Description
本発明は、空調機の空気を熱交換する熱交換器に関する。
This invention relates to the heat exchanger which heat-exchanges the air of an air conditioner.
従来より、地域熱供給事業者から熱供給を受ける需要家では、熱供給事業者への熱媒温度差を確保するために、ブリードイン方式を採用する場合がある。このブリードイン方式では、需用者が利用した後の熱媒の一部を、送られてきた熱媒と混合弁などで混合して、熱媒温度を確保する方式であるにも関わらず、外気条件や需要家の空調制御システムによっては、還水温度が設計値よりも低下することが知られている。また、個別熱源システムの場合でも同じことが知られている。
Conventionally, a consumer who receives heat supply from a district heat supply company may adopt a bleed-in method in order to secure a heat medium temperature difference to the heat supply company. In this bleed-in method, a part of the heat medium used by the customer is mixed with the sent heat medium with a mixing valve, etc., to ensure the heat medium temperature, It is known that the return water temperature is lower than the design value depending on the outside air condition and the customer's air conditioning control system. The same is also known for individual heat source systems.

このため、特許文献1に開示されているような空調システムを提案されている。この技術は、ファンコイル装置Aの熱交換器に冷温水を循環供給するとともに、この熱交換器に外気及び室内空気を通過させることにより冷温水と空気とを熱交換させ、熱交換器に接続した還水配管の冷温水温度を検出し、この冷温水温度が所定温度となるように熱交換器を通過させる冷温水の量を増減制御し、一方、熱交換器を迂回するバイパス路を設けて、このバイパス路には熱交換器を迂回する空気量を可変にするバイパス風量可変ダンパを配置し、検出器により、空調空間内の温度、空調空間への給気温度などの当該空調システムの制御対象量を検出し、その検出値に応じて、バイパス風量可変ダンパを制御して、熱交換器を通過した空気が所望温度となるようにしており、結果、バイパス路を通過する空気量と熱交換器を通過する空気量との比率を制御することになる。 When the temperature difference of the heat medium cannot be ensured, there is a large amount of water required by customers, which may lead to insufficient heat supply to other customers. In addition, the energy consumption increases due to the increase in pump conveyance power and the number of operating refrigerators.
For this reason, an air conditioning system as disclosed inPatent Document 1 has been proposed. This technology circulates and supplies cold / hot water to the heat exchanger of the fan coil device A, and allows the cold / hot water and air to exchange heat by passing outside air and indoor air through the heat exchanger, and connects to the heat exchanger. The temperature of the cool / warm water in the return water pipe is detected, and the amount of cool / warm water passing through the heat exchanger is controlled to increase or decrease so that the cool / warm water temperature becomes a predetermined temperature, while a bypass is provided to bypass the heat exchanger. In this bypass path, a bypass air volume variable damper that varies the amount of air that bypasses the heat exchanger is arranged, and the detector detects the temperature of the air conditioning system, such as the temperature in the air conditioned space and the supply air temperature to the air conditioned space. The amount of control target is detected, and the bypass air volume variable damper is controlled according to the detected value so that the air passing through the heat exchanger has a desired temperature, and as a result, the amount of air passing through the bypass path and Go through heat exchanger It will control the ratio of the air amount.
このため、特許文献1に開示されているような空調システムを提案されている。この技術は、ファンコイル装置Aの熱交換器に冷温水を循環供給するとともに、この熱交換器に外気及び室内空気を通過させることにより冷温水と空気とを熱交換させ、熱交換器に接続した還水配管の冷温水温度を検出し、この冷温水温度が所定温度となるように熱交換器を通過させる冷温水の量を増減制御し、一方、熱交換器を迂回するバイパス路を設けて、このバイパス路には熱交換器を迂回する空気量を可変にするバイパス風量可変ダンパを配置し、検出器により、空調空間内の温度、空調空間への給気温度などの当該空調システムの制御対象量を検出し、その検出値に応じて、バイパス風量可変ダンパを制御して、熱交換器を通過した空気が所望温度となるようにしており、結果、バイパス路を通過する空気量と熱交換器を通過する空気量との比率を制御することになる。 When the temperature difference of the heat medium cannot be ensured, there is a large amount of water required by customers, which may lead to insufficient heat supply to other customers. In addition, the energy consumption increases due to the increase in pump conveyance power and the number of operating refrigerators.
