CogniTek has an exclusive license from NASA for an absorption heat pump that provides air conditioning and medium temperature refrigeration within a system that is lightweight and small in comparison to most other absorption systems.  We are also introducing our expertise in heat exchangers and thermodynamic processes to push the performance envelope even further.

The concept of heat pumps based on absorption cycles energized by heat has been understood for years, but some of these heat pumps are outlawed in many areas because of the potential hazards posed by leakage of working fluids.  For example, in the case of the water/ammonia cycle, there are potential hazards of toxicity and flammability.  The absorption/desorption cycle of the champagne heat pump is similar to the water/ammonia cycle, but carbon dioxide is nontoxic and environmentally benign, and one can choose an alcohol or other organic liquid that is also relatively nontoxic and environmentally benign.
