Embodiments of the present disclosure relate to a vapor compression system that includes a refrigerant loop, a compressor disposed along the refrigerant loop and configured to circulate refrigerant through the refrigerant loop, a condenser disposed downstream of the compressor along the refrigerant loop and configured to condense vapor refrigerant to liquid refrigerant, a subcooler coupled to the condenser, where the subcooler is external of a shell of the condenser, and where the subcooler is configured to receive the liquid refrigerant from the condenser and to cool the liquid refrigerant to subcooled refrigerant, and an evaporator disposed downstream of the subcooler along the refrigerant loop and configured to evaporate the subcooled refrigerant to the vapor refrigerant.

A flow splitter may include an inlet, at least two outlets, and an internal vane comprising a first end corresponding to the inlet and a second end corresponding to the at least two outlets, wherein the internal vane is configured to turn, between the first end and the second end, an internal flowing fluid from 0 degrees to a degree between about 60 degrees and 150 degrees. Methods of dividing fluid flow are also provided.

A water redistribution system for adiabatically pre-cooled dry coolers having stacked adiabatic panels, the water redistribution system located between upper and lower adiabatic panels and having a plurality of alternating baffles arranged to reduce water free-fall height and resultant splashing. Upwardly turned flanges at the top of each baffle inhibit the travel of water out of the interior water channel.

A heating medium injector includes an injector structure defining a heating medium flow path and a product flow path. The heating medium flow path extends to a contact location, while the product flow path also extends to the contact location. The contact location comprises a location at which the heating medium flow path and product flow path merge within the injector. In a region along the product flow path, the product flow path is defined between a first flow surface and a second flow surface. The first flow surface comprises a surface of a boundary wall separating the heating medium flow path from the product flow path and the second flow surface comprises a surface of an opposing second boundary wall. The second flow surface is in substantial thermal communication with a second flow surface cooling structure.

Embodiments are disclosed to help create longitudinal refrigerant streams, for example, in a shell and tube type evaporator, so as to manage refrigerant and/or lubricant in the evaporator. In some embodiments, the shell side of the evaporator may include a plurality of longitudinally extended pans stacked in a vertical direction. In some embodiments, refrigerant can be directed onto a top pan. The refrigerant can form a longitudinal refrigerant stream along the pan and flow down to the next pan in the vertical direction and form another longitudinal refrigerant stream. Each of the pans may form a refrigerant pool to help exchange heat with a process fluid carried in heat exchanger tubes. By forming longitudinal refrigerant streams in the pans, heat exchange efficiency may be improved and a lubricant content in refrigerant streams may be concentrated toward a bottom of the evaporator.