For this reason, an air conditioning system as disclosed in
また、熱交換器(コイル)の返り水温が所定の温度になるよう、水量コントロールを行った場合、熱交換器の出口空気温度が成り行きとなり、空調機の温度制御に不都合が生じたり、また、低負荷時には制御しきれない場合があり、水温差が確保できない状態が発生するので、本出願人らは特許文献2に開示されるいるように、熱交換器のコイル出口空気温度制御の対応手段として、熱交換器であるコイルにバイパス路を設け、コイル通過風量とバイパス風量を混合制御することによって、コイル出口空気温度を一定にし、水量制御によってコイル出口水温を所定の温度になるよう制御するバイパスダンパ方式の空調システムが提案されている。
In addition, when the water amount is controlled so that the return water temperature of the heat exchanger (coil) becomes a predetermined temperature, the air temperature at the outlet of the heat exchanger becomes undesired, resulting in inconvenience in the temperature control of the air conditioner, Since there is a case where the control cannot be performed at a low load and the water temperature difference cannot be secured, the applicants, as disclosed in Patent Document 2, correspond to means for controlling the coil outlet air temperature of the heat exchanger. As described above, a bypass path is provided in the coil which is a heat exchanger, and the coil outlet air volume and the bypass air volume are mixed and controlled so that the coil outlet air temperature is constant and the coil outlet water temperature is controlled to be a predetermined temperature by the water amount control. A bypass damper type air conditioning system has been proposed.
しかしながら、上記先行技術の空調機の熱交換器のコイル出口水温を制御した場合でも、低負荷時にコイル出口温度が所定の温度にならず、水温差が確保出来ない場合があるといった問題点があった。
また、熱交換器のコイル面積の他にバイパス用ダンパの面積が必要となり、空調機としての寸法が、通常に比べ大きくなるといった問題点があった。
本発明は、上記の問題点に鑑みてなされたもので、バイパス路やバイパスダンパが必要なく、簡単な構成で必要な空調と、コイル出口水温を所定の温度になるよう制御することができる空調機の熱交換器を提供することにある。 However, even when the coil outlet water temperature of the heat exchanger of the above prior art air conditioner is controlled, there is a problem that the coil outlet temperature does not become a predetermined temperature at a low load and the water temperature difference may not be secured. It was.
In addition to the coil area of the heat exchanger, the area of the bypass damper is required, and the size of the air conditioner is larger than usual.

本発明の空調機の熱交換器の実施例を図面に沿って説明する。
An embodiment of a heat exchanger for an air conditioner according to the present invention will be described with reference to the drawings.
本発明の熱交換器1の全体の概略を図1で説明するが、熱交換器1(コイル)は、上下方向に延びる管状の入口ヘッダ2と、同様に上下方向に延びる管状の出口ヘッダ3とが対向して設けられ、この対応する入口ヘッダ2と出口ヘッダ3と間には、熱媒を通過させて熱交換する複数の通水主管4が上下方向に複数段架け渡されている。
この複数の熱交換の為の通水主管4は、入口ヘッダ2の接続部21と出口ヘッダ3の接続部31を介して接続され、出口ヘッダ3は上端部351との下端部352で密封され、下端部近傍には出口部33が設けられ、通水主管4自体は熱交換効率を向上させるため為に放熱フィン42が設けられている。
ここで、図2、図3、図4に沿って、本発明の特徴で1つである通水主管制御機構5を説明するが、この通水主管制御機構5は、熱媒を通過させる通水主管4と、熱媒を遮断する通水主管4とを選別するもので、通水主管4の数を制御するものである。 An overall outline of theheat exchanger 1 of the present invention will be described with reference to FIG. 1. The heat exchanger 1 (coil) includes a tubular inlet header 2 extending in the vertical direction and a tubular outlet header 3 extending in the vertical direction as well. And a plurality of water flow main pipes 4 passing through a heat medium and exchanging heat are spanned between the corresponding inlet header 2 and outlet header 3 in the vertical direction.
