　しかしながら、特許文献１に記載されたルームエアコン用室内機では、熱交換器は、ファンよりも空気の流れの上流に配置される。従って、熱交換器は、ファンによって吹出口を通して外部に空気を送り出す際に、空気の整流に寄与することができない。一方、ルームエアコン用室内機において外部に空気を送り出す際に、空気の整流を効果的に実現することが要望されている。 However, in the indoor unit for room air conditioner described in Patent Document 1, the heat exchanger is arranged upstream of the air flow than the fan. Therefore, the heat exchanger cannot contribute to air rectification when air is sent to the outside through the air outlet by the fan. On the other hand, when air is sent to the outside in an indoor unit for room air conditioners, it is desired to effectively realize air rectification.
　本発明は上記課題に鑑みてなされたものであり、その目的は、吹出口を通して外部に空気を送り出す際に、空気の整流を効果的に行うことのできる空気調和機を提供することにある。 The present invention has been made in view of the above problems, and an object of the present invention is to provide an air conditioner capable of effectively performing air rectification when air is sent to the outside through an air outlet.
　本発明の一局面によれば、空気調和機は、ファンと、第１熱交換部とを備える。ファンは、空気を吸い込み、吸い込んだ前記空気を、吹出口を通して外部に送り出す。第１熱交換部は、前記ファンよりも、前記空気の流れの下流に位置し、熱交換を行う。前記第１熱交換部は、複数の扁平管と、第１ヘッダ管と、第２ヘッダ管とを含む。複数の扁平管の各々が第１方向に沿って延びており、複数の扁平管が前記第１方向に直交する第２方向に沿って並んでいる。第１ヘッダ管は、前記複数の扁平管の前記第１方向の一端に接続され、前記第１方向に直交する所定方向に沿って延びる。第２ヘッダ管は、前記複数の扁平管の前記第１方向の他端に接続され、前記所定方向に沿って延びる。前記第１熱交換部は、前記吹出口を向いている。 According to one aspect of the present invention, the air conditioner includes a fan and a first heat exchange unit. The fan sucks air and sends the sucked air to the outside through the air outlet. A 1st heat exchange part is located downstream of the flow of the air rather than the fan, and performs heat exchange. The first heat exchange unit includes a plurality of flat tubes, a first header tube, and a second header tube. Each of the plurality of flat tubes extends along the first direction, and the plurality of flat tubes are arranged along a second direction orthogonal to the first direction. The first header pipe is connected to one end of the plurality of flat pipes in the first direction, and extends along a predetermined direction orthogonal to the first direction. The second header pipe is connected to the other end of the plurality of flat pipes in the first direction and extends along the predetermined direction. The first heat exchange unit faces the blower outlet.

　次に、図２及び図３を参照して、第１熱交換部７を詳細に説明する。図３は、第１熱交換部７を示す正面図である。図２及び図３に示すように、第１熱交換部７は、複数の扁平管２１と、第１ヘッダ管２３Ｌと、第２ヘッダ管２３Ｒとを含む。複数の扁平管２１の各々は、第１方向Ｄ１に沿って延びており、第２方向Ｄ２に沿って並んでいる。第２方向Ｄ２は第１方向Ｄ１に直交する。 Next, the first heat exchange unit 7 will be described in detail with reference to FIGS. FIG. 3 is a front view showing the first heat exchange unit 7. As shown in FIGS. 2 and 3, the first heat exchange unit 7 includes a plurality of flat tubes 21, a first header tube 23L, and a second header tube 23R. Each of the plurality of flat tubes 21 extends along the first direction D1 and is aligned along the second direction D2. The second direction D2 is orthogonal to the first direction D1.
　複数の扁平管２１の各々は、複数の冷媒流路２１ａを有する。冷媒は冷媒流路２１ａを流れる。複数の扁平管２１の各々において、複数の冷媒流路２１ａは、扁平管２１の幅方向（以下、「幅方向ＷＤ」と記載する。）に一直線に並んでいる。扁平管２１の幅方向ＷＤは、第１方向Ｄ１と第２方向Ｄ２との双方に直交する方向である。冷媒流路２１ａは、第１方向Ｄ１に沿って延びている。なお、図３は正面図であるため、冷媒流路２１ａは図３には表れていない。 Each of the plurality of flat tubes 21 has a plurality of refrigerant channels 21a. The refrigerant flows through the refrigerant flow path 21a. In each of the plurality of flat tubes 21, the plurality of refrigerant channels 21 a are arranged in a straight line in the width direction of the flat tubes 21 (hereinafter referred to as “width direction WD”). The width direction WD of the flat tube 21 is a direction orthogonal to both the first direction D1 and the second direction D2. The refrigerant flow path 21a extends along the first direction D1. Since FIG. 3 is a front view, the refrigerant flow path 21a does not appear in FIG.
　扁平管２１は、一対の主面２１０と、一対の湾曲面２１１とを有する。一対の主面２１０は、冷媒流路２１ａを介して互いに対向し、第２方向Ｄ２に直交する。主面２１０は平坦面である。一対の湾曲面２１１は、冷媒流路２１ａを介して互いに対向する。湾曲面２１１は、扁平管２１の外部に向かって凸状に湾曲している。 The flat tube 21 has a pair of main surfaces 210 and a pair of curved surfaces 211.

