Energy storage apparatus and method

摘要: There is provided a method and apparatus for storing energy utilizing the stored energy. The includes storage container which holds phase change material such as water. A plurality of coils are disposed in carry refrigerant material. At least one evaporator connected to coils. self pumping condensing unit, coils, operated by adiabatic conversion from its liquid state vapor plus state. thus moves fluid without need additonal input. pair tanks each alternately operate pumper an accumulator during ice melting. During freezing, both containers accmulators.
