Finite Element Analysis to Determine Performance of Two Stage Vapour Compression Refrigeration System

Eswara Rao, Mrs Saritha
Refrigeration technology is based on the principle of rejection of heat to the surroundings at higher temperature and absorption of heat at low temperature. The main components of a vapor compression refrigeration system are the compressor, condenser, expansion valve and evaporator. Vapour compression refrigeration systems consume large amount of electricity. Coefficient of performance and exergetic efficiency are main two parameters to calculate the performance of refrigeration systems in the

In this thesis, comparative analysis of R134a, R152a, R600 and R600a as refrigerants in two stage vapour compression refrigeration system is performed using finite element analysis to determine the heat transfer rates, pressure loss, and mass flow rates and compared for the refrigerants COPs. 3D modeling of the two stage vapour compression refrigeration system components is done in CREO. CFD and Thermal Analysis are performed in ANSYS.
