Refrigerating agent using ice and vessel containing the refrigerating agent

摘要

The invention concerns a refrigerating agent using ice, characterised in that: at least in the range of temperature normally used between -40 DEG and +40 DEG C, the refrigerating agent (2) is a solid body (2), and said solid is made of a material with high thermal conductivity capable of accumulating frigories and restoring them quickly.
