Information

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.
