Abstract
A refrigerant leak detection (RLD) and/or mitigation/containment (RLM/RLC) system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates a plurality of temperature and/or humidity sensors (THS), alarm status indicator (ASI), and digital control processor (DCP) is disclosed. The THS are positioned within the HVAC system (condenser coils (HCC), evaporator coils (HEC), air intake fans (AIF), air supply plenums (ASP), air return plenums (ARP), and/or temperature controlled environment (TCE)) and reports THS temperature readings to the DCP via a common temperature sensor bus (TSB) and/or a wireless temperature interface (WTI). The DCP interprets THS temperature readings in a closed control loop (CCL) to dynamically determine if a refrigerant leak has occurred within the HVAC system. If a leak is detected, the DCP activates the ASI and optionally one or more refrigerant control valves (RCV) is closed to limit refrigerant leakage in the HVAC system.
