“…The result proved that, thermal conductivity of nanorefrigerant is enormously enhanced with increasing of volume fraction nanoparticle. The type of nanoparticle is not too different with other type of nanoparticle in nanorefrigerant with same of volume concentration [10]. The factor of agglomerate and assemblage of nanoparticle in nanofluids is highlighted by [12] is main element to enhanced thermal conductivity in nanofluids.…”

A boiling heat transfer is used in various industry such as power generation systems, heat exchangers, air-conditioning and refrigerations. In the boiling heat transfer system, the critical heat flux (CHF) is the important factor, and it indicated safety of the system. It has kept up studies on the CHF enhancement. Recently, it is reported the CHF enhancement, when working fluid used the nanofluid with high thermal properties. But it could be occurred nanoflouling phenomenon from nanoparticle deposition, when nanofluid applied the heat transfer system. And, it is reported that the safety and thermal efficiency of heat transfer system could decrease. Therefore, it is compared and analyzed to the CHF and the boiling heat transfer coefficient on effect of artificial nanofouling (coating) in oxidized multi-wall carbon nanotube nanofluids. As the result, the CHF of oxidized multi-wall carbon nanofluids and the CHF of artificial nanofouling in the nanofluids increased to maximum 99.2%, 120.88%, respectively. A boiling heat transfer coefficient in nanofluid increased to maximum 24.29% higher than purewater, but artificial nanofouling decreased to maximum -7.96%.

“…The system with 0.1 wt% Al2O3 added to mineral oil had 2.4% less power consumption and a 4.4% higher coefficient of performance as compared to the R-134a and POE oil system. Peng et al [28] investigated the impact of nanoparticles on the heat transfer characteristics of a refrigerant-based nanofluid, CuO/R113, flowing inside a horizontal smooth tube. The experimental results showed that the heat transfer coefficient of the nanorefrigerant was greater than the pure refrigerant and the maximum enhancement was 29.7% for the coefficient of heat transfer.…”

The performance of a domestic refrigerator with the addition of nanoparticles in the lubricant was experimentally investigated. Different sizes of nanoparticles of Al2O3 and TiO2 were added to the polyolester (POE) oil in two different volume concentrations (0.05 and 0.1 vol.%). Energy consumption tests and freeze capacity tests were then performed on the refrigerator. The investigation results showed that the refrigerator worked normally and safely with the nanolubricants. The results of the experiments indicated that the refrigerator performed better with nanolubricants as compared to pure POE oil. The COP of the systems was increased by 19% and 22% when 0.05% and 0.1% Al2O3 nanoparticles were added to the POE oil respectively. The system with 0.1% volume concentration of Al2O3 and TiO2 nanoparticles added to the POE oil consumed 27.73% and 14.19% less energy as compared to the pure POE oil system. Hence, this study showed that the addition of nanoparticles in the lubricant oil of the refrigerator is practical and it enhanced the performance of the refrigerator
