چکیده
The problems of thermodynamic analysis associated with the heat exchangers that used in cryogenic technology are discussed. Heat high and medium pressure air separation fluidizing plants operating at different temperature levels were selected for modelling. There many features according to which classification is made. These include such facts as number flows working fluid, relative direction substances, purpose apparatus, others. also design software design, contains calculations. general approach based on equation values efficiency characteristics restrictions imposed them At exergy method analysis, corresponding balance energy equation. On basis this balance, losses from irreversibility object its (thermodynamic) can be directly determined In a exchanger, both types exist, but it not possible reveal contribution each type total using only balance. This due fact drawn up closed control surface reflects physical logical reasons object. Meanwhile, determination technical an urgent tasks since change parameters regulate these increasing coefficient analyzed system A algorithm calculating components proposed. was calculate some two-flow exchangers. investigation obtained calculation results presented

Matrix heat exchangers and their application in cryogenic systems
The necessity of high effectiveness in a small volume has led to the development of perforated plate matrix heat exchangers (MHE) for cryogenic applications. Although the basic principles have remained the same, the techniques of fabrication and bonding have changed considerably during the last four decades. With the introduction of all metal construction, these exchangers are finding increasin...
متن کاملThermal Design Considerations and Performance Evaluation of Cryogenic Tube in Tube Heat Exchangers
Heat exchangers are the most important equipment in refrigeration processes. Design and modeling of heat exchangers operating at low temperatures are different from other regular heat exchangers. This study includes two sections. In the first section, design and modeling considerations needed for evaluating the real thermal behavior of heat exchangers at low temperatures were discussed. The...
