More particularly referring now to the draw reduced pressure by vacuum pump‘ 8, will beIva porized in the form shown in Figure l; the Item-‘I perature of the compressed refrigerant ?uid in: 80 line‘ ID will be such that the water will be com pletely vaporized so that all. thatissues from pipe 28 will be a?ne‘spray.

The. operation. of the form of the invention‘ shown in Figure 1 and Figure 2 will be obvious 40 from the foregoing description. The motor ‘I is started and valve 26 is maintained closed until ings, a suitable casing or cabinet I houses a re i'rigerating coil 2 in proximity to which a blower , a vacuum or partial vacuum is applied in cham ber 23. The‘valve 26 is adjusted so that the ' fan 3, driven by an electric motor 4 or other water spray is“ that necessary for the desired 45 suitable means, is positioned. The blower is adapted to blow the air to be conditioned over cooling effect. The motor 4 blows air over the the refrigerating coil 2. The refrigerating coil refrigerating coil. The refrigerant ?uid is com 2 is provided with heat exchange ?ns 5 as is customary in the art. A pan 6 is positioned 50 underneath the refrigerating coil 2 to cool the moisture precipitated from the air due to its . being chilled’ belowfgthe dew point. Aisultable pressed and cooled in condenser H and expand ed in refrigerating coil 2. Moisture precipitated from the air being conditioned collects in pan 6 from which it is drained through line 30, whence it passes into a body of water 2| within tank 20. v In the form of the invention shown in Figures 4 s motor ‘I is corin‘eeted‘ to~_drive a compressor 8 and a ‘vacuum pum M9; 3 The refrigerant ?uid in and 5, an expansion refrigerating apparatus is the form of the invention shown in Figure 1 omitted and the entire cooling e?ect obtained by 2,133,343 2 the evaporation of the refrigerant liquid, which may be water or any other suitable liquid. If de an evaporation of the refrigerant ?uid, the effect of both evaporations being to reduce the tempera used to increase the cooling effect. In practice, however, the device may be made of sufficient size ture of the refrigerant ?uid which passes through the refrigerating coil 38. It will be observed that I have accomplished so that water may be used. ‘The motor ‘| is con nected to drive a circulating pump 3| and vacuum the objects of my invention. I have provided a cooling means for an air conditioning device sired, a liquid more volatile than water may be pump. 9. A tank 32, containing the refrigerant liquid 33 communicates with circulating pump 3|, 10 through line 34. The refrigerant liquid is intro duced through tank 32, through pipe 35, which is provided with a sealing means 33 so that the tank 32‘ may be sealed after liquid has been introduced thereinto. The pump 3| circulates liquid from tank 32 through line 31, through cooling coil 38, which is provided with a drip pan 6, as before. A blower 3, driven by a motor 4 for passing air to be conditioned over the refrigeratingcoil 38 is noted. The refrigerating coil 30 is likewise pro 20 vided with heat'exchange ?ns 5. The refriger which is efficient and compact. The spraying of ?nely divided water into the zone of reduced pres sure substantially necessitates the vaporization of 10 same. Thus I am enabled to furnish the latent heat of vaporization, water being vaporized from the refrigerant ?uid, then cooled. In theform of the invention shown in Figures 4 and 5, I obtain an added cooling effect by evaporation of a por the necessity of using a compressor. This has ant ?uid, after passing through the refrigerating the added advantage of giving a quiet device, free from noise and, at the same time, to reduce the coil 38, passes through line 39, through heat ex changer 40, vsimilar to condenser ||. The casing expense of the installation in that a small pump and an ejector are substituted for a. compressor 23 is constructed as before and provided with a and achieve substantially the same result in a 25 spray head 24 having a line 25 communicating cheaper, quieter, and more expeditious manner. This is of great importance further when a port able device is made, especially those devices de signed for conditioning living spaces in the home and in the office where noise is extremely objec with a tank 20, provided with water 2|- Line 25 is ?tted with a control valve 26. The interior of casing 23 communicates with vacuum pump 9 through line 21. The discharge from the vacuum pump S‘is through line 28 which terminates in an ejector 4|. One leg 42 of the ejector 4| communi cates with the interior of the tank 32. The re frigerant ?uid, after being cooled in heat ex changer 40, passes through line 43 into spray head 35 44, whence it is sprayed as shown in Figure 4. 15 tion of the ?uid, thus enabling the dispensation of the‘ compression expansion, refrigerating cycle. 'This enables me to eliminate valves and to avoid tionable and space is at a premium. It will be understood that certain features and sub-combinations are of utility and may be em ployedwithout reference to other features and sub-combinations. This is contemplated by and is within the scope of my claim. It is further obvious that various changes may be made in de The ejector will reduce the pressure existing with in tank 32, the vapors passing from ejector 4|, “ tails within the scope of my claim without de through line 45 to a point outside the space being parting from the spirit of my invention. It is, conditioned. 40 ' In operation, the motor in the form of the in vention shown in Figures 4 and 5 drives the cir-. culating pump 3| and the vacuum pump 9. The vacuum pump 8 pulls a vacuum win the interior therefore, to be understood that my invention is not to be limited to the speci?c details shown and 40 described. \ Having thus described my invention,‘ what I claim is: - of the casing 23 so that the .water from tank 2| ‘An air conditioning device including in combi is pulled and the enlarged space maintained at nation, a housing, heat exchange means posi tioned within said housing, means for maintain reduced pressure. The water is thus vaporized, the latent heat of vaporization being taken from the refrigerant ?uid circulating through heat ex changer 40. The refrigerant ?uid being sprayed 50 through the ?ne holes in pipe 44 also passes throug an area maintained at reduced pressure so that there is a partial evaporation of the re frigerant ?uid. The vapors of the refrigerant ?uid and the vapors of the water from the inte 55 rior of casing 23 'pass outside of air space being conditioned, through pipe 45. It will be seen that a double cooling eifect is achieved. We have an evaporation of water and 45 ing the housing under sub-atmospheric pressure, means for supplying liquid to said housing, a tank, a refrigerating coil, means for circulating a re frigerating medium from said tank, through said 50 refrigerating coil and back to said tank through said heat exchange means, a spray for spraying the circulating refrigerating medium back into said tank, means for maintaining said tank under sub-atmospheric pressure, means for passing air 55 to be conditioned over said refrigerating coil.
