Title (EN) HEAT EXCHANGER UNIT AND AIR CONDITIONER USING SAME
(FR) UNITÉ D'ÉCHANGEUR DE CHALEUR ET CLIMATISEUR L'UTILISANT
(JA) 熱交換器ユニット、及びそれを用いた空気調和機
Abstract:
(EN) The present invention addresses the problem of providing a heat exchanger unit that achieves equivalent heat exchange performance even when the direction of an airflow traversing a heat exchange section reverses. Provided are a heat exchanger unit and an air conditioner using said heat exchanger unit, wherein, in a heat exchange section, groups of a plurality of heat transfer tubes that are lined up in L or more stages in a direction intersecting an airflow are arranged in M columns in the direction of the airflow, and the plurality of heat transfer tubes form N paths, where M < N. By establishing one or more paths making at least one pass through all of the columns and weakening the impact of a column having heat exchange performance that increases only on airflow in one direction that passes through the heat exchange section, the range of fluctuations is reduced in heat exchange performance when the direction of the airflow passing through the heat exchange section is reversed.
(FR) La présente invention aborde le problème de la fourniture d'une unité d'échangeur de chaleur qui obtient une performance d'échange de chaleur équivalente même lorsque la direction d'un flux d'air traversant une section d'échange de chaleur s'inverse. L'invention concerne une unité d'échangeur de chaleur et un climatiseur l'utilisant , dans laquelle, dans une section d'échange de chaleur, des groupes d'une pluralité de tubes de transfert de chaleur qui sont alignés en L ou en plusieurs étages dans une direction croisant un flux d'air sont agencés en M colonnes dans la direction du flux d'air, et la pluralité de tubes de transfert de chaleur forment N trajets, où M < N. En établissant un ou plusieurs chemins faisant au moins un passage à travers toutes les colonnes et affaiblissant l'impact d'une colonne ayant une performance d'échange de chaleur qui augmente uniquement avec le flux d'air dans une direction qui passe à travers la section d'échange de chaleur, la plage de fluctuations est réduite en performance d'échange de chaleur lorsque la direction du flux d'air traversant la section d'échange de chaleur est inversée.
(JA) 本発明の課題は、熱交換部を横切る気流の向きが逆向きとなっても、同等の熱交換性能を実現する熱交換器ユニットを提供することにある。熱交換器ユニット及びこの熱交換器ユニットを用いた空気調和機において、熱交換部では、空気流と交差する方向にL段以上並ぶ複数の伝熱管の群が空気流の方向にM個の列で配置され、複数の伝熱管がN個のパスを形成し、M<Nである。そして、全ての列を少なくとも1回通るパスの数を1つ以上設定し、熱交換部を通過する一方向の気流に対してのみ熱交換性能が上がる列の影響を弱めることにより、熱交換部を通過する空気流の方向が逆転したときの熱交換性能の変動幅を縮小する。
