New technology for improving comfort in air-conditioning has been developed recently. One of the most important technologies for comfort improvement in air-conditioners is to reduce the noise.
So, many studies to reduce the noise in air-conditioners have been carried out for several years. The technology to reduce the noise in air-conditioners depends on not only arrengement of unit components and development of noise reduction thchnology for fans but also advances in the field of vibration and noise reduction thchnology of compressors.
Therefore, we review the vibration and noise reduction thchnology with respect to small capacity positive displacement type compressors for room air-conditioners and packaged air-conditioners. And, we mention some recent technologies to the vibration and noise reduction.
