What is Bench Top Cooling Tower?

TTEB, or benchtop cooling tower, is basically designed for students to learn the construction, design, and working of the evaporative system. It is the compact, smaller-scale version of a full-size cooling tower. The purpose behind its creation is to show the mutual working of different parts of a cooling tower. This characteristic makes it a good tool for understanding and testing. 

This unit represents an open system in which two fluids, water and air, interact with each other.  During this interactivity, heat is transferred from one fluid to the other. This system is particularly beneficial for those who are studying in fields such as chemical/  mechanical/ mining engineering, energy transfer & conversation, building services, etc. Therefore, the benchtop cooling tower allows students to gain training and perform testing to research and develop new technologies. 

Main Components of Bench Top Cooling Tower

It is an exclusive unit that represents a complete cooling tower operation. It consists of different parts which work together to demonstrate the principles of cooling and heat transfer. The main elements of this simple-looking branch are:   

Temperature Sensors

The benchtop tower has a detector located at the top that checks the water temperature before it enters the cooling tower. This sensor takes note of how hot the water is initially. 

As the hot water flows down through the manifolds inside the tower, it starts to cool down. The manifolds allow air to pass through, taking heat away from the water. After the cooled water falls from the tower, it collects in the tank below. There is a second temperature sensor that measures the water heat again, showing how much it has cooled down. 

Pump and Water Circulation System

The pump or motor is the most essential part of any cooling system. It moves hot water from the tank to the top of the tower. The tank consists of a level switch, which maintains the water level and ensures that it never runs out of water. It also has a heating element that keeps the water warm, which will travel to the manifolds. These are the distribution pipes located at the top of the cooling system, and water then flows down through the tower. 

The important point here is whether there ar some control panels or not. Yes, there is a manual needle valve that allows users to adjust the water flow pattern, which must be supplied consistently throughout the cooling tower’s fill medium utilizing the water distribution system. Distribution basins, nozzles, and pipelines are often included. Proper distribution ensures uniform wetting of the fill material, which maximizes heat transfer efficacy.

Louvers

The tower’s outside side is encircled with louvers. These are placed to control the passage of air into the inside structure. The location of the louvers may be adjusted to control the heat exchange rate. The location will affect how much air enters the tower. This component also assists in keeping trash and foreign particles from entering the structure.

The louvers help improve the tower’s aesthetics and reduce noise during operation. Just like the water flow rate variation affects the performance of the cooling tower, airflow can also be kept in control. Louvers perform this function to improve heat exchange efficiency. 

Cooling Tower Casing

Structural components provide stability and support to the tower. These include diagonal or horizontal support beams that aid in holding the weight of the tower. The second part is the vertical pillars or columns that manage or upkeep the height of the cooling tower. The last part consists of an outer covering that protects the internal components and allows them to function correctly. 

These elements are made up of durable materials, such as stainless steel, fibreglass, and concrete wood. The compact layout is highly beneficial, allowing other components to perform their functions efficiently. They also help towers withstand weather fluctuation, movement, vibration, weight, pressure, etc. 

Drift Eliminators

These are essential cooling tower components. They catch tiny water droplets, known as drift, floating in the air as they leave the tower. These may contain pollutants or chemicals from the water passing through the tower. If they’re not caught, they can escape into the environment, causing contamination. 

These drift eliminators can conserve water and keep the environment clean by preventing pollution. Their main functions are restoring collected water to the basin, reducing drift losses and improving cooling tower efficiency. On the other hand, it is also comprised of mesh panels or baffles to capture and collect rainfall.

Air Fan

It is the most visible component, usually at the tower’s top. It is used to pull air so that the water inside the tower and the surrounding air exchange heat more efficiently.  It makes it easier for water inside and surrounding air to exchange heat by pulling the air through the tower. 

When the fan successfully spins, it creates airflow to remove heat from the system and evaporate water. First of all, this process pulls hot air out of the tower and brings the cold air, ultimately speeding up the dissipation and cooling the water.

You should consider factors while selecting the fan for your tower. These include size, shape, motor power, efficiency, durability, and tower reliability. Choosing the right fan motor will ensure optimal efficiency, performance, and longevity for your cooling tower. 

Conclusion

Knowing a cooling tower is essential as it enhances the educational experience through practical learning. It also improves the research and development of cooling technologies, ultimately increasing efficiency and productivity in industrial settings. The benchtop cooling tower will help you in this regard. In this blog, we have discussed the fundamentals of this small tower and its key elements. 

By comprehending the core concepts of Bench Top Cooling Tower components, you’ll be well-prepared to face the problems and possibilities in cooling technology, which drives innovation and efficiency across sectors.
