Description

この発明は、全熱交換素子および全熱交換装置に関するものである。 The present invention relates to a total heat exchange element and a total heat exchange device.

室内の空調の冷暖房効率の損失を抑えた換気方法として、給気流と排気流との間で熱交換を行わせる換気方法がある。熱交換の効率を向上させるためには、給気流と排気流との間で温度（顕熱）とともに湿度（潜熱）の交換も同時に行う全熱交換が有効である。 As a ventilation method that suppresses the loss of cooling and heating efficiency of the indoor air conditioning, there is a ventilation method in which heat exchange is performed between the supply air flow and the exhaust flow. In order to improve the efficiency of heat exchange, it is effective to perform total heat exchange that simultaneously exchanges humidity (latent heat) as well as temperature (sensible heat) between the supply airflow and the exhaust airflow.

全熱交換を行う全熱交換素子では、給気流路と排気流路とが、仕切板を挟んで互いに独立した流路として形成される。給気流路を流れる給気流と、排気流路を流れる排気流との間で全熱交換が行われるため、全熱交換素子を備える全熱交換装置で室内の空気を換気することによって、室内の空調の冷暖房時に使用したエネルギ、また除加湿で使用したエネルギの損失を抑えることができる。 In a total heat exchange element that performs total heat exchange, an air supply channel and an exhaust channel are formed as channels independent of each other with a partition plate interposed therebetween. Since total heat exchange is performed between the supply airflow flowing through the supply air flow path and the exhaust flow flowing through the exhaust flow path, the indoor air is ventilated by a total heat exchange device including a total heat exchange element. Loss of energy used at the time of air conditioning cooling and energy used for dehumidification / humidification can be suppressed.

たとえば、特許文献１には、仕切板の表裏両面にリブを成型し、それぞれの面のリブが直交する構造を備える全熱交換素子が開示されている。また、特許文献２には、枠リブよりも短い間隔リブを仕切板の裏表両面に備える全熱交換素子が開示されている。 For example, Patent Document 1 discloses a total heat exchange element having a structure in which ribs are formed on both front and back surfaces of a partition plate, and the ribs on each surface are orthogonal to each other. Further, Patent Document 2 discloses a total heat exchange element provided with spacing ribs shorter than the frame ribs on both the front and back surfaces of the partition plate.

しかしながら、特許文献１に開示された技術では、間隔保持リブが、間隔保持リブの延在方向の仕切板の寸法と同じ長さで連続して繋がっているため、仕切板の伝熱面積を大きく減らし、全熱交換素子の性能が低くなるという問題点があった。 However, in the technique disclosed in Patent Document 1, since the spacing rib is continuously connected with the same length as the dimension of the partition plate in the extending direction of the spacing rib, the heat transfer area of the partition plate is increased. There is a problem that the performance of the total heat exchange element is reduced.

特許文献２に開示された技術では、リブを成型した後に仕切板を貼付ける工程が必要であるため、製造工程が多くなり、生産性が低いという問題点があった。また、仕切板貼付け工程において、仕切板と成型樹脂の接着を行うため、接着時に仕切板が撓み作業性が悪く、さらに接着部に隙間が生じ気流が漏れてしまうという問題点もあった。 In the technique disclosed in Patent Document 2, a process of attaching a partition plate after molding a rib is necessary, so that the number of manufacturing processes increases and productivity is low. In addition, since the partition plate and the molding resin are bonded in the partition plate attaching step, the partition plate is bent at the time of bonding, and workability is poor, and further, there is a problem that a gap is formed in the bonded portion and airflow leaks.

At this time, the back surface 13 of another unit element 10 adjacent in the Z direction is opposed to the front surface 12 of a certain unit element 10, and the other unit element 10 is rotated 90 degrees in the XY plane with respect to the unit element 10 with the other unit element 10. The unit elements 10 are stacked so that the total heat exchange element 1 is formed so that the arrangement described above is achieved.

このようにＺ方向に積層させると、ある単位素子１０の表面１２の流路Ｐ１の方向と、他の単位素子１０の裏面１３の流路Ｐ２の方向とが一致し、１つの流路Ｐを形成する。そして、Ｚ方向に積層させた単位素子１０間の流路Ｐに形成されるリブは図５に示されるように配置される。この図５では、便宜上、表面１２に形成されるリブ２１〜２３と、裏面１３に形成されるリブ３１〜３３と、が区別可能なように、裏面１３に形成されるリブ３１〜３３にハッチングを付している。 When stacked in the Z direction in this way, the direction of the flow path P1 on the front surface 12 of a certain unit element 10 matches the direction of the flow path P2 on the back surface 13 of the other unit element 10, and one flow path P is formed. Form. And the rib formed in the flow path P between the unit elements 10 laminated | stacked on the Z direction is arrange | positioned as FIG. 5 shows. In FIG. 5, for convenience, the ribs 31 to 33 formed on the back surface 13 are hatched so that the ribs 21 to 23 formed on the front surface 12 and the ribs 31 to 33 formed on the back surface 13 can be distinguished. Is attached.

