摘要： A modified two-phase refrigeration cycle compresses a working fluid, condenses the working fluid into a saturated or supercooled liquid, expands the saturated or supercooled liquid into a two-phase fluid, and evaporates the two-phase working fluid. The modified two-phase refrigeration cycle reduces irreversibilities imposed by conventional refrigeration cycles and extracts energy from the working fluid during the expansion process. For instance, a system that employs the modified two-phase refrigeration cycle includes a two-phase expander to reduce irreversibilities during an expansion process and extract energy. In some instances, the system includes a two-phase compressor to compress two-phase fluids for varying loads and environmental conditions of the system.

摘要： Disclosed illustrative embodiments include systems and methods for power peaking with energy storage. In an illustrative, non-limiting embodiment, a power plant includes a thermodynamic piping circuit having a working fluid contained therein, and the working fluid has a flow direction and a flow rate. Power plant components are interposed in the thermodynamic piping circuit. The power plant components include a compressor system, a recuperator system, a heat source, a turbine system, a heat rejection system, and a thermal energy storage system. A valving system is operable to selectively couple the heat rejection system, the thermal energy storage system, and the compressor system in thermohydraulic communication with the working fluid maintaining the flow direction and the flow rate to implement a thermodynamic cycle chosen from a Brayton cycle, a combination Brayton cycle/refrigeration cycle, and a Rankine cycle.

摘要： This invention is about a cascade cold dynamic cycle refrigeration apparatus, which makes up cold energy with cryogenic liquid refrigerant by boosting with a dual-stage liquid circulating pump, 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 vapor compression refrigeration apparatus, so its maintenance and operation cost can be substantially reduced, with a apparatus of the same refrigerating capacity, it can save energy by more than 30% as compared with traditional ones, as compared with traditional refrigerating circulation technology, it can adopt enhanced cold transfer elements more conveniently, with more compact refrigerating equipment and higher refrigerating efficiency.

摘要： To provide a refrigerating cycle apparatus capable of improving cooling ability by water spray to perform an efficient operation while suppressing decrease in collected power by an expander. The refrigerating cycle apparatus includes: a first compressor that compresses the refrigerant; an expander that decompresses and expands the refrigerant to collect power for expansion; a second compressor that is driven by the power collected by the expander to further compresses the refrigerant compressed by the first compressor to transmit it to a main radiator; a heat exchanger having an intercooler that cools the refrigerant compressed by the first compressor and a main radiator that cools the refrigerant compressed by the second heat exchanger to transmit it to the expander; indoor heat exchangers that heat the refrigerant decompressed by the expander; and a water spray apparatus that sprays water onto the outer surface of the intercooler and the main radiator. The water spray apparatus sprays water such that the water spray amount per heat transfer area of the intercooler becomes larger than that of the main radiator.
