[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] like Figure 1 , 2 As shown, in order to achieve the above-mentioned purpose, the present application provides a smart window fresh air system for achieving micro-environment carbon neutrality, which is mainly composed of a shell 1, a partition 6, a ventilation fan 2, a filter 3, a heat exchanger 4 and a control system.

[0029] The control system is mainly composed of a temperature sensor, a humidity sensor, an air quality sensor, a microprocessor 5 and a controller. The temperature sensor, the humidity sensor and the air quality sensor are all fixed on the side of the shell 1. The temperature sensor, the humidity sensor and the air quality sensor are respectively connected to the microprocessor 5. The microprocessor 5 is connected to the controller, and the controller controls the heat exchange fan.

[0030] A fixed frame is installed on the window, slide rails are installed on the inner side walls of both sides of the frame, and pulleys 9 adapted to the slide rails are installed on the outer side walls of both sides of the shell. The shell is slidably installed in the frame.

[0031] A partition 6 is installed in the middle of the shell 1 to divide the shell into an air inlet chamber 7 and an air outlet chamber 8. The ventilation fan 2 is fixedly installed in the air inlet chamber 7 and the air outlet chamber 8. An axial flow fan is adopted, wherein the air inlet fan is in the air inlet chamber 7, and the air outlet fan is in the air outlet chamber 8. The air inlet fan and the air outlet fan are arranged side by side, and the filter is fixed at the air outlet of the air inlet fan and is connected and fixed to the shell.

[0032] The heat exchanger 4 is fixed between the vent on the outside of the shell and the ventilation fan. The heat exchanger 4 is mainly composed of a heat pipe heat exchanger 41 and a heat exchange plate 42. There are seven heat pipe heat exchangers 41. The heat pipe heat exchangers 41 pass through the partition, and the two ends are respectively located in the air inlet cavity 7 and the air outlet cavity 8. There are multiple heat exchange plates 42, which are connected to the heat pipe heat exchangers and fixed in the air inlet cavity and the air outlet cavity, respectively, to form multiple air inlet and air outlet ducts, such as Figure 3 shown.

[0033] Intake fan and exhaust fan There are two intake fans and one exhaust fan, with a total length of 600mm. The air inlet of the intake fan and the air outlet of the initial fan are both provided with louvers 10, with a width of 8-12mm, a spacing of 15-20mm, and an angle of 30°-45°. Example

[0034] In this embodiment, the parameters related to the louver blades of the air inlet are simulated, the louver data are changed, and the most suitable louver blade size is selected.

[0035] After experimental comparison, the average drag coefficient increases with the increase of blade width. The larger the average drag coefficient, the greater the pressure loss. Figure 4 , Figure 5 As shown in the figure, the guiding effect of blade widths of 12mm and 8mm on fluid is similar, while the guiding effect of blade width of 4mm is weaker. Therefore, blade widths of 8-12mm can meet the guiding effect, but in order to reduce resistance loss, blades with a blade width of 8mm are selected.

[0036] The average drag coefficient decreases as the angle between the blade and the inlet wall increases; the pressure loss at a blade angle of 30° is large, resulting in a large change in the velocity of the fluid after it exits the blade, which is not conducive to air flow. Blades of 30°-45° are more suitable, and the velocity of the fluid exiting the 45° blade is significantly higher than that of the 60° blade, so a 45° blade is selected for simulation.

[0037] In summary, the blade parameters selected model 3, that is, the blade parameters are: height 200mm, width 8mm, thickness 1mm, blade spacing 20mm, and inclination angle 45°. Example

[0038] In this embodiment, the height of the louver blades is 200mm, the width is 8mm, the thickness is 1mm, the blade spacing is 20mm, the inclination angle is 45°, the fresh air system of this application is set at a height of 2.5m, the ambient temperature is 26°C, and the relative humidity of the air is 70%.

[0039] In the environment described above, the indoor velocity cloud map shows that the upper limit of indoor air wind speed is 0.3m / s, which meets the indoor environmental requirements. The indoor pressure is in a positive pressure environment of 1.55-2.64Pa, which meets the requirements of a healthy living environment.

[0040] During actual use, the temperature sensor, humidity sensor and air quality sensor of the present application will sense indoor and outdoor environmental data in real time, analyze the data information through the microprocessor, convey instructions to the controller, and control the fresh air system.

[0041] When outdoor air quality is poor, turn off ventilation fans and blinds to cut off air circulation between indoor and outdoor areas.

[0042] When the indoor air quality is poor, turn on the ventilation fan and blinds to exchange air between indoor and outdoor to improve indoor air quality.

[0043] At the same time, during the air exchange process, the filter in the air inlet cavity will also filter the air, further improving the indoor air quality. When the air passes through the fresh air system, it will first pass through the heat exchanger. When the air passes through the air duct composed of the heat exchange plate, heat exchange will be carried out. The heat will pass through the heat pipe heat exchanger. The heat will complete the exchange between the air outlet cavity and the air inlet cavity, reducing the impact of outdoor air on indoor temperature.

[0044] When the outdoor temperature is higher than the indoor temperature, the fresh air system exchanges indoor and outdoor air, and lowers the temperature of the air entering the room through the heat exchanger. When the outdoor temperature is lower than the indoor temperature, the fresh air system exchanges indoor and outdoor air, and raises the temperature of the air entering the room through the heat exchanger.

[0045] When cleaning and maintenance are required, since the shell is connected to the window frame through pulleys and slide rails, you only need to pull the shell of the fresh air system to pull it out as a whole for cleaning and maintenance, which is simple and convenient.

[0046] The advantages of the smart window fresh air system for achieving micro-environment carbon neutrality in this application are:

[0047] The present application realizes the smart window fresh air system in the micro-environment carbon, and realizes the exchange of indoor and outdoor air by setting up air intake and exhaust fans. The outdoor air enters the room after being filtered, thereby improving the indoor air quality. At the same time, a heat exchanger is provided to maintain the balance of indoor temperature.

[0048] At the same time, the number of ventilation fans and detailed data of blinds are redesigned, and the indoor temperature, humidity and other data are calculated to achieve the optimal effect and further improve the indoor livability.

[0049] Through the control system, indoor environmental data can be directly displayed, and manual adjustments can be made to change the operation of the fresh air system and improve human comfort.

[0050] The present application is described in detail above in conjunction with specific implementation methods and exemplary examples, but these descriptions cannot be understood as limiting the present application. Those skilled in the art understand that, without departing from the spirit and scope of the present application, a variety of equivalent replacements, modifications or improvements can be made to the technical solution of the present application and its implementation methods, all of which fall within the scope of the present application. The scope of protection of the present application shall be subject to the attached claims.