The pair of curved surfaces 211 oppose each other via the refrigerant flow path 21a. The curved surface 211 is curved in a convex shape toward the outside of the flat tube 21.
　第１ヘッダ管２３Ｌと第２ヘッダ管２３Ｒとは、実質的に平行に配置される。第１ヘッダ管２３Ｌは、複数の扁平管２１の第１方向Ｄ１の一端に接続され、所定方向ＰＤに沿って延びる。実施形態１では、所定方向ＰＤは、第１方向Ｄ１に直交し、第２方向Ｄ２と実質的に平行である。第１ヘッダ管２３Ｌは、冷媒流入部２３ａと、冷媒流出部２３ｂと、冷媒流路（不図示）とを有する。冷媒流入部２３ａは、第１ヘッダ管２３Ｌの所定方向ＰＤの一端部に配置される。冷媒流出部２３ｂは、第１ヘッダ管２３Ｌの所定方向ＰＤの他端部に配置される。第１ヘッダ管２３Ｌの冷媒流路は、所定方向ＰＤに沿って延びており、扁平管２１の冷媒流路２１ａの第１方向Ｄ１の一端と接続される。 The first header pipe 23L and the second header pipe 23R are arranged substantially in parallel. The first header tube 23L is connected to one end of the plurality of flat tubes 21 in the first direction D1, and extends along the predetermined direction PD. In the first embodiment, the predetermined direction PD is orthogonal to the first direction D1 and substantially parallel to the second direction D2. The first header pipe 23L includes a refrigerant inflow portion 23a, a refrigerant outflow portion 23b, and a refrigerant flow path (not shown). The refrigerant inflow portion 23a is disposed at one end of the first header pipe 23L in the predetermined direction PD. The refrigerant outflow portion 23b is disposed at the other end portion in the predetermined direction PD of the first header pipe 23L. The refrigerant flow path of the first header pipe 23L extends along the predetermined direction PD, and is connected to one end of the refrigerant flow path 21a of the flat pipe 21 in the first direction D1.
　第２ヘッダ管２３Ｒは、複数の扁平管２１の第１方向Ｄ１の他端に接続され、所定方向ＰＤに沿って延びる。第２ヘッダ管２３Ｒは冷媒流路（不図示）を有する。第２ヘッダ管２３Ｒの冷媒流路は、所定方向ＰＤに沿って延びており、扁平管２１の冷媒流路２１ａの第１方向Ｄ１の他端と接続される。 The second header tube 23R is connected to the other end of the plurality of flat tubes 21 in the first direction D1, and extends along the predetermined direction PD. The second header pipe 23R has a refrigerant flow path (not shown). The refrigerant flow path of the second header pipe 23R extends along the predetermined direction PD and is connected to the other end of the refrigerant flow path 21a of the flat pipe 21 in the first direction D1.
　冷媒流入部２３ａから流入した冷媒は、第１ヘッダ管２３Ｌの冷媒流路、扁平管２１の冷媒流路２１ａ、及び第２ヘッダ管２３Ｒの冷媒流路を流れて、冷媒流出部２３ｂから流出する。 The refrigerant flowing in from the refrigerant inflow portion 23a flows through the refrigerant flow path of the first header pipe 23L, the refrigerant flow path 21a of the flat tube 21, and the refrigerant flow path of the second header pipe 23R, and flows out of the refrigerant outflow portion 23b. .
　第１熱交換部７は、複数のコルゲートフィン２５をさらに有していてもよい。複数のコルゲートフィン２５の各々は、互いに第２方向Ｄ２に隣り合う扁平管２１の間に配置される。複数のコルゲートフィン２５の各々は、波形に折り曲げられた形状を有する。 The first heat exchange unit 7 may further include a plurality of corrugated fins 25. Each of the plurality of corrugated fins 25 is disposed between the flat tubes 21 adjacent to each other in the second direction D2. Each of the plurality of corrugated fins 25 has a shape bent into a waveform.
　図２に示すように、第１熱交換部７は、ファン５と吹出口１１との間に配置される。具体的には、第１熱交換部７は、ファン５よりも、空気の流れの下流に位置する。そして、第１熱交換部７は、吹出口１１を向いている。従って、吹出口１１を通して筐体１の外部に空気を送り出す際に、複数の扁平管２１は、空気を整流することができる。つまり、複数の扁平管２１の各々は空気を整流する羽根として機能し、複数の扁平管２１はルーバーとして機能する。その結果、実施形態１によれば、空気調和機１００は、吹出口１１を通して外部に空気を送り出す際に、空気の整流を効果的に行うことができる。特に、実施形態１では、第１熱交換部７は、吹出口１１を通して、パネルに向いている。 As shown in FIG. 2, the first heat exchange unit 7 is disposed between the fan 5 and the air outlet 11. Specifically, the first heat exchange unit 7 is located downstream of the air flow with respect to the fan 5. And the 1st heat exchange part 7 has faced the blower outlet 11. FIG. Therefore, when sending air out of the housing 1 through the air outlet 11, the plurality of flat tubes 21 can rectify the air. That is, each of the plurality of flat tubes 21 functions as a blade that rectifies air, and the plurality of flat tubes 21 functions as a louver. As a result, according to the first embodiment, the air conditioner 100 can effectively rectify the air when the air is sent to the outside through the air outlet 11. In particular, in Embodiment 1, the 1st heat exchange part 7 is suitable for the panel through the blower outlet 11. FIG.
