SOLAR HEAT UTILIZATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a solar heat utilization system which enables solar heat utilization of different temperature levels while efficiently cooling a solar cell.SOLUTION: A solar heat utilization system includes: a circulation path in which a heating medium circulates; a solar energy collector connected to the circulation path and for heating the heating medium by utilizing the heat acquired from a solar cell; a thermal stratification type hot water storage tank which stores water for exchanging heat with the heating medium and in which a plurality of thermal stratification parts in which temperature ranges of storage water are different from each other are formed inside; and a heat exchange device connected to the circulation path and for heating the storage water by allowing heat exchange between the heating medium heated in the solar energy collector and the storage water. The heat exchange device allows the heating medium after exchanging heat with the storage water stored in the thermal stratification part in which the temperature range is relatively high temperature to exchange heat with the storage water stored in the thermal stratification part in which the temperature range is relatively low temperature.SELECTED DRAWING: Figure 1
