Ciclo termodinámico según un ciclo brayton con refrigeración ambiental próxima a la isoterma critica del fluido de trabajo, que evoluciona en un ciclo cerrado entre una presión de baja y una presión de alta.

摘要

Closed regenerative cycle, the minimum temperature of the working fluid of which is in turn close to the critical temperature but greater than the latter and close to the ambient temperature used to cool the cold source; with the value of the high isobar which coincides with the so-called supreme isobar, which has the maximum average specific heat value at a constant pressure, within the peri-critical zone, above the critical isotherm and is delimited in terms of pressure between a fifth and five times the critical pressure, being selected, setting the low isobar by providing the maximum of a ratio in which the numerator is the specific work and the denominator is the sum of the absolute values of the specific enthalpy variation of each stage of the cycle.
