Cop Enhancement of Vapour Compression Refrigeration System

This experimental investigation exemplifies the design and testing of diffuser at compressor inlet nozzle condenser outlet in vapour compression refrigeration system with help R134a refrigerant. The divergence angle 12°,14° convergent are designed for same diameters. Initially diffusers tested is used diameter equal to exit tube evaporator suction compressor. Diffuser helps increases pressure refrigerant before entering it will be reduces work achieve higher performance system. Then nozzles outlet, whereas discharging expansion valve. Additional drop helped analyzes using first second laws thermodynamics, determine refrigerating effect, input, coefficient (COP).
