Present invention is described below in conjunction with accompanying drawing, and wherein identical label is represented identical or similar assembly in all different accompanying drawings.
A reciprocal compressor according to the present invention comprises the housing 10 of a sealing, being used within it, the end portion of portion holds oil, one is used to switch on and produces the driver element 20 of power, and power that is used to utilize driver element 20 to produce sucks, the compression unit 30 of compression and discharging freezing mixture.
At first, vent silencer 50L and 50R are placed on two positions below the cylinder body 31 symmetrically, and fixing with cylinder body 31 with bolt.Be formed with a damping space 51 in the lower end of each vent silencer 50L and 50R inside.
Two coolant channel 52L that form in cylinder body and 52R link to each other and link to each other with 50R with vent silencer 50L respectively with drain chamber 32b (with reference to figure 1) in the cylinder cap 32.Cryogen discharge conduit 14 with one among vent silencer 50L and the 50R link to each other with cryogen discharge to extraneous, i.e. cool cycles (in the present embodiment, as shown in Figure 3, cryogen discharge conduit 14 links to each other with the vent silencer 50R on right side).
A connecting duct 60 is connected with each other vent silencer 50L and 50R so that reduce noise by destructive interference during the combination again at freezing mixture.Therefore, an end 61 of connecting duct 60 links to each other with left side vent silencer 50L and the other end 62 links to each other with right side vent silencer 50R, and therefore two vent silencer 50L and 50R communicate with each other by connecting duct 60.
In this case, connecting duct 60 should have certain length, and this length can make noise in the vent silencer 50L of left side opposite with noise in the vent silencer 50R of right side on phase place.
Below with detailed description determining to connecting duct 60 length.
By behind the connecting duct 60, opposite with noise in the vent silencer 50R of right side on phase place in order to make noise in the vent silencer 50L of left side, the length of connecting duct 60 should satisfy following equation:
L＝λ/2
Wherein L is the length of connecting duct 60, and λ is c/f, and c is the frequency of noise, and f is the velocity of propagation of noise in freezing mixture.
Illustrate, the frequency of the noise that produces in vent silencer 50L and 50R " c " is 350 to 600HZ, and the velocity of propagation in the freezing mixture R134a that refrigerator is usually used is under the condition of 161m/s (at 100 ℃ time), the length L of connecting duct 60 preferably 13.4 to 23cm.
Therefore, the noise in the vent silencer 50L of left side is delivered to by connecting duct after the vent silencer 50R of right side, becomes opposite with the phase place of noise in the vent silencer 50R of right side from the phase place of the noise in the vent silencer 50L of left side.Noise on the left of this makes in the vent silencer 50L is by the noise in the destructive interference counteracting right side vent silencer 50R.
In reciprocal compressor, can easily eliminate noise with certain frequency band by the length L that changes connecting duct 60.In addition, if clearly the internal diameter of connecting duct 60 is carried out suitable adjustment, also can easily eliminate noise with certain frequency band as the length L that changes connecting duct 60.
Below, the running and the effect of reciprocal compressor of the present invention is described in detail.
After reciprocal compressor energising of the present invention, rotor 22 is together with the running shaft high speed rotating.This rotatablely moves and changes the straight line motion of piston 33 by connecting rod 34 into.
Correspondingly, piston 33 is reciprocally by pressing chamber 31a.When piston 33 was shifted to its bottom dead center or is in sucting stage, the freezing mixture of low pressure was inhaled into pressing chamber 31a by sucking silencing apparatus 40 and suction chamber 32a; When if piston 33 is shifted to its top dead or is in discharge phase, the freezing mixture of compression just is discharged in the interior damping space of drain chamber 32b and vent silencer 50L and 50R, and is discharged out seal casinghousing 10 by cryogen discharge conduit 14 continuously.Running shaft 23 rotates a week and should operation realize once.
During this period, the a part of freezing mixture that is discharged in the drain chamber 32b is sent in the vent silencer 50L of left side by left side coolant channel 52L, and remainder is sent in the vent silencer 50R of right side by right side coolant channel 52R, so pressure surge reduces.In this case, freezing mixture is discharged into the external world by cryogen discharge conduit 14.The compresses refrigerant that is sent in the vent silencer 50L of left side is discharged in the vent silencer 50R of right side by connecting duct 60.In this process, the noise of compresses refrigerant is cancelled.
