Definitions

  • the present patent relates to an evaporator-condenser battery, especially for air conditioners of the removable type and in general for apparatuses operating on the basis of a refrigerating circuit
  • the ambient air is conducted through two exchangers, which con­stitute, respectively, the evaporator and the condenser of the cooling circuit, the air being cooled and dehumidified in the evaporator and then fed into the room to be conditioned, and the air being, in the condenser, heated by the effect of the condensation, humidified by the re-evaporation of the condensate water coming from the evaporator and then fed out of doors by means of a pipe, with advantage a flexible pipe, inserted, for example, between the half-closed leaves of a window.
  • the re-evaporation of the condensate on the condenser is important because, requiring a certain quantity of heat, it allows the quantity of ambient air discharged to the outside to be reduced to a minimum, with a resultant reduced return into the room of untreated air (better overall efficiency) and with a reduction of the dimensions of the pipe leading out of doors to greatly reduce values.
  • the re-evaporation furthermore simplified the use of the apparatus, by eliminating the problem of recovering the condensate.
  • the objective of the present invention consists in providing a com­posite evaporator-condenser battery which shall make possible the realization of an air conditioning apparatus, or other apparatus oper­ating on the basis of a cooling or refrigerating circuit, which shall have a decidedly more simple and efficient construction than the con­ventional devices.
  • Another objective of the invention consists of providing an apparatus, a conditioner or the like, equipped with such a battery so as to have relatively limited dimensions and propor­tionally reduced production costs.
  • the battery especially for air conditioners of the movable type and in general for apparatuses operating on the basis of a refrigerating cir­cuit, according to this invention, is characterized by the fact of being constituted of a plurality of fins, constituting as a whole a single package, through which passes a first series of coiled pipes connected to the delivery side of a compressor, and a second series of coiled pipes connected to the return of said compressor, the two series of pipes being conventionally connected to one another by an expansion device and the second series of pipes, when the battery is in a working position, being disposed above the first series of pipes.
  • the composite evaporator-­condenser battery is referenced generally 1 and is conventionally asso­ciated with a compressor 2, forming a part of a conventional refrigera­ting circuit.
  • the battery 1 is constituted of a plurality of fins 3 side-by-side, constituting as a whole a package, through which passes a first series of coiled pipes 4, connected to the delivery 5 of the compressor 2, and a second series of coiled pipes 6, connected - by means of the return 7 - to said compressor 2.
  • the last length of the coiled pipe constituting the first series 4 is connected, by means of an expansion device 8, to the first length of the coiled pipe constituting the second series 6.
  • the first series of pipes 4 constitutes the condenser of the refrigerating circuit and the second series of pipes 6 constitutes the evaporator of said refrigerating circuit.
  • the battery 1 - in the case of its use in an air conditioner of the removable type and referenced generally 9 - is disposed above a fan unit 10 in a vertical position or near to the vertical. With this vertical, or almost vertical position, the con­densate which forms on the cold zone of the evaporator in the uppermost part of the battery 1 flows by gravity along the fins 3, moving gradu­ally and uniformly over the hot surface of said fins 3 of the battery 1, situated in correspondence with the condenser, which consequent re-­evaporation.
  • the fan 10 sucks in the room air through the opening 11, conducts it through the battery 1 and the portion of the room air passing through the condenser zone 4 of said battery is discharged, hot, to the outside through the opening 12.
  • the portion of the room air passing through the evaporator zone 6 of said battery 1 is returned, cooled, into the room through the aperture 13.
  • Figure 5 is similar to Figure 2, the only difference being that the fins 3 of the battery 1 are not continuous between the upper zone (evaporator) and the lower zone (condenser), but are separ­ated by a small space 14, thereby forming an upper group of fins 3′ and a lower group of fins 3 ⁇ , the two groups - in each case - being so disposed as to permit the desired transfer of the condensate from the evaporator part of the battery to the condenser part in order to achieve the re-evaporation of same.
