Perhaps one of the most amazing technologies that you have seen over and over for years but never realized it even existed. These chillers use heat to cool. Think about the refrigerators and freezers you have seen in RVs – there you go, adsorption chillers. Only think bigger, in some instances much, much bigger. It may not make sense to you at first that the sun’s energy that is making a summer day so uncomfortably hot can be used to cool your building, but that is exactly what this technology does. With the technology that is now available to power these systems with solar energy, absorption chillers are creating a revolution in space cooling and materials handling. The technology has been around for decades and by combining it with new solar power innovations these systems are positioned to change the very definition of what air conditioning can do.
