Patent number: 6813894Abstract: There are provided a heat pump having a high COP and a dehumidifying apparatus arranged in a compact size. The heat pump has a pressurizer 260 for raising a pressure of a refrigerant 260, an evaporator 210 for cooling a low-temperature heat source fluid A with heat of evaporation of the refrigerant to be pressurized, a condenser 220 for heating a high-temperature heat source fluid B with heat of condensation of the pressurized refrigerant, and a first heat exchanger 300a for exchanging heat between the low-temperature heat source fluid A upstream of the evaporator 210 and a cooling fluid. The first heat exchanger 300a has a first compartment 310 through which the low-temperature heat source fluid A flows, a second compartment 320 through which the cooling fluid flows, and refrigerant passages 251A1-A9, 252A1-A9 extending through the first compartment and the second compartment.Type: GrantFiled: June 20, 2002Date of Patent: November 9, 2004Assignee: Ebara CorporationInventor: Kensaku Maeda

Patent number: 6813895Abstract: A vapor compression system includes a compressor, a gas cooler, an expansion device, and an evaporator. Refrigerant is circulated through the closed circuit cycle. Preferably, carbon dioxide is used as the refrigerant. Adaptive control is employed to optimize the coefficient of performance of the vapor compression system. As the system changes over time, a model that operates the system is modified. The model is determined by an adaptive control algorithm including variable coefficients. As the model changes, the variables of the adaptive control algorithm change. A control of the gas cooler is then adjusted to regulate the high pressure of the system, and therefore the coefficient of performance. In a first example, Least Mean Squares (LMS) is used to modify the variables of the adaptive control algorithm to optimize the coefficient of performance. In a second example, the coefficient of performance is optimized by a slowly varying periodic excitation method.Type: GrantFiled: September 5, 2003Date of Patent: November 9, 2004Assignee: Carrier CorporationInventors: Bryan Eisenhower, Christopher G. Park, Pengju Kang, Alan Finn, Tobias Sienel

Patent number: 6813896Abstract: A power bus, connected to a 24V isolated power supply, is provided in a refrigerator where removable shelves can be selectively connected to it. Each shelf has a user interface and a circuit to control a microenvironment within the refrigerator, partially bounded by the shelf. Data between the shelf and a control circuit in the refrigerator can be transmitted over the power bus, or by other methods.Type: GrantFiled: July 30, 2003Date of Patent: November 9, 2004Assignee: Whirlpool CorporationInventors: Donald E. Janke, Steven J. Kuehl, Michele E. Emig, Wendeline Rodriguez

Patent number: 6813897Abstract: A primary power system and a secondary power system are operable to supply power to at least one cooling system component in a cooling system. The amount of power supplied by the primary power system and the secondary power system to the at least one cooling system component is controlled based on an operating level threshold for the at least one cooling system component.Type: GrantFiled: July 29, 2003Date of Patent: November 9, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Cullen E. Bash, Chandrakant D. Patel, Gopalakrishnan Janakiraman, Keith Istvan Farkas

Patent number: 6813898Abstract: An electrically powered air freight container (1) includes an insulated housing (2) and a refrigeration unit (3). The refrigeration unit (3) is powered by a voltage and frequency converter which receives electrical power either aircraft generated from either an airport ground source of power or an aircraft source of power which is appropriate to power the refrigeration unit (3) The refrigeration unit (3) is powered by a voltage and frequency converter which receives either airport power at 240 volt or 115 volt or aircraft power at 115 volt (400 Hz) and converts the supply to a voltage and frequency appropriate to power the refrigeration unit (3). The air contained in the housing is free to expand in the event of rapid depressurisation by the provision of blow out covers (19) which close ducts (15).Type: GrantFiled: June 16, 2003Date of Patent: November 9, 2004Inventors: Leslie John Lindsay, Christopher Robin Hill
