A shell side condenser inlet diffuser for a vapor compression refrigeration system is provided. The diffuser includes an inlet to receive a compressed refrigerant from a compressor of a refrigeration system. A chamber is in fluid communication with the inlet to receive compressed refrigerant, the chamber having an upper side and a lower side and lateral sides bridging the upper and lower sides, the chamber having a plurality of openings to discharge refrigerant inside the condenser. A protrusion is disposed inside the chamber. The protrusion and the chamber are configured and disposed to diffuse and direct a flow of refrigerant from the compressor to inside the condenser, the refrigerant leaving the chamber having a higher pressure level than the refrigerant entering the chamber.
