A tube heat exchanger extending in a vertical direction, comprising: a first chamber including a lower portion provided with at least one intake inlet for a diphasic fluid including a liquid and a first vapor containing a mist; an upper portion; and a first recovery member passed through by the first vapor and recovering the mist in liquid form, the first vapor next arriving in the upper portion, a central chamber forming liquid films running over the tubes and vaporizing at least partially to produce a second vapor, the tubes being traveled inwardly by a fluid hotter than the diphasic fluid, and a second chamber receiving the first vapor and the second vapor to form a third vapor, and including an outlet for the non-vaporized liquid and an outlet for the third vapor, the first chamber and the second chamber together forming a volume surrounding the central chamber around the vertical direction.

A heat exchanger for a heating, ventilation, air conditioning, and refrigeration (HVAC&R) system includes a shell having an inlet configured to receive refrigerant and an outlet configured to output the refrigerant. The heat exchanger also includes a refrigerant distributor disposed within the shell, and multiple evaporating tubes disposed within the shell and positioned below the refrigerant distributor. The refrigerant distributor includes a perforated plate having multiple holes, each hole extends from a top surface of the perforated plate to a bottom surface of the perforated plate, and a center point of each hole is substantially aligned with a centerline of a respective evaporating tube.

A fill pack includes a first sheet and a second sheet. The first sheet has a first end, a second end and a first plurality of flutes. A first microstructure includes first top flat strips, first bottom flat strips and first conduit sides connecting the first top flat strips to the first bottom flat strips. A plurality of first radii connect the first top flat strips to the first conduit sides and the first bottom flat strips to the first conduit sides. The second sheet has a second plurality of flutes. A second microstructure includes second top flat strips, second bottom flat strips and second conduit sides connecting the second top flat strips to the second bottom flat strips. A plurality of second radii connect the second top flat strips to the second conduit sides and second bottom flat strips to the second conduit sides.

A fill sheet for cooling heat transfer fluid in a cooling tower includes an air intake end, an air outlet end, a top edge and a bottom edge. The air outlet end is positioned opposite the air intake end along a lateral axis. The top edge connects the air intake end and the air outlet end and the bottom edge also connects the air intake end and the air outlet end. The bottom edge is positioned opposite the top edge along a vertical axis. A plurality of flutes extends generally parallel to the lateral axis between the air intake end and the air outlet end. An offset extends generally parallel to the vertical axis. A first flute of the plurality of flutes transitions from a first peak at a first side of the offset to a first valley at a second side of the offset.

A pre-evaporative system used with an evaporative cooling apparatus is provided. The system may include a pre-evaporative media and a cooling media, each having a fiber pad with an edge coating and a distribution plate. The distribution plate operates to evenly distribute water over the entire surface. The system includes a shield with a mounting plate. The shield with the mounting plate operate to retain the pre-evaporative media and the cooling media adjacent each other; to form a seal with the distribution plate of the pre-evaporative media and with the distribution plate of the cooling media; and to shield a first water distribution pipe and a second water distribution pipe that supply water to the pre-evaporative media and the cooling media.

High performance ceramic (HPC) cooling tower fill plates with scalloped top and bottom edges and cross-hatched veins are used in combination with improved retainers in order to produce high performance, cooling tower fill bundles.

In various embodiments, the present invention relates to heat dissipation systems including a hygroscopic working fluid integrating waste water as makeup water. The present invention also relates to methods of using the same. The present invention also relates to hygroscopic cooling systems adapted to dispose of waste water by combining the waste water with a hygroscopic working fluid, precipitating impurities and evaporating the remaining water.

A hybrid wet/dry cooling tower and novel splash fill material are provided. In one embodiment, the cooling tower includes a wet cooling section having a draft fan disposed above the wet section for drawing air through the wet section to cool liquid traversing the wet section. The cooling tower also includes a dry cooling section disposed laterally adjacent the wet section and configured to enable the draft fan to draw air through the dry section. In another embodiment, the dry cooling section has one or more added draft fan(s) for drawing air through the dry section with or without operation of the draft fan disposed above the wet section. In other embodiments, different structures and configurations of plastic splash fill material are described.
