Heat pump for central heating - generates electric power and stores heat with pump connected in cascade with rankine circuit using water as medium

摘要

A heat pump is driven by a thermal energy for central heating, air conditioning or refrigeration plants. It generates electrical energy and stores heat, as well as retaining coldness. A number of thermally-driven heat pumps are connected in cascade with a Rankine circuit for generating electrical energy. The Rankine circuit uses water as the thermodynamic medium. The hottest heat pump in the cascade uses helium and the coldest heat pump uses ammonia.
