摘要： A precooled vapor-liquid refrigeration cycle includes a basic vapor-liquid cycle (24) and an auxiliary regenerative vapor-liquid cycle (26) having a heat exchange relationship (18') between them. The basic cycle (24) includes a compressor (10) connected in series with a condenser (12), throttle device (14), and evaporator (16). The auxiliary cycle (26) includes a compressor (10'), condenser (12'), throttle device (14'), and a counterflow heat exchanger (18'), successively connected. The cycles each have condensers (12, 12') that are cooled by ambient air; the basic cycle is able to operate independently of the auxiliary cycle. To maximize the coefficient of performance, the basic cycle (24) operates with a small pressure differential between compressor discharge (G) and return (f). Efficiency of the basic cycle and the system COP are improved. The refrigerant leaving the condenser (12') in auxiliary cycle (26) after passing through the auxiliary throttle device (14'), flows through the heat exchanger (18') in the counterflow arrangement with the very same refrigerant stream.

摘要： A closed cycle refrigerating system for cryogenic temperatures using a single stage compressor (12) with a refrigerant comprising a gas mixture. The refrigerating system includes a heat exchanger (28) having a throttling orifice (34) which is arranged to provide refrigeration, and a single stage oil lubricated compressor (12) for compressing the refrigerant. The compressor is typically of the rolling piston type. The refrigerant is a mixture of at least one cryogenic gas having a normal boiling point below 120 degrees K and at least two other gases having normal boiling point temperatures below 300 degrees K different from each other and from said one gas. There is also included means (18) for cooling the compressed refrigerant and for circulating the cooled refrigerant to the heat exchanger and its throttling orifice and then back to the compressor. The system does not require any cascaded heat exchangers or intermediate phase separators.

摘要： Mixed refrigerants provide refrigeration at cryogenic temperatures with throttling cycles operating with a one-stage compressor. The refrigerants include noncondensable gases such as helium, neon, or hydrogen to increase the overall cooling capacity of a refrigeration system at the same refrigeration temperature which is attainable without such noncondensable gases. More refrigeration can be produced with existing systems at temperatures above the normal boiling point of nitrogen or argon by adding, for example, helium, than for refrigerant blends without helium. By increasing the return pressure value of the refrigeration cycle in relation to the molar percent of helium present in the refrigerant, a constant refrigeration temperature may be maintained which exhibits greater stability than prior systems operating at the same temperature without helium enrichment.
