以下、例えば店舗に設置される低温ショーケースや店舗内の空調をするための空気調和装置などの空気調和装置の室外機に散水して冷却する散水冷却装置に係る本発明を実施するための最良の形態について、図１乃至図３を参照しながら説明する。   BEST MODE FOR CARRYING OUT THE INVENTION Best Mode for Carrying Out the Invention According to the Sprinkling Cooling Device that Sprinkles and Cools an Outdoor Unit of an Air Conditioning Device such as a Low Temperature Showcase Installed in a Store or an Air Conditioning Device for Air Conditioning in a Store Will be described with reference to FIGS. 1 to 3.

先ず、１は建物に設置される雨樋２からの雨水が集められて連通管３を介して貯水すると共に水道管４、ボールバルブＶＬ１を介して水道水が供給可能な第１貯水タンク、５はこの第１貯水タンク１と互いに底部ではない下部において連通する連通管６を介して第１貯水タンク１から雨水等が供給される第２貯水タンクである。   First, 1 is a first water storage tank in which rainwater from a gutter 2 installed in a building is collected and stored through a communication pipe 3 and tap water can be supplied through a water pipe 4 and a ball valve VL1, 5 Is a second water storage tank to which rainwater or the like is supplied from the first water storage tank 1 via a communication pipe 6 that communicates with the first water storage tank 1 at a lower portion that is not the bottom.

１０は水浄化装置で、第１貯水タンク１と第２貯水タンク５とを連通する連通管１１から取出し管１２、ボールバルブＶＬ２を介して取出した雨水等を浄化し、この浄化した水を戻り管１３、ボールバルブＶＬ３及び連通管１４を介して第１貯水タンク１及び第２貯水タンク５に戻せるように、水浄化装置１０は第１貯水タンク１及び第２貯水タンク５に対して並列接続され、循環経路が形成される。この水浄化装置１０は、水流路中にフィルター１６、循環ポンプ１７、インジェクター（マイクロバブル発生器など）１８が順に配設され、循環ポンプ１７の駆動により、インジェクター１８と共にオゾン発生装置を構成するオゾン発生器１９において発生されたオゾン（気体）がインジェクター１８を介して循環経路に導入されることとなる。   Reference numeral 10 denotes a water purification device, which purifies rainwater taken out from the communication pipe 11 communicating the first water storage tank 1 and the second water storage tank 5 through the extraction pipe 12 and the ball valve VL2, and returns the purified water. The water purification device 10 is connected in parallel to the first water storage tank 1 and the second water storage tank 5 so as to be returned to the first water storage tank 1 and the second water storage tank 5 through the pipe 13, the ball valve VL 3 and the communication pipe 14. And a circulation path is formed. In this water purification device 10, a filter 16, a circulation pump 17, and an injector (such as a microbubble generator) 18 are arranged in this order in the water flow path, and the ozone constituting the ozone generator together with the injector 18 by driving the circulation pump 17. Ozone (gas) generated in the generator 19 is introduced into the circulation path via the injector 18.

なお、フィルター１６は粒状活性炭、イオン交換樹脂からなり、吸着と濾過機能を有しており、雨水には空気中の硫黄酸化物（ＳＯＸ）や窒素酸化物（ＮＯＸ）などの種々の酸化物等、塩化物（ＮａＣｌ、ＣａＣｌ２、ＭｇＣｌ２）、ミネラル（Ｃａ、Ｍｇ）等が溶解しているが、このフィルター１６がこれらを除去し、また循環経路に導入されたオゾンは第１及び第２貯水タンク１及び５内の雨水等の中のレジオネラ菌等を死滅（除菌）させて、繁殖しないように抑制する。 The filter 16 is made of granular activated carbon and ion exchange resin, and has an adsorption and filtration function. For rainwater, various oxides such as sulfur oxide (SOX) and nitrogen oxide (NOX) in the air, etc. , Chlorides (NaCl, CaCl 2 , MgCl 2 ), minerals (Ca, Mg), etc. are dissolved, but this filter 16 removes them, and the ozone introduced into the circulation path is the first and second ozone. The Legionella bacteria etc. in the rainwater etc. in the water storage tanks 1 and 5 are killed (sanitized) and are prevented from breeding.

そして、循環ポンプ１７の駆動により、オゾン発生器１９で発生させたオゾンをインジェクター１８を介して循環経路に導入しながら、雨水を第１貯水タンク１と第２貯水タンク５との間を浄化しつつ、循環させることを、図示しないタイマーを使用して少なくとも１日に１回行うように、例えばマイクロコンピュータ等で構成された制御装置（図示せず）が制御する。この場合、深夜電力契約時間帯に、この浄化及び循環行なうことにより、より安価に循環動作を実行することができる。   Then, by driving the circulation pump 17, rainwater is purified between the first water storage tank 1 and the second water storage tank 5 while introducing ozone generated by the ozone generator 19 into the circulation path via the injector 18. On the other hand, a control device (not shown) constituted by, for example, a microcomputer is controlled so that the circulation is performed at least once a day using a timer (not shown). In this case, the circulation operation can be executed at a lower cost by performing the purification and circulation in the midnight power contract time zone.

