Classification: CPC F | IPC F

Claim 15:
16. A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
a first vibration sensor coupled to a first component of the HVAC system;
a second vibration sensor coupled to a second component of the HVAC system; and
a data analyzer with a processor configured to:
receive a first input from the first vibration sensor coupled to the first component of the HVAC system;
determine a first remaining useful life (RUL) indication for the first component of the HVAC system based on applying a first analytical model using the first input from the first vibration sensor;
receive a second input from the second vibration sensor coupled to the second component of the HVAC system;
determine a second RUL indication for the second component of the HVAC system based on applying a second analytical model using the second input from the second vibration sensor;
determine fault mechanism interactions between the first component and the second component based on data indicative of the first component and of the second component; and
determine an overall RUL indication for the HVAC system based on the first RUL indication, the second RUL indication, and the fault mechanism interactions between the first component and the second component.
