Information
Hypothesis and equations
Simple model of heating and air conditioning with constant temperature setpoints.
The output Besoin is positive when heating is needed, and negative when cooling is needed.
Bibliography
none
Instructions for use
none
Known limits / Use precautions
Of course, this model should not be used if Tc < Tf.
Safeguards should be added to prevent bug.
