In embodiments of the present invention, this compressor assembly includes compressor 161 and is connected to refrigerant pipeline 160 and the acoustic damping materials of compressor air inlet/position, gas outlet。Described acoustic damping materials wrap up all parts included by described compressor 161 and described refrigerant pipeline 160 respectively, and be filled between described compressor 161 and the parts of described refrigerant pipeline 161, so that described acoustic damping materials form entirety with described compressor 161 and described refrigerant pipeline 160。Wherein, acoustic damping materials include expanded material 150, noise reduction granule and/or noise reduction powder 170, acoustical cotton, elastic colloid etc.。Main purpose is in that by acoustic damping materials, each parts of refrigerant pipeline are wrapped up and coupled together, and makes acoustic damping materials and refrigerant pipeline form a complete entirety。Wherein, refrigerant pipeline includes gas-liquid separator, refrigerant pipe, cross valve and choke valve etc.。
When acoustic damping materials include expanded material 150, refrigerant pipeline is wrapped up and connects by expanded material 150, wherein parcel mode can include multiple as first wrapped up then integrated connection respectively, or directly being injected by expanded material 150 and carry out foaming etc. between each parts of refrigerant pipeline, detailed process is specifically addressed hereinafter。
When acoustic damping materials include elastic colloid, refrigerant pipeline is wrapped up and connects by elastic colloid, wherein parcel mode can include multiple as first wrapped up then integrated connection respectively, or is directly shaped between the liquid form injection each parts of refrigerant pipeline of elastic colloid。
When including noise reduction granule and/or noise reduction powder 170 when acoustic damping materials, noise reduction granule and/or noise reduction powder 170 are filled between each element of refrigerant pipeline, then pass through colloid, glue or expanded material 150 and noise reduction granule and/or noise reduction powder 170 are wrapped up connection。
The present invention is wrapped up by acoustic damping materials and connects refrigerant pipeline so that acoustic damping materials and refrigerant pipeline form an entirety, while reducing the noise that compressor produces, it is simple to the carrying to compressor assembly, are conducive to the assembling to off-premises station and maintenance。
In the following examples, by the parcel specifically introduced between multiple acoustic damping materials and refrigerant pipeline and annexation。
In the present embodiment, compressor assembly is used for air-conditioner outdoor unit, is installed in the cabinet 110 of off-premises station。Compressor assembly includes compressor 161 and noise reduction components, and noise reduction components includes expanded material 150 and noise reduction powder 170 and/or noise reduction granule。Expanded material 150 has host cavity, after compressor 161 is installed on host cavity, there is gap between compressor 161 housing and the sidewall of host cavity, noise reduction granule and/or noise reduction powder 170 is filled to gap。Noise reduction granule can include one or more in perlite particle, vermiculite granule, resin particle, rubber grain and silica gel particle。Noise reduction powder 170 can include one or more in perlite powder, Vermiculitum powder, toner, rubber powder and silica gel powder。
In the present embodiment; whether between granule and granule or between powder grain and powder grain; all there is gap; when sound is through granular layer or powder bed; sound wave will walk around granule or powder, connect in the passage formed in above-mentioned gap and propagate, and sound wave is in the process propagated; the ability of sound wave is converted to one or more in potential energy, kinetic energy or heat energy by powder or particulate absorbent, powder or granule by its energy。Large number of due to granule and powder, the transferable passage of sound wave formed is also many so that sound wave and granule are fully contacted, and is conducive to increasing the extinction efficiency of sound wave energy, thus being effectively reduced the propagation of noise。The vibration of housing is passed by noise reduction granule and the powder contacted, driving granule and powder are vibrated, granule and powder are deformed, make to rub between granule and between powder by vibration transmittance process between particles or between powder, even more so that granule and powder are subjected to displacement, so that the energy of vibration is converted into kinetic energy, potential energy (including elastic potential energy) and heat energy, the energy of vibration thus effectively having decayed, and then decrease the noise produced due to vibration transmission。
The softness of expanded material 150 own has elasticity, it is possible to the energy that compressor 161 vibrates is converted to the elastic potential energy of bubble material；Additionally, expanded material 150 has open-celled structure, bearing of trend along open-celled structure is transmitted by the vibration of compressor 161, in vibration transmittance process, hole wall is by elastic deformation repeatedly and reinstatement, constantly consuming the energy of vibration, the expanded material 150 simultaneously contacted with housing has a degree of vibration in vibration damping process, thus the energy of the vibration of compressor 161 is converted to one or more in kinetic energy, potential energy or heat energy；Meanwhile, elastic powder that expanded material 150 includes and elastic granule also elastic deformation repeatedly and recovery, the energy of vibration is converted to one or more in potential energy, heat energy or kinetic energy, constantly consumes the energy of vibration so that vibration is constantly weakened；In like manner, due to the vibration of compressor 161 housing, expanded material 150 vibration produced by sound, sound wave transmission process in, its energy also will be converted into heat energy or potential energy so that the volume that can pass out sound is little。
Wherein, foam plastics sound-absorbing material has applicable frequency compared with the advantage such as wide, cost is low, unit weight is little, moistureproof, sound absorbing capabilities is stable, and the introducing of micropore can improve toughness and the fatigue durability of material。Its sound absorbing capabilities within the scope of 500-1600Hz highlights, and equal acoustic absorptivity is more than 0.4, and maximum acoustic absorptivity is up to 0.92。The present embodiment is by adopting expanded material 150, and noise reduction particle powder and/or noise reduction granule, refrigerant pipeline 160 is carried out noise reduction simultaneously, refrigerant pipeline 160 all can be carried out sufficient vibration and noise reducing by noise reduction granule and expanded material 150, the noise that the refrigerant pipeline 160 including compressor 161 sends is reduced significantly, is conducive to using lower noise produced by the off-premises station of this compressor assembly。
Further, on the basis of above-described embodiment, with reference to the structural representation of the refrigerant pipeline that Fig. 6, Fig. 6 are compressor assembly of the present invention。
