SYSTEM FOR SUPPLYING HOT WATER USING SOLAR ENEGY

摘要

The present invention relates to a solar hot water system capable of operating in a stable system by having an automatic supplement function of a heating medium. The solar hot water system comprises: a solar collector (100); a heating medium circulation pipe (200) to form a close circuit wherein a heating medium is circulated by connecting an inlet and an outlet of the solar collector (100); and a storage tank (300) equipped to allow a part of the heating medium circulation pipe (200) to pass around inside, and to exchange heat between hot water accommodated inside and the heating medium heated by solar heat. The heating medium circulation pipe (200) includes: a heat collection circulation pump (210) to press the heating medium in order to be circulated; and a steam-water separator (220) equipped in an inlet of the heat collection circulation pump (210) having a water level sensor (221) to sense a water level of the heating medium, and an air vent (222) to separate and discharge air contained in the heating medium. In a heating medium tank (230), a heating medium supplement pipe (240) is branched on one side of the heating medium circulation pipe (200) and connected. In the heating medium supplement pipe (240), a booster pump (250) to press the heating medium stored in the heating medium tank (230) toward the heating medium circulation pipe (200), and a check valve (260) equipped in an outlet of a booster pump (250) to prevent the heating medium from back flowing towards the heating medium tank (230) are equipped. Moreover, comprised is a control part (600) to control for controlling booster pump (250) to be operated when the water level of the heating medium is low based on a water level of the heating medium sensed by the water level sensor (221).
