(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
ける蓄氷放熱槽の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to the structure of an ice storage and heat dissipation tank 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
るものとして秤々提案されて来ている。(Prior Art) In recent years, ice heat storage systems have been proposed extensively as an alternative to conventional water heat storage systems.
該氷蓄熱システムは、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。Since this ice heat storage system utilizes the heat of solidification when water turns into ice, it dramatically increases the heat storage capacity per volume compared to conventional water heat storage systems that only use temperature changes in water. In other words, it is possible to significantly reduce the size of the heat storage space.
しかして、従来の氷蓄熱システムにおける蓄氷槽を中心
とした構成は、例えば実開昭63−14063号に開示
されており、第3図に示す夜間の製氷時と、第4図に示
す昼間運転時とでは、作動系統が異なっている。The configuration of a conventional ice heat storage system centered on an ice storage tank is disclosed, for example, in Japanese Utility Model Application Publication No. 14063/1983. The operating system is different during operation.
即ち、夜間製氷時には、冷凍機30を運転してブライン
の温度を所定温度まで下げて熱交換器31内に送り込み
、一方、蓄氷槽32の底部から引き抜かれた被冷却水を
熱交換器31に送給して、前記ブラインにより0℃以下
の過冷却水にして、蓄氷槽32の上部まで移送し、放出
管33から落下させ、落下時の衝撃により過冷却水を氷
結させ、シャーベット状の氷を生成してゆき、所定の充
填率となるまで、蓄氷槽32内に貯溜する。That is, when making ice at night, the refrigerator 30 is operated to lower the temperature of brine to a predetermined temperature and the brine is fed into the heat exchanger 31, while the water to be cooled drawn from the bottom of the ice storage tank 32 is transferred to the heat exchanger 31. The supercooled water is turned into supercooled water of 0°C or less by the brine, and then transferred to the upper part of the ice storage tank 32 and dropped from the discharge pipe 33. The supercooled water is frozen by the impact of the fall, and becomes a sherbet-like water. ice is generated and stored in the ice storage tank 32 until a predetermined filling rate is reached.
他方、昼間の運転時(解氷時)には、蓄氷槽32の底部
から引き抜いた0℃付近の水を空調器34等の冷房負荷
に送り込む。On the other hand, during daytime operation (melting ice), water at around 0° C. drawn from the bottom of the ice storage tank 32 is sent to the cooling load such as the air conditioner 34.
また、空調器34から熱交換器31を経由した二次側返
水を、蓄氷槽32の上部から落下させ。Further, the secondary return water from the air conditioner 34 via the heat exchanger 31 is dropped from the upper part of the ice storage tank 32.
回転レーキ装置35を介して蓄氷槽32内に散水するこ
とにより、槽内の氷を融解するようになっている。By sprinkling water into the ice storage tank 32 via the rotating rake device 35, the ice in the tank is melted.
(発明が解決しようとする課題)
しかしながら、かかるシステムでは、昼間運転時に蓄氷
槽32内の氷が冷房負荷に対して極端に不足し、新たに
氷を生成しなければならなくなった時でも、空調器34
からの戻り水は、12℃程度にまでなっており、この温
度の戻り水を熱交換器31で一気に過冷却水とするのは
不可能となる。(Problem to be Solved by the Invention) However, in such a system, even when the ice in the ice storage tank 32 becomes extremely insufficient for the cooling load during daytime operation and new ice must be generated, Air conditioner 34
The temperature of the return water is about 12° C., and it is impossible to convert the return water at this temperature into supercooled water at once in the heat exchanger 31.
よって、昼間に製氷の必要があるときは、−時空調機3
4の運転を中止して製氷を行なうしかないという欠点が
ある。Therefore, when it is necessary to make ice during the day, -time air conditioner 3
There is a disadvantage that the operation of Step 4 must be stopped to make ice.
また、昼間運転時においては、i記した如く蓄氷槽32
内に散水することにより、槽内の氷を融解するようにな
っており、二次返水の温度は、相当程度上昇しているか
ら、氷の溶解が必要以上に急激に行なわれ、無駄な熱損
失により氷が不足する事態になり易いという問題を有し
ている。In addition, during daytime operation, the ice storage tank 32
The ice in the tank is melted by sprinkling water inside the tank, and since the temperature of the secondary return water has risen considerably, the ice melts more rapidly than necessary, resulting in wasted waste. There is a problem in that ice tends to run out due to heat loss.

解消槽4へと送給される。At the same time, O2 is supplied from the lower part of the ice storage tank 2 via the return pipe 17.
The water to be cooled at a temperature of about ℃ flows into the heat exchanger I3, and heat exchanges with the refrigerant or brine, resulting in a temperature of -2℃ to
It is supercooled to about -3° C. and is fed from the feed pipe 18 to the supercooling elimination tank 4.
本実施例に係る過冷却解消槽4には、例えば第2図に示

。Thereafter, using the ice crystals as seed water, the supercooled water that descends on the supercooled water descending surface 19 and is sequentially supplied comes into contact with the seed water and is continuously produced as a sherbet-like ice slurry S. Teyuki, the previously generated ice slurry S
is gradually pressed by the ice slurry S that will be generated later, and slowly rises on the ice delivery surface 20 toward the tip 20a, and from the tip 20a, the wall surface of the ice storage tank 2 due to its own weight. The ice slowly descends along the ice storage tank 2 and is stored in the ice storage tank 2 without giving any impact.
このようにして過冷却水の顕熱分は、氷スラリーSの潜
