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 time lag between the generation and demand of cold heat, and aim to eliminate the imbalance between day and night power demand.

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 above-mentioned cold water heat storage method and ice heat storage method, 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 much smaller capacity heat storage tank 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

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

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 an antifreeze such as glycol with water. Under this condition, the water turns into ice particles and becomes a so-called sludge, with a slurry-like fluidity. hold.
《考案が解決しようとする問題点》

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

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. This coil makes it difficult to clean the inside of the tank.
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.

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 (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.

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.

In the tank, a plurality of the ice making machines are built into the ice heat storage tank, and a liquid transport pipe connects the lower part of the ice heat storage tank and the upper part of the ice making machine, and the lower part of the ice making machine and the ice making machine are connected to each other.

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 this 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.

However, the mixed liquid and unmelted ice grains create a state of isolation from the outside temperature. That is, heat loss generated from the ice maker is absorbed by the ice heat storage tank and effectively utilized.
