Description

この考案は、加温した空気を室内に吹き込むようにして、温室などの暖房をするに際し、加温効率の向上を目的とした熱交換器及び温風暖房装置に関する。   The present invention relates to a heat exchanger and a hot air heater for the purpose of improving the heating efficiency when heating a greenhouse or the like by blowing warm air into a room.

従来、室内空気を加温する際、ガス又は燈油などの燃焼熱を利用する方式にあっては、温風機を室内に設置し、温風機内へ室内空気を通過させて熱交換させることが一般的に行なわれている。   Conventionally, when heating indoor air, in a method using combustion heat such as gas or fuel oil, it is common to install a hot air fan indoors and let the indoor air pass through the hot air fan to exchange heat. Has been done.

前記温風機で加温された空気は、送風ダクトによって、室内適所に導かれ、複数の吹出口から吹き出して、対流させつつ加温するのが普通である。   Usually, the air heated by the hot air fan is guided to a suitable place in the room by a blower duct, blown out from a plurality of air outlets, and heated while being convected.

近来エネルギーの効率的利用として、燃焼煙の排熱を利用して、燃焼室へ送り込む空気を加温（燃焼効率の向上）したり、煙筒に熱交換器を付設したりすること（排熱利用）も提案されている。
特開２００３−２７９００５号 特許第３６２７２１６号 For efficient use of near-field energy, use the exhaust heat of combustion smoke to heat the air sent to the combustion chamber (improving combustion efficiency) or attach a heat exchanger to the smoke cylinder (use of exhaust heat) ) Has also been proposed.
JP 2003-279005 A Japanese Patent No. 3627216

温風暖房機において熱効率を向上させる為に、排ガスの一部を燃焼用空気と混合させる提案がある（特許文献１）。また温風暖房機に、排熱回収ユニットを設置して熱効率を向上させる発明の提案がある（特許文献２）。   In order to improve thermal efficiency in a warm air heater, there is a proposal of mixing a part of exhaust gas with combustion air (Patent Document 1). In addition, there is a proposal of an invention for improving the thermal efficiency by installing an exhaust heat recovery unit in a warm air heater (Patent Document 2).

前記発明は、燃焼効率の向上又は排熱の有効利用などを目的とするもので、夫々有効であるとされており、前記両者を兼ねるような装置の可能性もある。   The invention is aimed at improving combustion efficiency or effectively using exhaust heat, and is considered to be effective, and there is a possibility of an apparatus that serves as both.

然し乍ら、前記各発明は、燃焼器又は温風機自体の発明であって、新しい器機の提案であるから、使用者にすれば、既設の設備を買い換え、又は大改造しなければならない問題点がある。   However, each of the above-mentioned inventions is an invention of a combustor or a warm air machine itself, and is a proposal of a new equipment. Therefore, for a user, there is a problem that an existing facility has to be replaced or largely remodeled. .

また排煙利用の熱交換器であっても、加温すべき空気を吸入し、加温後これを吹き出す為のファンを必須条件としている問題点があった。   Further, even in a heat exchanger utilizing smoke, there is a problem that a fan for inhaling air to be heated and blowing it out after heating is an essential condition.

然るにこの考案は、温風ダクトの吹出し力を利用して、熱交換器内の流動力を得るので、流動用ファンを設置することなく、前記従来の問題点を解決したのである。   However, the present invention solves the above-mentioned conventional problems without installing a flow fan because the flow force in the heat exchanger is obtained by utilizing the blowing force of the hot air duct.

