EVAPORATIVE COOLING:

An evaporative cooler is a device used to cools air through evaporates on of water, Its also called as swamp cooler, desert cooler and wet air cooler. Evaporation cooling differs from typical air conditioning systems, which use vapour compression or absorption refrigeration cycles.
For evaporating cooling the cooling potential is dependent on the wet _bulb depression, the difference between dry-bulb temperature and wet-bulb temperature. It can reduce energy consumption and total equipment for conditioning as an alternative to compressor based cooling, in arid climates.

Wet bulb-> Twb adiabatic saturation temperature

Dry bulb temperature is used to determine the state of humid air.

Dry bulb-> Tdb air temperature

The knowledge of dry bulb, wet bulb or dew point of only two is enough to determine the state of moist air including the content of water vapour and sensible and latent energy in the air.

APPLICATION OF COOLING TOWER

Cooling tower is a heat exchange device that removes waste heat from a process system fluid, usually water. Industrial cooling towers are extensively used in various applications such as are listed below:

• Cooling the circulating water used in oil refineries, petrochemical and other chemical plants.
• Refrigeration and chilling plan
• Natural gas engine
• Cold storage
• Vacuum pumps
• Die casting machine
• In HAVC system cooling tower is used to dispose of unwanted heat from chillers.
• Air conditioner
• Electrical power generation plants
• Induction heating steel furnace
• Inducting melting steel furnace
• Milk and dairy plants
• Bio gas plants & renewable energy power plant
• Hydraulic and industrial oil cooler
• Dry cleaning machines

TYPES OF COOLING TOWER

The cooling tower may be classified into two types based on the circulating of air through the tower. They are

• Natural draft cooling tower
• Mechanical draft cooling tower

NATURAL DRAFT COOLING TOWER:

Natural draft cooling tower are essentially used in large power plant industries. It is a heavy duty cooling tower built to meet your most extreme power generation requirement with minimum operating cost to meet your cooling needs.Natural draft operates on the stack effects it uses their hyperbolic (exaggerate things as being way bigger deals) the shape to drive moist air out and pull the cold air in. Natural draft cooling towers does not having fans, this type of cooling tower are mostly used in electrical energy power plants and also in other industrial object such towers allow the cooling of high water volumes and are designed in both concrete and metal structures.

ADVANTAGE:

• Power saving(no power consumption to induce all flow)
• No energy consumption for fan operation
• Low cost of maintance and spare parts
• Environmental friendly
• No mechanical noise because tower without fans
• Long life of tower it payback period from 8 to 15 years
• Safety of operation

DISADVANTAGE:

• It requires a large surface areas it could cause difficulties
• High investment cost

MECANICAL DRAFT COOLING TOWER:

Mechanical draft cooling tower are essentially used in power plant industries. It used power-driven fan motors to force air through the tower.

• Induced draft
• Forced draft
• Fan assisted natural draft

INDUCED DRAFT:

A mechanical draft cooling tower with a fan at the top which pulls up air through the tower. Induced draft tower fan induces moist hot air from the tower and pull it out. This produces low entering and high exiting air velocities, reducing the possibility recirculation in which discharged air flow back into the air.

FORCED DRAFT:

A mechanical draft cooling tower with blower type fan at the intake is a forced draft model air force through by the fan into the tower. Which creates a high entering and low exiting air velocity.

FAN ASSISTED NATURAL DRAFT:

It is a hybrid type of natural draft cooling tower but it has fan which assisted air flow through the tower, in natural draft cooling tower it does not having a fan.

FRP COOLING TOWER:

We frabricate the FRP is tower in industries with high quality and best industrial standard. FRP is a smaller type cooling tower using fibre reinforced plastic material with high quality standard. FRP is known for its high corrosion resistance( how well a metal can withstand damage caused by oxidization or other chemical reactions.

FEATURES OF FRP COOLING TOWER:

• FRP are light in weight so convenient for roof installation.
• Energy efficient
• Excellent functionality
• Specific design for application.
