“…Similar to that used by Peng et al [24], the experimental setup used for testing the nucleate pool boiling heat transfer characteristics of refrigerant-based nanofluid with surfactant is composed of three parts (i.e., a test section, a boiling apparatus and a condensation loop), as schematically shown in Fig. 2.…”

a b s t r a c tEffect of surfactant additives on nucleate pool boiling heat transfer of refrigerant-based nanofluid was investigated experimentally. Three types of surfactants including Sodium Dodecyl Sulfate (SDS), Cetyltrimethyl Ammonium Bromide (CTAB) and Sorbitan Monooleate (Span-80) were used in the experiments. The refrigerant-based nanofluid was formed from Cu nanoparticles and refrigerant R113. The test surface is horizontal with the average roughness of 1.6 lm. Test conditions include a saturation pressure of 101.3 kPa, heat fluxes from 10 to 80 kW m À2 , surfactant concentrations from 0 to 5000 ppm (parts per million by weight), and nanoparticle concentrations from 0 to 1.0 wt.%. The experimental results indicate that the presence of surfactant enhances the nucleate pool boiling heat transfer of refrigerant-based nanofluid on most conditions, but deteriorates the nucleate pool boiling heat transfer at high surfactant concentrations. The ratio of nucleate pool boiling heat transfer coefficient of refrigerant-based nanofluid with surfactant to that without surfactant (defined as surfactant enhancement ratio, SER) are in the ranges of 1.12-1.67, 0.94-1.39, and 0.85-1.29 for SDS, CTAB and Span-80, respectively, and the values of SER are in the order of SDS > CTAB > Span-80, which is opposite to the order of surfactant density values. The SER increases with the increase of surfactant concentration and then decreases, presenting the maximum values at 2000, 500 and 1000 ppm for SDS, CTAB and Span-80, respectively. At a fixed surfactant concentration, the SER increases with the decrease of nanoparticle concentration. A nucleate pool boiling heat transfer correlation for refrigerant-based nanofluid with surfactant is proposed, and it agrees with 92% of the experimental data within a deviation of ±25%.

“…Cu nanoparticle is one kind of the commonly used metal nanoparticles in nanofluid [19][20][21][22][23]. R113 is chosen as the host refrigerant, just as Peng et al [24] did. R113 is in liquid state at atmospheric pressure and room temperature while the widely used refrigerants (e.g.…”

“…The results showed that the R113/oil mixture with CNTs increased nucleate pool boiling heat transfer coefficient up to 61% compared to the R113 oil mixture. Peng et al [10] performed an experimental study to determine the nucleate pool boiling heat transfer characteristics of R113/VG68 oil with diamond nanoparticles. They observed that the usage of diamond nanoparticles in R113/VG68 oil mixture increased the nucleate pool boiling heat transfer coefficient up to 63.4%.…”

The topic of nanofluid heat transfer is certainly of interest to the heat transfer community. Nanorefrigerants are a type of nanofluids that are mixtures of nanoparticles and pure refrigerants. This paper focuses on five different nanorefrigerants with Al 2 O 3 nanoparticles and their pure fluids: R12, R134a, R430a, R436a, and R600a. The coefficient of performance (COP) and compressor work for various evaporation and condensation temperatures are investigated. A method is developed to estimate the performance characteristics of nanorefrigerants in the refrigerant cycles for the nonsuperheating/subcooling case and superheating/subcooling case. The enthalpy of nanorefrigerants is obtained through the density. The validation process of the proposed method was accomplished with the available data in the literature. The results indicate that COP is enhanced by adding nanoparticles to the pure refrigerant and maximum values obtained using the R600a/Al 2 O 3 mixture.