The plurality of water flowmain pipes 4 for heat exchange are connected via a connection portion 21 of the inlet header 2 and a connection portion 31 of the outlet header 3, and the outlet header 3 is sealed by a lower end portion 352 with an upper end portion 351. In the vicinity of the lower end, an outlet 33 is provided, and the water flow main pipe 4 itself is provided with heat radiation fins 42 in order to improve heat exchange efficiency.
Here, the water mainpipe control mechanism 5 which is one of the features of the present invention will be described with reference to FIGS. 2, 3, and 4. The water main pipe control mechanism 5 is configured to pass the heat medium. The water main pipe 4 and the water main pipe 4 that blocks the heat medium are selected, and the number of water main pipes 4 is controlled.
この複数の熱交換の為の通水主管4は、入口ヘッダ2の接続部21と出口ヘッダ3の接続部31を介して接続され、出口ヘッダ3は上端部351との下端部352で密封され、下端部近傍には出口部33が設けられ、通水主管4自体は熱交換効率を向上させるため為に放熱フィン42が設けられている。
ここで、図2、図3、図4に沿って、本発明の特徴で1つである通水主管制御機構5を説明するが、この通水主管制御機構5は、熱媒を通過させる通水主管4と、熱媒を遮断する通水主管4とを選別するもので、通水主管4の数を制御するものである。 An overall outline of the
The plurality of water flow
Here, the water main
図2において、入口ヘッダ2の下端側22は、熱媒である冷水又は温水が供給される入口部23が設けられ、前記複数の通水主管4の入口側開口41が入口ヘッダ2の内壁24に上下方向に配列され、入口ヘッダ2の内壁24には液密で上下動するピストン51が配置されている。このピストン51が上下動することによって熱媒の進入を許容或いは阻止するが、図2では、下側の3本の通水主管4は熱媒に対して入口側開口41が開口し、それより上側は熱媒の進入を遮断した状態にある。
図3、図4に示すように、ピストン51は外側にはゴム製のOリング52が嵌められて液密に維持されており、ピストン51の中央部に貫通する雌ねじを設けた雌ねじ部材53が固定ボルト531によって固着され、入口ヘッダ2の管内25の上下方向に設けられた雌ねじ部材53に対応する雄ねじのネジ軸54が設けられ、ピストン51の平面部511にピストン回り止めの為の貫通孔55を設け、貫通孔55を貫通する固定シャフト56を管内25の上端部251と下端部252に固定して設けられている。
したがって、雄ねじのネジ軸54が回動することにより、ピストン51が回動しないので、雌ねじ部材53及びピストン51が管内25を上下動することになる。このネジ軸54の回転は、入口ヘッダ2の上端251の上面にある制御されるモータ57により駆動されている。 In FIG. 2, thelower end side 22 of the inlet header 2 is provided with an inlet portion 23 to which cold water or hot water as a heat medium is supplied, and the inlet side openings 41 of the plurality of water flow main pipes 4 are the inner walls 24 of the inlet header 2. The piston 51 is arranged on the inner wall 24 of the inlet header 2 and moves up and down in a liquid-tight manner. The piston 51 moves up and down to allow or prevent the heat medium from entering, but in FIG. 2, the lower three water flow main pipes 4 have an inlet side opening 41 opened to the heat medium. The upper side is in a state where the entrance of the heat medium is blocked.
As shown in FIGS. 3 and 4, thepiston 51 is fitted with a rubber O-ring 52 on the outer side to be kept fluid-tight, and a female screw member 53 provided with a female screw penetrating the central portion of the piston 51 is provided. A male screw shaft 54 that is fixed by a fixing bolt 531 and that corresponds to the female screw member 53 provided in the vertical direction of the pipe 25 of the inlet header 2 is provided, and a through-hole for preventing rotation of the piston in the flat portion 511 of the piston 51. 55, and a fixed shaft 56 penetrating the through hole 55 is fixed to the upper end 251 and the lower end 252 of the pipe 25.
Accordingly, since thepiston 51 does not rotate when the screw shaft 54 of the male screw rotates, the female screw member 53 and the piston 51 move up and down in the pipe 25. The rotation of the screw shaft 54 is driven by a controlled motor 57 on the upper surface of the upper end 251 of the inlet header 2.
