Energy Saving FRP Fans
OverviewThe high cost of power has made manufacturers look into equipment to reduce power consumption. Cooling Towers, heat exchanger, humidification and ventilator are areas where a major saving is possible at reasonable cost for manufacturers.What is FRP Fans?Aerotech’s aerodynamically designed energy efficient FRP Hollow axial flow fans have helped in 20% reduction in power consumption and recovering the cost of fan in short time.Traditionally Cast aluminum fans consume more power due to low efficiency and heavy weight. The fans operate throughout 24 hours using excess power, which can be saved by using Aerotech’s energy efficient FRP Hollow bladed fans.Aerotech has designed and developed structurally strong FRP hollow fans which are light-in-weight with help of USA based NACA* computerized software, having more lift and low drag airfoil shape, Engineered twist, optimized chamber to increase the fan efficiency resulting a nominal low operating cost.Components of FRP FansAerotech method of Axial Flow Fan design is based on data obtained from the combination of the blade element theory, model fan tests in a wind tunnel, and tests of full scale fans in the field. The data are plotted as curves for fans of standard theory form, making the actual operation in designing the fan very short and simple. For the analysis or design of special blade which is not conforming to the standards, the modified blade element theory is used, with airfoil section characteristics, which give resultant powers and efficiencies checking the standard model data. APPLICATION OF AXIAL FLOW FANSThe axial flow fans are widely used for providing the required airflow for the heat & mass transfer operations in various industrial equipment and processes. These includes cooling tower for air conditioning & ventilation, humidifiers in textile mills, air–heat exchangers for various chemical processes, ventilation & exhaust as in mining industry etc. All major industries use large number of axial flow fans operation, such as : Cooling Towers Heat Exchangers Humidifiers Ventilation Industrial Air Circulator Man Cooler All type of Industrial Axial Flow Fan Products Energy efficient FRP Axial Flow Hollow fan Assemblies Aluminum Axial Flow Hollow fan Assemblies FRP fan Stack FRP Inlet Bell Mouth For ACC Drive Shaft Gear Box Range of FRP Axial Flow Fans: Fan diameter : 250mm to 15000mm Air Flow : 0.5 M3/s to 2500m3/s Pressure : 1mm to 100mm Tip speed Limit : Up to 70 M/s Range of Aluminum Axial Flow Fans : Fan diameter : 250mm to 5500mm Air Flow : 0.5 M3/s to 400m3/s Pressure : 1mm to 100mm Tip speed Limit : Up to 100 M/s Feature of Aerotech FRP Fans:Corrosion Free Material: The raw material i.e. Fiber Reinforced Plastics (FRP) provides the desired non-corrosive quality to the fan blades, resulting in the operation of the fans even in the chemical environment.Lightweight: FRP is Lightweight material which ensures a low moment of inertia, minimum wear & tears on motor, bearing and drive system. Hollow FRP blades is lighter than aluminum fan assembly which makes it easy to carry and due to light weight there is no possibility of damage to fan & drive during sudden stops.Tailor Made Designs: Composite structural design can be tailor made by using various glass fibers (Glass cloth & woven roving mat and roving) in right direction while moulding the fan blades with Epoxy resin thus imparting the desired mechanical strength by improving its industrial stability and enhanced mechanical properties.Aerotech design of the fan blades ensure more airflow, lower noise level & less power consumption means high efficiency. The AERODYNAMICALLY designed fan impeller of the fans, fabricated by composite material can be excellent alternative to ensure enhanced efficiency & appropriate energy saving apart from wide gamut of critical advantages.USP of Aerotech FRP Fans:HOLLOW FAN BLADES.The hollow design of fan blades The basic purpose of a “fan” is to move a mass of gas or vapor at the desired velocity. For achieving this objective there is a slight increase in the gas pressure across the fan rotor or impeller. However main aim remains to move air or gas without any appreciable increase in its pressure. The total pressure developed by the fan is of the order of a few millimeter of water gauge. A “blower” which is also referred to as “fan” in some literature deliver the gas or air with the appreciable race in pressure to overcome some kind of resistance in the flow. Some applications develop pressure of the order or 1000 mm W.G. or more. An axial flow fan stage in its simplest form consists of a rotor made up of number of blades fitted to the hub. When it is rotated by an electric motor or any other drive, a flow is established through the rotor. The actions of the rotor causes an increase in the stagnation pressure of air or gas across it. A cylindrical casing encloses the rotor.AERODYNAMIC DESIGN OF FRP HOLLOW BLADEAs mentioned previously the choice of correct twist and of special airfoil sections to reduce compressibility losses are of major importance in modern fan blades design. However other considerations still remain to be studied with care if the efficiency of the blade is to be kept at its maximum under severe operating conditions.CENTRIFUGAL AND AERODYNAMIC TWISTINGIn variable-pitch fan as described later the blades are turned in the hub about their longitudinal or pitch-change axis. Clearly the mechanism provided to produce this pitch change must be capable of exerting sufficient force to overcome any mechanical or aerodynamic opposing force set up by the blades themselves. It will be useful then to see exactly what these force are.The “mechanical force” involved is known as Centrifugal Twisting Moment (C.T.M)which as its name implies is closely allied to the normal centrifugal force acting on the blades when the fan is rotating about the shaft . It is turning couple brought about by the fact that the blade section are inclined at an angle to the fan of rotation and results in the natural tendency for any fan blade, when rotating turned about its longitudinal axis towards zero pitch so that the blades section are turned in to the fan blade rotation .THRUST AND TORQUE FORCES.The main factor that determines the force developed by an aerofoil section is the angle at which it is inclined to the relative airflow, i.e. the angle of attack in order, therefore, for the fan blade section to develop the requisite aerodynamic force for propulsion, each section along the blade must be inclined at the appropriate angle of attack to the relative airflow direction pertaining to the section hence knowing angle of attack is a simple mater to indicate the force developed as shown in figure 1) from which it will be noted that the total blade angle of attack and the helix angle.

