Claim 14:
15. A non-transitory computer-readable medium comprising computer-executable instructions that, when executed, are configured to cause a processor to:
receive data from a sensor indicative of a concentration of an ultraviolet (UV) tracer measured to be in a monitored gas volume of an HVAC system;
retrieve a ratio of the UV tracer to a refrigerant from a database;
determine a concentration of leaked refrigerant in the monitored gas volume based on the concentration of the UV tracer measured to be in the monitored gas volume and the ratio of the UV tracer to the refrigerant;
define a corrective action output based on the concentration of the leaked refrigerant determined to be in the monitored gas volume exceeding a threshold; and
output the corrective action output to modify operation of the HVAC system.
