Abstract

The concept of mixed refrigerant fluids has emerged during the past few decades from 20th century due to its superior thermophysical properties as compared to base fluids. It is primarily used as coolants in heat transfer equipment such as heat exchangers and thermoelectric cooling systems. In the current study, an analysis of the physicalthermodynamic properties and the different parameters was performed by considering 10gms of mixed refrigerant of propane and ISO-butane at different compositions ratio. All results presented for simulations carried out at range temperature about 300-350K and a pressure range of 3MPa to 7MPa. They concluded from the result that as the temperature increases specific heat of mixed refrigerant decreases. Similarly, thermal conductivity increases with an increase in temperature for a mixed refrigerant at different compositions. Further, as the pressure is varied from 3MPa to 7MPa while keeping the temperature constant at 350K, the specific heat decreases by 5.2% as well as thermal conductivity follows the opposite trend and is increased by 6.9%.