図3、図4に示すように、ピストン51は外側にはゴム製のOリング52が嵌められて液密に維持されており、ピストン51の中央部に貫通する雌ねじを設けた雌ねじ部材53が固定ボルト531によって固着され、入口ヘッダ2の管内25の上下方向に設けられた雌ねじ部材53に対応する雄ねじのネジ軸54が設けられ、ピストン51の平面部511にピストン回り止めの為の貫通孔55を設け、貫通孔55を貫通する固定シャフト56を管内25の上端部251と下端部252に固定して設けられている。
したがって、雄ねじのネジ軸54が回動することにより、ピストン51が回動しないので、雌ねじ部材53及びピストン51が管内25を上下動することになる。このネジ軸54の回転は、入口ヘッダ2の上端251の上面にある制御されるモータ57により駆動されている。 In FIG. 2, the
As shown in FIGS. 3 and 4, the

ここで、熱交換器1は、排出側配管26には熱交換器(コイル)1の出口水温センサー(T1)11が配置され、この出口水温センサー(T1)11の検出値により電動二方弁12を制御して熱交換器1の入力の水量を制御し、更に、熱交換器1の下流にも温度センサー(T2)13が配置され、この温度センサー(T2)13の検出値によりモータ57の回転量を制御する。 Here, the use state of theheat exchanger 1 of the said Example 1 is demonstrated with the air conditioner 6 along FIG.
In theair conditioner 6, the air that has taken in the outside air OA and the return air RA and has passed through the filter 61 is introduced into the heat exchanger 1 of the first embodiment. The air conditioned by the heat exchanger 1 is sent to a variable air volume control device (VAV) 63 by a fan 62. The variable air volume control device (VAV) 63 controls the air volume by a room temperature sensor (T3) 14 in the living room 7. The room temperature is appropriate, and this air is blown into the living room 7 to supply air SA.
Here, in theheat exchanger 1, an outlet water temperature sensor (T 1) 11 of the heat exchanger (coil) 1 is arranged in the discharge side pipe 26, and an electric two-way valve is detected by a detection value of the outlet water temperature sensor (T 1) 11. 12 is used to control the amount of water input to the heat exchanger 1, and a temperature sensor (T 2) 13 is also arranged downstream of the heat exchanger 1, and the motor 57 is detected by the detected value of the temperature sensor (T 2) 13.

このような構成であるので、(A)入口ヘッダ2の通水段数制御機構5を制御することで、熱媒が遮断されている通水主管4は熱交換器1の通風してバイパス機能を有する。
したがって、図1で通水主管4に熱媒である冷暖房水が導入されいるグレーのエリヤが冷暖房エリヤであり、通水主管4に冷暖房水が遮断されている無色エリヤがバイパスエリヤである。
このように、出口温度センサー13の検出温度は、熱媒を遮断する通水主管を増減することで、所定の温度に調整することができる。
一方で、(A)入口水温センサー(T0)15と出口水温センサー(T1)11との温度差が大きい場合は、電動二方弁(MV)12を開くことで通水量を増やし、出口水温センサー11の温度を求められる所定の温度まで下げる。逆に、入口水温センサー(T0)15と出口水温センサー(T1)11との温度差が小さい場合には、通水する通水主管4の本数を減らして、1本当たりの通水量はそのままで所定の温度にする。
このように、熱媒である冷暖房水が遮断されている通水主管4は、前掲の特許文献2におけるダンパとバイパス路と同等の機能を有することになる。 Since it is such a structure, (A) By controlling the water flow stagenumber control mechanism 5 of the inlet header 2, the water flow main pipe 4 in which the heat medium is blocked is ventilated by the heat exchanger 1 and has a bypass function. Have.
Therefore, in FIG. 1, the gray area where the cooling / heating water as the heating medium is introduced into the water flowmain pipe 4 is the cooling / heating area, and the colorless area where the cooling / heating water is blocked in the water flow main pipe 4 is the bypass area.
Thus, the detection temperature of theoutlet temperature sensor 13 can be adjusted to a predetermined temperature by increasing or decreasing the water flow main pipe that blocks the heat medium.
