Description
本発明は、放射線使用施設や医療施設などの室内換気基準が高く、空調エネルギーが大きく、排気に対して熱交換器を用いて熱回収している回転型全熱交換器に関するものである。 The present invention relates to a rotary total heat exchanger that has high indoor ventilation standards, such as radiation-use facilities and medical facilities, has large air-conditioning energy, and uses a heat exchanger to recover heat with respect to exhaust.
放射線使用施設では施設内環境保全のため、室内換気回数が１０〜４０回／時に及び空調エネルギーが大きいので、省エネルギー対策している設備では排気熱は熱交換器を用いて熱回収しているのが現状である。リターン空気が入ると汚染空気の濃度が濃くなることから、全量フレッシュ空気が原則である。このような空調設備においては、一般的に、熱交換器も給気と排気が完全分離された静止型熱交換器が採用されている。 In the facility using radiation, the indoor ventilation frequency is 10-40 times / hour and the air-conditioning energy is large in order to preserve the environment in the facility, so the exhaust heat is recovered by using a heat exchanger in the energy saving equipment. Is the current situation. Since the concentration of polluted air increases when return air enters, the whole amount of fresh air is the principle. In such an air conditioning facility, a static heat exchanger in which supply air and exhaust gas are completely separated is generally employed as the heat exchanger.
一般的に、排気と給気の異なる２種類の気流を全熱交換する熱交換素子群を収容するローターと、該熱交換素子群を収容するローターの両側に形成された気流の排気用ダクトおよび給気用ダクトとから構成される回転型全熱交換器が用いる方が、熱回収効率が静止型に比べて格段に向上する。 In general, a rotor that houses a heat exchange element group that performs total heat exchange between two types of airflows that are different in exhaust and supply air, and an airflow exhaust duct formed on both sides of the rotor that houses the heat exchange element group, and The heat recovery efficiency is significantly improved when the rotary total heat exchanger composed of the air supply duct is used as compared with the stationary type.
しかしながら、上記回転型全熱交換器の場合、熱交換素子群を収容するローターが回転しているため、排気用ダクトから給気用ダクトへ空気（リターン空気）が入る可能性がある。そのため、放射線使用施設のような施設内環境保全の基準が高い施設には、回転型全熱交換器を採用することができなかった。
なお、熱交換素子群を収容するローターは、必ず各室との間に隙間があり、色々な方法でシールされている。しかしながら、一般の全熱交換器は空気の漏れ量が５％前後（多いものでは１０％）も存在する。また、熱交換素子群を収容するローターの汎用製品では、空気の漏れ量が２〜５％程度存在するといった状況である。
However, in the case of the rotary total heat exchanger, since the rotor accommodating the heat exchange element group is rotating, there is a possibility that air (return air) enters the air supply duct from the exhaust duct. For this reason, a rotary total heat exchanger could not be employed in a facility having a high standard of environmental conservation in a facility such as a radiation use facility.
In addition, the rotor which accommodates a heat exchange element group always has a clearance gap between each chamber, and is sealed by various methods. However, a general total heat exchanger has an air leakage amount of about 5% (10% at most). Moreover, in the general-purpose product of the rotor that accommodates the heat exchange element group, the amount of air leakage is about 2 to 5%.
本発明は、かかるリターン空気が入るリスクを最小限にする回転型全熱交換器を提供することを目的とする。 It is an object of the present invention to provide a rotary total heat exchanger that minimizes the risk of such return air entering.
