Preparation and characterization of nanolubricants for refrigeration systems

The number of HVAC (heating, ventilation, and air conditioning) and refrigeration units is rising at the same rapid rate as the world's total energy consumption. The global energy situation might be drastically altered by even a little reduction in energy use. Using nanolubricants has been linked to improved heat transmission and lower overall energy usage. Researchers have imported nanoparticles into lubricants to solve this worldwide issue and enhance the efficacy of a refrigeration system. In recent years, this chapter comprehensively views the preparation, stability of nanolubrication, and characterization of lubricants, such as morphological, thermal, and rheological characterization. This chapter also aids in identifying the gaps in earlier studies and considers the prospects for further investigation. The addition of nano-sized materials and their physical phenomena influencing the vapor compression refrigeration system is confined to this chapter.
