Project introduction: zhangzhou caux 01 massif, the third floor dining lampblack machine room, wind plum sand education and east, west, south shops and yong hui supermarkets air-cooled heat pump units, installed on the 1 # commercial roofing, soot blower installed within the wind machine room and row FengKouChu noise is about 75-78 dB (A), air-cooled heat pump units and the pump running noise is about 70-75 dB (A), the noise of the above equipment run time 1 #, 9 #, 10 #, # soho1 residents living environment impact.

Treatment measures: set air inlet and exhaust muffler, install air cooling module, cooling tower sound insulation cover, etc. The air inlet and exhaust muffler is an impedance muffler which can stop the sound propagation and allow the airflow to pass. It is an important measure to eliminate the aerodynamic noise. The sound insulation cover is made of porous aluminum plate, composite aluminum silicate cotton, steel frame, etc., which effectively isolates the noise of the unit within the sound insulation cover.

Governance effect: meet the design and use requirements, in strict accordance with the design drawings and construction acceptance code for construction, in line with the national, local, industrial construction and acceptance code, quality inspection and evaluation standards. The project quality acceptance grade: excellent.
