  • the liquid passing through the condenser no longer absorbs heat, or absorbs heat at a very reduced capacity, and thus provides little or no utility in the condenser. That is, any surface area in the condenser that is not utilized by the vaporized refrigerant reduces heat absorption from the fluid flow.
  • a condenser includes a plurality of conduits extending along an axis and spaced one from another. Each of the plurality conduits includes a first end that extends to a second end.
  • a condenser inlet is fluidly connected to the plurality of conduits, and a condenser outlet is fluidly connected to the plurality of conduits.

  • the phase separator includes at least one reservoir configured and disposed to contain vaporized refrigerant and liquid refrigerant, the at least one reservoir is fluidly connected to the condenser outlet.
  • a method of separating liquid refrigerant and vaporized refrigerant in a condenser includes guiding vaporized refrigerant into a condenser inlet, passing the vaporized refrigerant through a plurality of conduits, condensing a portion of the vaporized refrigerant to form liquid refrigerant, passing a combined flow of vaporized refrigerant and liquid refrigerant into at least one reservoir, separating the vaporized refrigerant from the liquid refrigerant, passing the vaporized refrigerant to remaining ones of the plurality of conduits, and directing the liquid refrigerant from the reservoir to a condenser outlet bypassing the remaining ones of the plurality of conduits.

Chacun des différents conduits comprend une première extrémité qui s'étend jusqu'à une seconde extrémité. Une entrée du condenseur est raccordée fluidiquement aux différents conduits et une sortie du condenseur est raccordée fluidiquement aux différents conduits. Un séparateur de phase est raccordé à au moins deux des différents conduits en aval de l'entrée du condenseur et en amont de la sortie du condenseur. Le séparateur de phase comprend au moins un réservoir conçu et disposé pour contenir du fluide frigorigène vaporisé et du fluide frigorigène liquide, le ou les réservoirs étant raccordés fluidiquement à la sortie du condenseur.