即ちこの考案は、器体の上部内側へ上煙室を設け、器体の下部内側へ下煙室を設け、前記上煙室の底板と、前記下煙室の頂板との間の熱交換室へ複数の管体を連結開口して、上下両煙室を連結し、前記上下煙室へ、煙筒を夫々連設すると共に、前記熱交換室の一方の壁へ連結ダクトの連結部を設け、他方の壁へ温風吹出し筒を連設したことを特徴とする熱交換器であり、器体の上部内側へ上煙室を設け、器体の下部内側へ下煙室を設け、前記上煙室の底板と、前記下煙室の頂板との間の熱交換室へ複数の管体を連結開口して、上下両煙室を連結し、前記管体の外側へ夫々多数のフィンを設置し、前記上下煙室へ、煙筒を夫々連設すると共に、前記熱交換室の一方の壁へ連結ダクトの連結部を設け、他方の壁へ温風吹出し筒を連設したことを特徴とする熱交換器であり、器体の上部内側へ上煙室を設け、器体の下部内側へ下煙室を設け、前記上煙室の底板と、前記下煙室の頂板との間の熱交換室へ複数の管体を連結開口して、上下両煙室を連結し、前記管体の外側へ夫々多数のフィンを設置し、前記上下煙室へ、煙筒を夫々連設すると共に、前記熱交換室の一方の壁へ、連結ダクトの吹込口を設け、他方の壁へ温風吹出し筒を連設したことを特徴とする熱交換器である。また、熱交換器と連結ダクトとの連結は、密接連結又は連結ダクトの先端ノズルを、熱交換器の連結孔に遊嵌したものである。   That is, this device is provided with an upper smoke chamber inside the upper body, a lower smoke chamber inside the lower body, and a heat exchange chamber between the bottom plate of the upper smoke chamber and the top plate of the lower smoke chamber. A plurality of pipes are connected and opened to connect the upper and lower smoke chambers, and smoke tubes are connected to the upper and lower smoke chambers, respectively, and a connecting duct connecting portion is provided on one wall of the heat exchange chamber, A heat exchanger characterized in that a hot air blowing tube is continuously connected to the other wall, an upper smoke chamber is provided inside the upper part of the vessel, a lower smoke chamber is provided inside the lower part of the vessel, and the upper smoke A plurality of tubes are connected to the heat exchange chamber between the bottom plate of the chamber and the top plate of the lower smoke chamber, the upper and lower smoke chambers are connected, and a large number of fins are installed on the outside of the tube. In addition, a smoke tube is continuously connected to the upper and lower smoke chambers, a connecting duct connecting portion is provided on one wall of the heat exchange chamber, and a hot air blowing tube is continuously connected to the other wall. The upper smoke chamber is provided inside the upper part of the vessel body, the lower smoke chamber is provided inside the lower part of the vessel body, and between the bottom plate of the upper smoke chamber and the top plate of the lower smoke chamber. Connecting and opening a plurality of tubes to the heat exchange chamber, connecting the upper and lower smoke chambers, installing a large number of fins on the outside of the tube, and connecting smoke tubes to the upper and lower smoke chambers, respectively, The heat exchanger is characterized in that a connection duct blow-in port is provided on one wall of the heat exchange chamber, and a hot air blowing tube is continuously provided on the other wall. In addition, the connection between the heat exchanger and the connection duct is a close connection, or the tip nozzle of the connection duct is loosely fitted in the connection hole of the heat exchanger.

また他の考案は、温風機の温風ダクトの中間部と、煙筒に設置した請求項１又は２記載の熱交換器の吸入口とを連結ダクトで連結したことを特徴とする温風暖房装置であり、温風機の温風吹出し筒の一つと、煙筒に設置した請求項１又は２記載の熱交換器の吸入口とを連結ダクトで連結したことを特徴とする温風暖房装置である。   According to another aspect of the present invention, there is provided a warm air heating apparatus characterized in that an intermediate portion of a warm air duct of a warm air machine is connected to a suction port of a heat exchanger according to claim 1 or 2 installed in a smoke cylinder by a connection duct. A hot air heating apparatus characterized in that one of the hot air blowing tubes of the hot air machine and the intake port of the heat exchanger according to claim 1 or 2 installed in the smoke tube are connected by a connecting duct.

更に他の考案は、温風機の温風生成室の右又は左に吹出管を設け、該吹出管と、煙筒に介装した請求項１、２又は３記載の熱交換器の吸入口とを連結ダクトで連結したことを特徴とする温風暖房装置であり、温風機の温風ダクトの中間部と、煙筒に介装した請求項１、２又は３記載の熱交換器の吸入口とを連結ダクトで連結し、前記温風ダクトの連結ダクト連結部の両側にダンパーを設けたものである。   In another aspect of the present invention, a blow pipe is provided on the right or left of the warm air generation chamber of the warm air machine, and the blow pipe and the suction port of the heat exchanger according to claim 1, 2 or 3 interposed in the smoke cylinder. It is a hot air heating device characterized by being connected by a connecting duct, comprising: an intermediate part of a hot air duct of a hot air machine; and a suction port of a heat exchanger according to claim 1, 2 or 3 interposed in a smoke cylinder. It connects with a connection duct, A damper is provided in the both sides of the connection duct connection part of the said warm air duct.

前記において、熱交換器はファンが不用であるから、これに伴うモータ及び回転羽根その他が不必要となると共に、構造が簡易化し、軽量、低廉化する利点がある。   In the above, since the heat exchanger does not require a fan, the motor and the rotating blades associated therewith are unnecessary, and there is an advantage that the structure is simplified and the weight and cost are reduced.

