The first thing that one should understand when they look into the various convective heat transfer systems and their applications is that there are two basic types of phase conduction that take place. You can choose from Wet or Dry. A wet system involves using a fluid with a high vapor compression ratio, while dry systems involve a lower vapor compression ratio. Also, keep in mind that there are three different types of phase conduction:
A Dense Phase Conveying System sometimes called a Dense RCI or Density Compression System takes air, water, or both to transmit heat or cooling through fluids. The most common type of dense phase conveying system used today is the wet form. This is where the air is passed through a heating or cooling system in an enclosed container. There are many different types of containers that can be used for this, including, but not limited to, polyethylene, polypropylene, polystyrene, carbon fiber, foam, and others. The materials that can be utilized for this system are highly dependable and they all work as advertised.
If a Dense Phase Conveying System is used in a hot area, there is the possibility of damage to the building and/or the occupants of the structure. There is a chance that the air in the container may be forced through cracks or breaches in the structure, which will cause pressure to build up and cause further damage. Also, if the system is used in a cold area, it may cause dew point depression, where the temperature starts to drop, causing even more deformation of the materials being conveyed. If this happens, it is very likely that you will receive a poor performance from your system. Dense conduction can be extremely fragile, so it is vitally important that proper precautions are taken when implementing it into your heating or cooling system.
If you are considering a Dense Phase Conveying System, then you should consider the types of materials that can be used with it. In many instances, the material is able to maintain the same pressure throughout the entire system, but depending on the nature of the materials, you will find that the maximum pressures can be maintained at approximately ten pounds per square inch, although this is not always the case. Some of the common materials used with this type of system include polystyrene, polycarbonate, polystyrene beads, and polyurethane foam, among others.
Important Points to Consider for A Dense Phase Pneumatic System
One of the most important things to understand about a Dense Phase Conveying System is that it is able to work with both oil and water-filled media. This is incredibly beneficial because the ability to use these two fluids with ease allows for the creation of various pumping solutions that can help to remove any amount of dust or other debris from the air. These pumps can also work to create suction which draws in and captures any particles that are in the fluid. Once these particles are captured, they are then removed and conveyed through the system until they are no longer a hazard to anyone's health. This is an extremely important thing to understand, especially in the event that a vacuum cleaner is needed to clean up materials in an environment.
The next thing to take a look at when it comes to using a Dense Phase Conveying System is that the equipment itself does not have to be extremely large. A simple design that uses a series of small nozzles is often able to work just fine, as is a design that uses a single nozzle that is not particularly long. The fact that the materials are not very large in size makes it easy for the system to be able to work on a very small scale. Therefore, a dense phase conveying system is often an excellent choice for individuals that are looking to keep the cost of the system to a minimum.
