Calculation
Super heat SH = f (E3, E1)
Sub cool SC = f (HPS, E1)
Operational performance rate D = f (SH, SC)
Fans speed conversion value FI = f (WS)
Calculation
Electricity
PIA = f (PS, T2, PINp, PINg)
PIA’ = f (PIA, TS, PS, W, H, R, B)
Gas PGA = f (GIN, TG, PG)
Calculation
Electricity distribution rate RPI = f (PIA’)
Gas distribution ratio RGI = f (PGA)

Calculation
Elements related to ice thermal
storage
ICE = f (TCnight, RPI)
Pice = f (Pc, @e)
Calculation
Amount of electricity used PI = f (RPI, Pc, @e, ICE, Pice)
Amount of gas used GI = f (RGI, Gc, @g)

Calculations for load distribution
Load distribution is calculated according to the following ow.
Note
y “f” indicates a function calculation.
For example, “Operational performance rate D=f (SH, SC)” means that the operational performance rate is calculated using “Super heat SH”
and “Sub cool SC”.
