A HVAC air treatment (HAT) system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates an air flow sensor (AFS), timer control unit (TCU), ultraviolet lamp(s) (UVL), lamp feedback indicator (LFI), liquid distribution atomizer (LDA), leak exhaust fan (LEF), and digital control processor (DCP) is disclosed. The AFS indicates detection of air flow within the HVAC ducts (HVD) to the DCP and may wirelessly communicate with the DCP. The DCP interrogates the TCU to determine when HAT is to occur if HVD air flow is detected and activates the UVL to disinfect air within the HVD. The LFI provides feedback to the DCP to verify that the UVL is operational. The UVL may be positioned at the fresh air intake (FAI), air intake plenum (AIP), evaporator/heat exchanger (HEX), and/or air exhaust plenum (AEP) and may incorporate an adjustable magnetic frame (AMF) allowing UVL retrofit installation.

Air disinfectant system and method

A failsafe hydrocarbon-based gas (HBG) leak detection (HLD) and mitigation (HLM) system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates a hydrocarbon gas sensor (HGS), sensor signal conditioner (SSC), alarm status indicator (ASI), and digital control processor (DCP) is disclosed. The HGS detects ambient hydrocarbon gas (AHG) and presents a hydrocarbon sensor voltage (HSV) to the SSC. The DCP and SSC form a closed control loop (CCL) in which the SSC electrical characteristics are adjusted by the DCP such that the HSV is continuously and dynamically recalibrated to account for background HBG levels, changes in ambient air conditions, HGS manufacturing tolerances, and other field-specific operational conditions that impact the HGS detection capabilities. The DCP is configured to log alarms to the ASI if a HGS HBG leak is detected and optionally shutdown gas flow to one or more HBG target (HBT) system components.

Failsafe gas leak detection and mitigation system and method

A refrigerant leak detection and mitigation system/method for use in heating, ventilation, and air conditioning (HVAC) systems that incorporates a refrigerant gas sensor (RGS), sensor signal conditioner (SSC), alarm status indicator (ASI), and digital control processor (DCP) is disclosed. The RGS detects ambient refrigerant gas (ARG) and indicates this as a refrigerant sensor voltage (RSV) to the SSC. The DCP and SSC form a closed control loop (CCL) in which the SSC electrical characteristics are adjusted by the DCP such that the RSV is continuously and dynamically recalibrated to account for background refrigerant gas levels, changes in ambient air conditions, RGS manufacturing tolerances, and other field-specific operational conditions that impact the RGS detection capabilities. The DCP is configured to log alarms to the ASI if a RGS refrigerant leak is detected and optionally shutdown one or more HVAC system components such as a specific air handler leaking refrigerant.
