| Abstract [eng] |
The master‘s work “the investigation of air handling unit and their silencers influence on the acoustic field” consists of introduction, three chapters, conclusions, literature source and additions. the volume of this work is 65 pages. There are 53 pictures and 8 tables in this work. The introduction sets the problem, the aims, the goals of the study and relevance of the topic. The first chapter provides an analysis of information sources and mathematical model. The second chapter describes in detail the experimental technique, which consists of: air handling unit (ahu) rirs 200 ve eko vibrational analysis of the individual units; the additional components of ahu – silencer‘s insertion loss investigation and acoustic investigation of low noise ahu prototype. The third chapter provides the results of the investigation of air handling unit and their silencers influence on the acoustic field, experimental research and their analysis. Also and a evaluation of ahu rirs 200 ve eko (when it is working on real operating conditions) acoustic excitation models adequacy test results. At the end of work contains formulation of conclusions and recommendations. |
