摘要： 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.

摘要： An air conditioning apparatus includes a refrigerant tank, a cryogenic liquid pump, a condensing evaporator, a compressor, a user system, a throttle valve, a first reversing valve, and a second reversing valve. It operates in two modes. In the first mode, the refrigerant in the refrigerant tank flows sequentially from the refrigerant tank, the cryogenic liquid pump, the condensing evaporator, the first reversing valve, the compressor, the second reversing valve, the user system, the first reversing valve, the second reversing valve, the condensing evaporator, the throttle valve, and back to the refrigerant tank. In the second mode, refrigerant in the refrigerant tank flows sequentially from the refrigerant tank, the cryogenic liquid pump, the condensing evaporator, the first reversing valve, the second reversing valve, the user system, the first reversing valve, the compressor, the second reversing valve, the condensing evaporator, the throttle valve, and back to the refrigerant tank.

摘要： 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.

摘要： This invention is about a natural gas isobaric liquefaction apparatus, which is based on the Rankine cycle system of similar thermal energy power circulation apparatus at cryogenic side, a cryogenic liquid pump is used to input power and the refrigerating media makes up cold to the natural gas liquefying apparatus, so as to realize the isobaric liquefaction of natural gas. The natural gas liquefying apparatus of this invention can save energy by over 30% as compared with the traditional advanced apparatus with the identical refrigerating capacity, therefore it constitutes a breakthrough to the traditional natural gas liquefaction technology, with substantial economic, social and environmental protection benefits.
