Cooling towers are of various types used for different industrial applications. They play a vital role in maintaining the temperature by transferring the excess heat into the atmosphere. Cooling towers are designed into two forms, one is round-shaped and another one is square-shaped. The difference in shapes can have more impact on functionality and performance.

Bottle cooling towers

• Round or bottle-shaped cooling towers appear in hyperboloid structures works on counterflow methodology helps in withstanding high velocity and vibrations.
• The tower casing is made up of tough fiberglass which makes it corrosion-free and lightweight. A round-shaped cooling tower working with an active cross flow mechanism is not always to be in hyperboloid.
• It works in the principle of induced draft counter flow. Due to its round shape air current flows smoothly around all the surfaces preventing recirculation.
• Bottle shape cooling towers are more efficient in transferring energy and effective in allowing warmer air can withstand huge loads. It provides high durability and less maintenance. It is more cost-effective than square cooling towers

Square cooling towers

• Square cooling towers work on the principle of induced draft counter flow. It can vary in different sizes depending on the requirement of the space. Usually comes in a cuboid shape.
• It is more appealing in the buildings because of the design and appearance.
• They do not produce noise and maintenance is easier.
• It is fully corrosion resistant and weather resistant.
• Square cooling towers are quite costly but it gives more life expectancy

Water-cooled cooler

In a water or liquid-cooled cooler, the generator uses coolant to maintain the temperature. It uses a radiator and water pump. The pump distributes the cooling liquid or water into the engine blocks. The engine heat is transferred to the water.

• Water-cooled coolers are more compact than air-cooled coolers.
• The condenser used is tube-in-tube, tube-in-shell, and plate type.
• It does not require fresh air or ventilation. It can be installed indoors or outdoor. But it is exclusively designed for indoor areas.
• Water-cooled coolers are too expensive compared to air-cooled coolers, but it is more durable and powerful than air-cooled coolers.
• Water-cooled coolers work better in high-temperature environments and can be placed anywhere with minimal ventilation.

Air-cooled cooler

An air-cooled cooler uses air as a circulation medium to cool down the temperature. An air-cooled system transfers the heat to the atmosphere taken from space. Then heated air is released or expelled.

• An air-cooled cooler uses ambient air to cool the refrigerant. The condenser cools the refrigerant using the air as a coolant.
• Air-cooled coolers require ventilation to the outside. A sufficient amount of fresh air is required for the maintenance of temperature.
• These types of coolers are best for outside installations provided with environmental conditions and electricity configuration.
• It is completely portable and moved to different locations.
• It is the best choice for water conservation. It does not require water resources.

Wrapping up

Bottle cooling towers are used in large-scale projects with expandable space and demands. While square cooling towers are used by the residents & can fit any space. Regular maintenance is required. Based upon the requirements and space one can choose whether bottle cooling tower or square cooling tower that suits their industrial needs.
