Performance Analysis of Air Conditioner using R290 as Refrigerant with and Without Nanoparticles

Abstract

R22 is commonly used refrigerant in air conditioning systems. These HCFC refrigerants have negative impact on the environment which causes ozone depletion. Hence the usage of these HCFC refrigerants needs to be avoided. An alternative refrigerant need to be evaluated as an alternative to these HCFC refrigerants and R290 is suitable as alternative refrigerant due to its low ODP and low GWP. In this, Cu doped MgO Nanoparticles are synthesized and the nanoparticles are used for the preparation of Nano-lubricant with different concentrations. An experimental investigation is performed on the air conditioner using R290 as refrigerant with and without Cu doped MgO nanoparticles in compressor lubricant oil. The system performance is analyzed and compared with and without using nanoparticles based on the performance parameters such as refrigeration effect, compressor work input and COP.
