“…Using SWCNT/R134a nanorefrigerant, [37] observed the viscosity of the nanorefrigerant increases as the concentration increased. [64] reported that the viscosity of Al2O3/R134a nanorefrigerant of nanoparticle size 20 -30 nm with a volume concentration of 0.01% and 0.02% increased as the concentration increased. An increase of 1.4% and 5.2% was obtained for 0.01% and 0.02% particle concentration respectively.…”

Refrigerants are commonly used as heat transfer fluid in refrigeration, heat pumps, and air conditioning systems. Nanorefrigerants are a special kind of nanofluid synthesized by dispersing nanoparticles into refrigerants or lubricant oil to improve its thermophysical and heat transfer characteristics. The optimization of the thermophysical properties of nanorefrigerant strongly depends on the successful synthesis procedures used for producing a stable suspension of nanoparticles in the refrigerants. In this study, a review was carried out to understand the synthesis of nanorefrigerant and the effect of nanoparticle size, type and concentration, temperature, base fluid type on the thermophysical properties of the nanorefrigerant. The effect of nanorefrigerant on the pressure drop and boiling heat transfer within the vapour compression refrigeration system (VCRS) was reviewed. From the review, the thermophysical properties of the nanorefrigerants affect the pressure drop and heat transfer characteristics of the vapour compression refrigeration system.

“…The refrigerating effect is elevated because the thermal properties of Ag-doped nano-CuO are better than pure nano-CuO. Also, the overall conductivity of the refrigerant is also increased due to the nano-transitional elements mixed with it [22,23].…”

Refrigerators are inevitable in domestic and many industrial habitats. Indeed, the performance of refrigerants used in refrigerators can be enhanced when mixed with nanoparticles. In this regard, this study uses cupric oxide nanoparticle to enhance the refrigerant performance. Pure nano-cupric oxide and silver-doped nano-cupric oxide are mixed with R290 in the ratio 1:100. The doped nano-cupric oxide is characterized by XRD followed by EDX. TEM is used for photographic verification of nano-size, and the DRS test is used to calculate and compare band gap. The refrigerator gives better results with the prepared nano-refrigerants. The result is much better with silver-doped nano-cupric oxide than with pure nano-cupric oxide. The coefficient of performance of silver-doped nano-cupric oxide increased up to 29%. On the other hand, the power consumption of the refrigerator is also found to reduce up to 28%, thus helping save energy.
