modelWaterDesignTemperature
Information
Hypothesis and equations
On/Off control model for a heat generator, according to the hydraulic circuit temperature.
The number of points of the water design curve has to be chosen based on the need (system output water temperature depending on exterior temperature, 3 temperature points minimum).
