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