The air supply outlet sends the cooled or heated air to the room, while the air return outlet absorbs the indoor dirty air, forming a whole air cycle, which ensures the cooling and comfort of indoor air while ensuring the indoor cooling and heating effect. Air conditioning outlets are mainly divided into air return outlets, air supply outlets, inspection ports, and external wall outlets.
