Abstract

The paper presents measurements of mechanical, acoustical and thermodynamic parameters of an air handling unit according to HRN EN 1886. Measurements are conducted in premises of company PRO-KLIMA to determine the real characteristics of newly developed AHU casing, because of it classification and finding of “weak spots” which should be “eliminated” in further development of casing construction. Sound produced by air- handling unit can be significant source of annoying noise. It is very important to measure acoustic parameters of air- handling units in purpose to reduce the sound power level radiated from these types of sound sources. The measured acoustic parameters of air handling unit in this research are: acoustic insulation of casing, outlet in-duct sound power level, inlet in-duct sound power level and airborne sound power level in octave bands of interest. The results of measurements carried out are shown together with analysis of possible measures for improvements. Project is conceived as incentive for company PRO- KLIMA on establishing and furnishing own factory test rig, with intention to collect all necessary mechanical, acoustical and thermodynamic data for development and improvement of air handling unit construction.