この図５に示されるように、ある単位素子１０の表面１２に形成される流路Ｐ１と、Ｚ方向に隣接する他の単位素子１０の裏面１３に形成される流路Ｐ２と、が重なることによって形成される流路Ｐでは、ある単位素子１０のＹ方向に延在する封止リブ２１と、他の単位素子１０のＸ方向に延在する接続封止リブ３１とが、延在方向が一致するように配置される。ある単位素子１０の表面１２を基準にすると（以下も同様）、ある単位素子１０のＸ方向の両端に、封止リブ２１と接続封止リブ３１は配置される。このとき、ある単位素子１０の表面１２の２列の封止リブ２１と他の単位素子１０の裏面１３の２列の接続封止リブ３１とは、それぞれの凹部に一方のリブが嵌め込まれた構造となり、Ｚ方向に隣接する単位素子１０間が固定される。これによって、４本のＹ方向に延在するリブが一塊になって、封止リブとして仕切板１１のＸ方向の端部を支持することになる。 As shown in FIG. 5, the flow path P1 formed on the front surface 12 of a certain unit element 10 and the flow path P2 formed on the back surface 13 of another unit element 10 adjacent in the Z direction overlap. In the flow path P formed by the sealing element 21, the sealing rib 21 extending in the Y direction of a certain unit element 10 and the connecting sealing rib 31 extending in the X direction of another unit element 10 have an extending direction. Arranged to match. When the surface 12 of a certain unit element 10 is used as a reference (and so on), the sealing ribs 21 and the connection sealing ribs 31 are disposed at both ends of the certain unit element 10 in the X direction. At this time, two ribs of the sealing ribs 21 on the front surface 12 of one unit element 10 and the two rows of connection sealing ribs 31 on the back surface 13 of the other unit element 10 have one rib fitted in each recess. The structure is fixed, and the unit elements 10 adjacent in the Z direction are fixed. As a result, the four ribs extending in the Y direction form a lump and support the end portion in the X direction of the partition plate 11 as a sealing rib.

また、Ｚ方向に隣接する２つの単位素子１０によって形成される流路Ｐでは、保持リブ２２と接続保持リブ３２が、仕切板１１のＸ方向の中央にＹ方向に延在するように配置される。具体的には、ある単位素子１０の表面１２の中央部に間隙２２ｃを有するように配置される保持リブ２２と、他の単位素子１０の裏面１３の接続保持リブ３２とが、一体化され、１本のＹ方向に延在する保持リブが形成される。このとき、接続保持リブ３２のＹ方向中央部付近の接続部３２ｃが、保持リブ２２の間隙２２ｃに嵌め込まれる。これによって、２本のＹ方向に延在するリブが一塊となって、保持リブとして仕切板１１のＸ方向の中央部を支持することになる。 Further, in the flow path P formed by two unit elements 10 adjacent in the Z direction, the holding rib 22 and the connection holding rib 32 are arranged to extend in the Y direction at the center of the partition plate 11 in the X direction. The Specifically, the holding rib 22 disposed so as to have a gap 22c in the center of the surface 12 of a certain unit element 10 and the connection holding rib 32 on the back surface 13 of the other unit element 10 are integrated, One holding rib extending in the Y direction is formed. At this time, the connection portion 32 c near the central portion in the Y direction of the connection holding rib 32 is fitted into the gap 22 c of the holding rib 22. As a result, the two ribs extending in the Y direction form a lump and support the central portion in the X direction of the partition plate 11 as a holding rib.