上記目的を達成するため、本発明の回転型全熱交換器は、給気と排気の異なる２種類の気流を全熱交換する熱交換素子群を収容するローターと、該ローターの前後に設けられた中央仕切板によって形成された気流の給気用ダクトおよび排気用ダクトと、給気用ダクトと排気用ダクトにそれぞれ気流を起こす給気ファンと排気ファンとから成る回転型全熱交換器において、以下に示される特徴（構成）を備える。
１）先ず、給気ファンの配置は、押し込み配置、すなわち、回転型全熱交換器内に気流を押し込む配置とする。そして、排気ファンの配置は、引き込み配置、すなわち、回転型全熱交換器内から気流を引き込む配置とする。
従前の回転型全熱交換器の場合、給気ファンは、抵抗のある物はファンのサクション側に付けて押込み圧を高くするのが効率的であることから、給気ファンはハニカム型の熱交換素子群の出口側に設けるのが一般的である。本発明は、給気ファンをハニカム型熱交換素子群の入り口側に取付けることでハニカム型熱交換素子群の入り側で室圧を陽圧にし、排気ファンをハニカム型熱交換素子群の出口側に取付けることでハニカム型の熱交換素子群の室圧を陰圧にしたのが特徴である。
２）排気用ダクト内圧が給気用ダクト内圧より常時低くなるように、給気ファン及び／又は排気ファンの回転数を制御する。具体的な制御としては、各室内の給排気はＶＡＶ（Variable Air Volume)で流量が制御され、若しくはＯＮ−ＯＦＦ制御されているため、給排気ファン共に回転数を制御して風量を制御する。また、仮に差圧が逆転した状態になれば警報を発信し、状態改善できなかった場合は設備の停止を行うように制御設計を行うのが好ましい。
３）給気用ダクト内における熱交換素子に対する給気の流出側でローターの回転方向の上流側と、排気用ダクト内における熱交換素子に対する排気の流入側でローターの回転方向の下流側とに、略扇状の遮蔽板が設ける。
In order to achieve the above object, a rotary total heat exchanger according to the present invention is provided with a rotor that houses a heat exchange element group that performs total heat exchange between two types of airflows that are different from supply air and exhaust, and before and after the rotor. A rotary total heat exchanger comprising an air supply duct and an exhaust duct formed by a central partition plate, and an air supply fan and an exhaust fan that generate an airflow in the air supply duct and the exhaust duct, respectively. The following features (configuration) are provided.
1) First, the arrangement of the air supply fan is a push-in arrangement, that is, an arrangement in which the airflow is pushed into the rotary total heat exchanger. And the arrangement | positioning of an exhaust fan shall be drawing-in arrangement | positioning, ie, the arrangement | positioning which draws in air current from the inside of a rotary total heat exchanger.
In the case of the conventional rotary total heat exchanger, it is efficient to increase the indentation pressure by attaching a resistance object to the suction side of the fan. Generally, it is provided on the exit side of the exchange element group. The present invention attaches an air supply fan to the inlet side of the honeycomb type heat exchange element group to make the chamber pressure positive at the entrance side of the honeycomb type heat exchange element group, and the exhaust fan to the outlet side of the honeycomb type heat exchange element group It is characterized in that the chamber pressure of the honeycomb type heat exchange element group is set to a negative pressure by being attached to.
2) The rotational speed of the supply fan and / or the exhaust fan is controlled so that the exhaust duct internal pressure is always lower than the supply duct internal pressure. As specific control, since the flow rate of air supply / exhaust in each room is controlled by VAV (Variable Air Volume) or ON-OFF control, the air volume is controlled by controlling the rotational speed of both the air supply / exhaust fans. Further, it is preferable to design the control so that an alarm is issued if the differential pressure is reversed, and the equipment is stopped if the state cannot be improved.
3) On the upstream side in the rotation direction of the rotor on the outflow side of the supply air to the heat exchange element in the air supply duct, and on the downstream side in the rotation direction of the rotor on the inflow side of exhaust to the heat exchange element in the exhaust duct. A substantially fan-shaped shielding plate is provided.
上記１）〜３）の特徴を備えることにより、回転型全熱交換器の内圧は、排気用ダクト内圧が給気用ダクト内圧より常時低くなるように制御でき、それにより排気用ダクトを通る空気が給気用ダクトに戻るといったリターン空気を最小限に抑えることが可能となる。 By providing the above features 1) to 3), the internal pressure of the rotary total heat exchanger can be controlled so that the exhaust duct internal pressure is always lower than the supply duct internal pressure, and thereby the air passing through the exhaust duct It is possible to minimize the return air that returns to the air supply duct.
また、上記４）の構成により、排気用ダクトを通る空気（排気）が、ローターの内部の熱交換素子内を通過する際に、ローターが回転することにより配管自体が中央仕切板で仕切られている排気用ダクト側から給気用ダクト側に移動した場合を想定して、希釈の効果を利用してリターン空気が入るリスクを最小限に抑えるものである。
すなわち、ローターの回転により排気が流れている熱交換素子内が給気用ダクトに移動した直後は、給気用ダクト内における熱交換素子に対する給気の流出側でローターの回転方向の上流側に設けられた略扇状の遮蔽板の作用によって、給気ファンから押し出された気流の影響を受け難くなるので、熱交換素子の配管内に残留している空気（排気）が徐々に遮蔽板の反対側から給気用ダクトに流出することになる。これにより、仮に排気が汚染されている場合でも、希釈の効果により汚染濃度は無視できるレベルとなるのである。
In addition, with the configuration of 4), when the air (exhaust gas) passing through the exhaust duct passes through the heat exchange element inside the rotor, the rotor rotates so that the pipe itself is partitioned by the central partition plate. Assuming the case of moving from the exhaust duct side to the air supply duct side, the risk of return air entering is minimized by utilizing the effect of dilution.
