Abstract

This paper investigates the reliability and performance of Vapour Compression Refrigeration System using Silica (SiO2) nano powder mixed with Polyolester (POE) oil / Mineral oil (MO) as nano lubricant and R-134a refrigerants.The aim of this work is to find which type of lubricant oil works better with SiO2 nanoparticles in the field of refrigeration. POE Oil / Mineral Oil are mixed with Silica (SiO2) nano powder by ultrasonic sonication and stirring process to prepare the nano lubricants. These nano lubricants were used in the compressor of refrigeration system instead of Polyolester (POE) oil/Mineral oil. An investigation was done on the compatibility of POE/Mineral oil mixed with Silica (SiO2) nano powder (at a concentration of 0.5%, 1% and 1.5% by mass fraction) as nano lubricant. The refrigeration system performance with the nano lubricant was investigated by using energy consumption and refrigeration effect test. The replacement of Polyol-ester lubricant by the mineral lubricant mixed with SiO2 reduces power consumption. It gives better results at mass fraction of 0.5% for all combinations of nano-oils. It is found that the freezing capacity is higher and the power consumption reduces by 13.89% when POE oil is replaced by a mixture of mineral oil and 0.5% of Silica nanoparticles. It has been observed that C.O.P. is increased by 12.16% when POE is replaced by a Nano lubricant (mineral oil + 0.5% of SiO2).Thus the above nano lubricants can be used in refrigeration system to considerably reduce energy consumption and better Coefficient of Performance (COP).
