Recirculating Cooling Water (RCW) systems are by far the most common type of cooling water systems in process industries, refinery units and petrochemical plants. The main cooling system principles are: Open or closed system, designates whether the coolant is allowed to contact the environment or not. After exiting the heat exchanging coil, the chilled water return (CHWR) returns to the chiller, where it is cooled again, and the process repeats. The main components of RCW systems include the cooling tower and the HEN. If a water treatment system is needed at this part of the cooling tower water process, it is usually technology that removes hardness and silica or stabilizes and adjusts the pH. However, conventional centrifugal chillers cannot always operate with cooling tower water below a 65ºF temperature limit. Some chilled water cooling system configurations are very simple, while others are more complex: A simple chilled water cooling system configuration can consist of a single chiller and a single pump. A Cooling System is a Critical Plant Utility Just like your plant electrical system, telecommunications equipment, or data network infrastructure, a process cooling water failure can shut down a facility and may even involve safety issues.

Here are the basic types: A once-through cooling system pumps water into equipment where it passes over a hot surface in order to cool it . This manuscript presents a technique for grassroot design of cooling water system for wastewater minimization which incorporates the performances of the cooling towers involved. Process Chilled Water Systems (PCW) are compact, skid mounted systems that circulate process water at a consistent temperature and pressure to the application’s point of use and back, allowing for more efficient and stable use of water-cooled machines, equipment and instruments. 2: p-h Diagram. The cooling water used in the heat exchanger network returns to the cooling tower where the hot return cooling water is cooled ().Blowdown is necessary to avoid the build-up of undesirable materials in the re-circulating water as a result of evaporation. The cooling water system consists of the cooling tower, re-circulation system and heat exchanger network. 1, the capital cost in $ year-1, including chemical engineering index and animalization factor, a function of water flowrate in t h-1.The approach, range and wet bulb temperature are in °C. Water temperatures from 40 F to 75 F (Depending on water cooling method, chiller or cooling tower.) Industrial cooling towers can be used to remove heat from various sources such as machinery or heated process material. Conventional design of cooling water networks utilises parallel configuration (Fig. In any case where unwanted heat is generated, it is necessary to design a suitable cooling system that is capable of absorbing… S&S Technical is a leading manufacturer of (PCW) Process Chilled Water Systems for multiple industries. 5. Of these methods, recirculating cooling water systems are the most common ones because of their important role in conserving fresh water and reducing thermal pollution compared to once-through systems (Kim et al., 2001). The concept or methodology used in the design of water chiller. Water is cooled during downward motion by contact with air blown upwards, which can bring the water temperature to come within ~ 5 ⁰F of air’s wet-bulb temperature.Approximately 80% of the temperature reduction is due to evaporation of the cooling water and heat transfer to the surrounding air. WATER TREATMENT Calcium bicarbonate which is normally present in raw water, breaks down to form relatively insoluble calcium carbonate. The design variables for the cooling tower construction are usually temperature range, approach temperature and water flowrate (Panjeshahi and Ataei, 2008). The water then exits the equipment, taking heat with it . In process cooling, the temperature and flow of the liquid will depend on the need of that particular process in removing heat from the process. Cooling systems are available in many types of design and construction, each with its advantages and limitations. Water cooling is commonly used for cooling automobile internal combustion engines and power stations.
