Definitions

  • atmospheric air conditioners are known in which the evaporator assembly is physically separated from the condenser assembly, which is located outside, the connection between the two assemblies being made by a pair of semi-rigid pipes able to resist high pressure, through which a refrigerant fluid, normally a synthetic organic chloro-fluoro carbon or briefly CFC compound known as freon, is circulated by a compressor.
  • a refrigerant fluid normally a synthetic organic chloro-fluoro carbon or briefly CFC compound known as freon
  • the double CFC-proof pipe forming the connection between the internal evaporator assembly and the external condenser assembly has a length necessarily limited to a few metres, and cannot be longer because of excessive pressure drop.
  • the condensate formed on the evaporator has either to be collected by inconvenient trays or evacuated through a specific pipe, which complicates installation.
  • the object of the present invention is to obviate these drawbacks.
  • the further object of externally evacuating the condensate which forms on the evaporator without using specific additional piping for it is achieved by forming in the air conditioning unit comprising the evaporator and condenser a tray for collecting the condensed air moisture which forms on the evaporator, this condensate being discharged into an open-top vessel forming part of the condenser cooling water circuit.
  • the reference numeral 1 indicates the unit comprising the evaporator 101, condenser 102 and relative compressor 103 and expansion valve 104, to be installed within the room to be air conditioned and mobile on wheels 6.
  • the reference numeral 2 indicates the outlet grille for the conditioned air.
  • the reference numeral 3 indicates the electrically operated water circulation pump of the condenser cooling circuit
  • 4 indicates an open-top vessel forming part of said circuit, which comprises the water/refrigerant gas heat exchanger 5
  • the reference numeral 7 indicates a female socket for electrical connections
  • 7' indicates the corresponding plug connected to the multi-core electric cable 11.
  • the reference numerals 8 and 8' indicate respectively the female and male part of a known sealing connector for water hoses, which can be disconnected and connected at will by a simple operation to secure the delivery hose 12, and 9 and 9' indicate a similar connector for the return hose 13.
  • the reference numeral 10 indicates a flexible multiple duct consisting of a covering sheath 16 which contains the two said hoses 12 and 13 and the multi-core electric cable 11.
  • the reference numeral 14 indicates the second unit comprising the cooling water/air heat exchanger installed outside the room to be conditioned, and 15 indicates the grille through which the air passes.
  • the reference numeral 17 indicates a tray positioned below the evaporator (this latter not shown in the figure) and arranged to collect the condensate dripping from the evaporator to then be conveyed into the underlying vessel 4.
  • the reference numeral 18 indicates an electrically operated level controller connected by an electric lead 11' to the solenoid valve 19, the lead 11' being one of the leads forming part of the multi-core cable 11.
  • the reference numeral 21 indicates a pipe which branches from the cooling water circuit to feed via the solenoid valve 19 a spray pipe which sprays water droplets onto the fins of the water/air heat exchanger 22.
  • reference numeral 23 indicates an electrically driven fan for the forced cooling of said finned heat exchanger 22.
  • the condensate from the cooled air, which collects in the tray 17, results in a level increase in the vessel 4 after a certain time of operation, so that the electrical level controller operates.
  • the solenoid valve 19 then opens to remove the excess water from the circuit by spraying it onto the finning of the heat exchanger 22 to cause it to evaporate, given the high temperature of this finning. Hence the normal level is restored in the vessel 4, until further intervention of the level controller 18.
  • the fan 23 is powered via electric lines contained within the multi-core cable 11, so that the electrical system of the entire plant is unified.
  • connection formed by the flexible multiple duct 10 is very simple, being achieved by inserting/withdrawing the plug 7 and the instant connector parts 8' and 9'.
  • a suitable extension consisting of a portion of duct 10 with the relative known connectors at its ends can be interposed to thus lengthen by even a considerable length the connection between the units 1 and 14 as required.
  • the object of removing the excess condensate from the cooled air is also achieved by means of the sprayer 20, with the further advantage of recovering the latent heat of condensation by its evaporation on the heat exchanger bank 22.
