What should be considered when purchasing a closed-circuit cooling tower during the hot summer weather?
When selecting a closed-circuit cooling tower during the summer's high temperatures, pay special attention to the following points to ensure the equipment's efficient operation and reliability in extreme environments:
When selecting a closed-circuit cooling tower during hot summer weather, pay special attention to the following points to ensure efficient operation and reliability of the equipment in extreme environments:
1. Heat dissipation efficiency and design margin
High-temperature adaptability : Select a model with stronger heat dissipation capacity to ensure that the cooling tower can still meet the design cooling requirements under extreme high temperatures.
Design margin : It is recommended to increase the capacity margin by 10%-20% to cope with sudden high loads or sudden temperature increases in summer.
Wet-bulb temperature parameters : Model selection should be based on the highest wet-bulb temperature in the local summer (wet-bulb temperature directly affects evaporative cooling efficiency) to avoid insufficient heat dissipation due to parameter mismatch. 
2. Material and weather resistance
High-temperature resistant materials : Prioritize stainless steel (such as 304/316), galvanized aluminum sheets, or corrosion-resistant coatings to prevent high temperatures from accelerating equipment aging.
Anti-ultraviolet design : The shell and filler must have UV resistance to prevent embrittlement or deformation caused by long-term exposure to the sun.
Anti-scaling design : Choose anti-scaling coatings or high-efficiency coil structures to reduce the risk of water scaling due to hard water at high temperatures.
3. Spray system optimization
Spray coverage : Under high temperatures, it is necessary to enhance the uniformity of spraying to ensure that the coil surface is fully wetted, improving the evaporative cooling effect.
Spray water flow adjustment : Equip with a variable frequency water pump or an intelligent control system to adjust the spray water volume according to the real-time temperature, balancing heat dissipation and water conservation needs.
Anti-clogging design : The nozzle should have a self-cleaning function or an easy-to-disassemble structure to prevent the accumulation and blockage of impurities in high-temperature environments.
4. Intelligent control and energy saving
Variable frequency technology : Use variable frequency fans and circulating water pumps to dynamically adjust the speed according to the load, reducing energy consumption during the high-temperature season.
Temperature control linkage : Integrate temperature sensors and an automated control system to adjust operating parameters (such as fan start/stop, spray frequency) in real time.
Energy consumption ratio (COP) : Pay attention to the energy efficiency ratio of the equipment under high-temperature operating conditions, and prioritize low-energy-consumption models.
5. Maintenance and dust prevention design
Easy maintenance structure : Choose a modular design or quickly detachable panels for easy cleaning and maintenance during the high-temperature season.
Dust filter device : High-temperature and dry weather easily produces dust, so it is necessary to configure an air filter or dust net to prevent dust accumulation on the coil surface from affecting heat dissipation.
Anti-algae and sterilization measures : Equip with a UV water sterilizer or an automatic dosing system to inhibit the growth of microorganisms in the circulating water at high temperatures.
6. Enhanced environmental adaptability
Wind and earthquake resistance : Summer may be accompanied by strong winds or thunderstorms, so it is necessary to confirm that the equipment structure strength meets local meteorological conditions.
Explosion-proof requirements : If used in special environments such as chemical industry and power generation, explosion-proof motors and electrical components should be selected.
Noise control : The equipment may operate at high loads during the high-temperature season. Select low-noise fans or install silencers to avoid disturbing residents.
7. Water treatment and water-saving design
Water quality compatibility : Select suitable coil materials (such as copper pipes and stainless steel pipes) according to the local water quality to prevent high temperatures from accelerating corrosion.
Water-saving technology : Use a closed-circuit system + spray water recovery system to reduce water evaporation loss at high temperatures.
Automatic sewage discharge : Configure an automatic drain valve to discharge concentrated wastewater in time to maintain water quality stability.
8. Suppliers and after-sales service
High-temperature case verification : Require suppliers to provide successful application cases and performance data in similar high-temperature environments.
Quick response guarantee : Ensure that the supplier can provide 24-hour emergency service in summer to avoid the risk of downtime.
Warranty terms : Clearly define the warranty scope under high-temperature operating conditions, such as the warranty period for core components such as motors and coils.
