Patent number: 9823000Abstract: This invention is about a cold dynamic cycle refrigeration apparatus, which makes up cold energy with cryogenic liquid refrigerant by liquid circulating pump boosting, after its temperature is increased via the cold regenerator, it flows through the expander to reduce pressure and temperature to provide the cold to the refrigeration apparatus, and then returns to the refrigerant tank via the cold regenerator, so as to form the cold dynamic cycle circuit of the refrigerant. This invention requires no circulation cooling water system as in a traditional steam compression refrigeration apparatus, so its maintenance and operation cost can be substantially reduced, with an apparatus of the same refrigerating capacity, it can save energy by more than 30% as compared with traditional ones, producing substantial economic, social and environmental protection benefits.Type: GrantFiled: January 24, 2014Date of Patent: November 21, 2017Assignee: NANJING RECLAIMER ENVIRONMENTAL TEKNIK CO., LTDInventor: Haibo Wang