また、第１貯水タンク１には、水位により上下する上下２つのフロート７Ａ、７Ｂを配設し、連通管１１が取付けられる取出し口より上位の所定の第１水位Ｌ１となると下のフロート７Ｂにより第２検出スイッチ８Ｂが作動して、ボールバルブＶＬ１を開いて、水道管４を介して水道水を第１貯水タンク１内に供給させるように制御装置が制御すると共に、この水道水の供給により水位が上昇して第１水位Ｌ１より高い所定の第２水位Ｌ２となると下のフロート７Ｂにより第２検出スイッチ８Ｂが作動して、ボールバルブＶＬ１を閉じて、水道管４を介する水道水の第１貯水タンク１内への供給を停止させるように制御装置が制御する。   Also, the first water storage tank 1 is provided with two upper and lower floats 7A and 7B that rise and fall depending on the water level. When the first water level L1 is higher than the take-out port to which the communication pipe 11 is attached, the lower float 7B When the second detection switch 8B is activated, the ball valve VL1 is opened, and the control device controls the tap water to be supplied into the first water storage tank 1 through the water pipe 4. When the water level rises to a predetermined second water level L2 higher than the first water level L1, the second detection switch 8B is actuated by the lower float 7B, the ball valve VL1 is closed, and the first tap water passing through the water pipe 4 is turned on. The control device controls the supply to the one water storage tank 1 to stop.

従って、第１貯水タンク１及び第２貯水タンク５の貯水量は、常時第１水位Ｌ１より高いレベルに維持され、次回降雨時の際に、できるだけ多くの雨水を貯めるために備えつつ、最低量の貯水量（第１水位Ｌ１以上）を確保している。この最低量の貯水量（第１水位Ｌ１以上）は、第１貯水タンク１内の底部に溜まった塵埃などを第２貯水タンク５との間で循環させない水位の貯水量である。   Therefore, the amount of water stored in the first water storage tank 1 and the second water storage tank 5 is always maintained at a level higher than the first water level L1, and the minimum amount is provided while storing as much rainwater as possible in the next rain. Of water storage (1st water level L1 or more) is secured. This minimum amount of water stored (first water level L1 or higher) is the amount of water stored at a water level that does not circulate dust or the like accumulated at the bottom of the first water storage tank 1 between the second water storage tank 5.

また、雨が降って、雨樋２からの雨水が集められて連通管３を介して貯水して、第３水位Ｌ３に達すると、上のフロート７Ａにより第１検出スイッチ８Ａが作動するので、制御装置は循環ポンプ１７を駆動させ、オゾン発生器１９で発生させたオゾンをインジェクター１８を介して循環経路に導入しながら、雨水を第１貯水タンク１と第２貯水タンク５との間で浄化しつつ、前述したように少なくとも１日に１回循環させることに加え、更にもう１回循環させるように制御装置が制御する。   In addition, when it rains and rainwater from the gutter 2 is collected and stored through the communication pipe 3 and reaches the third water level L3, the first detection switch 8A is activated by the upper float 7A. The control device drives the circulation pump 17 to purify rainwater between the first water storage tank 1 and the second water storage tank 5 while introducing ozone generated by the ozone generator 19 into the circulation path via the injector 18. However, in addition to the circulation at least once a day as described above, the control device controls the circulation so that it is further circulated once more.

そして、インジェクター１８を介して循環経路にオゾンを導入した箇所で、レジオネラ菌等は死滅されるので、この場合の雨水の循環・浄化や前述した１日に１回の循環・浄化は、第１貯水タンク１及び第２貯水タンク５の標準貯水量が各２ｔの計４ｔと想定して、１分間当りの循環量が１０Ｌ（リットル）であるので、例えば４００分間行なわれるように、タイマー（図示せず）の計時に基づいて制御装置が制御する。言い換えると、第１貯水タンク１及び第２貯水タンク５内の雨水等が全て浄化されるように、制御される。   Since ozone is introduced into the circulation path via the injector 18, Legionella bacteria and the like are killed. In this case, the circulation / purification of rainwater and the circulation / purification once a day described above are the first. Assuming that the standard water storage amount of the water storage tank 1 and the second water storage tank 5 is 4 t in total, 2 t, the circulation amount per minute is 10 L (liter), so that a timer (see FIG. The control device controls based on the time (not shown). In other words, the control is performed so that all rainwater and the like in the first water storage tank 1 and the second water storage tank 5 are purified.

