Abstract: A method to control a fixed-sequence dual evaporator cooling system including providing a recurring cooling cycle cooling system wherein each recurring cooling cycle comprises first and second cooling cycles for cooling respective first and second interiors, a pump-out cycle for returning coolant to a condenser, and an idle cycle, and providing a processor to establish exceptions to the recurring cooling cycle. A step includes the processor monitoring first and second actual temperatures of the respective first and second interiors, selecting predetermined first and second control temperatures for the respective first and second interiors, and selecting a command input signal to supply to a compressor, the condenser fan, the first and second evaporator fans, and the valve of the cooling system during the recurring cooling cycle based upon the first and second actual temperatures and the predetermined first and second control temperatures to initiate the established exceptions.

Abstract: An appliance includes a cabinet; a first compartment; and a second compartment. The first compartment and the second compartment are separated by a horizontal mullion. The cabinet also typically includes a coolant system that has: a single compressor for regulating a temperature of the first compartment and a temperature of the second compartment operably connected to at least one evaporator; a shared coolant fluid connection system; and a coolant fluid spaced within the shared coolant fluid connection system used to regulate both the temperature of the first compartment and the second compartment. The compressor can provide the shared coolant at least two different pressures to at least one evaporator using the shared coolant fluid connection circuit. The ratio of the substantially steady state heat gain for the first compartment to the substantially steady state total heat gain for the overall cabinet is about 0.65:1 or greater.

Abstract: A refrigerator appliance configuration, and associated methods of operation, for an appliance with a controller, a condenser, at least one evaporator, a compressor, and two refrigeration compartments. The configuration may be equipped with a variable-speed or variable-capacity compressor, variable speed evaporator or compartment fans, a damper, and/or a dual-temperature evaporator with a valve system to control flow of refrigerant through one or more pressure reduction devices. The controller, by operation of the compressor, fans, damper and/or valve system, depending on the appliance configuration, synchronizes alternating cycles of cooling each compartment to a temperature approximately equal to the compartment set point temperature.

Abstract: An ice maker assembly includes an ice forming plate and a cooling source thermally engaged to a bottom surface of the ice forming plate. The cooling source is configured to freeze water coming into contact with a top surface of the ice forming plate. A containment wall surrounds the top surface of the ice forming plate to define an ice tray that is configured to retain water. An electrical drive body is rotatably coupled to the ice tray and is configured to oscillate the ice-forming plate in a rocking cycle about a transverse axis of the ice tray. A median wall divides the ice tray along the transverse axis into a first reservoir and a second reservoir. The rocking cycle causes water to repeatedly move over the median wall to form layers of an ice piece within each reservoir of the ice tray.

Abstract: A method of operating a refrigeration appliance, comprising the steps: operating a compressor and a valve system to cause refrigerant to flow through a refrigerant circuit to chill an evaporator during a compressor ON-cycle; operating the valve system to direct the refrigerant through a secondary pressure reducing device in response to the initiation of the compressor ON-cycle for a duration that lasts until a nominal operation condition has been reached; operating the valve system during the compressor ON-cycle to direct the refrigerant through a primary pressure reducing device in response to the nominal operation condition; and transferring thermal energy from the primary pressure reducing device to a suction line heat exchanger.
