冷温水コイルにフィン群を配置して冷温水コイルで冷却又は加温したフィン群によって、フィン群に吹付けた空気を冷却又は加熱することは、エアーコンディショニング分野の慣用技術であり、現在、冷温水コイルを使用した冷暖房手段は実用に供されている。 It is a conventional technique in the field of air conditioning to cool or heat the air blown to the fin group by arranging the fin group in the cold / hot water coil and cooling or heating the fin group with the cold / hot water coil. Cooling and heating means using a water coil are put into practical use.

図１２は、特許文献１で挙げた従来例１の空気熱交換器であり、本出願人が特願２０１１−２４０２３７（特許第５３９６５８０号）として提案し、商品化しているものであって、ステンレス鋼板製のケーシング内の長手方向に冷温水コイルを配置し、吸気側からケーシング内に流入する空気流を冷温水コイルの上面空間に案内し、フィン間の間隙に差し込みする高さの異なる風偏向板群によって順次通過風量を減少させて、上面空間から各フィン間の間隙を貫流させて熱交換作用を行い、下面空間から、夏期は除湿冷却空気、冬期は加熱空気を居室内へ送風する。 FIG. 12 shows the air heat exchanger of Conventional Example 1 mentioned in Patent Document 1, which was proposed and commercialized by the applicant as Japanese Patent Application No. 2011-240237 (Patent No. 5396580), and is made of stainless steel. A cold / hot water coil is arranged in the longitudinal direction in the steel plate casing, and the air flow flowing into the casing from the intake side is guided to the upper surface space of the cold / hot water coil, and the wind deflection with different heights is inserted into the gap between the fins. The passing air volume is sequentially reduced by the plate group, and heat exchange action is performed by passing through the gaps between the fins from the upper surface space, and dehumidifying and cooling air is blown from the lower surface space into the living room in summer and heated air in winter.

従来例１（図１２）の空気熱交換器は、両端に継手部材を配置してダクト管と接続するものであり、ケーシングの外側に粘性断熱材を貼着して結露防止を図り、冷房時に発生する結露水は止水板の吸気側に配置するドレンパイプから排出するものであって、冷温水コイルはエンドプレートの取付片を介してボルトで固定され、狭いスペースにも配置可能な小型で高性能の空気熱交換器である。 In the air heat exchanger of the conventional example 1 (FIG. 12), joint members are arranged at both ends to connect to the duct pipe, and a viscous heat insulating material is attached to the outside of the casing to prevent dew condensation during cooling.

It is a high-performance air heat exchanger.

特開２０１３−９６６４７号公報（特許第５３９６５８０号）Japanese Unexamined Patent Publication No. 2013-96647 (Patent No. 5396580)

従来例１（図１２）のステンレス鋼板製空気熱交換器は、重量が重く、地震時の横揺れによる空気熱交換器の破損や落下の恐れがあり、ケーシングの両端に継手部材を接続するため部材や取付けによるコスト面の課題があり、また鋼板製のケーシングは上側函体をボルト接合し、空気熱交換器自体の結露防止及び放熱防止対策として函体表面に厚さ１３ｍｍの粘性断熱材を貼着するため、製作日数が長くなり組立作業性やコスト面の課題がある。 The stainless steel plate air heat exchanger of Conventional Example 1 (FIG. 12) is heavy and may be damaged or dropped due to rolling during an earthquake. Therefore, joint members are connected to both ends of the casing. There is a cost issue due to the members and mounting, and the upper box is bolted to the steel casing, and a 13 mm thick viscous heat insulating material is applied to the surface of the box as a measure to prevent dew condensation and heat dissipation from the air heat exchanger itself. Since it is attached, it takes a long time to manufacture, and there are problems in terms of assembly workability and cost.

また、従来例１（図１２）の空気熱交換器は、吸気空気に含まれる塵や埃でドレンパイプに目詰りを生じた場合、懐の狭い天井空間から取外して分解し清掃を実施しなければならず、貼着断熱材の切断や復旧、冷温水コイルの取り外し、及び熱媒の処理などメンテナンス作業が煩雑となる。また、薄厚の各偏向板は密接した各フィン間おのおのへの深さ６．２ｍｍのく字形状の屈曲配置であり、空気流の押圧に対する冷温水コイル上面からの突出長さ保持の信頼性の問題がある。 In addition, when the drain pipe is clogged with dust or dirt contained in the intake air, the air heat exchanger of the conventional example 1 (FIG. 12) must be removed from the narrow ceiling space, disassembled, and cleaned. In addition, maintenance work such as cutting and restoration of the attached heat insulating material, removal of the hot and cold water coil, and treatment of the heat medium becomes complicated. In addition, each thin polarizing plate has a dogleg-shaped bending arrangement with a depth of 6.2 mm between each of the close fins, and the reliability of maintaining the protrusion length from the upper surface of the cold / hot water coil against the pressure of the air flow is reliable. There's a problem.

