    摘要: A refrigerant cycle is provided with a transient mode for moving from a defrost cycle back to steady state operation. In particular, some default position of the expansion device is selected when defrost cycle ends. The evaporator is hot at the end of defrost cycle, and might otherwise suggest an increased flow of refrigerant through the expansion device, which could be undesirable. Thus, a control for the inventive system moves the expansion device to a defrost transient position, with the defrost transient position restricting the flow of refrigerant to a value that would be less than that dictated by the high temperature of the evaporator. At some period of time after the end of the defrost mode, the refrigerant cycle can be returned to state steady operation.

    摘要: A method of heating a dispenser door by applying direct heat to only a peripheral region of a front layer of the door at a rate sufficient to heat an edge surface of the door to a point above zero degrees Centigrade. In one embodiment this is done by placing a perimeter heater in a flange attached to the rear end of a tubular wall extending from the periphery of a central region of the front layer of the door.

    摘要: A freezer includes a refrigeration surface that can be frozen, such as an evaporator surface, a heating device for heating the refrigeration surface, and a control circuit for controlling the operation of the heating device in accordance with a timer. The control circuit is configured to block the operation of the heating device for a time period that is defined by the timer. The timer is used to ensure that the refrigeration surface is only heated to defrost the freezer, if the refrigeration power requirement of the latter is low.

    摘要: A damper apparatus for controlling airflow between compartments in a two compartment refrigerator having a door includes a controller for controlling opening and closing of a damper; and a door sensor connected to the controller for detecting when the door is open. If the controller determines that the door has remained closed for a set period, the controller maintains the damper in the closed position. A method for cleaning a damper in a refrigerator includes a steps of defrosting a refrigeration apparatus of the refrigerator, at least partially opening the damper, followed by waiting for a set period and then at least partially closing the damper. The steps of at least partially opening and waiting are repeated a set number of times and then a cooling operation of the refrigeration apparatus is commenced.

    摘要: An integrated refrigeration control (IRC) module is disclosed which combines both thermal and electrical protection to the main components of a refrigerator and uses sensor inputs to control the compressor. The IRC module employs triacs (Q2, Q4, Q6, Q8, Q10) to control power to the start and run windings of the compressor motor, evaporator and compressor fans and the defrost heater. The module adaptively controls the refrigerator defrost cycle using pervious defrost cycle run times to determine new cumulative compressor run times. Also disclosed is the use of preventive defrost periods performed for brief periods at intervals between portions of the cumulative compressor run time.
