Definitions

  • refrigerant In a typical refrigeration system, refrigerant circulates continuously through a closed circuit.
  • circuit refers to a physical apparatus whereas the term “cycle” as used herein refers to operation of a circuit, e.g., refrigerant cycles in a refrigeration circuit.
  • refrigerant refers to refrigerant in a liquid, vapor and/or gas form. Components of the closed circuit cause the refrigerant to undergo temperature/pressure changes. The temperature/pressure changes of the refrigerant result in energy transfer.
  • Typical components of a refrigeration system include, for example, compressors, condensers, evaporators, control valves, and connecting piping. Details with regard to some known refrigeration systems are set forth in Baumeister et al., Standard Handbook for Mechanical Engineers, McGraw Hill Book Company, Eighth Edition, 1979, beginning at page 19-6.
  • the present invention is believed to have greatest utility in refrigeration systems having more than one evaporator, such as a refrigeration system including a fresh food evaporator and a freezer evaporator. More particularly, one embodiment of the present invention comprises disposing a capillary tube, connected to the inlet of the freezer evaporator, in a heat transfer relationship with the freezer evaporator suction line, e.g., a conduit connected between the outlet of the freezer evaporator and the inlet of the compressor unit.
  • a capillary tube connected to the inlet of the freezer evaporator, in a heat transfer relationship with the freezer evaporator suction line, e.g., a conduit connected between the outlet of the freezer evaporator and the inlet of the compressor unit.
  • the first capillary tube 106 is disposed in a counterflow heat exchange arrangement with the conduits 120 and 130. Thermal contact is achieved, for example, by soldering the exterior of the capillary tube 106 and a portion of the exterior of the conduits 120 and 130 together side-by-side.
  • the capillary tube 106 is shown as being wrapped around the conduits 120 and 130 as a schematic representation of a heat transfer relationship. The heat transfer occurs in a counterflow arrangement, i.e., the refrigerant flowing in the capillary tube 106 proceeds in a direction opposite to the flow of refrigerant in the conduits 120 and 130.
  • FIGS 4A-B respectively, illustrate temperature-enthalpy diagrams.
  • the diagram for Figure 4A is for a refrigeration circuit similar to the circuit 100 illustrated in Figure 1 but not having the capillary tube 122 and the conduit 130 disposed in a heat transfer configuration.
  • the diagram in Figure 4B is for the refrigeration circuit 100 illustrated in Figure 1 which, as shown, includes one embodiment of the present heat transfer configuration, i.e., the capillary tube 122 and the conduit 130 are disposed in a heat transfer configuration.
  • Figure 7 illustrates a third embodiment of a refrigeration system 400 including a third embodiment of the present heat transfer configuration.
  • the refrigeration system 400 comprises a first compressor unit 402 and a second compressor unit 404, the outlet of the first compressor unit 402 being connected to the inlet of the second compressor unit 404.
  • a first capillary tube 406 is coupled to the outlet of the second compressor unit 404, and the outlet of the first capillary tube 406 is coupled to the inlet of a first expansion device 408.
  • the outlet of the first expansion device 408 is coupled to the inlet of the first evaporator 410, and the outlet of the first evaporator 410 is coupled to the inlet of a phase separator 412.
