Description

本発明は、二流体ミストノズルを備えた冷却装置に関する。   The present invention relates to a cooling device including a two-fluid mist nozzle.

従来、この種の冷却装置は、水を空気によって微細化する二流体ミストノズルを用いてミストを発生させ、そのミストの気化熱冷却を利用して空間を冷却する。   Conventionally, this type of cooling device generates a mist using a two-fluid mist nozzle that refines water with air and cools the space by using vaporization heat cooling of the mist.

二流体ミストノズルとして、ノズルの内部で水を微細化する内部混合式（例えば特許文献１）と、ノズルの外部で水を微細化する外部混合式（例えば特許文献２）とが知られている。これらは何れも空気の噴流によって水を粉砕して微細化する。   As a two-fluid mist nozzle, an internal mixing type that refines water inside the nozzle (for example, Patent Document 1) and an external mixing type that refines water outside the nozzle (for example, Patent Document 2) are known. . All of them are pulverized by air jets to make them finer.

図３に、特許文献１に記載の内部混合式の二流体ミストノズルの概略を示す。図３に示すように、内部混合式の二流体ミストノズルは、水を供給する水供給経路１０１と、空気を供給する空気供給経路１０２と、水供給経路１０１から供給された水と空気供給経路１０２から供給された空気とを混合する気液混合部１０３と、気液混合部１０３で微細化された水と空気を噴出する噴霧孔１０４と、を備える。   FIG. 3 shows an outline of an internal mixing type two-fluid mist nozzle described in Patent Document 1. As shown in FIG. 3, the internal mixing type two-fluid mist nozzle includes a water supply path 101 for supplying water, an air supply path 102 for supplying air, and water and air supply paths supplied from the water supply path 101. The gas-liquid mixing part 103 which mixes the air supplied from 102, and the spray hole 104 which ejects the water refined | miniaturized by the gas-liquid mixing part 103 and air are provided.

図４に、特許文献２に記載の外部混合式の二流体ミストノズルの概略を示す。図４に示すように、外部混合式の二流体ミストノズルは、水を供給する水供給経路２０１と、空気を供給する空気供給経路２０２と、水供給経路２０１から供給された水を噴出する水噴出孔２０３と、空気供給経路２０２から供給された空気を噴出する空気噴出孔２０４と、ノズル外部に設けられおり噴出した水を噴出した空気で粉砕する気液混合部２０５と、を備える。   FIG. 4 shows an outline of an external mixing type two-fluid mist nozzle described in Patent Document 2. As shown in FIG. 4, the external mixing type two-fluid mist nozzle includes a water supply path 201 that supplies water, an air supply path 202 that supplies air, and water that ejects water supplied from the water supply path 201. An ejection hole 203, an air ejection hole 204 that ejects air supplied from the air supply path 202, and a gas-liquid mixing unit 205 that is provided outside the nozzle and pulverizes the ejected water with the ejected air.

また、二流体ミストノズルには、高圧の空気と水を供給する必要がある。そのために、例えば図５に示すように、コンプレッサとポンプを使用して高圧の空気と水を供給する。図５は、ミストを噴霧する二流体ミストノズル３０６と、二流体ミストノズル３０６に液体を供給するための液体供給経路３０５と、二流体ミストノズル３０６に空気を供給するための空気供給経路３０４と、高圧の液体を生成するための液体ポンプ３０３と、高圧の空気を生成するためのコンプレッサ３０２と、液体ポンプ３０３に液体を供給するための液体タンク３０１とから構成されている噴霧システムの例である。   Further, it is necessary to supply high-pressure air and water to the two-fluid mist nozzle. For this purpose, as shown in FIG. 5, for example, a compressor and a pump are used to supply high-pressure air and water. FIG. 5 shows a two-fluid mist nozzle 306 for spraying mist, a liquid supply path 305 for supplying liquid to the two-fluid mist nozzle 306, and an air supply path 304 for supplying air to the two-fluid mist nozzle 306.

