An apparatus and method for cooling, air which apparatus includes an indirect evaporative cooler, an indirect contact chiller, a reheat coil component, an ice-thermal-storage component and an ice-manufacturing refrigeration chiller to provide alternative air-flow paths and alternative component combinations. Alternative fluid-flow paths are provided through electable combinations of the several components to effect the desired lowering of air temperature, relative humidity and air density in the cooled air.

Indirect contact chiller air-precooler method and apparatus

A cooling system with at least one cooling tower and multiple upper pans or distribution manifold pipes is provided with a strainer tank assembly at the tower lower end in proximity to the sump to receive incoming fluid for cooling, which strainer tank includes a screen to strain particulate material from the inlet fluid communicated to the tower upper end and to equally distribute this fluid at the lowest elevation at a pressure with a higher static pressure component than its dynamic pressure component to avoid a requirement for a flow control valve to provide relatively quiescent fluid for fluid distribution to the tower and fluid transfer media therein. A pressure relief baffle in the strainer tank is operable in response to a fluid overpressure condition to bypass the screen and open fluid communication to avert catastrophic failures within the fluid circuit.

Cooling tower strainer tank and screen

The present invention provides an outlet connection for use in a lined basin. A structural steel basin, usually part of a cooling tower, includes a fiberglass reinforced polyester liner. Such liner is desired to provide corrosion resistance and watertightness to the steel basin. The outlet connection includes a piping section of cylindrical shape affixed to a backing plate. The piping section passes through an opening in the liner, with the backing section and another backing plate holding gaskets compressed against the liner. The piping section extends through an opening in a basin wall section, and a closure plate is affixed to the basin wall section. The closure plate also has an opening corresponding to the outer surface of the piping section, and is held to the piping section along the sides of said opening by welding or other similar means.

Outlet connection assembly

An apparatus and method for cooling, air which apparatus includes an indirect evaporative cooler, a direct-contact ice-water chiller, a reheat coil component, an ice-thermal-storage component and an ice-manufacturing refrigeration chiller to provide alternative air-flow paths and alternative component combinations. The method provides alternative fluid-flow paths through electable combinations of the several components to effect the desired lowering of air temperature, relative humidity and air density in the cooled air.

Air pre-cooler method and apparatus

Tubular containers, preferably corrugated, containing plural thermal storage medium compositions having different fusion temperatures are arrayed in zones or layers within a vessel through which liquid is circulated to exchange heat with the containers.

Thermal storage with tubular containers of storage mediums

A closed circuit evaporative fluid cooler/evaporative condenser utilizing a cross flow water-air fluid flow relationship is provided. An evaporative liquid recirculating system includes a liquid distribution spray assembly mounted above a bundle of fill sheets. A closed circuit fluid cooling/condensing heat exchanger is supported below the bundle of fill sheets. Each heat exchanger comprises a plurality of parallel coil circuits or modules, wherein the inlet of each coil circuit is at a higher elevation adjacent the air outlet side of the heat exchanger, and the fluid outlet manifold of each coil circuit is at the lowest elevation adjacent the air inlet side of the heat exchanger. This arrangement assures the coolest liquid falling from the fill sheet assembly contacts the coil assembly containing the coolest fluid and that the coolest air entering the air inlet contacts the coil assembly portion containing the coolest fluid. Each coil assembly comprises a plurality of parallel individual coil circuits each having downwardly sloped straight runs connected by return bends to assure the complete pass through and drainage of the fluid therein.

Cross flow evaporative coil fluid cooling apparatus and method of cooling

A forced draft crossflow evaporative heat exchange has a turbulent air-liquid interchange zone downstream from the air propulsion means and intermediate the air propulsion means and the heat exchange media. The media is inclined so the upper portion is closer to the air propulsion means than the lower portion.

Forced draft cross flow, free-plenum evaporative heat exchanger

A contact body or evaporative heat and mass exchanger packing composed of a plurality of side-by-side thin sheets interlocked with one another. The sheets are grooved with a serpentine-like, continuously-variable, cross section form to produce a plurality of liquid and gas channels between the sheets. The sheets have integrally-formed knobs and sockets specifically located to provide up-spaced alternate sheet support without utilizing adhesives of any type. The sheets are preferably composed of a thermoplastic material of any desired length, being continuously pressure-vacuum formed from long sheet rolls. The groove crests abut adjacent sheets apices at continuously-variable spacings of both greater and lesser dimension than the basic edge spacing of the serpentine grooves. The flat crests or apices of grooves are also infinitely variable in width dimension while maintaining a constant sidewall groove angle. The individual sheets are rotatably oriented to provide ideal bottom edge alternate sheet displacement for enhancing fluid flow.

Serpentine film fill packing for evaporative heat and mass exchange

This invention involves spaced, horizontally extending corrugations, spaced, vertically oriented film surface sheets. The surface of the fill is enhanced by molded-in angular grooves to define discrete water passageways and air turbulation ridges.

Angularly grooved corrugated fill for water cooling tower

The invention relates to an improved U-shaped splash bar fill configuration for use in crossflow cooling towers.
