.TransiEnt.Producer.Heat.SolarThermal.Control.ControllerPumpSolarCollectorDeltaT

Information

1. Purpose of model

Controller model to control the pump for a solar thermal collector by the temperature difference of inlet and outlet temperatures.

2. Level of detail, physical effects considered, and physical insight

A hysteresis with the temperature difference models real controller behavior. The onOffRelais avoids having too many switching events. The first order block smoothens the output.

3. Limits of validity

(Purely technical component without physical modeling.)

4. Interfaces
