Comparison on Simulation of Pressure Drop and Velocity Contour between Alternative Refrigerants inside Evaporator Coil using Computational Fluid Dynamics

Abstract

Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and algorithms to solve and analyze problems that involve fluid flows. The refrigeration and air-conditioning are becoming the vital area of research and development. In this project we are going to simulate, study and compare the pressure drop and flow of the refrigerants R744 and R134a with that of the R12 using CFD.R12 refrigerant is used in ?S? shaped coil of the refrigeration and air-conditioning units. The project is concluded by showing that the alternative refrigerants possess better characteristics in pressure drop and flow pattern than that of the R12 refrigerant.
