| The center air-conditioning system is widely used in the public building and commercial building. When the air-conditioning syetem serve the people, it also brings the noise into the envirnment, which will impact people's work and live. The noise and vibration control of the air-conditioning system demand for the compositive application of the architecture, construction, HVAC, acoustic etc. But in many practical projects, the noise from air-conditioning system cannot meet the noise control criteria and pollute the environment for the HVAC engineers are short of the acoustic knowledge and the architects and the acoustic engineers are also short of the HVAC knowledge. This article research how to compositive control the noise from air-conditioning system more effectively and reasonedly.The research includes following parts:(1) The acoustic foundation, which includes the harm of noise and the sound rating system.(2) The codes and criterias for noise control engineering.(3) Characteristics of the air-conditioning noise and its transmission paths.(4) The air-conditioning noise control technology including the sound attenuation, vibration insulation, sound insulation, sound absorption etc.(5) The engineering application of the noise control technology. The practical application is an important part of the reasearch. The technology can be checked and be developed in the practical engineering. This part includes: the learning research of the air-conditioning noise control design for the China National Grand Theater, chairs outlet airflow noise experimental research for China National Grand Theater, the noise control design of the huge air cooler for the underground natural gas storage.
