| Early commercial applications of air conditioning were | | | | efficiency ductwork. Compared with traditional metal |
| manufactured to cool air for industrial processing | | | | ductwork, one of major advantages of fabric |
| rather than personal comfort. For the last 20–30 | | | | ductwork system is the wide range of end airflow |
| years, manufacturers of HVAC equipment have been | | | | velocity and orientation control in a very precise |
| making an effort to make the systems they | | | | manner. Countless orifices could be opened on duct |

| The overall efficiency of a HVAC system is | | | | respectively, all based on system design and layout. |
| determined by AHU( air generator) and transmission | | | | There are of course more persuasive advantages |

| manufacturing process has not been easy. While, on | | | | easy to clean and maintain, condensation free, etc. |

| As mentioned above, the ductwork serves as a | | | | years. The soaring price of metal products and to be |
