Definitions

  • a window type air conditioner in which moisture derived from the evaporator is conveyed to a condensercontaining chamber for disposal therein, said chamber including a wall having an inlet ring which confronts a condenser fan and around the interior surface of which ring moisture circulates during operation of the apparatus.
  • a retaining wall impedes flow of moisture out of the inlet ring in a direction upstream of the condenser fan, and an aspirator baffie means confronts the fan and projects radially inwardly of the inlet ring to establish a reduced pressure zone on the fan side of the baffie means.
  • Moisture circulating in the inlet ring flows to the outer edge of said baffie means and thence across the baffie means to an inner edge thereof from which it is discharged and entrained in the condenser cooling air stream.
  • the general objective of my invention is to eliminate the above mentioned problemsby insuring complete entrainment of all of the moisturein the condenser cooling airstream thus enabling the air conditioner to run with a'drier sump.
  • a slinger ring as a primary means, for entraining moisture, in combination with an aspirator baffle which is disposed to serve as a water elevating pump which takes any excess moisture which may be circulating within the fan inlet ring and insures entrainment thereofin the condenser air stream.
  • This baffle structure is carried as an extension of the inlet ring and projects radially inwardly thereof toward theaxis of the fan.
  • the baffle has two portions, one of which comprises means for lowering the pressure and raising the moisture to a free edge of said one portion.
  • the other portion also performs this function to some extent, but is particularly useful in preventing splashing of the particles of moisture outwardly from the fan.
  • the apparatus is featured by being simpler, cheaper, and more effective than moisture eliminating apparatus previously used in this art.
  • the aspirator baffle of this invention forms a part of the shroud inlet ring and directly confronts the fan. Maintaining the baffle as close as possible to the fan blading has been found to achieve the greatest possible pressure reduction and thence to maximize the pumping and removal of excess moisture. Thus it eliminates the moisture before it can escape from the inlet ring and arrive upstream of the fan.
  • FIG. 3 is a side view illustrating certain details of the fan shroud and air inlet ring.
  • FIG. 1 there is diagrammatically illustrated at 10 an air conditioner of generally known type which includes an evaporator 11, a condenser l2, and evaporator and condenser fans 13 and 14, respectively, arranged to be driven by an electric motor 15 through shafting shown at 16.
  • evaporator 11 a condenser l2
  • evaporator and condenser fans 13 and 14 respectively, arranged to be driven by an electric motor 15 through shafting shown at 16.
  • Mean which provides a sump under evaporator 11, the sump being shown in simplified form at 17 in FIG. 1.
  • Moisture derived from the evaporator is collected in the sump, from whence it flows through a hose or pipe 18 into the condenser chamber 19 for disposal therein.
  • a sump would also underlie the condenser 12 and its fan 14, and that the moisture would be collected in said sump for entrainment in the stream of condenser cooling air.
  • the inner side of the condensenthat is the side which is presented toward the evaporator compartment 20, is covered by shroud structure 21 which forms a plenum and which is provided with an aperture within which is disposed the condenser cooling fan 14.
  • the aperture is de- I fined by an air inlet ring 22 which protects-the fan and promotes flow of outdoor cooling air over the condenser. This air can be inletted to the machine in any suitable. manner not shown.
  • a slinger ring 23 which is of known type, has angular cross section (FIG. 3), and surrounds the periphery of FIG. 2 is a perspective view, on a larger scale, showing the condenser, its cooling fan, and the moisture enthe fan blading and is attached thereto through the agency of short extensions 24 which are formed integrally with the blades (see upper portion FIG. 2)
  • This slinger ring dips within the moisture collectedbeneath the condenser and fan, throwing the water outwardly into position in which it is entrained in the condenser cooling air derived from fan 14.
  • each baffle portion has an upper edge which terminates in the said apex and from which edge is discharged moisture in the manner now to be described. Due to the impedance which the baffle structure presents in the air flow path, a zone of lower pressure is formed behind each baffle portion.
  • baffle structure in its broader, aspect is not limited to baffle structure of any particular shape, it is preferred that this structure comprise the two generally triangular portions described. Also, in order to-take advantage of the natural tendency of the water to circulate downwardly around the inlet ring 22 in the direction of rotation of the fan,-it is preferred that the baffle structure be located in the lower righthand quadrant of the eye of the blower, ash is seen in. FIG. 2. Thatis, the baffle structure is located in that lower quadrant in which thewater is first caused to flowupwardly as it circulates within the inlet ring. This results in maximum benefit from the zone of low pressure developed behind the baffle and immediately ahead of the fan blade.
  • baffle means confronting the fan and projecting radially inwardly of the ring and es-' tablishing a reduced pressure zone on the fan side of said baffle means, the reduced pressure causing moisture circulating in said ring to flow to an outer edge of saidbaffle means and thence across the baffle means for discharge therefrom and entrainment in the condenser cooling air stream.
  • baffle means is carried bythe inlet ring and projects radially inwardly of the ring as an extension thereof.
  • baffle means is carried by the inlet ring and comprises a pair of upper and lower contiguous portions, projecting radially inwardly of the ring as exten- 5.
  • said baffle means lies in that lower quadrant of said ring in which the water is caused to circulate upward.
  • the improvements which comprise: primary means for entraining water in the air which cools the condenser, said primary means comprising a slinger ring which is carried by and surrounds the periphery of the fan, moisture entrained by said slinger ring having a'tendency to reach the interior surface of said inlet ring around the interior surface of which it circulates under the influence of said fan; and secondary moisture entrainment means comprising baffle structure confronting the fan and
