James, T W

A holdover plate is described for thermal energy storage in refrigeration and air conditioning systems, the holdover plate comprising: a heat exchanger with an adjacent space in close proximity thereto; a plurality of expandable capsules containing a thermal energy storage medium, the capsules substantially filling the adjacent space and the capsules including means to provide for expansion of the thermal energy storage medium without altering outer envelope dimensions of the capsules; a containment means forming an exterior of the holdover plate and surrounding the heat exchanger and the adjacent space filled with the capsules, the containment means further containing a convective coupling fluid which thermally couples and is non-corrosive to the heat exchanger, the capsules, and the containment means; and wherein the convective coupling fluid transfers heat primarily through natural convection and conduction and does not freeze at operational temperatures of the heat exchanger.
