Eco-friendly design uses water to cool air, in lieu of Freon or other cooling agents.
Inside of the portable air conditioner is the chemical refrigerant Freon, which is drawn through a mechanical device known as a compressor.
The compressor pressurizes the Freon gas and causes it to become extremely hot.
It is then taken into a series of coils, where the heat dissipates and the Freon cools into a liquid.
As the heat dissipates, the Freon is drawn into the expansion coil.
