摘要： A refrigeration apparatus has a refrigerant. The refrigerant is a non-azeotropic refrigerant mixture containing 50% by weight or more and 80% by weight or less of a high-boiling point refrigerant, 10% by weight or more and less than 50% by weight of a medium-boiling point refrigerant having a boiling point lower than that of the high-boiling point refrigerant, and 20% by weight or less of a low-boiling point refrigerant having a boiling point lower than that of the medium-boiling point refrigerant. The content of the high-boiling point refrigerant is larger than that of the medium-boiling point refrigerant, and the content of the medium-boiling point refrigerant is larger than that of the low-boiling point refrigerant. Piping through which the refrigerant derived from the compressor and flowing into the condenser passes includes a countercurrent flow configurator in which the refrigerant flowing through the piping is countercurrent to the cooling air.

摘要： An apparatus includes a captured carbon dioxide input. The captured carbon dioxide input is coupled to receive captured carbon dioxide from a direct air capture system. The apparatus uses the captured carbon dioxide as a low global warming refrigerant to provide cooling functionality in automotive, commercial, and industrial applications, or other operations involving low global warming refrigerants. In various embodiments, the apparatus is a refrigeration apparatus or a heat pump apparatus. Low global warming carbon dioxide refrigerant is natural, non-toxic, non-flammable, and abundant when obtained from a direct air capture system. Moreover, carbon dioxide refrigerant has a high heat transfer coefficient and has a global warming potential (GWP) of one. Carbon dioxide refrigerant is a more sustainable and efficient coolant option than common refrigerants, such as R22, R152, R404a, and R1234yf refrigerants.

摘要： A refrigerant cycle system includes: a first refrigerant circuit that includes a first heat exchanger, a first compressor, and a first cascade heat exchanger and that is configured as a first vapor compression refrigeration cycle; a second refrigerant circuit that includes the first cascade heat exchanger, a second compressor, and a second heat exchanger and that is configured as a second vapor compression refrigeration cycle; a first unit that accommodates the first heat exchanger and the first compressor; a second unit that accommodates the first cascade heat exchanger and the second compressor; and a third unit that accommodates the second heat exchanger. The first unit, the second unit, and the third unit are disposed apart from each other. The first cascade heat exchanger performs heat exchange between a first refrigerant that flows through the first refrigerant circuit and a second refrigerant that flows through the second refrigerant circuit.

摘要： An environmental control system for conditioning a cabin of a vehicle positioned in an enclosed air-evacuated environment includes a first inlet for a first medium, a second inlet for a second medium, and a thermodynamic device including a compressor and at least one turbine. The at least one turbine is fluidly coupled to and arranged downstream from the first and second inlet. A flow of the first medium and a first flow of the second medium are mixed to form a third medium at a first mixing point arranged downstream from the thermodynamic device relative to the flow of the first medium. A dehumidification system is fluidly coupled to the thermodynamic device and is arranged upstream from the at least one turbine. A regeneration heat exchanger is fluidly coupled to and is downstream from the compressor. Heat is removed from the first medium at the regeneration heat exchanger.

摘要： A refrigeration unit with dynamic air cooling is described. It includes a centrifugal compressor with an electric drive, whose outlet is connected to a working element, whose outlet is connected to the inlet of a turbine. The turbine is connected to an electrical energy generator, where the outlet of the turbine is directed towards a wall-pipe heat exchanger. The heat exchanger is connected to a pump. Between the centrifugal compressor and the working element there is a pipe-wall exchanger of the air-air type, to which a fan is connected. The working element of the unit has a cylindrical hollow profile comprising helical recesses with a substantially oval shape.

摘要： The disclosed embodiments relate to a system that provides a polymer heat exchanger with internal microscale flow passages. The system includes a set of plates comprised of a polymer that includes internal microscale flow passages, which are configured to carry a liquid. The set of plates is organized into a stack, wherein consecutive plates in the stack are separated by fins to form intervening air passages. The system includes a liquid flow pathway, which flows from a liquid inlet, through the internal microscale flow passages in the stack of plates, to a liquid outlet. It also includes an airflow pathway, which flows from an airflow inlet, through the intervening air passages between the consecutive plates in the stack of plates, to an airflow outlet. The liquid flow pathway flows in a direction opposite to a direction of the airflow pathway to provide a counterflow design that optimizes heat transfer between the liquid flow pathway and the airflow pathway.

摘要： A system includes a pressure exchanger (PX) to receive a first fluid at a first pressure, second fluid at a second pressure, and exchange pressure between the first fluid and the second fluid. The first fluid is to exit the PX at a third pressure and the second fluid is to exit the PX at a fourth pressure. A first condenser is to receive the first fluid from a compressor and provide thermal energy from the first fluid to a first environment. A second condenser is to receive the second fluid from the PX and provide thermal energy from the second fluid to a second environment. A heat exchanger is to receive the first fluid from the first condenser and the second fluid from the second condenser, provide thermal energy from the first fluid to the second fluid, and provide the first fluid to the PX.

摘要： In order to provide climate control system for heating or cooling a space, in particular a vehicle interior, having a compressor for conveying a refrigerant, which can efficiently use the refrigerant CO2 for heat pump applications as well, it is proposed to arrange a high-pressure chiller for cooling the refrigerant downstream of the compressor and a low-pressure chiller for heating the refrigerant upstream of the compressor, wherein a refrigerant exiting from the high-pressure chiller can be supplied to a motive mass inlet of a first ejector and a refrigerant exiting from the low-pressure chiller can be supplied to a suction mass inlet of the first ejector, and wherein an outlet of the first ejector is connected directly or indirectly to a liquid separator.
