Patent number: 8800309Abstract: A method of automatically detecting an anomalous condition relative to a nominal operating condition in a vapor compression system. An expected input power function in the form of a hyperplane is calculated based on three temperature readings: an intake temperature from an intake area of the condenser unit, a return temperature from an intake area of an evaporator unit, and a supply temperature from a supply output area of the evaporator unit. The function produces an estimate of the expected input power consumed by the compressor unit, and this expected input power is compared with an actual input power measured from the compressor unit.

Patent number: 8800312Abstract: In a storage compartment (124), storage spaces having different mist concentrations are formed such that effects of a mist is more efficiently utilized to provide a refrigerator with improved usability. The storage compartment (124) includes a first storage unit (164) that has a high mist concentration. The first storage unit (164) includes a spray device (167) and is disposed in a position outside an air path of cool air between a discharge port (152) through which the cool air flows in from outside the storage compartment (124) and a suction port (149) through which the cool air is discharged to outside the storage compartment (124). Thus, mist concentration inside the first storage unit (164) can be increased.Type: GrantFiled: August 26, 2010Date of Patent: August 12, 2014Assignee: Panasonic CorporationInventors: Toyoshi Kamisako, Kenichi Kakita, Kumiko Okubo, Mitoko Ishita, Satomi Ueda

Patent number: 8800313Abstract: A water circulation system associated with a refrigerant cycle that includes an intermediate heat exchanger having a triple-pipe shape in which three independent flow passages are formed by three pipes having a concentric axis and different diameters. Accordingly, three fluids flowing through the three independent flow passages can exchange heat with each other at the same time through the intermediate heat exchanger and heat exchange capacity of the intermediate heat exchanger can selectively be varied.Type: GrantFiled: March 23, 2010Date of Patent: August 12, 2014Assignee: LG Electronics Inc.Inventors: Hyoung Suk Woo, Jae Sun Song

Patent number: 8800314Abstract: An ice cube maker includes an ice-making compartment having side walls, at least one rod-shaped conductor extending distally into the compartment through one of the side walls, and a cooling device for cooling the conductor to a temperature sufficient to form ice on the conductor. A misting system includes a reservoir for water and a nebulizer for creating a liquid mist from water in the reservoir and introducing the liquid mist into the ice-making compartment so that a portion of the liquid mist freezes on the conductor to form a cup-shaped ice cube thereon. A return conduit connects a drain of the ice-making compartment and the reservoir for transferring liquid mist not freezing on the conductor to the reservoir.Type: GrantFiled: October 22, 2010Date of Patent: August 12, 2014Assignee: General Electric CompanyInventor: Alan Joseph Mitchell

Patent number: 8800315Abstract: Provided is a refrigerator. In the refrigerator, a water supply unit connected to a water supply passage to temporarily store the supplied water, thereby stably supplying water is disposed above an ice making apparatus. Also, since water having a reduced pressure is supplied into the ice making apparatus, the water may be stably supplied into the ice making apparatus.Type: GrantFiled: July 13, 2011Date of Patent: August 12, 2014Assignee: LG Electronics Inc.Inventors: Yonghyun Kim, Ilwook Joung, Siyeon An, Byoungjun Lee

Patent number: 8800317Abstract: The present invention is a geometrically optimized beverage cooler, which positions fluid-filled containers (bottles, cans, vials, syringes, etc.) in an angled, upright, and evenly spaced position for serving and display. The device uniformly distributes ice and cold water around each bottle to maximize the effective cooling capacity of a given quantity of ice, thus reducing the amount of ice needed and the weight of the device during transport. Various embodiments of the apparatus include an ergonomically and structurally reinforced handle and an insulating lid having complementary contours.Type: GrantFiled: April 15, 2010Date of Patent: August 12, 2014Inventors: Milton Dallas, Russell Robers
