Abstract
A heat storage unit includes: a heat storage material that contains water and high polymers that exhibit hydrophilicity or hydrophobicity depending on a temperature; a heat exchanger that causes heat exchange to be performed between a heating fluid and the heat storage material to heat the heat storage material and store heat in the heat storage material, and causes heat exchange to be performed between a heat utilization fluid and the heat storage material to receive heat from the heat storage material and cause heat to be transferred from the heat storage material; and a container that is filled with the heat storage material and houses the heat exchanger.