本発明は、従来例のこれらの問題を一挙に解決又は改善して、高効率の冷却加熱空気を供給するとともに、メンテナンス性が容易な空気熱交換器を提供することを目的とする。
本発明はさらに、軽量化を図って耐震性や作業性を向上し安価な空気熱交換器を提供することを目的とする。An object of the present invention is to solve or improve these problems of conventional examples at once, to supply highly efficient cooling and heating air, and to provide an air heat exchanger that is easy to maintain.
Another object of the present invention is to provide an inexpensive air heat exchanger with reduced weight, improved seismic resistance and workability.

本発明の空気熱交換器は、ケーシング（外箱）内の長手方向に冷温水コイルを傾斜配置し、吸気側からケーシング内に流入する空気流は冷温水コイルの上面空間に案内し、ケーシング内に吸気側から給気側に亘って順じ通過風量が減少するように配置した、両側の受板に風偏向板群を固着一体化とした風偏向具によって、複数の風偏向板によって、冷温水コイルの上面空間から冷温水コイルの下面空間へ、空気流を順次偏向案内して冷温水コイルのフィン群の隙間を貫流案内し、給気側からは、冷温水コイルの下面空間からケーシングの幅を傾斜減縮して空気流を流出させるものである。 In the air heat exchanger of the present invention, the cold / hot water coils are inclined in the longitudinal direction in the casing (outer box), and the air flow flowing into the casing from the intake side is guided to the upper surface space of the cold / hot water coils in the casing. By the wind deflector, which is arranged so that the passing air volume decreases from the intake side to the air supply side, and the wind deflection plates are fixed and integrated on the receiving plates on both sides, the temperature is cooled by the multiple wind deflection plates. The air flow is sequentially deflected and guided from the upper surface space of the water coil to the lower surface space of the cold / hot water coil to guide the air flow through the gaps between the fins of the cold / hot water coil, and from the air supply side, from the lower surface space of the cold / hot water coil to the casing. The width is tilted and reduced to allow the air flow to flow out.

この場合、冷温水コイルは、従来の冷温水コイルと同形態に、並列連通の循環パイプの外周にスリットを備えた板状の放熱用フィン群を密集平行形態に配置し、循環パイプに冷水又は温水を循環させるものであるが、熱交換用の空気の流し方向は、冷温水コイルの長手方向、即ち放熱フィン群に直行方向に熱交換用空気を流し、図１２の従来例より２７％増とした放熱フィン群によって空気を冷却又は加熱するものである。 In this case, the cold / hot water coil has the same form as the conventional cold / hot water coil, in which plate-shaped heat dissipation fins having slits on the outer periphery of the circulation pipe of parallel communication are arranged in a dense parallel form, and cold water or cold water or Although hot water is circulated, the heat exchange air flow direction is 27% higher than that of the conventional example of FIG. 12 by flowing heat exchange air in the longitudinal direction of the cold / hot water coil, that is, in the orthogonal direction to the heat radiation fins. The air is cooled or heated by the heat radiation fin group.

また、発泡系や繊維系の保温材のケーシングは、冷温水コイルを傾斜収納するコ字形状の本体と本体上面を閉止する形態の蓋とで形成する方形の上下分離型とし、本体と蓋の接続部はテープ貼着で一体化するものであり、吸気側から給気側に向かって、断面角パイプ形状の幅広部と、上視台形状の傾斜部と、小幅の幅狭部との連続形態で構成される。 In addition, the casing of the foam-based or fiber-based heat insulating material is a square upper and lower separated type formed by a U-shaped main body that tilts and stores the cold / hot water coil and a lid that closes the upper surface of the main body. The connection part is integrated by sticking tape, and from the intake side to the air supply side, a wide part having a square cross-section pipe shape, an inclined part having an upper viewing table shape, and a narrow part having a narrow cross section are continuously connected. Consists of morphology.

幅広部は、吸気側のダクト管を接続するための継手部材、例えばダクトニップルを嵌合する上下前支持台及び冷温水コイルの支承をするための支承部、冷温水コイルの表面から落下する結露水を処理するための排水部とを備え、傾斜部に給気側の継手部材を嵌合する上下先支持台を備え、幅狭部は傾斜部から連続する上下支持台を備えており、ケーシングの形状寸法は冷温水コイルの寸法によって適宜決定するものである。 The wide part is a joint member for connecting the duct pipe on the intake side, for example, an upper and lower front support base for fitting the duct nipple, a bearing part for supporting the hot / cold water coil, and dew condensation falling from the surface of the hot / cold water coil. It is equipped with a drainage section for treating water, a vertical tip support base for fitting an air supply side joint member to the inclined portion, and a vertical support base continuous from the inclined portion in the narrow portion, and a casing. The shape and dimensions of the above are appropriately determined by the dimensions of the hot and cold water coil.