このように、接続保持リブ３２と保持リブ２２とが嵌め合わされる構造としているため、たとえば積層する際に、ある単位素子１０に対して、他の単位素子１０をＸＹ面内で９０度回転しなかった場合には、接続保持リブ３２の一部と保持リブ２２の一部とが干渉してしまうことになるので、積層方法を間違えていることを認識しやすくすることができる。また、積層時にはある単位素子１０の表面１２中央の間隙２２ｃと他の単位素子１０の裏面１３中央の接続部３２ｃとの嵌合によって位置決めをすることで、単位素子１０間の積層ズレを防止することができる。 Since the connection holding rib 32 and the holding rib 22 are thus fitted together, for example, when stacking, another unit element 10 is rotated 90 degrees in the XY plane with respect to a certain unit element 10. If not, a part of the connection holding rib 32 and a part of the holding rib 22 interfere with each other, so that it is easy to recognize that the stacking method is wrong. Further, during stacking, positioning is performed by fitting the gap 22c at the center of the front surface 12 of a certain unit element 10 and the connection portion 32c at the center of the back surface 13 of another unit element 10, thereby preventing stacking misalignment between the unit elements 10. be able to.

これらの一体化された封止リブと一体化された保持リブとの間に、流路Ｐが形成され、そこに、ある単位素子１０の表面１２の飛びリブ２３と他の単位素子１０の裏面１３の接続飛びリブ３３とが、互いに同列内の同軸上で隙間となった部分を補填し、流路Ｐ内の飛びリブ２３と接続飛びリブ３３は規則正しく互い違いの配置となる。これによって、一体化された封止リブと一体化された保持リブとの間に、Ｙ方向に所定の間隔で配置される一列の飛びリブが、３列形成されることになる。このように飛びリブ２３と接続飛びリブ３３が流れ方向に同一軸上に揃って配置されるため、また、飛びリブ２３と接続飛びリブ３３で形成された風路は、リブが細切れになっているため、リブによる気流の摩擦抵抗を小さくでき、各風路を低圧力損失となる形状に形成することができる。さらに、この場合には、ある単位素子１０の飛びリブ２３は、流路Ｐ内に構成される飛びリブ２３と接続飛びリブ３３の合計の約半数を占めることになる。 A flow path P is formed between the integrated sealing rib and the integrated holding rib, and there is a jump rib 23 on the surface 12 of a certain unit element 10 and the back surface of another unit element 10. 13 connecting jump ribs 33 make up for the gaps on the same axis in the same row, and the jump ribs 23 and the connection jump ribs 33 in the flow path P are regularly and alternately arranged. As a result, three rows of jumping ribs arranged at predetermined intervals in the Y direction are formed between the integrated sealing ribs and the integrated holding ribs. Since the flying ribs 23 and the connecting flying ribs 33 are arranged on the same axis in the flow direction in this way, the air path formed by the flying ribs 23 and the connecting flying ribs 33 is cut into small pieces. Therefore, the frictional resistance of the airflow by the rib can be reduced, and each air passage can be formed in a shape that results in low pressure loss. Further, in this case, the jump ribs 23 of a certain unit element 10 occupy about half of the total of the jump ribs 23 and the connection jump ribs 33 formed in the flow path P.

このようにして形成される流路Ｐは、その向きによって、図１に示される第１の流路２になったり、第２の流路３になったりする。 The flow path P formed in this way becomes the first flow path 2 or the second flow path 3 shown in FIG.

ここで、単位素子１０の表面１２と裏面１３に形成されるリブの配置について、図６と図７を参照しながら説明する。図６は、１枚の単位素子１０の構成の一例を表面側から見た図であり、図７は、図６を区画分けした図である。図６では、裏面側に設けられるリブに、ハッチングを付している。 Here, the arrangement of the ribs formed on the front surface 12 and the back surface 13 of the unit element 10 will be described with reference to FIGS. 6 and 7. FIG. 6 is a view of an example of the configuration of one unit element 10 as viewed from the front side, and FIG. 7 is a view obtained by dividing FIG. In FIG. 6, the rib provided on the back side is hatched.

図７に示されるように、単位素子１０の中心を通りＸ方向に延在する直線と、単位素子１０の中心を通りＹ方向に延在する直線とによって、単位素子１０を４つの区画Ａ〜Ｄに分割する。ここでは、４つに分割した領域の１つを区画Ａとし、そこから時計回りに区画Ｂ、区画Ｃ、区画Ｄとしている。 As shown in FIG. 7, the unit element 10 is divided into four sections A to A by a straight line extending in the X direction through the center of the unit element 10 and a straight line extending in the Y direction through the center of the unit element 10. Divide into D. Here, one of the four divided areas is defined as section A, and from there, section B, section C, and section D are clockwise.