　具体的には、複数の扁平管２１の各々の一対の主面２１０が、空気Ａ１を整流して、整流後の空気Ａ２を吹出口１１に向けて送り出す。特に、扁平管２１の一対の湾曲面２１１のうち、空気の流れの上流に位置する湾曲面２１１は、空気の流れの上流に向かって凸状に湾曲している。従って、扁平管２１による流路抵抗を低減しつつ、扁平管２１によって効果的に空気を整流できる。 Specifically, the pair of main surfaces 210 of each of the plurality of flat tubes 21 rectifies the air A1 and sends the rectified air A2 toward the outlet 11. In particular, of the pair of curved surfaces 211 of the flat tube 21, the curved surface 211 located upstream of the air flow is curved in a convex shape toward the upstream of the air flow. Therefore, air can be effectively rectified by the flat tube 21 while reducing the flow resistance by the flat tube 21.
　引き続き図２及び図３を参照して、第１熱交換部７をさらに詳細に説明する。図３に示すように、第１熱交換部７は、サイドフロータイプのパラレルフロー型熱交換器である。従って、扁平管２１の延びる第１方向Ｄ１は水平方向と実質的に平行である。つまり、複数の扁平管２１の各々は水平方向に沿って延びている。従って、実施形態１によれば、複数の扁平管２１によって、垂直方向（具体的には、上下方向）に空気を整流できる。 The first heat exchange unit 7 will be described in further detail with reference to FIGS. 2 and 3. As shown in FIG. 3, the 1st heat exchange part 7 is a parallel flow type heat exchanger of a side flow type. Accordingly, the first direction D1 in which the flat tube 21 extends is substantially parallel to the horizontal direction. That is, each of the plurality of flat tubes 21 extends in the horizontal direction. Therefore, according to the first embodiment, air can be rectified in the vertical direction (specifically, the vertical direction) by the plurality of flat tubes 21.
　そして、図２に示すように、第１方向Ｄ１（図３）から扁平管２１を見たときに、扁平管２１は、水平方向ＨＤに対して傾斜している。従って、実施形態１によれば、複数の扁平管２１は、空気Ａ１を整流して、水平方向ＨＤに対して傾斜した方向に空気Ａ２を送り出すことができる。また、空気Ａ２が水平方向ＨＤに送り出されてパネル３に当たる場合と比較して、パネル３による空気Ａ２に対する流路抵抗を低減できる。 As shown in FIG. 2, when the flat tube 21 is viewed from the first direction D1 (FIG. 3), the flat tube 21 is inclined with respect to the horizontal direction HD. Therefore, according to the first embodiment, the plurality of flat tubes 21 can rectify the air A1 and send out the air A2 in a direction inclined with respect to the horizontal direction HD. In addition, the flow resistance of the panel 3 to the air A2 can be reduced as compared with the case where the air A2 is sent in the horizontal direction HD and hits the panel 3.
　実施形態１では、扁平管２１は、水平方向ＨＤに対して下方に向けて吹出口１１側に傾斜している。従って、扁平管２１は、水平方向ＨＤに対して下方に向けて吹出口１１側に傾斜した方向に、空気Ａ２を送り出すことができる。その結果、扁平管２１の傾斜は、暖かい空気を室内に送り出す暖房運転時の空気調和機１００に好適である。さらに、複数の扁平管２１によって整流された空気Ａ２の一部は、パネル３によって、パネル３の下方に向けて送り出される。従って、室内を更に効果的に暖めることができる。 In Embodiment 1, the flat tube 21 is inclined toward the outlet 11 toward the lower side with respect to the horizontal direction HD. Therefore, the flat tube 21 can send out the air A2 in a direction inclined downward toward the outlet 11 with respect to the horizontal direction HD. As a result, the inclination of the flat tube 21 is suitable for the air conditioner 100 during heating operation for sending warm air into the room. Further, part of the air A <b> 2 rectified by the plurality of flat tubes 21 is sent out downward of the panel 3 by the panel 3. Therefore, the room can be warmed more effectively.
　具体的には、扁平管２１は、水平方向ＨＤに対して、傾斜角θａだけ下方に向けて吹出口１１側に傾斜している。傾斜角θａは、４５度よりも小さいことが好ましい。例えば、冷房運転時に、扁平管２１によって凝縮した水滴が落下することを抑制でき、水滴をコルゲートフィン２５に沿って排出し易いためである。また、傾斜角θａは、５度以上１０度以下であることが更に好ましい。例えば、冷房運転時に、扁平管２１によって凝縮した水滴をコルゲートフィン２５に沿って効果的に排出できるからである。また、傾斜角θａが大きすぎると、例えば、冷房運転時に上方に向けて空気を送り出すことが難しくなる可能性があるからである。 Specifically, the flat tube 21 is inclined toward the outlet 11 toward the lower side by an inclination angle θa with respect to the horizontal direction HD. The inclination angle θa is preferably smaller than 45 degrees. This is because, for example, water droplets condensed by the flat tube 21 can be prevented from falling during the cooling operation, and the water droplets can be easily discharged along the corrugated fins 25. The inclination angle θa is more preferably 5 degrees or more and 10 degrees or less. For example, water droplets condensed by the flat tube 21 can be effectively discharged along the corrugated fins 25 during cooling operation. Further, if the inclination angle θa is too large, for example, it may be difficult to send air upward during cooling operation.
