3 Claims.
My invention relates to air conditioning apparatus and has for an object to provide improved apparatus of this kind.
A particular object is to provide a simplified construction of air-cooled unitair conditigner that may be manufactured at reduced cos Still further objects oi my invention are to facilitate the removal of moisture condensed from the air, and to conserve floor space in an air conditioning device fora room or enclosure.
These and other objects are effected by my invention as will be apparent from the following description and claims taken in connection with the accompanying drawings, in which:
Fig. 1 is a vertical sectional view of my improved air conditioner attached to a conventional window opening:
Fig. 2 is a plan view of the apparatus shown in Fig. 1 with parts removed for cleamess; and Fig', 3 is a vertical sectional view of a second embodiment of my improved air conditioner.
Reference will now be had to Figs. 1 and 2 of the drawings wherein I have shown my novel air conditioning apparatus, comprising an air cooled unit air conditioner indicated generally at I0, disposed in the lower portion of a window Il and resting on the slll ii' thereof. The unit I formsa closure for the window opening upon the sash i2 being brought down to engage the top of the unit. .The window frame and sash provide a window in a wall i3 of a room or enclosure to be airv conditioned indicatedl at I4, the atmosphere exterior of the enclosure being indicated at i 5. The unit I0 is preferably mounted so that its center of gravity lies centrally of the sill il', and it is removably' secured in the window frame in any suitable manner. Lugs` or ears I0 fixed to the conditioner may be secured by suitable removable fastening devices to the window frame on the wall Il.
The unit air conditioner i0 includes a refrigerating system of any suitable type for cooling. the air in the-enclosure i4. I have shown a system of the compressor-condenser-expander type vhaving a heat absorbing element or evaporator I6 and a heat dissipating element or condenser II. A compressor mechanism, indicated at I8. withdraws refrigerant vapor from the evaporator I8 through a conduitl and compresses it to a relatively high pressure. The compressed vapor is delivered to the condenser i'i by means of a conduit 2 l, in which condenser the vapor is cooled and liquefied. 'Ihe condensed refrigerant ows from the condenser through a conduit 22 to any suitable expansion device 23, such as s conventional thermostatie expansion valve, iioat valve. or other expansion device, wherein the pressure of the refrigerant is depressed. Vaporizstion of the refrigerant at relatively low pressure in the evaporator i8 is effected whereby`hest is abstracted from the evaporator. This cycle of operation continues during periods of operation of the compressor il,
The compressor II may be of any suitable type, but I have preferred to show one of the hermetically sealed type. In this type, the motor, driven compressor (not shown) is enclosed and hermetically sealed within' a shell, all of which is indicated by the numeral Il.
The refrigerating system is enclosed by a nousing or casing 24 having a partition 24 for dividing the same into chambers 2l and 24, disposed adjacent the enclosure I4 and the exterior atmosphere il, respectively. In the present embodiment, the casing projects beyond the wall into the enclosure and into the exterior atmosphere, the chamber 25 being disposedwholly within the enclosure. 'I'he evaporator II is disposed wlthin the chamber 2l. A fan 28 is also provided therein for withdrawing air from the enclosure I4 through an inlet opening 21, for conveying the same over the surfaces of the evaporator I4 and for discharging the cooled air through a discharge opening 20 into the enclosure I4. In order that the casing 24 may t within windows of various widths, I provide an extensible closure member Il between one side of the casing 24 and the window frame. The closure member may be constructed in any manner known in the art.
The chamber 24 contains the compressor I8 and the condenser l1, the latter being disposed across an inlet opening 32 in the bottom of the Acasing 24. A fan 3i is provided in the chamber 2l for eilecting flow of outside air inwardly through the inlet opening 32 and over the condenser for cooling the same, through the chamber-zand outwardly through a discharge opening 33 inthe side wall of the casing. The compres? sor mechanism I8 is cooled by the air passing through the chamber 26, particularly by the eddy currents produced therein.
