ABSTRACT
Several studies were conducted in the literature related to the application of nanoparticles in refrigeration, heating, ventilation, and air conditioning (HVAC), heat pumps, and other thermal systems to enhance the efficiency and reliability of these systems due to the superior thermophysical characteristics of nanoparticles. The boiling behavior of the refrigerant-based nanofluids, both pool boiling and two-phase flow boiling plays a major role in affecting the performance of the refrigeration, HVAC, and heat pumps systems. The addition of nanoparticles into phase change fluids may enhance the boiling heat transfer performance of many thermal systems. The application of nanorefrigerants in refrigeration, HVAC, and other systems will lead eventually to a smaller refrigeration systems and consequently less compressor power consumption. Studies regarding flow condensation heat transfer phenomena in nanorefrigerants are very limited and more investigations should be conducted. Several experimental studies were conducted in the literature associated with the effect of adding nanoparticles to refrigerants on the nucleate pool boiling heat transfer.
