Abstract
An apparatus and method for operating an appliance in an energy conservation mode is described. The appliance includes a number of peripheral devices and auxiliary components ancillary to main operation of the appliance, and the method includes reducing power to at least some of the peripheral devices and auxiliary components in an energy conservation mode, thereby reducing energy consumption by the peripheral devices and auxiliary components.
Claims18
A method for operating an appliance in an energy conservation mode, the appliance comprising a number of peripheral devices and auxiliary components ancillary to main operation of the appliance, said method comprising:
- reducing power to at least some of the peripheral devices and auxiliary components in an energy conservation mode corresponding to an appliance set point, thereby reducing energy consumption by the peripheral devices and auxiliary components;
- wherein the appliance is a refrigerator, the peripheral devices including a quick chill compartment, said reducing power to at least some of the peripheral devices comprising disabling at least the quick chill compartment.
A method for operating an appliance in an energy conservation mode, the appliance comprising a number of peripheral devices and auxiliary components ancillary to main operation of the appliance, said method comprising:
- reducing power to at least some of the peripheral devices and auxiliary components in an energy conservation mode corresponding to an appliance set point, thereby reducing energy consumption by the peripheral devices and auxiliary components;
- wherein the appliance is a refrigerator, the auxiliary components including at least one auxiliary fan, said reducing power to at least some of the auxiliary components comprising disabling at least the auxiliary fan.
A method for operating an appliance in an energy conservation mode, the appliance comprising a number of peripheral devices and auxiliary components ancillary to main operation of the appliance, said method comprising:
- reducing power to at least some of the peripheral devices and auxiliary components in an energy conservation mode corresponding to an appliance set point, thereby reducing energy consumption by the peripheral devices and auxiliary components;
- wherein the appliance is a refrigerator, the peripheral devices including a dispenser including a heater, said reducing power to at least some of the peripheral devices comprising disabling at least the heater.
A method for operating an appliance in an energy conservation mode, the appliance comprising a number of peripheral devices and auxiliary components ancillary to main operation of the appliance, said method comprising:
- reducing power to at least some of the peripheral devices and auxiliary components in an energy conservation mode corresponding to an appliance set point, thereby reducing energy consumption by the peripheral devices and auxiliary components;
- wherein the appliance is a refrigerator, the peripheral devices including a dispenser including a heater, said reducing power to the peripheral devices comprising reducing a duty cycle of the heater.
A method for operating a refrigerator in an energy conservation mode, the refrigerator including at least one refrigeration compartment and a sealed system for forcing cold air therethrough, the refrigerator further including a number of peripheral devices and auxiliary components;
- said method comprising:
- operating the sealed system at normal temperature settings in a normal mode of operation;
- and
- disabling at least one of the peripheral devices and auxiliary components at a predetermined temperature setting corresponding to an energy conservation mode, thereby preventing the disabled peripheral device and auxiliary component from consuming energy.
A method for controlling a refrigerator, the refrigerator including at least one refrigeration compartment and a sealed system for forcing cold air therethrough, the refrigerator further including a number of peripheral devices and auxiliary components, the refrigerator operable at a number of temperature settings through a controller, said method comprising:
- accepting a target temperature set point for the at least one refrigeration compartment;
- operating the sealed system in normal operation according to the accepted setting;
- when a designated low energy mode setting is accepted, suspending operation of at least one of the peripheral devices and auxiliary components, thereby preventing the disabled peripheral device and auxiliary component from consuming energy;
- and
- operating the peripheral devices and auxiliary components on demand when the accepted setting is other than the designated setting.
A controller for a refrigerator including at least one refrigeration compartment, a sealed system for cooling the at least one compartment, and a number of peripheral devices and auxiliary components ancillary to cooling functions of the refrigerator, said controller configured to be operatively coupled the sealed system and to each of the peripheral devices and auxiliary components, said controller configured to:
- operate said sealed system, peripheral devices, and auxiliary components in a normal mode of operation according to user preferences and;
- adjust operation of said peripheral devices and auxiliary components when a low energy mode is activated through selection of a predetermined sealed system set point, thereby reducing energy consumption by the peripheral devices and auxiliary devices.
A refrigerator comprising:
- a cabinet;
- at least one refrigeration compartment within said cabinet;
- a sealed system in flow communication with said cabinet;
- a controller coupled to the sealed system for controlling an operating temperature of said at least one refrigeration compartment;
- and
- at least one device coupled to said controller and ancillary to operation of said sealed system, said controller configured to control said sealed system and said device in a normal mode corresponding to a normal temperature set point, and to operate said device in a low energy mode corresponding to a low energy mode temperature set point to reduce energy consumption by said device.
