The installation means for a device for treating, in particular humidifying and/or cleaning, a net fluid, in particular a gas, by means of a working fluid, in particular a liquid, and particularly for cooling water vapor by means of spray water and/or drip water, is provided with at least one installation package (10) of several square, waved mat elements (12) being arranged in an overlying or adjoining manner Adjacent mat elements (12) are mechanically connected to each other by pin-hole-arrangements in which pins (42) protruding from the one mat element (12) and each comprising a free end are inserted in receiving openings (34) formed in the other mat element (12). The receiving openings (34) each comprise an opening edge (36) from which a flexible clamping tongue (38) protrudes into the receiving opening (34). Each receiving opening (34) comprises an area size limited by the free end of the at least one clamping tongue (38) and the region of the opening edge (36) opposite to said end, or by the free ends of several, in particular two or three clamping tongues (38), wherein the area size (40) being smaller than the cross-section of the pin (42) in the state of the pin (42) in which the pin (42) is received by the receiving opening (34), and in which the at least one clamping tongue (38) is bend with its free end to the free end of the pin and abuts against the pin (42).

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.

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 fill in a rectilinear evaporative cooling tower includes a grid, grid support, module radial support, module column and module girts. The grid is to support a plurality of splash bars. The grid support is configured to provide support for the grid. The module support is configured to provide support for the grid support. The module column is configured to provide support for the module support. The module girts is configured to rest on a fill support frame of the rectilinear evaporative cooling tower and configured to provide support for the module columns.

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 louver assembly includes a blade array having a plurality of nested blades that are horizontally aligned, each of the plurality of blades being spaced apart from an adjacent blade by a plurality of spacers, each of the plurality of blades having a blade longitudinal axis, wherein each of the plurality of spacers is oriented at a non-orthogonal angle relative to the blade longitudinal axis.
