The outside air 10 can bypass the dehumidification wheel 51, mainly when the dehumidification wheel 51 fails, the dehumidification wheel 51 is adsorbed saturated or other force majeure factors occur, in order to avoid the outside air treatment system 40 from being unable to operate, a bypass facility for changing the direction of the airflow is designed.

[0092] Therefore, the utility model mainly adopts a combination design of an outside air 10, an outside air conditioning unit (MAU) 20, an air duct 30, an outside air treatment system 40 and an incineration device 60, so that the waste heat discharged by the incineration device 60 can be provided to the dehumidification wheel 51 of the outside air treatment system 40 to remove the latent heat of the outside air 10, and then transported to the required place through the air duct 30. Therefore, the load of the outside air conditioning unit (MAU) 20 can be greatly reduced, and at the same time, it has the efficiency of heat recovery application and energy saving and carbon reduction, and can also achieve the effect of reducing energy costs, thereby increasing the overall practicality.

[0093] The embodiments of the present invention are described above. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although the embodiments are described above separately, this does not mean that the measures in the various embodiments cannot be used in combination to advantage. The scope of the present invention is defined by the attached claims and their equivalents. Without departing from the scope of the present invention, a person skilled in the art may make a variety of substitutions and modifications, which should all fall within the scope of the present invention.