On the other hand, when the temperature difference between the (A) inlet water temperature sensor (T0) 15 and the outlet water temperature sensor (T1) 11 is large, the electric water flow rate is increased by opening the electric two-way valve (MV) 12, and the outlet water temperature sensor The temperature of 11 is lowered to the required temperature. On the other hand, when the temperature difference between the inlet water temperature sensor (T0) 15 and the outlet water temperature sensor (T1) 11 is small, the number of watermain pipes 4 to be passed is reduced and the water flow rate per bottle remains as it is. Set to a predetermined temperature.
Thus, the water flowmain pipe 4 in which the cooling / heating water as the heat medium is blocked has the same functions as the damper and the bypass in Patent Document 2 described above.

On the other hand, when the temperature difference between the (A) inlet water temperature sensor (T0) 15 and the outlet water temperature sensor (T1) 11 is large, the electric water flow rate is increased by opening the electric two-way valve (MV) 12, and the outlet water temperature sensor The temperature of 11 is lowered to the required temperature. On the other hand, when the temperature difference between the inlet water temperature sensor (T0) 15 and the outlet water temperature sensor (T1) 11 is small, the number of water

なお、図1において、ピストン51と上端部251とは閉鎖されているので、上位の通水主管4に出口ヘッダ3から熱媒の水が進入することは実質的になく、必要であれば、出口ヘッダ3の開口311に逆止弁等を設ければよい。 The bypass air volume of the coil is controlled by this water flow stage number control mechanism. When the controllable range is exceeded, for example, when the required water volume becomes excessive due to a thermal load exceeding the design condition, (B) preferentially The electric two-way valve (MV) 12 can be controlled so that the outlet water temperature becomes a predetermined temperature.
Normally, (B) is operated with priority, but (A) and (B) may be appropriately combined for operation.
However, in this embodiment, the embodiment in which the control mechanism is provided in the inlet header has been described. However, a water flow stage number control mechanism may be provided in the outlet header, and the main point is that theinlet header 2 and the outlet header 3 are hung. It is only necessary to be able to control the number of pipes through which water is passed in the plurality of water main pipes 4.
In addition, in FIG. 1, since thepiston 51 and the upper end part 251 are closed, the water of the heating medium does not substantially enter the upper water flow main pipe 4 from the outlet header 3, and if necessary, A check valve or the like may be provided in the opening 311 of the outlet header 3.
通常は(B)が優先で作動させるが、適当に(A)と(B)とを組合わせて作動させてもよい。

According to the heat exchanger of the air conditioner of the present embodiment, (1) in the air conditioner that controls the coil outlet water temperature to be a predetermined temperature, no bypass path or bypass damper is required, and the size of the air conditioner is reduced. Can do. (2) Compared to the conventional bypass damper system, both the passing wind speed and the pipe water speed are used in the optimal range, and can be operated with high coil efficiency.

実施例1の通水主管制御機構5のピストン51の構成では、ピストン51の回動を阻止するために、ピストン51の平面部511に貫通孔55を設けて、この貫通孔55に固定シャフト56を貫通させているが、実施例2のピストン59の雌ねじ部材53は、図6に示すように、ピストン51の平面部511の中央ではなく、中央から離れた偏芯した位置に設けたものであり、他の構成は実施例1と同じである。
このように構成することで、ネジ軸54が回転してもピストン59は入口ヘッダ2の内壁24で回動を阻止され、結果として、ピストン59が管内25を上下動する。この構成では、実施例1に比較して、実施例1での貫通孔55や固定シャフト56を設ける必要がない。 In the configuration of thepiston 51 of the water flow main pipe control mechanism 5 of the first embodiment, in order to prevent the piston 51 from rotating, a through hole 55 is provided in the flat portion 511 of the piston 51, and a fixed shaft 56 is provided in the through hole 55. However, as shown in FIG. 6, the female thread member 53 of the piston 59 of the second embodiment is not provided at the center of the flat portion 511 of the piston 51 but at an eccentric position away from the center. In other respects, the configuration is the same as that of the first embodiment.
