A METHOD FOR USE OF LATENT HEAT TO MAINTAIN SELECTABLE COLD STORAGE TEMPERATURES

摘要

A method for maintaining selectable cold storage temperatures for protracted periods of time using pre-mixed thermal control materials having predetermined melting temperatures equal to the selectable cold storage temperatures is provided. According to preferred embodiments, the thermal control materials are solutions that are filled into cold packs 10 and the solutions are frozen to maintain selected temperatures less than 0 °C. The present invention includes methods of storage and transport of materials using the cold packs 10.
