Abstract: A refrigerant leak management system for a heating, ventilating, and air conditioning (HVAC) system is disclosed. The system includes a controller communicatively coupled to one or more sensors disposed within the HVAC system. The controller measures a vibration pattern associated with a component of the HVAC system. The controller determines whether the vibration pattern is indicative of a refrigerant leak in the HVAC system. Additionally, the controller can modify operation of the HVAC system when the vibration pattern is indicative of the refrigerant leak in the HVAC system.

Abstract: A leak detection system for heating, ventilating, and air conditioning (HVAC) equipment includes a refrigerant circuit, where the refrigerant circuit includes tubing configured to couple components in the refrigerant circuit and where the tubing is configured to enclose a refrigerant flowing throughout the refrigerant circuit. The leak detection system further includes a processor coupled to the tubing of the refrigerant circuit, where the processor is configured to detect a variation in physical geometry of the tubing by comparing the measured electrical property to a baseline measurement.