With this configuration, even if thescrew shaft 54 rotates, the piston 59 is prevented from rotating by the inner wall 24 of the inlet header 2, and as a result, the piston 59 moves up and down in the pipe 25. In this configuration, it is not necessary to provide the through hole 55 and the fixed shaft 56 in the first embodiment as compared with the first embodiment.
このように構成することで、ネジ軸54が回転してもピストン59は入口ヘッダ2の内壁24で回動を阻止され、結果として、ピストン59が管内25を上下動する。この構成では、実施例1に比較して、実施例1での貫通孔55や固定シャフト56を設ける必要がない。 In the configuration of the
With this configuration, even if the
更に、通水主管制御機構5のピストン51の回動阻止構造としては、実施例1や実施例2の他に、入口ヘッダ2の内壁25に上下方向に凸部を設け、対向するピストン51には切欠部を設けてもよく、逆に、内壁25に上下方向に凹部の切欠を設け、対向するピストン51には凸部を設けてもよい。また、入口ヘッダ2の内壁25にねじを設け、段数制御を行う仕切り板外部にもねじを有し、仕切り板をねじ部に沿ってヘッダ内を移動することが出来る構造でもよい。
Further, as a structure for preventing the rotation of the piston 51 of the water flow main pipe control mechanism 5, in addition to the first and second embodiments, a convex portion is provided on the inner wall 25 of the inlet header 2 in the vertical direction, and May be provided with a notch, or conversely, the inner wall 25 may be provided with a notch in a concave portion in the vertical direction, and the piston 51 facing may be provided with a convex portion. Alternatively, a screw may be provided on the inner wall 25 of the inlet header 2, and a screw may be provided outside the partition plate that controls the number of stages, and the partition plate can be moved in the header along the screw portion.
実施例1や実施例2のピストン51,59を用いた通水主管制御機構5と同等の構成としては、通水主管4の各入口側開口41に電磁制御弁81等の制御弁を設置する構造でもよく、これを実施例3として図7に沿って説明する。
図7の実施例3は、通水主管制御機構5のピストン51,59以外の構成は同じなので説明は省略するが、ピストン構造の代わりに各通水主管4の入口側開口41と入口ヘッダ2の接続部21及び開口211との間に電磁制御弁81等の制御弁を介在させ、これら複数の電磁制御弁81を中央制御盤(図示せず)からの指令により開閉する構成である。
この電磁制御弁81を用いた通水主管制御機構5では、通水する通水主管4、通水しない通水主管4を任意に選択することができ、バイパス箇所も任意に設定できるので空気の温度斑を解消できる。
勿論、電磁制御弁81の配置は、入口ヘッダ2の開口211と通水主管4の入口側開口41との間に電磁制御弁81等の制御弁を介在させているが、図7の構成にも、図1での出口ヘッダ3の接続部31及び開口311とに相当する構成を設け、通水主管4の出口側開口43との間に電磁制御弁81等の制御弁を介在させてもよい。 As a structure equivalent to the water flow mainpipe control mechanism 5 using the pistons 51 and 59 of the first and second embodiments, a control valve such as an electromagnetic control valve 81 is installed in each inlet side opening 41 of the water flow main pipe 4. This may be a structure, which will be described as a third embodiment with reference to FIG.
In Example 3 of FIG. 7, the configuration other than the pistons 51 and 59 of the water flow main pipe control mechanism 5 is the same and will not be described, but instead of the piston structure, the inlet side opening 41 and the inlet header 2 of each water flow main pipe 4. A control valve such as an electromagnetic control valve 81 is interposed between the connecting portion 21 and the opening 211, and the plurality of electromagnetic control valves 81 are opened and closed by a command from a central control panel (not shown).
In the water mainpipe control mechanism 5 using the electromagnetic control valve 81, the water main pipe 4 that allows water to flow and the water main pipe 4 that does not pass water can be arbitrarily selected, and the bypass location can be arbitrarily set. Can eliminate temperature spots.
Of course, theelectromagnetic control valve 81 is arranged such that a control valve such as the electromagnetic control valve 81 is interposed between the opening 211 of the inlet header 2 and the inlet side opening 41 of the water flow main pipe 4. Alternatively, a configuration corresponding to the connection portion 31 and the opening 311 of the outlet header 3 in FIG. 1 is provided, and a control valve such as an electromagnetic control valve 81 is interposed between the outlet side opening 43 of the water flow main pipe 4. Good.
