A Study of Two Stage Cascade Refrigeration

Abstract

This paper reports the feasibility study of building a cascade refrigeration system using commercially available “off the shelf” components. The unit is to be used by a residential home or a small business with common and less expensive refrigerants and components. The research was carried out as an undergraduate project. Topics involving advanced refrigeration system is an elective course at MSU Denver. Students who participated in this project have not taken such course yet. Just in time teaching in special topics enabled the students to study the cascade refrigeration system, refrigerants behavior and natural gas behavior in order to design and build the system. As project based learning and teaching have been recognized and adopted by more and more academic units, the presented project demonstrates that complex systems can be taught, learned, and built through a project based learning process.
