Except to increase the whole system efficiency stress are done on particular parts of system and research are done on that systems. Air separation unit and compressor, condenser and evaporator of cryo system are the center of research because most of exergy destruction takes place in these parts. After reviewing literature it conclude that every part of system has its own and equal importance because ones effect on another whether it is small or big create a lot of difference in proper analysis of system. Ignoring one small system due less effect can put gap in complete research analysis of system that why it quite important take all parts of system as one and finding out the every part impact on another to calculate right equation for high output. Heat exchanger and expansion valve, expander and other addition parts should also properly analyze. Advanced technologies are used in very limited way and only on some part of system. From literature it noticed that exergy efficiency depend upon mainly upon the inlet condition of the system but which inlet condition best suit for a particular type of the system that is main work of research This paper mainely deal with thermodynamic (exergy and anergy) analysis cryo-systems component wise and influence of Non-ideal components on cryo systems.