この実施の形態では、区画ＡをＸＹ面内で１８０度回転させると、区画Ｃと同じ形状となる。同様に区画ＢをＸＹ平面内で１８０度回転させると、区画Ｄと同じ形状となる。つまり、区画Ａ，Ｂは、それぞれ区画Ｃ，Ｄと回転対称の構造を有している。 In this embodiment, when the section A is rotated 180 degrees in the XY plane, the same shape as the section C is obtained. Similarly, when the section B is rotated 180 degrees in the XY plane, the same shape as the section D is obtained. That is, the sections A and B have a rotationally symmetric structure with the sections C and D, respectively.

また、区画Ａと区画Ｂ（同様に区画Ｃと区画Ｄ）とは、それぞれ異なる形状を有している。たとえば、区画ＡをＸＹ面内で９０度回転させてＢに重ねると、図５（積層した際に形成される流路Ｐを上面から投影した図）で示すように、流れ方向と並行するように、飛びリブ２３と接続飛びリブ３３とが流路Ｐを形成する。このとき、上記したように、飛びリブ２３と接続飛びリブ３３とは干渉せず、仕切板１１の表面１２を基準としたときに、Ｙ方向に隣接して配置される飛びリブ２３と飛びリブ２３の間に接続飛びリブ３３が配置され、またはＹ方向に隣接して配置される接続飛びリブ３３と接続飛びリブ３３の間に飛びリブ２３が配置される。さらに、配置された飛びリブ２３と接続飛びリブ３３は、封止リブ２１，３１と保持リブ２２，３２との間の流路Ｐに、規則正しく互い違いに配置される。 The section A and the section B (similarly the section C and the section D) have different shapes. For example, when section A is rotated 90 degrees in the XY plane and overlapped with B, as shown in FIG. 5 (a view in which the flow path P formed when stacked is projected from the upper surface), it is parallel to the flow direction. In addition, the flying rib 23 and the connecting flying rib 33 form a flow path P. At this time, as described above, the flying ribs 23 and the connecting flying ribs 33 do not interfere with each other, and the flying ribs 23 and the flying ribs arranged adjacent to each other in the Y direction when the surface 12 of the partition plate 11 is used as a reference. The connecting jump ribs 33 are arranged between the connecting jump ribs 33 or between the connecting jump ribs 33 arranged adjacent to each other in the Y direction. Furthermore, the arranged jump ribs 23 and the connection jump ribs 33 are regularly and alternately arranged in the flow path P between the sealing ribs 21 and 31 and the holding ribs 22 and 32.

このように、同じ形状の単位素子１０を９０度回転して積層するだけで全熱交換素子１が得られるため、生産性が高い。また、９０度回転をせずに積層を試みると、上記したようにリブが干渉するため、誤積層防止となる。 Thus, the total heat exchange element 1 can be obtained simply by rotating the unit elements 10 having the same shape by 90 degrees and stacking them, so that the productivity is high. Further, if the stacking is attempted without rotating by 90 degrees, the ribs interfere as described above, thereby preventing erroneous stacking.

また、図８に示されるように、たとえば仕切板１１の表面の流路Ｐにおいて、飛びリブ２３と接続飛びリブ３３とが同軸上に形成される位置で、リブ間の仕切板１１がフリーになっている流れ方向のスパン（間隔）は、どの位置でも概略同一のαである。さらに、たとえば仕切板１１の裏面の流路Ｐにおいて、飛びリブ２３と接続飛びリブ３３とが同軸上に形成される位置で、リブ間の仕切板１１がフリーになっている流れ方向のスパン（間隔）は、どの位置でも概略同一のβである。このように、流れ方向に沿って、均一にリブの間隔を設けることで、仕切板１１の撓みを効率よく抑制することができる。 Further, as shown in FIG. 8, for example, in the flow path P on the surface of the partition plate 11, the partition plate 11 between the ribs is free at a position where the jump rib 23 and the connection jump rib 33 are formed coaxially. The span (interval) in the flow direction is substantially the same α at any position. Further, for example, in the flow path P on the back surface of the partition plate 11, the flow direction span (where the partition plate 11 between the ribs is free) at the position where the jump rib 23 and the connection jump rib 33 are formed coaxially. The interval is approximately the same β at any position. As described above, by uniformly providing the rib interval along the flow direction, the bending of the partition plate 11 can be efficiently suppressed.

ここで、仕切板１１として、気体遮蔽性があり透湿性のある、たとえば透湿樹脂と不織布などの基材を貼合わせた複合膜、叩解度を上げたパルプ繊維を用いてすいた紙に、潮解性の吸湿塩（たとえば、塩化リチウムや塩化カルシウムなど）を塗布したシート状の特殊加工紙などを用いることができる。 Here, as the partition plate 11, gas-shielding and moisture-permeable, for example, a composite film obtained by laminating a base material such as a moisture-permeable resin and a non-woven fabric, and paper made using pulp fibers with increased beating degree, A sheet-like specially processed paper coated with a deliquescent moisture-absorbing salt (for example, lithium chloride or calcium chloride) can be used.

