Grille air outlets can enhance indoor air quality, reduce building energy consumption, and achieve localized thermal and humidity control in large spaces, gradually becoming a significant trend in the development of air conditioning systems in office buildings today. This also poses new challenges to the design of traditional office air conditioning systems. The air supply outlets of grille ventilation are typically flush with the ground, requiring the ground to be elevated. The lower space is used for laying air supply pipes or as a direct air supply static pressure box. Air is supplied through the floor outlets and enters the room, where it undergoes a heat and mass exchange with the indoor air before being exhausted from the upper part of the room (ceiling or above the work area).
