Definitions

  • the present invention relates to portable air-conditioning equipment for living areas, according to the preamble of Claim 1 (see US-A- 4 138 859 and US-A-5 313 806).
  • the problem upon which the present invention is based is that of devising equipment of the -type specified which has structural and functional characteristics such as to overcome the aforementioned disadvantage.
  • portable air-conditioning equipment for living areas is generally indicated 1.
  • the equipment 1 comprises a compressor 2 fixed in a pipe 3, and an expansion device 4 fixed in a pipe 5.
  • the pipes 3 and 5 connect two heat exchangers 6 and 7 so as to create a refrigeration circuit 8 in which a suitable refrigerant circulates, the heat exchanger 6 constituting an evaporator and the heat exchanger 7 constituting a condenser.
  • Respective air-movement means 9 and 10 are associated with the two heat exchangers 6 and 7.
  • a liquid-vapour separator 11 associated with the compressor 2 is fixed in the pipe 3 on the same side as the suction opening of the compressor to prevent the refrigerant from reaching the compressor in the liquid state and damaging it.
  • the expansion device 4 is constituted by two capillary tubes both indicated 12.
  • the refrigeration circuit 8 is divided into an internal unit 13 and an external unit 14 which are portable and structurally independent, and a flexible connection element 15 for connection between the internal and external units.
  • the internal unit 13 houses the evaporator 6 with the electric fan 9 and the external unit 14 houses the condenser 7 with the electric fan 10, as well as the compressor 2 with its liquid-vapour separator 11.
  • the pipe 3 is divided into a portion 16 housed in the internal unit 13, extending from the evaporator to the connection element, a portion 17 housed in the connection element, a portion 18 housed in the external unit 14, extending between the connection element and the compressor and carrying the separator, and a portion 19 extending from the compressor to the condenser.
  • the portions 16, 17 and 18 constitute suction pipes, whereas the portion 19 constitutes a pressure pipe.
  • the pipe 5 is divided into a portion 20 extending between the condenser and the connection element and housed in the external unit 14, a portion 21 housed in the connection element, and constituted by the two capillaries 12, and a portion 22 extending between the connection element and the evaporator, and housed in the internal unit 13.
  • the flexible connection element 15 comprises an outer sheath 23 defining two longitudinal cavities 24 and 25 separated by a partition 26.
  • the portion 17 of the pipe 3, the two capillaries 12 and two electric cables 27 extend into the cavity 24.
  • a condensate drain pipe 28 extends into the cavity 25.
  • the sheath 23 has ribs 29 which project into the cavity 24 and are of a size such as to hold the portion 17 of the pipe 3 in the centre of the cavity, forming a space 30.
  • the capillaries 12 and the electric cables 27 are housed in the space 30 between adjacent ribs 29, close to both the sheath 23 and the portion 17 of the pipe 3.
  • the electric cables 27 are formed by conductors having small cross-sections so as to constitute electrical resistances for heating the space.
  • the external unit 14 has a handle 31 at the top for its movement, an internal space 32 formed below the condenser and the electric fan for housing the compressor 2 which is of the type with a horizontal axis X-X and, finally, wheels 33 at the bottom so that it can be wheeled about.
  • the internal unit has shown a reduction in noise of about 10 dB inside the premises to be air-conditioned, in operation.
  • connection element has an external temperature such that it is dry and wholly free from condensation of ambient moisture.
  • the main advantage of the equipment lies in the unusually high degree of comfort achieved even at night because the internal unit is extremely quiet owing to the absence of the compressor.
  • connection element The complete absence of condensation of ambient moisture on the connection element should also be noted.
  • the equipment is compact and easy to handle.
  • the weight of the external unit is well balanced relative to the handle and the wheels enable it to be transported without effort.
  • the equipment according to the invention is also advantageous from the point of view of energy saving since the heat dissipated by the compressor is dispersed to the exterior and not inside the premises to be air-conditioned.