また、封止リブ２１、保持リブ２２、飛びリブ２３、接続封止リブ３１、接続保持リブ３２および接続飛びリブ３３は、一体成形された樹脂によって構成され、仕切板１１に設けられる。 Further, the sealing rib 21, the holding rib 22, the jumping rib 23, the connection sealing rib 31, the connection holding rib 32, and the connection jumping rib 33 are made of an integrally molded resin and are provided on the partition plate 11.

つぎに、このような単位素子１０の作製方法について説明する。単位素子１０の表面・裏面の形状をキャビティ・コアにそれぞれ掘り込んである成形金型を用意する。この成形金型に仕切板１１を挟み成形することで単位素子１０の形状が得られる。このとき、成形樹脂は、たとえば図９に示されるように、仕切板１１の表面に設けられた位置決め機構を構成する間隙２２ｃの位置からゲートで注入する。注入された樹脂は保持リブ２２、接続保持リブ３２を単位素子１０の外側に向かって放射状に流れる。保持リブ２２を流れる樹脂は、仕切板１１を破って途中に存在する接続飛びリブ３３に流れ込み、ついで飛びリブ２３と伝って（場合によってはさらに接続飛びリブ３３、飛びリブ２３を何度か繰返し伝って）最終的に再外側の接続封止リブ３１に流れる。 Next, a method for manufacturing such a unit element 10 will be described. A molding die is prepared in which the shapes of the front and back surfaces of the unit element 10 are dug into the cavity and the core, respectively. The shape of the unit element 10 is obtained by sandwiching and molding the partition plate 11 in this molding die. At this time, as shown in FIG. 9, for example, the molding resin is injected at the gate from the position of the gap 22c constituting the positioning mechanism provided on the surface of the partition plate 11. The injected resin flows radially through the holding rib 22 and the connection holding rib 32 toward the outside of the unit element 10. The resin flowing through the holding rib 22 breaks the partition plate 11 and flows into the connecting jump rib 33 existing on the way, and then travels to the jump rib 23 (in some cases, the connection jump rib 33 and the jump rib 23 are repeated several times. And finally flow to the outer connection sealing rib 31.

また同様に、ゲートから注入された樹脂は接続保持リブ３２を流れ、仕切板１１を破って途中にある飛びリブ２３に流れ込み、ついで接続飛びリブ３３と伝って（場合によってはさらに飛びリブ２３、接続飛びリブ３３を何度か繰返し伝って）最終的に再外側の封止リブ２１に流れる。 Similarly, the resin injected from the gate flows through the connection holding rib 32, breaks the partition plate 11, flows into the flying rib 23 in the middle, and then travels to the connecting flying rib 33 (in some cases, the flying rib 23, It finally flows to the outer sealing rib 21 (repeated several times through the connecting jump rib 33).

その後、樹脂を固化させることで、図９に示されるように、封止リブ２１、保持リブ２２、飛びリブ２３、接続封止リブ３１、接続保持リブ３２および接続飛びリブ３３が一体的に仕切板１１の両面に形成された単位素子１０が形成される。このように、樹脂が仕切板１１を破りながら縫うように流れていくので、特に破られた箇所については、樹脂と仕切板１１の接合強度が非常に強く、環境ストレス耐力を得ることができる。 Thereafter, by solidifying the resin, as shown in FIG. 9, the sealing rib 21, the holding rib 22, the jumping rib 23, the connection sealing rib 31, the connection holding rib 32 and the connection jumping rib 33 are integrally partitioned. Unit elements 10 formed on both surfaces of the plate 11 are formed. As described above, the resin flows so as to sew while breaking the partition plate 11, and therefore, particularly at the broken portion, the bonding strength between the resin and the partition plate 11 is very strong, and environmental stress resistance can be obtained.

