The purpose of this project is to investigate the applicability to naval ships of recent developments in absorption air conditioning using fluorocarbon refrigerants and organic absorbents as the working fluids. The investigation will review the work in the fluorocarbon absorption field during the last 20 years world wide. The many combinations of fluorocarbon refrigerants and organic absorbents are to be evaluated, as are the various absorption cycles, judging them for usability and possible advantages on naval vessels. If further advances or improvements are found to be needed to meet naval requirements attempts will be made to devise directions to be followed in future research and development. The probabilities of success in those efforts will be estimated.
