Abstract
Description
図1は、本発明の実施の形態1にかかる全熱交換素子10の概略構成を示す外観斜視図である。図2は、本実施の形態1にかかる全熱交換素子10における、間隔保持部2と、間隔保持部2を挟んで配置される仕切部1とを抜き出して示した縦断面図である。全熱交換素子10は、層状に設けられた第1の流路である第1の空気流路4と、層状に設けられた第2の流路である第2の空気流路5と、第1の空気流路4と第2の空気流路5との間を仕切る平板状の仕切部1と、を備える。また、全熱交換素子10は、第1の空気流路4と第2の空気流路5とを形成して仕切部1同士の間隔を保持するコルゲート形状の間隔保持部2と、仕切部1と間隔保持部2とを接合する接合部3と、を備える。コルゲート形状とは、山部と谷部とで構成される波形の形状である。
図11は、本発明の実施の形態2にかかる全熱交換素子の間隔保持部2と、間隔保持部2を挟んで配置される仕切部31とを抜き出して示した縦断面図である。本実施の形態2にかかる全熱交換素子は、仕切部1の代わりに仕切部31を備える点が、上述した実施の形態1にかかる全熱交換素子10と異なる。本実施の形態2にかかる全熱交換素子の仕切部31以外の構成は、上述した実施の形態1にかかる全熱交換素子10と同じであるため、詳細な説明は省略する。
つぎに、図12を用いて、上述した実施の形態1にかかる全熱交換素子10を備える全熱交換器100について説明する。図12は、本発明の実施の形態3にかかる全熱交換器100の概略構成を示す図である。全熱交換器100の内部には、上述した実施の形態1にかかる全熱交換素子10が収容される。全熱交換器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44が、全熱交換素子10の第1の空気流路4を含めて形成される。また、全熱交換器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45が、全熱交換素子10の第2の空気流路5を含めて構成される。給気流路44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46が設けられる。排気流路45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47が設けられる。
