Performance evaluation of refrigeration system using nano-fluid

Abstract

Abstract The objective of this paper is to investigate the influence of nanoparticles on the performance of refrigerant-based nanofluid flow through the vapour compression refrigeration system. Refrigeration systems have attracted many research activities in recent years. These systems traditionally operate with low coefficient of performance values. Other refrigerants used in vapour compression cycles may provide better performance for refrigeration cycles. Based on some research, the use of refrigeration & air conditioning systems consumes 30 to 40% of the total electricity consumed. The traditional method for increasing heat dissipation is to increase the area available for exchanging heat but it requires more space. The innovative concept of 'nanofluids' heat transfer fluids consisting of suspended of nanoparticles has been proposed as a prospect for these challenges. A refrigerant with low environmental impact and excellent thermodynamic performance will increase the performance of the system. So, R600a matches the standards and balanced nano-material (Aluminum oxide) in refrigerating systems then the performance testing of the system is going to be analyzed. By the addition of the nanoparticles to the refrigerant leads to improvements within the thermophysical properties and heat transfer characteristics of the refrigerant, thereby improving the performance of the cooling system. The experimental results show that the coefficient of performance of refrigerant-based nanofluid is above that of pure refrigerant. In considering the past researches, many characteristics behaviour are going to be implemented then experimentation is going to be administered.
