Description: An evaluation has been made of two different techniques which could prove valuable for      Naval refrigeration needs in the future. The first is electrohydrodynamic (EHD)      enhancement of pool boiling and condensation heat transfer; this has been shown to      provide significant enhancements for both modes of heat transfer under certain conditions      and could provide increases in efficiency of present vapor-compression systems. EHD      techniques are quite advanced and prototype condenser and evaporator bundles are      currently being tested. The second technique is an alternative refrigeration technology      called thermoacoustic refrigeration; alternative technologies have become increasingly      attractive over recent years due to environmental concerns over CFCs. Thermoacoustic      refrigeration uses acoustic power to pump heat from a low temperature source to a high      temperature sink. It is still in the early stages of development and can presently      accommodate only small thermal loads. However, its general principles of operation have      been proven and its resent capacity and efficiency limitations are not seen as a problem in      the long term.
