The National Renewable Energy Laboratory was recently tasked to design and build a prototype DEVAP AC for testing at NREL’s Advanced Heating, Ventilation, and Air-Conditioning (HVAC) Systems Laboratory. The results showed 80% and 40% source energy savings in a typical office building in Phoenix and Houston, respectively, compared to a high-efficiency vapor compression AC.