In order that fresh air in controlled quantities may be furnished to the enclosure i4, I provide a fresh air duct 34 which communicates at its outer end with the atmosphere exterior of the enclosureand at its inner end with the chamber 2l, preferably, on the upstream side of the evaporator I4. A damper 85.. actuated by a handle Il. controls the volume of fresh air conveyed by the duct 84 for mixture with the air withdrawn from the enclosure. As the inner end oi the duct I4 communicates ,with the suction side of the fan, air hows from the ex,-`
terior of the enclosure inwardly through the duct in quantities determined by the setting of the damper 85.
Water which may collect on the evaporator I8 due to the cooling of air below its dew point temperature. drops to a pan or collector 81. 'Ihis water must be removed and is, preferably, discharged to the outside atmosphere for vaporisation therein. Accordingly, I have provided a conduit 88 for draining the water collected by the pan 81 to the air stream conveyed by the blower II. The end 88 of the conduit 88 may be provided with one or more openings 4I through whichl the water is discharged for vaporization. Preferably, the openings 4I are so arranged that the water issuing therefrom is deposited upon the condenser structure Il for assistingin the cooling thereof; the latent heat of vaporization o! the water being abstracted from the condenser and the air passed thereover.
Reference will now be had to Fig. 3 wherein a second embodiment of my improved air conditioner is shown. In this embodiment, a casing structure 45 for housing the elements of the refrigerating system is mounted upon and supported by the window sill II'; said casing 45 including a downwardly extending portion 45 which is disposed within the enclosure I4. The portion 48 of the casing defines a chamber 4'I in which the compressor mechanism I8 is disposed.
A base 48 is arranged at the bottom of the casing portion 48 which base 48 rests upon the l iloor and is adjustable with respect to the casing portion 48 for various elevations of the window sill. 'I'his adjustment is provided preferably, by telescopically arranging the base 48 within the casing as shown at 48. After the proper adjustment is made these elements may be secured together in any suitable manner such as for example by screws 5 I The arrangement of the evaporator I6 and the condenser I`I within the chambers 25 and 25 of the upper portion of the casing 45 is similar to that' shown in Fig. 1. The principal difference between the two embodiments resides in the location of the compressor mechanism I8. By disposing the compressor mechanism I8 as shown' in Fig. 3, the length or distance that the casing 45 of the conditioner extends through the window II, may be reduced. In the second embodi- I4 may be eilected by the fan or blower 8|. An openingllmaybeprovidedinthebasenforthe4 of air from the enclosure I4 into the passage chamber" and a duct Il is employed for con ducting the air from the chamber 41 to the chamber I8, from which it is discharged to the outside atmosphere by the ian II. A damper Il is preferably disposed in the duct l'l for controlling the amount of air discharged from the room. The passage of air through the chamber 41 may be utilised for cooling the compressor Il. but it will be understood that the latter may be cooled by any other mutable means.
Except as recited heretofore. the operation of the unit conditioners of both embodiments is similar.
From the foregoing. it will be apparent that I have provided a novel air cooled device which may be disposed in a conventional wall opening for cooling the air in an enclosure or room, wherein the heat abstracting and the heat dissipating elements may be compactly arranged as a unit structure, so that a considerable saving in the space occupied by apparatus of this kind within the room is eilected. Furthermorathe various elements are assembled as a unit at the factory and are so arranged that, when the unit is installed in a window opening, it is unnecessary to provide the usual long tortuous ducts for conveying outside air for cooling the condenser. The water precipitated from the air being cooled may be readily removed by gravity by my improved device and, furthermore may be employed i'or assisting in cooling the condenser.
While I have shown my invention in several forms, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and I desire. therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.
What I claim is:
l. An air conditioner unit suitable for conditioning the air oi a room comprising two compartments, a refrigeration apparatus having a heat absorbing portion, a heat dissipating portion, and a motor-compressor, the heat absorbing portion being in one compartment, and the heat dissipating portion and the motor-compressor being in the other compartmentl said unit beingbadapted to be held in such position with ment, a portion of the weight of the unit condif tioner is carried by the base 48 so that the sill II is relieved of this portion of the total weight.