That is, immediately after the inside of the heat exchange element in which the exhaust gas is flowing due to the rotation of the rotor moves to the supply duct, the supply air outflow side with respect to the heat exchange element in the supply duct is upstream of the rotation direction of the rotor. The effect of the substantially fan-shaped shielding plate provided makes it less susceptible to the airflow pushed out of the air supply fan, so the air (exhaust gas) remaining in the heat exchange element pipe is gradually opposite the shielding plate. It will flow out to the air supply duct from the side. Thereby, even if the exhaust gas is contaminated, the contamination concentration is negligible due to the effect of dilution.
また、排気用ダクト内における熱交換素子に対する排気の流入側でローターの回転方向の下流側に設けられた略扇状の遮蔽板の作用によって、熱交換素子の配管内に残留している空気（排気）が徐々に遮蔽板の反対側から排気用ダクトに流出することになる。
すなわち、熱交換素子の配管内に残留している空気（排気）は、排気ファンから引き込まれるため、希釈されていくのである。仮に排気が汚染されている場合でも、希釈の効果により汚染濃度は無視できるレベルとなり、ローターの回転によって給気用ダクト側に移動していくことになる。
In addition, air (exhaust gas) remaining in the pipe of the heat exchange element by the action of a substantially fan-shaped shielding plate provided on the inflow side of the exhaust gas with respect to the heat exchange element in the exhaust duct and downstream in the rotational direction of the rotor. ) Gradually flows out from the opposite side of the shielding plate to the exhaust duct.
That is, the air (exhaust gas) remaining in the pipe of the heat exchange element is drawn from the exhaust fan and is diluted. Even if the exhaust gas is contaminated, the concentration of contamination becomes negligible due to the effect of dilution, and the exhaust gas moves toward the air supply duct by the rotation of the rotor.
ここで、上記の遮蔽板は、具体的には中心角５〜１０度の扇形状を成すものが好ましい。この遮蔽板の中心角は、熱交換素子群を収容するローターの回転軸方向の長さや、ローターの回転速度との兼ね合いで中心角５〜１０度の範囲で設計がなされる。遮蔽板の中心角が５度よりも小さくなれば、熱交換素子の配管に残留している排気が遮蔽板の反対側から徐々に給気用ダクトに流出するための余裕度が低くなり、希釈の効果を利用してリターン空気が入るリスクを最小限に抑えることが困難となる。また、遮蔽板の中心角が１０度よりも大きくなれば、ダクト内の気流の通過面積が小さくなり交換器の熱交換効率が低下することになる。
具体的には、給気側５度、排気側５度、遮蔽板を設けるのが好ましい。
Here, specifically, the shielding plate preferably has a fan shape with a central angle of 5 to 10 degrees. The central angle of the shielding plate is designed in the range of the central angle of 5 to 10 degrees in consideration of the length in the rotation axis direction of the rotor accommodating the heat exchange element group and the rotational speed of the rotor. If the central angle of the shielding plate is smaller than 5 degrees, the margin for the exhaust gas remaining in the heat exchange element piping to gradually flow out from the opposite side of the shielding plate to the air supply duct is reduced. It is difficult to minimize the risk that return air will enter by using the effect of. Further, if the central angle of the shielding plate is larger than 10 degrees, the passage area of the airflow in the duct is reduced, and the heat exchange efficiency of the exchanger is lowered.
Specifically, it is preferable to provide a shielding plate with 5 degrees on the air supply side, 5 degrees on the exhaust side.
また、本発明の回転型全熱交換器は、上記１）〜４）の特徴（構成）に加え、排気用ダクト内圧と給気用ダクト内圧の差圧を検知する差圧検知手段と、給気ファンの回転軸に連結されるモータ回転を制御するモータ制御手段を更に備え、給気ファンの回転数を制御することが好ましい。
差圧検知手段は、例えば、給気のハニカム型熱交換素子群の入り口と排気のハニカム型熱交換素子群の出口間の部屋の差圧、及び、給気のハニカム型熱交換素子群の出口と排気のハニカム型熱交換素子群の入り口の部屋の差圧を監視することにより行う。その何れかの差圧で排気側が高い場合は、給気側が正圧になるまで給気ファンの回転数を上げる。但し、給気側は正圧、排気側は負圧のため、給気側が排気側より低い圧になる事態は生じず、この場合は、給気ファンが回転しなかった場合となるため故障警報が鳴り、装置は全停止することになる。
The rotary total heat exchanger according to the present invention includes, in addition to the features (configurations) 1) to 4), a differential pressure detecting means for detecting a differential pressure between the exhaust duct internal pressure and the supply duct internal pressure, It is preferable to further include motor control means for controlling the rotation of the motor connected to the rotation shaft of the air fan, and to control the rotation speed of the air supply fan.
