The present invention concerns a cooling device and method of forming and regenerating same for use in keeping perishable products cool. The cooling device includes a porous substrate that has been soaked in a first composition including at least one anti-freeze agent before being soaked in a second composition including at least one crosslinking agent and be exposed to UV irradiation. The cooling device further includes a substrate cover for sealingly covering the porous substrate after being soaked in the second composition and exposed to the UV irradiation. Prior to use, the cooling device is cooled to a desired temperature and exposed to further UV irradiation.

Antifreezes are provided for deployment in wet sprinkler systems located in cold environments. The antifreezes allow for the wet sprinkler system to be actuated under temperatures below 32° F. Wet sprinklers, sprinkler systems, methods of providing for the control, suppression and/or extinguishment of a fire that occur in a cold environment, and methods of preventing wet sprinklers from freezing also are provided. The sprinklers, sprinkler systems and methods can be used in residential, commercial and storage settings.
