Abstract
A method includes providing a standard supply of electrical power to a defrost heater during a standard defrost cycle for a refrigeration system of an appliance, detecting a high energy demand period during the standard defrost cycle, and enabling a reduced consumption of electrical power by the defrost heater in a low power defrost cycle.
Claims20
A method comprising:
- providing a standard supply of electrical power to a defrost heater during a standard defrost cycle for a refrigeration system of an appliance;
- detecting a high energy demand period during the standard defrost cycle;
- and
- enabling a reduced consumption of electrical power by the defrost heater in a low power defrost cycle.
1 more element
A control system for a defrost heater in a refrigeration system, comprising:
- a power supply connection;
- a controller configured to determine a demand side management state signal;
- and
- a power switching unit coupled between the power supply connection and the defrost heater, the power switching unit being configured to switch a power consumption state of the defrost heater in a defrost cycle from a standard power consumption mode to a reduced power consumption mode when the demand side management state signal is detected during the standard consumption mode.
1 more element
A refrigerator comprising:
- a compartment;
- an evaporator in heat transfer association with the compartment;
- a defrost heater associated with the evaporator;
- and
- a controller configured to switch an energy consumption state of the defrost heater from a standard energy consumption state to a reduced energy consumption state when a peak power demand state is detected.
