原因となる。The distributor constructed as described above is provided with a perforated plate or an orifice for refining droplets of a gas-liquid two-phase refrigerant flow. The pressure loss of the perforated plate or the orifice becomes very large. This increases the refrigerant flow noise. The reason will be described with reference to FIG. The high-temperature and high-pressure refrigerant gas from the compressor 1 becomes low-temperature and high-pressure gas in the condenser 2 and is further decompressed by the expansion mechanism 3.
The refrigerant is sent to the distributor 7 through the pipe 6 as a gas-liquid two-phase refrigerant flow, distributed to each distribution pipe 8, and sent to the evaporator 4. At this time, if a perforated plate or an orifice is installed in the distributor 7 as in the conventional distributor, the droplets of the gas-liquid two-phase refrigerant flow are made finer, and the refrigerant flow noise colliding with the droplets is generated. Although the pressure is reduced, the pressure of the refrigerant after passing through the expansion mechanism 3 is larger than that when the perforated plate or the orifice is not installed in the distributor 7 because the pressure loss in this portion is large. For this reason, the flow pattern of the gas-liquid two-phase refrigerant flow flowing into the distributor 7 is as follows:
Droplets become larger. Therefore, even if a perforated plate or an orifice is installed, since the flowing refrigerant droplets are large,
In many cases, there is no effect of the fine graining. When a larger droplet collides with the inner wall surface of the distributor, a larger impact vibration or a refrigerant flow noise due to the impact is generated. As a result, even if a perforated plate or orifice is installed, the refrigerant flow noise generated in the distributor and the impact vibration generated by the impact of the droplet are not reduced,
It is necessary to attach a large amount of vibration damping material, which is a measure for conventional air conditioners, to distributors and distribution pipes. In addition, when the droplets are large, the distribution of the refrigerant to the distribution passages tends to be biased, which causes a decrease in performance.

In addition, the configuration is such that the refrigerant flow noise at the time of collision of the droplets is absorbed and the droplets are made finer by the sound absorbing material of the perforated chamber to improve the refrigerant distribution performance.

The two-phase refrigerant flow flowing from the pipe 6 flows into the distribution chamber 14 of the distributor and is stirred. At this time, the droplet of the refrigerant flow collides with the wall surfaces of the distribution chamber 14 and the distribution passage 15, and a part of the liquid enters the porous sound absorbing material 13.
At this time, since no shock vibration is generated, the shock vibration is reduced as a result. Further, the large droplets that have entered the porous sound absorbing material 13 flow out of the porous sound absorbing material 13 thereafter. At this time, the droplets are finely divided, so that the droplets are not biased to the respective distribution passages 8 and the distribution performance is improved. The refrigerant flow noise generated in the distribution chamber 14 and the distribution passage 15 is absorbed by the porous sound absorbing material 13.

In the figure, reference numeral 13 'denotes an inward protrusion of the porous sound absorbing material, and reference numeral 21 denotes an orifice formed by the protrusion. Thereby, the distribution chamber is divided into a first distribution chamber 14 and a second distribution chamber 14 '. The other parts are the same as in the first embodiment.

That is, the two-phase refrigerant flow flowing from the pipe 6 flows into the distribution chamber 14 of the distributor and is agitated, and further passes through the orifice to make the droplets finer and flow into the distribution chamber 14 '. Therefore, since the smaller liquid droplets flow into the distribution chamber 14 'than in the first embodiment, the noise is lower,
