Indirect evaporative Cooler also works on principle of Evaporative air cooling but it uses an heat exchanger in primary stage. In contrast to direct evaporative cooling the water and ambient air flows in different channels .The water and hot air does not come in direct contact with each other and that is why it is called indirect evaporative cooler.
The indirect evaporative cooler cools the incoming hot air by sensible heat exchanging method. Its efficiency depends on difference between Dry bulb and wet bulb temperature. Better wet bulb depression ( DBT-WBT) and better cooling efficiency.
The air coming out of heat exchanger is dry ,as it does not get mixed with water. This dry cooled air can be best used for cooling Electric panel rooms, data centres and server rooms. it can be advantageously used in manufacturing industries where the product being manufactured is hygroscopic or susceptible to moist air .
Advantages of indirect Evaporative cooler:
- Better Cooling than Direct Evaporative Cooling
- 80% more Energy Efficient than air conditioner
- Consumes less water than Direct Evaporative Cooling
- Environmental friendly , CFC free cooling
- Dry Cooling – No free moisture particles added to incoming stream in IEC stage.