　ここで、実施形態１では、扁平管２１の幅方向ＷＤと、第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒの延びる方向（具体的には、所定方向ＰＤ）とは、実質的に直交している。従って、第１方向Ｄ１（図３）から第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒを見たときに、第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒは、鉛直方向ＶＤに対して下方に向けて吹出口１１側に傾斜している。具体的には、第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒは、鉛直方向ＶＤに対して、傾斜角θｂだけ下方に向けて吹出口１１側に傾斜している。傾斜角θｂは傾斜角θａと略同一である。 Here, in Embodiment 1, the width direction WD of the flat tube 21 and the direction in which the first header tube 23L and the second header tube 23R extend (specifically, the predetermined direction PD) are substantially orthogonal to each other. Yes. Accordingly, when the first header pipe 23L and the second header pipe 23R are viewed from the first direction D1 (FIG. 3), the first header pipe 23L and the second header pipe 23R are directed downward with respect to the vertical direction VD. And inclined toward the outlet 11. Specifically, the first header pipe 23L and the second header pipe 23R are inclined toward the air outlet 11 toward the lower side by the inclination angle θb with respect to the vertical direction VD. The inclination angle θb is substantially the same as the inclination angle θa.
　引き続き図２を参照して、パネル３と扁平管２１との関係を説明する。図２に示すように、パネル３は、暖房運転時の姿勢をとっている。つまり、パネル３の上端部が吹出口１１に近い側に位置するとともに、パネル３の下端部が吹出口１１から遠い側に位置するように、パネル３は鉛直方向ＶＤに対して傾斜している。従って、暖房運転時に、パネル３は、第１熱交換部７を通って吹出口１１から送り出された空気Ａ２をパネル３の下方に送り出す。つまり、パネル３は、第１熱交換部７から送り出された空気Ａ２の送風方向を変化させて、送風方向の変化した空気Ａ３をパネル３の下方に送り出す。 Next, the relationship between the panel 3 and the flat tube 21 will be described with reference to FIG. As shown in FIG. 2, the panel 3 takes the attitude | position at the time of heating operation. That is, the panel 3 is inclined with respect to the vertical direction VD so that the upper end portion of the panel 3 is located on the side closer to the air outlet 11 and the lower end portion of the panel 3 is located on the side farther from the air outlet 11. . Therefore, at the time of heating operation, the panel 3 sends out the air A2 sent out from the blower outlet 11 through the first heat exchange unit 7 to the lower side of the panel 3. That is, the panel 3 changes the blowing direction of the air A2 sent out from the first heat exchange unit 7 and sends out the air A3 whose blowing direction has changed to the lower side of the panel 3.
　そして、暖房運転時に、扁平管２１及びパネル３を第１方向Ｄ１（図３）から見たときに、扁平管２１の鉛直下方向ＤＤに対する傾斜角θ１は、パネル３の鉛直下方向ＤＤに対する傾斜角θ２よりも大きい。従って、第１熱交換部７から送り出された空気Ａ２を効果的にパネル３に当てることができる。その結果、暖房運転時に、パネル３によって、空気をパネル３の下方に効果的に送り出すことができる。傾斜角θ１は、例えば、暖房運転時にパネル３の取り得る最大角度である。なお、傾斜角θ１が傾斜角θ２よりも小さいと、パネル３に当たる空気量が少なくなり、下方に送り出すことの可能な空気量が減少する可能性がある。また、傾斜角θ１が大きいため、扁平管２１による空気Ａ１に対する流路抵抗を低減できる。 When the flat tube 21 and the panel 3 are viewed from the first direction D1 (FIG. 3) during the heating operation, the inclination angle θ1 of the flat tube 21 with respect to the vertical downward direction DD is the inclination of the panel 3 with respect to the vertical downward direction DD. It is larger than the angle θ2. Therefore, the air A2 sent out from the first heat exchange unit 7 can be effectively applied to the panel 3. As a result, air can be effectively sent out below the panel 3 by the panel 3 during the heating operation. The inclination angle θ1 is, for example, the maximum angle that the panel 3 can take during heating operation. If the inclination angle θ1 is smaller than the inclination angle θ2, the amount of air that strikes the panel 3 decreases, and the amount of air that can be sent downward may decrease. Further, since the inclination angle θ1 is large, the flow path resistance against the air A1 by the flat tube 21 can be reduced.
　また、傾斜角θ２が鋭角であるため、第１熱交換部７から送り出された空気Ａ２を更に効果的にパネル３に当てることができる。その結果、暖房運転時に、パネル３は、空気Ａ３をパネル３の下方に更に効果的に送り出すことができる。 Further, since the inclination angle θ2 is an acute angle, the air A2 sent out from the first heat exchange unit 7 can be applied to the panel 3 more effectively. As a result, at the time of heating operation, the panel 3 can more effectively send out the air A3 below the panel 3.
