Abstract

Values of the minimal expenses in the cryogenic plants is determined by using the representation of reversible cycles and processes. It is shown that the determination of the minimal energy expenses in refrigeration and liquefaction cryogenic plants can be obtained without the use of the corresponding ideal cycles. A numerical method for calculation of the minimal energy expenses of the evaporator, when the refrigeration temperature is variable, has been proposed. The expressions for the calculation of the minimal energy expenses in the evaporator and the collector of fluid in the accounting losses from irreversibility of processes in these elements were obtained.
