- the refrigerant flowing out from the outdoor heat exchanger 23 to the refrigerant pipe 62 flows through the port b and port c of the four-way valve 22 and the suction pipe 66, is sucked into the compressor 21, and is compressed again.

That is, the refrigerant that has flowed from the inlet pipe 63 into the heat exchange module 50c in the third row flows through the first outward path 50cD from the first upper header 81c toward the first lower header 82c. The refrigerant that has flowed into the first lower header 82c flows into the second lower header 82b, and then passes through the first return path 50bU arranged in the center of the heat exchange module 50b in the second row toward the second upper header 81b.

There are two round trips throughout the exchange modules 50c, 50b, and 50a. Therefore, the pressure loss cannot be reduced due to the increase in the number of times the refrigerant is turned back.

Description
(1)本発明の第1の観点は、熱交換器であって、冷媒が外部から流入する第1列の熱交換モジュールと、冷媒が外部へ流出する第2列の熱交換モジュールと、冷媒が外部へ流出する第3列の熱交換モジュールと、が通風方向に積層して配置され、前記第1列の熱交換モジュールから流入した冷媒を前記第2列の熱交換モジュール及び前記第3列の熱交換モジュールへ分流する分流モジュールと、を備えた熱交換器であって、前記第1列の熱交換モジュールが冷媒の往路を、前記第2列の熱交換モジュール及び前記第3列の熱交換モジュールの双方が冷媒の復路をそれぞれ構成し、これにより、冷媒の流路が前記熱交換器の冷媒が流入する入口と冷媒が流出する出口との間で一往復となる、ことを特徴とする。
以下、本発明の実施形態を、添付図面に基づいて詳細に説明する。なお、本発明は以下の実施形態に限定されることはなく、本発明の主旨を逸脱しない範囲で種々変形することが可能である。
まず、図1Aを参照して、室外機2を含む空気調和機1の冷媒回路について説明する。図1Aに示すように、本実施形態における空気調和機1は、屋外に設置される室外機2と、室内に設置され、室外機2に液管4及びガス管5で接続された室内機3を備えている。詳細には、室外機2の液側閉鎖弁25と室内機3の液管接続部33が液管4で接続されている。また、室外機2のガス側閉鎖弁26と室内機3のガス管接続部34がガス管5で接続されている。以上により、空気調和機1の冷媒回路10が形成される。
まずは、室外機2について説明する。室外機2は、圧縮機21と、四方弁22と、室外熱交換器23と、膨張弁24と、液管4が接続された液側閉鎖弁25と、ガス管5が接続されたガス側閉鎖弁26と、室外ファン27を備えている。そして、室外ファン27を除くこれら各装置が後述する各冷媒配管で相互に接続されて、冷媒回路10の一部をなす室外機冷媒回路10aを形成している。なお、圧縮機21の冷媒吸入側には、アキュムレータ(不図示)が設けられてもよい。
次に、図1Aを用いて、室内機3について説明する。室内機3は、室内熱交換器31と、室内ファン32と、液管4の他端が接続された液管接続部33と、ガス管5の他端が接続されたガス管接続部34を備えている。そして、室内ファン32を除くこれら各装置が以下で詳述する各冷媒配管で相互に接続されて、冷媒回路10の一部をなす室内機冷媒回路10bを形成している。
次に、本実施形態における空気調和機1の空調運転時の冷媒回路10における冷媒の流れや各部の動作について、図1Aを用いて説明する。以下では、図中、実線で示した冷媒の流れに基づいて、室内機3が暖房運転を行う場合について説明する。なお、破線で示した冷媒の流れが冷房運転を示している。
本実施形態に係る室外熱交換器23(以下、熱交換器23という)は、扁平管(伝熱管)を備えた熱交換モジュール50を3列に設けている。
以下、熱交換器23とその内部での冷媒の流路について、従来の熱交換器と比較しながら図2から図8を用いて説明する。
まず、従来の熱交換器23について、図8を用いて説明する。熱交換器23は、図8に示すように、3列の熱交換モジュール50(50a,50b,50c)を備えている。各列の両端には、上ヘッダ81(81a,81b,81c)と、下ヘッダ82(82a,82b,82c)とが設けられている。第1上ヘッダ81cには、冷媒が外部から流入する冷媒配管63(以下、入口管63と呼称する)が接続されており、第3上ヘッダ81aには、冷媒が外部へ流出する冷媒配管62(以下、出口管62と呼称する)が設けられている。通風方向の風上側は、第1列の熱交換モジュール50a側に設定されている。第1列の熱交換モジュール50aの風下側には、第2列の熱交換モジュール50bと第3列の熱交換モジュール50cが順に並んでいる。なお、添え字「a,b,c」は、通風方向の風上側からみて順に付与している。
次に、復路である2列の熱交換モジュール50b、50cに対し、手前側ヘッダ84において冷媒を分流して折り返す手段について、説明する。熱交換量を多くするために熱交換モジュール50の列数を3列にした場合、並列となる第2列の熱交換モジュール50bと第3列の熱交換モジュール50cとでは、通過する空気の温度が異なる。具体的には、通風方向の風下側に位置する第3列の熱交換モジュール50cには、第2列の熱交換モジュール50bを通過した空気が通過する。そのため、第3列の熱交換モジュール50cでは空気と冷媒との温度差が比較的小さくなり、熱交換量に差が生じる。