　次に、図４を参照して、冷房運転時のパネル３を説明する。図４は、空気調和機１００の冷房時の状態を示す模式的断面図である。図４に示すように、パネル３は、冷房運転時の姿勢をとっている。つまり、パネル３の上端部が吹出口１１から遠い側に位置するとともに、パネル３の下端部が吹出口１１に近い側に位置するように、パネル３は鉛直方向ＶＤに対して傾斜している。従って、冷房運転時に、パネル３は、第１熱交換部７を通って吹出口１１から送り出された空気Ａ２をパネル３の上方に送り出す。つまり、パネル３は、第１熱交換部７から送り出された空気Ａ２の送風方向を変化させて、送風方向の変化した空気Ａ４をパネル３の上方に送り出す。 Next, the panel 3 during cooling operation will be described with reference to FIG. FIG. 4 is a schematic cross-sectional view showing a state of the air conditioner 100 during cooling. As shown in FIG. 4, the panel 3 takes a posture during cooling operation. That is, the panel 3 is inclined with respect to the vertical direction VD so that the upper end of the panel 3 is located on the side far from the air outlet 11 and the lower end of the panel 3 is located on the side closer to the air outlet 11. . Therefore, at the time of cooling operation, the panel 3 sends the air A2 sent from the blower outlet 11 through the first heat exchange unit 7 to the upper side of the panel 3. That is, the panel 3 changes the blowing direction of the air A <b> 2 sent out from the first heat exchange unit 7 and sends out the air A <b> 4 whose blowing direction has changed to the upper side of the panel 3.
　従って、実施形態１によれば、扁平管２１が水平方向ＨＤに対して下方に向けて吹出口１１側に傾斜しているにも拘わらず、冷房運転時に冷えた空気Ａ４をパネル３の上方に送り出すことができる。つまり、冷房運転時と暖房運転時（図２）との双方において、運転状態に応じた適切な方向に空気を送り出すことができる。 Therefore, according to the first embodiment, the air A4 cooled during the cooling operation is placed above the panel 3 even though the flat tube 21 is inclined downward toward the blowout outlet 11 with respect to the horizontal direction HD. Can be sent out. That is, air can be sent out in an appropriate direction according to the operating state both during the cooling operation and during the heating operation (FIG. 2).
　特に、冷房運転時に、パネル３を第１方向Ｄ１（図３）から見たときに、パネル３の鉛直上方向ＵＤに対する傾斜角θ３は、鋭角である。従って、第１熱交換部７から送り出された空気Ａ２を効果的にパネル３に当てることができる。その結果、冷房運転時に、パネル３によって、空気Ａ４をパネル３の上方に効果的に送り出すことができる。 Particularly, when the panel 3 is viewed from the first direction D1 (FIG. 3) during the cooling operation, the inclination angle θ3 of the panel 3 with respect to the vertical upward direction UD is an acute angle. Therefore, the air A2 sent out from the first heat exchange unit 7 can be effectively applied to the panel 3. As a result, the air A4 can be effectively sent out above the panel 3 by the panel 3 during the cooling operation.
　（実施形態２）
　図５及び図６を参照して、本発明の実施形態２に係る空気調和機１００Ａを説明する。実施形態２に係る空気調和機１００Ａが第１熱交換部７に加えて第２熱交換部３１をさらに備える点で、実施形態２は実施形態１と主に異なる。以下、実施形態２が実施形態１と異なる点を主に説明する。 (Embodiment 2)
With reference to FIG.5 and FIG.6, the air conditioner 100A which concerns on Embodiment 2 of this invention is demonstrated. The second embodiment is mainly different from the first embodiment in that the air conditioner 100A according to the second embodiment further includes a second heat exchange unit 31 in addition to the first heat exchange unit 7. Hereinafter, the points of the second embodiment different from the first embodiment will be mainly described.
　図５は、空気調和機１００Ａを示す模式的断面図である。図５に示すように、空気調和機１００Ａは、図２を参照して説明した空気調和機１００の構成に加えて、第２熱交換部３１をさらに備える。第２熱交換部３１は熱交換を行う。具体的には、第２熱交換部３１は、空気と冷媒との間で熱エネルギーを交換する。実施形態２では、第２熱交換部３１はフィンアンドチューブ型熱交換器である。 FIG. 5 is a schematic cross-sectional view showing the air conditioner 100A. As shown in FIG. 5, the air conditioner 100 </ b> A further includes a second heat exchange unit 31 in addition to the configuration of the air conditioner 100 described with reference to FIG. 2. The second heat exchange unit 31 performs heat exchange. Specifically, the second heat exchange unit 31 exchanges thermal energy between air and the refrigerant. In Embodiment 2, the 2nd heat exchange part 31 is a fin and tube type heat exchanger.
　第２熱交換部３１は筐体１に収容される。第２熱交換部３１は、ファン５と第１熱交換部７との間に配置される。具体的には、第２熱交換部３１は、ファン５よりも、空気の流れの下流に位置する。そして、第１熱交換部７は、第２熱交換部３１よりも、空気の流れの下流に位置する。 The second heat exchange unit 31 is accommodated in the housing 1. The second heat exchange unit 31 is disposed between the fan 5 and the first heat exchange unit 7. Specifically, the second heat exchange unit 31 is located downstream of the air flow with respect to the fan 5. And the 1st heat exchange part 7 is located in the downstream of the flow of air rather than the 2nd heat exchange part 31. FIG.
