Title:
A microcapsule thermal storage medium and a thermal storage device using it
Document Type and Number:
Japanese Patent JP6247565
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a microcapsule type thermal storage material which has a thermal storage capacity, is capable of storing heat even in a relatively low temperature range of, e.g. 30-60°C and is improved in thermal storage density and a thermal storage device using the thermal storage material.SOLUTION: A microcapsule thermal storage material contains a phase change material which absorbs and dissipates latent heat in response to a temperature change and is sealed in a microcapsule, and the phase change material contains at least one imide compound selected from tetrabutylphosphonium N-(trifluoromethylsulfonyl)-N-(1-carboxyl-3-methylthiopropyl)imide and tetrabutylphosphonium N-(trifluorometylsulfonyl)-N-(1-carboxyl-4-methylthiobutyl)imide and water. A thermal storage device using the microcapsule thermal storage material is also provided.