しかしながら、上記の従来技術の場合、外部環境の空気の温度よりも低い温度の水が二流体ミストノズルに供給され、この水が噴霧孔から噴霧されるため、ミストが短時間で蒸発しないという課題がある。この場合、ミストが蒸発する前に路面に落下してしまう傾向にあり、よって、ミストによる気化熱冷却の効果が低くなってしまう。   However, in the case of the above-described conventional technology, water having a temperature lower than the temperature of the air in the external environment is supplied to the two-fluid mist nozzle, and this water is sprayed from the spray holes, so that the mist does not evaporate in a short time. There is. In this case, the mist tends to fall on the road surface before evaporating, and thus the effect of vaporization heat cooling by the mist is reduced.

本発明は、上記課題を解決するものであり、噴出したミストの蒸発時間が短い冷却装置を提供することを目的とする。   The present invention solves the above-described problems, and an object of the present invention is to provide a cooling device with a short evaporation time of ejected mist.

従来の課題を解決するために、本発明の冷却装置は、二流体ミストノズルと、前記二流体ミストノズルに向かう水が流れる水経路と、前記二流体ミストノズルに向かう前記水よりも高温な圧縮空気が流れる空気経路と、前記水経路を流れる水と前記空気経路を流れる高温な圧縮空気との間で熱交換を行う熱交換部と、を備える。   In order to solve the conventional problems, the cooling device of the present invention includes a two-fluid mist nozzle, a water path through which water flows toward the two-fluid mist nozzle, and a compression at a higher temperature than the water toward the two-fluid mist nozzle. An air path through which air flows, and a heat exchange unit that performs heat exchange between water flowing through the water path and high-temperature compressed air flowing through the air path.

本発明の構成によれば、熱交換部において、高温圧縮空気と水との間で熱交換が行われるので、二流体ミストノズルから噴出するミストの温度が上昇する。よって、噴出するミストの蒸発時間が短くなる。   According to the configuration of the present invention, since heat exchange is performed between the high-temperature compressed air and water in the heat exchange unit, the temperature of the mist ejected from the two-fluid mist nozzle rises. Therefore, the evaporation time of the ejected mist is shortened.

本発明によれば、ミストの蒸発時間が短くなり、路面に落下する前に完全に蒸発させることができる。よって、温度低下量を大きくすることができる。また、冷却効果をすばやく得ることができる。   According to the present invention, the evaporation time of mist is shortened and can be completely evaporated before falling on the road surface. Therefore, the amount of temperature decrease can be increased. Moreover, the cooling effect can be obtained quickly.

第１の発明は、冷却装置が、二流体ミストノズルと、前記二流体ミストノズルに向かう水が流れる水経路と、前記二流体ミストノズルに向かう前記水よりも高温な圧縮空気が流れる空気経路と、前記水経路を流れる水と前記空気経路を流れる前記水よりも高温な圧縮空気との間で熱交換を行う熱交換部とを備えることにある。   In the first invention, the cooling device includes a two-fluid mist nozzle, a water path through which water flows toward the two-fluid mist nozzle, and an air path through which compressed air having a temperature higher than that of the water toward the two-fluid mist nozzle flows. And a heat exchanging unit that exchanges heat between water flowing through the water path and compressed air having a temperature higher than that of the water flowing through the air path.

これにより、熱交換部において、水よりも高温な圧縮空気とその水との間で熱交換が行われるので、二流体ミストノズルから噴出するミストの温度が上昇する。よって、噴出するミストの蒸発時間が短くなる。   Thereby, in a heat exchange part, since heat exchange is performed between the compressed air higher than water and the water, the temperature of the mist ejected from a two-fluid mist nozzle rises. Therefore, the evaporation time of the ejected mist is shortened.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明は限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

［構成］
図１は、実施の形態１に係る冷却装置の構成例を示す。 [Constitution]
FIG. 1 shows a configuration example of a cooling device according to the first embodiment.

