Introduction of Cooling Tower’s Water Consumption

Cooling tower water consumption primarily results from evaporation, blow-down, splash, and drift losses. Evaporation alone accounts for 55-85% of total consumption and can exceed 80% in continuous-operation plants. Here's a closer look at the factors influencing water consumption:

Evaporation Losses

  • Function: Water evaporates as it removes heat from the cooling circuit.
  • Impact: Indicates the cooling tower's efficiency and the equipment's heat load.

Splash and Drift Losses

  • Process Occurs when water droplets are carried away by wind or fall back into the cooling tower intake louver.
  • Influencing Factors
    • Design of water baffles
    • Condition of water distribution tubes and nozzles
    • Maintenance status of the fills
    • Appropriateness of circulation motor size

Comparison of Cooling Tower’s Splash and Drift Losses

Some cooling towers use fans that are mismatched to their capacity, leading to increased energy and water consumption without improving cooling efficiency. Linkcooling cooling towers focus on addressing these issues to minimize splash losses effectively.

Water-Saving Design of The Linkcooling Cooling Tower

Linkcooling has implemented several design improvements to enhance cooling capacity and reduce splash losses:

Cooling Water Distribution System

  • Design Positioned above the cooling tower for even spray distribution.
  • Patented Feature The L-type water cover quickly expels hot air and prevents large droplets from being carried out by the fan, aiding in water conservation.

Inclined Water Baffle

  • Replacement: Traditional bottom intake louver replaced with an inclined water-holding baffle.
  • Benefits:
    • Reduces splash and drift losses
    • Prevents environmental damage
    • Conserves water and energy
    • Optimizes space usage

Suitable Fan and Motor

  • Importance: Selecting a fan and motor that match the cooling tower’s capacity is crucial for efficient operation and water savings.

Benefits of Linkcooling’s Water-Saving Design

  • Reduced Water Loss: Through efficient distribution and innovative design features.
  • Energy Efficiency: Optimized fan and motor reduce energy consumption.
  • Maintenance Efficiency: Reduced limescale and damage to distribution components.