　ファン５は、吸入口９から吸い込んだ空気Ａ１を、第２熱交換部３１を通して第１熱交換部７に向けて送り出す。従って、空気Ａ１は、第２熱交換部３１を通過して、第１熱交換部７に流入する。そして、第１熱交換部７は、第２熱交換部３１を通過した空気Ａ１を整流して、整流後の空気Ａ２を吹出口１１から筐体１の外部に送り出す。 The fan 5 sends out the air A1 sucked from the suction port 9 toward the first heat exchange unit 7 through the second heat exchange unit 31. Therefore, the air A <b> 1 passes through the second heat exchange unit 31 and flows into the first heat exchange unit 7. And the 1st heat exchange part 7 rectifies the air A1 which passed the 2nd heat exchange part 31, and sends out the rectified air A2 to the exterior of the housing | casing 1 from the blower outlet 11. FIG.
　実施形態２によれば、第１熱交換部７が第２熱交換部３１よりも空気の流れの下流に位置するため、第１熱交換部７が第２熱交換部３１よりも空気の流れの上流に位置する場合と比較して、整流後の空気Ａ２の流れが変化することを抑制しつつ、空気Ａ２を吹出口１１に向けて送り出すことができる。なお、第１熱交換部７が第２熱交換部３１よりも空気の流れの上流に位置する場合は、整流後の空気Ａ２の流れが、第２熱交換部３１によって変化する可能性があり得る。 According to the second embodiment, since the first heat exchange unit 7 is located downstream of the second heat exchange unit 31 in the air flow, the first heat exchange unit 7 is in the air flow more than the second heat exchange unit 31. Compared with the case where it is located upstream, air A2 can be sent out toward the blower outlet 11, suppressing the change of the flow of air A2 after rectification. In addition, when the 1st heat exchange part 7 is located in the upstream of the flow of air rather than the 2nd heat exchange part 31, the flow of the air A2 after rectification may change with the 2nd heat exchange part 31. obtain.
　また、実施形態２によれば、空気調和機１００Ａは２つの熱交換部（第１熱交換部７及び第２熱交換部３１）を備えているため、１つの熱交換部を備える場合と比較して、効果的に熱交換を行うことができる。 In addition, according to the second embodiment, the air conditioner 100A includes two heat exchange units (the first heat exchange unit 7 and the second heat exchange unit 31), and therefore, compared with a case where one heat exchange unit is provided. Thus, heat exchange can be performed effectively.
　次に、図５及び図６を参照して、第２熱交換部３１を詳細に説明する。図６は、第２熱交換部３１を示す正面図である。図５及び図６に示すように、第２熱交換部３１は、管３３と、平板状の複数のフィン３５とを含む。複数のフィン３５の各々は、第３方向Ｄ３に沿って延びており、第４方向Ｄ４に沿って並んでいる。第４方向Ｄ４は、第３方向Ｄ３に直交する。第３方向Ｄ３と第１方向Ｄ１（図３）とは、互いに実質的に直交する。第３方向Ｄ３と第２方向Ｄ２（図３）とは、互いに実質的に平行である。第４方向Ｄ４と第１方向Ｄ１（図３）とは、互いに実質的に平行である。従って、実施形態２では、第４方向Ｄ４は、水平方向と実質的に平行である。フィン３５を第４方向Ｄ４（図６）から見たときに、フィン３５は略矩形状である。 Next, the second heat exchange unit 31 will be described in detail with reference to FIGS. 5 and 6. FIG. 6 is a front view showing the second heat exchange unit 31. As shown in FIGS. 5 and 6, the second heat exchange unit 31 includes a tube 33 and a plurality of flat fins 35. Each of the plurality of fins 35 extends along the third direction D3 and is aligned along the fourth direction D4. The fourth direction D4 is orthogonal to the third direction D3. The third direction D3 and the first direction D1 (FIG. 3) are substantially orthogonal to each other. The third direction D3 and the second direction D2 (FIG. 3) are substantially parallel to each other. The fourth direction D4 and the first direction D1 (FIG. 3) are substantially parallel to each other. Therefore, in the second embodiment, the fourth direction D4 is substantially parallel to the horizontal direction. When the fin 35 is viewed from the fourth direction D4 (FIG. 6), the fin 35 has a substantially rectangular shape.
　管３３は、複数のフィンを第４方向Ｄ４に貫通し、蛇行している。管３３は、冷媒流路３３ａを有する。冷媒は冷媒流路３３ａを流れる。冷媒流路３３ａは、管３３に沿って蛇行している。管３３は、冷媒流入部３３ｂと、冷媒流出部３３ｃとを有する。冷媒流入部３３ｂから流入した冷媒は、冷媒流路３３ａを流れて、冷媒流出部３３ｃから流出する。実施形態２では、管３３の冷媒流出部３３ｃは、第１熱交換部７の第１ヘッダ管２３Ｌの冷媒流入部２３ａ（図３）に接続される。なお、図６は正面図であるため、冷媒流路３３ａは図６には表れていない。 The pipe 33 penetrates the plurality of fins in the fourth direction D4 and meanders. The pipe 33 has a refrigerant flow path 33a. The refrigerant flows through the refrigerant flow path 33a. The refrigerant flow path 33 a meanders along the pipe 33. The pipe 33 has a refrigerant inflow portion 33b and a refrigerant outflow portion 33c. The refrigerant flowing in from the refrigerant inflow portion 33b flows through the refrigerant flow path 33a and flows out from the refrigerant outflow portion 33c. In the second embodiment, the refrigerant outflow portion 33 c of the pipe 33 is connected to the refrigerant inflow portion 23 a (FIG. 3) of the first header pipe 23 </ b> L of the first heat exchange unit 7. Since FIG. 6 is a front view, the refrigerant flow path 33a does not appear in FIG.
