Commercial HVAC Ducting: Avoiding Design Defects During Sheet Metal FabricationShare
If your commercial HVAC ductwork is built poorly, you will experience a lot of inefficiencies in your building. In simple terms, faulty sheet metal pipework will cause air leakage, resulting in zones of varying temperature in the workplace. Some places will be cold while others will be hot due to this defect. Also, damaged pipes will affect the functionality and efficiency of the heating and cooling appliances. In addition, if the sheet metal ductwork is poorly designed, there will be a high risk of pollutants joining the indoor air circulation. You can avoid these problems through better ducting design during fabrication. Here are crucial guidelines to keep in mind for the best results.
Check Round and Rectangular Tubes
When fabricating and installing HVAC ducting, you should compare the benefits of using different structural shapes. In general, these ducts can be round or rectangular. Spiral or round ducts are favoured in commercial applications because their shape allows for smoother air flow. Consequently, there will be less noise coming from the ductwork. Also, it is important to note that these ducts are easier to completely seal from leaks, and you will need less sheet metal for fabricating ideal channels. Rectangular ducts are suitable for your needs if your installation space for the HVAC pipes is relatively small. Also, these structures are more stable, so they will require minimal maintenance.
Optimise the Length of Ducting Runs
You should plan on optimising your ducting runs when designing your new air distribution structure. In simple terms, it is important to create ducting runs which are perfectly suited for your building. When designing your piping, you should avoid creating long pipe runs between the equipment and the air distribution points. If the ducting is too long, there will be some significant energy losses. It is advisable to think about repositioning your HVAC appliances to reduce the total length of the piping. Also, consider designing the ducts as directly as possible with minimal corners.
Consider Incorporating Flexible Ducting
Finally, you should consider including some flexible ducting in your sheet metal pipework for your HVAC system. Flexible ducts are not suitable for use in the entire building because they are highly vulnerable to damage and deterioration, unlike the more resilient sheet metal alternatives. However, this type of ducting is the perfect choice for connecting the sheet metal pipes to the air outlets. Rigid pipes do not attach seamlessly to other components in the HVAC setup. Therefore, the flexible piping will allow for a smooth transition, promoting energy efficiency.