ケーシングは、ポリスチレンフォーム、ウレタンフォーム、ポリエチレンフォームなどの発泡プラスチック系や、グラスウールなどの繊維系の保温材であればよく、典型的には、低熱伝導性で、圧縮強度に優れる密度３３ｋｇ／ｍ３の、射出成型が可能なビーズ法ポリスチレンフォームが最適であり、例えば、放熱フィンの左右方向長さ（幅）が２０３ｍｍ、上下方向長さ（高さ）が４４ｍｍ、フィン群の長さが６５０ｍｍの冷温水コイルを内蔵するケーシングは、幅広部の幅が２６７ｍｍ、高さが１９９ｍｍ、長さが９９０ｍｍ、幅広部に連続する傾斜部の給気側は幅が２１１ｍｍ、高さが１９９ｍｍ、長さが５０ｍｍであり、傾斜部から小幅の延出形態の幅狭部の長さが５０ｍｍであって、総幅は２６８ｍｍ、総高さが１９９ｍｍ、総長さが１０９０ｍｍの軽量（ケーシング重量：１．３ｋｇ）で断熱性、耐食性に優れ、製作日数を短縮した空気熱交換器を提供することができる。The casing may be a foamed plastic-based heat insulating material such as polystyrene foam, urethane foam, or polyethylene foam, or a fiber-based heat insulating material such as glass wool, and typically has a density of 33 kg / m 3 having low thermal conductivity and excellent compressive strength. The beaded polystyrene foam that can be injection-molded is optimal. For example, the heat radiation fins have a lateral length (width) of 203 mm, a vertical length (height) of 44 mm, and a fin group length of 650 mm. The casing with a built-in cold / hot water coil has a wide portion with a width of 267 mm, a height of 199 mm, and a length of 990 mm, and the air supply side of the inclined portion continuous with the wide portion has a width of 211 mm, a height of 199 mm, and a length. It is 50 mm, the length of the narrow portion extending from the inclined portion to the narrow width is 50 mm, the total width is 268 mm, the total height is 199 mm, and the total length is 1090 mm, which is lightweight (casing weight: 1.3 kg). It is possible to provide an air heat exchanger having excellent heat insulation and corrosion resistance and shortening the production time.

排水部は、冷温水コイル後方の本体底板に設置し、夏期の冷房時において冷温水コイルの表面を露点以下の温度とし、吸気側から流入する空気を冷却させて冷温水コイルに発生する結露水を排出するものであり、対面する本体の側板間の幅寸法全長に亘り、底板上面から導水溝に向う結露水を誘導する面幅２８ｍｍの斜辺を設け、隣接して幅２０ｍｍの導水溝を配置し、導水溝に隣接して底板上から高さ４２ｍｍ、幅が４４ｍｍの断面台形状の防水堤を配置して給気側への流水を阻止する。 The drainage section is installed on the bottom plate of the main body behind the cold / hot water coil, and the surface of the cold / hot water coil is kept at a temperature below the dew point during cooling in summer, and the air flowing in from the intake side is cooled to generate condensed water in the cold / hot water coil. A slope with a surface width of 28 mm is provided to guide dew condensation water from the top surface of the bottom plate toward the water guide groove over the entire width dimension between the side plates of the main body facing each other, and a water guide groove with a width of 20 mm is arranged adjacent to the water guide. Then, a trapezoidal waterproof bank having a height of 42 mm and a width of 44 mm is arranged adjacent to the headrace groove to prevent water from flowing to the air supply side.

また、導水溝の中央に排水孔を穿孔し、底板下面の排水孔近傍に台形状の水切溝を円形状に穿設することで、結露水は底板下面を伝わることなく落下させることができる。また、本体の前支持台から防水堤までの底板上面及び両側の側板下方に酢酸ビニル系の防水剤を塗布して防水層を形成し、結露水の浸透を阻止して空気熱交換器の耐久性を維持するのが好ましい。 Further, by drilling a drainage hole in the center of the headrace groove and drilling a trapezoidal drainage groove in the vicinity of the drainage hole on the lower surface of the bottom plate in a circular shape, the condensed water can be dropped without being transmitted to the lower surface of the bottom plate. In addition, a vinyl acetate-based waterproofing agent is applied to the upper surface of the bottom plate from the front support of the main body to the waterproof bank and below the side plates on both sides to form a waterproof layer, which prevents the infiltration of condensed water and makes the air heat exchanger durable. It is preferable to maintain the sex.

