Abstract

Heating, Ventilating and Air Conditioning Systems (HVAC) are applied for cooling purpose, maintaining quality of air and providing human comfort. Nowadays, galvanized sheet material were commonly used for ducting system. However, there are lots of issues from the duct system such as corrosion problem, heavy to install, high cost of maintenance, high initial cost, noise problem, leak problem and less duct efficiency. An efficient duct system designs can reduce equipment size and further saving money for new or replacement equipment. A new innovation project have produced cloth ducting system from fabric material to solve those problems. Fabric duct are able for all kinds of applications, ventilation requirements and also helps to provide a much more controlled velocity and comfortable environment. Recently, the air distribution for both duct are different. Galvanize steel duct is using spot duct air distribution method while fabric duct is using air diffusion across entire surface. Differences in air distribution method may contribute fabric duct to be more efficient than galvanize steel duct. Thus this study will involve both duct material to measure their duct efficiency by using spot cooling air distribution method. The duct material used are fabric and galvanized steel metal. The diameter for both duct are around 10 inch and 1.2 meter of duct length. The device used for measure all the parameters are anemometer TA465-P, Pitot tube differential manometer Extech HD350 vibration device (AT-2040) and sound meter level (Multifunction HVAC Meter PCE-EM 882). The measuring will be carry out for both duct material, galvanized steel and cloth fabric. The data obtain will be compare and analyzed with the theoretically method.
