Day time: the solar heat collector 2 extends out, the liquid in the solar heat collector absorbs solar energy for heating, and flows into the heat exchanger 7 to heat the liquid in the water inlet pipe 01, the water outlet pipe 02 and the heat exchange pipe 3, so that the problem of heating the interior of the house 1 is solved. Meanwhile, the redundant heat energy heats the heat storage capsule 503 in the heat storage box 502, so that the phase change material in the heat storage box is changed in phase, and the heat energy is stored.
At night: the solar collector 2 cannot collect solar energy and retracts inside the insulating roof 103. The solar energy liquid outlet pipe 03 and the liquid in the solar energy liquid return pipe can be prevented from dust, and heat energy loss can be avoided when the liquid flows through the solar heat collector 2. At this time, the liquid flowing into the storage box 502 absorbs the heat energy of the heat storage capsule 503, the temperature rises, and then the liquid flows into the heat exchanger 7 to heat the liquid flowing through the heat exchange pipe 3, so that the function of heating the inside of the house 1 at night is realized.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
