The present invention relates to heat pump systems using water as the thermal fluid, and in particular to heat pump systems capable of producing binary ice. The heat pump system comprises a unit, a first heat exchange system, and a second heat exchange system. The unit comprises an evaporator, an axial flow compressor, and a condenser. The evaporator and the condenser are not in water communication with one another through an expansion valve. The heat pump system also comprises a) a first control system configured for adjusting the level of liquid water in the condenser to a level within a preset threshold range and/or b) a second control system configured for adjusting the level of liquid water in the evaporator to a level within a preset threshold range, and wherein the first and/or second control system comprises means for moving liquid water from the condenser into the liquid water, and below the waterline, in the evaporator |
