- Abstract
This paper presents an analysis aimed to evaluate the noise of micro-CHP systems. Based on the field test of insertion loss, the spectrum characteristics of CHP before and after the heat exchanger were analyzed. Finally the main source of noise is estimated, and the influence of speed and heat exchanger on noise is analyzed. The results show that the fundamental frequency noise is the main noise source, accompanied by other resonance noise. The increase of the rotation speed will cause the noise to move to the high frequency direction. System with heat exchanger can reduce high frequency noise.
