(産業上の利用分野)
本発明はビルの空調冷房、食品貯蔵等に使用する氷蓄熱
装置用の製氷装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an ice making device for an ice heat storage device used for air conditioning and cooling of buildings, food storage, and the like.
(従来の技術)

製氷蓄熱を行い、昼間の高電力コスト時に解氷して冷熱

ため、従来の水の顕熱を利用した氷蓄熱装置に対して、
蓄熱槽の大幅な小型化が可能なため、最近急速に普及が
行われている。(Conventional technology) An ice heat storage device uses cheap late-night electricity to operate a refrigerator to store ice and then melts the ice during the day when electricity costs are high to utilize the cold energy, which utilizes the latent heat of solidification of water. Because of its heat storage method, compared to the conventional ice heat storage device that uses the sensible heat of water,
Since heat storage tanks can be significantly downsized, they have recently become popular.

激な熱負荷変動への対応ができないという問題点があっ
た。Conventionally, this type of ice-making equipment for ice heat storage has been designed to flow low-temperature refrigerant or antifreeze to the -blade side of the ice-making heat exchanger tube (heat exchanger), and flow water to the other side to directly contact the surface of the heat exchanger tube. The fixed ice-making method is widely adopted because the equipment cost is low, but this method requires large equipment because the thermal resistance of the heat transfer surface increases as the ice layer grows, reducing the ice-making capacity. Moreover, due to the fixed ice, the thermal response during ice melting is poor, making it impossible to respond to sudden changes in heat load.
これに対して、最近、流動状の氷を製造する方法が提案

が良好で、製氷コストが安いと言う長所を有している。In response to this, a method for producing fluid ice has recently been proposed. For example, as shown in Figure 5, on page 77 of the November 17, 1986 issue of Nikkei Mechanical, there is A falling water film method uses a fluorocarbon liquid refrigerant on the outside of the heat transfer tube of a tube heat exchanger, and water overflows and falls onto the vertical surface inside the heat transfer tube to produce very thin sherbet-like (fluid) ice. It has been proposed and is publicly known that, unlike the conventional fixed ice making method, there is no deterioration in ice making capacity over time because it makes fluid ice, and the heat storage tank is filled with water to store heat in this fluid ice. It has the advantages of high efficiency, good thermal response during ice thawing, and low ice making cost.

冷却(伝熱)にムラか生じて伝熱管に着氷が発生するた
め、流動状の製氷か停止しやすく連続運転が困難という
問題点かあった。(Problem to be Solved by the Invention) However, since this ice-making device uses a shell-and-tube system consisting of a heat exchanger or a large number of small-diameter heat exchanger tubes, the upper end of each heat exchanger tube is at the same level. This results in uneven water overflow and fall.
Since cooling (heat transfer) is uneven and ice builds up on the heat exchanger tubes, there was a problem that the ice making was in a fluid state and it was easy to stop, making continuous operation difficult.
本発明の目的は、上述の問題点である伝熱管への着氷防

By forming this, ice formation on the heat transfer tubes can be suppressed and fluid ice can be made continuously.
さらに、噴射ノズルからの高速製氷水で間欠的に伝熱管
の洗浄を行うため、管内壁面への氷やゴミの付着が無い
。Furthermore, since the heat transfer tubes are intermittently cleaned with high-speed ice-making water from the injection nozzle, there is no adhesion of ice or dirt to the inner wall surfaces of the tubes.

FIG.
竪型の二重管式熱交換器の伝熱管1は高熱伝導性・気密
性・耐蝕性等の機能が要求されるため、通常、ステンレ
ス鋼・アルミ等の金属管を使用する。The heat transfer tubes 1 of the vertical double tube heat exchanger are required to have functions such as high thermal conductivity, airtightness, and corrosion resistance, and therefore metal tubes such as stainless steel or aluminum are usually used.

の外表面に保温材を施工したものを使用する。On the other hand, the outer shell tube 2 of the heat exchanger, which is provided to cover the outer periphery of the heat exchanger tube 1, is usually made of the same material as the heat exchanger tube 1 because it is required to have functions such as heat insulation, airtightness, and corrosion resistance. Use a heat insulating material on its outer surface.

