[0002] As we all know, a total heat exchanger usually refers to a fresh air and exhaust ventilation equipment containing a total heat exchange core; a total heat exchanger is a highly efficient and energy-saving heat recovery device that preheats or precools the fresh air introduced into the air-conditioning system by recovering the waste heat in the exhaust gas, and reduces or increases the enthalpy of the fresh air before the fresh air enters the room or the surface cooler of the air-conditioning unit for heat and moisture treatment.

[0003] When the existing total heat exchanger is in use, it will filter the dust on the fresh air entering the room from the outdoors. However, the mesh of the activated carbon filter used to filter the dust will be clogged after being used for a period of time. The activated carbon filter in the prior art is not easy to disassemble and clean, which leads to the fact that the convenience of using the filtering mechanism on the total heat exchanger still needs to be improved. For this reason, we propose a total heat exchanger with dust filtering function.
