ABSTRACT:
A selective extraction heat storage assembly (32) for use in a system including a plurality of such assemblies (32a-c) and for use by itself, includes a heat unit (10) connected in parallel with a fluid circulating passage (54) and has a separate unit heat extractor (exchanger) (34) mounted in the unit (10). The unit (10) can be charged and discharged by fluid flow through the unit caused by an outside fluid circuit and can be similarly discharged thereby. However, in addition, the unit can be charged and discharged by means of the separate unit heat extractor (exchanger) (34) within the unit by closing off the heat storage assembly from the outside fluid circuit and circulating fluid through the unit via the parallel fluid circulating passage (54). A pump (42), several sensors (46 and 52), and valves (44 and 60) form a part of the heat storage assembly to provide for this operation. When several of these assemblies (32) are connected in parallel, they can each be independently isolated from the system and their respective units charged and discharged without affecting the other assemblies and their heat units.
