Design and implement of tow stage vapor compression refrigeration system for fresh frozen plasma storage

Abstract

The purpose of the project is the design an implement of two stage vapor compression refrigeration cycle whit intermediate vessel and double throttling, for storage of 10 kg of frozen plazma, that used in medical applications, and save it at -35 c refrigeration space. The refrigerant R404 A was selected as suitable working fluid. This system consists of two cycles connected in series, where the higher cycle operates between (-8 and 45 c_, and the low cycle operates between ( -45 and -8 c). Full theoretical design and building of the system will be made, including the full automation for the cycle and controlling of its componants.
