Abstract

A refrigerator appliance (and associated method) that includes a condenser, evaporator and a multi-capacity compressor. The appliance also includes a pressure reducing device arranged within an evaporator-condenser refrigerant circuit, and a valve system for directing or restricting refrigerant flow through the device. The appliance further includes a controller for operating the compressor upon the initiation of a compressor ON-cycle at a priming capacity above a nominal capacity for a predetermined or calculated duration.

Variable gas spring for matching power output from FPSE to load of refrigerant compressor

Patent Chen, Gong [Athens, OH]; Beale, William T [Athens, OH]

The power output of a free piston Stirling engine is matched to a gas compressor which it drives and its stroke amplitude is made relatively constant as a function of power by connecting a gas spring to the drive linkage from the engine to the compressor. The gas spring is connected to the compressor through a passageway in which a valve is interposed. The valve is linked to the drive linkage so it is opened when the stroke amplitude exceeds a selected limit. This allows compressed gas to enter the spring, increase its spring constant, thus opposing stroke increase andmore » « less

Dual capacity compressor with reversible motor and controls arrangement therefor

Patent Sisk, Francis J [Washington Township, Fayette County, PA]

A hermetic reciprocating compressor such as may be used in heat pump applications is provided for dual capacity operation by providing the crankpin of the crankshaft with an eccentric ring rotatably mounted thereon, and with the end of the connecting rod opposite the piston encompassing the outer circumference of the eccentric ring, with means limiting the rotation of the eccentric ring upon the crankpin between one end point and an opposite angularly displaced end point to provide different values of eccentricity depending upon which end point the eccentric ring is rotated to upon the crankpin, and a reversible motor inmore » « less

Dilution cycle control for an absorption refrigeration system

Patent Reimann, Robert C [Lafayette, NY]

A dilution cycle control system for an absorption refrigeration system is disclosed. The control system includes a time delay relay for sensing shutdown of the absorption refrigeration system and for generating a control signal only after expiration of a preselected time period measured from the sensed shutdown of the absorption refrigeration system, during which the absorption refrigeration system is not restarted. A dilution cycle for the absorption refrigeration system is initiated in response to generation of a control signal by the time delay relay. This control system is particularly suitable for use with an absorption refrigeration system which is frequentlymore » « less

Electrochemical compressor refrigeration appartus with integral leak detection system

Patent Bahar, Bamdad

An electrochemical compressor system, such as an electrochemical refrigeration system includes a sealed vessel that reduces leak issues related to the electrochemical cell. The sealed vessel may be molded or formed from a polymer or a composite polymer having reinforcing materials, such as fibers therein. The sealed vessel may be plated with metal to reduce gas permeation through the wall of the vessel and to accommodate and improve the attachment of conduits, including metal conduits thereto. A metal conduit may be brazed onto a vessel and the brazing material may be selected for polymer to metal joining and for reducedmore » « less

Fault detection and diagnosis for refrigerator from compressor sensor

Patent Keres, Stephen L.; Gomes, Alberto Regio; Litch, Andrew D.

A refrigerator, a sealed refrigerant system, and method are provided where the refrigerator includes at least a refrigerated compartment and a sealed refrigerant system including an evaporator, a compressor, a condenser, a controller, an evaporator fan, and a condenser fan. The method includes monitoring a frequency of the compressor, and identifying a fault condition in the at least one component of the refrigerant sealed system in response to the compressor frequency. The method may further comprise calculating a compressor frequency rate based upon the rate of change of the compressor frequency, wherein a fault in the condenser fan is identifiedmore » « less
