Pressure Drop and Heat Transfer Characteristics of TiO2/R1234yf Nanorefrigerant: A Numerical Approach

Global warming is one of the most dangerous ecological issues facing globe. Refrigerants are a major contributor to global warming. This investigation mainly focuses on analysis greener nanorefrigerant. Nanorefrigerant can improve efficiency refrigeration and air conditioning systems that use vapor compression. In present investigation, mathematical computational methods used assess heat transfer pressure drop properties TiO2/R1234yf. order analyze characteristics transport features innovative nanorefrigerant, appropriate predictive models were adapted from earlier investigations. The validated by experiments using TiO2/POE nanolubricant as test fluid. was conducted with temperature range 10 °C 40 volume percentage nano-sized TiO2 particles in R1234yf refrigerant ranging 0.2 1%. According research, introduction nanoparticles increases viscosity, thermal conductivity, density. However, amount rises, specific capacity nano-enhanced decreases. nanorefrigerant’s coefficient improved 134.03% 80.77%, respectively. outcomes observed technique simulation approach had an average absolute variation 9.91%.
