Yixing technology supplies and fabricates ventilation systems, duct and fittings out of PVC, CPVC, ABS and Polypropylene.
The advantage for plastic Ventilation Systems
1. Low installed cost when compared to noncorrosive metallic.
2. Light weight allows for ease of handling, installation, and reduces labor costs .
3. Low maintenance requirements over extended service periods.
4. Flame retarded material make it more safe .
it has certain advantages, but also has certain application conditions. Generally, it is applicable to the places where the pollution source is related to the heat source, and the floor height is not less than 2.5m, at this time, the dirty air is easy to be taken away by the buoyancy wake; There is also a upper limit for the design cooling load of the room. The research shows that if there is enough space for a large-scale air supply and distribution device, the room cooling load can reach **0W / ㎡, the room cooling load is too large, the power consumption of displacement ventilation will be significantly increased, and the economy will be reduced; in addition, the contradiction between the floor area and space occupation of the air supply device is more prominent
