This model is to validate the block IDEAS.Controls.OBC.Utilities.OptimalStart for space cooling system with a negative simulation start time.
The room is modeled as a simple differential equation with a
time constant of around 5.6 hours. The cooling power is relatively
large compared to the heat gain from the outdoor temperature. The
outdoor temperature is repetitive each day; the optimal start time
converges to a small amount of time tOpt after a few
days.
