ABSTRACT:
A plurality of generally rectangular PCM (phase-change material) containers for use in a TES (thermal energy storage) system wherein each container is shaped to lock-support at least one pair of superimposed adjacent containers so that each row of containers is offset from each other. In one embodiment each container is cross-sectioned in the general shape of a bow tie or an hour glass so that there is a recessed or depressed portion in the top and the bottom of the container running the full length thereof. Further, the top and bottom surface material of each container is shaped in the form of an undulating wave pattern that extends in the longitudinal direction parallel to the long axes of the aforementioned depressed portions, and the node portions of which are provided with grooves or flow channels which extend in a lateral dimension, normal to the long axes, so as to circumscribe the container. These grooves not only provide flow channels for the heat transfer fluid, but they also allow each container to expand or contract with the PCM when the latter is changing state. In another embodiment the containers are generally flat and are intended to be supportive of one another in a vertically stacked array; channels or recesses are provided in the sidewalls to allow for expansion and contraction in a vertical direction. Also provided is a conduit seal system and a liquid level control for improving the efficiency of the thermal transfer fluid used with the containers in the TES tank.