The differential pressure detection means includes, for example, the differential pressure in the room between the inlet of the honeycomb-type heat exchange element group for supply air and the outlet of the honeycomb-type heat exchange element group for exhaust gas, and the outlet of the honeycomb-type heat exchange element group for supply air And monitoring the differential pressure in the entrance room of the honeycomb-type heat exchange element group for exhaust. When the exhaust side is high at any of the differential pressures, the rotation speed of the supply fan is increased until the supply side becomes positive pressure. However, because the supply side is positive pressure and the exhaust side is negative pressure, there is no situation where the supply side is lower than the exhaust side. In this case, the supply fan does not rotate, so there is a failure warning. Will sound and the device will stop.
特に、上記の差圧検知手段において、排気用ダクト内圧が給気用ダクト内圧より大きい場合に、警報を発信する警報告知手段を更に設けることが好ましい。
排気用ダクト内圧が給気用ダクト内圧より大きい場合には、排気の漏れを補償できない可能性が高く、かかる場合に警報を発信することとしたものである。
さらに、状態が改善されない場合は設備停止が好ましい。
In particular, in the differential pressure detection means described above, it is preferable to further provide a warning reporting means for issuing an alarm when the exhaust duct internal pressure is greater than the supply duct internal pressure.
When the exhaust duct internal pressure is larger than the air supply duct internal pressure, there is a high possibility that exhaust leakage cannot be compensated for, and an alarm is issued in such a case.
Furthermore, when the state is not improved, the equipment is preferably stopped.
本発明の回転型全熱交換器によれば、リターン空気が入るリスクを最小限にし、静止型に比べて熱回収効率を大幅に向上できるといった効果がある。 According to the rotary total heat exchanger of the present invention, there is an effect that the risk that return air enters can be minimized and the heat recovery efficiency can be greatly improved as compared with the stationary type.
以下、本発明の実施形態について、図面を参照しながら詳細に説明していく。ただし、本発明の範囲は、図示例に限定されるものではない。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples.
図１において、回転型全熱交換器１は、ハニカム型の熱交換素子群９を収納するローター２と、ローター２の回転軸上にある中央仕切板３によって仕切られている給気用ダクト４及び排気用ダクト５と、それぞれのダクトに設けられた給気ファン７と排気ファン８とから構成されている。また、給気用ファン７と排気用ファン８の配置は、それぞれ押し込み配置と引き込み配置となっている。そして、排気用ダクト５の内圧（Ｐｅ）が給気用ダクト４の内圧（Ｐｓ）より常時低くなるように、給気ファン７若しくは排気ファン８の回転数が制御されている。 In FIG. 1, a rotary total heat exchanger 1 includes a rotor 2 that houses a honeycomb-type heat exchange element group 9, and an air supply duct 4 that is partitioned by a central partition plate 3 on the rotation axis of the rotor 2. And an exhaust duct 5 and an air supply fan 7 and an exhaust fan 8 provided in each duct. The arrangement of the air supply fan 7 and the exhaust fan 8 is a push-in arrangement and a pull-in arrangement, respectively. The rotational speed of the air supply fan 7 or the exhaust fan 8 is controlled so that the internal pressure (Pe) of the exhaust duct 5 is always lower than the internal pressure (Ps) of the air supply duct 4.
図２に示すように、ローター２は、クラフト紙（又はアルミ）製などの積層ハニカム構造の熱交換素子群９を有しており、ローター２の回転軸は駆動モーター（図示せず）に接続されている。ローター２は駆動モーター（図示せず）によって１分間に５〜１０回転している。
排気用ダクト５を通る空気（排気）が、ローター２の内部の熱交換素子郡９の配管を通過する際に、ローター２が回転することにより通気孔自体が中央仕切板３で仕切られている排気用ダクト５側から給気用ダクト４側に移動する場合を考える。
ローター２の回転により排気が流れている熱交換素子群９の配管が給気用ダクト４側に移動した直後は、給気用ダクト４内における熱交換素子群９に対する給気の流出側でローターの回転方向の上流側に設けられた中心角５度の扇状の遮蔽板８の作用によって、給気ファン６から押し出された気流の影響を受け難くなる。これにより、熱交換素子群９の配管内に残留している空気（排気）が徐々に遮蔽板８の反対側から給気用ダクト４に流出することになる。
従って、仮に排気が汚染されている場合でも、希釈の効果により汚染濃度は無視できるレベルとなるのである。
As shown in FIG. 2, the rotor 2 has a heat exchange element group 9 having a laminated honeycomb structure such as craft paper (or aluminum), and the rotating shaft of the rotor 2 is connected to a drive motor (not shown). Has been. The rotor 2 is rotated 5 to 10 times per minute by a drive motor (not shown).
