Abstract
Cooling towers have been installed on rooftops or outside of buildings and widely applied to control the indoor temperature in residential areas and buildings. However, the noise and vibration resulting from their operation may cause problems in adjacent buildings. The purpose of this study is to measure the noise and vibration of an industrial cooling tower located adjacent to industrial plants and to investigate its influence on the surroundings according to an authorized evaluation standard. Further, in order to measure the effect of the vibration of the tower on the precision equipment inside the plant, an experiment is conducted to measure the vibration of the ground in the plant and the targeted precision equipment. The measurement results indicate that the noise in the cooling tower is 4 to 9 dB(A) higher than the maximum level defined in the standard of 68dB(A). The effect of the vibration of the tower on the precision equipment is comparatively minimal, because that in the supporting frame of the building is weaker than that on the floor where the precision equipment is located. The vibration of the floor on.
