前記第1熱交換部は、前記蒸発運転時における冷媒の流れ方向に対して前記第2熱交換部よりも上流に配置されている。
以下、本発明の実施形態について、図面を参照しながら説明する。なお、この実施形態によって本発明が限定されるものではない。
図1は、本発明の第1実施形態に係る空気調和機の構成を模式的に示す説明図である。図1に示すように、本第1実施形態に係る空気調和機1は、室外に設置される室外機2と、室内に設置される室内機4とを備えている。
図5は、本発明の第2実施形態に係る空気調和機が備える室外熱交換器の構成を模式的に示す説明図である。本第2実施形態に係る空気調和機が前記第1実施形態に係る空気調和機と異なる点は、室外熱交換器10Aが、室外ファンから送風される空気の流れに対して、風上側、中央、風下側の3列の管配列を有し、第1熱交換部の冷媒流路が風上側よりも風下側の方が多くなっている点である。なお、図5において、実線矢印は、室外熱交換器10Aが蒸発器として使用される蒸発運転時(暖房運転時)の冷媒の流れ方向を示している。また、図5において、破線矢印は、室外熱交換器10Aが凝縮器として使用される凝縮運転時(冷房運転時)の冷媒の流れ方向を示している。
