The glass window is used as an important component of a building structure and accounts for 20-40% of the energy consumption of the building envelope. The glass window has the advantages of enhancing the heat preservation and insulation performance of the glass window and improving the thermal performance of the glass window, and is one of the key means for reducing the energy consumption of buildings.
In recent years, the application of the phase-change material energy storage technology to building envelope structures becomes an important direction for reducing building energy consumption and improving indoor thermal comfort. In the daytime, the phase change material absorbs solar heat, and in the nighttime, releases the stored heat to the room. For example: the phase-change material is combined with the hollow glass window, the phase-change material is filled in the space between the two layers of glass plates, and the thermal inertia of the glass window is increased so as to improve the thermal performance of the glass window.
Although the phase-change glass window has the phase-change heat storage function, the heat release process of the phase-change material is bidirectional, so that the energy is transmitted indoors and released outdoors, and the stored heat is lost. Secondly, most phase change materials have low thermal conductivity, and the phase change materials have too long heat storage and release time. In addition, the glass window having the ventilation function has a single function, and air supplied into a room is not treated, thereby improving the air quality of the room but increasing the indoor load.
