Abstract: A method for defrosting an evaporator of a refrigeration sealed system, the system including at least one refrigeration compartment and a controller operatively coupled to a compressor, an evaporator, an evaporator fan and a condenser fan, wherein the method includes initiating a defrost cycle, operating the sealed system to prechill the refrigeration compartment, and selectively operating the evaporator fan and the condenser fan to raise a temperature of the evaporator.

Abstract: An appliance includes a dispenser having a water valve for controlling a flow of water through the dispenser and a flowmeter for measuring the amount of water dispensed through the dispenser, and a controller operatively coupled to the water valve and the flowmeter. The controller is configured to receive an input relating to a target volume of water, adjust the target volume for a volume error correction to obtain an adjusted target volume, wherein the volume error correction is based on a flow rate, open the water valve, determine a total volume dispensed using the flowmeter, and close the water valve when the total volume dispensed equals the adjusted target volume.

Abstract: A refrigerator includes a housing having at least one refrigerator compartment, a door for accessing the at least one refrigerator compartment, and an ice-dispensing assembly. The ice-dispensing assembly includes an insulated housing arranged within the at least one refrigerator compartment, an ice-making device arranged within the insulated housing and configured to produce ice, an ice-storage container arranged within the insulated housing, and a dispenser arranged within the door and communicating with the ice-storage container, wherein the dispenser is configured to transfer ice from the ice-storage container to an external portion of the refrigerator.

Abstract: A water dispenser assembly used for a dispensing system includes an inlet configured to receive water from a water supply, and a flow meter in communication with the inlet. The flow meter is configured to measure an amount of water passing therethrough. A first valve is arranged in communication with the flow meter, and the first valve is configured to enable and restrict water flow to an outlet. A controller is operatively coupled to the flow meter and the first valve. The controller is configured to control the dispensing of water based on the measured amount of water passing through the flow meter and based upon a volume error factor correction.

Abstract: A refrigerator includes a refrigeration compartment having an upper region and a lower region, a first evaporator positioned in the upper region, a second evaporator, positioned in the lower region, and a fan disposed between the first and second evaporators. The fan is configured, such that air flows past first and second evaporators and is discharged into said upper and lower regions when said fan is energized.

Abstract: An apparatus and method for defrosting an evaporator of a refrigeration sealed system is described. The system includes a controller operatively coupled to an evaporator fan, a condenser fan and a defrost heater, and the method includes operating the sealed system until a selected time till defrost interval expires, initiating a defrost cycle when the time till defrost interval expires, and selectively operating the sealed system to raise a temperature of the evaporator while the defrost heater is inactivated.

Abstract: An apparatus and method for controlling a sealed system including a variable speed compressor coupled to a controller is described. The method includes establishing a control grid having at least one axis corresponding to a temperature at a specified location, and the axis is divided into a plurality of operating states of the sealed system. Each of the states correspond to a sensed temperature condition at the specified location, and each of the states includes a designated compressor speed parameter. The compressor speed parameter in some of the states is different from the compressor speed parameter in other of the states.
