  • Refrigerator system for two-compartment cooling
    Patent number: 5235820
    Abstract: A refrigeration system for refrigerators having two or more compartments maintained at different temperatures comprises separate cycles for each compartment, each cycle in turn comprising separate evaporator means, heat exchanger means and compressor. To provide for cycle separation, the condenser may be split into separate units, connected by phase separators where appropriate. The system is particularly designed for use in connection with mixed, nonazeotropic refrigerants.
    Type: Grant
    Filed: November 19, 1991
    Date of Patent: August 17, 1993
    Assignee: The University of Maryland
    Inventors: Reinhard Radermacher, Dongsoo Jung
  • Refrigeration system
    Patent number: 5207077
    Abstract: A dual evaporator refrigeration system cooling separate compartments at different temperatures employs specific combinations of environmentally safe refrigerants as working fluids. Each of the working fluids is a binary or ternary combination which yields enhanced efficiency in the dual evaporator system.

  • Advanced vapor compression heat pump cycle utilizing non-azeotropic working fluid mixtures
    Patent number: 4724679
    Abstract: A process for transferring heat from a lower temperature material to a higher temperature material utilizes a non-azeotropic working fluid mixture and overlapping temperatures in the evaporator (desorber) and condenser (absorber). An apparatus for effectuating the process thermally couples the evaporator (desorber) and condenser (absorber).
