Abstract
A multiple disk compressor has a through flow of a two-phase medium consisting of gas bubbles entrained in a non-miscible liquid carrier and causes an almost isothermal compression of the gaseous phase of the medium. Because of the larger density at a given tip speed, much higher pressure ratio is obtained in a single stage than can be obtained in a conventional compressor having a throughflow of gas only. The liquid carrier, after separation from the compressed gaseous medium, provides heat to a heat exchanger before being reduced in pressure and returned to the compressor. The separated gaseous medium under pressure is withdrawn as the useful product. Where the compressor is a part of a refrigeration system and the gaseous medium is a refrigerant, the compressed gaseous medium, which is transformed to a liquid state by the compressor, flows through an expansion valve to reduce its pressure and temperature, an evaporator to cool a medium, such as air, and is returned to the compressor for re-entrainment in the liquid carrier.
