Abstract

This investigational analysis exemplifies the design and test of diffuser at compressor inlet and nozzle at condenser outlet in VCR with the help of R134a refrigerant. The diffuser with divergence angle of 12°, 14° and the nozzle with convergent angle 12°, 14° is designed for same inlet and outlet diameters. Initially diffusers are tested at compressor inlet diffuser is used with inlet diameter equal to exit tube diameter of evaporator and outlet tube diameter is equal to suction tube diameter of the compressor. Diffuser helps to increases the pressures of the refrigerant before entering the compressor it will be helps to reduces the compression work and achieve higher performance of the vapour compression refrigeration system. Then nozzles are testing at condenser outlet, where as nozzle inlet diameter equal to discharging tube diameter of condenser and outlet diameter equal to inlet diameter of expansion valve. Extra pressure drop in the nozzle helped to accomplish higher performance of the vapour compression refrigeration system. The system is analyse using the I^st and II^nd laws of thermodynamics, to resolve the refrigerating effect, the compressor work input, coefficient of performance(COP).
