Direct contact cold heat extraction from water mixture of gel type air latent heat storage material to air bubbles

摘要

This paper has dealt with cold heat extraction characteristics from the gel latent-cold-heat storage-material suspensions with surfactant to air bubble. The gel latent-cold-heat storage-material consisted of n-paraffin as the core latent-cold-heat storage-material. The relationship between output air temperature in latent-cold-heat release process and the various parameters were examined. As a result, especially concentration of gel latent material added to water had great influence on gas holdup and cold extraction characteristics to air bubble.
