Abstract

A new method for improving the characteristics of cryogenic systems, based on the use of step with the heat machine is offered. The machine work is organized in the field of cryogenic temperatures. An additional cooling stream of an actuating medium with the help of a heat machine is made for the purpose of decrease in losses at it its throttling. The possibility of a substantial increase their characteristics is confirmed on the example of the refrigerator and liquefier Linde. It is shown that cold production of refrigerator increases on the size equal to work of the heat machine. The growth rate of liquefaction in the Linde liquefier is equivalent to the work made by heat machine. It is possible cooling and exergy efficiency of the nitrogen refrigerator Linde increase in 2,4 times when using a heat machine.