ドレンパンは、排水孔から落下する結露水を受け止め排出するものであり、上面が開放された箱形状の、ドレンパンの底板は、ケーシングの幅方向に結露水を誘導する傾斜状とし、高さが異なる側板の水下側にドレン管を左右方向に突出配置して結露水を排出させる、除湿型の空気熱交換器を構築するものである。 The drain pan receives and discharges the condensed water that falls from the drain hole, and the bottom plate of the drain pan, which has a box shape with an open top surface, has an inclined shape that guides the condensed water in the width direction of the casing, and has different heights. A dehumidifying air heat exchanger is constructed by arranging a drain pipe protruding in the left-right direction on the underwater side of the side plate to discharge dew condensation water.

ドレンパンの取付けは、コ字形状の接続金具を用いて実施され、接続金具の板状の上辺をケーシング天板上に、接続金具の両板状側辺をケーシングの両側板におのおの被着形態に当接配置し、両側辺下端から外方に突出したボルト挿入用孔を備えた折曲辺と、ドレンパンの左右方向に対面する側板の上端中央から外方に、予め突出したボルト挿入用孔を備えた突出片とを整合し、両挿入用孔を介して長寸のボルト及びナットを用い接続するものであり、接続金具及びドレンパンとでケーシングの本体と蓋との離脱を阻止することができる。 The drain pan is attached using U-shaped connection fittings, with the plate-shaped upper side of the connection fitting on the casing top plate and both plate-shaped side sides of the connection fitting on both side plates of the casing. Bent sides with abutment arrangement and bolt insertion holes protruding outward from the lower ends of both sides, and bolt insertion holes protruding outward from the center of the upper end of the side plate facing the left and right directions of the drain pan. It aligns with the provided protruding pieces and connects them using long bolts and nuts through both insertion holes, and the connection fittings and drain pan can prevent the casing body and lid from coming off. ..

この場合、接続金具の折曲辺及びドレンパンの突出片間に肉厚のゴム座を配置し、地震時の揺れをゴム座が吸収して空気熱交換器の損傷を阻止し、長寸のボルト及びナットの過度な締付けを阻止して天板の損傷を抑止することができ、また、長寸のボルトに螺着するナットを緩めて下方に移動させれば、ドレンパンを取外すことなく排水孔及びドレンパンの清掃を容易に実施することができる。 In this case, a thick rubber seat is placed between the bent side of the connection fitting and the protruding piece of the drain pan, and the rubber seat absorbs the shaking during an earthquake to prevent damage to the air heat exchanger, and a long bolt. And it is possible to prevent excessive tightening of the nut and prevent damage to the top plate, and if the nut that is screwed to the long bolt is loosened and moved downward, the drain hole and the drain pan can be removed without removing the drain pan. The drain pan can be easily cleaned.

傾斜状配置の冷温水コイルは、吸気側の前側エンドプレートの折曲した両端側辺の下端には、ケーシングの底板上面への当接部を内方に傾斜状に折曲げして三角片を形成し、前側のエンドプレートが底板への減り込みを阻止するものであり、同様に給気側の後側エンドプレートの折曲げした両端側辺の上端には、蓋の天板下面への当接部を傾斜状に折曲げして三角片を形成し、設置安定性を確保するのが好ましい。
また、循環パイプへの熱媒入口の往き側及び熱媒出口の還り側は、ケーシング本体の両側の側板から突出形態で配置して懐が小さな天井空間上下方向の配管を回避するのが好ましい。For the cold / hot water coil arranged in an inclined shape, a triangular piece is formed by bending the abutting portion of the casing to the upper surface of the bottom plate inward at the lower ends of the bent both ends of the front end plate on the intake side. The front end plate is formed to prevent the bottom plate from being reduced. Similarly, the upper ends of the bent rear end plates on the air supply side are in contact with the lower surface of the top plate of the lid. It is preferable to bend the contact portion in an inclined shape to form a triangular piece to ensure installation stability.
Further, it is preferable that the outward side of the heat medium inlet to the circulation pipe and the return side of the heat medium outlet are arranged in a protruding form from the side plates on both sides of the casing main body to avoid piping in the vertical direction of the ceiling space having a small pocket.

