A lubricant-free sonic compressor has been developed in the USA. The operation relies on an oscillation created by a mechanism similar to a loudspeaker. A high-amplitude standing wave is created in a resonator cavity which compresses a refrigerant. This device takes the place of the compressor in a traditional vapour-compression circuit, only as no lubricant is needed, the refrigerant can be chosen without oil compatibility. A prototype domestic refrigerator should be working during 1993. D.W.H.
