Analysis of Split Air Conditioner Noise using Sound Intensity Mapping

This paper describes the noise generation and noise source identification for air conditioner noise using sound intensity method. Split unit air conditioners have an indoor unit and an outdoor unit connected by communication pipes. Noise can be reduced the efficiency and performance of the air condi...
