Abstract

An alternative mode of generation of low temperatures that may be called nearcryogenic ones (from -90 to -120 оC) is described. A constant toughening of legislation in the sphere of refrigerants circulation necessitated the use of refrigerating machines operating on natural working substances to generate a large range of temperatures. To supply cold at abovenamed temperatures at small needed refrigeration capacity it is offered to use the carbon dioxide sublimation at vapors vacuum pumping in a vacuumsublimation plant. A mathematical model describing the process of cooing of a working substance solid mass is offered to forecast the dynamic characteristics of such a plant. The paper cites the results of numerical solution of the mathematical model and the experimental data as well.
