<p>PROBLEM TO BE SOLVED: To provide a heat pump system in which solar light utilization efficiency is increased.SOLUTION: A composite heat pump system includes: a high temperature heat circuit which is a path for a high temperature heat medium to circulate; a thermal storage medium tank which receives heat from the high temperature heat medium and in which a chemical thermal storage medium, which is a hydroxide or a hydrate, is stored; a water tank which is arranged in an outer space and in which water discharged from the chemical thermal storage medium is stored; a medium temperature heat circuit having a normal step heat circuit which is a path in which a medium temperature heat medium for receiving heat from the chemical thermal storage medium circulates, in which the hydroxide or the hydrate receives heat from the high temperature heat medium and which is a recovery path of steam condensation latent heat accompanying a dehydration reaction for deviating water, and a reverse step heat circuit which receives heat from the outer space, and which is a recovery circuit of the hydration heat accompanying a hydration reaction between vaporized water and the dehydrated hydroxide or the hydrate; a first flow rate control unit for controlling a heat medium flow rate into the normal step heat circuit; and a second flow rate control unit for controlling the heat medium flow rate into the reverse step heat circuit.</p> |
