Experimental Refrigeration Test of R134a Mixed With Mineral Oil and (Cuo) Nanoparticle

Authors(2) :-M. Nagaraju, V. Mahanandi Reddy

Evaporating heat transfer is very important in the refrigeration and air conditioning systems. But refrigerant were used in refrigeration process and they were having a global warming coefficient at high level, Though the global warming up potential of HFC134a is relatively high, it is affirmed that it is a long term alternative refrigerants in lots of countries. By addition of Nano particles to the refrigerant results in improvements in the thermo physical properties and heat transfer characteristics of the refrigerant, thereby improving the performance of the refrigeration system. In this experiments comparing the effect of using, CuO-R134a & mineral oil in the vapour compression system on the evaporating heat transfer coefficient. Polyester Oil was tested along with suitability and environmental friendly refrigerant R134a. Results show that Cuo nanoparticle concentration of 0.8wt% is optimal and gives highest heat transfer enhancement and improve the coefficient of performance (COP). An experimental apparatus was build according to the national standards of India. Nano Cuo concentrations ranged from 0.05 to 0.8% and particle size from 10 to 70 nm. The results indicate that evaporator heat transfer coefficient increases with the usage of nano CuO. But economically cost for nano refrigerant.