Evaporative Condenser
The medium to be cooled is allowed to flow through tubes. Water is sprayed over tubes to form a water film surface; cool air is blown over the tube surface with help of induced draft fans mounted at the top. Temperature of both cool air and sprayed water rises, partial water will transform from liquid phase to vapor. Latent heat of vaporization water will carried out massive heat. While, a negative pressure will be formed inside the heat exchanging tube cabinet under the effect of fan’s induced draft, which will enhance the evaporation of sprayed water, thus increasing heat transfer efficiency. Non-vaporized water will be cooled down during falling into the circulation water tank. The water inlet valve will automatically refill cooling water to keep a certain water level and a normal circulating operation. While the medium to be cooled remains in a closed circulation.

Cooling Tower Cold-water Basin
The cold-water basin is located at or near the bottom of the tower, and it receives the cooled water that flows down through the tower and fill. The basin usually has a sump or low point for the cold-water discharge connection. In many tower designs, the cold-water basin is beneath the entire fill. In some forced draft counter flow design, however, the water at the bottom of the fill is channeled to a perimeter trough that functions as the cold-water basin. Propeller fans are mounted beneath the fill to blow the air up through the tower. With this design, the tower is mounted on legs, providing easy access to the fans and their motors

Cooling Tower
OverviewThis engineering note has been prepared to educating the Cooling Tower user, this deals with a very specific subjects, which Aerotech Energy Pvt Ltd appeal our capabilities to do the CT Up-Gradation Projects.Aerotech prepared the documents so that the user engineers can easily understand the cooling tower theory and possibilities to upgrade on existing Cooling TowersWhat is a cooling tower?Cooled water is needed for, for example, air conditioners, manufacturing processes or power generation. A cooling tower is an equipment used to reduce the temperature of a water stream by extracting heat from water and emitting it to the atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly. Cooling towers are able to lower the water temperatures more than devices that use only air to reject heat, like the radiator in a car, and are therefore more cost-effective and energy efficient.Components of a cooling towerThe basic components of a cooling tower include the frame and casing, fill, cold-water basin, drift eliminators, air inlet, louvers, nozzles and fans. These are described below.Frame and casing. Most towers have structural frames that support the exterior enclosures (casings), motors, fans, and other components. With some smaller designs, such as some glass fiber units, the casing may essentially be the frame. TYPES OF COOLING TOWERSThis section describes the two main types of cooling towers: the natural draft and mechanical draft cooling towers.Mechanical draft towers are available in a large range of capacities. Towers can be either factory built or field erected – for example concrete towers are only field erected.Many towers are constructed so that they can be grouped together to achieve the desired capacity. Thus, many cooling towers are assemblies of two or more individual cooling towers or “cells.” The number of cells they have, e.g., a eight-cell tower, often refers to such towers. Multiple-cell towers can be lineal, square, or round depending upon the shape of the individual cells and whether the air inlets are located on the sides or bottoms of the cells.The three types of mechanical draft towers Type of cooling tower Forced draft cooling tower: air is blown through the tower by a fan located in the air inlet Induced draft cross flow cooling tower water enters at top and passes over fill, air enters on one side (single-flow tower) or opposite sides (double-flow tower) , an induced draft fan draws air across fill towards exit at top of tower Induced draft counter flow cooling tower, hot water enters at the top, air enters bottom and exits at the top, uses forced and induced draft fans.
