Document Type and Number:
WIPO Patent Application WO/2017/217390
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide: a molten salt-type heat medium which has a high heat resistance temperature and is usable in a wide temperature range; a method for using a molten salt-type heat medium; and a solar heat utilization system which uses a molten salt-type heat medium.
[Solution] A molten salt-type heat medium according to the present invention comprises a carbonate mixture that contains from 10 mol% to 30 mol% (inclusive) of potassium carbonate, from 13 mol% to 35 mol% (inclusive) of sodium carbonate, from 20 mol% to 40 mol% (inclusive) of lithium carbonate, from 1.5 mol% to 15 mol% (inclusive) of calcium carbonate, from 5 mol% to 20 mol% (inclusive) of barium carbonate, and from 0.2 mol% to 35 mol% (inclusive) of magnesium carbonate and/or cesium carbonate in total.
