What are the advantages of cooling towers after energy-saving transformation?

　　The birth of the closed cooling tower originated from the industrial transpiration cooler, which is a kind of name relative to the open cooling tower. As a direct touch cooling tower, the filler of the ordinary open cooling tower is heated by the heat exchange plate. Tube group replacement, and the service target can be widely used from common cooling with low requirements to high cleanliness of the process fluid and high precision of the process fluid temperature control. So, what are the advantages of closed-circuit cooling towers? Now let the closed-circuit cooling tower manufacturer China trlon energy-saving air conditioners summarize:pjJCooling tower noise reduction treatment manufacturer

　　Strength 1: Less water consumption and energy savingpjJCooling tower noise reduction treatment manufacturer

　　The main feature of a closed cooling tower is the use of cooling coils to separate the process fluid from the air flow. In an open cooling tower, the heat and mass transfer processes occur directly between the water droplets or water film and the surrounding air flow. In a closed cooling tower, the heat is first transferred from the process liquid in the coil to the wall of the coil by convection and conduction, and then the water droplets or water film on the periphery of the tube wall are sprayed with the surrounding wall by means of heat and mass transfer. The air stream exchanges heat. In this system, the process fluid in the coil does not touch the outside air flow. The outer surface of the coil is kept wet by the spray system in the tower. The fan drives air through the coil. Under the same thermal load conditions, the loss of transpiration, splash loss and blowdown loss of the fluid cooling tower will be reduced to a minimum.pjJCooling tower noise reduction treatment manufacturer

　　Strength 2: The use of special process requirementspjJCooling tower noise reduction treatment manufacturer

　　For some situations, because the water source needs to be maintained from pollution, or because the environment needs to be maintained to avoid the influence of harmful components in the process fluid, the process fluid is not allowed to be directly exposed to the outside environment. In these cases, the process fluid must be isolated from the external environment and passed through some external medium for cooling. This is an important feature and advantage of closed cooling towers.pjJCooling tower noise reduction treatment manufacturer

　　Strength 3: Power-saving dry operation modepjJCooling tower noise reduction treatment manufacturer

　　The dry operation in the closed cooling tower does not use an external water source. In this form, air is used as the cooling medium, and the water (or other liquid) in the coil is cooled by the outside air flowing through the coil with fins. For every 1°C increase in temperature, only about 1.0kj of heat can be taken away per kg of air. Therefore, dry operation can only be used in cold weather or cold seasons. In dry operation, the closed cooling tower system only turns on the fan to drive the air, and the spray water pump stops running, so the energy consumption is greatly reduced, and the consumption of spray water is also relatively reduced.pjJCooling tower noise reduction treatment manufacturer

　　Strength 4: Simplified structure and reduced floor spacepjJCooling tower noise reduction treatment manufacturer

　　The most commonly used closed cooling tower is a mixed-flow structure design, in this structure, the coil is located on the top of the system for repair. The cooling tower’s heat-dissipating filler is located under the coil to allow air to flow parallel through the coil. This method will further increase the cooling efficiency of the system. Compared with the cross-flow and counter-flow closed cooling towers, the heat transfer effect of the mixed-flow closed tower is significantly increased, which reduces the floor space of the mixed-flow closed cooling tower, reduces equipment costs and energy consumption, and retains easy repair Strengths.pjJCooling tower noise reduction treatment manufacturer

　　Strength 5: Very widely usedpjJCooling tower noise reduction treatment manufacturer

　　The most common use of closed cooling towers for civil air conditioning is the water source heat pump system, and the coil part can be insulated and maintained to reduce the heat loss of the system during winter operation. Closed cooling towers are also often used in water-cooled host systems to avoid scaling of condensate water and can directly supply system water in winter. In many industrial applications, closed cooling towers can be used to cool intermediate frequency furnaces, induction cookers, air compressors, large pressure transformers, and oil cooling systems for turbines.pjJCooling tower noise reduction treatment manufacturer

　　Strength 6: Small investment costpjJCooling tower noise reduction treatment manufacturer

　　From the overall point of view, the closed cooling tower combines an open cooling tower and a heat exchanger. Transpiration cooling occurs directly on the outside of the coil, and then the process fluid in the coil is cooled. Compared with open cooling towers or transpiration coolers, the heat exchange coils of closed cooling towers are placed in the cooling tower, eliminating the "shell" of the heat exchanger. The original piping system was simplified as a water spray circulation loop from the cooling tower water tank to the coil. This greatly reduces investment costs and floor space.pjJCooling tower noise reduction treatment manufacturer

　　Strength 7: Choice of coil structure that is easy to repair and maintainpjJCooling tower noise reduction treatment manufacturer

　　In the same cooling environment, choosing different coil structures will result in different cooling effects. Taking into account the nature of the process fluid, the pH of the spray water, and the convenience of repair, the data and structure of the coil can be as follows: Different choicespjJCooling tower noise reduction treatment manufacturer

　　1. Snake-shaped galvanized steel coil. This structure is the most common type of coil in closed cooling towers, because it can use water, glycol solution and other clean and non-corrosive solutions and steam and other media, and is the lowest cost structure.pjJCooling tower noise reduction treatment manufacturer

　　2, steel pipe without joints. In this structure, a long steel pipe is bent forwards and backwards to reach the required number of channels, and then assembled into a coil control, connected to a common coil inlet/outlet interface. The assembled disc tube is galvanized by hot dip galvanizing method. In the case of severe corrosion, copper pipes and stainless steel pipes with higher costs can be used to replace ordinary steel pipes.pjJCooling tower noise reduction treatment manufacturer

　　3. Coil structure with detachable panel. In occasions that are prone to fouling or clogging, you should consider choosing a coil structure with a common inlet/outlet interface with a detachable panel, so that the inside of the coil can be easily cleaned when necessary.pjJCooling tower noise reduction treatment manufacturer
