The herein disclosed method of cold generation provides for the compression of refrigerant and its subsequent cooling. Then, at least part of the refrigerant flow if expanded, accompanied by the generation of wave energy which is extracted from the expansion zone by way of converting it to energy of another kind. Provision is made of a plant for accomplishing the method, wherein a refrigerant expansion device 20 includes a gas-jet mechanowave converter 21 and a wave energy converter 22 in the wave relationship therewith.

Method of cold generation and a plant for accomplishing same

The herein disclosed method of cold generation provides for the compression of refrigerant and its subsequent cooling. Then, at least part of the refrigerant flow is expanded, accompanied by the generation of acoustic or another type of wave energy which is extracted from the expansion zone by way of converting it to energy of another kind. Provision is made of a plant for accomplishing the method, wherein a refrigerant expansion device 20 includes a gas-jet mechanowave converter 21 and a wave energy converter 22 in the wave relationship therewith.

A method of obtaining refrigeration at a cryogenic level comprising a gaseous fluid fed in the form of an incoming stream to sustain a refrigerative load. The incoming stream is stepwise cooled and expanded with liquefaction. The liquid fluid formed is used to sustain a refrigerative load, evaporating as a consequence, and the vapour constitutes a return stream which is adiabatically compressed so as to attain a temperature close to the temperature of the incoming stream before the liquefaction thereof.

Method of obtaining refrigeration at cryogenic level

A method of producing supercold temperature in cryogenic systems by compressing a gaseous fluid constituting an incoming stream followed by its stepwise cooling by a return stream of the fluid. The incoming stream is split into a main stream and a subsidiary stream which is used to compensate for the losses in the system on being expanded with the removal of energy. The main stream is expanded and liquefied in a liquefaction stage. At least a portion of the subsidiary stream, on being expanded with the removal of energy, is introduced into the liquefaction stage, liquefied therein and used to sustain a refrigerative load. After that, the liquid fluid formed is used to sustain the refrigerative load and is evaporated as a consequence. The vapor forms the return stream which is passed through the cooling stages and the liquefaction stage in the reverse direction. In realizing the method disclosed, the cooling of the incoming stream in the liquefaction stage is associated with energy losses which are by far smaller than ever before.
