Description
Technical field
The present invention relates to the pipe arrangement of air-conditioner, particularly at problems such as air conditioner piping vibration, noise and fractures and to the improvement technology of air-conditioner outdoor unit matched tube structure.
Background technology
The (see figure 1) that the matched tube structure of air-conditioner outdoor unit is made up of parts such as straight tube, bend pipe, silencer and cross valves, it is the pith that connects condenser and evaporimeter, because the vibration of compressor and the disturbance of tube fluid make piping vibrate.Strong piping vibration has brought serious harm to air-conditioning: the connecting portion that makes pipeline configuration, pipeline fittings produce fatigue rupture, particularly pipeline takes place loosening and breaks; Make the operating mode of compressor degenerate, valve block damages too early, has consumed compressor horsepower, has reduced the Energy Efficiency Ratio of air-conditioning; The outside radiated noise of pipeline configuration of vibration makes noise figure become big, and the quality of air-conditioning reduces.
Employing is in the structure (see figure 2) of the one or more U-shapeds of compressor circumferential directions usually with pipe arrangement for air-conditioner at present, and this matched tube structure mainly is in order to reduce the constraint of compressor of air conditioner to pipe arrangement, to avoid the transmission of compressor to the Analysis of Pipe Vibrations energy; But this piping stress is excessive, especially the hidden danger of first disconnected pipe of local (A place acute angle among Fig. 2) existence of turning at compressor outlet; And matched tube structure intrinsic frequency value major part drops in the low order range, and the frequency values of adjacent order is comparatively close, drops on easily in the resonance region of driving frequency, recurring structure resonance and air column resonance.In case the vibration values of pipeline test is excessive, the normal interim measures such as adding balancing weight 17, sticking anti-vibration rubber 16 that adopt are carried out the vibration damping de-noising, are difficult to guarantee the stable of the optimum and operation of design result, and the required copper pipe length of this matched tube structure is longer simultaneously, and material cost is higher.
Summary of the invention
The problem to be solved in the present invention is to overcome the deficiencies in the prior art, and piping is carried out dynamic simulation and optimal design, and a kind of air-conditioning off-premises station matched tube structure that reduces the pipeline risk of breakage is provided, and reduces the pipe arrangement cost.
Realize that technical scheme of the present invention is: a kind of piping for air conditioner outdoor machine, the blast pipe and the muffler that comprise compressor, it is characterized in that: described blast pipe comprises leading portion perpendicular to exhaust outlet of compressor, is connected to the back segment of cross valve, is connected by the linkage section that includes arc section at least between leading portion and the back segment; Described muffler is stepped, comprises the right angle or the obtuse angle bend pipe at two ends, and the middle linkage section that connects two bend pipes, and under the duty, the minimum point of described middle linkage section is not less than the height at compressor liquid storage can gas port last time place.
Also be provided with interlude between the leading portion of described blast pipe and the back segment, described linkage section comprises tangent connection leading portion and interlude and makes interlude to the shortest vertical range of leading portion be not less than the preceding linkage section of compressor radius and the back linkage section of tangent connection back segment and interlude.
The middle linkage section of described muffler is one or more snippets arc tube, perhaps is the combination of arc tube and straight tube.
Linkage section is one section semi arch pipe before described, and the radius of curvature of this semi arch pipe is greater than the radius of compressor.Linkage section is the combination of the arc section and the straight length of tangent connection before perhaps described.Linkage section is a plurality of arc sections of tangent connection before perhaps described.
Described back linkage section is one section semi arch pipe.Perhaps described back linkage section is the combination of the arc section and the straight length of tangent connection.Perhaps described back linkage section is a plurality of arc sections of tangent connection.
Have angle between plane, linkage section place and the plane, linkage section place, back before described, described angle can be according to the distance adjustment between compressor and the cross valve.
Piping for air conditioner outdoor machine provided by the present invention compared with prior art, its beneficial effect is:
1, avoids matched tube structure mechanical resonance.Matched tube structure intrinsic frequency value major part drops in the low order range at present, and the frequency values of adjacent order is comparatively close, and this is disadvantageous to avoiding resonance.Improve matched tube structure and improved its intrinsic frequency, make that the tube structure intrinsic frequency after improving is avoided dropping in the resonance region of fixed frequency air conditioner driving frequency, eliminate mechanical resonance, avoid the pipe-line system judder of (comprising auxiliary equipment and conduit fittings etc.).
2, avoid air column resonance and manifold pressure pulsation in the pipe arrangement.Higher pressure refrigerant gas in the compressor of air conditioner pipeline is called gas column, and this gas column is one quality, compressible vibration system, and it has a series of intrinsic frequency of oneself.At close compressor one end of gas column, because intermittently air-breathing periodically and exhaust of compressor, make gas column be subjected to the exciting force effect of one-period, when certain single order intrinsic frequency of the frequency of exciting force and gas column coincides, then the resonance corresponding to this frequency takes place in gas column, make the manifold pressure unevenness reach a maximum, the power that compressor consumed increases greatly, and makes pipeline do strong mechanical oscillation.Improved pipe arrangement has been avoided air column resonance in the pipe, has reduced compressor horsepower, has improved the Energy Efficiency Ratio of air-conditioning.
3, improved matched tube structure can reduce the stress of pipe arrangement and improve the stress distribution situation of pipe arrangement, improves air-conditioning in fatigue life, improves air-conditioning reliability of products in transportation and drop test process.
4, improved air conditioner piping can reduce the off-premises station sheet metal component of whole tubing, the connection of low pressure valve parts and all vibrations and the noise that whole off-premises station produces thereof.
5, copper pipe length of the present invention is short, and manufacturing is simple with assembly technology, reduces material cost and off-premises station manufacturing and assembly cost greatly.
