を（り返し行う冷凍サイクルを構成する。Next, the operation will be explained. The high temperature and high pressure gas refrigerant compressed and discharged by the compressor (1) is transferred to the outdoor heat exchanger (2).
While passing through the refrigerant, it exchanges heat with outdoor air and condenses into a high-pressure liquid refrigerant. Then, as it passes through the decompression capillary (3), it is rapidly decompressed and expands, becoming a low-pressure gas-liquid two-phase refrigerant 9
The refrigerant is distributed by the distributor (7) and the distribution pipe (8) and sent to each refrigerant flow path of the indoor heat exchanger (4), where it evaporates and becomes a low-pressure gas refrigerant by exchanging heat with the indoor air. This low pressure gas refrigerant passes through the accumulator (5) and the compressor (
1), is compressed again, and is discharged, forming a refrigeration cycle in which the same operation as described above is performed (repeatedly).

のである。In this refrigeration cycle, one distributor (7) first constricts the low-pressure gas-liquid two-phase refrigerant through an orifice (9) and then flows it into the gas-liquid mixing chamber (11) in order to evenly distribute the low-pressure gas-liquid two-phase refrigerant without causing any drift in the liquid part. The gas and liquid parts of the gas-liquid two-phase refrigerant are discharged, mixed uniformly, and led out to the distribution pipe (8) for uniform distribution.

題点があった。Conventional distributors are configured with two or more units, so when the air conditioner is started, gas-liquid two-phase refrigerant containing a large amount of gas refrigerant is temporarily supplied to the distributor, so the gas refrigerant in the droplets is There is a problem in that when passing through an orifice, the bubbles rapidly expand and become so-called cavitation bubbles that flow into the mixing chamber, colliding with the wall surface of the mixing chamber and bursting, producing an impact sound.
二の発明は上記のような問題を解消するためになされた
ものであり、空調機の始動時にも、冷媒の衝撃音を発生
しない静粛なる分配器を得ることを目的とする。The second invention was made to solve the above-mentioned problems, and aims to provide a quiet distributor that does not generate refrigerant impact noise even when an air conditioner is started.

At the outlet of (10), a first gas-liquid mixing chamber (11), a wire mesh (12) which is a particle refining means, and a second gas-liquid mixing chamber (13) are arranged, and a gas-liquid two-phase mixture is provided. Mixing is promoted and the mixture is sent to the evaporator (I4) through the distribution pipe (8) connected to the distribution hole (I5).
なお 冷凍サイクルの構成は従来例と同様であるので説
明は省略する。Note that the configuration of the refrigeration cycle is the same as that of the conventional example, so a description thereof will be omitted.

各流路に送られる。The operation of the refrigeration cycle is the same as the conventional one, so its explanation will be omitted. In Fig. 1, which explains the function of the two-distributor, gas-liquid two-phase refrigerant is transferred from the refrigerant pipe (6) to the conical cone in the distributor (7). into the shaped orifice (9). The conical orifice prevents a sudden pressure drop by gradually increasing the flow rate of the gas-liquid two-phase refrigerant.
A flat plate orifice (10) is arranged at the outlet of the gas-liquid mixing chamber (11), where the flow velocity is set to the maximum value and the difference between the flow velocity of the gas part and the liquid part of the gas-liquid two-phase refrigerant is set to the minimum value. The gas and liquid are mixed by being diffused by sending the gas to the air. Furthermore, the relatively thick droplets of "I" are finely divided by a wire mesh (12) and sent to the second gas-liquid mixing chamber (13). A distribution pipe (8) connected to the distribution hole (15) distributes the liquid evenly and sends it to each channel of the evaporator (14).
以トが分配作用についての説明であるがさらに冷媒気泡

内を比較的自由に伝播するためである。The impact noise caused by refrigerant bubbles is mainly generated when the refrigeration cycle starts.At a point where the pressure suddenly drops, the refrigerant begins to evaporate rapidly, forming and growing bubbles.When the bubbles hit the wall and burst, the impact noise is generated. It becomes and spreads. This is the impact sound caused by the bursting of so-called cavitation bubbles. Regarding the distributor, cavitation bubbles are generated Qg during the pressure drop in the rapidly decreasing flow when passing through the orifice, grow, and when they hit the wall surface of the gas-liquid mixing chamber and burst, an impact sound is produced. The more liquid refrigerant there is in the surrounding area, the greater the damping effect of the liquid, and the smaller the impact sound becomes. The reason why a loud noise is generated when the refrigeration cycle is started is because there is little liquid refrigerant in the surrounding area, and the impact noise caused by the bursting of bubbles in the droplets propagates relatively freely within the gas-liquid mixing chamber.

判明した。In order to reduce the impact noise mentioned above at the time of starting such a refrigeration cycle, the plate thickness of the flat plate orifice and the length of the gas-liquid mixing chamber in the flow direction are changed to reduce the impact noise from 5XIIZ, which is the main component of the sound at the time of start-up. Figure 3 shows the results of actual measurements of overall noise values. In Figure 2, Ql, σ,
