The split air conditioner in the home can only solve the problem of heating and cooling, but cannot solve the air treatment process. During the use of HVAC, the air outlet of the air conditioner will discharge hot air to provide a higher temperature airflow indoors, making the indoor environment warm and comfortable; but the hot air discharged from the air outlet of the air conditioner cannot be fully transported to the room. Due to the lack of a structural setting for recycling and reusing the waste heat, it leads to a waste of resources.
