8 Claims. (Cl. 62-440) The present invention relates to air conditioners and, particularly, to room-air conditioning units of the type which are equipped with rei'rigerating means. More specifically, the invention has to do with the disposal of water which accumulates, in such units, as a result of condensation of moisture removed from the treated air.
In equipment of the general kind above mentioned, the air which is intended for discharge into the room, is passed in heat exchange relationship with the cooling coils of an evaporator. In this manner, the coils cool the air and remove entrained moisture which condenses and collects on the surface of the coils. Attempts have been made to utilize the condensate as a cooling medium for-the condenser which is conveniently mounted for communication with the outside, through a window or like opening. For example, structures have been proposed for the purpose of dispersing the condensate in the ambient air and causing the moisture laden air to flow in heat exchange relationship with the condenser. Thus, some condensate is re-evaporated and produces a cooling effect on the condenser. Structures of this sort, however, have the disadvantage that the amount of water actually brought in heat exchange relationship with the condenser is minute as compared to the amount of water which falls back into the unit. Therefore, such structures not only fail to take full advantages of the condensate available to cool the condenser but, lack the ability to dispose of the condensate at a rate sufllciently rapid to insure that no overflowing will occur. In an effort to remedy these conditions, it has been suggested to employ a power driven pump adapted to spray condensate directly over the condenser. However, the provision of a pump is undesirable, because of the added costs of production, operation and up-keep.
It is, therefore, the primary object of this invention to provide an arrangement which eliminates the use of a power driven pump and yet is capable of making full use of the available condensate to cool the condenser efl'lciently, while disposing of such condensate.
It is also an object of the invention to provide an arrangement of the kind above specifled, which requires but a few simple parts adapted for convenient and ready association with existing parts of the air conditioning unit. Notably, the invention results in an arrangement which is economically produced and inexpensively not affect costs of operation and up-keep, and which is most reliable and eiiiective in preventing water overflow.
Another and more specific object of the invention resides in the provision of an arrangement whereby the condensate, which normally accumulates in a sump below the condenser, is transferred from such sump and is conveniently gathered above the condenser. This feature of the invention makes it possible to accumulate condensate at a location where it can be best utilized to cool the condenser, because the condensate is then able to drip over and in direct heat exchange relationship with the condenser. In this'manner, adequate and rapid vaporization of the condensate is assured and cooling of the condenser-in a most positive and efficient way is attained.
These and other objects, and the manner in which they are obtained, will appear from the following description based on the accompanying drawings wherein the invention is shown as applied to an air conditioning unit of the type adapted to be mounted on a window sill of an enclosure.
It is to be understood, however, that the invention, in its broadest aspect, is not limited to that particular application but may be used in any kind of air conditioner in which removal and full utilization of condensate for cooling the condenser is a problem.
In the drawings:
Figure l is a plan view, partly'in section, illustrating a preferred embodiment of the invention;
Figure 2 is a vertical sectional view taken substantially on line 2-2 of Figure 1;
Figure 3 is a sectional fragmentary view, on an enlarged scale, looking in the general direction of arrows 3-3 of Figure 2;
Figure 4 is an enlarged fragmentary view of a portion of the apparatus shown in Figure 2; and,
Figure 5 is a view similar to Figure 4, but illustrates a slightly modified form of the invention.
With reference to the drawings, the apparatus as shown particularly in Figures 1 and 2, includes a housin Ill which, in accordance with the practice now well known, is adapted to extend horizontally through a space between the sill and partly opened sash of a window. By mounting the housing ID in this manner, one end portion i i of said housing projects into the room, and the other end portion l2 of said housincorporated in air conditioning units, which does mg projects outside the room. A partition wall conduit 22.

ment I5, the condenser l8 being disposed adjacent an outside-air outlet 20 (Figure 2) which is provided at the rear of the housing. As particularly shown in Figure 1, the motor-compressor is adapted to withdraw evaporated refrigerant from the evaporator through a suction line 2|, and is adapted to discharge compressed refrigerant vapor into the condenser through a From the condenser, liquified refrigerant flows to the evaporator through a liquid line 23 in which is interposed a suitable flow restrictor, such as an expansion valve 24.
-The housing also encloses a motor 25 which is conveniently arranged in the rear compartment l5 and is adapted to drive fans 26 and 21. One fan 26 is located withinthe front compartment l4 and is disposed in cooperative relation with a shield or baille 28, so that air drawn through room-air inlets 29 flows in heat exchange relationship with the evaporator l6, as indicated by arrows A in Figure 1. The other fan 21 is located within the rear compartment l5 and is disposed in cooperative relationship with a shield or baille 30 (Figure 2), so that air drawn into said compartment through outside-air inlets 3| flows in heat exchange relationship with the condenser l8 asindicated by arrows B in Figure 1.
