Window air conditioner demand supply management response

摘要

An appliance for conditioning air of an associated room and an associated method for controlling an air conditioner are disclosed, the controller selectively adjusting operation of the air conditioning appliance based on historical operating data. The controller adjusts a set-point of the appliance for a preselected period of time in response to the historical operating data of the appliance when the appliance operates in an energy savings mode. The controller is configured to receive and process data relating to the rate of change in the temperature. Further, an override feature may be included to maintain operation of the appliance in a normal operation mode if ambient temperature reaches a predetermined threshold value. Another feature is that the controller determines whether the compressor has been operational less than a preselected period of time and, if so, the compressor is operated until such time period has elapsed.

主权项

1. An appliance for conditioning air of an associated room, the appliance configured to receive and process data relating to a rate of change in temperature of the associated room, and the appliance is in receipt of a demand response signal representative of operation in an increased cost or demand for energy period, wherein the appliance has been operating for 100% of the time over a predetermined time period prior to processing the demand response signal, and wherein a temperature of the associated room is not nearing stabilization to a temperature set point that a user selected, the appliance comprising:
a refrigeration system comprising one or more power consuming elements for one of heating and cooling air; a sensory device configured to measure temperature of the associated room; and a controller operatively connected to the refrigeration system, the controller being configured to:
receive and process the demand response signal,determine that the appliance has been operating for 100% of the time over the predetermined time period,receive and process the data relating to the rate of change in the temperature of the associated room, andanalyze the data indicating the rate of change in temperature to determine that the temperature of the associated room is not nearing stabilization, and, in response to the determination that the temperature of the associated room is not nearing stabilization, the controller executing a percentage load reduction program based on historical operating data of the appliance,wherein the percentage load reduction program is executed to reduce the load or percent run time of at least one of the one or more power consuming elements of the refrigeration system.