そして、作製された単位素子１０を、表面のリブの延在方向が、下に配置された単位素子１０の表面のリブの延在方向に対して９０度回転するように、Ｚ方向に配置する。このとき、下に配置された単位素子１０の表面の保持リブ２２の間隙２２ｃに、上に配置される単位素子１０の裏面の接続保持リブ３２の接続部３２ｃが嵌るように重ね合わせる。この処理を単位素子１０を所定の数重ねるまで行うことによって、全熱交換素子１が形成される。 Then, the manufactured unit element 10 is arranged in the Z direction so that the extending direction of the rib on the surface rotates 90 degrees with respect to the extending direction of the rib on the surface of the unit element 10 arranged below. . At this time, it is overlapped so that the connection portion 32c of the connection holding rib 32 on the back surface of the unit element 10 disposed above fits in the gap 22c of the holding rib 22 on the surface of the unit element 10 disposed below. By performing this process until a predetermined number of unit elements 10 are stacked, the total heat exchange element 1 is formed.

なお、保持リブ２２、接続保持リブ３２を増やすことで、単位素子１０の強度を増すことができる。図１０は、実施の形態による全熱交換素子を構成する単位素子の他の構成例を示す上面図であり、図１１は、図１０を区画分けした図である。この例では、一対の封止リブ（封止リブ２１と接続封止リブ３１とが一体化された封止リブ）間に、３本の保持リブを配置し、隣接する封止リブと保持リブとの間、または隣接する保持リブの間に、それぞれ３列の飛びリブ２３および接続飛びリブ３３を配置している。 Note that the strength of the unit element 10 can be increased by increasing the holding ribs 22 and the connection holding ribs 32. FIG. 10 is a top view showing another configuration example of the unit elements constituting the total heat exchange element according to the embodiment, and FIG. 11 is a diagram in which FIG. 10 is divided. In this example, three holding ribs are arranged between a pair of sealing ribs (sealing ribs in which the sealing ribs 21 and the connection sealing ribs 31 are integrated), and the adjacent sealing ribs and holding ribs are arranged. Three rows of jumping ribs 23 and connecting jumping ribs 33 are arranged between the adjacent holding ribs.

この場合でも、図１１の区画ＡをＸＹ面内で１８０度回転すると区画Ｃと一致し、区画ＢをＸＹ面内で１８０度回転すると区画Ｄと一致し、区画Ａと区画Ｂ（区画Ｃと区画Ｄ）とが一致しないように、保持リブ２２、飛びリブ２３、接続保持リブ３２および接続飛びリブ３３が配置される。この例では、各区画Ａ〜Ｄは、それぞれさらに小区画Ａ１〜Ａ４，Ｂ１〜Ｂ４，Ｃ１〜Ｃ４，Ｄ１〜Ｄ４に区分される。その結果、単位素子１０は、１６個の小区画に区分されることになる。 Even in this case, when section A in FIG. 11 is rotated 180 degrees in the XY plane, it coincides with section C, and when section B is rotated 180 degrees in the XY plane, it coincides with section D, and section A and section B (section C and section C). The holding rib 22, the jump rib 23, the connection holding rib 32 and the connection jump rib 33 are arranged so as not to coincide with the section D). In this example, each of the sections A to D is further divided into small sections A1 to A4, B1 to B4, C1 to C4, and D1 to D4. As a result, the unit element 10 is divided into 16 small sections.

各区画Ａ〜Ｄに属する小区画は、全て同じリブの配置を有している。すなわち、区画Ａを構成する小区画Ａ１〜Ａ４は、全て同じリブの配置を有しており、区画Ｂを構成する小区画Ｂ１〜Ｂ４は、全て同じリブの配置を有しており、区画Ｃを構成する小区画Ｃ１〜Ｃ４は、全て同じリブの配置を有しており、区画Ｄを構成する小区画Ｄ１〜Ｄ４は、全て同じリブの配置を有している。その結果、領域Ａと領域Ｃは回転対称の形状となり、領域Ｂと領域Ｄは回転対称の形状となる。 All of the small sections belonging to the sections A to D have the same rib arrangement. That is, the small sections A1 to A4 constituting the section A all have the same rib arrangement, and the small sections B1 to B4 constituting the section B all have the same rib arrangement, and the section C. All of the small sections C1 to C4 constituting the same section have the same rib arrangement, and all of the small sections D1 to D4 constituting the section D have the same rib arrangement. As a result, region A and region C have a rotationally symmetric shape, and region B and region D have a rotationally symmetric shape.

