（産業上の利用分野）
本発明は、冷房負荷用に利用される氷蓄熱システムにお
ける過冷却水製造用熱交換器に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heat exchanger for producing supercooled water in an ice heat storage system used for cooling loads.
（従来の技術）
近年、氷蓄熱システムが、従来の水蓄熱システムに替わ
るものとして種々提案されて来ている。(Prior Art) In recent years, various ice heat storage systems have been proposed as an alternative to conventional water heat storage systems.
該氷蓄熱システムは、夜間電力を利用して夜の間に蓄え
た熱エネルギーを昼間の空気調和用等に活用して、省エ
ネルギー化を図ろうとするものであり、水が氷になる時
の凝固熱を利用するものであるため、従来の水の温度変
化だけを利用した水蓄熱システムに比較して、容積当り
の蓄熱能力を飛躍的に向上させることができ、換言すれ
ば、蓄熱スペースを格段に小型化することが可能となる
。The ice heat storage system aims to save energy by using nighttime electricity to store thermal energy for air conditioning during the day. Because it uses heat, it can dramatically improve the heat storage capacity per volume compared to conventional water heat storage systems that only use temperature changes in water. This makes it possible to downsize the device.
しかして、現在の氷蓄熱システムは、生成される氷の性
状により、固体水を利用する、いわゆるソリッドアイス
方式と、流動性を有する粒状（結晶状）の氷を利用する
、いわゆるリキッドアイス方式とに大別されている。Current ice heat storage systems are divided into two types, depending on the nature of the ice produced: the so-called solid ice system, which uses solid water, and the so-called liquid ice system, which uses fluid granular (crystalline) ice. It is broadly divided into
このうち、リキッドアイス方式では、エチレングリコー
ル等の水溶液を使用し、溶液中の水分を凍結させる方法
が一般的であるが、この方法では、氷の析出とともに残
された溶液の濃度が上昇するため、時間の経過とともに
濃度の高い不凍液を凍結させるといった運転な余偽なく
される問題がある。Among these methods, the liquid ice method generally uses an aqueous solution such as ethylene glycol to freeze the water in the solution, but with this method, the concentration of the remaining solution increases as the ice precipitates. However, there is a problem in that the highly concentrated antifreeze solution freezes over time, making it difficult to operate.
よって、結果的に冷凍システムの成績係数は低下し、ま
た、水充填率にも限界を生じる。Therefore, as a result, the coefficient of performance of the refrigeration system decreases, and there is also a limit to the water filling rate.
そこで、被冷却水を０℃以下になるまで冷却して過冷却
状態の水を作り、これを利用して製氷率を高める手段が
提案されている。Therefore, a method has been proposed in which the water to be cooled is cooled to 0° C. or lower to produce supercooled water and this is used to increase the ice making rate.
かかる過冷却水の製造手段としては、特開昭６３−１４
０６３号に開示されたものがある。A means for producing such supercooled water is disclosed in Japanese Patent Application Laid-open No. 63-14.
There is one disclosed in No. 063.
（発明が解決しようとする課題）
この過冷却水製造システムは、被冷却水を過冷却温度に
まで冷却する熱交換器と、過冷却を解消して氷にする装
置と、蓄水槽を備えており、ここで前記熱交換器として
、第５図及び第６図に示すものが開示されている。(Problem to be Solved by the Invention) This supercooled water production system includes a heat exchanger that cools water to be cooled to a supercooling temperature, a device that eliminates supercooling and turns it into ice, and a water storage tank. Here, as the heat exchanger, those shown in FIGS. 5 and 6 are disclosed.
第５図に示したものは二ｍ管型熱交換器であり、第６図
に示したものは、シェルチューブ型熱交換器であるが、
これらには、以下の欠点がある。The one shown in Figure 5 is a 2m tube type heat exchanger, and the one shown in Figure 6 is a shell tube type heat exchanger.
These have the following drawbacks.
■、いずれも、熱交換器内での内側コイル３０が直線状
になっているため、第７図に示すように、コイル３０内
での被冷却水の流れは、中央部の流速が最も速く、管壁
に近くなるにつれて流速が減少するという速度勾配Ｖが
生じ、いわゆる層流域を形成してしまう。In both cases, the inner coil 30 in the heat exchanger is linear, so as shown in Figure 7, the flow rate of the water to be cooled in the coil 30 is fastest in the center. , a velocity gradient V occurs in which the flow velocity decreases as it approaches the pipe wall, forming a so-called laminar region.
よって、図示のような温度勾配′「が発現し、最も低温
となる管壁部分から徐々に氷が成長し、コイル３０内で
結氷してしまう事態となる。As a result, a temperature gradient ``'' as shown in the figure develops, and ice gradually grows from the tube wall portion where the temperature is the lowest, resulting in freezing inside the coil 30.
■、単位交換熱量に対する伝熱面積が大きくなるため、
熱交換器自体を大型化する必要がある。■Because the heat transfer area increases per unit amount of heat exchanged,
It is necessary to increase the size of the heat exchanger itself.