冷却装置は、二流体ミストノズル６と、水経路８と、空気経路７と、熱交換部２と、コンプレッサ１と、ポンプ３と、第１のバルブ４と、第２のバルブ５、凝縮水回収部９とを備える。   The cooling device includes a two-fluid mist nozzle 6, a water path 8, an air path 7, a heat exchange unit 2, a compressor 1, a pump 3, a first valve 4, a second valve 5, and condensed water. And a collection unit 9.

ポンプ３は、水経路８の上流に設けられており、水経路８に高圧の水を供給する。なお、ポンプ３は、高圧の水を供給するための一例であり、他の方法によって高圧の水が供給されてもよい。水経路８は、最終的に、二流体ミストノズル６に接続されている。   The pump 3 is provided upstream of the water path 8 and supplies high-pressure water to the water path 8. The pump 3 is an example for supplying high-pressure water, and high-pressure water may be supplied by other methods. The water path 8 is finally connected to the two-fluid mist nozzle 6.

コンプレッサ１は、空気経路７の上流に設けられており、空気経路７に、上記の水経路８を流れる水よりも高温な圧縮された空気（以下「高温圧縮空気」という）を供給する。なお、コンプレッサ１は、高温圧縮空気を供給するための一例であり、他の方法によって高温圧縮空気が供給されてもよい。空気経路７は、最終的に、二流体ミストノズル６に接続されている。   The compressor 1 is provided upstream of the air path 7 and supplies the air path 7 with compressed air (hereinafter referred to as “hot compressed air”) that is hotter than the water flowing through the water path 8. The compressor 1 is an example for supplying high-temperature compressed air, and the high-temperature compressed air may be supplied by other methods. The air path 7 is finally connected to the two-fluid mist nozzle 6.

水経路８と空気経路７は、二流体ミストノズル６に到達する途中に、熱交換部２を通るように構成されている。熱交換部２は、水経路８を流れる水と空気経路７を流れる高温圧縮空気との間で熱交換を行うための機構である。   The water path 8 and the air path 7 are configured to pass through the heat exchange unit 2 in the middle of reaching the two-fluid mist nozzle 6. The heat exchanging unit 2 is a mechanism for exchanging heat between water flowing through the water path 8 and high-temperature compressed air flowing through the air path 7.

熱交換部２は、例えば、水経路８の管が空気経路７の管を覆うような二重管構造である。この場合、空気経路７の管を通る高温圧縮空気は、当該管を介して、水経路８の管を通る水と熱交換を行う。そこで、空気経路７の管の素材を、銅やアルミのような、熱伝導率が高いものとしてよい。これにより、効率的な熱交換を行うことができる。また、熱交換部２内において、空気経路７の管の外周面を、フィン等の伝熱面積を増やす構成としてもよい。これにより、さらに効率的な熱交換を行うことができる。   The heat exchanging unit 2 has, for example, a double pipe structure in which the pipe of the water path 8 covers the pipe of the air path 7. In this case, the hot compressed air passing through the pipe of the air path 7 exchanges heat with the water passing through the pipe of the water path 8 through the pipe. Therefore, the material of the tube of the air path 7 may be a material having high thermal conductivity such as copper or aluminum. Thereby, efficient heat exchange can be performed. Moreover, it is good also as a structure which increases the heat transfer area, such as a fin, in the outer peripheral surface of the pipe | tube of the air path 7 in the heat exchange part 2. FIG. Thereby, more efficient heat exchange can be performed.

また、熱交換部２がコンプレッサ１の圧縮機構を冷却できる構成としてもよい。これにより、体積効率が改善され、コンプレッサ１の吐出し流量を増加させることができ、消費電力を低減させることができる。   Further, the heat exchanging unit 2 may be configured to cool the compression mechanism of the compressor 1. Thereby, volumetric efficiency is improved, the discharge flow rate of the compressor 1 can be increased, and power consumption can be reduced.

