Description

本開示は、熱交換器に関するものである。 The present disclosure relates to heat exchangers.

特許文献１には、換気装置に用いられる熱交換素子が開示されている。この熱交換素子は、給気と排気を熱交換させる熱交換器である。この熱交換器では、樹脂枠と伝熱板とが交互に複数ずつ積層される。この熱交換器では、樹脂枠と伝熱板の積層方向に、給気側の空気流路と排気側の空気流路が交互に形成される。隣り合う空気流路は、伝熱板によって仕切られる。そして、この熱交換器では、給気側の空気流路を流れる空気と、排気側の空気流路を流れる空気とが、伝熱板を介して顕熱と潜熱（水分）を交換する。 Patent Document 1 discloses a heat exchange element used in a ventilation device. This heat exchange element is a heat exchanger that exchanges heat between supply air and exhaust gas. In this heat exchanger, a plurality of resin frames and heat transfer plates are alternately laminated. In this heat exchanger, an air flow path on the air supply side and an air flow path on the exhaust side are alternately formed in the stacking direction of the resin frame and the heat transfer plate. Adjacent air channels are separated by a heat transfer plate. Then, in this heat exchanger, the air flowing through the air flow path on the air supply side and the air flowing through the air flow path on the exhaust side exchange sensible heat and latent heat (moisture) via the heat transfer plate.

In the main heat exchange section (11) of the heat exchanger (10), the air supply flowing through the first flow path (21) and the exhaust gas flowing through the second flow path (51) flow in opposite directions.

熱交換器（10）では、第１流路（21）を流れる給気と第２流路（51）を流れる排気との間で、顕熱と潜熱（水分）の交換が行われる。熱交換器（10）では、給気と排気のうち温度が高い方から温度が低い方へ熱が移動する。また、熱交換器（10）では、給気と排気のうち湿度が高い方から湿度が低い方へ水分が移動する。 In the heat exchanger (10), sensible heat and latent heat (moisture) are exchanged between the supply air flowing through the first flow path (21) and the exhaust gas flowing through the second flow path (51). In the heat exchanger (10), heat is transferred from the higher temperature side of the supply air and the exhaust air to the lower temperature side. Further, in the heat exchanger (10), moisture moves from the higher humidity side of the supply air and the exhaust air to the lower humidity side.
