چکیده
In this paper, an experimental work was investigated on nanorefrigerant .Nano Al2O3-PAG oil was used as nano-refrigerant in R134a vapour compression refrigeration system . An experimental setup was designed and fabricated in the lab. The system performance was investigated using energy consumption test and freeze capacity test. The results indicate that Al2O3 nano refrigerant works normally and safely in the refrigeration system. The refrigeration system performance was better than pure lubricant with R134a working fluid with 10.32% less energy used with 0.2%V of the concentration used. The results indicate that heat transfer coefficient increases with the usage of nano Al2O3. Thus using Al2O3 nanorefrigerant in refrigeration system is found to be feasible.

Heat transfer enhancement in domestic refrigerator using R600a/mineral oil/nano-Al2O3 as working fluid
f liquid g gas ABSTRACT The experimental apparatus was build according to the national standards of India.. The performance of the refrigeration system depends upon the heat transfer capacity of the refrigerant. Normally R12, R22, R600, R600a and 134a are used as a refrigerant. This refrigerant heat transfer capacity is not so good and increase power consumption. Due to these limitation nanoflu...