第１のバルブ４は、空気経路７上の、熱交換部２と二流体ミストノズル６との間に設けられている。第１のバルブ４を調整することにより、空気経路７を流れる空気量を調整することができる。   The first valve 4 is provided between the heat exchange unit 2 and the two-fluid mist nozzle 6 on the air path 7. By adjusting the first valve 4, the amount of air flowing through the air path 7 can be adjusted.

第２のバルブ５は、水経路８上の、熱交換部２とポンプ３との間に設けられている。第２のバルブ５を調整することにより、水経路８を流れる水量を調整することができる。   The second valve 5 is provided between the heat exchange unit 2 and the pump 3 on the water path 8. By adjusting the second valve 5, the amount of water flowing through the water path 8 can be adjusted.

第１及び第２のバルブ４、５を調整することにより、各経路において比較的高密度で流体を流すことができ、よって、流速を低下させて管路圧損を低減させることができる。なお、第１及び第２のバルブ４、５は、設けられなくてもよい。   By adjusting the first and second valves 4 and 5, fluid can be flowed at a relatively high density in each path, so that the flow velocity can be reduced and the pipe pressure loss can be reduced. Note that the first and second valves 4 and 5 may not be provided.

凝縮水回収部９は、空気経路７上の、熱交換部と二流体ミストとの間に設けられている。凝縮水回収部９は、熱交換部２で冷却され空気が凝縮水を発生させた場合に、それを回収し、二流体ミストノズル６への凝縮水の浸入を防ぐ。凝縮水回収部９は、例えば、圧力タンクやサイクロンセパレータ等である。なお、凝縮水回収部９は設けられなくてもよい。   The condensed water recovery unit 9 is provided on the air path 7 between the heat exchange unit and the two-fluid mist. When the condensed water recovery unit 9 is cooled by the heat exchange unit 2 and the air generates condensed water, the condensed water recovery unit 9 recovers the condensed water and prevents the condensed fluid from entering the two-fluid mist nozzle 6. The condensed water collection | recovery part 9 is a pressure tank, a cyclone separator, etc., for example. In addition, the condensed water collection | recovery part 9 does not need to be provided.

［動作］
次に、以上のように構成された冷却装置の動作及び作用を、図１及び図２を参照しながら説明する。 [Operation]
Next, the operation and action of the cooling device configured as described above will be described with reference to FIGS. 1 and 2.

コンプレッサ１は、空気を昇圧して、空気経路７に高温圧縮空気を供給する。ポンプ３は、水経路８に高圧の水を供給する。   The compressor 1 pressurizes air and supplies high-temperature compressed air to the air path 7. The pump 3 supplies high-pressure water to the water path 8.

熱交換部２において、空気経路７を流れる高温圧縮空気と水経路８を流れる水とが熱交換を行う。これにより、高温圧縮空気の温度は低くなり、水の温度は高くなる。このように熱交換が行われた空気と水は、二流体ミストノズル６に供給される。   In the heat exchange unit 2, the high-temperature compressed air flowing through the air path 7 and the water flowing through the water path 8 exchange heat. Thereby, the temperature of hot compressed air becomes low and the temperature of water becomes high. The air and water subjected to heat exchange in this way are supplied to the two-fluid mist nozzle 6.

二流体ミストノズル６が、図３のような内部混合式である場合、内部の気液混合部１０３において、供給された水を、供給された圧縮空気の噴流によって粉砕して微細化する。そして、微細化した水を、圧縮空気と共に噴霧孔１０４から噴霧する。   When the two-fluid mist nozzle 6 is an internal mixing type as shown in FIG. 3, the supplied water is pulverized and refined by the jet of the supplied compressed air in the gas-liquid mixing unit 103 inside. Then, the refined water is sprayed from the spray hole 104 together with the compressed air.