図7の実施例3は、通水主管制御機構5のピストン51,59以外の構成は同じなので説明は省略するが、ピストン構造の代わりに各通水主管4の入口側開口41と入口ヘッダ2の接続部21及び開口211との間に電磁制御弁81等の制御弁を介在させ、これら複数の電磁制御弁81を中央制御盤(図示せず)からの指令により開閉する構成である。
この電磁制御弁81を用いた通水主管制御機構5では、通水する通水主管4、通水しない通水主管4を任意に選択することができ、バイパス箇所も任意に設定できるので空気の温度斑を解消できる。
勿論、電磁制御弁81の配置は、入口ヘッダ2の開口211と通水主管4の入口側開口41との間に電磁制御弁81等の制御弁を介在させているが、図7の構成にも、図1での出口ヘッダ3の接続部31及び開口311とに相当する構成を設け、通水主管4の出口側開口43との間に電磁制御弁81等の制御弁を介在させてもよい。 As a structure equivalent to the water flow main

更に、通水主管制御機構5の他の実施例4の入口ヘッダ2の図8に沿って説明する。
図8の実施例4の通水主管制御機構5は、ピストン51,59や電磁制御弁81以外の構成は同じなので説明は省略するが、これらの代わりに、円筒型のロータリシャッター82を用いて、各通水主管4の入口側開口41と入口ヘッダ2の開口211を接続を開閉させる構造である。
図8に示すように、円筒状の入口ヘッダ2の内壁に、回動軸822によって回動可能な断面円形の中空内筒823のロータリシャッター82を配置し、この筒型のロータリシャッター82は図8(点線部)に示すように、回転方向に異なる長さの長孔821が、接続部21の開口211に接するようにスライドしながら回転する。
したがって、ロータリシャッター82の回動軸822の回動度合いを制御すれば、長孔821と開口211が合致した場合は開通して通水主管4は通水し、合致しない場合には通水主管4は通水しないので、実施例1乃至3と同等の作用・効果が得られる。
また、長孔821を任意に設計することにより、通水主管4のバイパス箇所も任意に設定でできるので空気の温度斑を解消できる。
勿論、ロータリシャッター82の配置は、出口ヘッダ3の側に配置してもよい。 Furthermore, it demonstrates along FIG. 8 of theinlet header 2 of the other Example 4 of the water flow main pipe control mechanism 5. FIG.
The configuration of the water flow mainpipe control mechanism 5 of the fourth embodiment shown in FIG. 8 is the same as that of the pistons 51 and 59 and the electromagnetic control valve 81, and therefore the description thereof is omitted. Instead, a cylindrical rotary shutter 82 is used. In this structure, the connection between the inlet side opening 41 of each water flow main pipe 4 and the opening 211 of the inlet header 2 is opened and closed.
As shown in FIG. 8, arotary shutter 82 of a hollow inner cylinder 823 having a circular cross section that can be rotated by a rotation shaft 822 is disposed on the inner wall of the cylindrical inlet header 2, and this cylindrical rotary shutter 82 is illustrated in FIG. As shown by 8 (dotted line portion), the long holes 821 having different lengths in the rotation direction rotate while sliding so as to contact the opening 211 of the connection portion 21.
Therefore, if the degree of rotation of therotary shaft 822 of the rotary shutter 82 is controlled, when the long hole 821 and the opening 211 match, it opens and the water passage main pipe 4 passes, and when it does not match, the water passage main pipe. Since No. 4 does not pass water, the same operation and effect as in Examples 1 to 3 can be obtained.
Moreover, since the bypass location of the water flowmain pipe 4 can be arbitrarily set by arbitrarily designing the long hole 821, air temperature spots can be eliminated.
Of course, therotary shutter 82 may be arranged on the outlet header 3 side.
