Classification: CPC F | IPC F

Claim 7:
8. A non-transitory computer readable storage medium for a heating, ventilation, and/or air conditioning (HVAC) system comprising instructions that, when executed by a processor, cause the processor to:
receive an input from a vibration sensor coupled to a component of the HVAC system;
receive an indication of a parameter associated with the HVAC system;
select, based on the indication of the parameter, an analytical model from a library of analytical models stored in a memory, wherein each analytical model of the library of analytical models is configured to calculate a remaining useful life (RUL) of the component;
determine and output an RUL indication for the component of the HVAC system based on applying the analytical model using the input from the vibration sensor;
determine fault mechanism interactions between the component and an additional component of the HVAC system based on data indicative of the component and of the additional component; and
determine an overall RUL indication for the HVAC system based on the RUL indication for the component and the fault mechanism interactions between the component and the additional component.
