Design and Building of Refrigeration System for Refrigerated Chambers at Three Temperature Levels

Abstract

The project presents the design and implementation of three refrigerated chambers, the total volume of the chambers is about 200L for storing 30kg meat, 30 kg cucumber, and 35 kg lemon,single stage vapor compression refrigeration cycle with multi evaporator swill be used for maintaining the required temperature in the champers , every chamber has a different temperature ( 0,5,8)c. Full theoretical design and selection for each component , the design paid attention foe ecological and environmental aspects in selecting the refrigerant , so R-134 a presented the best refrigerant that is used. The control of the system will be done by using traditional automation components with the possibility of improving the system by using direct digital controller ( DDC) or programmable logic controller ( PLC). The system will be built and tested to make comparison between theoretical and actual results.