図8の実施例4の通水主管制御機構5は、ピストン51,59や電磁制御弁81以外の構成は同じなので説明は省略するが、これらの代わりに、円筒型のロータリシャッター82を用いて、各通水主管4の入口側開口41と入口ヘッダ2の開口211を接続を開閉させる構造である。
図8に示すように、円筒状の入口ヘッダ2の内壁に、回動軸822によって回動可能な断面円形の中空内筒823のロータリシャッター82を配置し、この筒型のロータリシャッター82は図8(点線部)に示すように、回転方向に異なる長さの長孔821が、接続部21の開口211に接するようにスライドしながら回転する。
したがって、ロータリシャッター82の回動軸822の回動度合いを制御すれば、長孔821と開口211が合致した場合は開通して通水主管4は通水し、合致しない場合には通水主管4は通水しないので、実施例1乃至3と同等の作用・効果が得られる。
また、長孔821を任意に設計することにより、通水主管4のバイパス箇所も任意に設定でできるので空気の温度斑を解消できる。

上記実施例1乃至実施例3の熱交換器1の他の使用状態を空調機6を図9で説明する。
実施例1の図6の構成と異なるのは、出口ヘッダ3から排出側配管26には熱交換器(コイル)の出口水温センサー(T4)16が配置され、この出口水温センサー(T4)16の温度を検出し、出口水温センサー(T4)16の水温が所定の温度になるように、変速機構571を介してモータ57の回転量を制御する。
このような構成であるので、入口ヘッダ2の通水段数制御機構5を制御することで、熱媒が遮断されている通水主管4は熱交換器1の通風してバイパス機能を有するが、コイル出口水温(T4)16が所定の温度になるよう、コイルヘッダ部の通水段数制御機構(通水段数)を制御する。
ただし、この構成では、コイル出口空気温度は、段数制御のパス数に応じたバイパス風量とのミキシングにとなり、成り行きの温度で、所定の吹き出し温度とはならないので、室内負荷制御は、VAV制御を別系統で行うことになる。
この実施例1のコイル出口水温を所定の温度になるよう制御して使用状態しない場合には、通水段数制御機構5自体は、電動二方弁の代わりに水量制御機能を有することができる。 The other use state of theheat exchanger 1 of the said Example 1 thru | or Example 3 demonstrates the air conditioner 6 with FIG.
6 differs from the configuration of FIG. 6 of the first embodiment in that an outlet water temperature sensor (T4) 16 of a heat exchanger (coil) is arranged from theoutlet header 3 to the discharge side pipe 26, and the outlet water temperature sensor (T4) 16 The temperature is detected, and the rotation amount of the motor 57 is controlled via the speed change mechanism 571 so that the water temperature of the outlet water temperature sensor (T4) 16 becomes a predetermined temperature.
Since it is such a configuration, by controlling the water flow stagenumber control mechanism 5 of the inlet header 2, the water flow main pipe 4 in which the heat medium is blocked has a bypass function through the ventilation of the heat exchanger 1. The water flow stage number control mechanism (water flow stage number) of the coil header part is controlled so that the coil outlet water temperature (T4) 16 becomes a predetermined temperature.
However, in this configuration, the coil outlet air temperature is mixed with the bypass air volume corresponding to the number of passes in the stage number control, and does not become the predetermined blowing temperature at the expected temperature. It will be done in a separate system.
When the coil outlet water temperature of the first embodiment is controlled to be a predetermined temperature and is not in use, the water flow stagenumber control mechanism 5 itself can have a water amount control function instead of the electric two-way valve.
実施例1の図6の構成と異なるのは、出口ヘッダ3から排出側配管26には熱交換器(コイル)の出口水温センサー(T4)16が配置され、この出口水温センサー(T4)16の温度を検出し、出口水温センサー(T4)16の水温が所定の温度になるように、変速機構571を介してモータ57の回転量を制御する。
このような構成であるので、入口ヘッダ2の通水段数制御機構5を制御することで、熱媒が遮断されている通水主管4は熱交換器1の通風してバイパス機能を有するが、コイル出口水温(T4)16が所定の温度になるよう、コイルヘッダ部の通水段数制御機構(通水段数)を制御する。
ただし、この構成では、コイル出口空気温度は、段数制御のパス数に応じたバイパス風量とのミキシングにとなり、成り行きの温度で、所定の吹き出し温度とはならないので、室内負荷制御は、VAV制御を別系統で行うことになる。
