Summary of Predictor-Corrector Procedure[LINK]
The predictor-corrector scheme can be summarized as follows:
Using Equation [eq:SteadyStateSystemOutput], an estimate is made of the air system energy required to balance the equation with the zone air temperature equal to the setpoint temperature.
With that quantity as a demand, the air system is simulated to determine its actual supply capability at the time of the simulation. This will include a plant simulation if necessary.
The actual air system capability is used in Equation [eq:ZoneTemperatureUpdateEquation] to calculate the resulting zone temperature.
