Description
Technical field
The present invention relates to the parts improved technologies of refrigeration compressor, especially a kind of to be used for totally-enclosed reciprocating-piston system
More communicating pipe air-breathing silencing cavities of cold compressor.
Background technology
At present, in refrigerator（Refrigerator）It is by upper mute with the air-breathing silencing cavity in hermetically sealed compressor, generally used
Room, the means of communication of lower quiet room and dress between the chambers form, and the means of communication in traditional air-breathing silencing cavity is both designed as
Simply connected pipe structure, designs and produces simplicity, according to the displacement size of compressor, can select suitable communicating pipe aperture.Generally
In the case of, in order to reach higher Energy Efficiency Ratio, it can suitably select larger aperture.However in compressor displacement in more than 200W
When, select that suitable compressor means of communication aperture is particularly difficult, and aperture is big, compressor noise value can significantly rise；Aperture
Small, the gettering efficiency of compressor reduces, and cannot meet the performance requirement of current high efficiency compressor.With efficiency grade,
Energy-saving and environment-friendly idea is rooted in the hearts of the people, and high efficiency compressor is the inexorable trend of industry development, the inevitable requirement of Business survival.That
How to balance the design contradiction of noise and performance just seems particularly critical.
Invention content
Present invention aim to resolve the contradictory problems of air-breathing silencing cavity noise and performance, air-breathing noise reduction should be made
Chamber has good decrease of noise functions, while can improve compressor air suction efficiency again, designs a kind of mute chamber of multichannel air-breathing.
The present invention concrete scheme be：It is improved for existing air-breathing silencing cavity, it includes quiet room under
The means of communication composition of quiet room and dress between the chambers, and gas outlet is equipped in upper quiet room, lower quiet room is equipped with air inlet
Mouthful, it is characterized in that：There are one main communicating passages and several secondary communicating passages for design in means of communication.
Heretofore described main communicating passage is horizontal tube, VERTICAL TUBE or U-tube, can also be other shapes certainly.
It is heretofore described to set that there are one the secondary communicating passages of main communicating passage and one in means of communication.
Heretofore described main communicating passage internal diameter is φ 10- φ 12mm, wall thickness 4.5-5mm, total length 33-
35mm。
Heretofore described pair communicating passage internal diameter is φ 8.5- φ 10mm, wall thickness 4.5-5mm, total length 26-
30mm。
Totally-enclosed reciprocating-piston type refrigerating compressor mainly controls the cycle of refrigerant.Before ensureing that cycle is normal
It puts, we require loss of the compressor to energy and the influence to environment to reduce as far as possible, and the compressor service life adds as far as possible
It is long.In the case that wherein reduction energy loss is mainly manifested in identical refrigerating capacity, reduce input power, improve the COP of compressor
Value.
The gas transmission coefficient of compressor, i.e. total measurement (volume) efficiency λ=λ v × λ p × λ l × λ t, wherein λ v are bulk coefficient, and λ p are pressure
Force coefficient, λ l are leadage coefficient, and λ t are temperature coefficient.Refrigerant is discharged by compressing by exhaust pipe, is recycled from air intake duct.Recycling
Refrigerant entered inside air-breathing silencing cavity by air-breathing silencing cavity air inlet, since communicating pipe is not close with silencing cavity air inlet
Envelope be connected, between have a distance, by thermodynamic principles we understand before refrigerant enters communicating pipe, can expand rapidly,
Rather than rapidly entering communicating pipe immediately, some can be overflowed, and energy is released, and can play reduces noise at this time
Effect, but the refrigerant not being directly sucked in communicating pipe into cylinder overflowed has direct shadow to the air input efficiency of compressor
It rings, if communicating pipe aperture design more greatly, although convenient for the absorption to refrigerant, proving that this is unfavorable for making an uproar by testing
The reduction of sound.This some refrigerant has some that can be overflowed by the outage of silencing cavity, directly results in the leakage damage of refrigerant
It loses, influences leadage coefficient λ l, also have certain influence to pressure coefficient λ p；Separately there are some that can pass through one section inside air-breathing silencing cavity
Enter communicating pipe after the flowing of time, during this period of time, the refrigerant of low temperature is by the heat transfer process liter of enclosure interior heat
Temperature, density become smaller, and in this way into cylinder, equally reduce the gettering efficiency of compressor.
The present invention is mainly while air-breathing silencing cavity noise reduction is fully ensured that, by increasing in air-breathing silencing cavity
One or more secondary communicating passage, the refrigerant for establishing spilling enter another channel of cylinder, refrigerant from air inlet into
After entering silencing cavity, failing to entering cylinder from main communicating passage, it can also carry and cylinder is entered by secondary communicating passage, thus to the greatest extent
It is possible to fully absorb in refrigerant to cylinder, the gas transmission coefficient of compressor is improved, the refrigerating capacity of compressor is improved, makes compressor
Energy Efficiency Ratio promoted.
Due to having major-minor communicating passage in the invention air-breathing silencing cavity, it may not be necessary to worry main communicating passage because of the small nothing of internal diameter
Method fully absorbs refrigerant gas stream.It therefore can be to the double-optimization design of major-minor communicating passage internal diameter, to ensure that high air-breathing is imitated
The noise of the reduction compressor of rate.
The present invention has the advantages that following notable compared with prior art：
1. the larger gas transmission coefficient for improving compressor improves the Energy Efficiency Ratio of compressor（That is COP values）；
2. the larger noise for reducing compressor can be got well.
