ABSTRACT
Nowadays, most refrigeration systems are based on vapor compression refrigeration cycle. These systems have been extensively studied and improved until today, hence enhancing the performance of these systems is rather difficult. Despite this limitation, several researches are still being carried out in order to improve the performance of these systems, and the usage of nanorefrigerants in vapor compression refrigeration systems is a most promising research field. Nanorefrigerants that are mixtures of nanoparticles and pure refrigerants are new kinds of refrigerants. In this review study, the effect of nanorefrigerants on the vapor compression refrigeration system performance is presented. It is observed that the usage of nanorefrigerants in the vapor compression refrigeration systems improves the coefficient of performance up to 43.93% and 56.32% in the theoretical and experimental studies, respectively.