ここで、気液混合部１０３内でも、水と圧縮空気との間で熱交換が行われる。しかし、水と圧縮空気とは混合して噴霧孔ｌ０４まで流れるため、水と圧縮空気との間の相対速度差は小さい。よって、このときの熱伝達率は小さい。さらに、気液混合部１０３内で水と圧縮空気が混合してから噴霧孔１０４に到達するまでの距離は極めて短いため、水と圧縮空気とが熱交換を行う時間も極めて短い。したがって、二流体ミストノズル６内で行われる水と圧縮空気との間の熱交換は、ほとんど影響を及ぼさない。   Here, also in the gas-liquid mixing part 103, heat exchange is performed between water and compressed air. However, since water and compressed air are mixed and flow to the spray hole 104, the relative speed difference between water and compressed air is small. Therefore, the heat transfer coefficient at this time is small. Furthermore, since the distance from mixing of water and compressed air in the gas-liquid mixing unit 103 to reaching the spray hole 104 is extremely short, the time for heat exchange between water and compressed air is also extremely short. Therefore, the heat exchange between the water and the compressed air performed in the two-fluid mist nozzle 6 has little influence.

また、二流体ミストノズル６が、図４のような外部混合式である場合、水と圧縮空気とを別々の経路で噴出するため、水と空気との間で熱交換がほとんど行われない。すなわち、本実施の形態に係る二流体ミストノズル６が内部混合式又は外部混合式の何れであっても、二流体ミストノズル６の内部における水と圧縮空気との間の熱交換は、熱交換部２における熱交換に対してほとんど影響を及ぼさない。   Further, when the two-fluid mist nozzle 6 is an external mixing type as shown in FIG. 4, since water and compressed air are ejected through separate paths, heat exchange is hardly performed between water and air. That is, regardless of whether the two-fluid mist nozzle 6 according to the present embodiment is an internal mixing type or an external mixing type, the heat exchange between water and compressed air inside the two-fluid mist nozzle 6 is a heat exchange. It has little influence on the heat exchange in part 2.

次に、図２の湿り空気線図の例を参照しながら、本実施の形態に係る冷却装置の動作をさらに説明する。   Next, the operation of the cooling device according to the present embodiment will be further described with reference to the example of the wet air diagram of FIG.

図２において、点２５は、二流体ミストノズル６から噴出された空気が混合される前の外部空気（以下「混合前空気」という）の状態を示す。   In FIG. 2, a point 25 indicates a state of external air (hereinafter referred to as “pre-mixing air”) before the air ejected from the two-fluid mist nozzle 6 is mixed.

点２３は、混合前空気に、従来技術に係る二流体ミストノズル６から噴出された空気が混合された後の空気の状態を示す。   Point 23 shows the state of the air after the air ejected from the two-fluid mist nozzle 6 according to the prior art is mixed with the air before mixing.

点２１は、混合前空気に、本実施の形態に係る二流体ミストノズル６から噴出された空気が混合された後の空気の状態を示す。   The point 21 shows the state of the air after the air jetted from the two-fluid mist nozzle 6 according to the present embodiment is mixed with the pre-mixing air.

本実施の形態に係る点２１は、従来技術に係る点２３よりも、乾球温度が低くなっている。なぜなら、本実施の形態では、二流体ミストノズル６から噴出される圧縮空気の熱量が、熱交換部２において水に奪われているからである。   The point 21 according to this embodiment has a lower dry bulb temperature than the point 23 according to the prior art. This is because in the present embodiment, the heat quantity of the compressed air ejected from the two-fluid mist nozzle 6 is taken away by water in the heat exchange unit 2.

点２１及び点２３が示す混合空気にミストが噴出されて当該ミストが蒸発すると、点２１及び点２３の状態は、それぞれ、エンタルピー線２６及び２７上を飽和水蒸気線Ｈに近づく方向に変化し、最終的に、エンタルピー線２６、２７と飽和水蒸気線Ｈとの交点の状態２２、２４となる。   When mist is ejected to the mixed air indicated by the points 21 and 23 and the mist evaporates, the states of the points 21 and 23 change in a direction approaching the saturated water vapor line H on the enthalpy lines 26 and 27, respectively. Eventually, the states 22 and 24 of the intersections between the enthalpy lines 26 and 27 and the saturated water vapor line H are obtained.