このように、単位素子１０の分割数を増加させても、仕切板１１を４分割した区画Ａ〜Ｄについて、上記した規則で配置を行うことによって、上記と同一の効果を得ることができる。一般的に、単位素子１０に形成する封止リブ２１，３１と保持リブ２２，３２との間の流路、または保持リブ２２，３２間の流路の数をｍとすると、小区画の数Ｎは、次式（１）で示される。
Ｎ＝ｍ² ・・・（１） Thus, even if the number of divisions of the unit element 10 is increased, the same effect as described above can be obtained by arranging the sections A to D obtained by dividing the partition plate 11 into four according to the above-described rules. Generally, if the number of channels between the sealing ribs 21 and 31 and the holding ribs 22 and 32 formed in the unit element 10 or the number of channels between the holding ribs 22 and 32 is m, the number of small sections N is represented by the following formula (1).
N = m ² (1)

このような形状を取ることで、生産性が高く、また仕切板１１の伸びを抑制しつつ性能が高い全熱交換素子１を得ることができる。なお、上記した説明では、単位素子１０は、正方形の形状の仕切板１１によって構成されているが、これに限定されるものではなく、上記した実施の形態の特徴を有するものであれば、矩形状の仕切板によって構成されていてもよい。また、上記した例では、仕切板１１の中心を通り、各辺に平行な直線によって各区画に分割していたが、仕切板１１を４等分することができ、１８０度回転させて同じ形状となるものであれば、分割の仕方は特に問われない。 By taking such a shape, the total heat exchange element 1 with high productivity and high performance while suppressing the elongation of the partition plate 11 can be obtained. In the above description, the unit element 10 is configured by the square-shaped partition plate 11. However, the unit element 10 is not limited to this, and any rectangular element can be used as long as it has the characteristics of the above-described embodiment. You may be comprised by the shape partition plate. In the above example, the partition plate 11 is divided into sections by straight lines that pass through the center of the partition plate 11 and are parallel to each side. However, the partition plate 11 can be divided into four equal parts and rotated by 180 degrees to have the same shape. If it becomes, it will not ask | require especially the method of a division | segmentation.

つぎに、実施の形態による全熱交換素子１を適用した全熱交換装置について説明する。図１２は、実施の形態による全熱交換素子を適用した全熱交換装置の概略構成を示す図である。 Below, the total heat exchange apparatus to which the total heat exchange element 1 by embodiment is applied is demonstrated. FIG. 12 is a diagram illustrating a schematic configuration of a total heat exchange device to which the total heat exchange element according to the embodiment is applied.

全熱交換装置１００の内部には、上記した全熱交換素子１が収容される。全熱交換装置１００の内部には、室外の空気を室内に給気するための給気流路１０２が、全熱交換素子１の第１の空気流路２を含めて形成される。また、全熱交換装置１００の内部には、室内の空気を室外に排気するための排気流路１０３が、全熱交換素子１の第２の空気流路３を含めて構成される。給気流路１０２には、室外から室内に向けた空気の流れを発生させる給気送風機１１０が設けられる。すなわち、給気送風機１１０は、室外から給気流路１０２（第１の流路２）を介して室内へ向かう気流を第１の気流１０６として発生させる。排気流路１０３には、室内から室外に向けた空気の流れを発生させる排気送風機１２０が設けられる。すなわち、排気送風機１２０は、室内から排気流路１０３（第２の流路３）を介して室外へ向かう気流を第２の気流１０７として発生させる。 The total heat exchange device 1 is accommodated in the total heat exchange device 100. Inside the total heat exchange device 100, an air supply channel 102 for supplying outdoor air into the room is formed including the first air channel 2 of the total heat exchange element 1. In addition, an exhaust flow path 103 for exhausting indoor air to the outside including the second air flow path 3 of the total heat exchange element 1 is configured inside the total heat exchange device 100. The air supply flow path 102 is provided with an air supply blower 110 that generates a flow of air from the outside to the room. In other words, the air supply blower 110 generates an air flow from the outside to the room as the first air flow 106 via the air supply flow path 102 (first flow path 2). The exhaust flow path 103 is provided with an exhaust blower 120 that generates a flow of air from the room toward the outside. That is, the exhaust blower 120 generates an air flow that goes from the room to the outside through the exhaust flow path 103 (second flow path 3) as the second air flow 107.

