Energy performance of R22 blended with nanofluids in refrigeration system

Abstract

Nanofluids are possible heat transfer fluids with enhanced thermophysical characteristics and heat transfer performance for improved performance in many devices. The thermal behaviour of air conditioning systems using various nano-fluids is described in this study. The nano-fluid chosen for testing is CuO, ZnO and Al2O3, which are combined with the R22 refrigerants with a volume fraction of 0.1 %, 0.3 % and 0.5 % to analyse the airconditioning Performance. The magnetic stirrer is used to disperse nano-particles and ultrasound for approximately 4 hours, dispersing the specified quantity into compressed oil for 2 hours to the appropriate fraction. The model uses the fluid input information to predict fluid output temperatures, operating pressures, compressor power consumption and overall system output. The experimental results show an increase in performance by using 0.5 percent volume with R22base refrigerant when using CuO