When the air (exhaust gas) passing through the exhaust duct 5 passes through the piping of the heat exchange element group 9 inside the rotor 2, the air holes themselves are partitioned by the central partition plate 3 by the rotation of the rotor 2. Consider the case of moving from the exhaust duct 5 side to the air supply duct 4 side.
Immediately after the piping of the heat exchange element group 9 through which the exhaust gas is flowing due to the rotation of the rotor 2 moves to the air supply duct 4 side, the rotor on the outflow side of the air supply to the heat exchange element group 9 in the air supply duct 4 Due to the action of the fan-shaped shielding plate 8 having a central angle of 5 degrees provided on the upstream side in the rotation direction, it is difficult to be influenced by the airflow pushed out from the air supply fan 6. As a result, air (exhaust gas) remaining in the piping of the heat exchange element group 9 gradually flows out from the opposite side of the shielding plate 8 to the air supply duct 4.
Therefore, even if the exhaust gas is contaminated, the contamination concentration is negligible due to the effect of dilution.
また、排気用ダクト５内における熱交換素子群９に対する排気の流入側でローター２の回転方向の下流側に設けられた中心角５度の扇状の遮蔽板８の作用によって、熱交換素子群９の配管内に残留している空気（排気）が徐々に遮蔽板８の反対側から排気用ダクト５に流出することになる。
すなわち、熱交換素子群９の配管内に残留している空気（排気）は、排気ファン７から引き込まれるため、希釈されていくことになる。
従って、仮に排気が汚染されている場合でも、希釈の効果により汚染濃度は無視できるレベルとなり、ローター２の回転によって給気用ダクト４側に移動していくことになる。
Further, the heat exchange element group 9 is obtained by the action of the fan-shaped shielding plate 8 having a central angle of 5 degrees provided on the exhaust inflow side with respect to the heat exchange element group 9 in the exhaust duct 5 and on the downstream side in the rotation direction of the rotor 2. The air (exhaust gas) remaining in the pipe gradually flows out from the opposite side of the shielding plate 8 to the exhaust duct 5.
That is, the air (exhaust gas) remaining in the piping of the heat exchange element group 9 is drawn from the exhaust fan 7 and is diluted.
Therefore, even if the exhaust gas is contaminated, the contamination concentration becomes a negligible level due to the effect of dilution, and the exhaust gas moves toward the supply air duct 4 side by the rotation of the rotor 2.
図３に回転型全熱交換器のローター断面の扇状の遮蔽板を示す。ここで、遮蔽板は中心角１０度の扇形状をなしている。遮蔽板の中心角が１０度以内とすることで、ダクト内の気流の通過面積を十分に確保して、交換器の熱交換効率が低下することを防いでいる。
遮蔽板は、中央仕切板３（図示せず）で仕切られた給気側と排気側にそれぞれに中心角５度の扇状の遮蔽板を設けて、全体として中心角１０度の扇形状の遮蔽板を形成している。
FIG. 3 shows a fan-shaped shielding plate having a rotor cross section of the rotary total heat exchanger. Here, the shielding plate has a fan shape with a central angle of 10 degrees. By setting the central angle of the shielding plate to be within 10 degrees, it is possible to secure a sufficient area for the air flow in the duct to prevent the heat exchange efficiency of the exchanger from being lowered.
The shield plate is provided with fan-shaped shield plates with a central angle of 5 degrees on the air supply side and the exhaust side partitioned by a central partition plate 3 (not shown), and as a whole, a fan-shaped shield with a central angle of 10 degrees. A plate is formed.
本発明の回転型全熱交換器は、放射線使用施設や医療施設などの室内換気基準が高く、空調エネルギーが大きく、排気に対して熱交換器を用いて熱回収している設備に利用できる。 The rotary total heat exchanger of the present invention has high indoor ventilation standards such as radiation use facilities and medical facilities, has large air conditioning energy, and can be used for facilities that recover heat using a heat exchanger for exhaust.
