AMMONIA CENTRIFUGAL HEAT PUMP

摘要

A heat pump, suitable for use with ammonia as a working fluid and water as an absorbent fluid, comprises a centrifuge arranged to dissolve the working fluid in the absorbent fluid, and to pressurise the resultant solution; a heat recovery unit adapted to recover heat from the solution; means for evaporating the working fluid from the solution; and an energy recovery unit adapted to recover energy such as hydraulic energy from the solution.