　引き続き図５を参照して、第１熱交換部７及び第２熱交換部３１を説明する。図５に示すように、第１熱交換部７と第２熱交換部３１とは、互いに対向して配置される。第１熱交換部７と第２熱交換部３１とは、互いに実質的に平行になるように近接して配置される。従って、実施形態２によれば、例えば、冷房運転時に、扁平管２１によって凝縮された水滴が、表面張力によってフィン３５に移動するため、水滴をフィン３５によって円滑に排出できる。ここで、第１熱交換部７と第２熱交換部３１との距離、つまり、扁平管２１とフィン３５との距離は、表面張力によって、扁平管２１に付着した水滴がフィン３５に移動し得ることの可能な距離である。また、扁平管２１とフィン３５とが接触していないため、扁平管２１とフィン３５との接触に起因する音の発生を抑制できる。なお、扁平管２１とフィン３５とが接触していてもよい。 The first heat exchange unit 7 and the second heat exchange unit 31 will be described with reference to FIG. As shown in FIG. 5, the 1st heat exchange part 7 and the 2nd heat exchange part 31 are arrange | positioned facing each other. The first heat exchange unit 7 and the second heat exchange unit 31 are arranged close to each other so as to be substantially parallel to each other. Therefore, according to the second embodiment, for example, during the cooling operation, the water droplets condensed by the flat tube 21 move to the fins 35 due to the surface tension, so that the water droplets can be smoothly discharged by the fins 35. Here, the distance between the first heat exchange unit 7 and the second heat exchange unit 31, that is, the distance between the flat tube 21 and the fin 35, is that water droplets attached to the flat tube 21 move to the fin 35 due to surface tension. The distance that can be obtained. Further, since the flat tube 21 and the fins 35 are not in contact with each other, it is possible to suppress the generation of sound due to the contact between the flat tube 21 and the fins 35. The flat tube 21 and the fins 35 may be in contact with each other.
　また、第１熱交換部７と第２熱交換部３１とが互いに実質的に平行になるように近接して配置されるため、第１熱交換部７と第２熱交換部３１とを筐体１に固定する作業が容易である。さらに、第１熱交換部７と第２熱交換部３１との間に無駄な空間が生じることを抑制できて、空気調和機１００Ａの小型化を実現できる。 Further, since the first heat exchange unit 7 and the second heat exchange unit 31 are arranged close to each other so as to be substantially parallel to each other, the first heat exchange unit 7 and the second heat exchange unit 31 are connected to the housing. The work of fixing to the body 1 is easy. Furthermore, it is possible to suppress the generation of a useless space between the first heat exchange unit 7 and the second heat exchange unit 31, and it is possible to reduce the size of the air conditioner 100A.
　さらに、実施形態２では、扁平管２１とフィン３５とを第１方向Ｄ１（図３）から見たときに、扁平管２１の長手方向の幅Ｗ１は、フィン３５の短手方向の幅Ｗ２よりも大きい。従って、幅Ｗ２を小さくして、フィン３５による空気Ａ１に対する流路抵抗を低減しつつ、幅Ｗ１を大きくして、扁平管２１による空気Ａ１に対する整流作用を向上できる。 Furthermore, in Embodiment 2, when the flat tube 21 and the fin 35 are viewed from the first direction D1 (FIG. 3), the width W1 in the longitudinal direction of the flat tube 21 is greater than the width W2 in the short direction of the fin 35. Is also big. Therefore, the width W2 can be reduced and the flow resistance against the air A1 by the fins 35 can be reduced, and the width W1 can be increased to improve the rectification action on the air A1 by the flat tube 21.
　（実施形態３）
　図７を参照して、本発明の実施形態３に係る空気調和機１００Ｂを説明する。実施形態３に係る空気調和機１００Ｂの扁平管２１が第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒに対して傾斜している点で、実施形態３は実施形態１と主に異なる。以下、実施形態３が実施形態１と異なる点を主に説明する。 (Embodiment 3)
With reference to FIG. 7, the air conditioner 100B which concerns on Embodiment 3 of this invention is demonstrated. The third embodiment is mainly different from the first embodiment in that the flat tube 21 of the air conditioner 100B according to the third embodiment is inclined with respect to the first header tube 23L and the second header tube 23R. Hereinafter, the points of the third embodiment different from the first embodiment will be mainly described.
