Benefits of technology

[0008]According to one aspect of the present disclosure, an energy saving defrost control system for reducing power consumption of an electromechanically controlled refrigerator is provided. The system includes a defrost timer adapted to control a compressor according to an established run time, a defrost heater control operatively connected to the defrost timer and con

Problems solved by technology

Many utilities are currently experiencing a shortage of electric generating capacity due to increasing consumer demand for electricity.
Although these systems are capable of being run automatically according to demand period, a user may choose to override the system and run a device normally, or delay the operation of the system for a particular period of time.
However, such a DSM/SAM add-

Embodiment Construction

[0021]An exemplary embodiment of an energy management system for household appliances 100 is illustrated in FIG. 1. An electronic controller 102 is provided for communicating with a utility meter and reducing power consumption in response to a signal 106 indicative of a peak demand period. Electromechanically controlled refrigerators, according to one aspect of the present disclosure, include a cold control 120 to control the temperature of the refrigerator compartments, which is depicted in FIG. 2. A cold control 120 is a temperature control incorporating a single pole, single throw switch with an associated set of electrical contacts for turning a refrigerator's compressor and fans concurrently on and off. A bourdon tube 122 is associated with the cold control 120 to sense temperature increases and decreases in a refrigerator compartment. As introduced above, a bourdon tube 122 is a hollow tube filled with refrigerant or an inert gas and placed in the airstream of the compartment ...

Abstract

An energy saving defrost control system for reducing power consumption of an electromechanically controlled refrigerator is provided. The system includes a defrost timer adapted to control a compressor according to an established run time, a defrost heater control operatively connected to the defrost timer and configured to activate a defrost heater in response to a timeout by the defrost timer, a DSM module responsive to demand state signals from an associated utility indicative of at least a peak demand and off peak demand state, and a time delay latching relay having a timer and configured to switch to one of a low position and a high position based on the demand state signal.

Description

BACKGROUND OF THE DISCLOSURE[0001]This disclosure relates to energy management, and more particularly to energy management of household refrigeration appliances. The disclosure finds particular application to adapting electromechanically controlled refrigerators for operation in home energy management systems.[0002]Many utilities are currently experiencing a shortage of electric generating capacity due to increasing consumer demand for electricity. Currently utilities charge a flat rate, but with increasing cost of fuel prices and high energy usage at certain parts of the day, utilities have to buy more energy to supply customers during peak demand, which causes prices to rise during these times. If peak demand can be lowered, then a potential huge cost savings can be achieved and the peak load that the utility has to accommodate is lessened. In order to reduce high peak power demand, many utilities have instituted time of use (TOU) metering and rates which include higher rates for ...