また、本体の両側側板間の距離より長寸のエンドプレートは、本体の吸気側の両側板内面の高さ方向全長に亘って溝状に穿設した前切欠に、前側エンドプレートを底板上面に当接配置して嵌合し、後側のエンドプレートは、給気側の両側板内面の上端に溝状に穿設する先切欠に嵌入し、先切欠の下側に配置した、両側板から内方に突出形態の支承台に冷温水コイルの下端を載置するため、取付部材を用いずに、簡単に冷温水コイルを配置することができる。 In addition, for the end plate that is longer than the distance between the side plates on both sides of the main body, the front end plate is placed on the upper surface of the bottom plate in the front notch formed in a groove shape over the entire length of the inner surface of both side plates on the intake side of the main body in the height direction. The end plates on the rear side are fitted in contact with each other, and the end plates on the rear side are fitted into the tip notches formed in a groove shape at the upper ends of the inner surfaces of both side plates on the air supply side, and from the side plates arranged under the tip cutouts. Since the lower end of the cold / hot water coil is placed on the inwardly protruding bearing, the cold / hot water coil can be easily arranged without using a mounting member.

また、冷温水コイルの上面に配置する、両側の受板に風偏向板群を固着一体化した梯子状の風偏向具は、前側から後側に先細り状の両受板上端に、通過風量が低減する形態に厚肉（１ｍｍ）の風偏向板群を順じ差し渡し上に接合配置するものであり、受板はケーシング本体の側板内面及び冷温水コイルのフィン端部との隙間に、冷温水コイルの下端と面一形態に挿入することで、風偏向板群の下端がフィン群上面に密着されるものであって、放熱フィン群の増（従来例より２７％増）により、配置間隔を小さくし（同１４４ｍｍを１１５ｍｍに）、数を増（同４から５に）とした風偏向板群は、冷温水コイル上面から突出長さを維持して確実に傾斜立設し、吸入空気流を冷温水コイルの上面空間から下側空間に効率的に偏向案内することができる。 In addition, the ladder-shaped wind deflector, which is placed on the upper surface of the cold / hot water coil and has a group of wind deflectors fixed and integrated to the receiving plates on both sides, has a passing air volume at the upper ends of both receiving plates that taper from the front side to the rear side. A group of thick-walled (1 mm) wind deflection plates are joined and arranged on top of each other in a reduced form, and the receiving plate is placed in the gap between the inner surface of the side plate of the casing body and the fin end of the cold / hot water coil. By inserting it flush with the lower end of the coil, the lower end of the wind deflection plate group is brought into close contact with the upper surface of the fin group, and the arrangement interval is increased by increasing the heat radiation fin group (27% increase from the conventional example). The wind deflection plate group, which has been made smaller (from 144 mm to 115 mm) and increased in number (from 4 to 5), is erected reliably while maintaining the protruding length from the upper surface of the cold / hot water coil, and the intake air flow. Can be efficiently deflected and guided from the upper space of the hot / cold water coil to the lower space.

本発明の空気熱交換器は、ケーシングに、大量生産が可能で安価な発泡プラスチックの射出成型品を採用し、軽量化（ケーシング標準重量：１．３ｋｇ）によって、耐震性、作業性を向上させ、高断熱のケーシングが放熱を阻止して冷却又は加熱空気を高効率に供給ができ、両端にダクト管の接続機構を形成させてレジューサー管などの継手部材を不要とし、総長さを短縮し配置作業性を向上させるものであって、ドレンパンのメンテナンスを容易とし、組立作業を簡便にし、高性能で安価な空気熱交換器を提供するものである。 The air heat exchanger of the present invention adopts an inexpensive foamed plastic injection molded product that can be mass-produced for the casing, and improves earthquake resistance and workability by reducing the weight (casing standard weight: 1.3 kg). , Highly insulated casing blocks heat dissipation and can supply cooling or heated air with high efficiency, and duct pipe connection mechanisms are formed at both ends to eliminate the need for joint members such as reducer pipes and shorten the total length. It improves the arrangement workability, facilitates the maintenance of the drain pan, simplifies the assembly work, and provides a high-performance and inexpensive air heat exchanger.

本発明の空気熱交換器は、プラスチック保温材用の原材料を用いた射出成型品のケーシングとして軽量化（ケーシング重量：１．３ｋｇ）を図り、且つ耐震性を向上し、空気熱交換器自体からの放熱を低減して居室内に冷却又は加熱空気を高効率に供給するものであって、ケーシング内に冷温水コイルの支承部、発生する結露水の排水部、両端にダクト管を連通接続する継手部材を嵌入するための支持台を成形配置して、組立作業を容易にし、安価（図１２に示す、従来例１の空気熱交換器の略７０％）な空気熱交換器となる。 The air heat exchanger of the present invention has been reduced in weight (casing weight: 1.3 kg) as a casing of an injection-molded product using a raw material for a plastic heat insulating material, and has improved earthquake resistance, from the air heat exchanger itself. It reduces heat dissipation and supplies cooling or heated air to the living room with high efficiency. In the casing, the support part of the cold / hot water coil, the drainage part of the generated dew condensation water, and the duct pipes are connected to both ends. A support base for fitting the joint member is formed and arranged to facilitate the assembly work, resulting in an inexpensive air heat exchanger (approximately 70% of the air heat exchanger of the conventional example 1 shown in FIG. 12).

