[0003] In summer, when the air conditioning fresh air system exchanges fresh air, the temperature of the fresh air brought in is also high due to the high outdoor temperature, and it needs to pass through a heat exchanger for heat exchange to lower the temperature of the air. However, in spring and autumn when the temperature is more suitable, there may be no need for heat exchange of outdoor air. But in the existing fresh air units, the air will still pass through the heat exchange core after entering the fresh air unit, which will reduce the service life of the heat exchange core and increase the customer's subsequent maintenance costs. Therefore, there is an urgent need for an air conditioning fresh air system with air purification function to solve the above problems. Utility Model Content
