Abstract
This article describes test methods on air duct track in Laboratory of Environmental Engineering. It focuses on measurement of silencer parameter like is pressure loss coeffcient. Firstly, the paper describe the measurement apparatus with description of calculation method by standard ISO 7235 and energy equation. Then the paper presents three ways how to accomplish measurement because such way is not covered by procedure in standard. Then follows the evaluation of results of measurements on three types of silencer designed for HVAC applications. The article is concluded with discussion over measured data with outline for further research.
Highlights
Aerodynamic properties of air is in the scope of interest of researchers for more than century
There is a possibility to measure minor loss coefficient of any equipment determined for installation inside a duct
There is taping mount on ducts for measurement of static pressure before and after surveilled object. Such measurements and consequential calculations are in scope of this article
Summary
Aerodynamic properties of air is in the scope of interest of researchers for more than century. Determination of parameters for specific HVAC devices are in scope of specialized laboratories. Laboratory of such capabilities is maintained by authors of this article at Tomas Bata University in Zlin, Faculty of Applied Informatics and is involved in this paper. The focus is on measurement methods described by standard ISO 7235 [6] and comparison of results obtained by this standard with analytical calculations with different approach This standard lacks any details how to accomplish such measurement of friction losses. Investigation of such procedure is the subject of presented paper, where three possible ways hot to executed measurement of silencers are compared
