Title:
A REFRIGERATING METHOD AND THE CYCLE SYSTEM USING COOLING AMOUNT OF PHASE TRANSITION
Document Type and Number:
WIPO Patent Application WO/2001/014805
Kind Code:
A1
Abstract:
A refrigerating method and the cycle system using cooling amount of phase transition, the system consists of the first cycle, any of the intermediate cycles and the last cycle. The first cycle is the prior art, the other cycles are refrigerating cycles using cooling amount of phase transition, which make use of the cooling amount of the previous cycle and make the cooling medium of this cycle condense under adiabatic expansion. The first cycle provides original cooling amount, the last cycle provides the cooling amount to user, and any one of the intermediate cycles enlarges the cooling amount of the previous cycle. The temperature of generating cooling in various cycles increase in sequence from the first cycle to the last cycle. The heat generated by the first cycle is absorbed by the next cycle. There is no heat discharged to environment, the temperature of providing cooling is low, and the cooling efficiency is high.
