Harvesting free energy from the atmosphere  

The Technique


An industrial workspace is hot because of the heat radiated from the roof and walls and is hotter if there is heat generated from the work process.


If sufficient amount of outside air is cooled and sent in and at the same time exhausted out by the natural way (open doors and windows) or by a mechanical means (exhaust fan), the workspace is bound to be cool. All the heat in the workspace is carried along with the air exhausting out.

This is why evaporative cooling system will perform well especially with an exhaust system.
