The outdoor heat exchanger of such an air conditioner has a high heat exchange efficiency. Connect multiple refrigerant tubes in parallel for the purpose of improvement,
It is located in the ventilation path.

均一な熱交換を図っている。In this outdoor heat exchanger, first, the refrigerant flowing in the leeward side refrigerant passage is flowed in the middle to the leeward side refrigerant passage, while the refrigerant flowing in the leeward side refrigerant pipe group is supplied to the leeward side refrigerant passage. There is a type in which the refrigerant is made to flow by intersecting the refrigerant passages so as to flow into the heat exchanger (hereinafter, referred to as a "crossed heat exchanger"). In such a heat exchanger, the heat exchange efficiency of the refrigerant passage on the leeward side is generally high, and the heat exchange efficiency of the refrigerant passage on the leeward side is low. Are made to flow equally, and the refrigerant passages are crossed on the way, so that the refrigerant flows evenly upstream and downstream to achieve uniform heat exchange of the refrigerant.

ないという問題点がある。However, in the above-mentioned conventional cross-type heat exchanger, in order to make the heat exchange of the refrigerant uniform, the number of pipes on the upstream and downstream sides in one refrigerant passage is required. Must be the same, there is a problem that the heat exchanger cannot be easily downsized due to restrictions on the design of the heat exchanger.

を必要とすることになる。In the case of a heat exchanger which is not a cross type but is simply arranged in parallel on the leeward and leeward sides (hereinafter referred to as "parallel type heat exchanger"), heat is generated on the leeward and leeward sides. Since the exchange efficiency is different, it is necessary to flow a different flow rate through each refrigerant passage. However, it is difficult to adjust the flow rate, and an expensive device is required.

Is done. The refrigerant introduced by the refrigerant introduction pipe 22a is supplied to the upstream of the heat exchanger 11 of the outdoor unit by the distribution pipe 25a, and the upstream refrigerant passage 21c.
In the upper stage, the distribution pipe 25b distributes the refrigerant to the leeward refrigerant passage 21a and the leeward refrigerant passage 21b. Then, the refrigerant introduced into each passage passes through the leeward (leeward) passage, and then passes through the leeward (leeward) side passage by the cross pipe 23b to pass through the passage 34.
Through the heat exchanger 11 of the outdoor unit.

After moving to the leeward side refrigerant passage at 3b and passing through a total of four stages of leeward side refrigerant pipes 39, it is led out of the heat exchanger through the passage.

熱交換するようにしている。In this case, since the heat exchange rate on the leeward side is generally higher than the heat exchange rate on the leeward side, the refrigerant passage 21d passing through the leeward side passage has a higher heat exchange rate than the refrigerant passage 21c. Will be expensive. Therefore, the refrigerant is transferred to the refrigerant passage 21.
When the refrigerant flows equally to the refrigerant passages 21 and 21d, the heat cannot be exchanged uniformly. However, in this embodiment, the refrigerant amount of the refrigerant passage 21c having a relatively low heat exchange efficiency is reduced by the refrigerant passage 2c.
Since the amount of the refrigerant flowing through 1d is smaller than that of the refrigerant, heat is uniformly exchanged between the refrigerants.

きる。Generally, the refrigerant flowing near the distribution pipe 25a is in a gas-liquid equilibrium state and contains a certain amount of liquid refrigerant. And such a refrigerant of gas-liquid mixture,
As shown in FIG. 7, when flowing through the distribution pipe having a predetermined angle R, the refrigerant pipe connection end 41 formed in an L shape with respect to the introduction pipe connection end 40 flows in a curved manner. A centrifugal force acts on the refrigerant, so that a heavy liquid is pushed outward and a light gas is pushed inside, and a large amount of liquid flows to the windward connection end 29c located in the outward direction of the flow of the refrigerant. A small amount of liquid flows to the leeward connection end 29d. Therefore, by connecting the refrigerant passage 21d to the leeward connection end 29c and connecting the refrigerant passage 21c to the leeward connection end 29d, uniform heat exchange of the refrigerant can be performed.

The angle is set in degrees, and the distribution ratio is 2/5. In FIG. 7, when R is 0, the distribution ratio is 1/2, and the distribution ratio is evenly distributed to the connection ends 29d and 29c. When R is 90 degrees, the liquid refrigerant is distributed only to the connection end 29a. You.

Thereby, the flow rate of the refrigerant flowing through each refrigerant passage can be easily adjusted. Therefore, even when the heat exchange efficiencies of the refrigerant passages are different, uniform heat exchange can be performed, and there is no design restriction, so that the size of the apparatus can be reduced.
