Title

Effect Of Inlet Temperature On The Heat Transfer In Mixed Refrigerants With Variable Composition

Authors

Abstract

Refrigerants used for industrial cooling and domestic refrigeration occasionally results in decrease in Coefficient of Performance due to increase in cooling loads. As the mass of the refrigerant used, remains constant because of the fixed compressor capacity, therefore use of mixed refrigerants can prove to be a feasible solution to cater to the needs of cooling. Hence the present study aims at usage of mixed refrigerants R290 and R600a in industrial cooling systems. The objective of this project is to estimate heat transfer and temperature difference associated with the previously mentioned mixed refrigerants computationally. For this study, use of ANSYS FLUENT software is proposed. The operating pressure is set to be 3 MPa in a pipe of 0.064m diameter while simulation because higher pressures are maintained in the industrial cooling system. At fixed wall temperature of 350K, mixed refrigerants with varying composition is simulated in FLUENT. Initially, composition of 10% R290 and 90% R600a is selected and with varying Rate of flows i.e. from 0.05 kg/sec to 0.1 kg/sec, simulation is performed and heat transfer is estimated. After this step, simulations are performed for 20% R290 and R600a composition and composition is progressively increased to 90% R290 and 10% R600a. The analysis is then extended for corrugated pipes to obtain optimized results of heat transfer and temperature difference. Finally, Reynolds number and Nusselt number is calculated from Temperature difference and Heat transfer.
