The liquid ring compressor (LRC) is one of the compressors suitable for the heat pumps which use water as a working fluid. LRC has several features : 1) large suction speed, 2) low discharge temperature realized by the ring liquid, 3) simple structure. However, in order to enlarge the working temperature region of such heat pumps towards lower temperature level, it is necessary to improve the volumetric efficiency of LRC, especially at a low suction pressure region. Therefore a helical liquid ring compressor (HLRC) which has helical blades has been newly designed, as one of the attempts to obtain a higher volumetric efficiency. The HLRC is able to separate a suction space from a compression space along the axis and improve the volumetric efficiency. A test running has verified that the suction/compression mechanism of the HLRC functions as expected.
