Abstract

Binary nanoemulsion is defined as the nanoemulsion of which base fluid is a binary mixture such as NH₃/H₂O solution. The objectives of this paper are to estimate the effect of nano-sized oil droplets on the performance of a diffusion absorption refrigerator (DAR) and to find the relationship between the dispersion stability and COP (coefficient of performance) enhancement of the DAR system. The concentration and ratio of oil and surfactants are considered as the key parameters. N-decane oil is added into NH₃/H₂O solution to make the binary nanoemulsions, and C₁₂E₄ (Polyoxyethylene lauryl ether) and TWEEN20 (Polyoxyethylen sorbitan monolaurate, C₅₈H₁₁₄O₂₆) are used as the surfactants for stable dispersion. The dispersion stability of binary nanoemulsions is evaluated by the droplet size measurement and Tyndall effect analysis. It is found that the binary nanoemulsion fluid increases the COP of the DAR system as high as 15% compared with that of the base fluid refrigerator.
