This block implements an ideal control of the evaporator (or condenser) water
mass flow rate.
The control intent aims to maintain a constant water temperature difference
dT_nominal across the heat exchanger, within the limit of a
minimum mass flow rate ratio ratFloMin.
For computational performance and to avoid the use of a PI controller,
the required mass flow rate is computed based on a signal representative of
the load.
