Abstract: A refrigeration appliance has a cabinet having a first compartment, a second separate compartment and a refrigeration system including a compressor, an evaporator and a condenser. The evaporator is associated with the first compartment to lower a temperature of the first compartment air. A heat exchanger is exposed to the temperature of the first compartment and has a surface area exposed to second compartment air. An air moving device is associated with the second compartment to direct a flow of second compartment air over the heat exchanger surface area and circulate the second compartment air within the second compartment. The cabinet, compartments and heat exchanger are configured such that first compartment air is completely isolated from second compartment air.

Abstract: A refrigerator, including a cabinet having top, bottom, rear and opposing side walls that collectively define a freezer compartment and a fresh food compartment, employs a cooling system and an air plenum to deliver a cooling air flow into the freezer and fresh food compartments. The air plenum includes a variable position air damper having a first, substantially straight portion and a second arcuate portion that forms an air scoop. The air damper is slidably mounted within the air plenum between first and second positions. The variable position air damper is selectively arranged in the first position to efficiently deliver a volume of the cooling air flow into the freezer compartment, the second position to deliver the cooling airflow into the fresh food compartment or in an infinite number of intermediate positions to deliver the cooling airflow into both compartments.

Abstract: A seal assembly for a regenerative heat exchanger can include a primary sealing member with a mounting base and a flexible contact portion that defines a first distance between a proximal edge of the mounting base and a contact edge of the flexible contact portion, the first distance being generally constant along the length of the primary sealing member. The seal assembly can also include a second member with a mounting portion and a cantilevered portion that defines a second distance between a proximal edge of the mounting portion and a distal edge of the cantilevered portion, the second distance being generally constant along the length of the second member. The first distance is greater than the second distance by a predetermined amount so as to limit the preload flexure of the flexible contact portion against a sector plate of the heat exchanger when the seal assembly is installed in the regenerative heat exchanger.

Abstract: A method for controlling a vehicle HVAC system to automatically defog a windshield glass and to prevent fogging or condensation of the windshield glass. In-cabin air temperature and relative humidity are measured and used to determine a dewpoint. Further, ambient or outside temperature is measured. If windshield wipers are being used or if the cabin air temperature is less than a predetermined temperature, the ambient air temperature value is used as a glass temperature, otherwise the glass temperature is determined from the ambient air temperature and vehicle speed. A fog margin, which is a measure of the likelihood of fog formation, is based upon the difference between dewpoint and the windshield glass temperature. The fog margin is used to control the HVAC system to anticipate and respond to potential fogging conditions.

Abstract: A system and method are presented for managing the supply of energy to heating and cooling devices to reduce the thermal flux and overshoot in buildings having heating and cooling devices that are sized for extreme temperature demands, but which operate inefficiently for moderate conditions. The system interposes a control module between sensor devices and heating or cooling devices, to filter the signals from the sensor devices calling for heating or cooling according to one or more on/off routines. The control module defers the sending of signals activating or deactivating heating or cooling devices, thus allowing for moderating of ambient conditions between the initial demand from the sensor devices and the supply of heating or cooling by the heating or cooling devices.
