Abstract:
The present invention relates to a solar water heating system. According to the present invention, the system comprises: a heat collector which collects solar heat; a heat collector circulation pipe which is connected with the heat collector, and in which a working fluid in which the solar heat collected by the heat collector is accumulated is circulated; a heat storage system in which heat exchange occurs between the working fluid and daily-life water; a hot water circulation pipe which is communicated with the heat storage system, and from which the water is supplied; a frost protection valve which is equipped on one side of the hot water circulation pipe, and is selectively opened and closed so that the water of the heat storage system flows into the inside of the hot water circulation pipe selectively; and a controller which protects the hot water circulation pipe from frost by controlling operation of the frost protection valve according to at least one or more temperature changes of the temperature (T1) in a certain part of the hot water circulation pipe and the water temperature (T2) of the heat storage system.
