Description
The invention belongs to refrigeration air-conditioner manufacturing and application
Known, noise is an important technology index of refrigeration air-conditioner.The noise of chiller plant and air conditioner is mainly from the vibration and the exhaust sound of compressor.For many years, owing to there is not the way of good reduction compressor noise, cheap wall-through type air conditioner is replaced by the higher separate type air conditioner of price gradually; Integrated type water-ring air conditioner with higher energy-conservation level can not become the air-conditioning form of main flow always owing to not solving the compressor noise problem; A lot of refrigeration air-conditioners are forced to be installed on basement owing to noise and vibration are excessive or are not adopted by the user.At present to solve the main way of noise be that compressor is isolated for chiller plant and air conditioner, is installed to outdoor or other are local, is divided into indoor set and outdoor unit as split-type air conditioner, and outdoor unit that will the band compressor hangs and is installed on skin.But such method makes an equipment be divided into two parts artificially, has not only increased manufacture cost and operation troubles rate, and can not use in all places.Other some vibration and noise reducing measures commonly used comprise: increase the pipeline loop, use damping glue fixing tube etc., these ancillary method effects are also not obvious.The utilization silencing apparatus of minute quantity is eliminated the noise and is handled, because what adopt is the technology of similar automobile exhaust muffler, acoustic wave filter structure is very complicated, and resistance is big, accumulates and pollutes the many shortcomings of freezing wet goods and can not widespread.
Owing to do not have the suitable silencer of performance, to now, generally all do not have to use to be installed on intrasystem independent air exhaust muffler device from the refrigeration air-conditioner invention.
Purpose of the present invention is intended to install a kind of novel exhaust silencing apparatus by with a kind of simple method additional in internal system, reduces vibration of compressor and noise, thereby reaches the purpose that reduces chiller plant and air conditioner noise with low cost significantly.
The inventor thinks through research for many years, the noise of refrigeration air-conditioner, main vibration and exhaust sound from compressor.The vibration of compressor can be eliminated by the flexible mounting type of compressor, therefore, exhaust sound has become topmost noise source, and its main communication channel is not the compressor case of generally being thought itself, but pulsing airflow diffuses to whole equipment with outlet pipe and connecting pipeline thereof.Take traditional mode vibration isolation sound insulation that the compressor fuselage is wrapped up and increase the fixing outside cancellation of damping glue on pipeline, its vibration insulation and noise reduction effect is also not obvious.The inventor thinks: vibration and the noise of effectively eliminating refrigeration air-conditioner, must start with by interior, from the isolated exhaust sound of exhaust outlet of compressor, prevent that exhaust from being the most effective vibration insulation and noise reduction way by pipeline with the various piece that exhaust is communicated to equipment with noise and vibration.Concrete mode be search out a kind of have simple in structure, resistance is little, do not accumulate and pollutes the high efficiency silencer of refrigeration oil, and it is installed on the compressor air-discharging outlet conduit, vibrate and the purpose of noise thereby reach to eliminate with plain mode.
The pipe type exhausting silencer equipment that generally adopts is automobile engine to exhaust silencing apparatus and similar structure product at present.This series products has good noise elimination effect, still, complex structure, gas-flow resistance is very big, and its internal structure and sound-absorbing material (as asbestos etc.) accumulate easily and pollute refrigeration oil.Then noise elimination effect simple in structure is bad, is difficult to meet the demands.Therefore the independent silencing apparatus that present little refrigeration air-conditioner employing is connected in behind the outlet pipe is applied in the reality.
The inventor has found a kind of noise elimination technique that can be applicable to this field---micro silencer technology through exploring for many years and studying.This technology applies to pneumatic tool and pneumatic valve field at present, as venting noise elimination cap, as Fig. 2.The great advantage of this noise elimination technique is that gas-flow resistance is very little, and inner no any sound absorbing material pollutes refrigeration oil, and refrigeration oil is accumulated at no back bending dead angle.And make simple, cheap.
Fig. 1 is the present invention who uses this art designs, a kind of exhaust silencer that applies to refrigeration air-conditioner.
This silencing apparatus mainly is made of micro silencer filter core and spindle metal shell.Shell is the containment vessel of whole silencer still not, and the interface device of pipeline was made by metallic material such as copper pipes before and after its two still connected, and enclosure has the joint that is connected with the micro silencer filter core.The space of the interior sudden enlargement of shell still is secondary silencer---anechoic chamber.The similar uncovered cup of the profile of micro silencer filter core, wall thickness is thicker.Its wall body inside is full of the micro-pore that is interconnected, and makes filter core inside and exterior, so that gas passes through.Its material can be the other materials that brass, stainless steel, powdered metallurgical material, pottery or engineering plastics etc. have stable chemical property.Micro silencer filter core opening portion firmly is connected with the joint of enclosure.
Compressor air-discharging is from entering the inlet of apparatus of the present invention after its relief opening comes out, direction shown in left arrow among Fig. 1, go into micropore noise elimination filter core by connection part is laggard, from the micropore of micro silencer filter core, pass through, because micropore has strong noise elimination and eliminates the effect of air-flow pulse, and its gas-flow resistance is very little, and after air-flow came out, noise and pressure pulse were decayed significantly.After air-flow comes out from the micro silencer filter core, enter suddenly in the relatively large anechoic chamber, space, its speed slows down, and pressure reduces, and noise and air-flow pulse are further eliminated.The air-flow that reduces for twice behind noise and the pressure pulse is last gently from the outlet discharge at shell rear portion, and direction shown in right arrow among Fig. 1 is finished whole noise elimination vibration damping process.
The present invention and the outside noise elimination technique that generally adopts at present as: increase fixedly damping glue to compressor parcel sound insulation felt, pipeline and compare, eliminate the noise effective a lot;
Compare with the silencing apparatus of taking non-micro silencer technology, with low cost, simple in structure, resistance is little, and no refrigeration oil pollutes and the trapped fuel dead angle.
Compressor noise after employing the technology of the present invention can reduce about 10 decibels than the compressor noise that does not generally adopt independent silencing apparatus at present, and effect is very obvious.
Accompanying drawing 1 is the structural representation of apparatus of the present invention;
Accompanying drawing 2 is mainly used the pneumatic noise elimination cap schematic representation of technology for the present invention;
Accompanying drawing 3 is a kind of specific embodiments figure of the present invention.
As shown in Figure 3, but be a kind of embodiment.Entry end and joint are the one-piece element of a brass material, constitute the preceding half of shell, and the micro silencer filter core firmly embeds wherein by sintering.The later half fine copper material that is truncated into of shell, with preceding half be the frame of a complete sealing by being welded.
Compressor air-discharging enters from entry end, after passing from the micro silencer filter core, and a vibration-absorbing and silencing; Enter space sudden enlargement in the shell, airspeed is slack-off, is compressed acceleration again in the outlet port, and the secondary vibration-absorbing and silencing goes out silencing apparatus then and finishes whole vibration-absorbing and silencing process.
