Filed:

Sep 30, 2005

Appl. No.:

11/241652

Inventors:

Kenneth Green - Denton TX, US
Kevin Klughart - Denton TX, US

International Classification:

G05D 23/00

US Classification:

700276000

Abstract:

A HVAC diagnostic system and method is disclosed which permits bypassing the normal operation of a thermostat by HVAC service personnel, typically permitting the HVAC service personnel control over thermostat functionality while servicing the condenser coils and/or compressor located external to customer building. The present invention is useful in situations where HVAC service calls must be scheduled at customer premises such as homes, apartments, etc., during normal hours where the occupants are not typically available to permit access to the thermostat within the building structure. By permitting override of the customer thermostat at the compressor/condenser unit, the system permits servicing of this unit without customer assistance. As such, HVAC service can be completed on a more regular schedule, saving substantial energy and providing improved customer environmental comfort.

International Classification:

F25B 41/31
F25B 41/20
F25B 41/40

Abstract:

A refrigerant metering system/method incorporating a manual expansion valve (MEV), condenser isolation valve (CIV), flow isolation valve (FIV), and evaporator isolation valve (EIV) is disclosed. The MEV is configured to replace a conventional automated expansion valve (AEV) that controls a refrigerant flow valve (RFV) that is positioned in a heating, ventilation, and air conditioning (HVAC) system between a refrigerant condenser coil (RCC) and a refrigerant evaporator coil (REC) and permits manual metering of refrigerant by the RFV from the RCC to the REC and also allows complete shutoff of refrigerant flow by the RFV from the RCC to the REC. The MEV allows rapid HVAC repair and restoration of service where a replacement AEV is not readily available. The CIV/FIV/EIV are positioned in the refrigerant flow lines to permit the AEV and/or REC to be isolated from HVAC refrigerant flow for repairs to the AEV and/or REC.

International Classification:

Abstract:

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.

Abstract:

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.

Abstract:

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.