前記温風暖房装置によれば、温風の吹出しと、熱交換器からの吹出しと、温風の熱対流（温度の高い空気が上昇する）により、室内温度を均一化することができる。大きい温室には、室内空気の流動用ファンを複数設置するのが普通であるが、この考案を使用し、吹出し口の位置を適切に配置すれば、前記流動用ファンの数を削減し、又は皆無にすることも可能である。   According to the warm air heating device, the room temperature can be made uniform by blowing hot air, blowing from the heat exchanger, and heat convection of hot air (air having a high temperature rises). In a large greenhouse, it is common to install a plurality of indoor air flow fans, but if this device is used and the position of the outlet is appropriately arranged, the number of flow fans can be reduced, or It is also possible to eliminate it.

また温風吹出し口に、適切な案内を付設し、室内空気に流動力を与え、強制流動させることもできる。   In addition, an appropriate guide can be attached to the hot air outlet to apply a fluid force to the indoor air to cause forced flow.

この考案によれば、既設の設備を有効利用し、又は、ファンのない熱交換器を設置して、温室の暖房を高い熱効率で行うことができる効果がある。   According to this device, there is an effect that heating of the greenhouse can be performed with high thermal efficiency by effectively using existing facilities or installing a heat exchanger without a fan.

また既設の設備をそのまま利用して（連結ダクトの新設のみ）、熱効率を向上し得る効果がある。   Moreover, there is an effect that the existing equipment can be used as it is (only a new connection duct is installed) to improve the thermal efficiency.

また新設の場合には、軽量、かつ低廉なファンなし熱交換器により、同等以上の熱効率を向上し得る効果がある。   In addition, in the case of a new installation, there is an effect that a heat efficiency equal to or higher than that can be improved by a light and inexpensive heat exchanger without a fan.

温風機の温風ダクトの中間部と、煙筒に設置した熱交換器の吸入口とを連結ダクトで連結した。従って連結ダクト内を流動する温風の一部が、熱交換器に吸入され（強制的に吹き込む）、熱交換されて昇温熱風となって室内へ吹き出される。前記において、温風ダクト内の温風の一部（例えば４９℃）が熱交換器に吹き込まれ、６２．２℃になって吹き出されると、１３．２℃の回収温度差が見込まれる。   The intermediate part of the warm air duct of the warm air machine and the suction port of the heat exchanger installed in the smoke cylinder were connected by a connecting duct. Therefore, a part of the warm air flowing in the connecting duct is sucked into the heat exchanger (forcibly blown), is heat-exchanged and blown into the room as heated hot air. In the above, when a part of the warm air in the warm air duct (for example, 49 ° C.) is blown into the heat exchanger and blown to 62.2 ° C., a recovery temperature difference of 13.2 ° C. is expected.

前記回収温度差は、温風の温度、吹き込み量（例えば１８．８ｍ３／ｍｉｎ）及び煙温度によって大差がある。 The recovery temperature difference varies greatly depending on the temperature of hot air, the amount of blowing (for example, 18.8 m 3 / min) and the smoke temperature.

然し乍ら一般論としては、煙温度と吹込み空気との温度差及び風量により異なるが、温度差が大きく、風量が多い方が回収熱総量は多くなる。   However, as a general theory, although it differs depending on the temperature difference between the smoke temperature and the blown air and the air volume, the larger the temperature difference and the larger the air volume, the larger the total recovered heat.

この考案の実施例を図１（ａ）について説明すると、温風機１の温風ダクト２の基部へ、連結ダクト３の基部を連結し、前記連結ダクト３の先端部を熱交換器５の吸込み口４へ連結する。   Referring to FIG. 1 (a), an embodiment of the present invention will be described. The base of the connecting duct 3 is connected to the base of the hot air duct 2 of the warm air machine 1, and the tip of the connecting duct 3 is sucked into the heat exchanger 5. Connect to mouth 4.

前記実施例において温風機１の温風ダクト２に温風を矢示６、６のように送ると、連結ダクト３にも矢示７のように送られ、そのまま流動して、熱交換器５の吸込み口４から、矢示８のように熱交換器５内へ入る。熱交換器５内の上下には煙室９、９ａが設けられ、前記煙室９、９ａの間を円管１０、１０で連通させ、円管１０、１０の外側へ突設した多数のフィン１０ａによって、熱効率を向上させて、矢示１８、１９のように室内へ放出される。   In the above embodiment, when warm air is sent to the warm air duct 2 of the warm air machine 1 as indicated by arrows 6 and 6, it is also sent to the connecting duct 3 as indicated by arrow 7 and flows as it is, and the heat exchanger 5 Then, the air enters the heat exchanger 5 as indicated by an arrow 8. Smoke chambers 9, 9 a are provided above and below in the heat exchanger 5, and the smoke chambers 9, 9 a are communicated with each other by circular tubes 10, and a large number of fins projecting to the outside of the circular tubes 10, 10. The thermal efficiency is improved by 10a, and it is discharged into the room as indicated by arrows 18 and 19.

