Concerns about the environmental impact of refrigerants used in vapour-compression refrigerators, have prompted the Stirling-Cycle Research to investigate the feasibility of low-cost Stirling-cycle machines that use air as the refrigerant. Such machines theoretically have the highest efficiency possible for any practical thermodynamic system, and thus provide a tempting alternative to traditional vapour- compression technology. This paper outlines the working principles of Stirling-cycle on refrigeration system. The focus of research is kept on analysis of effect of regenerator length, regenerator Diameter, wire mesh size, wire mesh arrangement, and wire mesh material on Coefficient of Performance and Heat Transfer Rate.
