《産業上の利用分野》
この考案はリキツドアイス式蓄熱槽に関し、よ

とが開発されている。《Prior art》 For cooling systems for houses, buildings, etc., in order to shift the period of use of electricity as a heat source for cooling from peak electricity demand times (generally during the day) to off-peak times (generally at night), electric power A water heat storage method and an ice heat storage method have been developed, in which cold heat generated by water is stored in water or ice.

このように、これらの方式は冷熱の発生と需要と
に数時間ずれを生じさせ、電力需要の昼夜のアン
バランスの解消を図つている。 These systems consist of a cold heat generating device such as a refrigerator and a cold water heat storage tank or an ice heat storage tank, and generate cold heat using electricity at night, etc., and store this cold heat as cold water or ice in the above heat storage tank. It is then stored and taken out during the day when cold heat is needed and used for cooling the air conditioner.
In this way, these systems create a lag of several hours between the generation and demand of cold heat, and are intended to eliminate the imbalance between day and night power demand.
上記の冷水蓄熱方式と氷蓄熱方式とを比較した
場合、氷の潜熱を利用する後者は、前者と同量の
冷熱を、前者の蓄熱槽よりもはるかに小容量の蓄
熱槽で蓄熱できる利点を有するため、近年、この
氷蓄熱方式が広く利用されている。 When comparing the cold water heat storage method and the ice heat storage method described above, the latter, which uses the latent heat of ice, has the advantage of being able to store the same amount of cold heat as the former in a heat storage tank with a much smaller capacity than the former. Because of this, this ice heat storage method has been widely used in recent years.
この氷蓄熱方式は、氷を製造する立場から、一
般にスタテイツク型とダイナミツク型とに大別さ
れる。 This ice heat storage method is generally classified into static type and dynamic type from the viewpoint of ice production.
スタテイツク型は、氷蓄熱槽内に冷媒流通用コ
イルを設置し、該コイルの周囲に氷を作るもの
で、ソリツドアイス方式とも呼ばれ、機構が単純
であることから、一般に広く採用されている。 The static type is a type in which a refrigerant circulation coil is installed in an ice heat storage tank and ice is created around the coil, and is also called a solid ice type, and is generally widely adopted because of its simple mechanism.
一方、ダイナミツク型は、ハーベスト方式とリ
キツドアイス方式等の新方式が開発され、近年、
実用化に向けて開発活動が活発化している。 On the other hand, new methods such as the harvest method and liquid ice method have been developed for the dynamic type, and in recent years,
Development activities are intensifying toward practical application.
このハーベスト方式とは、製氷板に散水して板
状の氷を作り、これを砕いて破片状氷とし、この
破片状氷を氷蓄熱槽に貯留するものである。 This harvesting method involves sprinkling water on an ice-making plate to create plate-shaped ice, crushing it into fragmented ice, and storing this fragmented ice in an ice heat storage tank.

る。 In addition, the liquid ice method is a method in which water is supercooled by mixing glycol-based antifreeze or other antifreeze with water. Under this condition, the water turns into ice particles, forming a so-called sludge-like structure with a slurry-like fluidity. hold.
《考案が解決しようとする問題点》
前記のスタテイツク型の場合、氷蓄熱槽内に設
置する冷媒流通コイルはコストが高く、特に氷蓄
熱槽が大型化するとイニシヤルコストの面で不利
となり、しかもコイルがあるために槽内清掃が困
難である。<<Problems to be solved by the invention>> In the case of the static type described above, the refrigerant distribution coil installed in the ice heat storage tank is expensive, and especially when the ice heat storage tank becomes large, it becomes disadvantageous in terms of initial cost. Cleaning inside the tank is difficult because of the coil.
これに対し、リキツドアイス方式の場合は、以
上のような問題は無いが、次のような問題があ
る。 On the other hand, the liquid ice method does not have the above problems, but has the following problems.
すなわち、リキツドアイス方式は、例えば第２
図に示すように氷蓄熱槽１から液輸送用ポンプ
（以下、第１のポンプ）３にて製氷機２へ送られ

