摘要： PURPOSE: To obtain an adiabatic damping structure having enough adiabatic and damping properties. CONSTITUTION: In an adiabatic damping structure consisting of a metal plate and an adiabatic damping layer which is integrated with the metal plate by fusion, the adiabatic damping layer is prepared by a method in which the layer of an adiabatic damping material containing asphalt, a filler, and a foaming agent is laminated on the metal plate, and the laminate is heated so that the layer of the adiabatic damping material is integrated with the metal plate by fusion and simultaneously expanded as large as 3-7 times in the thickness direction.

摘要： PURPOSE:To improve the effect of sound insulation and reduce the cost as well by forming a sound insulation member comprising two layers of a sound absorption material and a sound insulation material in three dimensions and covering a compressor and an accumulation so that a sound absorption material may be placed inside at least one of the compressor and the accumulator. CONSTITUTION:Bulky nonwoven fabric which comprises at least one type of natural or synthetic fiber, a synthetic resin bonding agent, and a flame resisting material, felt, and synthetic resin forming materials, such as urethane and vinyl chloride are used as a sound absorption material while as a sound resisting material are used at least one type of binder component, such as asphalt, rubber, and synthetic resin, a filler component and an addition agent, which are kneaded and rolled into sheet shape. Then, a cylinder is adapted to be made of a two layer one piece member comprising the aforesaid sound insulation material 2 and sound absorption material 1 so that the sound absorption material may be placed inside, and the lapped parts may be bonded. In addition, the cylinder must be provided with an opening on one side. A compressor 3 or accumulator 4 having a support member is covered with this three dimensional sound proof material.

摘要： PURPOSE:To get a sound absorbing material for a conditioner which is superior in the effect of absorbing sound and in sealing characteristic by a method wherein a specified portion is covered by a sound-absorbing material having three layers formed in a cubic form. CONSTITUTION:A sound-absorbing member composed of three layers of a sound- absorbing member 1/a sound-shielding member 2/a sound-absorbing member 1' is integrally formed and worked in a cubic form to get a cylindrical body having an opening end. It may cover either one or both of a compressor 3 and an accumulator 4 within an outdoor air conditioner unit. As the sound- absorbing member, a bulky non-woven fabric composed of more than one fiber of plant, animal, ore and synthetic resin and synthetic resin binder and a fire- proof agent and the like and a synthetic resin foam such as a felt, urethane and vinyl chloride can be used. The sound-absorbing member 1 and the sound- absorbing member 1' are not necessarily the same. As the sound-shielding member, one or more binder components such as asphalt, rubber and synthetic resin and the like and a filler component are mixed to each other and kneaded so as to get a rolled sheet material.
