Description
図1は、実施の形態1にかかる熱交換換気装置1を示す概略正面図であり、図2は、実施の形態1にかかる熱交換換気装置1を示す概略平面図である。熱交換換気装置1は、天井裏の空間に取り付けられ、ダクト(図示せず)を通じて給排気する全熱交換形の換気装置である。熱交換換気装置1は、外郭を形成する筐体10と、筐体10内に挿抜可能に収納される角柱状(実施の形態1では、四角柱状)の熱交換器20と、筐体10内で熱交換器20を支持する複数の支持部材30とを備える。
図16は、実施の形態2にかかる熱交換換気装置1Bを示す概略平面図である。図示するように、熱交換換気装置1Bは、実施の形態1にかかる熱交換換気装置1の構成に加えて、排気流路内を流れる排気流を、熱交換器20を通過させずに、熱交換器20の上流側から当該熱交換器20の下流側へと導くバイパス流路Vを備え、バイパス流路Vを形成するための分離板19を備える。排気流を熱交換器20へ流すか、バイパス流路Vへ流すかは、流路を切り替える図示しないダンパーによって切り替えられる。分離板19は、熱交換器20よりも第4側板14側に設けられ、筐体10に対して固定される。熱交換換気装置1Bにおいて、熱交換器20は、筐体10に取り付けられた際に、第4側板14側の端面が分離板19に当接する。なお、本実施形態において、バイパス流路Vは、排気流に対して設けたが、バイパス流路Vを給気流に対して設けてもよい。その場合、分離板19は、給気流路内を流れる給気流を、熱交換器20を通過させずに、熱交換器20の上流側から当該熱交換器20の下流側へと導くバイパス流路Vを形成する。また、排気流を吸い込む室外側吸込口111からバイパス流路Vへ空気を導く手段、および給気流を吸い込む室内側吸込口121からバイパス流路Vへ空気を導く手段は、図示しないが、各吸込口からバイパス流路Vへと空気を誘導することさえできれば、いかなる構造であってもよい。
