ARPA-E seeks innovative research and development approaches to increase energy efficiency and reduce GHG emissions due to cooling of buildings in the following areas: 1) cooling systems that use refrigerants with low global warming potential; 2) energy efficient air conditioning (AC) systems for warm and humid climates with an increased coefficient of performance (COP); and 3) vapor compression AC systems for hot climates for re-circulating air loads with an increased COP. The unique challenge for the U.S. market is to develop technologies that can be retrofitted into current cooling systems. For developing economies, there is a large market for new cooling technologies. The development of these technologies will reduce GHG emissions and significantly increase U.S. technological lead in rapidly emerging clean energy industries.
