Abstract: In various embodiments, the present invention relates to heat dissipation systems including a hygroscopic working fluid and methods of using the same. In various embodiments, the present invention provides a method for heat dissipation using a hygroscopic working fluid. The method can include transferring thermal energy from a heated process fluid to the hygroscopic working fluid in a process heat exchanger, to form a cooled process fluid. The method can include condensing liquid from a feed gas on a heat transfer surface of a feed gas heat exchanger in contact with the cooled process fluid, to form a cooled feed gas, the heated process fluid, and a condensate. The method can include dissipating thermal energy from the hygroscopic working fluid to a cooling gas composition with a fluid-air contactor. The method can include transferring moisture between the hygroscopic working fluid and the cooling gas composition with the fluid-air contactor. The method can include adding at least part of the condensate to the hygroscopic working fluid.

Abstract: A cooling tower splash bar hanger assembly includes a grid comprised of a plurality of wires, including vertical and horizontal wires, defining a plurality of slots. The plurality of vertical wires includes a first vertical wire and a second vertical wire. The plurality of slots includes a first slot. The first slot defines a first slot width. A first splash bar defines a first bar width and is configured for positioning in the first slot supported by one of the plurality of horizontal wires. A second splash bar defines a second bar width. The second splash bar is supported by the one of the plurality of horizontal wires. The first slot width is greater than the first bar width and the second bar width. The first slot width and the first bar width define a size ratio of approximately two to one or greater than two to one.

Abstract: Trickle bodies for the air conditioning of, in particular, animal housings, that possess only partially latticed layer elements. Trickle bodies are formed of a plurality of sandwiched layer elements that, in known trickle bodies, are formed of corrugated and completely latticed plastics foil. The trickle bodies formed of such layer elements possess a relatively low stability and a limited evaporation capacity. The plastics-formed layer elements of the instant invention are produced by injection molding, allowing layer elements having corrugation heights of more than 12 mm to be formed. Such trickle bodies are more stable, enable a high evaporation capacity and are, moreover, also less permeable to light.

Abstract: 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.

Abstract: A drift eliminator to remove liquid from a flow of air in a cooling tower includes an eliminator inlet, a plurality of flutes, an eliminator ridge, and a plurality of ribs. The eliminator inlet is to receive the flow of air. The plurality of flutes are configured to convey the flow of air through the drift eliminator. The eliminator ridge has a first drift wall extending in a first direction and a second drift wall extending in a second direction. Each flute is in fluid communication with the eliminator ridge and is defined by a flute interior surface curving upwards from the flute inlet to a flute outlet. The plurality of ribs are defined by adjacent ones of the flutes and curving upwards toward the flute outlet.

Abstract: A support beam for a cooling tower fill assembly includes a web, an upper flange, a lower flange, and a lip. The web has a serpentine shape so a lower end of the web is vertically offset relative to an upper end. The upper flange extends from a first side of the web at the upper end thereof. The lower flange has a first portion extending from the first side at the lower end thereof and a second portion extending from a second side at the lower end thereof. The lip extends upwardly from the second portion so the lip cooperates with the second portion and a portion of the web to form a longitudinal channel. The lip and the second portion are provided with a plurality of spaced apart notches.

Abstract: The present application provides a method of evaluating media effectiveness in a gas turbine engine. The method may include the steps of receiving a baseline media effectiveness rating, receiving a media replacement cost, receiving a number of operating parameters from a number of sensors, based at least in part on the operating parameters and the baseline media effectiveness rating, determining a media effectiveness model, based at least in part of the media effectiveness model, determining a loss in evaporative benefit cost over time, determining a time t when the loss in evaporative benefit cost exceeds the media replacement cost, and scheduling media replacement at time t.
