ABSTRACT:
Two heat exchangers are hooked up together in order to generate a flow of cold gas. A deep-frozen liquefied medium is evaporated in the first heat exchanger (1) by means of heat exchange with a heat transfer medium. The evaporated medium is re-cooled in the second heat exchanger. The deep-frozen liquefied cryogenic medium used for this purpose is likewise evaporated in this process. The two flows of gas thus generated are conveyed to a mixing site and then combined to form a flow of cold gas.
