TL;DR: In this paper, a comprehensive review is carried out to investigate the impact of nanorefrigerant and nanolubricant on energy saving in the refrigeration system, and the results showed that the best energy saving with 21% less energy used was with the use of 0.5% volume ZnO-R152a refrigerant nanol lubricant.

TL;DR: In this paper, thermal conductivity and viscosity of the Al2O3/polyalkylene glycol 46 nanolubricants for 0.05 to 1.0% volume concentrations at temperatures of 303.15 to 353.15 K have been investigated.

TL;DR: In this article, thermal conductivity and viscosity of the Al2O3-SiO2/PAG composite nanolubricants for 0.02 to 0.1% volume concentrations at a temperature range of 303 to 353 K were investigated.

TL;DR: In this article, the performance of an automotive air conditioning system (AAC) was evaluated by determining the heat absorb, compressor work and coefficient of performance (COP), and the results found that the maximum increase and the average COP enhancement for SiO2/PAG nanolubricants are 24% and 10.5%, respectively.

TL;DR: In this article, the viscosity and thermal conductivity of the SiO2 nanoparticles dispersed in Polyalkylene glycol (PAG) lubricants for 0.2-1.5% volume concentrations and 303-353 K working temperatures was investigated and compared with Al2O3 nanolubricant.