図２に示すように、本実施の形態に係るミスト蒸発後の混合空気の状態２２における乾球温度Ｔは、従来技術に係るミスト蒸発後の混合空気の状態２４における乾球温度Ｔ’よりも低くなる。このように、本実施の形態によれば、混合前空気の温度を基準とした場合の、ミストの気化熱冷却による冷却量を増加させることができる。   As shown in FIG. 2, the dry bulb temperature T in the mixed air state 22 after mist evaporation according to the present embodiment is higher than the dry bulb temperature T ′ in the mixed air state 24 after mist evaporation according to the prior art. Lower. Thus, according to the present embodiment, it is possible to increase the amount of cooling by evaporative cooling of the mist when the temperature of the pre-mixing air is used as a reference.

また、ノズルから噴出されたミストは、熱交換部２において高温圧縮空気から熱を受け取って混合前空気よりも高い温度となっているため、蒸発しやすい状態となっている。   Moreover, since the mist ejected from the nozzle receives heat from the high-temperature compressed air in the heat exchanging unit 2 and has a higher temperature than the pre-mixing air, it is in a state of being easily evaporated.

したがって、二流体ミストノズル６から噴出されたミストが蒸発するまでの時間が短くなり、ミストが路面に落下し終える前に蒸発するようになり、冷却効果が増大する。   Therefore, the time until the mist ejected from the two-fluid mist nozzle 6 evaporates is shortened, evaporates before the mist finishes falling on the road surface, and the cooling effect increases.

例えば、夏場において、混合前空気の乾球温度が３５度、ポンプ３が供給する水の温度が２５度の場合、次のように動作する。   For example, in summer, when the dry bulb temperature of the pre-mixing air is 35 degrees and the temperature of the water supplied by the pump 3 is 25 degrees, the operation is as follows.

ポンプ３から供給される水は２５度であるが、熱交換部において高温圧縮空気から熱量を奪い、混合前空気の乾球温度３５度よりも高い水温となる。すなわち、二流体ミストノズル６には、３５度よりも高い温度の水が供給される。したがって、二流体ミストノズル６から噴出されるミストは、短時間で蒸発する。よって、ミストが蒸発せずに路面に落下する傾向にある従来技術と比較して、本実施の形態では、ミストの気化熱冷却による温度低下量が増加する。   Although the water supplied from the pump 3 is 25 degrees, the heat exchange part takes heat from the high-temperature compressed air, resulting in a water temperature higher than the dry bulb temperature of the pre-mixing air of 35 degrees. That is, water having a temperature higher than 35 degrees is supplied to the two-fluid mist nozzle 6. Therefore, the mist ejected from the two-fluid mist nozzle 6 evaporates in a short time. Therefore, compared with the prior art in which mist tends to fall on the road surface without evaporating, in this embodiment, the amount of temperature decrease due to vaporization heat cooling of the mist increases.

コンプレッサ１から供給される高温圧縮空気は１００度を越えているが、熱交換部２において水に熱量を奪われて４０度以下となる。すなわち、二流体ミストノズル６には、４０度以下の圧縮空気が供給される。したがって、二流体ミストノズル６から噴出される圧縮空気は、混合前空気の乾球温度をほとんど上昇させない。よって、高温な圧縮空気を噴出する従来技術と比較して、本実施の形態における温度低下量はさらに増加する。   Although the high temperature compressed air supplied from the compressor 1 exceeds 100 degrees, the amount of heat is deprived by the water in the heat exchanging section 2 and becomes 40 degrees or less. In other words, the two-fluid mist nozzle 6 is supplied with compressed air of 40 degrees or less. Therefore, the compressed air ejected from the two-fluid mist nozzle 6 hardly raises the dry bulb temperature of the air before mixing. Therefore, compared with the prior art which ejects hot compressed air, the amount of temperature drop in the present embodiment further increases.

以上、本発明の実施の形態について説明したが、本発明は上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能である。   Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
