The absorptive chiller processing has been used for many years but will it become the solution for cooling in the future?
Every Summer we hear brownout or black out warnings from our power companies durring peak energy usage but can some simple technology with little or no moving parts reduce our dependency on large amounts of electricity to cool our homes, businesses and schools?
Proving the point for over 15 years are a group of fishermen in the village of Maruata on the western coast of Mexico that use the suns heat to generate enough ice for storage of their fish. A total of 7 ice makers produce a half ton of ice every day without the need of electricity or coolant compressors.
With metal sheet collectors some metal tubing and coolant made from water and either lithium bromide or ammonia the hot sun heats the coolant into a gas which then compresses the coolant fluid that runs into a ice maker. As the coolant expands it cools water that makes the ice.
This same method of getting cold out of a Gas is found in common window air conditioners but because of size concerns an electric compressor is used to compress the coolant into a liquid. By removing the compressor you need a larger heating surface placed on a roof or on the side of the building.
Is this method a great solution for everyone? Maybe not now for small homes because the products are just not available but with future development it would be easy to see a small cooling panel placed along side your PV electric and Solar Hot Water panels on your roof.
However for commercial applications this is a great way to reduce your electricity costs for cooling as much as 50% or more.
If you would be interested in buying one for your home you will need a decent amount of roof or lot area for the solar collectors. This space should be reduced with further innovation but for now if you want more information contact.
