摘要：
Presently, nanorefrigerant becoming the important class of nanofluids due to its heat transfer performances of refrigeration and air-conditioning systems. In the present study, we analyze the effect of shape on the thermophysical and heat transfer properties of ZnO/R-134a nanorefrigerant. The spherical and cubic shape ZnO nanoparticles used in this study for addition in refrigerant. The results of study indicate that the thermophysical and heat transfer properties significantly affected by shape of ZnO nanoparticles. In case of cubic ZnO nanoparticles, 42.5 % of increment observed over the pure refrigerant. This preliminary study about the effect of shape on thermophysical and heat transfer properties shows that ZnO/R-134a nanorefrigerant suitable for refrigeration and air-conditioning systems.