なお、前述したように、オゾン発生器１９で発生させたオゾンをインジェクター１８を介して循環経路に導入しながら、雨水を第１貯水タンク１と第２貯水タンク５との間を浄化しつつ循環させるのを、極力回数を減らして行なうのは、第１貯水タンク１及び第２貯水タンク５内のオゾン濃度が高くなるのを防止するためであり、また必要最低限の電力で行なうためで、雨水等を循環経路内に循環させながら少しずつ雨水等の中にオゾンを注入するためである。   As described above, the ozone generated by the ozone generator 19 is introduced into the circulation path via the injector 18 and the rainwater is circulated while purifying between the first water storage tank 1 and the second water storage tank 5. The reason for reducing the number of times as much as possible is to prevent the ozone concentration in the first water storage tank 1 and the second water storage tank 5 from becoming high, and to perform with the minimum necessary power. This is because ozone is injected into the rainwater and the like little by little while circulating the rainwater and the like in the circulation path.

この場合、熱交換器２５にオゾン濃度が高くなった雨水等を散水すると、錆が発生し易くなるので、このオゾン濃度は０．１ｐｐｍ（ｐａｒｔｓ ｐｅｒ ｍｉｌｌｉｏｎ）以下となるのが望ましい。従って、オゾン濃度測定手段（図示せず）により測定された測定値が０．１ｐｐｍを越えた場合には、オゾン発生器１９で発生させたオゾンをインジェクター１８を介して循環経路に導入する動作をその動作中に停止させたり、その動作を行わないように制御装置が制御する。このとき、雨水等の循環はさせるが、オゾンの循環経路への導入をしないように制御してもよいし、雨水等の循環及びオゾンの循環経路への導入の両者を行なわないように制御してもよい。   In this case, if rainwater or the like having a high ozone concentration is sprinkled on the heat exchanger 25, rust is likely to be generated. Therefore, the ozone concentration is desirably 0.1 ppm (parts per million) or less. Therefore, when the measured value measured by the ozone concentration measuring means (not shown) exceeds 0.1 ppm, the operation of introducing the ozone generated by the ozone generator 19 into the circulation path via the injector 18 is performed. The control device controls to stop during the operation or not to perform the operation. At this time, although rainwater is circulated, it may be controlled not to introduce ozone into the circulation path, or it may be controlled not to both circulate rainwater or the like and introduce ozone into the circulation path. May be.

なお、９Ａ、９Ｂは第１貯水タンク１、第２貯水タンク５の上部、即ち第３水位Ｌ３より高い位置に設けられたオーバーフロー管で、降雨により貯まり過ぎを防止するためである。また、本実施形態では、第１貯水タンク１及び第２貯水タンク５とを別体に構成したが一体化して作製してもよいし、また第１貯水タンク１と第２貯水タンク５との２つの貯水タンクとしたが、貯水タンクを１つとして、この１つの貯水タンク内の雨水等を浄化しつつ、循環させてもよい。更には、３つ以上の貯水タンクを使用してもよいが、複数の貯水タンクの場合には、これらの貯水タンクを直列に接続して、これらの貯水タンクを底部ではない下部において連通させると共に、浄化装置はこれらの貯水タンクに対して並列に接続する。   Reference numerals 9A and 9B are overflow pipes provided above the first water storage tank 1 and the second water storage tank 5, that is, at a position higher than the third water level L3, for preventing excessive storage due to rain. Moreover, in this embodiment, although the 1st water storage tank 1 and the 2nd water storage tank 5 were comprised separately, you may produce integrally, and the 1st water storage tank 1 and the 2nd water storage tank 5 are the same. Although the two water storage tanks are used, the water storage tank may be one, and the rain water in the one water storage tank may be purified and circulated. Further, although three or more water tanks may be used, in the case of a plurality of water tanks, these water tanks are connected in series so that these water tanks communicate with each other in the lower part other than the bottom part. The purification device is connected in parallel to these water storage tanks.

２０は第２貯水タンク５から取出し管２１を介して取出した浄化された水を噴射ノズル２７より空気調和装置の室外機である熱交換器２５に散水する散水装置で、塵埃を除去するフィルター２２、圧送ポンプ２３、開閉弁２４、熱交換器２５上に載置される散水制御用電装箱２８、この電装箱２８及びホース２６を介して開閉弁２４に接続される噴射ノズル２７等から構成される。散水制御用電装箱２８内には、散水制御のためのマイクロコンピュータ等の散水制御装置等が搭載されたプリント基板や水配管等が配設されている。   Reference numeral 20 denotes a watering device for spraying purified water taken out from the second water storage tank 5 through the takeout pipe 21 to the heat exchanger 25 which is an outdoor unit of the air conditioner from the injection nozzle 27, and a filter 22 for removing dust. , A pumping pump 23, an on-off valve 24, a watering control electrical box 28 mounted on the heat exchanger 25, an electrical nozzle 28 connected to the on-off valve 24 via the electrical box 28 and a hose 26, etc. Is done. In the electrical control box 28 for watering control, a printed circuit board, water piping, and the like on which a watering control device such as a microcomputer for watering control is mounted are disposed.

