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 enters the cold consuming apparatus to provide cold and becomes a gaseous refrigerant, then it flows through the expander to expand and make work by reducing pressure and temperature, and then returns to the refrigerant tank via the cold regenerator or/and throttle valve. 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.

The present invention is comprised of a heat supply circulation circuit: the liquid refrigerant from the refrigerant tank, after being boosted by the cryogenic liquid pump, enters the condensing evaporator, to transfer the cold to the backflow refrigerant at a higher temperature, after increasing pressure and temperature via the compressor, it is sent to the user system to supply heat, the refrigerant gas from the user system enters the condensing evaporator, and returns via the throttle valve to the refrigerant tank; and a cold supply circulation circuit: the liquid refrigerant from the refrigerant tank, after boosting by the cryogenic liquid pump, enters the condensing evaporator, to transfer the cold to the backflow refrigerant in the cold recovery channel, the refrigerant, after releasing the cold energy with increased temperature, flows to the user system to supply cold, the refrigerant gas from the user system returns via the compressor, condensing evaporator, and throttle valve to the refrigerant tank.