また、空気熱交換器は、コ字形状の接続金具をケーシングに冠着し、排水部の底板下面に配置するドレンパンと長ボルト（標準：１００ｍｍ）にナットを螺着して接続するものであり、長ボルト上のナットを下方移動によって、ドレンパンを取外しすることなく、排水孔及びドレンパンやドレン管の点検が容易に実施できる、メンテナンス性に優れた空気熱交換器となる。 In the air heat exchanger, a U-shaped connection fitting is attached to the casing, and a nut is screwed to a drain pan and a long bolt (standard: 100 mm) arranged on the lower surface of the bottom plate of the drainage portion. By moving the nut on the long bolt downward, the drain hole, drain pan, and drain pipe can be easily inspected without removing the drain pan, resulting in an air heat exchanger with excellent maintainability.

また、ケーシングの本体内に傾斜配置する冷温水コイルは、前側エンドプレートの両端側辺の下側と、後側エンドプレートの両端側辺の上側とをおのおの傾斜状に折曲して三角片を形成し、前側エンドプレートが当接載置する底板への減り込みを阻止し、後側エンドプレートの三角片は、蓋下面に当接し冷温水コイルの浮き揚がりを抑制して、冷温水コイルの設置安定性を確保するものであり、吸気側の溝状の前切欠に前側エンドプレートの両端を嵌合し、給気側の先切欠に後側エンドプレートの両端を挿入し、冷温水コイルの後端を支承台に傾斜載置して、前側及び後側のエンドプレートとケーシングとの当接部からの空気流出入を抑制し、冷温水コイルの上面空間から冷温水コイルの下面空間に、フィン群から熱伝達される高性能の空気熱交換器となる。 In addition, the cold / hot water coils that are inclined and arranged in the main body of the casing are bent in an inclined shape at the lower sides of both ends of the front end plate and the upper sides of both ends of the rear end plate to form a triangular piece. The triangular piece of the rear end plate abuts on the lower surface of the lid to prevent the cold / hot water coil from floating, and the cold / hot water coil is formed. To ensure installation stability, both ends of the front end plate are fitted into the groove-shaped front notch on the intake side, and both ends of the rear end plate are inserted into the front notch on the air supply side. The rear end is tilted and placed on the support base to suppress air inflow and outflow from the contact portion between the front and rear end plates and the casing, and from the upper surface space of the cold / hot water coil to the lower surface space of the cold / hot water coil. It is a high-performance air heat exchanger that transfers heat from the fins.

空気熱交換器ＨＣは、冷温水を生成する熱源機９から往き側パイプ９１を介して冷温水の供給を受け、空気熱交換器ＨＣ内に収納する冷温水コイル４の往き側４７接続パイプから熱媒を流入し、循環パイプ４１を流水し還り側４８接続パイプから流出して、還り側パイプ９２を介して熱源機９に戻水し、熱源機９で再度冷温水を生成し空気熱交換器ＨＣへの送水を繰り返して、空気熱交換器ＨＣを貫流する空気を冷却又は加熱するものであり、発生した結露水はドレンパン５のドレン管５６に連通接続した排水パイプ５７から室外に排出する（図１０（Ａ））[Use of air heat exchanger (Fig. 11)]
11A and 11B are explanatory views of an air heat exchange system, FIG. 11A is a schematic view of the system, and FIG. 11B is a vertical sectional side view in which the air heat exchanger HC is arranged in a ceiling space.
The air heat exchanger HC receives cold / hot water from the heat source machine 9 that generates cold / hot water via the outgoing pipe 91, and is housed in the air heat exchanger HC from the outgoing side 47 connection pipe of the cold / hot water coil 4. The heat medium flows in, the circulation pipe 41 flows, flows out from the return side 48 connection pipe, returns to the heat source machine 9 via the return side pipe 92, and the heat source machine 9 generates cold / hot water again to exchange air heat. Water is repeatedly sent to the vessel HC to cool or heat the air flowing through the air heat exchanger HC, and the generated dew condensation water is discharged to the outside from the drain pipe 57 communicated with the drain pipe 56 of the drain pan 5. (Fig. 10 (A))

