Abstract: A high lever air conditioner in which a gas energy used as a principal refrigeratory (heating) cycle 8 form cycle consists of a J pipe of air energy heat pump, a J pipe of supercondensation and a heat pump of difference for energy conversion. Theory thermal energy conversion EER thereof can tend to .infin., is much greater than Carnot cycle. Actual air conditioner system which needs elements of consumed energy, such as a cycle pump, an energy control device, a fan, etc., has EER value of 20-35. Three difficult problems including high energy consumption, chlorofluorocarbons (CFC.sub.5) refrigerant which is contracted, and the lower air quality in conditioned room that is heavily restricted, the development of the present air conditioner may be simultaneously solved.

Abstract: The present invention relates to a method and apparatus for the generation of essentially spherical frozen droplets of a liquid biological or organic-comprising composition. The liquid composition if fed under positive pressure through a nozzle in a manner which provides a continuous stream of the liquid composition exiting the nozzle; the continuous stream travels through a gas or vapor for a distance sufficient to cause the continuous stream to break apart, forming droplets ranging in size from about 0.6 mm to about 5 mm; the liquid composition droplets are then contacted with a cryogenic liquid capable of freezing the droplets into a solid phase; the frozen droplets are concentrated into a portion of the contacting cryogenic liquid from which they are subsequently separated.

Abstract: Apparatus for providing an expendable refrigerant which is emitted from a snow horn at a low velocity thereby enabling snow agglomeration at a close proximity to the horn exit and accurately delivering a charge of snow with minimum vapor loss. The desired snow is produced by introduction of the relatively warm liquid refrigerant into an insulated compartment and in heat exchange relation with a tube therein having a plurality of length/diameter ratios. The liquid refrigerant is effective to warm the tube walls and results in a slight cooling of such liquid which is then passed to a subcooler and returned to the tube inlet for expansion in several stages therein to form the snow. The product snow is emitted from this horn at a relatively low velocity and may be accurately directed into cavities of such products as eviscerated fowl.
