100 Year Old Technology

The history of air conditioning dates back as far as the 2nd century when Chinese inventor Ding Huan invented a rotary fan for air conditioning, it had seven wheels that were 9.8 ft in diameter and manually powered.In 1928 Thomas Midgley Jr. created the first chlorofluorocarbon (CFC) gas, Freon, in 1928.

Why is the new Technology out there?

Researchers have been trying to find an answer to the expensive use of energy it takes to cool America's homes and businesses. About 5 % of the entire energy used in the United States each year goes to running air conditioners.

What's new is the merging of evaporative cooling and desiccant drying into a cost-effective system, making this type of air conditioning viable for commercial and residential processes for cooling.

What’s new?

Why is it changing?

This is a direct answer to more efficient and energy saving system with more effective cooling system without the use of chlorofluorocarbons (CFC’s) that are harmful to the environment and natural eco-system of our planet.

What is the major breakthrough?

A desiccant used to absorb moisture from humidity and turn it to pure water using a solution of lithium chloride or calcium chloride, (about 44 percent salt by volume).

Another membrane separates the desiccant from air traveling through a channel. The polymer membrane has big enough that water vapor passes through easily while the salty liquid stays put.

• The desiccant pulls moisture from the airstream, leaving dry, warm air. • Then it's back to the current technology, called indirect evaporative cooling.• Through a second channel, water evaporates to cool a secondary airstream. • This cools the first airstream, and out comes cool, dry air.

How it works

Who does this new technology benefit?

• This new technology benefits the overall population, using up to 90 percent less energy.

• Addresses the age old humidity problem by the merging of evaporative cooling and desiccant drying into a cost-effective system.

• Tax breaks (The Emergency Economic Stabilization Act of 2008 ).

• Saving our planet by not using harmful ozone depleting chemicals (CFC’S).
