Definitions
- ABSTRACT This invention relates to an air conditioner condenser section which includes a condenser and a low speed, double-exit centrifugal blower having a large diameter fan wheel.
- the fan wheel speed and velocity of the air passing through the condenser may be kept relatively low to provide a more quiet and efficient operation.
- Slanted water channel means are also provided to pump, by an aspiration effect, the water that has collected in the bottom pan of the air conditioner and housing to the blower fan wheel for atomization and dispersal.
- Air conditioning systems of conventional design utilize a blower arrangement that is necessary to move a required cooling air flow through the condenser.
- a draw-through air path is desirable for uniform air flow through the condenser.
- present centrifugal blowers are low in efficiency for this application while a propeller fan is very noisy.
- An air conditioner condenser section housing having end walls and a rear grill wall with an integral central air intake grill portion and side discharge portions,'a housing bottom pan which is disposed at a first elevation for collecting condensed water, a compressor, a condenser coil, a rotating centrifugal fan wheel having an inlet which is disposed at a second elevation within the housing, a fan scroll member having at least two outlets, and a condensate water disposal means.
- the fan scroll discharges air through the scroll outlets and in a direction towards the end walls of the housing where the air is turned to pass through the side discharge grill portions of the housing, while at the same time, air being discharged from one of the scroll outlets also cools the compressor.
- the condensate disposal means which consists primarily of a sloping channel extending between the first and second elevations is adapted to pump water from the housing bottom pan to the inlet of the rotating fan wheel by an aspiration effect for atomization and discharge with the air being pumped by the fan and turned to pass through the discharge grills. Air that is discharged at the scroll outlets is turned approximately 90 which will centrifuge any large water droplets against the side walls of the housing for eventual recollection and discharge, thereby preventing large droplets from being blown outside the housing.
- the aspiration effect is created within a portion of the sloping channel by a flow of air due to the air pressure differential that exists between ends of the channel, thereby providing an efficient condensate disposal system with no moving parts in combination with an air conditioning unit.
- FIG. 1 is a top view of an air conditioner condenser section employing the present invention
- FIG. 2 is a section taken along lines 2-2 of FIG. 1;
- FIG. 3 is a section taken along lines 3-3 of FIG. 2;
- FIG. 4 is an enlarged detail of the condensate water disposal arrangement of the present invention.
- an air conditioner evaporator section housing is shown generally at 2 and a condenser section housing at 3.
- Condenser section housing 3 includes end walls 4 and 5, a draw-through air intake grill portion 6, side discharge grill portions 7 and 8, and a housing bottom pan 10 (shown best in FIG. 2).
- the housing bottom pan 10 is disposed at a firstelevation to collect both condensed water from the air conditioner evaporator coil (not shown) and accumulated rain water from the outside of the housing.
- Enclosed within condenser section housing 3 are also a compressor 12, a condenser coil 14, and a low speed centrifugal blower l6.
- Centrifugal blower 16 includes both a large diameter rotating centrifugal fan wheel 17 disposed at a second elevation with respect to the first elevation of pan l0 and fan scroll member 18 having at least two outlet conduits for discharging air, as illustrated, in a direction towards the end walls 4 and 5 of housing 3 to be thereby turned to pass through side discharge grills 7 and 8 of housing 3 (which will be explairied in more detail hereinafter).
- a large diameter fan wheel 17 By employing a large diameter fan wheel 17, the wheel speed and air velocity may be kept relatively low, thus maintaining quiet blower operation.
- Condensate disposal arrangement 30 includes a hollow sloping channel portion 32 (a section of which is shown in FIG. 3) that extends from housing bottom pan 10 to the rotating fan wheel 17 and from the first to the second elevation. Sloping channel portion 32 may be attached in any well known manner to the blower inlet shroud 28, as illustrated. An inlet portion 34 of channel 32 is adapted to receive the water which has accumulated in bottom pan l0.
- Inlet portion 34 is disposed adjacent the first elevation and is aligned substantially parallel to the bottom pan 10 of housing 3.
- Channel 32 has a discharge end 35 terminating at the blower wheel inlet orifice 36 from which the collected water may be emptied into rotating fan wheel 17 to be subsequently atomized and discharged with the air being pumped by blower l6 and turned through the side discharge grills.
- a condensate drain tube 38 is also provided which carries water from the evaporator section to be thereby transported and emptied from drain discharge orifice 40 into the blower inlet opening 45 for eventual atomization and discharge.
- the height of the water receiving channel inlet portion 34 be greater than the static level of condensed water to be received therein, so as to always provide a free air flow path within channel 32 towards the discharge end 35.
- the high velocity air which has been generated above the collected water by the pressure differential in sloping channel 32, is capable of causing an aspiration effect, thereby providing means whereby collected water may be pumped along the inner surface of the sloping channel from the first to the second elevation (as diagrammatically illustrated). Without the provision for a free air path, an aspiration effect would not be possible, and the disposal means would not be effective for pumping water to the rotating fan wheel.
- the collected water can be lifted a vertical distance D of at least three inches because it is carried and aspirated up the slope of the channel by the high velocity air in discreet slugs or droplets 42 which are propogated in inlet portion 34.
- the pumping of the collected water into the rotating fan wheel for discharge can help to break up the water into fine droplets as it passes through the blower wheel.
- air is discharged from the blower outlet conduits towards the end walls 4 and 5 of housing 3 to be passed through side discharge grills 7 and 8. With the air being turned approximately 90 at the blower outlet conduit, as illustrated, only small droplets in the air will be able to pass through the side discharge grills 7 and 8, because any large droplets still remaining will be both centrifuged and separated out against side walls 4 and 5 to eventually drop back into pan 10 for re-collection and discharge. This feature insures that only small droplets will be discharged and that no large droplets will be blown outside.
- the compressor 12 is disposed at a position within housing 3 such that air being discharged from one of the blower outlet conduits not only centrifuges out large water droplets against the compressor and the housing side wall, but simultaneously passes over and cools the compressor.
- the water disposal means of the present invention may continuously pump water from the bottom pan to the blower fan wheel inlet to thereby greatly increase the maximum water disposal capacity of the system.
- An air conditioner condenser section housing having end walls and a rear grill wall with a central air intake grill portion and side discharge grill portions, a housing bottom pan, said bottom pan being disposed at a first elevation for collecting condensed water, a compressor within said housing, a condenser coil within said housing, a rotating centrifugal fan wheel having an inlet disposed at a second elevation, a fan scroll having at least two outlets for discharging air in a direction towards the end walls of the housing to be thereby turned to pass through the side discharge grill portions of said housing, and condensate water disposal means whereby water which has collected in said housing bottom pan may be delivered to said rotating fan wheel for atomization and discharge with the air pumped by said fan and turned through said discharge grills.
- said condensate disposal arrangement includes a sloping channel, said channel extending from said housing pan to the inlet of said rotating fan wheel and from said first to said second elevation.
