Abstract
A cascade cold dynamic cycle refrigeration apparatus makes up cold energy with a cryogenic liquid refrigerant by boosting with a dual-stage liquid circulating pump. The temperature of the refrigerant is increased via the cold regenerator before it enters the cold consuming apparatus to provide cold and becomes a gaseous refrigerant. The gaseous refrigerant then flows through the expander to expand and generates work by reducing pressure and temperature. The gaseous refrigerant is condensed and returns to the refrigerant tank via the cold regenerator or/and a throttle valve.