凍液との混合液Ｌ中の水が過冷却状態となつて氷
粒化し、リキツドアイスＩが生成される。そし
て、このリキツドアイスＩが氷蓄熱槽１へ送ら
れ、貯留される。 In other words, the liquid ice method, for example,
As shown in the figure, a mixed liquid of water and antifreeze (a glycol-based aqueous solution) L is sent from an ice heat storage tank 1 to an ice maker 2 by a liquid transport pump (hereinafter referred to as the first pump) 3 through a flow path 4. While flowing down, the water in the mixture L of water and antifreeze is cooled by the refrigerant (for example, Freon) that is sent and cooled by the refrigerator 5 and flows outside the flow path 4, and the water in the mixture L of water and antifreeze is in a supercooled state. As a result, it turns into ice particles, and Liquid Ice I is produced. Then, this liquid ice I is sent to the ice heat storage tank 1 and stored therein.
このように、従来のリキツドアイス式蓄熱槽

ースが必要であり、また各製氷機毎の断熱が必
要であるため、イニシヤルコストが高くなる。 In this way, in the conventional liquid ice type heat storage tank, the ice making machine 2 that generates liquid ice and the ice heat storage tank 1 that stores the liquid ice are installed separately, so (1) the ice making machine 2 must be insulated. (2) If the ice maker 2 becomes larger, the insulation area will increase and the equipment cost will increase. (3) The installation space for the ice maker 2 and the ice heat storage tank 1 will be required, and additional space will be required. (4) When installing multiple small ice machines 2, each ice machine A vast amount of space is required, including maintenance for each ice maker, and insulation is required for each ice maker, resulting in a high initial cost.
等の問題があつた。There were other problems.
本考案は、上記した問題点に鑑みてなされたも

所要スペースが小さいリキツドアイス式蓄熱槽を
提供することにある。 The present invention was made in view of the above-mentioned problems, and its purpose is to provide a liquid ice type heat storage tank that does not require insulation of the ice maker and requires a small space.

In the tank, one ice maker is built into the ice heat storage tank, a liquid transport pipe connecting the lower part of the ice heat storage tank and the upper part of the ice maker, and the lower part of the ice maker and the upper part of the ice heat storage tank. A pipe for transporting liquid ice was installed to connect the

へ送られる。《Operation》 In this invention, when cold heat is used during the daytime, cold heat is extracted, ice grains melt, and a mixture of water and antifreeze (hereinafter referred to as mixed liquid) stored in the ice heat storage tank is stored in the ice heat storage tank. The ice is extracted into a liquid transport pipe that connects the lower part of the ice storage tank with the upper part of the ice maker built in the ice storage tank, passes through this liquid transport pipe, and is sent to the upper part of the ice maker.

なつて氷粒化し、リキツドアイスとなる。 The mixed liquid sent to the top of the ice maker passes through the mixed liquid flow path inside the ice maker and reaches the bottom of the ice maker, where it is cooled by the refrigerator and cooled by the refrigerant flowing through the refrigerant flow path of the ice maker. , the water in the liquid mixture becomes supercooled and turns into ice particles, forming liquid ice.

The liquid ice is extracted into a pipe for transporting liquid ice that connects the lower part of the ice maker and the upper part of the ice heat storage tank, passes through the pipe for transporting liquid ice, is sent to the upper part of the ice heat storage tank, and is stored in the ice heat storage tank.

効利用が図られる。 Furthermore, at the end of cold heat extraction, mixed liquid and unmelted ice particles are stored in the ice storage tank, so the ice maker built into the ice storage tank is not equipped with special insulation means. However, the mixed liquid and unmelted ice grains create a state of isolation from the outside temperature. In other words, heat loss from the ice maker is absorbed by the ice heat storage tank and used effectively.
