  • Systems and methods for predicting refrigerant leakage of a critically charged HVAC/Refrigeration system
    Patent number: 12359830
    Abstract: A system for predicting a leak of a HVAC/Refrigeration system includes a critically charged HVAC/Refrigeration system configured to circulate a refrigerant to cool a space, and processing circuitry. The processing circuitry is configured to obtain the subcooling data from the critically charged HVAC/Refrigeration system. The processing circuitry is configured to predict a leak event by providing the subcooling data as an input to a neural network. The neural network is trained using historical data of one or more subcooling parameters of a plurality of critically charged HVAC/Refrigeration systems. The processing circuitry is configured to operate a display to provide a notification to a technician or a manager regarding the predicted leak event at the critically charged HVAC/Refrigeration system.
