400TR Round Type Cooling tower Induced draft Counter flow cooling tower

தயாரிப்பு விளக்கம்

A 400TR round, induced-draft, counter-flow cooling tower is a heat exchanger that cools water by evaporation, with hot water flowing down through fill media while air flows upwards, induced by a fan at the top, maximizing heat transfer. 

Here's a more detailed description:

Key Features:

• Cooling Capacity: 400 Tons of Refrigeration (TR). 
• Type: Round, induced draft, counter-flow. 
• Design:
• Counter-flow: Hot water flows downwards, and air flows upwards, maximizing contact and heat transfer. 
• Induced Draft: A fan at the top of the tower draws air upwards, creating the draft. 
• Function:
• Hot water is distributed over fill media (e.g., PVC). 
• As water flows down, it comes into contact with upward-flowing air. 
• Some water evaporates, cooling the remaining water. 
• The cooled water collects in a basin at the bottom. 
• The air, now saturated with water vapor, is exhausted from the top of the tower. 
• Materials: Often constructed from Fiberglass Reinforced Plastic (FRP) for corrosion resistance and durability. 
• Applications: Industrial applications, power plants, chemical plants, oil refineries, and building cooling. 
• Components:
• Fill Media: PVC or other materials to maximize surface area for heat transfer. 
• Distribution System: Sprinklers or nozzles to distribute water evenly. 
• Fan: Axial fan located at the top of the tower. 
• Drift Eliminators: To prevent water droplets from being carried out of the tower. 
• Basin: To collect the cooled water. 
• Casing/Shell: Encloses the tower structure
