A cold storage container has chambers of a solidifiable liquid such as water immersed in a brine. The brine is circulated to heat exchange systems which can cool the brine to below the solidification temperature of the liquid and can extract heat from a space to cool the space. The chambers are preferably formed in sausage-shaped interconnected chambers which are free to move within the container and which occupy about 70% of the container volume.