As shown in Figure 4, produce one during the drain chamber 32b in compresses refrigerant is discharged into cylinder cap 32 (with reference to figure 1) and have sine-shaped first noise " A ", and when compresses refrigerant is sent to left and right side vent silencer 50L and 50R, produce and have also vent silencer 50L and the 50R transmission to the left and right of first noise " A " of certain frequency band by pressure surge.In other words, when compresses refrigerant is sent to left and right sides vent silencer 50L and 50R, can produce the second and the 3rd noise " B " and " C " that has same frequency band with first noise " A ".
Thereafter, the compresses refrigerant that is sent to right side vent silencer 50R directly is discharged into the external world by cryogen discharge conduit 14; And the compresses refrigerant that is sent to left side vent silencer 50L is sent to right side vent silencer 50R by connecting duct 60, and with right side vent silencer 50R in remaining compresses refrigerant combine again.
When the noise " B " in the vent silencer 50L of left side was sent to right side vent silencer 50R by connecting duct 60 together with compresses refrigerant, " B " became " D " and compares the phase difference with 180 ° with the noise " C " in the vent silencer 50R of right side.
Therefore, when the compresses refrigerant in the vent silencer 50L of left side by connecting duct 60 when compresses refrigerant in the vent silencer 50R of right side combines again, noise is cancelled by destructive interference.Therefore, the whole displacement noise of compresses refrigerant also correspondingly reduces.
During this period, although noise can be cancelled by the length L of adjusting connecting duct 60, yet, purpose of the present invention can also realize that wherein coolant channel 52L is connected with vent silencer 50L drain chamber 32b respectively with 52R with vent silencer 50R by length L 1 and the L2 that adjusts coolant channel 52L and 52R.
In more detail, in order after compresses refrigerant is sent to vent silencer 50L and 50R by coolant channel 52L and 52R, to make the phase place of noise opposite, drain chamber 32b and the left side discharging length that the length L 2 of the length L 1 of left side coolant channel 52L that device 50L is linked to each other and right side coolant channel 52R that device 50R is linked to each other that drain chamber 32b and right side discharging are eliminated the noise designs each other of eliminating the noise is different (in this embodiment, the length L 2 of the ratio right side coolant channel 52R of length L 1 design of left side coolant channel 52L is long, i.e. L1＞L2).
Correspondingly, discharge the noise that produces during the freezing mixture from cylinder cap 32 interior drain chamber 32b and be delivered to vent silencer 50L and 50R, so the noise in left and right side vent silencer 50L and the 50R has opposite phases by coolant channel 52L and 52R with different length L1 and L2.
The compresses refrigerant that is sent in the vent silencer 50L of left side is sent in the vent silencer of right side by connecting duct 60, and combine again with residue freezing mixture in the vent silencer 50R of right side, be discharged out seal casinghousing 10 together with the residue freezing mixture in the vent silencer of right side then.In this case, noise and compresses refrigerant in the vent silencer 50L of left side are delivered in the vent silencer 50R of right side by connecting duct 60 together, therefore transmit the noise that comes and the noise in the vent silencer 50R of right side in the vent silencer 50L of left side and are cancelled by destructive interference.Correspondingly, the whole displacement noise of compresses refrigerant all correspondingly reduces.
As mentioned above, the invention provides a kind of compressor that has silencing apparatus, wherein a pair of vent silencer be installed in symmetrically its cylinder body below, cryogen discharge conduit connects with one of them vent silencer and two vent silencers communicate with each other by a connecting duct.In this case, in the noise that makes freezing mixture in one of them vent silencer of the Design of length of connecting duct and another vent silencer the noise transfer of noise in previous vent silencer of freezing mixture phase place is opposite afterwards.Therefore, when the compresses refrigerant that is sent to a pair of vent silencer by connecting duct each other again in conjunction with the time noise be cancelled by destructive interference, so the whole noise of compresses refrigerant correspondingly reduces.In addition, can easily eliminate noise by the length that changes connecting duct with any frequency band.
Although for the purpose of illustration the preferred embodiments of the present invention are described in detail, for those skilled in the art, in not breaking away from thought of the present invention and scope, can make many modifications, add and displacement.
