７内を夫々設定温度に冷却する。 Next, the operation of the above configuration will be explained. When the refrigerator is in operation, the refrigerant discharged from the discharge port 11a of the compressor 11 flows through the daily delivery tube 19, the evaporation tube section 14, the back tube section 15, and the connection tube section 20 as shown by arrows in FIG. 2 for convenience. - Condensing pipe section 12 - Anti-condensation pipe section 16, 17 - Dryer 21 - Capillary tube 22 - Refrigerator room cooler 3a - Freezer room cooler 4
- The compressor 1 is passed through the suction pipe 23 in order.
1, the circulation operation is repeated, the heat dissipation tube 18 radiates heat, and the refrigerator compartment cooler 3a and the freezer compartment cooler 4 bring the inside of the refrigerator compartment 6 and the freezer compartment 7 to the set temperature, respectively. Cooling.
ところで、上述したような冷凍サイクルの放熱
管１８においては、冷媒は蒸発管部１４、背部管
部１５及び凝縮管部１２を順次流通するに従つて
次第に液化され、防露管部１６，１７を流通した
後は略全てが液化した状態となるものである。
今、かりに凝縮管部１２と防露管部１６，１７と

すると、冷媒は液体になつているため重力に抗し

管部１７から凝縮管部１２へ流通する冷媒の流動
状態が悪くなり、冷媒の循環効率が大幅に悪化
し、冷却性能が著しく低下してしまう問題があ
る。 By the way, in the heat dissipation tube 18 of the refrigeration cycle as described above, the refrigerant is gradually liquefied as it passes through the evaporation tube section 14, the back tube section 15, and the condensation tube section 12 in sequence, and the refrigerant passes through the dew prevention tube sections 16 and 17. After being distributed, almost all of it is in a liquefied state.
Now, if the piping is arranged so that the refrigerant flow order between the condensing pipe section 12 and the anti-condensation pipe sections 16 and 17 is reversed, the refrigerant is in a liquid state, so it will move against gravity to the upper condensing pipe section 12. Therefore, the flow state of the refrigerant flowing from the dew prevention tube section 17 to the condensing tube section 12 deteriorates, and there is a problem that the circulation efficiency of the refrigerant is significantly deteriorated and the cooling performance is significantly reduced.

いえども冷媒の液化が進行して凝縮管部１２は大
量の熱を放出するので、機械室９内の温度が著し
く上昇し、圧縮機１１の駆動モータが加熱状態に
なつてその効率が悪くなつてしまう虞れがある。
さらには、冷媒が圧縮機１１の比較的径少な吐出
口１１ａから凝縮管部１２に直列噴出するため、
この際に脈動が生じ易く、振動発生の原因となる
難がある。 Here, the back pipe part 15 and the dew prevention pipe part 16 are connected and connected, and the condensing pipe part 12 is connected to the discharge port 11 of the compressor 11.
connected between a and daily life tube 19,
It may be possible to try to solve the problem of circulation efficiency as described above, but if this is done, the refrigerant discharged from the compressor 11 to the condensing pipe section 12 will be
Partly because the machine room 9 is at a relatively high temperature, it is difficult to liquefy and the amount of liquefaction is small, making it more like a gas, which again has the disadvantage of reducing the efficiency of liquid circulation. In addition, even if the amount of refrigerant liquefied is small at this time, the liquefaction of the refrigerant progresses and the condensing pipe section 12 releases a large amount of heat, so the temperature in the machine room 9 rises significantly, and the drive motor of the compressor 11 There is a risk that the fuel will become overheated and its efficiency will deteriorate.
Furthermore, since the refrigerant is injected in series from the relatively small diameter discharge port 11a of the compressor 11 to the condensing pipe section 12,
At this time, pulsation is likely to occur, which may cause vibrations.

冷媒の噴出によつて振動することもない。 On the other hand, according to the configuration of the present embodiment described above, the evaporation tube section 14, the back tube section 15, the condensation tube section 12
Since the dew-proof pipe parts 16 and 17 are piped in this order so that the refrigerant flows, the condensation pipe part 12
The refrigerant flowing through becomes a gas-liquid mixture, and then flows down into the dew prevention pipe portions 16 and 17 located below with the help of gravity. Therefore, the flow state of the refrigerant flowing from the condensing pipe section 12 through the dew prevention pipe section 16 becomes smooth, and the circulation efficiency of the refrigerant increases as a whole, thereby improving the cooling performance. Moreover, the evaporation tube section 1 is provided in the condensation tube section 12.
Since the refrigerant that has been liquefied to a certain extent flows through the condensing pipe section 12 and the back pipe section 15, the amount of heat dissipated in the condensing pipe section 12 is not so large. The drive motor does not become heated, and the condensing pipe section 12 does not vibrate due to the jetting of refrigerant.
