Description
本実施形態の全熱交換素子(30)は、換気装置(10)に設けられる。ここでは、全熱交換素子(30)を備える換気装置(10)について説明する。
図2および図3に示すように、全熱交換素子(30)は、第1空気流路(36)と第2空気流路(37)とが複数ずつ形成された直交流型の熱交換器である。全熱交換素子(30)は、仕切板(31)と間隔保持部材(34)とを交互に複数ずつ積層することによって、全体として四角柱状に形成される。全熱交換素子(30)において、隣り合う仕切板(31)同士の間隔は、間隔保持部材(34)によって実質的に一定に保持される。
例えば夏季のように、室外空気の水蒸気圧よりも室内空気の水蒸気圧の方が低い状態を考える。このような状態では、給気側通路(21)に第2空気流路(37)が連通し、かつ排気側通路(22)に第1空気流路(36)が連通するように全熱交換素子(30)が配置される。これにより、排気側通路(22)に比べて水蒸気圧が高い室外空気が流れる給気側通路(21)を多孔質基材(32)の第2主面(32b)が向くと共に、給気側通路(21)に比べて水蒸気圧が低い室内空気が流れる排気側通路(22)を多孔質基材(32)の第1主面(32a)が向く。
本実施形態の全熱交換素子(30)は、第1主面(32a)および第2主面(32b)を有する多孔質基材(32)と、該多孔質基材(32)における上記第1主面(32a)側に設けられた透湿膜(33)とをそれぞれ有し、互いに間隔をおいて並んだ複数の仕切板(31)を備え、複数の上記仕切板(31)の間に、空気が流れる第1空気流路(36)と、該第1空気流路(36)に比べて水蒸気圧が高い空気が流れる第2空気流路(37)とが交互に形成されており、複数の上記仕切板(31)は、上記多孔質基材(32)の上記第1主面(32a)が上記第1空気流路(36)を向き、かつ上記多孔質基材(32)の上記第2主面(32b)が上記第2空気流路(37)を向いている。この全熱交換素子(30)は、上述の発見を応用したものであり、複数の仕切板(31)の間に交互に形成される第1空気流路(36)および第2空気流路(37)のうち第1空気流路(36)を第1主面(32a)が向くように、かつ第1空気流路(36)および第2空気流路(37)のうち第2空気流路(37)を第2主面(32b)が向くように仕切板(31)を配置するものである。これにより、第1空気流路(36)の水蒸気圧よりも第2空気流路(37)の水蒸気圧が高くなる状態において、多孔質基材(32)および透湿膜(33)を備えた仕切板(31)における透湿移動量を最大限に高め、当該仕切板(31)を有効活用することができる。

32 多孔質基材(基材)
32a 第1主面
32b 第2主面
33 透湿膜
