Taking the example that the water inlet pipe is communicated with a municipal pipe network and the water outlet of the heater is communicated with a domestic hot water pipe, in the heat-preservation and heat-storage circulating system, water conveyed from the municipal pipe network passes through the heat-preservation water tank and then is conveyed to a circulating water flow layer of the heat-preservation and heat-storage window by the circulating water pump, the circulating water preheats the circulating water at the glass window through solar radiation, and then the preheated circulating water returns to the heat-preservation water tank through the connecting pipe. The preheated circulating water exchanges heat with the phase-change material of the inner phase-change layer in the heat-preservation water tank fully, and the circulating water is heated by the gas/electric heater from the water outlet pipe of the heat-preservation water tank and then is conveyed to a heat user.

The glass is applied to the outer window of the building glass, and the water flow layer and the phase change material layer are added in the glass, so that the heat preservation and heat storage effects are realized. The phase change material layer and the water flow layer are added in the three-layer glass window, so that the solar heat storage window has positive effects of reducing heat exchange loss inside and outside the window in cold regions and improving solar heat storage efficiency.
