Improvement in Prediction Accuracy of Air Conditioning Noise from Vessels

Abstract

Various technologies are being developed for noise prediction at the design stage of vessels. However, research on noise level prediction technologies for air conditioners and each section connected to these systems has not been actively pursued up until now. This results in low prediction accuracy of air conditioning noise at the design stage, causing some ship designers have no choice but to introduce excessive noise control measures. To address this issue, we have developed a new air conditioning noise calculation method after conducting various experiments. This method allows appropriate noise insulation measures to be adopted at the design stage of a new vessel. In this paper, we describe the outline and results of the above-mentioned experiments.
