<p>A heat pump consists of a drum-shaped, fast rotating evaporator (1) and a drum-shaped condenser (2) which is combined endwise with the evaporator drum to a drum unit having an intermediate ring chamber (6) having a larger diameter than both the evaporator drum (1) and the condenser drum (2), and being adapted to contain an annular reservoir for condensate (11). A pump wheel (12) for a liquid ring compressor extends into the condensate ring (11) and serves both as a partition to keep apart the gases (vapours) in the evaporator (1) and the condenser (2), respectively, and as a compressor in order to compress vapourous working medium from the evaporator (1) and deliver this medium to the condenser (2). The annular chamber (6) at the same time serves as a return passage for condensate from the condenser (2) into the evaporator and forms a liquid seal between the condenser and the evaporator to resist the pressure differential present, which is possible because of the rather fast rotation of the liquid pump and the resulting high specific gravity of the condensate in the liquid ring.</p> |
