[0002] Ventilation equipment for building energy conservation and emission reduction refers to equipment used to achieve air exchange in buildings, while saving energy and reducing emissions. While ensuring indoor air quality, these equipment can also effectively reduce the building's dependence on air conditioning, lighting and other systems, thereby reducing energy consumption and carbon emissions.

[0003] For example, the invention disclosed in the publication number CN115751551B discloses a ventilation device for building energy conservation and emission reduction, including a device box, one side of the device box is fixedly connected with a fresh air outlet pipe and an exhaust air inlet pipe, the other side of the device box is fixedly connected with an exhaust air outlet pipe and a fresh air inlet pipe, the fresh air outlet pipe and the fresh air inlet pipe in the device box are connected to form a fresh air channel, the exhaust air inlet pipe and the exhaust air outlet pipe are connected to form an exhaust channel, a four-sided heat exchanger is provided at the intersection of the fresh air channel and the exhaust channel, the fresh air channel and the exhaust channel circulate and exchange heat through the four-sided heat exchanger, and the fresh air channel of the device box is provided with a filtering mechanism. Both the new air and the dirty air pass through the four-sided heat exchanger, and heat exchange is performed in the four-sided heat exchanger to reduce the temperature difference between the new air entering the building and the original air inside the building, and prevent the new air outside the building from increasing the workload of the air conditioner when entering the building, thereby improving its energy conservation and emission reduction effect.

[0004] In the above-mentioned prior art, the indoor air and outdoor air are transported to the inside of the quadrilateral heat exchanger through the exhaust fan for heat exchange to reduce the temperature difference between the new air entering the building and the original air inside the building. However, after working for a long time, the exhaust fan will dissipate heat, and the heat it emits will flow with the inlet and outlet wind. Therefore, when the fresh air enters the room, its temperature will change. If it is summer or winter, the indoor temperature will be affected, and the filter plate will be filtered for a long time, and it will take time to disassemble, clean and replace it. During the disassembly and cleaning, the equipment needs to stop working, which will waste a lot of time. Summary of the invention