A damper 32 which is associated with an opening 33 in partition wall I3, provides for the admission of controlled amounts of outside air into the conditioning compartment M, as represented by arrows C in Figure 1. Suitable filters 38 are provided to purify the air passing into compartment M'through said inlets 29 and opening 33. This air is cooled and dehumidified as it passes in heat exchange relationship with the evaporator.
Condensate, which forms on evaporator I8, is collected in the usual sump or pan 35 which is conveniently disposed beneath said evaporator. A drain pipe 36 conveys condensate from sump or pan 35 to a second sump or pan 3! (Figures 2 and 3) which is conveniently located beneath the condenser. A rotatable wheel-like member 38 is mounted ahead of the condenser and is disposed to extend into the second pan 31, as can be clearly seen in Figures 2 and 3. This wheel-like member is suitably associated with the condenser fan 21. It may form a part of the fan or, as shown particularly in Figure 2, it may be connected to an extension 39 of the fan motor shaft, for rotation therewith. With such an arrangement, it will be understood that, as the water rises in pan 31, it comesin contact with the rotating wheel-like member which then picks up and throws water particles tangentially.
It is pointed out that the structure so far described is similar, in generality, to structures which have been previously used. It is, therefore, to be understood that such general structure forms no part of the invention except in so far as it relates to and affects the construction and operation of the characteristic features of 4 this invention, which features will now be described.
In accordance with the present invention, means are provided to intercept water which is thrown by the wheel-like member; to entrap the water at a level above the condenser; and, finally, to discharge drops of the collected water over and in direct heat exchange relationship with the condenser.
Basically, such means comprise a pan-andbafile structure which is adapted to be suitably mounted above the condenser. This structure, as shown in the drawings, includes a pan 40 disposed adjacent the top of condenser I9. The bottom of this pan is provided with perforations M and with an elongated slot 42. The perforations are located over the condenser and are distributed to extend substantially along the entire length of the condenser top (see Figure 1). The slot is disposed in general alignment with the peripheral edge of wheel-like member 38 (see Figures 2, 3 and 4). As is more clearly shown in Figure 4, the slot is conveniently formed in a reentrant portion 43 of the bottom of pan 40 so as to provide upstanding ridges 44 which serve to prevent water collected in the pan from overflowing through said slot.
Baille means in the form of a cover 35, is arranged over the pan 40 to insure that water which is thrown by member 38, will be intercepted and entrapped in pan lll. For that purpose the part of the cover which lies over the slot 52, is advantageously offset to provide an inverted V-shaped portion 46, the apex 41 of which is disposed substantially in line with wheellike member 38. The sides 48 of portion 88. are adapted to extend beyond the ridges (iii provided by the reentrant portion of the, pan $0. Because of this construction, water which is thrown upwardly by wheel-like member 38, strikes portion 46 and is deflected and guided into pan to by sides 88 of said portion. From the pan, water passes through perforations 4i and, as hereinbefore mentioned, is discharged over and in direct heat exchange relationship with 'the condenser.
A modified construction of the arrangement above described is shown in Figure 5. According to this modified construction, a pan 68a mounted above condenser 18, extends only a short distance over the latter, as shown at 49, and one of the sides 68a of the inverted V-shaped portion 55a of cover 45a, is projected to contact said condenser beyond the pan, as shown at 50. With' a construction of this kind, a certain amount of the water which is thrown against portion 46a, drains along the inclined surface of the mentioned side of said portion and drips directly onto the condenser. The remainder of the water which strikes the cover portion 88a, drips and accumulates in pan 40a and is discharged therefrom through perforations 4 la, in the manner previously described.
It is to be noted that the size of perforations 4| is such that water does not flow freely therethrough but is discharged in drops from the pan 49. It is also to be noted that a portion of pan I8 is in direct contact with the top of the con denser. In this manner, a considerable amount of heat in the condenser is readily taken up by the water in pan 40. As a result, water dripping from the pan is heated, so that it is well conditioned to evaporate rapidly. This is especially true of the preferred embodiment (Figures 1-4) in which a substantial portion of the pan extends over and contacts the entire top surface of the condenser.
From the foregoing, it will be appreciated that an arrangement constructed in accordance with this invention/can be readily manufactured and easily installed in air conditioning units. Use of the arrangement is especially desirable because no complicated expensive mechanism is required to provide for effective cooling of the condenser while disposing of accumulated conlarity, it is to be understood that this has been L done by way of example only. Various changes in the details of construction and in the combination and association of parts may be resorted to without departing from the spirit of the invention, which is subject only to such limitations as are imposed by the prior art or are specifically called for in the appended claims.
