The fill(made of plastic or wood) adds surface area and slows water descent to encourage evaporation and heat transfer between the air and water. A cooling tower system can be one of the biggest energy consumers within a facility. Choices include: 1. corrugated sheet 2. plastic balls 3. ceramic balls 4. mesh pads for particulate removal and mist elimination Typically, corrugated sheet is available as paper, foil, or film. For thermal performance levels typically encountered in air For cooling towers, mechanical equipment that cools water produced by industrial processes like chemical processing and food processing, this is especially true. Water Treatment Media (such as Tube Settler, MBBR Media, Bio Ball Media, Diffusion Aerator etc.) Cooling towers can be classified in two types 1) Natural Draught Cooling Tower: In this type of cooling tower, fan is not used for circulating air but here, by enclosing the heated air in the chimney and it will create pressure difference between heated air and surrounding air. MX is a hanging film type cooling tower fill which spreads the water into a thin film, flowing over large vertical surfaces, promoting maximum exposure to air flow. UNLIMITED The water quality, water temperature and cooling tower design dictate which pack to select as well as considerations for removal and maintenance. The smaller the flute size, the larger the surface area per m2 therefore the larger the film of water, creating  a higher potential heat rejection per m2. Include me in third-party email campaigns and surveys that are relevant to me. Using the incorrect packing can seriously hamper system performance and cause overflow issues if water is directed through the pack in the wrong direction. Plastic packing has brought many advantages, but most notable is its efficiency. Using an anti-legionella packing material provides additional protection in areas of the cooling tower that water treatment doesn’t reach but is not a replacement for an appropriate water treatment regime. Calculate The Overall Volumetric Mass-transfer Coefficient Kya That Can Be Used To Design A Large, Packed-bed Cooling Tower, Where A Is The Mass-transfer Area, A, Per Unit Volume, V, Of Tower. Installing modular packing, that can easily be removed, makes cleaning and future replacement far easier. Today, evaporative cooling adopts exactly the same principles but uses technological advancements in materials and design to further improve this efficient method of cooling. In basket held pack, the baskets are often plastic coated wire, which over time degrades, exposing the wire which causes corrosion in the tower. Counterflow diagram. The pressure drop encountered in FBCT is comparable to that of conventional cooling towers. The distance between the top of the cooling tower packing and the bottom of the fan should be 1.2 times the diameter of the fan. It is important to select the most suitable cooling tower pack when replacing to at least maintain the design duty of the cooling tower. It should be noted that it is possible to have an open circuit tower (with heat transfer pack) but create a closed circuit through the introduction of a heat exchanger, which achieves separation of the process side and cooling side of the system. The process and the tower design are the most important factors when considering the type of packing to use. In vertical fills, as the name suggests, the flutes are arranged vertically. The packing height in FBCT reduces considerably because of fluidization. ACCESS BEST IDEAS. Use of this website signifies your agreement to our Terms of Use. Features of PVC Cooling Tower Fill Packing Media. What is Evaporative Cooling? This cooled air would then be discharged into buildings, providing the origins of comfort cooling. It is also lightweight, making it easier to handle and therefore encourages replacement and regular removal for cleaning. size Fluidized Bed Cooling Tower (FBCT) is found to be encouraging. ♦ First, the cross-flow cooling tower standard size. These types of cooling towers are factory preassembled, and can be simply transported on trucks, as they are compact machines. These come in various sizes, typically ranging from 12mm to 38mm. Here are some categorizations. Water is circulated over a coil within the tower, which through input from the fan delivers evaporative cooling to the process loop, which in turn, returns cool water to the application. Changing out the packing also provides the opportunity to look at more efficient packing if required or an open mesh pack if the water is particularly fouled. Passive or natural draft cooling towers combine the upward motion of warmed air with a steep chimney architecture to organically pull air throughout the tower. Approximately half of the fill used in crossflow cooling towers, and virtually all that which it utilized in counterflow cooling towers is film-type. If the pack is changed out then it’s important to ensure that the replacement pack at least meets this original duty. Tower packing is a mass of inert, solid shapes.