全熱交換装置１００が運転されると、給気送風機１１０と排気送風機１２０とが作動する。これにより、たとえば冷たくて乾燥した室外の空気が給気流（第１の気流１０６）として給気流路１０２に通され、暖かくて湿気の高い室内の空気が排気流（第２の気流１０７）として排気流路１０３に通される。給気流および排気流の各気流（２種の気流）が、全熱交換素子１の仕切板１１を隔てて流れる。このとき、仕切板１１を介して各気流の間で熱が伝わり、仕切板１１を水蒸気が透過することで、給気流と排気流との間で顕熱および潜熱の熱交換が行われる。これにより、給気流は暖められるとともに加湿されて室内に供給され、排気流は冷やされるとともに減湿されて室外へ排出される。したがって、全熱交換装置１００で換気を行うことで、室内の空調の冷暖房効率の損失を抑えて、室外と室内との空気を換気することができる。 When total heat exchanger 100 is operated, supply air blower 110 and exhaust air blower 120 operate. Thus, for example, cold and dry outdoor air is passed as a supply airflow (first airflow 106) through the air supply passage 102, and warm and humid indoor air is exhausted as an exhaust airflow (second airflow 107). It is passed through the flow path 103. Each airflow (two types of airflows) of the supply airflow and the exhaust airflow flows through the partition plate 11 of the total heat exchange element 1. At this time, heat is transmitted between the airflows via the partition plate 11, and water vapor passes through the partition plate 11, whereby sensible heat and latent heat are exchanged between the supply airflow and the exhaust stream. As a result, the supply airflow is warmed and humidified and supplied to the room, and the exhaust stream is cooled and dehumidified and discharged outside the room. Therefore, by performing ventilation with the total heat exchange device 100, it is possible to suppress the loss of the cooling and heating efficiency of the indoor air conditioning and to ventilate the air between the outside and the room.

この実施の形態では、矩形状の仕切板１１を、同じ形状の４つの区画に分割し、互いに隣接する２つの区画を、ＸＹ面内で１８０度回転させると、残りの２つの区画となるように、仕切板１１にリブを設けた。そして、リブとして、仕切板１１の端部に配置される封止リブ２１および接続封止リブ３１と、仕切板１１の面内で仕切板１１の辺に沿って配置される保持リブ２２および接続保持リブ３２と、封止リブ２１（接続封止リブ３１）と保持リブ２２（接続保持リブ３２）との間で、流路Ｐに沿って細切れ状態で設けられる飛びリブ２３および接続飛びリブ３３と、を設けた。これによって、仕切板１１とリブの接触面積を減らし、伝熱面積を大きくとることができるため、高性能である全熱交換素子１を得ることができるという効果を有する。また、その単位素子１０は、金型で仕切板１１の表裏面にリブを一体成形することで製造でき、仕切板１１の貼合わせを必要としないので、仕切板１１の貼り付け工程を減らすことができる。その結果、生産性を上げることができるという効果を奏する。 In this embodiment, when the rectangular partition plate 11 is divided into four sections having the same shape and two adjacent sections are rotated 180 degrees in the XY plane, the remaining two sections are formed. In addition, ribs were provided on the partition plate 11. And as a rib, the sealing rib 21 and the connection sealing rib 31 which are arrange | positioned at the edge part of the partition plate 11, and the holding rib 22 and the connection which are arrange | positioned along the edge of the partition plate 11 within the surface of the partition plate 11 Between the holding rib 32, the sealing rib 21 (connection sealing rib 31) and the holding rib 22 (connection holding rib 32), the jump rib 23 and the connection jump rib 33 provided along the flow path P in a chopped state. And provided. As a result, the contact area between the partition plate 11 and the rib can be reduced and the heat transfer area can be increased, so that the high-performance total heat exchange element 1 can be obtained. Further, the unit element 10 can be manufactured by integrally forming ribs on the front and back surfaces of the partition plate 11 with a mold, and does not require pasting of the partition plate 11, thereby reducing the step of attaching the partition plate 11. Can do. As a result, there is an effect that productivity can be increased.

通常、全熱交換素子１の性能を向上させるためには、単位素子１０を薄く作製し、同一高さ内に積層枚数を多く敷き詰める必要がある。しかし、本形状を用いることで、飛びリブ２３および接続飛びリブ３３の厚みを減らすことなく、かつ飛びリブ２３および接続飛びリブ３３と仕切板１１との接触面積を必要以上に増やすこともなく、樹脂流動性を確保することが可能になる。その結果、成形時のゲート点数削減や、成形樹脂の選定のしやすさなど、製造上の難易度も下げることができる。 Usually, in order to improve the performance of the total heat exchange element 1, it is necessary to make the unit element 10 thin and spread a large number of stacked layers within the same height. However, by using this shape, the thickness of the flying rib 23 and the connecting flying rib 33 is not reduced, and the contact area between the flying rib 23 and the connecting flying rib 33 and the partition plate 11 is not increased more than necessary. It becomes possible to ensure resin fluidity. As a result, it is possible to reduce manufacturing difficulty such as reduction in the number of gates during molding and ease of selection of molding resin.
