Abstract: An apparatus includes a mechanical refrigeration cycle arrangement having a working fluid and an evaporator, a condenser, a compressor, and an expansion device, cooperatively interconnected and containing the working fluid. The apparatus also includes a drum to receive clothes to be dried, a duct and fan arrangement configured to pass air over the condenser and through the drum, a sensor located to sense at least one parameter, and a controller coupled to the sensor and/or the compressor. The parameter(s) includes at least one of temperature of the working fluid, pressure of the working fluid, and power consumption of the compressor. The controller is operative to monitor, as a function of time, the parameter(s), determine whether the parameter(s) reaches a predetermined decision condition; and, if the parameter(s) reaches the predetermined decision condition, power down the mechanical refrigeration cycle at least by causing the compressor to shut off.

Abstract: An apparatus includes a mechanical refrigeration cycle arrangement having a working fluid and an evaporator, a condenser of adjustable surface area, a compressor, and an expansion device, cooperatively interconnected and containing the working fluid. The apparatus also includes a drum to receive clothes to be dried, a duct and fan arrangement configured to pass air over the condenser and through the drum, a sensor located to sense at least one parameter, and a controller coupled to the sensor, condenser and/or the compressor. The controller is operative to adjust the condenser to increase surface area during a steady state drying rate period of the cycle, and adjust the condenser to decrease surface area during a start transient period of the cycle, wherein adjusting the condenser to decrease surface area during a start transient period of the cycle accelerates the start transient period of the cycle.

Abstract: A household refrigerator having a freezer compartment with a rear wall, top wall, side walls, bottom wall and an open front. An evaporator unit is mounted in a space in front of the rear wall of the freezer compartment and there is a vertical panel separating the evaporator unit from the rest of the freezer compartment to form an evaporator compartment between the panel and rear wall. The bottom wall of the freezer compartment has a plurality of upwardly open grooves extending from the front section of the freezer compartment under the vertical panel and into the evaporator compartment. A cover is hingedly connected to the panel for movement to a raised position above the bottom wall for access to the grooves in the bottom wall for cleaning and to a lowered position horizontal to the bottom wall to provide a flat level shelf area for storage items in the freezer compartment.
