Abstract

The present invention relates to a thermal accumulator for a cold/heat storage device. The present invention further relates to a method of manufacture of said thermal accumulator for a cold/heat storage device as well as the production of the associated cold/heat agent. In a first aspect of the invention a thermal accumulator is provided for a cold/heat storage device that is configured for use in a refrigerated container for cooling products that are present in the refrigerated container, the thermal accumulator comprising a compartment for containing a heat- accumulating medium, said compartment being manufactured from heat-insulated wall components and, by means of a thermal interface, for giving up cold from the heat-accumulating medium to the refrigerated container, wherein the heat- accumulating medium is a refrigerating composition comprising a salt solution that consists of a composition of at least one water-soluble salt with a percentage by weight that is between 10 and 55%, as well as water with a percentage by weight that is between 45 and 90%, and an antibacterial additive comprising bronopol.
