ABSTRACT:
A latent heat-storage device for cooling purposes includes a non-deformable closed container, and a heat-storage medium comprising water or a eutectic aqueous solution of a salt contained in the container. The heat-storage medium expands in volume as its temperature is lowered through its phase transition from fluid to solid. The amount of the heat-storage medium is such that a part of the container volume equals or is slightly larger than the maximum volume expansion of the heat-storage medium during operation of the device. A gas condensing between room temperature and the melting temperature of the heat-storage medium fills the container part at atmospheric pressure and room temperature.
