Use
The volume flow controller regulates the volume flow of cooling systems depending on the current system temperature.
Parameters and Connectors
The reference volume flow is controlled by a current measured temperature (▶TAct) and a reference temperature (▶TRef). If the measured temperature (e.g. storage temperature) exceeds the reference temperature by deltaTup the volume flow output is set to qvMax. If the measured temperature falls below the reference temperature by deltaTlow the volume flow output is set to 0. A linear interpolation is performed between these extreme values.
Model Background
The following figure shows how the output volume flow behaves as a function of the temperature difference between ▶TAct and ▶TRef. In this case, deltaTup = 1, deltaTlow = -1 and qvMax = 3 m³/s are assumed.