空気熱交換器ＨＣへの空気の供給は、図１０（Ｂ）に示すように、外壁ＯＷに配置した慣用の吸気口２３からダクト管８２を介して、ファン８４の吸引押圧作用によって、天井空間内の床Ｆから吊ボルトｂ２で吊下げた空気熱交換器ＨＣに送風し、空気熱交換器ＨＣを貫流する空気は冷温水コイル４で冷却又は加熱されて、天井Ｃ面に配置した給気口８５から居室に供給するものである。また、吸気口２３及びファン８４間にフィルターを適宜配置して吸入空気に含まれる塵や埃を排除するのが良い。 As shown in FIG. 10B, the air is supplied to the air heat exchanger HC from the conventional intake port 23 arranged on the outer wall OW through the duct pipe 82 by the suction pressing action of the fan 84 to the ceiling space. Air is blown from the floor F inside to the air heat exchanger HC suspended by the hanging bolt b2, and the air flowing through the air heat exchanger HC is cooled or heated by the cold / hot water coil 4 and the air supply is arranged on the ceiling C surface. It is supplied to the living room from the mouth 85. Further, it is preferable to appropriately arrange a filter between the intake port 23 and the fan 84 to eliminate dust and dirt contained in the intake air.

本実施例の空気熱交換器ＨＣは、冷房運転時には、冷温水コイル４内に冷却水を循環させることにより、空気熱交換器ＨＣ内に流入する空気流ａ２はフィン４２群からの熱交換作用を受けて、除湿冷風ａ４として居室内に供給でき、同時に冷却作用で生じたフィン４２群の結露水は、吸気側１６から給気側１７への空気流により吸気側１６に流水することなく、防水堤２１の介在によってドレンパン５に付設するドレン管５６から支障なく排除できた。 In the air heat exchanger HC of this embodiment, the cooling water is circulated in the cold / hot water coil 4 during the cooling operation, so that the air flow a2 flowing into the air heat exchanger HC has a heat exchange action from the fins 42 group. In response to this, it can be supplied to the living room as dehumidifying cold air a4, and at the same time, the dew condensation water of the fins 42 group generated by the cooling action does not flow to the intake side 16 due to the air flow from the intake side 16 to the air supply side 17. It was possible to remove it from the drain pipe 56 attached to the drain pan 5 without any trouble by the intervention of the waterproof bank 21.

また、暖房運転時には、冷温水コイル４に加温水を循環させて、空気熱交換器ＨＣ内への吸気空気流ａ２をフィン４２群での熱交換作用で加温空気として居室内に供給できた。そして、空気熱交換器は上下左右寸法は長寸であるが、ドレン管５６は左右方向に配置するため、天井空間や床下空間のスペースの限られた場所にも簡便に設置できる。 Further, during the heating operation, the warm water was circulated through the cold / hot water coil 4, and the intake air flow a2 into the air heat exchanger HC could be supplied to the living room as warm air by the heat exchange action of the fins 42 group. .. The air heat exchanger has long vertical and horizontal dimensions, but since the drain pipe 56 is arranged in the horizontal direction, it can be easily installed even in a limited space such as a ceiling space or an underfloor space.

また、熱交換作用は、上下左右寸法（標準：縦４４ｍｍ、横２０３．２ｍｍ）の小さなフィン４２を多数長手方向に配置し、空気流を各フィン４２の上下面に、フィン４２配向面直交形態で貫流させたが、高圧空気Ｓｕでは、入口から奥へ、スペースが側面視三角形状で狹くなって、圧送空気流ａ２は、最奥では最大圧力となり、対応して、下面空間Ｓｄは低圧域となるため、圧送空気流ａ２は、間隔配置した風偏向板６０群での整流偏向作用の助力の下に、冷温水コイル４の長さ方向全長に亘って、各フィン４２間の隙間を貫通して均斉な熱交換作用を発揮した。
尚、各偏向板４２の下端は、側板１１２とフィン４２群の隙間に受板６６を挿合することで、フィン４２群の上面と密着し、各フィン４２の隙間から低圧域の下面空間Ｓｄに貫流空気流は支障なく圧送できた。Further, in the heat exchange action, a large number of small fins 42 having vertical and horizontal dimensions (standard: length 44 mm, width 203.2 mm) are arranged in the longitudinal direction, and air flow is applied to the upper and lower surfaces of each fin 42 in a form orthogonal to the fin 42 orientation plane. However, in the high-pressure air Su, the space becomes triangular in the side view from the inlet to the back, and the pumped air flow a2 becomes the maximum pressure at the innermost part, and the lower surface space Sd corresponds to the low pressure. Since it is a region, the pumping air flow a2 creates a gap between the fins 42 over the entire length of the cold / hot water coil 4 in the length direction with the help of the rectifying deflection action of the spaced wind deflection plates 60 groups. It penetrated and exhibited a uniform heat exchange action.
The lower end of each deflecting plate 42 is brought into close contact with the upper surface of the fin 42 group by inserting the receiving plate 66 into the gap between the side plate 112 and the fin 42 group, and the lower surface space Sd in the low pressure region from the gap of each fin 42. The once-through air flow could be pumped without any trouble.

