[0023] The technical solution of the present invention will be further described in detail below through examples and in conjunction with the accompanying drawings. In the specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be construed as limiting the present invention.

[0024] In addition, in the following detailed description, for ease of explanation, numerous specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments can be practiced without these specific details. In other cases, well-known structures and devices are shown in diagrammatic form to simplify the accompanying drawings.

[0025] According to one of the general technical concepts of the present invention, a pre-filter structure for a fresh air system is provided to improve enthalpy efficiency. This pre-filter structure design allows airflow through the filter to flow at a more uniform speed, evens out airflow, and reduces the intensity of separation vortices. Simultaneously, simply by designing the filter's position, the fan's enthalpy efficiency is improved.

[0026] Figure 1 FIG. 1 is a top view showing an exemplary fresh air system according to the present invention. Figure 2 FIG. 1 is a side view of an exemplary fresh air system according to the present invention, wherein a housing of the fresh air system is omitted to more clearly illustrate a filter component and an air exchange component.

[0027] like Figure 1 and Figure 2 As shown, the present application provides a fresh air system 1, which includes at least one air inlet 11, at least one air outlet 12, an air exchange component 13 and at least one filter component 14, wherein external air enters the fresh air system through the at least one air inlet 11, and then the external air is guided through the filter component 14 to obtain an airflow with uniform air volume, the air exchange component 13 is used to replace the airflow passing through the filter component 14, and the air outlet 12 discharges the replaced air out of the fresh air system 1.

[0028] In one embodiment of the present application, the fresh air system 1 generally includes two air inlets 11 and two air outlets 12, and the two air inlets 11 and the two air outlets 12 are respectively located on both sides of the fresh air system. Preferably, as shown in the figure, one air inlet 11 and one air outlet 12 are located on the left side of the fresh air system, and one air inlet 11 and one air outlet 12 are located on the right side of the fresh air system. The air inlet 11 and the air outlet 12 on the left side can be connected to the outdoor part, and the air inlet 11 and the air outlet 12 on the right side can be connected to the indoor part.

[0029] The air exchange member 13 may include an exchange core to fully exchange the temperature and humidity of the indoor and outdoor air.

[0030] As shown in the figure, the filter member 14 can be two parts arranged side by side. The two parts are preferably identical to each other, including a frame 141 and a filter element 142, and the filter element 142 is fixed to the frame 141. Alternatively, in other embodiments, the two filter members 14 can also be set to be different from each other as needed. Alternatively, the filter member 14 can be an integral member. The filter member 14 is arranged near the air inlet 11 connected to the outside, that is, the air flow first passes through the filter member 14 after entering the fresh air system.

[0031] In other words, in the fresh air system structure with a pre-filter structure, before the airflow passes through the exchange core, it first passes through the filter, and after encountering the wind resistance of the filter, the air volume passes through the filter evenly, and then passes through the exchange core. The air volume is evenly distributed, and the generation of airflow vortices is reduced, so that the airflow is evenly distributed on the windward side of the exchange core, and the airflow enters the exchange core more evenly. In the process of passing through the exchange core, the temperature and humidity are fully exchanged efficiently. Under the condition of the same air volume and unchanged exchange core area, the enthalpy exchange efficiency is improved, thereby improving energy recovery.

[0032] In one embodiment of the present application, the filter member 14 is disposed between the air exchange member 13 and the air inlet 11. That is, after entering the fresh air system 1, the airflow first passes through the filter member 14 and then passes through the exchange core. This structural arrangement not only preliminarily filters the outdoor air, but also makes the airflow even after being subjected to the wind resistance of the filter, reduces the generation of airflow vortices, and makes the airflow evenly distributed on the windward side of the exchange core, so that the airflow enters the exchange core more evenly.

[0033] In one embodiment of the present application, as shown in the figure, the filter component 14 is arranged in parallel with the air exchange component 13, so that the uniform airflow is more evenly distributed on the windward surface of the exchange core, and the airflow enters the exchange core more evenly, thereby improving the enthalpy exchange efficiency.

[0034] In one embodiment of the present application, the filter element 14 is arranged on the windward side of the air exchange element 13, so that the temperature and humidity efficiency can be fully exchanged during the process of passing through the exchange core. Under the condition of the same air volume and the exchange core area remaining unchanged, the enthalpy exchange efficiency is improved and the energy recovery is improved.

[0035] In one embodiment of the present application, the surface area of ​​the filter member 14 matches the surface area of ​​the air exchange member 13, thereby preventing disturbance to the airflow and further improving enthalpy exchange efficiency and energy recovery.

[0036] In one embodiment of the present application, a filter member 14 is also provided between the air exchange member 13 and the air outlet 12 to guide the airflow more smoothly. Specifically, a filter member 14 is provided on one or both sides of the air exchange member 13. The provision of two filter members ensures that the air entering the room is cleaner and healthier.

[0037] In one embodiment of the present application, the at least one air inlet 11 includes an indoor air inlet 11 and an outdoor air inlet 11 , and the at least one air outlet 12 includes an indoor air outlet 12 and an outdoor air outlet 12 .

[0038] In one embodiment of the present application, the filter member 14 and the air exchange member 13 are detachably mounted to each other, thereby achieving more convenient and quick installation, and correspondingly improving work efficiency and reducing costs while achieving equivalent performance.

[0039] In another embodiment of the present application, the filter component 14 is detachably installed in the housing of the fresh air system relative to the air exchange component 13 .

[0040] In the aforementioned exemplary embodiments of the present invention, the placement of the filter element 14 before the air exchange element 13 can achieve uniform airflow and improve the enthalpy performance of the fresh air system. By designing the fresh air system, particularly the fan, with the filter placed before it, the uniform flow of air can be improved, eddy currents can be reduced, and a more uniform air intake can be achieved, thereby improving enthalpy efficiency.

[0041] In various embodiments of the present application, by pre-installing the filter element 14, the airflow is evenly distributed before entering the heat exchange core, reducing the generation of eddies, and improving enthalpy and cooling recovery by 3-5 percentage points. Furthermore, various embodiments of the present application are applicable to heat exchangers with filters and air volumes of 200-500 CMH.

[0042] Those skilled in the art will appreciate that the embodiments described above are exemplary and that they may be improved upon. The structures described in the various embodiments may be freely combined without causing any conflict in structure or principle.
