Vibration isolation noise reduction type air conditioner system for floating building and installation method thereof

Abstract

Aiming at the problem that only noise with one frequency or one sound source is improved, eventually, noise reduction is not thorough, and the using quality of a delivered building is affected in the prior art, the invention discloses a vibration isolation noise reduction type air conditioner system for a floating building and an installation method thereof. In the vibration isolation noise reduction type air conditioner system for the floating building, a machine room is located in a pipeline room; the floating building is located above the pipeline room; the space is saved, and the characteristics of noise reduction and energy conservation are achieved; the vibration isolation noise reduction type air conditioner system is suitable for music halls and other places; bearing vibration isolators are installed on vertical columns in the pipeline room, so that the whole floating building is suspended on the bearing vibration isolators; most of the weight of the floating building can be borne, and noise produced in the pipeline room and the machine room of the pipeline room can be prevented from being conducted into the floating building through a building envelope structure; tiny vibration and noise which are produced due to the flow velocity change of fluid inside an air hose can be absorbed through a noise isolation blanket attached to the air hose; and the interior of a ladder type stand is of a static pressure box structure, seating area noise absorption materials are pasted inside the ladder type stand, and noise reduction can be further achieved.

Description

Technical field [0001] The invention relates to a vibration isolation and noise reduction air conditioning system of a floating building and an installation method thereof, and is particularly suitable for occasions with strict restrictions on noise such as concert halls, libraries, theaters, and broadcasting halls. Background technique [0002] At present, some civil buildings with special functions have extremely high noise requirements. When the ventilation and air-conditioning system in the building is in normal operation, due to the large flow rate in the air duct, the high power of the compressed gas in the unit, the improper welding in the air duct and the outdoor Various sound sources are transmitted through air ducts and other factors, which often cause the noise reduction of the building to fail to meet the requirements; the author found in the actual air-conditioning system construction process of major theaters that due to the lack of related technologies and the incom...

Problems solved by technology

For example, Zhang Yiwei's invention patent (CN201210462984, publication date 2013-02-20) designed a foam sound-absorbing material produced from waste materials such as ceramics, and provided its preparation method. This process is suitable for use in music In the living room, it has the advantages of energy saving, environmental protection and long service life, but the patent only provides its manufacturing process and use, does not mention the specific installation process, and has the disadvantage of complicated manufacturing; the patent of Wang Guigang et al. (CN201220204682, published 2013-04-24) proposed a method for manufacturing a composite sound-absorbing coating for buildings. Although the product involved in this patent reduces the difficulty of the manufacturing process compared with the former, it also lacks a specific description of its application, and these two The objects introduced in the patent are all sound-absorbing materials, which cannot achieve the effect of vibration isolation and have limited noise reduction capabilities; Ge Zhen et al. invented a structure for sound insulation and heat preservation of a theater plenum (CN201120248168, publication date 2012-03-14), The advantage of this sound insulation structure is that it can effectively avoid the noise caused by the air pipe weld and the high-speed turbulence in the pipe installed on the top of the theater, but it is difficult to reduce the noise pollution in the concert hall to the specified level only by relying on this device. grade
