This research addresses the critical requirement for effective and demonstrable vapour absorption refrigeration system (VARS) test equipment. The existing lack of complete and effective teaching equipment impedes understanding of VARS principles. This study intends to fill that void by creating and implementing a VARS test rig, specifically designed for efficient classroom demonstrations. A systematic computational technique is used in the research to design and create VARStest rig for instructional objectives. Rigid thermodynamic analysis, system modelling, and prototype production are all parts of the technique. Computational simulations drive crucial component optimisation, assuring the rig's efficacy in demonstrating the fundamental principles of vapour absorption refrigeration. The suggested test rig combines theoretical principles with hands-on experience, allowing for a thorough knowledge of VARS in educational contexts.
