Advantages of evaporative cooling

A comfortable work environment

A work environment that is too hot will lead to unhappy employees who will find it hard to concentrate and be productive. Research from UC Berkeley - "The impact of ventilation on productivity" - has shown that productivity drops by about 2% for every degree above 22 ℃. Oxycom's unique two-stage evaporative cooling system, IntrCooll, can cool the air down up to 20 ℃ below the outside temperature, accommodating the room, hall or building with a comfortable and productive environment. 

Environmentally friendly 

Evaporative cooling is the most environmentally friendly cooling technique on the planet. A significant advantage of evaporative cooling is that it makes use of water as its refrigerant. Thus, no harmful refrigerants are used that could affect the ozone layer.

Because two-stage evaporative cooling uses very little electricity, the system has a very low carbon footprint. Oxycom's IntrCooll already meets, or better said outperforms the goals set by the Paris Agreement requirements for cooling installations in 2050. The GWP (Global Warming Potential) of the IntrCooll is virtually 0. 

Evaporative cooler vs air conditioner

An evaporative cooler is much more energy-efficient than a traditional air conditioner. The EER of the IntrCooll goes up to 40, whereas the EER of a conventional air conditioner is a factor 10 lower. Furthermore, air conditioners drastically drop their performance from 25 ℃ onwards if ventilation is added; as a result, the COP will substantially reduce. As a result, energy consumption drastically increases to provide the desired temperature. As seen above, an evaporative cooler will only increase its cooling capacity when temperatures rise, without increasing the energy consumption. 

The graphic shows an example of the dramatic differences between the EER of an IntrCooll two-stage evaporative cooler vs a direct evaporative cooler. The higher the outdoor air temperature the greater the difference between the EER of a two-stage evaporative cooler and a direct evaporative cooler.
