1. The air outlet of the grille air supply is generally set flush with the ground.

2. The ground needs to be overhead.

3. The lower space is used for arranging air supply pipes or directly used as a static pressure box for air supply.

4. The air enters the room through the floor air outlet and heats up with the indoor air. After the mass exchange, it will be discharged from the air outlet in the upper part of the room (above the ceiling or working area).

5. The main difference of the grille air supply system is: it delivers air from the space under the floor; the air supply temperature during cooling is higher (generally 17-18°C); different local climate environments can be formed in the same large space; The indoor airflow is distributed from the floor to the ceiling, and the airflow pattern is from the bottom to the ceiling.