This makes it possible to further improve the icing prevention effect.
噴霧ノズル4は、通常、水滴径が100〇−以下の低圧
噴霧ノズルを使用し、伝熱管への着氷防止のだめの空気
泡の随伴とポンプ昇圧によるエネルギーロスの軽減を図
る。The spray nozzle 4 is usually a low-pressure spray nozzle with a water droplet diameter of 1000 mm or less to reduce entrainment of air bubbles to prevent icing on the heat transfer tubes and energy loss due to pump pressure increase.
噴射ノズル5は管1壁面の洗浄および付着水の剥離が必

た時点て製氷水3の間欠噴射を行うか、管壁着氷の防止

射を行う方が良い。Since the injection nozzle 5 needs to clean the wall surface of the tube 1 and remove the adhering water, a high-pressure injection nozzle that can secure a certain amount of collision energy on the wall surface of the tube 1 is used, and when the amount of heat transfer in the heat exchanger decreases, the ice-making water is removed. It is better to perform intermittent injection as shown in step 3, or to perform intermittent injection periodically at fixed intervals in order to more reliably prevent pipe wall icing.
なお、伝熱管1の管径が大きい場合は、伝熱管1の円周
方向の管壁面に近接して複数の噴射ノズル5を設ける。Note that when the tube diameter of the heat exchanger tube 1 is large, a plurality of injection nozzles 5 are provided close to the tube wall surface of the heat exchanger tube 1 in the circumferential direction.

勿論可能である。Coolant 7 completed between heat exchanger tube 1 and outer shell tube 2 of heat exchanger
Normally, antifreeze is used and heat is exchanged with the refrigerant in the refrigeration circuit (not shown in the diagram) using an indirect heat exchanger to cool it to below 0°C and circulated, but it is not possible to use the refrigerant in the refrigeration circuit directly. Of course, it is also possible.
また、本実施例は製氷水3と冷却液7の熱交換が向流の
ケースであるが、冷却液7を熱交換器の上部側から供給
して熱交換を並流とすることも勿論可能である。Furthermore, although this embodiment is a case in which the heat exchange between the ice-making water 3 and the cooling liquid 7 is in countercurrent flow, it is of course also possible to supply the cooling liquid 7 from the upper side of the heat exchanger to perform heat exchange in parallel flow.

A pump 9a is provided in this pipe 8a to continuously supply ice-making water 3 to the spray nozzle 4.
噴霧ノズル4より供給された製氷水3は伝熱管1の上方
で均一な水膜10となり、冷却液7で冷却されて流動状
の氷11が製造される。The ice-making water 3 supplied from the spray nozzle 4 forms a uniform water film 10 above the heat transfer tube 1, and is cooled by the cooling liquid 7 to produce fluid ice 11.
また、蓄熱槽6の下部と噴射ノズル5を水配管8bで接
続し、この配管8bにポンプ9bを設けて、間欠的に高
速の製氷水3を伝熱管1に噴射して管内壁面の洗浄と着
氷の防止を行う。In addition, the lower part of the heat storage tank 6 and the injection nozzle 5 are connected by a water pipe 8b, and a pump 9b is installed in this pipe 8b to intermittently inject high-speed ice-making water 3 into the heat transfer tube 1 to clean the inner wall surface of the pipe. Prevent icing.
図中の矢線は製氷水3および冷却液7の流動方向を示す

この落下水膜10は伝熱管1を流下中に冷却液7て間接
冷却されて過冷却状態の水となり、落下水膜10の乱流
作用でこの過冷却状態が破壊され、過冷却水の顕熱に相
当した流動状の氷11が製造される。This falling water film 10 is indirectly cooled by the cooling liquid 7 while flowing down the heat transfer tube 1, and becomes supercooled water.The turbulence of the falling water film 10 destroys this supercooled state, and the supercooled water becomes visible. Fluid ice 11 corresponding to heat is produced.
この流動状の水11は、噴霧水の気泡随伴作用で氷結品
間に空気隔膜が形成されるため、通常、水径か200如
以下の微細な流動状の氷ができる。In this fluid water 11, air diaphragms are formed between the frozen products due to the bubble-associated action of the sprayed water, so that fine fluid ice with a water diameter of about 200 mm or less is usually formed.

に着氷が発生するため、この場合は、第1図の伝熱管1
の上方側を非冷却構造とした第4図の製氷装置とする。In addition, if the amount of ice-making water 3 from the spray nozzle 4 is small,
In this case, the cooling of the collision part of the spray water is too strong and ice builds up on the tube wall surface near the collision part.
The ice-making apparatus shown in FIG. 4 has a non-cooling structure on the upper side.
また、本実施例は製氷装置の熱交換器構造が最も簡単な
二重管式のケースであったが、伝熱管が多管構造のシェ
ル・アンド・チューブ式とすることも勿論可能である。Further, in this embodiment, the heat exchanger structure of the ice making apparatus is a double-tube type, which is the simplest structure, but it is of course possible to use a shell-and-tube type heat exchanger with a multi-tube structure.
