In Two Stage Evaporative Cooling system ,the first stage is  Indirect Evaporative cooling .In Indirect Evaporative stage  (IEC) the water and hot air travels in different channels .Water and hot air doesn’t come in direct contact with each other and that is why it is called Indirect Evaporative cooling system. Dual stage system is also called Indirect Direct Evaporative Cooling  system .It additionally uses a heat exchanger called DAMA. The DAMA heat exchanger is a cross-flow, plate-type polymeric exchanger. Warm, primary air flows in enclosed channels and gives up its heat to water films flowing down the other side of the polymeric plates. A secondary air stream flowing in the direction opposite to the water, evaporates water before it is exhausted outside. Thus, the primary air is cooled without any moisture addition. In Two stage  Evaporative cooling  no free moisture added to the incoming air and because of  this fact sometimes called  dry evaporative cooling.Two stage Evaporative coolers  are also known as Indirect Direct Evaporative Cooler. Evapoler has used this two stage evaporative system   in replacement of air conditioner for comfort cooling large  industrial  spaces where air conditioning is not feasible .All food processing applications ,Industrial Kitchens  where positive pressure is a  concern and need large volume of cool & fresh air  Indirect Direct Evaporative cooling system is the best  Cooling option.


  • IDECool 4

    Refrigerant based air-conditioning entails higher capex and opex, while conventional evaporative cooling solutions fall short of delivering the desired level of cooling and comfort especially during rainy weather. IDEcOOl4 is energy-efficient and eco-friendly Two stage cooling solutions, based on innovative & patented indirect evaporative cooling technology, a truly “Make in India “ Product.

  • IDECool 6

    The IDEcool6 is a next-generation two-stage evaporative cooling Equipment. It uses a unique ,energy efficient two stage process to cool air. Indirect Evaporative Cooling (sensible cooling – no moisture addition), followed by Direct Evaporative Cooling (adiabatic cooling). This enables the IDEcOOL to deliver cool air at sufficiently reduced dry Bulb temperature and low moisture level. It is an excellent upgrade over conventional air washers . The IDeCOOL is also an energy-efficient and natural air conditioning alternative to conventional air conditioners

A.How Does Two  Stage Evaporative Cooling  System Work?

2- stage evaporative cooling system also called Indirect Direct Evaporative cooling  represents the most advanced cooling system – utilizing evaporative cooling technology. This cooling option is much more energy efficient than cooling with refrigerant (standard air conditioning), but it’s most suitable for large open and semi open spaces or where sufficient ventilation provisions are available.

 

The working principle of  2-stage evaporative cooling in terms of the stages of cooling is based on Evaporative cooling technology . In the first stage, hot outside air and water  passes inside a heat exchanger in different channels . Moreover ,During this initial cooling phase, the incoming air stream doesn’t pick up any extra moisture. In the second stage of two stage Evaporative Cooling system , the same air stream passes through a water-soaked pad where the additional cooling takes place and the air picks up some additional moisture.

A two-stage evaporative cooling system can deliver cool indoor air with Low relative humidity compared to  direct evaporative cooling systems  which typically  deliver the air at around 70%-80% relative humidity.

According to the American Society of Heating and Engineers (ASHRAE), two-stage evaporative coolers  use 60%-75% less electricity than conventional refrigerant-based AC systems. Therefore, evaporative cooling is a very attractive option in terms of energy efficiency.However it is important to note that these systems are best-suited for the hot, dry climate found in India.

 

B. Advantages Of The Two-Stage Or  Indirect Direct Evaporative Cooling System

  • This technology helps in reducing the running cost by  consuming less electricity  .Further Indirect Evaporative cooling  is used where dry air or low  humidity supply  air is needed.
  • It is Energy Efficient and cost-effective Solution .Indirect Evaporative  Cooler  consumes almost  half the energy required by an air conditioner .Moreover  ,the Capex  is also relatively  low.
  • Two-stage evaporative cooling systems helps in cooling the conditioning space with  100% fresh air .These  are designed for 25-35  ACPH for better cooling and adequate ventilation.
  • It is an eco-friendly cooling system as no harmful refrigerants are used .
  • Evapoler uses  only premium quality  Patented Heat Exchangers  from HMX . The Centrifugal Blowers from Nicotra / Krugger  .The Electric motor used  are  IP 55 Protected with IE2 /IE3 efficiency .The standard make Motors of Siemens / ABB /CG /Havells  are used.
