Calculation
PIA = f (PS, T2, PINp, PINg)
Electricity
PIA' = f (PIA, TS, PS, W, H, R, B)
Gas PGA = f (GIN, TG, PG)
Calculation
Electricity distribution rate
Gas distribution ratio
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".

SH = f (E3, E1)
SC = f (HPS, E1)
D = f (SH, SC)
FI = f (WS)
PINp = f (D, FI, PS)
PINg = f (0)
GIN = f (D, FI, PS)
