Definitions

  • This invention relates to a transferable room air conditioner of split type.
  • This type of air conditioner is known to consist of a condenser unit located outside the room to be air conditioned and comprising an electrically operated fan, condenser and condensate disposal device, and a motor-driven evaporator unit located inside said room and comprising an electrically operated fan, compressor and evaporator, said two units being connected together by a flexible cord through which the pipes for the refrigeration medium, generally freon, the electrical cables for powering the external fan and the pipe for the condensed water led to the outside pass.
  • An object of the invention is to provide a transferable room air conditioner of split type which is so configured as to reduce the dimensions and weight of the external unit to a minimum and thus obviate the drawbacks of conventional air conditioners of this type.
  • the transferable room air conditioner of split type comprises an internal unit containing an electrically operated fan, a compressor and an evaporator, and an external unit containing an electrically operated fan, said units being connected together by a flexible cord through which the pipes for the refrigeration medium and the electrical cables pass, and is essentially characterised in that the condenser is divided into two parts, of which a first part is located in the internal unit and the second part is located in the external unit, so enabling the dimensions and weight of said external unit to be substantially reduced, and at the same time improving transferability of the entire assembly.
  • the air conditioner consists conventionally of an internal unit indicated overall of 1, and an external unit indicated overall by 2, said two units being connected together by a flat flexible cord 3.
  • the refrigeration medium is condensed in two separate condensers, namely a first condenser 4 located in the internal unit 1 and a second condenser located in the external unit 2, in contrast to conventional air conditioners of this type, which comprise a single condenser located in the external unit.
  • the internal unit 1 houses an electrically operated fan 6 and a compressor 7, the fan drawing air from the room to be air conditioned and recycling it cooled and dehumidified to the same room after passing through an evaporator 8. A part of the air delivered by said fan is passed through the first condenser 4 to cool it and is then discharged to the outside through the small-diameter flexible tube 9.
  • the condenser 4 is provided with means (not shown) for collecting and re-evaporating the water condensed by the evaporator 8.
  • the second condenser 5 is located in the external unit in front of an electrically operated fan 10 which draws air from in front of said unit 2 to cool said second condenser 5.
  • the size of this second condenser and the air quantity required for its cooling are considerably less than in the case of conventional arrangements, so enabling the dimensions and weight of the external unit to be drastically reduced (down to about 1/3 of conventional units), which can therefore be designed so as no longer to require air to be drawn in from its rear.
  • the external unit thus becomes much more manageable and simple to position as it is now sufficient merely to stand it on the balcony or window sill, and allow the cord 3, now smaller than the conventional because it no longer carries the water tube, and the small flexible tube 9 for discharging the hot air which has cooled the inner condenser part 4 and also removes the condensate which has evaporated on it, to pass between the pulled-to casements.
  • This air also represents the normal room air change.