また、冷温水コイル４は、溝状の両前切欠３１に前側エンドプレート４３１の両端側辺４３３を、両先切欠３２に後面エンドプレート４３２の両端側辺４３３をおのおの嵌入配置し、上方位置にある冷温水コイル４の後端を支承台３３に傾斜載置して配置するため、冷温水コイル４は取付金具を用いることなく収納装着作業及び風偏向板群の配置作業性が容易となり、組立作業面、コスト面（図１２に示す従来例の空気熱交換器の略７０％）に優れた空気熱交換器の提供ができた。 Further, in the cold / hot water coil 4, both end plate 431's both end side sides 433 are fitted into the groove-shaped both front notches 31, and both end side sides 433 of the rear end plate 432 are fitted into both end notches 32, respectively. Since the rear end of a certain cold / hot water coil 4 is placed on the support base 33 in an inclined manner, the cold / hot water coil 4 can be easily stored and mounted and the wind deflection plate group can be easily arranged without using mounting brackets. We were able to provide an air heat exchanger that is excellent in terms of work and cost (approximately 70% of the conventional air heat exchanger shown in FIG. 12).

また、空気熱交換器ＨＣのケーシング１は、耐食性、断熱性に優れる発泡プラスチックの射出成形で形成するものであり、従って、ケーシングに断熱材を貼着することなく、空気熱交換器自体からの放熱を阻止し、且つフィン４２の増量もあって、居室に高効率の冷却又は加温空気を供給することができ、本体１１及び蓋１２とは慣用の気密テープ１８の貼着で容易に気密性を保持して一体化が可能で、軽量の、耐震性に優れた空気熱交換器の提供ができた。 Further, the casing 1 of the air heat exchanger HC is formed by injection molding of foamed plastic having excellent corrosion resistance and heat insulating properties. Therefore, the air heat exchanger itself can be used without attaching a heat insulating material to the casing. Highly efficient cooling or warming air can be supplied to the living room by blocking heat dissipation and increasing the amount of fins 42, and the main body 11 and the lid 12 are easily airtight by attaching a conventional airtight tape 18. We were able to provide an air heat exchanger that is lightweight and has excellent earthquake resistance, which can be integrated while maintaining its properties.

また、本発明の空気熱交換器ＨＣは、夏期運転時において、吸気側１６から、例えば、空気温度が３５℃、湿度が７０％（絶対湿度：湿った空気の乾燥空気１ｋｇ当たりの水蒸気量（ｇ）、２５．６ｇ／ｋｇ）の空気をファン８４を介して風量１５０ｍ３／ｈで流入し、空気熱交換器ＨＣ内の冷温水コイル４に冷水温度が１０℃の熱媒を流量３．５Ｌ／ｍｉｎで送水循環すると、冷温水コイル４で１７７８ｇ／ｈの除湿がなされ、空気温度が１８．３℃、湿度が９７．６％（絶対湿度：１２．９ｇ／ｋｇ）の水蒸気量を略半減した除湿冷却空気が、放熱量が１８７６Ｗ／ｈで給気側１７から排出されるものであり、冬期運転時において、例えば、空気量、熱媒の流量が夏期運転時と同条件とし、吸気側１６から０℃の空気を流入し冷温水コイル４に温度４０℃の温水を送水循環すると、給気側１７から３０℃の加温空気が放熱量１４００Ｗで排出され、居室内の空気と混合されて快適な室内空気環境を奏することができた。Further, the air heat exchanger HC of the present invention has an air temperature of 35 ° C. and a humidity of 70% (absolute humidity: the amount of water vapor per 1 kg of dry air of moist air (absolute humidity:) from the intake side 16 during summer operation. g), 25.6 g / kg) of air flows in through the fan 84 at an air volume of 150 m 3 / h, and a heat medium having a chilled water temperature of 10 ° C. flows into the cold / hot water coil 4 in the air heat exchanger HC. When water is sent and circulated at 5 L / min, the cold / hot water coil 4 dehumidifies 1778 g / h, and the amount of water vapor with an air temperature of 18.3 ° C and a humidity of 97.6% (absolute humidity: 12.9 g / kg) is omitted. The dehumidified cooling air that has been halved is discharged from the air supply side 17 with a heat dissipation amount of 1876 W / h. During winter operation, for example, the amount of air and the flow rate of the heat medium are the same as those during summer operation, and intake is performed. When air at 0 ° C. flows in from the side 16 and hot water at a temperature of 40 ° C. is sent and circulated to the cold / hot water coil 4, warm air at 30 ° C. is discharged from the air supply side 17 with a heat dissipation amount of 1400 W and mixed with the air in the living room. It was possible to create a comfortable indoor air environment.
