ABSTRACT:
A refrigerant monitoring system for a heating or cooling system includes a neural network that is used to compute the refrigerant charge in at least one refrigeration circuit of the system. The neural network is trained to learn certain characteristics of the heating or cooling system during a development mode of operation. The thus trained neural network timely computes refrigerant charge during a run time mode of operation. Information as to the computed refrigerant charge being at variance with the nominal amount of refrigerant charge for at least one refrigeration circuit is made available for assessment during the run time mode of operation.
