Abstract
This study presents a 40g R600a charge enhanced with various TiO2 nano-lubricant concentrations (0 g/L and 0.2 g/L nano-lubricants) infused into an R12 domestic refrigerator tested within selected ambient temperature conditions (19, 22 and 25 ºC). The performance test parameters including: energy consumption, discharge pressure, power per tonne of refrigeration (PPTR) and coefficient of performance (COP) were evaluated for the system. The results showed that infusing the nanolubricant into the system improved the energetic performance of the system. Overall, the use of 40g at 25ºC gave the best performance within the system. In conclusion, application of nanoparticles in refrigeration systems was found to improve the performances of the system even with the effect of ambient temperature. R600a-TiO2 nano-lubricant mixture works safely and efficiently in the domestic refrigerators but requires adequate optimization.
