【考案の詳細な説明】 本考案は舶用冷凍ユニツト用凝縮器に関する。[Detailed explanation of the idea] The present invention relates to a condenser for a marine refrigeration unit.
従来のコンテナ舶用冷凍ユニツトに使用してい

うに、冷凍ユニツトの運転中は、冷却水入口管８
から入つた冷却水は水管２内を通り、水路蓋６で
折返し、再度水管２内を通つて冷却水出口管７か

胴１と水管２の間に入り、ここで冷却水により熱
を奪われ、凝縮し冷媒液となつて冷媒液出口管４
から出るようになつている。 In a water-cooled condenser used in a conventional container marine refrigeration unit, as shown in the side view of Fig. 1, during operation of the refrigeration unit, the cooling water inlet pipe 8
The cooling water that entered from the water pipe 2 passes through the water pipe 2, turns around at the water channel cover 6, passes through the water pipe 2 again, and exits from the cooling water outlet pipe 7. On the other hand, the refrigerant gas flows from the refrigerant gas inlet pipe 3 to the shell 1 and the water pipe 2. Here, the cooling water removes heat and condenses to become a refrigerant liquid, which flows into the refrigerant liquid outlet pipe 4.
It's starting to come out.
しかしながら、このような構造の水冷凝縮器に

水冷凝縮器内で冷媒液９が溜まり、冷媒液出口管
４からは冷媒液が出なくなるから、冷凍ユニツト
の蒸発圧力が低下し、冷凍能力が低下したり、甚
だしい場合は、低圧圧力スイツチが動作し冷凍ユ
ニツトが停止するといつた欠点がある。 However, in a water-cooled condenser with such a structure, when the container ship rolls, the refrigeration unit tilts, and as shown in the vertical cross-sectional view of Figure 2, the refrigeration unit tilts.
Refrigerant liquid 9 accumulates in the water-cooled condenser and no refrigerant liquid comes out from the refrigerant liquid outlet pipe 4, so the evaporation pressure of the refrigeration unit decreases, and the refrigeration capacity decreases, or in extreme cases, the low pressure switch is activated. However, the drawback is that the refrigeration unit may stop working.
本考案はこのような事情に鑑みて提案されたも
ので、冷媒封入量が少ない舶用冷凍ユニツトにお
いて、傾斜しても異常なく運転することのできる
凝縮器を提供することを目的とし、筒状胴体の両
端にそれぞれ冷媒液出口管を具えたことを特徴と
する。 The present invention was proposed in view of these circumstances, and aims to provide a condenser for marine refrigeration units with a small amount of refrigerant that can be operated without abnormalities even when tilted. A refrigerant liquid outlet pipe is provided at each end of the refrigerant.
本考案の一実施例を図面について説明すると、
第３図はその側面図、第４図は冷凍ユニツトが傾
いた場合を示す縦断面図である。 An embodiment of the present invention will be explained with reference to the drawings.
FIG. 3 is a side view thereof, and FIG. 4 is a longitudinal sectional view showing the case where the refrigeration unit is tilted.
上図において、１１は胴、１２は水管、１３は

１８は冷却水入口管、１９は冷媒液である。 In the above figure, 11 is a body, 12 is a water pipe, 13 is a refrigerant gas inlet pipe, 14 and 14b are respectively refrigerant liquid outlet pipes provided at both ends of the body 11, 15 and 16 are each a water channel cover, and 17 is a cooling water outlet. tube,
18 is a cooling water inlet pipe, and 19 is a refrigerant liquid.
このような構造において、冷凍ユニツトが運転
中は、冷却水入口管１８から入つた冷却水は、水
管１２→水路蓋１６→水管１２と流れ、冷媒ガス
の熱を奪い冷却水出口管１７から流れ出る。 In such a structure, while the refrigeration unit is in operation, the cooling water that enters from the cooling water inlet pipe 18 flows from the water pipe 12 → the waterway cover 16 → the water pipe 12, removes heat from the refrigerant gas, and flows out from the cooling water outlet pipe 17. .
一方、冷媒ガス入口管１３から胴１１と水管１

び１４ｂから冷媒液となつて出る。 On the other hand, from the refrigerant gas inlet pipe 13 to the body 11 and the water pipe 1
The hot refrigerant gas that has entered the space between the water pipes 12
heat is removed from the refrigerant, condenses, and exits as a refrigerant liquid from the refrigerant liquid outlet pipes 14a and 14b.
次に、コンテナ船がローリングした場合は、冷

い。 Next, if the container ship rolls, the refrigeration unit will tilt and the condenser will also tilt as shown in Figure 4, but the refrigerant will come out smoothly from the refrigerant liquid outlet pipe 14b, so the refrigeration capacity will decrease or the refrigeration There are no problems such as the unit stopping.
また、第４図と反対方向に傾斜した場合は、冷
媒液出口管１４ａから冷媒液がスムーズに出るこ
とができる。 In addition, when it is tilted in the opposite direction to that shown in FIG. 4, the refrigerant liquid can smoothly exit from the refrigerant liquid outlet pipe 14a.
このような構造によれば、コンテナ船がローリ
ングするときは、冷凍ユニツトが傾き、水冷凝縮

トが停止するといつた不具合は発生しない。 According to this structure, when the container ship rolls, the refrigeration unit tilts and the water-cooled condenser also tilts, but no matter which direction the container ship tilts, the refrigerant liquid exits smoothly from the refrigerant liquid outlet pipe 14a or 14b. As a result, problems such as a reduction in refrigerating capacity or, in extreme cases, a low pressure switch operating and stopping the refrigerating unit, do not occur.

冷凍ユニツト用凝縮器を得るから、本考案は産業
上極めて有益なものである。 In short, according to the present invention, by providing refrigerant liquid outlet pipes at both ends of the cylindrical body, it is possible to obtain a condenser for a marine refrigeration unit that does not interfere with the operation of the refrigeration unit even if it is tilted. The invention is extremely useful for industry.
