Abstract: An evaporator including a shell having a first end and a second end. A plurality of tubes are disposed within the shell to circulate refrigerant through the shell. A plurality of shell inlets are in fluid communication with the shell to deliver a fluid to exchange heat in the plurality of tubes, preferably through a baffle arrangement. At least one of the shell inlets may be arranged to deliver fluid to the shell adjacent to the first end. In addition, at least one of the other shell inlets may be arranged to deliver fluid adjacent to the second end. A shell outlet is in fluid communication with the shell to discharge fluid from the shell. The shell outlet is arranged to receive the combined liquid delivered to the shell by the plurality of shell inlets.

Abstract: 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.