一方煙筒１１内の排ガスは、矢示１２、１３、１４のように上昇する。この際円管１０及びフィン１０ａにより煙の排熱が回収される。図中２１はバーナー、２２は換気扇である。   On the other hand, the exhaust gas in the stack 11 rises as indicated by arrows 12, 13, and 14. At this time, the exhaust heat of the smoke is recovered by the circular tube 10 and the fin 10a. In the figure, 21 is a burner, and 22 is a ventilation fan.

前記のようにして、ダクト内を流動する温風を連結ダクト３で分岐して、熱交換器５へ吹き込むので、熱交換器５に吸気する為の吸入ファンが不必要となる。   As described above, since the warm air flowing in the duct is branched by the connecting duct 3 and blown into the heat exchanger 5, a suction fan for sucking the heat exchanger 5 becomes unnecessary.

前記実施例において、図２（ｃ）のように、連結ダクト３の先端部に、ノズル１５を連結し、ノズル１５を、熱交換器５の吸込み口４の中央部へ臨ませると、前記ノズル１５から矢示８のように吹き出す温風が、室内空気を、矢示１６、１７、１８のように熱交換器５内へ吸い込むことになるので、熱交換器５では、連結ダクト３からの温風（例えば５０℃）と室内空気（例えば２５℃）との混合気体（例えば３３℃、温風１に対し、室内空気２の割合とすれば）となって熱交換される。この場合における熱交換効率は、温度差の大きい程、高いので、排ガスの熱を、より多く回収することができる。   In the embodiment, as shown in FIG. 2C, when the nozzle 15 is connected to the tip of the connection duct 3 and the nozzle 15 faces the central portion of the suction port 4 of the heat exchanger 5, the nozzle Since the warm air blown out from 15 as indicated by an arrow 8 sucks indoor air into the heat exchanger 5 as indicated by arrows 16, 17 and 18, in the heat exchanger 5, from the connecting duct 3 Heat exchange is performed as a mixed gas of hot air (for example, 50 ° C.) and indoor air (for example, 25 ° C.) (for example, 33 ° C., if the ratio of indoor air 2 to hot air 1 is set). Since the heat exchange efficiency in this case is higher as the temperature difference is larger, more heat of the exhaust gas can be recovered.

この考案の他の実施例を図１（ｂ）について説明すると、温風機１の複数の吹出し筒２０ａ、２０ｂ、２０ｃ中の１つ、２０ｃに連結ダクト３の基端を連結し、前記連結ダクト３の先端部を熱交換器５に連結する。   Referring to FIG. 1B, another embodiment of the present invention will be described. One of the plurality of blowing tubes 20a, 20b, and 20c of the warm air blower 1 is connected to the base end of the connecting duct 3 to 20c. 3 is connected to the heat exchanger 5.

前記熱交換器５は、実施例１と同様に、排ガスが煙筒１１内を上昇し、円管１０と、フィン１０ａにより熱交換され、加温空気は室内へ放出され、排ガスは煙筒１１ａから矢示１４のように外界へ放出される。   In the heat exchanger 5, as in the first embodiment, the exhaust gas rises in the smoke cylinder 11, heat is exchanged by the circular tube 10 and the fin 10a, the heated air is discharged into the room, and the exhaust gas is discharged from the smoke cylinder 11a. As shown in FIG. 14, it is discharged to the outside.

前記実施例における熱回収は、実施例１と同一に付、詳細な説明は省略する。   The heat recovery in the above embodiment is the same as that in the first embodiment, and detailed description is omitted.

この発明の他の実施例を図３、４について説明すると、温風機１の温風生成室の左又は右に吹出管２４又は２４ａを設け、この吹出管２４又は２４ａに連結ダクト３の基端部を接続し、連結ダクト３の先端部を熱交換器５の吸込み口４に接続したもので、図中２３は制御器である。   3 and 4, a blow pipe 24 or 24 a is provided on the left or right of the hot air generation chamber of the warm air machine 1, and the base end of the connecting duct 3 is provided on the blow pipe 24 or 24 a. Are connected to each other, and the leading end of the connecting duct 3 is connected to the suction port 4 of the heat exchanger 5, in which 23 is a controller.

前記実施例において、温風生成室の温風は、吹出管２４から矢示２５のように連結ダクト３を経て熱交換器５に入り、熱交換して矢示２６のように室内へ放出される。   In the said Example, the warm air of a warm air production | generation chamber enters into the heat exchanger 5 through the connection duct 3 as shown by the arrow 25 from the blowing pipe 24, heat-exchanges, and is discharge | released indoors like the arrow 26.
