Household Rooms

Before installing a HVAC system, it’s important to know what your venting system will require. Installing additional vents can make the installation cost more, but it will be well worth it if you need more airflow! So how many air vents should you have in your home?

Generally speaking, the square footage of each room will determine the number of vents you need per room. Because the influence of one vent will be altered when the room is larger than a certain square footage. If your room is larger than 100 square feet, then you’ll need at least two vents (the number will increase the larger your room). However, if the room is smaller than 100 square feet, you only need one vent.

If you're looking to upgrade your HVAC system, you need to check whether you have the right duct sizing in each room. Some of these calculations can be done on your own or using online calculators and charts, but for some figures, like duct friction, you may need to consult a professional to ensure accuracy. When considering the size of ducts, there are some components to keep in mind.

Hotel Rooms

Most of the hotel guests require their hotel room to be fresh, quiet and comfortable. The requirement for a system solution is to create an individually demand-controlled indoor climate while maintaining a high-level energy efficiency and cost-efficient operation. Here are some suggestions to make an efficient duct system for hotel rooms.

1. Avoid simple and direct ductwork paths between guestrooms and other guestrooms or corridor space. The longer and more complex/indirect duct work (ie., bends/turns in the ductwork), the better sound performance. This is especially applicable for hotels with directly ducted fresh air to the guestrooms.

2. Use Duct Liner. Most franchises and codes require insulated duct liners, which contain sound-absorbing material to reduce sound transfer within the ducts.

3. Use Soffits whenever possible. Soffits create a sound barrier of drywall between the noise source and the ductwork, even though sometimes limited by ceiling height requirements.

Pre-insulated ducts are made up of a rigid close cell polysocianate board or rigid phenolic insulated panels faced by an aluminum foil on both the side. They have many good features as following:

* Lower heat conductivity

* Light weight and low density

* Water-proof and sound-insulated

Pre-insulated ducts are commonly used in hotel ventilation system. Pre-insulated ducts are often produced byPID fabrication machines. PID fabrication machines are launched in recent years to improve the duct making process. An efficient PID fabrication machine is often computerized, with many good features.

- Rapid manufacture of ducting components.

- Simple or complex shapes produced with ease.

- Increased flexibility.

Traditional duct fabrication takes too much time measuring, adjusting, and cutting. It has to be done by professionals. Sometimes workers make mistakes and waste time. A PID fabrication machine measures precisely, and cuts at a max speed of 1500mm/s. PID fabrication machine the best option for contractors and duct factories who have lots of work in hand! Where to find a perfect PID fabrication machine? You can search PID fabrication machine on Google,VENTECH is one of the most famous brand for PID fabrication machines.
