摘要

In this study, the performance of TiO2 and Al2O3 nanoparticles with R1234yf refrigerant in a vapor compression refrigeration system is investigated. Nanoparticles are an effective approach to achieving energy savings while simultaneously reducing emissions. Using R1234yf refrigerant at varying mass concentrations and operating settings for TiO2 and Al2O3 nanolubricants, experiments were carried out to evaluate the performance of vapor compression refrigeration systems. In this study, the thermodynamic and environmental performances of single-type nanoparticles (TiO2 and Al2O3) used at concentration (0.5 mass%) in vapor compression refrigeration systems (VCRS) were investigated. The system with TiO2 nanolubricant showed the best cooling capacity performance at 0.5% by mass concentration, with an average improvement of 12% and 28.1% power consumption reduction. Al2O3 nanolubricant, at 0.5% mass concentration, achieved 9.1% higher performance improvement and 25.7% power consumption reduction. When POE was used to assess the VCRS’s energy efficiency, an improvement of 22.4% was achieved with 0.5% TiO2 nanolubricant by mass. The most favorable exergoeconomic outcome was seen for the 0.5% TiO2 nanolubricant, with an increase of 28.16% compared to POE. The best environmental performance was achieved with a 28.1% reduction in the 0.5% TiO2 single-type nanolubricant by mass. In summary, the nanoparticle has a good impact on the VCRS performance in a variety of ways.
