Publication number: 20120042666Abstract: An appliance such as a refrigerator receives a demand response signal indicating a peak demand period and operates the refrigerator in an energy savings mode by disabling an anti-sweat heater. A sensor on an external surface of the refrigerator enables the anti-sweat heater during the peak demand period if moisture is detected by the sensor. A preselected location can be defined where incipient moisture would form such as reducing the amount of insulation in this location. By forming a depression in the location and using an impedance-type sensor, moisture can be easily detected. The sensor signal is sent to the controller which then activates the anti-sweat heater to remove the moisture.Type: ApplicationFiled: August 19, 2010Publication date: February 23, 2012Inventor: John K.

Publication number: 20120023986Abstract: A refrigerator includes a heat transfer unit, which transfers heat generated from a machine room within a refrigerator main body to a periphery of a home bar so as to remove dew formed at the periphery of the home bar, and an insulating unit for surrounding an outer circumference of the heat transfer unit. The refrigerator further includes a heating unit installed to be thermally conductive with the heat transfer unit, and a non-conductive cover for covering the heat transfer unit and the heating unit. Consequently, waste heat generated from the machine room, other than a separate power supply unit, can be used to prevent dew formation at the periphery of the home bar, so as to remarkably reduce power consumption.Type: ApplicationFiled: July 29, 2011Publication date: February 2, 2012Inventors: Sunam Chae, Juyeong Heo, Sung Jhee, Chanho Jeon
