          Experts say that when we install the central air-conditioning, we should pay attention to the layout of the draught, which has a direct impact on the effect of the central air conditioning. Our staff need to perform according to certain installation standards, and the specific operation standards are as follows.

          1, air conditioning terminal equipment selection. After adopting the slot type air outlet in the outer room of air conditioning, the air distribution of air conditioning is greatly increased due to the restriction of architectural modeling, and the effect of air supply is not as good as that of diffuser. Generally, it is reduced to the direct air return of the ceiling, and the air conditioning load increases accordingly. Therefore, the model of the air conditioner fan coil or VAV box should be increased when conditions are considered.

          2, we should consider the difference between the inside and outside of the air-conditioner when arranging the air outlet. In the inner room, the air conditioning load is small and the change is small, the effect of air conditioning is easy to reach. In order to match the design of the building, the air distribution in the room of the air conditioning area can be a little worse than the air conditioning room.

          3. Check the wind speed of the export. The outlet wind speed of the slot type air outlet should be checked. The short length of the air supply and static pressure box will bring a sense of blowing to the people working below the slot type draught.

          4. The installation of the slit type tuyere. The narrow side width of the slit type draught is only 150 mm or 200mm, and the edge is very small. The size of the opening of the ceiling must be precise. When designing slit draught, we should avoid overlong and long slit draught.
