[0002] In China, building energy consumption accounts for more than one-third of the total energy consumption, and with the continuous development of society and economy, the proportion will further increase, so building energy saving has become a key link to realize the double carbon goal of China. The energy consumed by active temperature and humidity control equipment such as heating, refrigeration and humidity control of buildings accounts for more than half of the total building energy consumption. Improving the heat and moisture transfer performance of building envelopes can maintain the indoor heat and moisture environment at a relatively stable, comfortable and healthy level, while reducing the cooling and heating load of the building, reducing the demand for heating, refrigeration and other equipment, and achieving the purpose of energy saving and emission reduction.

[0003] In house building, windows are an essential part, and the heat and moisture exchange between the outside and the indoor is mainly concentrated on the windows. Due to the material and thickness of the window itself, the heat insulation capacity is poor, far less than that of the surrounding wall. Especially in summer and autumn, the indoor and outdoor temperature difference is large, and the heat transfer of the window is large, which greatly increases the indoor heat and moisture load.

[0004] Traditional louver windows can only hinder sunlight from shining into the house, and have single function, and cannot realize the function of saving. Developing a multifunctional window that can save energy and reduce carbon and is easy to use is one of the research hotspots in the building field. SUMMARY

[0061] In this embodiment, the transparent shell uses polycarbonate (PC) material, the phase change heat storage material uses sodium sulfate decahydrate, and the one-way dehumidification material uses polyurethane / polyacrylonitrile fiber membrane.

[0062] Method for preparing polyurethane / polyacrylonitrile fiber membrane:

[0063] Step 1, preparation of PU spinning solution: a certain mass of polyurethane (PU) particles is dissolved in N,N-dimethylformamide (DMF) and tetrahydrofuran (THF) solvents with a solvent mass ratio of 1:1, and stirred to room temperature to obtain a PU spinning solution with a mass fraction of 14%;

[0064] Step 2, preparation of PU / PAN mixed spinning solution: a certain mass of polyacrylonitrile (PAN) powder and polyurethane (PU) particles with a mass ratio of 4:1 are dissolved in N,N-dimethylformamide (DMF) to obtain a solution with a mass fraction of 12%, and stirring to obtain a PU / PAN mixed spinning solution;

[0065] Step 3, preparation of PAN spinning solution: polyacrylonitrile (PAN) is dissolved in N,N-dimethylformamide (DMF) to obtain a solution with a mass fraction of 12%, and stirring to room temperature to obtain a PAN spinning solution;

[0066] Step 4, the PU spinning solution, PU / PAN mixed spinning solution, and PAN spinning solution are respectively added to the electrospinning machine to prepare the PU hydrophobic layer, PU / PAN flow guide layer, and PAN hydrophilic layer.

[0067] The phase change heat storage and dehumidification window has four modes: ① heat storage and dehumidification mode (such as Figure 2 ), the transparent heat storage structure and the dehumidification structure are both closed, which can block a large amount of solar radiation into the room, reduce the indoor temperature, and condense the moisture in the indoor air into liquid droplets to flow out, reduce the indoor air humidity, and form liquid droplets in the gap. Sliding also takes away part of the heat in the heat storage structure, strengthening the cooling effect; ② light transmission heat storage mode (such as Figure 3 ), the transparent heat storage structure is closed, and the dehumidification structure is opened, sunlight is incident on the transparent heat storage structure, part of the heat energy is absorbed, and the other part passes through the transparent heat storage structure to provide illumination for the room; ③ light blocking dehumidification mode (such as Figure 4 ), the transparent heat storage structure is opened, and only the dehumidification structure is closed, which can block light and increase the evaporation of moisture in the dehumidification structure to lose outside, improving the dehumidification efficiency; ④ ventilation mode (such as Figure 5 ), the transparent heat storage structure and the dehumidification structure are both opened, which makes the indoor and outdoor connected for ventilation.

[0068] In order to test the heat storage function of the phase change heat storage dehumidification window prepared in the embodiment, simulation calculation is performed on the embodiment. In the simulation, only the heat conduction in the thickness direction of the phase change heat storage window is considered, and the influence of the dehumidification part on the heat transfer of the heat storage part is not considered. Taking a window as an example, the thickness of the phase change heat storage part window is 10 mm, and the structure is polycarbonate plate (PC plate), phase change material (sodium sulfate decahydrate), and polycarbonate plate (PC plate) from left to right. It is assumed that the initial temperature of the model window is 25 DEG C, and the outdoor temperature is constant at 38 DEG C. At x = 0 mm, the phase change heat storage window is in the outdoor, t = 38 DEG C; at x = 10 mm, the phase change heat storage window is in convective heat exchange with the water obtained by the dehumidification part, the temperature of the water is 25 DEG C, and the heat transfer coefficient h = 5 W / (m 2 ·K). The temperature change of a single point in the heat storage window with time is tested, and it is assumed that x1 = 5 mm and x2 = 9 mm are point 1 and point 2, respectively; and a control group is set, in which the material of the heat storage window is replaced by polycarbonate plate (PC plate), and the temperature change curves of the four points with time are simulated as shown in Figure 8 . It can be seen from the above test that the phase change heat storage window can better store heat and prevent the temperature of the indoor side window from rising too much.

[0069] In order to test the dehumidification performance of the phase change heat storage dehumidification window prepared in the embodiment, simulation calculation is performed on the embodiment. It is assumed that a room with a length of 6 m, a width of 6 m, and a height of 3 m has a temperature of 25 DEG C and a relative humidity of 90%, and is provided with a total area of 10 m 2 of dehumidification window, the humidity is 90%, the saturated water vapor density at 25 DEG C is 26 g / m 3 , and the room water vapor content is 6*6*3*0.9*26 = 2527.2 g. When the air relative humidity is 90%, the moisture absorption amount q of the one-way dehumidification film in 6 hours is 3.01 g / g / 6h, and the total moisture absorption amount formula Q = q*P*A*delta*t (P: material density, kg / m 3 , A: material surface area, m 2 , delta: thickness, m, t: time, h) is used to calculate that the dehumidification window absorbs 1.004 kg of water in 1 hour, that is, the dehumidification amount in 1 hour is 1.004 kg. The solar radiation evaporation rate is 1.4 kg / (m 2 *h), which can be completely evaporated, and the indoor relative humidity after 1 hour becomes: (2527.2-1004) / 2527.2*0.9 = 54.25% (without considering the air flow between indoor and outdoor).

[0070] The application combines heat storage function and dehumidification function efficiently, the heat stored by the phase change material can be used for regeneration of the dehumidification material, the heat is prevented from spreading from the outdoor to the indoor, and the solar energy is used as renewable energy to become the power for the regeneration of the dehumidification material, so that the energy is saved.

[0071] The above description of the embodiments is for facilitating the ordinary skilled in the art to understand and use the application. The person skilled in the art can obviously easily make various modifications to the embodiments, and apply the general principles described herein to other embodiments without creative labor. Therefore, the application is not limited to the above embodiments, and the improvements and modifications made by the person skilled in the art according to the disclosure of the application without departing from the scope of the application should be within the protection scope of the application.
