Abstract
The utility model discloses a silencer for a refrigerating system for an air conditioner. The utility model comprises an inlet connecting pipe, an outlet connecting pipe, and an expanding chamber pipe, wherein, both ends in the expanding chamber pipe are respectively extended and connected with the inlet connecting pipe of a cantilever and the outlet connecting pipe of the cantilever. The length L1 of the inlet connecting pipe and the length L2 of the outlet connecting pipe are respectively determined as the L1 = (1/4-1/2) L and the L2 =(1/2-1/4) L. The pipe diameter of the expanding chamber pipe is D 1 =(2-6) D2, and the D2 is the pipe diameter of the expanding chamber pipe. Through an experiment, the utility model which s applied to a KFR-25 CW* 2/E type air conditioner has obvious silencing effect.
Description
The utility model relates to the improvement of the parts of air-conditioner, especially a kind of muffler of air-conditioner refrigerating system, and it belongs to the air-conditioner technical field.
Existing air-conditioner all has the operation noise problem.Muffler generally all is set on the suction pipeline of refrigeration system.This muffler adopts the muffler of expansion chamber.Its noise reduction frequency range is narrow, and have under the noise of certain frequency can not noise reduction phenomenon.Also have a kind of muffler, load " sound-absorbing " material in its expansion chambers, utilize these material absorbing sound and lowering noises, its effect is not so good, and the cost height, complex structure, and weight is big, is not suitable for using on the domestic air conditioner.
The purpose of this utility model is to design a kind of muffler of novel air-conditioner refrigerating system.This muffler is simple in structure, is easy to make, and has the noise reduction frequency range of broad, and its erasure effect improves flat effect 4dB than general expansion chamber muffler.
Task of the present utility model has following technical scheme to finish, developed a kind of muffler of air-conditioner refrigerating system, it comprises: into and out of taking over and the expansion chambers pipe, in the expansion chambers pipe of preseting length L, prolong to stretch from the import of this chamber pipe and the port of export respectively and be connected to advancing to take over and going out to take over of cantilever, this two length of taking over is respectively: L
1, L
2, two mouths of pipe in the pipe of this chamber at a distance of (1/4-1/8) L, the corresponding length L of advancing adapter
1=(1/4-1/2) L is or/and the length L that goes out to take over
2=(1/2-1/4) L.
The muffler of this air-conditioner refrigerating system, described into and out of taking over L
1, L
2, the caliber D that it is identical
2Be chosen at 4-16mm.
The muffler of the refrigeration system of this air-conditioner, described expansion chambers pipe, its preseting length L is chosen at 100-200mm, the caliber D of this chamber pipe
1=(3-4) D
2
Muffler of the present utility model, its advantage is: meet the outstanding into adapter L that is inserted with owing to prolong to stretch in the expansion chambers pipe
1With go out to take over L
2, make the sound wave that enters in the expansion chambers pipe in this ependymal cavity, experience different lumen interfaces: sudden expansion interface and reflecting interface are arranged.Through the sound wave phase difference at these two kinds of interfaces just in time is 180 degree, and amplitude also equates, so two kinds of sound waves in this chamber pipe can interfere mutually and offset, thereby reaches the purpose of noise reduction.Because the length L of choosing the expansion chambers pipe is at 100-200mm, and with caliber D
1=(3-4) D
2Guarantee sound wave at sudden expansion space attenuation energy, thereby realize the effect of noise reduction.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the muffler structure cutaway view of air-conditioner refrigerating system.
The muffler of the civilian air-conditioner refrigerating system of making referring to Fig. 1, it comprises: into and out of taking over 1,2 and expansion chambers pipe 3.The length L of having set expansion chambers pipe 3 is at 120mm, in this chamber pipe 3 respectively from the entrance point of this chamber pipe 3 and the port of export be welded with prolong stretch the cantilever that connects advance to take over 1 and go out to take over 2.The length of these two adapters 1,2 is respectively L
1L
2This two mouth of pipe in this chamber pipe 3 at a distance of (1/4-1/8) L, the corresponding length L of advancing adapter 1
1=(1/4-1/2) L is or/and go out to take over 2 length L
2=(1/2-1/4) L.This example is selected the length L of into adapter 1
1=30mm goes out the length L of adapter 2
2=60mm, these two pipes, 1,2 mouths of pipe are at a distance of 30mm.Be D wherein into and out of the caliber of taking over 1,2
2=8mm, then the caliber D of expansion chambers pipe 3
1=32mm.Can reduce 4dB through testing its erasure effect, obvious erasure effect is arranged.
Claims (3)
1, a kind of muffler of air-conditioner refrigerating system, it comprises: into and out of taking over and the expansion chambers pipe, it is characterized in that: in the expansion chambers pipe of preseting length L, prolong to stretch from the import of this chamber pipe and the port of export respectively and be connected to advancing to take over and going out to take over of cantilever, this two length of taking over is respectively: L
1, L
2, two mouths of pipe in the pipe of this chamber at a distance of (1/4-1/8) L, the corresponding length L of advancing adapter
1=(1/4-1/2) L is or/and the length L that goes out to take over
2=(1/2-1/4) L.
2, the muffler of air-conditioner refrigerating system according to claim 1 is characterized in that: described into and out of taking over L
1, L
2, the caliber D that it is identical
2Be chosen at 4-16mm.
3, the muffler of the refrigeration system of air-conditioner according to claim 1 is characterized in that: described expansion chambers pipe, its preseting length L is chosen at 100-200mm, the caliber D of this chamber pipe
1=(3-4) D
