<p>There is provided a method and apparatus for storing energy and for utilizing the stored energy. The apparatus includes a storage container (10) which holds a phase change energy storage material such as water. A plurality of coils (11) are disposed in the storage container (10) and carry a refrigerant material. At least one evaporator (14A, 14B, 14C) is connected to the coils (11). A self pumping apparatus is connected to a condensing unit (25) to the evaporator (14A, 14B, 14C) and to the coils (11) and is operated by the adiabatic conversion of refrigerant from its liquid state to a vapor plus liquide state. The self pumping apparatus thus moves the refrigerant fluid to the evaporator (14A, 14B, 14C) without the need for additional energy input. The self pumping apparatus includes a pair of tanks (A, B) each of which alternately operate as a pumper and as an accumulator during ice melting. During ice freezing, both containers (A, B) operate as accumulators.</p> |
