Изобретение касаетс холодильной техники и направлено на повышение экономичности холодильной установки, работающей с хладагентом , например гелием, в которой потребитель значительно удален от основной аппаратуры .The invention relates to refrigeration and is aimed at improving the efficiency of a refrigeration unit operating with a refrigerant, such as helium, in which the consumer is significantly removed from the main equipment.
Известны способы производства холода в криогенной установке, преимущественно гелиевой, путем сжати газообразного хладагента , охла51одени его, обратным потоком и разделени на два потока, один из которы после детандера используют дл компенсации необратимых потерь, а; другой - адиабатически расшир ют в область влажного пара,Methods are known for producing cold in a cryogenic plant, predominantly helium, by compressing the gaseous refrigerant, cooling it by reverse flow and dividing it into two streams, one of which, after the expander, is used to compensate for irreversible losses, and; the other is adiabatically expanding into the wet vapor region,
Описываемый способ отличаетс от из- вестных.тем, -то, адиабатическое расширение потока ведут до давлени ,необходимого дл преодолени возникающих/гидравлических сопротивлений, и этот поток перед потребителем дополнительно охлаждают до температуры , близкой к температуре кипени хладагента . Дополнительно поток охлаждают после адиабатического расширени дроссеп1ированием Части жидкого хладагента. Пары хладагента, отход щие от потребител , The described method differs from the known ones. Thus, the adiabatic expansion of the flow is carried out to the pressure necessary to overcome the arising / hydraulic resistances, and this flow in front of the consumer is further cooled to a temperature close to the boiling point of the refrigerant. In addition, the flow is cooled after adiabatic expansion by drossing a portion of the liquid refrigerant. Refrigerant fumes from the consumer
да, могут быть введены в пинию обратного потока на различных температурных уровн хYes, they can be put into return flow at various temperature levels.
На чертеже приведена схема установки, в которой может быть.осуществлен описываемый способ.The drawing shows a setup diagram in which the described method can be implemented.
Пары гели засасываютс компрессором 1 и нагнетаютс через теплообменник 2 к детандеру 3 и через теплообменник 4 и 5 к детандеру 6. Перед расширением в детандере 6 гелий охлаждаетс обратным потоком до температуры в конце расширени Близкой к температуре хладагента в объекте 7 потреблени холода, а давление -должно быть выше давлени обратного потока, например, на величину, необходимую дл преодолени гидравлического сопротивлени трубопровода 8.The helium vapors are sucked in by compressor 1 and injected through heat exchanger 2 to expander 3 and through heat exchanger 4 and 5 to expander 6. Before expansion in expander 6, helium is cooled back to the temperature at the end of expansion Close to the temperature of the refrigerant in the object 7, the cold consumption and pressure must be higher than the return flow pressure, for example, by the amount necessary to overcome the hydraulic resistance of the pipeline 8.
