REFRIGERATION SYSTEM WITH CARBON DIOXIDE INJECTOR

摘要

A system for producing refrigeration from a source of liquid carbon dioxide. The liquid carbon dioxide is injected through a nozzle into a primary stream within an elongate enclosure. The enclosure is mounted with its inlet end spaced about the nozzle to define an opening through which an annular stream of ambient gas is directed about the primary stream. The ambient gas turbulently intermixes with the injected coolant for subliming any solid carbon dioxide or snow so that the resulting stream exhausting from the enclosure is free of snow.
