Evaporator with cool storage function

A chill water system combining a storage vessel 10, a multiplicity of ice encapsulating units 11 contained in the vessel and a chiller system 60. The storage vessel contains a volume or glycol and water solution having a freezing point of about twenty six degrees F. The ice encapsulating units 11 comprise sealed containers filled with a deionized water. The containers have imperfect geometric shape and deformable wall structures to permit an increasee in enclosed volume as said water therein freezes. Chiller system 60 is operatively associated with the vessel and cools the glycol and water solution to about twenty six degrees to freeze the water in the containers 11. A topping tank 90 and an inventory tank 93 receive liquid from the storage vessel 10 as the ice encapsulating units 11 freeze and expand in volume.

Ice building, chilled water system and method

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.
