LIMITING VALUES OF THERMODYNAMIC CHARACTERISTICS OF THE LINDE CYCLE: PART 1: TRADITIONAL WORKING AGENTS

Abstract

To standardize the approach to the analysis of different cryogenic installations which utilize the Linde thermodynamic cycle, except for the energetic efficiency the intensity characteristics are investigated. The optimum pressures of direct flow, corresponding to the maximum values of the intensity characteristics and thermodynamics efficiency of a Linde refrigerator, liquefier and air separation unit have been defined. It has been proved that the optimum pressures for analogous optimization functions of different Linde installations are the same. This approach offers the possibility of using the optimum pressures, defined for a refrigerator, to calculate the maximum values of the thermodynamics characteristics for other Linde installations.
