Abstract

In this study, an experimental setup is designed and built to investigate the feasibility and performance of the proposed dual-mode cascade refrigeration cycle. The apparatus can be operated in two modes: dual-stage mode and single-stage mode such that the low temperature cycle (LTC) can be operated together with the high temperature cycle (HTC) or can run independently. Experimental results validate the feasibility of independent operation of LTC. The performance of the independent operation of LTC mode is theoretically investigated using experimental data as bases. Detailed suggestions are made for the improvement of the coefficient of performance (COP) of the experimental system. Theoretically, high COP of the cycle provides excellent application for the presented refrigeration cycle.
