Summary

The growing need for thermal comfort has resulted in an increase in refrigeration systems and, as a result, increased electricity demand for these systems. Waste heat-driven devices for refrigeration systems appear to be a potential alternative to traditional compression-based refrigeration technologies for reducing energy consumption. These devices in the refrigeration cycle can be driven by waste heat (free or inexpensive low-temperature energy source) as the primary energy source instead of electricity. This study investigates the ejector-driven and converging Tee-driven refrigeration systems (EDRS & CTDRS) using waste heat, aiming to provide an alternative to traditional VCC. An experimental setup is developed with a 3.6 mm nozzle size of an ejector and a converging tee diameter of 12.7 mm. A comparative experiment was conducted to assess the coefficient of performance (COP). In terms of performance, the EDRS COP outperformed the converging-tee-driven refrigeration cycle. The results showed that the proposed concept is promising to develop an alternative to the traditional refrigeration cycle and heat recovery.
