Abstract

The invention relates to the field of cryogenic engineering. The aim of the invention is to increase the economy when cooling with direct flow at supercritical pressure. The invention relates to refrigeration equipment, and more specifically to cryogenic gel installations. The purpose of the invention is to increase the economy with cooling with direct flow at supercritical pressure and long lines in the cooling facility. The drawing shows the ejector stage diagram. The ejector stage contains evaporator 1, subcooled itel 2, drost sel 3, lines 4 and 5 of direct and reverse flow, heat exchangers 6 and 7, cooling facility 8, ejector 9, the proposed installation works as follows: Gas pre-cooled cryogent direct flow with super-high lines in the cooling facility . The goal is achieved by the fact that in the ejector stage of a cryogenic installation containing an evaporator 1 and a fuse 2, the first zones of which are connected to the line 5 of the reverse flow, and the liquid zones are communicated through droplets 3j, heat exchangers 6 and 7 and ejector 9, whose input is connected to line 4 direct flow, and the output and mixing chamber to the first zones, the cooling object 8 is included in the first 4 direct flow through the ejector 9, which allows to ensure the specified conditions of cryostatisation with less refrigerant costs m pressure through line 4 passes successively through heat exchangers 6 and 7, giving up its heat to the boiling liquid, and enters the cooling object 8 About object 8, the cryogen agent perceives thermal ng load, as a result of which its temperature goes down and is directed further into the active nozzle of the ejector 9 o Kinetic energy of the expanding flow is used - is ejected in the ejector to create a vacuum and lower the temperature in subcooler 2 by pumping vapors out of it, thanks to being active. the nozzle e; vector 9 is installed at the exit of the gaseous cryogenic from the object 8, defined by the conditions of the cryostatting of the object with a high heat flux and extended hydraulic systems. y co 4 00
