摘要:
A refrigeration appliance with a hot water dispenser includes a refrigerated cabinet having a dispenser area, a cabinet water inlet in the refrigerated cabinet connectable to a premises water line, and a hot water storage tank. The tank has a tank body, a heater in the tank body, an inlet for admitting water into the tank body supplied via the cabinet water inlet, and an outlet for providing water via a dispensing conduit to a dispenser in the dispenser area. The inlet includes a venturi portion for creating a reduced pressure within the hot water storage tank via flow of water into the hot water storage tank. The reduced pressure communicates with the dispensing conduit via the outlet so that, after dispensing water remaining in the dispensing conduit is drawn toward the tank body. Refrigeration devices with premises line pressure water distribution systems are also disclosed.

An assembly for filtering water includes a housing, a water inlet for supplying unfiltered water to the housing, and a water filter including an outer casing attached to the housing in communication with the water inlet and a filter medium within the outer casing, the water filter filtering the unfiltered water through filter medium to provide filtered water. A water outlet is attached to the housing for transferring filtered water from the outer casing to a device via the housing. Some sort of indicia is located on the outer casing, and an optical device detects a feature of the indicia to determine if the water filter is properly installed in the housing. Related refrigeration appliances incorporating such devices are also disclosed.

摘要:
A refrigerator and a method of operating a refrigerator to determine the time at which to initiate a defrost cycle is provided. Changes in the voltage provided to an evaporator fan are used to determine and/or predict when to initiate a defrost cycle. Adjustments to the timing of the defrost cycle can be made based on known periods of peak energy demand and/or the increased costs associated with operating the defrost cycle during such peak energy demand periods.

摘要:
Apparatus and methodologies are provided to improve the refrigeration system by precisely controlling refrigerator compartment and heat exchanger temperatures through continuous modulation of device speeds or positions to match capacity with instantaneous load. A controller in a refrigerator is configured to provide a plurality of control loops to control various operational aspects of selected components in the refrigerator. A first loop controls the operating speed of a compressor based on temperature of the evaporator or based on the desired speed of an evaporator fan. A second control loop controls speed of an evaporator fan to maintain a prescribed freezer compartment temperature. A third control loop maintains a prescribed temperature in a fresh food compartment. In certain embodiments selected of the control loops may be thermodynamically coupled by way of thermal interaction between the various cooled compartments rather than being electrically coupled. The control loops may be individually configured as one of a proportional, proportional-integral, or proportional-integral-derivative control loop.
摘要:
A consumer refrigeration appliance, such as a refrigerator, includes a refrigeration system charged with a refrigerant and further having a compressor, a condenser, an expansion device, and an evaporator. At least one of the evaporator or condenser is a spine fin heat exchanger having a defined length of tube with a spine fine material configured around at least a portion of tube. The tube has a reduced refrigerant side diameter that provides a reduced refrigerant side area defined by the tube length and refrigerant side diameter. The refrigeration system has a reduced refrigerant charge mass.

摘要:
Apparatus and methodologies are provided to monitor temperature from at least two locations on an evaporator in a refrigeration system. Operational characteristics of one or more of the compressor, condenser and evaporator cooling fans are adjusted based on the difference in temperature between the two locations on the evaporator. In some systems a second evaporator may be provided along with a refrigerant control valve. Cooling air flow across the second evaporator and refrigerant distribution between the plural evaporators may also be control.
