Air movement takes place because of difference in density between the air that enters inside and the one that is already inside within the tower. Natural Draft cooling towers use the design and shape of the tower itself to move up the air naturally using fans. This fan/fill geometry is also known as “Blow-through”. They are also a common feature of large air conditioning systems found in modern offices, hotels and other buildings where they are used to control the quality of internal environments – usually temperature and humidity. Natural draft cooling tower: A large tall tower which is also wide-mouthed is used for this type of cooling. In this article, we will learn types of cooling tower , working principle of cooling tower and how cooling tower works . Cooling towers are mainly divide in two categories. A basin is provided at the bottom of the cooling tower to collect the cold water which is to be reutilized. What is the Cooling Tower? Forced draft cooling tower. Open recirculation system is very popular in all types of industries because of water recycling feature. Based on the movement of Air and the Hot Water Flow these can be classified into two types: Cross flow is a design in which the air flow is perpendicular to the water flow. A cooling tower performs to cool down the water used in the industrial process. The process and the tower design are the most important factors when considering the type of packing to use.The process determines the water quality and temperature.In areas of fouled water it is important to ensure that the packing does not clog up and reduce its performance. In crossflow cooling tower, hot water sprayed from the top which is perpendicular to air which enters from the side walls of the tower horizontally and then rise upward from the center of the cooling tower. Another types of cooling tower are categorized is based on air flow pattern. The cooling industry typically categorizes cooling towers in multiple ways, including: Whether their air flows horizontally or vertically As the flow of water and air cross each others, these types of cooling tower are called as cross flow cooling tower. However, it does not mean that the quality is compromised; they are designed to serve its purpose in the best possible way. Cooling water is a utility which is used as both cold side and hot side fluid in heat exchangers depending on the temperature requirement. In this article, we will discover the different types of cooling towers and what type of applications for each cooling tower … Convection mode of heat transfer is used in the cooling tower are heat transfer takes place between air and water. Since these are smaller they only come in tonnages up to around 1,500 per cell. Some are hanging pipes in tower, some are blocked by block after gluing and some are loose round roll by ring and ring. Natural draft cooling towers use very large concrete chimneys to introduce air through the media. Cooling towers are mainly divide in two categories. Natural Draught Cooling Tower: In this type of cooling tower, fan is not used for circulating air but … At these condi- tions, the cooling tower rejects 15,000 Btuih per nominal cooling tower ton. Factors affecting the location of cooling towers, other than convenience to water supply and return, are the prevailing wind, noise, and access roads. These tall, open-topped, cylindrical structures are responsible for cooling water generated from industrial or HVAC comfort cooling process. Water cooled after heat transfer collected at basin or the bottom of the tower and hot/Warm and moist air get discharged from the top of the tower to atmosphere. Open Loop Cooling Tower - In an open loop system the water being used in the process flows through the tower exposed to the outside elements and is a part of the evaporative cooling process. The purpose of filling mater is to provides a more contact surface area for heat transfer. A cooling tower requires smaller area than a spray pond. Example 1-2. Induced draft cooling tower. For the purpose of this study, Grand View Research has segmented the cooling tower market on the basis of types, materials, applications, and region: Type Outlook (Revenue, USD Million; 2014 - … The hot water inlet is connected to a series of nozzles also know as distributor with the help of which it get spray over the fill material evenly. A nominal cooling tower ton is defined as cooling 3 gpm of water from 95°F to 85°F at a 78°F entering air wet-bulb temperature. Natural Draft Cooling Tower : It is a large tall Hyperboloid type cooling tower having wide-mouthed. It works on basic principle of heat transfer due to evaporation. This tower nozzles distribute this water to the wet chamber and simultaneously draws the dry air to process heated water. Cooling tower is an important part of power plant. Different types of cooling towers are designed for different types of purposes.Each individual type of cooling tower is made for a different application or industrial process. In induced draft cooling tower. No liquid or water is hence used for cooling in this type of setup. Natural Draft Cooling Towersare usually used for large power plants and industries with infinite coolin… What is Cooling Tower. Utilities are equivalent to the heart of any industrial process as they play an important role in maintaining adequate requirement of a product process. The cooling component of this new electricity station is a natural draft cooling tower 200 m high, the tallest cooling tower and the largest shell structure in the world. Water treatment for cooling towers depends heavily on the material that the tower system is made of, as well as the properties of the water in your area. After exchanging heat from those equipments, its temperature got increased hence it is sent to cooling tower. Cooling Tower Packing – Maintaining High Performance in Your Cooling Tower When it comes to heat transfer and more specifically, cooling water, the most efficient way is through the process of evaporative cooling. 2. Hyperboloid shape aids in accelerating the upward convective air flow, which improves cooling efficiency. Water in the tower packing, water from top to bottom, air from the bottom, both flow to the opposite of a cooling tower. Open cooling towers, also called direct cooling towers, allow the water to come into contact with outside air. 1. The water is sprayed through the pressure nozzles near the top of the tower and flows down through the fill material and. The air goes over the watercourse using the upper pool. In Forced draft system, exhaust fan placed at the base which forced the air to flow  from bottom to top of the tower. Crossflow towers. We use cookies to ensure that we give you the best experience on our website. The height of the cooling tower in thermal power plant is about 9 feet or above from the ground level. The warm and moist air is denser as compared to the cool air and therefore, it rises through the tower. Blow down loss 2. It could include; chemical plants, hotels, malls, hospitals, manufacturing plant. Packaged Type​- These types of cooling towers are assembled at a factory and are smaller than field erected towers. I have 10 years of experience in the water treatment industry. Types of Cooling Towers One way to distinguish between cooling towers is how the air and water interact, open cooling towers or closed cooling towers. There are various types of cooling towers developed to meet diverse industrial needs. Work done by the fan: air flow x pressure loss Efficient System Operation of a Cooling tower This produces low entering and high exiting air velocities, reducing the possibility of recirculation in which discharged air flows back into the air intake.This fan/fill arrangement is also known as “Draw-through”. If you continue to use this site we will assume that you are happy with it. Fresh air is induced  at bottom of the tower and which then flows in the upward direction where heat transfer takes place between warm water coming from top and and cool air coming from lower side. A Chemical Engineering professional who is learning and developing himself to get into more deeper of engineering concepts. Natural draft cooling towers 2. Below, we’ll discuss some of the different cooling tower types. According to the method adopted to circulate the air, cooling towers may be classified as: 1. Cooling tower works on the principle of evaporation. Water passes downward into the fill media parallel but opposite to the air direction which increases the contact area as well as contact time. Evaporative cooling is described as a process in which warm water from the industrial process is pumped into the tower until it reaches the distribution system. Let us discuss each of … Working principle of mechanical cooling tower is pretty much same as natural cooling tower which is principle of evaporation but the only difference is here the air is circulated into the cooling tower is through mechanical means. Evaporation loss 3. In a crossflow cooling tower, the air flow horizontally takes places. A cooling tower is one of the larger items of equipment, in terms of ground area, that must be located on a site plan. For circulation proper size fan or centrifugal fan are used.