そして、散水制御装置は開閉弁２４の開閉制御を行うが、この開閉弁２４が閉じると圧送ポンプ２３は高圧状態となって、圧送ポンプ２３は自身で運転を停止し、開くと低圧状態となって、自身で運転を開始することとなるものである。従って、散水制御装置が開閉弁２４の開閉制御を行うことにより、結果として圧送ポンプ２３を制御することとなるものである。   The sprinkler control device controls the opening / closing of the opening / closing valve 24. When the opening / closing valve 24 is closed, the pumping pump 23 is in a high pressure state, and the pumping pump 23 stops its operation, and when it is opened, it is in a low pressure state. Then, you will start driving yourself. Therefore, the water spray control device controls the opening / closing of the on-off valve 24, and as a result, controls the pressure-feed pump 23.

そして、空気調和装置の室外機である熱交換器２５に散水装置２０により散水するのを、熱交換器２５の冷媒入口又は冷媒出口の冷媒圧力が所定値以上になったこと、又は熱交換器２５の冷媒入口の冷媒温度が所定温度以上になったこと、又は熱交換器２５（冷媒管やフィン等）の温度が所定温度以上になったこと、又は空気調和装置の圧縮機の電動装置に流れる電流が所定値以上になったことを検出する検出装置を設けて、この検出装置の出力に基づいて、即ち前述したような所定値以上になったこと又は所定温度以上を検出するとタイマー（図示せず）による所定時間だけ開閉弁２４を開くように制御し、前述したように、圧送ポンプ２３を運転させて散水装置２０により熱交換器２５に散水するように制御する。   Then, the water sprinkler 20 sprays the heat exchanger 25 that is an outdoor unit of the air conditioner when the refrigerant pressure at the refrigerant inlet or the refrigerant outlet of the heat exchanger 25 exceeds a predetermined value, or the heat exchanger. The refrigerant temperature at the refrigerant inlet 25 has become equal to or higher than the predetermined temperature, or the temperature of the heat exchanger 25 (refrigerant tubes, fins, etc.) has become equal to or higher than the predetermined temperature, or the electric motor of the compressor of the air conditioner A detection device is provided for detecting that the flowing current has exceeded a predetermined value, and based on the output of the detection device, that is, when a detection has been made that the current has exceeded the predetermined value or a predetermined temperature is detected (see FIG. The on-off valve 24 is controlled to open for a predetermined time by a not-shown), and as described above, the pumping pump 23 is operated to control the sprinkler 20 to spray the heat exchanger 25.

これにより、空気調和装置の冷凍サイクルの成績係数ＣＯＰ（ＣｏｅｆｆｉｃｉｅｎｔＯｆ Ｐｅｒｆｏｒｍａｎｃｅ）の向上や消費電力の減少を図ることができる。   Thereby, the coefficient of performance COP (Coefficient of Performance) of the refrigeration cycle of the air conditioner can be improved and the power consumption can be reduced.

以上のような実施形態によれば、雨水を貯水して、浄化して空気調和装置の室外機に掛けることにより、冷却効果を上げるのに、安価で室外機の腐食も極力抑えて行なうことができる。   According to the embodiment as described above, rainwater is stored, purified, and applied to the outdoor unit of the air conditioner, so that the cooling effect is increased, and the corrosion of the outdoor unit can be performed at a low cost and as much as possible. it can.

また、以上の実施形態では、噴射ノズル２７から空気調和装置における室外機である熱交換器２５に第２貯水タンク５からの浄化された水を散水するようにしたが、この熱交換器２５に限らず、建築物や自動車などに散水したり、庭や樹木などへ散水してもよい。   In the above embodiment, the purified water from the second water storage tank 5 is sprinkled from the injection nozzle 27 to the heat exchanger 25 that is an outdoor unit in the air conditioner. Not limited thereto, water may be sprinkled on buildings, cars, etc., or watered on gardens or trees.

以上本発明の実施態様について説明したが、上述の説明に基づいて当業者にとって種々の代替例、修正又は変形が可能であり、本発明はその趣旨を逸脱しない範囲で前述の種々の代替例、修正又は変形を包含するものである。   Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various alternatives described above without departing from the spirit of the present invention.
