のである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cooling system, and in particular, the present invention skillfully adapts the large cooling capacity of ice and the low operating cost of water circulation, and utilizes nighttime electricity. This invention relates to a cooling device that can store ice.
（従来の技術）
住宅、ビル等の冷房及び除湿を行う冷房方式において、
従来は冷水又は氷により冷熱を蓄積し、この冷熱を冷水
として取出し、冷房機や熱交換器等の冷房負荷に冷水を
循環させる方式がある。(Prior art) In a cooling system that cools and dehumidifies houses, buildings, etc.,
Conventionally, there is a method of accumulating cold energy using cold water or ice, extracting this cold energy as cold water, and circulating the cold water to a cooling load such as an air conditioner or a heat exchanger.
しかし、この方式では、例えば第４図に示すように、氷
蓄熱槽１からポンプ２を介して冷房負荷３に至る間に、
５〜６℃の冷水が７℃程度に昇温しでしまう。However, in this system, as shown in FIG.
Cold water at 5 to 6 degrees Celsius ends up heating up to about 7 degrees Celsius.
この冷水が、冷房負荷３で冷房利用に付され、１２℃程
度まで昇温して氷蓄熱槽１に循環される。This cold water is used for cooling with a cooling load 3, heated to about 12° C., and circulated to the ice heat storage tank 1.
従って、冷房負荷３での冷熱利用温度差は５℃程度であ
り、冷房能力は低い。Therefore, the temperature difference in cooling heat usage at cooling load 3 is about 5° C., and the cooling capacity is low.
この方式で、冷房負荷３の冷却能力を高めるためには、
冷房負荷３内は勿論、氷蓄熱槽１から冷房負荷３．冷房
負荷３から氷蓄熱槽１に至る配管を大径のものとし、か
つポンプ２の能力及び動力を大きくして、大容量の冷水
を循環させる必要がある。In order to increase the cooling capacity of cooling load 3 using this method,
Not only inside the cooling load 3, but also from the ice heat storage tank 1 to the cooling load 3. It is necessary to make the piping from the cooling load 3 to the ice heat storage tank 1 large in diameter, and to increase the capacity and power of the pump 2 to circulate a large volume of cold water.
そこで、最近、上記の方式に代えて、リキッドアイス（
氷粒と水とのシャーベット状混合体）により冷熱を蓄積
し、このリキッドアイスを直接冷房負荷に循環させる方
式が注目されて来ている。Therefore, recently, instead of the above method, liquid ice (
A method that accumulates cold energy using a sherbet-like mixture of ice particles and water and circulates this liquid ice directly to the cooling load is attracting attention.
この方式では、リキッドアイス中の氷粒が潜熱を有する
ため、上述の冷水を循環させる方式に比し、冷却能力が
高く、冷房負荷内はもとより、氷蓄熱槽から冷房負荷、
冷房負荷から氷蓄熱槽に至る配管を細径のものとするこ
とができるばかりでなく、これらの配管に設置するポン
プも小能力。In this method, since the ice particles in the liquid ice have latent heat, the cooling capacity is higher than the above-mentioned method of circulating cold water, and the cooling capacity is higher than that of the above-mentioned method of circulating cold water.
Not only can the piping from the cooling load to the ice storage tank be made smaller in diameter, but the pumps installed in these piping can also be of smaller capacity.
小動力のものとすることができる。It can be of small power.
（発明が解決しようとする課題）
しかし、上記のリキッドアイスを直接冷房負荷に循環さ
せる方式においては、■極く低温のリキッドアイスに耐
える高価な材質の配管が必要であること、■リキッドア
イス中の氷粒が配管の内部や、配管の接続部等で詰まり
、冷却能力を低下させたり、時には装置を停止させる事
故を起こすことがあること、■冷房負荷の負荷変動に即
応できないこと等の問題がある。(Problems to be Solved by the Invention) However, in the above method of circulating liquid ice directly to the cooling load, ■ it is necessary to use piping made of expensive material that can withstand extremely low temperature liquid ice; Problems include the fact that ice particles can clog the inside of piping or piping connections, reducing cooling capacity and sometimes causing accidents that cause equipment to stop; ■ Problems such as not being able to respond quickly to changes in the cooling load. There is.
このような問題を解決するために、本出願人は、先に、
第３図に示すような、水蓄熱槽又は製氷機１と冷房負荷
３の間に解氷タンク４（解放型）。In order to solve such problems, the applicant first
As shown in FIG. 3, there is an ice melting tank 4 (open type) between the water heat storage tank or the ice maker 1 and the cooling load 3.

１８２９号）。4' (closed type) is provided, and the flow control valve 10 is operated by the detection signals of the temperature sensor 13 and flow rate detector 12, and an appropriate amount of hot water at the outlet of the cooling load 3 is sent to the deicing tank 4°4'. The ice grains in tanks 4 and 4' are thawed and only water is used for cooling load 3.
proposed a cooling system that would send air to
No. 1829).

電力を利用して製氷し蓄氷を行うという氷蓄熱方式の利
点が損われる懸念がある。In the cooling system proposed in the future, although the above-mentioned conventional spacing point can be solved, the remainder of the hot water at the outlet of the cooling load 3 is constantly returned to the ice heat storage tank or the ice making machine 1. This hot water gradually dissipates the cold heat inside the ice storage tank or ice maker 1, and in some cases (if the ice maker is set to start operating when the temperature inside the ice storage tank or ice maker 1 exceeds a predetermined value), it may occur during the daytime. However, there are concerns that the ice maker will start operating and the advantages of the ice thermal storage method, which uses electricity during the night to make and store ice, will be lost.

微細氷粒を解氷するために使用される。This water or liquid ice containing ice chips is thawed in this ice water heat storage tank, and only cold water is sent to a cooling load such as an air conditioner or a heat exchanger via a sub pump and sub piping. The cold water whose temperature has been raised by the cooling load is returned to the ice water heat storage tank through the sub-piping and is used to melt the pieces of water or the fine ice particles in the liquid ice.

No clogging of ice particles occurs within the cooling load. Moreover, the temperature from the ice storage tank or ice water mixing device to the ice water heat storage tank is maintained at approximately 0° C. because the cold water contains ice chips and the like. If the distance between the ice water heat storage tank and the cooling load is shortened, the temperature difference in cold heat usage can be increased, improving efficiency.

、２次側では氷の潜熱と、顕熱とが利用でき、冷熱利用
温度差が大きくなる。(Effects of the Invention) As described above, in the cooling device according to the present invention, water containing ice chips or liquid ice is sent to the so-called secondary side of the cooling load, so the latent heat and sensible heat of the ice are utilized on the secondary side.

配管は例えば２℃程度の冷水に耐えるものであればよく
、高コストの管材でなくても充分である。しかも、氷片
等が配管内で詰まるおそれもない。Further, since cold water is circulated to the cooling load, the piping within the cooling load only needs to be able to withstand cold water of, for example, about 2° C., and does not need to be made of high-cost pipe material. Furthermore, there is no risk of ice chips or the like clogging the pipes.

駄がなくなり、負荷変動に効果的に対応できる。Furthermore, even if the cooling load becomes large, water containing ice chips or liquid ice with a large cooling capacity is sent to the secondary side, so it can quickly respond to this large load, and when the load is small, a small amount of ice is sent to the secondary side. Since chilled water can be sent to the cooling load, there is no wasted pump power and it is possible to effectively respond to load fluctuations.
