2 Claims.
This invention relates generally air conditioning apparatus and more particularly to an improved self-contained air conditioning unit.
employing a compressor-condenser-evaporator 5 circuit constructed and arranged in s h a manner as, to eil'ectively permit cooli g of. a condenser by outside air while at the same time maintaining a pleasing appearance and compact arrangement of the unit together with a simple and efiective arrangement for circulating room air over the evaporator.
, Various arrangements have heretofore been suggested in an attempt to provide a compact self-contained aircon'ditioning unit but the same have been deficient in many respects. Certain of these prior arrangements have utilized watercooled condensers which require expensive pipe installations and other inconveniences, whereas my improved unit employs an air-cooled condenser so arranged with the other elements that minimum floor space is required although various' features of my unit are equally" applicable to water-cooled condenser units.
It is one object of my invention to provide an improved self-contained substantially portable unit so arranged in cooperation with a window or other suitable opening in a room wall that outside-air may be efiectively circulated over the condenser to cool the same, and room air may be eflectively circulated over the evaporator, the compressor mechanism being so related to the condenser and evaporator that minimum floor space is required while at the same time highly emcient and simple air flow passages are obtained. In one specific aspect of the invention I provide a vertical unit with an air-cooled conthe unit may be conveniently placed either against a wall, or in a corner of a room, adjacent a window through which outside air is conducted over the condenser, the evaporator being disposed so that room air maybe effectively circulated thereo'ver in a simple manner without structural or functional interference from the condenser equipment, this being specifically accomplished by having a fan on one side of the evaporator so as to circulate room air directly transversely of the unit whereby the air enters one side of the unit and discharges from another side thereof in substantially horizontal directions.
A further specific aspect of the invention includes .a motor-compressor unit disposed in a lowermost compartment in vertical alignment with condenser and evaporator compartments,
thereby providing a ver tical unit which requires relatively small floor space and yet permits the condenser to be disposed at a very desirable location for simple and eflective communication with the outside atmosphere such as through either the top or intermediate portion of a window while at the same time allowing an efiicient location of the evaporator so as to to insure circulation of the cooled and dehumidified room air at the most effective elevation.
Other objects and advantageswill be more apparent to those skilled in the art from the following description of the accompanying drawings in which: i
Fig. i is a perspective of my improved unit lo cated against the wall between two windows whereby outside air is admitted through one window and discharged through the other;
Fig, 2 is a-perspective of the modified form of unit placed in a corner of the room adjacent one window which functions to admit and discharge :condenser cooling air; v
Fig. 3 is a vertical section taken substantially on the line 33 of Fig. i;
Fig. 4 is a plan section through the top of Fig. 2;
Fig. 5 is a plan section of the Fig. 1 form of unit placed in a corner with awindow in each wall whereby outside air may be eflectively circulated through one window and over the condenser and thence to the outside through the other window. 7
In the particular embodiments of the invention which are disclosed herein merely for the purpose of illustrating certain specific forms among possible others that theinvention might take, I have shown in Fig. 1 a vertical unit generally indicated at .l placed against a room wall and preferably between two windows [and 3. As shown in Fig. 3, the unit has three vertically aligned compartments containing a motor-compressor unit 30, an evaporator ii and condenser E. The motor-compressor unit may be of any suitable type but is herein shown preferably as of the vertical axis, hermetically sealed piston and cylinder type suitably supported on a base 6. Any suitable framework generally indicated at! may be secured on base 6' to support the con denser and evaporator and air circulating means therefor. The compartments are preferably separated by partitions ii and 9 and formed of sheet metal or wood as may be desired. The evaporator and condenser are preferably disposed to one side of their compartments, thereby providing fancompartments generally indicated at I0 Outside cooling air for the condenser is supplied from the top of window 3 through a window inlet duct l6 preferably but not necessarily of triangular shape in plan view as shown in Fig. 1. A filter i! may be disposed within this duct. The infiowing cooling air'is then circulated by fan l3 over condenser 5 and thence through an outlet window duct l8 communicating with the outside air through the upper part of window 2. 'The condenser 5 is preferably set back slightly from the left side of the unit to provide -a vertical air passage from the lower portion of the condenser to the relatively narrow duct l8.
A filter I9 may be interposed between the inlet and fan I! to filter the circulated room air. Also to take care of the condensate dripping from evaporator 4, well-known moisture eliminators may be placed on the discharge side of the evaporator. If the evaporator has vertical fins, the condensate may drip downwardly to accumulate in the bottom of the evaporator compartment, thereby to be pumped or otherwise circulated up over the condenser 5 to assist in cooling the same, or the condensate may be accumulated and periodically drained. If transverse fins are used, then the evaporator may be slightly inclined rearwardly so that condensate will flow rearwardly against the direction of air flow thereover, this condensate dripping down along the back of. the evaporotor to accumulatein the bottom of the evaporator compartment. cally shown as having-transverse fins with vertical coil pipes and is shown slightly inclined as above mentioned. An additional advantage of this slightly inclined evaporator is that the cooled room air is discharged into the room in an initial upward direction.
From the foregoing disclosures, it is seen that an extremely compact unit is provided in so far as requiring minimum floor space and at the same time the condenser is so disposed that it may efi'ectively cooperate with the window openings to permit outside air to be efliciently circulated over the condenser and discharged to the outside. It is also seen that the room air is circulated in a simple straight path from one side of the unit to the other and in such a direction as to cause circulation of room air in substantially a horizontal plane. The cabinet for the unit may be of any ornate or simple design such as may appeal to individual aesthetic tastes without in any way impairing the mechanical aspects or utility of the unit.
In the modification of Fig. 2, the unit has the same arrangement of. elements as that shown in Fig. 3 except a single window is utilized for the admission and discharge of outside air to cooi The evaporator is specifithe condenser. As shown in Fig. 4, the unit is disposed in a corner 2| of a room and is slightly spaced from one wall so as to permit room air to enter the inlet opening corresponding to opening ll of Fig. 3. The condenser fan, however, is shown as of the centrifugal type having a spiral casing 22 whose inlet opens directly into the fan chamber 23 and whose outlet communicates directly with one-half of the condenser. A vertical partition 24 extending throughout the vertical length of the condenser 25 permits outside air to be drawn inwardly through a window duct 26 and over one-half of the condenser and into the chamber 23, thence into the fan casing to be discharged over the other half of the condenser and out through another portion 21 of the window duct.
In the modification of Fig. 5, the unit of Fig. 3 is disposed in a corner and is slightly spaced from one wall thereof to permit room air to enter its inlet opening corresponding to ll of Fig. 3. The arrangement is otherwise identical to Fig. 3
except that the inlet duct I6 communicates with a window 3' while the outlet duct l8 communicates with a window 2'.
From the foregoing disclosures of these modifications it is seen that they have the same structural and functional advantages as above pointed out for the preferred form shown in Figs. 1 and 3 while other advantages inherent in the unit will be apparent to those skilled in the art.
It will of course be understood that various changes in details of construction and arrangement of parts may be made by those skilled in the art without departing from the spirit of the invention as set forth in the appended claims.
I claim:
