The present invention relates to a compact air conditioner that can be used. Background art
蒸発器で発生した水蒸気を凝縮器で凝縮する手段として冷水を用い、 蒸発器に おける気化熱で冷風を得る冷房装置において、 従来、 別置の冷却塔内でファ ンに よる空気流を生じさせて前記冷水を生成し、 これを前記凝縮器へ管路を介して送 るようにした吸収式あるいは圧縮式の冷房装置が開発されており、 この方式のも のは、 特に夏期酷暑時に使用して単なる空冷式のものよりかなり低温の冷房が可 能であることが知られている。 ただし、 この方式で従来のものは、 冷却塔を含む 設備全体がかなり大型である。  In a cooling device that uses cold water as a means to condense water vapor generated in an evaporator with a condenser and obtains cool air by the heat of vaporization in the evaporator, conventionally, an airflow by a fan is generated in a separate cooling tower. Absorption-type or compression-type cooling devices have been developed in which the above-mentioned cold water is generated and sent to the condenser via a pipeline.This type of cooling device is used especially in extremely hot summer months. It is known that cooling at a considerably lower temperature than that of a simple air-cooled type is possible. However, in this conventional method, the entire equipment including the cooling tower is quite large.
吸収式の冷房装置の作動原理を第 7図によって説明すれば、 内部を低圧とした 蒸発器 6 0と室内の空調機 6 1をループ状の管路 6 2で結んてこの間を水が循環 するようにし、 別系統の水を凝縮器 6 3から前記蒸発器 6 0内に導いて該蒸発器 内で滴下、 気化させる。 これによつて前記空調機 6 1 へ流れる水が冷水化し冷風 の発生源となる。 前記蒸発器 6 0での気化を促進するために該蒸発器 6 0と吸収 器 6 とを吸気管 6 5で結び、 該吸収器 6 内で、 蒸発器 6 0から吸気管 6 5を 介して取り込まれる水蒸気 （符号 7 5で示す） を吸収液 6 6に吸収させて再生器 6 7へ液送する。 この水を含んだ液体 （水十吸収液） 7 6は前記再生器 6 7をパ ーナ 6 8等で加熱することにより、 再び水蒸気 7 7 と吸収液 6 6に分離し、 吸収 液 6 6は他の管 （吸収液管 6 9 ) を通して前記吸収器 6 へ、 水蒸気 7 7は凝縮 器 6 3へ送って別置の冷却塔 7 0からの冷水で凝縮され、 蒸発器 6 0内で前述の ように滴下し、 再度水蒸気 7 5となる。  The operating principle of the absorption-type cooling system will be described with reference to Fig. 7.The evaporator 60, which has a low internal pressure, and the indoor air conditioner 61 are connected by a loop-shaped pipe 62, and water circulates between them. In this way, another system of water is introduced from the condenser 63 into the evaporator 60, and is dropped and vaporized in the evaporator. As a result, the water flowing to the air conditioner 61 becomes cold water and becomes a source of cold air. In order to promote vaporization in the evaporator 60, the evaporator 60 and the absorber 6 are connected by an intake pipe 65, and in the absorber 6, the evaporator 60 is connected via an intake pipe 65. The absorbed water vapor (denoted by reference numeral 75) is absorbed by the absorbing liquid 66 and sent to the regenerator 67. The water-containing liquid (water-absorbing liquid) 76 is again separated into water vapor 77 and absorbing liquid 66 by heating the regenerator 67 with a panner 68 or the like. Is sent to the absorber 6 through another pipe (absorbing liquid pipe 69), and the water vapor 77 is sent to the condenser 63 to be condensed with cold water from a separate cooling tower 70, Then, water vapor becomes 75 again.
上述した従来の冷却塔を有する吸収式冷房装置あるいは圧縮式冷房装置は、 前 述の如く夏期性能はよいが、 室外機全休が大き く、 一般家庭用として簡単に設置 できない欠点がある。 特に従来の冷却塔は本体機器と完全に分離しており、 建物 の屋上等に別置形態で設置される構成が多く、 装置全体としてかなり大形化し、 大重置で設備費も高価となり、 小型の家庭用には不向きであった。 Absorption-type or compression-type cooling devices having the conventional cooling towers described above are As mentioned above, the summer performance is good, but there is a drawback that the outdoor unit is completely closed and cannot be easily installed for general household use. In particular, the conventional cooling tower is completely separated from the main equipment, and is often installed separately on the rooftop of a building, etc. It was unsuitable for small home use.
また、 この種の冷房装置では、 冷却塔は冷水の生成だけを目的とするものであ り、 冷房装置を冬期に暖房用に切り替えて使用する際は全く利用されず、 冷却塔 設備の利用効率が悪いという問題があった。 さらに、 従来の吸収式のものは、 冷 房装置を吸収ヒー 卜ポンプとして作動させて冬期暖房用の機能をもたせることは できなかった。  Also, in this type of cooling device, the cooling tower is only for the purpose of generating cold water, and is not used at all when the cooling device is switched to heating for use in winter, and the efficiency of the use of the cooling tower equipment is reduced. There was a problem that was bad. Furthermore, conventional absorption-type air-conditioning units could not operate the cooling device as an absorption heat pump to provide a function for heating in winter.
そこで本発明は、 前記冷却塔自体を室外機の主要部分とすることで全体の小形 軽量化を図り、 高効率で夏期高温時に家庭用として簡単に設置できる冷却塔式小 型冷房装置を提供することにある。  Accordingly, the present invention provides a cooling tower-type compact air-conditioning apparatus that is compact and lightweight as a whole by using the cooling tower itself as a main part of an outdoor unit, and that is highly efficient and can be easily installed for home use at high temperatures in summer. It is in.
また本発明は、 夏期の冷房用だけでなく簡単な切り替え操作により、 かつ任意 の外部の微温熱源の水を利用して、 吸収ヒー トポンプ方式の作動を可能とする冬 期暖房用としても使用でき、 しかも霜取りや氷結取りの煩雑さがない小型冷暖房 装置を提供することを目的とする。 発明の開示  In addition, the present invention can be used not only for cooling in summer but also for winter heating in which an absorption heat pump system can be operated by a simple switching operation and using water from an arbitrary external low-temperature heat source. It is another object of the present invention to provide a small-sized air conditioner that does not require complicated defrosting or freezing. Disclosure of the invention

また本発明の小型冷房装置は、 冷却水用の冷却塔を装備した圧縮式冷房装置に おいて、 前記冷却塔の内部空間内に、 夏期用コンデンサとなる冷房用熱交換器を 収容し、 それが該冷却塔内部の気流および水流と接触して直接冷却される構成と したものである。  Further, the compact cooling device of the present invention is a compression type cooling device equipped with a cooling tower for cooling water, wherein a cooling heat exchanger serving as a condenser for summer is accommodated in an internal space of the cooling tower. Has a configuration in which it is directly cooled by contact with the air stream and water stream inside the cooling tower.
さらに本発明は、 冬期に前記冷却塔の通常の空気流の流入口および流出ロを密 閉して塔内の空気流を停止し、 塔内部に水だけを循環させて前記コンデンサおよ び前記吸収器から生じる発熱を水にて受け取って該水を温水として冬期暖房給湯 源とするように構成し、 かつ前記エバポレータには他の微温熱源からの微温水を 供給して蒸発熱源とし、 これによつて冬期に暖房可能としたものである。 Further, in the present invention, in the winter season, the inlet and outlet of the normal airflow of the cooling tower are closed to stop the airflow in the tower, and only the water is circulated inside the tower, so that the condenser and And the heat generated by the absorber is received by water, and the water is used as hot water as a source of heating and hot water in winter, and the evaporator is supplied with low-temperature water from another low-temperature heat source to serve as an evaporation heat source. This enables heating in winter.
このようにすることによって、 吸収式および圧縮式冷暖房装置の室外機部分を 、 冷却塔を主体とするものとし、 その冷却塔の内部空間に、 吸収式にあってはコ ンデンサおよび吸収器、 また圧縮式ではそのコンデンサ、 等冷却を必要とする機 器をすベて直接収納し、 前記冷却塔内にて流下する水によってそれらが良く濡れ るとともに、 冷却塔内を流動する空気にも良く接触し、 これによつて各部分の外 面にて直接的な冷却熱伝達を受けるようにし、 また前記冷却塔の外部に近接して , 吸収式においてはボイ ラ、 ポンプ等、 圧縮式においてはコ ンプレッサを近接配 置し、 もって全体として軽量かつコ ンパク 卜な一体型室外機を形成することがで きる。  By doing so, the outdoor unit of the absorption type and compression type air conditioner is mainly composed of a cooling tower, and the internal space of the cooling tower is provided with a capacitor and an absorber in the absorption type.

さらに、 本発明においては、 特に冬期暖房用に資するため、 冷却塔壁を良好な 断熱壁とし、 かつ、 冬期暖房時には空気流を停止するように空気流入口を閉塞す る。  Furthermore, in the present invention, in order to contribute particularly to heating in winter, the cooling tower wall is a good heat insulating wall, and the air inlet is closed so as to stop the air flow during heating in winter.
そして吸収式においては、 そのエバボレータに適当な微温熱源より得られる微 温水を循環させて蒸発せしめ、 また前記冷却塔内にあるコ ンデンサおよび吸収器 では、 その発生する熱を、 該冷却塔内を循環する水流に伝えて該冷却塔内に温水 を生じさせるようにし、 この温水を室内暖房の熱源とする。  In the absorption type, the evaporator circulates and evaporates the slightly heated water obtained from an appropriate slightly heated heat source, and the condenser and the absorber in the cooling tower transfer the generated heat to the inside of the cooling tower. The water is transmitted to the circulating water stream to generate hot water in the cooling tower, and this hot water is used as a heat source for indoor heating.
また圧縮式においては、 従来のようにコ ンプレッサからの作動流体の流れの方 向を逆にして前記冷却塔内に存在する夏期用コンデンサを逆に冬期用蒸発器とす る力 特に本発明においては、 上記のように冷却塔内の空気流を停止しておいて 、 別の適当な微温を有する地下水等の温熱源水を直接冬期用蒸発器の周辺に良く 噴霧して壁を流下させ、 その保有顕熱をもって暖房の熱源とするように作動させ る。  In addition, in the compression type, the force of reversing the direction of the flow of the working fluid from the compressor as in the prior art and making the summer condenser present in the cooling tower a conversely a winter evaporator, especially in the present invention, As described above, the air flow in the cooling tower is stopped as described above, and another heat source water such as groundwater having a suitable low temperature is sprayed directly around the evaporator for winter season to flow down the wall, The sensible heat is used to operate as a heat source for heating.

次に上述の実施例における夏期冷房動作を説明する。 まず、 冷却塔 1 の外気取 入口開閉ダンパ 3 1および頂部放出口開閉ダンバ 3 2が開かれ、 かつフマ ン 8か 駆動され、 同時にポンプ 1 2によりノズル 1 3から上下に水噴霧がなされる。 冷 却塔 1内には上昇空気流 4 4が生じ、 この空気流とノズル 1 3からの水噴霧とに より凝縮器 3および吸収器 4の外周が濡れて冷却され、 これによつて前述のよう に吸収器 4内で吸収液の水蒸気吸収が進み、 したがって蒸発器 2 9では水蒸気の 飽和が抑制され、 エバポレータ 7による噴霧水の水蒸気化が良好に行われ、 蒸発 器 2 9 と室内機 3 5を循環する水は蒸発器 2 9内で冷水となり、 蒸発器 2 9の下 部から送水ポンプ 4 2によって室内機 3 5へ送られ、 冷房目的を達成する。 なお 蒸発器 2 9は低圧状態に保持されている。 Next, the summer cooling operation in the above embodiment will be described. First, the outside air intake opening / closing damper 31 and the top discharge opening / closing damper 32 of the cooling tower 1 are opened, and the fan 8 is driven. At the same time, water is sprayed up and down from the nozzle 13 by the pump 12. The rising air flow 44 is generated in the cooling tower 1, and the outer circumference of the condenser 3 and the absorber 4 is wet and cooled by the air flow and the water spray from the nozzle 13. As described above, the absorption of water vapor by the absorption liquid proceeds in the absorber 4, and therefore, the saturation of the water vapor is suppressed in the evaporator 29, and the vaporization of the spray water by the evaporator 7 is performed well, and the evaporator 29 and the indoor unit 3 The water circulating in 5 becomes cold water in the evaporator 29 and is sent from the lower part of the evaporator 29 to the indoor unit 35 by the water supply pump 42 to achieve the cooling purpose.

第 4図は第 1図の実施例の吸収式冷房装置を冬期暖房用に切り替えた状態の概 略図である。 各四方弁 3 6 , 3 7 , 3 8は第 1図の状態から 9 0 ° 回転され、 ま た塔上下の各開閉ダンバ 3 1； 3 2が閉じられ、 かつ電動ファ ン 8 も停止される 。 四方弁 3 6 , 3 7 , 3 8の同時切り替えにより、 図示のごとく冬期暖房用熱源 水 3 9の熱交換器 4 0は前記弁 3 6 , 3 7を介して蒸発器 2 9と連通し、 室内機 3 5は冷却塔 1内の水 1 1が冷却塔循環水管路 5 6を介して循環することとなる 。 ここで蒸発器 2 9には熱源水 3 9内の熱交換器 4 0を通って温められた温熱水 が出入して蒸発熱を発生し、 この温熱蒸気が吸収器 4にもたらされ、 一方、 冷却 塔 1内に噴霧される水 1 1 は凝縮器 3および吸収器 を濡らしてその熱を奪い温 熱水となって前記管路 5 6から室内機 3 5に送られ、 結局温風が室内機 3 5から 室内へ送出されて暖房目的を達する。 この場合、 前記管路 5 6と連通する室内機 3 5の冷水管 5 4は温水管となることは勿論である。 なお、 このときは再生機 5 、 凝縮器 3および吸収器 4などの温度は従来のヒートポンプと同様にそれぞれ冷 房モード時より約 3 0 ° 〜4 0 ° C上昇する。  FIG. 4 is a schematic diagram showing a state in which the absorption cooling device of the embodiment shown in FIG. 1 is switched to heating for winter. Each four-way valve 36, 37, 38 is rotated 90 ° from the state shown in Fig. 1, the open / close dampers 3 1; 3 2 at the top and bottom of the tower are closed, and the electric fan 8 is also stopped. . By the simultaneous switching of the four-way valves 36, 37, 38, the heat source 40 for winter heating heat water 39 communicates with the evaporator 29 via the valves 36, 37, as shown in the figure. In the indoor unit 35, the water 11 in the cooling tower 1 is circulated through the cooling tower circulation water pipe 56. Here, hot water warmed through the heat exchanger 40 in the heat source water 39 enters and goes out of the evaporator 29 to generate evaporation heat, and this hot steam is brought to the absorber 4. The water 11 sprayed into the cooling tower 1 wets the condenser 3 and the absorber and removes its heat, becomes hot water, is sent from the pipe 56 to the indoor unit 35, and eventually generates hot air.
