1. Fluoride extraction. 2. Leak detection.
3. Repair welding. 4. Constant pressure.
5. Evacuate. 6. Add fluoride.
The vibration of the ceiling air-conditioning unit is mainly generated by the rotation of the fan, which is transmitted to the floor structure through the pipe and the support and hanger, and the floor slab is affected by its vibration disturbance and will also produce low-frequency secondary structure-borne noise. If multiple noises are superimposed on each other, which is 20 dB(A) higher than the outdoor noise of the same sound source, the air conditioning room should take corresponding noise reduction measures.
In the direction of the vertical wind, the cross-sectional area of the static pressure box is consistent with the cross-sectional size of the air-conditioning box. 2 3 meters in the direction of the wind blowing.
Must install a good effect of the muffler, only the air outlet is estimated to be not good, I have encountered such a problem in the project before, and then the effect is significantly better after installing the muffler.
The heat exchange capacity of the fan coil unit is generally not very large, and a single unit rarely disperses more than 5 horses; And the ceiling wind cabinet can be done very large. The thickness of the fan coil unit is much smaller than that of the ceiling wind cabinet, and it is easy to hide in the ceiling. Now the end devices are all the same, the principle is the same, but the vertical air pressure of the wind cabinet is greater than that of the fan coil unit, and the common phrase is large space air supply.
The difference between the fresh air condition and the return air condition of the wind cabinet comes from the difference between the fresh air condition and the return air condition of the wind cabinet from Zhulong.com, and the content comes from the relevant high-quality information.
