (gas flow meter) count value x pulse unit quantity (m3 )Methodology for calculating electricity/gas consumption usage for each indoor unitThe formula for calculating the electricity usage or gas usage for an individual indoor unit is as follows.Quantity of electricity used Electricity usage of the distribution group x the distribution ratio of electricity consumed by indoor unitsQuantity of gas used Gas usage of the distribution group x the distribution ratio of gas consumed by indoor unitsFor the methodology for calculating the distribution ratio of electricity/gas consumed by indoor units, refer to “Methodology for calculatingelectricity/gas consumption distribution for indoor unit No. i ” (P.192).Notey Usages are rounded to two decimal places for display.Methodology for calculating distributions
