Abstract

A method is disclosed for producing a heat exchanger having at least one heat transfer surface, wherein the heat is used in a thermodynamic process that uses a fluid that is condensed, expanded, evaporated, and compressed in a cycle process. The area of the heat transfer surface may be dimensioned with respect to a minimum surface area measurement of the heat transfer surface, the minimum surface area measurement being required at least for transmitting a minimum heat quantity to the fluid used with the heat exchanger in order to prevent a condensation of the fluid before, during, and after the compression process. The area of the heat transfer surface may be dimensioned based on a correlation between the molar mass of the fluid and the minimum surface area measurement of the heat transfer surface.
