Publication number: 20130111933Abstract: A refrigerator using a non-azeotropic refrigerant mixture (NARM) and a control method thereof. The refrigerator reduces the rotational speed of a freezing chamber fan or stopping the freezing chamber fan for a designated time, and/or increasing the rotational speed of a compressor in a simultaneous freezing/refrigerating operation mode of an NARM cycle as compared to a freezing operation mode, and may thus decrease evaporation latent heat of a refrigerant consumed by a freezing chamber evaporator and relatively increase evaporation latent heat of the refrigerant usable in a refrigerating chamber evaporator without increase in a charging amount of the refrigerant, thereby preventing over-charging due to increase in the charging amount of the refrigerant and reducing cycling loss.Type: ApplicationFiled: November 8, 2012Publication date: May 9, 2013Applicants: KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATION, SAMSUNG ELECTRONICS CO., LTD.Inventors: SAMUSNG ELECTRONICS CO., LTD., KOREA UNIVERSITY RESEARCH AND BUSINE

Publication number: 20130111934Abstract: A system has a compressor (22, 412). A heat rejection heat exchanger (30) is coupled to the compressor to receive refrigerant compressed by the compressor. The system has a heat absorption heat exchanger (64). The system includes a separator (170) comprising a vessel having an interior. The separator has an inlet, a first outlet, and a second outlet. An inlet conduit may extend from the inlet and may have the conduit outlet positioned to discharge an inlet flow into the vessel interior to cause the inlet flow to hit a wall before passing to a liquid refrigerant accumulation in the vessel.Type: ApplicationFiled: July 20, 2011Publication date: May 9, 2013Applicant: Carrier CorporationInventors: Jinliang Wang, Parmesh Verma, David P.

Publication number: 20130111935Abstract: A system (200; 250; 270) has a compressor (22), a heat rejection heat exchanger (30), first (38) and second (202) ejectors, first (64) and second (220) heat absorption heat exchangers, and a separator. The ejectors each have a primary inlet (40, 204) coupled to the heat rejection exchanger to receive refrigerant. A second heat absorption heat exchanger (220) is coupled to the outlet of the second ejector to receive refrigerant. The separator (48) has an inlet (50) coupled to the outlet of the first ejector to receive refrigerant from the first ejector. The separator has a gas outlet (54) coupled to the secondary inlet (206) of the second ejector to deliver refrigerant to the second ejector. The separator has a liquid outlet (52) coupled to the secondary inlet (42) of the first ejector via the first heat absorption heat exchanger to deliver refrigerant to the first ejector.Type: ApplicationFiled: July 20, 2011Publication date: May 9, 2013Applicant: CARRIER CORPORATIONInventors: Jiang Zou, Hongsheng Liu, Parmesh Verma Verma, Thomas D.

Publication number: 20130111936Abstract: A refrigerator with individualized locking drawers is similar in size and shape to a standard refrigerator, with a plurality of drawers in the refrigerator compartment that can be personalized. The drawers have a locking mechanism, a name placard displaying the user's name, a use frequency display, and a spoilage display. A digital control interface on the refrigerator door allows users to register for and manage drawers, and a network connection device allows users to manage their drawer through a website interface or a mobile application. A community storage shelf below the individual drawers and shelves on the inside face of the refrigerator door provides space for large items or community items, and a freezer compartment below the refrigerator compartment provides storage for items that require lower temperatures than the refrigerator compartment.Type: ApplicationFiled: October 23, 2012Publication date: May 9, 2013Inventor: Timothy John Olson

Publication number: 20130111938Abstract: A heat exchanger with at least one cooling segment having a first, a second, and a third portion. A first heat carrier flow path, through which a first heat carrier medium flows, extends through the first portion. A second heat carrier flow path, through which a second heat carrier medium flows, extends through the second portion. A first coolant flow path, through which a first coolant medium flows, extends through the third portion. The heat exchanger comprises at least one cooling body, a second coolant medium flowing through a second coolant flow path extending through the cooling body. The first and the second heat carrier flow paths are thermally coupled, respectively, to the first and the second coolant flow path, to discharge heat energy of at least one of the first and the second heat carrier medium to at least one of the first and the second coolant medium.Type: ApplicationFiled: November 1, 2012Publication date: May 9, 2013Applicant: AIRBUS OPERATIONS GMBHInventor: Airbus Operations GmbH
