Abstract

The study experimentally investigated the combinatorial impact of bio-based nanoparticles from agriculture waste of Citrullus Lanatus (watermelon) peels on the improvement of thermal performance and energy consumption of R600a as an alternative refrigerant to environment malignant R134a in a domestic refrigeration system. The thermodynamic system includes Copeland 46B/R600a or R134a as control and bio-based nanolubricant/R600a at different concentrations as test samples. The outcome showed that despite the results of coefficient of performance and pull-down time for the conventional R134a refrigerant fluid system, the R600a and its nanorefrigerant fluid variants performed better in terms of energy consumption, cooling capacity, and quantity of heat absorbed and expelled. Thus, reconfiguration of the thermodynamic system with bio-based nanoparticles had effect on the performance and improvement of R600a as a worthy refrigerant alternative to R134a.
