Document Type and Number:
WIPO Patent Application WO/2024/045288
Kind Code:
A1
Abstract:
A phase-change cold-refrigeration process method and apparatus. Refrigeration is performed by using a multi-stage cascade phase-change cold-refrigeration cycle; liquid air is used as a final-stage refrigerant; and a refrigeration apparatus and method are used, in which no refrigeration compressor is used, and refrigerant vapor that is generated in a next-stage refrigeration cycle is condensed and liquefied under adiabatic expansion conditions by means of a refrigeration capacity of a lower temperature that is provided in a previous-stage refrigeration cycle, such that the technical effect of producing a low-temperature refrigeration capacity and liquid air in a high-power energy-saving and power-saving manner is achieved.
