Patent number: 7458418Abstract: A heat pump system includes a compressor, a heat rejecting heat exchanger, an expansion device, and a heat accepting heat exchanger. A storage tank stores the water that cools the refrigerant in the heat rejecting heat exchanger. A mechanical interface plate positioned between a hot water reservoir and a cold water reservoir in the storage tank reduces heat transfer between the hot water and the cold water. During a water heating mode, cold water from the cold reservoir flows into the heat sink to cool the refrigerant in the heat rejecting heat exchanger. As the water exchanges heat with the refrigerant, the water is heated in the heat sink, exits the heat sink, and flows into the hot reservoir of the storage tank. During a water discharge mode, the hot water in the hot reservoir is removed from the storage tank and flows into a hot water discharge. Cold water from a water source flows into the cold reservoir of the storage tank to refill the storage tank.Type: GrantFiled: May 16, 2005Date of Patent: December 2, 2008Assignee: Carrier CorporationInventor: Tobias H. Sienel

Patent number: 7380408Abstract: An aircraft is provided with an integrated galley refrigeration unit and vehicle cabin air conditioning packet. A control selectively determines whether the provision of cooled air into an air cooled galley takes precedent over the provision of cooled air into the passenger cabin. Valving is provided to selectively provide cold fluid to a recirculation air heat exchanger, which supplies supplemental cooled air for delivery into the passenger cabin. This refrigeration air heat exchanger is utilized when precedent is given to providing cooled air to the cabin. On the other hand, the valve is maintained in an off position when it is determined that the air cooled galleys should take precedent.Type: GrantFiled: December 20, 2005Date of Patent: June 3, 2008Assignee: Hamilton Sunstrand CorporationInventors: Thomas Zywiak, Diane Drew

Patent number: 7269007Abstract: A heat sink uses a pump assembly to generate a magnetic field. Flow directions of electrically and thermally conductive liquid flowing through multiple pipes that go through the pump assembly are dependent on an orientation of the magnetic field and/or the direction of electrical current induced across flowing fluid in the magnetic field. In such a manner, cool liquid may be directed toward a heat source and warmer liquid may be directed to flow away from the heat source, where heat transfer occurs between the liquid and the heat sink. Additional pump assemblies that generate separate magnetic fields may be used to increase fluid flow volume, thereby increasing heat transfer away from the heat source.Type: GrantFiled: September 6, 2005Date of Patent: September 11, 2007Assignee: Sun Microsystems, Inc.Inventor: Chien Ouyang
