ABSTRACT:
A method for detecting and predicting refrigerant level includes the steps of determining an estimated value for a parameter indicative of refrigerant level and comparing that estimated value to an actual value. The difference between the actual and estimated value provides a refrigerant charge indicator value. The charge indicator value is indicative of the amount of refrigerant contained within the system. A change value is combined with the charge indicator value to provide a prediction for the future value of the charge indicator value. This future value is determined based on a rate of change and charge indicator value over a selected period of time.