　図７は、空気調和機１００Ｂを示す模式的断面図である。図７に示すように、第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒは、所定方向ＰＤに沿って延びている。実施形態３では、所定方向ＰＤは、第１方向Ｄ１に直交し、鉛直方向ＶＤと実質的に平行である。そして、第１方向Ｄ１（図３）から扁平管２１を見たときに、扁平管２１は、第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒに対して傾斜している。具体的には、実施形態１と同様に、扁平管２１は、水平方向ＨＤに対して傾斜している。更に具体的には、扁平管２１は、水平方向ＨＤに対して下方に向けて吹出口１１側に傾斜している。更に具体的には、扁平管２１は、水平方向ＨＤに対して、傾斜角θａだけ下方に向けて吹出口１１側に傾斜している。 FIG. 7 is a schematic cross-sectional view showing the air conditioner 100B. As shown in FIG. 7, the first header pipe 23L and the second header pipe 23R extend along the predetermined direction PD. In the third embodiment, the predetermined direction PD is orthogonal to the first direction D1 and substantially parallel to the vertical direction VD. When the flat tube 21 is viewed from the first direction D1 (FIG. 3), the flat tube 21 is inclined with respect to the first header tube 23L and the second header tube 23R. Specifically, as in the first embodiment, the flat tube 21 is inclined with respect to the horizontal direction HD. More specifically, the flat tube 21 is inclined toward the outlet 11 toward the lower side with respect to the horizontal direction HD. More specifically, the flat tube 21 is inclined to the outlet 11 side downward by an inclination angle θa with respect to the horizontal direction HD.
　実施形態３によれば、第１ヘッダ管２３Ｌ及び第２ヘッダ管２３Ｒが鉛直方向ＶＤ（所定方向ＰＤ）に沿って延びつつ、扁平管２１だけが傾斜している。従って、第１熱交換部７の筐体１への設置作業を容易にしつつ、扁平管２１によって空気Ａ１を整流できる。 According to the third embodiment, only the flat tube 21 is inclined while the first header tube 23L and the second header tube 23R extend along the vertical direction VD (predetermined direction PD). Therefore, the air A1 can be rectified by the flat tube 21 while facilitating the installation work of the first heat exchange unit 7 on the housing 1.
　なお、空気調和機１００Ｂは図５に示す第２熱交換部３１を備えていてもよい。この場合、フィン３５が鉛直方向ＶＤに沿って延びるように、第２熱交換部３１が筐体１に設置される。 In addition, the air conditioner 100B may include the second heat exchange unit 31 illustrated in FIG. In this case, the second heat exchange unit 31 is installed in the housing 1 such that the fins 35 extend along the vertical direction VD.

　（１）図２、図５、及び図７を参照して説明した実施形態１～実施形態３において、扁平管２１は、水平方向ＨＤに対して上方に向けて吹出口１１側に傾斜していてもよい。従って、水平方向ＨＤに対して上方に向けて吹出口１１側に傾斜した方向に、空気Ａ２を送り出すことができる。その結果、扁平管２１の傾斜は、冷たい空気を室内に送り出す冷房運転時の空気調和機１００、１００Ａ、１００Ｂに好適である。さらに、図４に示すような冷房運転時の状態では、複数の扁平管２１によって整流された空気Ａ２の一部は、パネル３によって、パネル３の上方に向けて送り出される。従って、室内を更に効果的に冷やすことができる。 (1) In the first to third embodiments described with reference to FIG. 2, FIG. 5, and FIG. 7, the flat tube 21 is inclined toward the outlet 11 toward the upper side with respect to the horizontal direction HD. May be. Therefore, the air A2 can be sent out in a direction inclined upward toward the air outlet 11 with respect to the horizontal direction HD. As a result, the inclination of the flat tube 21 is suitable for the air conditioners 100, 100 </ b> A, 100 </ b> B during the cooling operation for sending cold air into the room. Further, in the state during the cooling operation as shown in FIG. 4, a part of the air A <b> 2 rectified by the plurality of flat tubes 21 is sent out upward of the panel 3 by the panel 3. Therefore, the room can be cooled more effectively.
　具体的には、扁平管２１は、水平方向ＨＤに対して、傾斜角θａだけ上方に向けて吹出口１１側に傾斜していてもよい。傾斜角θａは、４５度よりも小さいことが好ましい。傾斜角θａは、５度以上１０度以下であることが更に好ましい。 Specifically, the flat tube 21 may be inclined toward the outlet 11 side upward by an inclination angle θa with respect to the horizontal direction HD. The inclination angle θa is preferably smaller than 45 degrees. More preferably, the inclination angle θa is not less than 5 degrees and not more than 10 degrees.
　（２）図２、図５、及び図７を参照して説明した実施形態１～実施形態３において、パネル３は、湾曲することなく、平板状であってもよい。また、パネル３は、筐体１から離れる方向に向かって凸状に湾曲していてもよい。 (2) In the first to third embodiments described with reference to FIGS. 2, 5, and 7, the panel 3 may be flat without being curved. The panel 3 may be curved in a convex shape in a direction away from the housing 1.
　また、扁平管２１を正面視したときに、扁平管２１が水平方向に対して傾斜していてもよい。この場合、扁平管２１に付着した水滴を排出するための排水口が、扁平管２１の傾斜している下方側に配置されることが好ましい。水滴が排水口に向かって流れ易いからである。「正面視」は、図３に示すように、第１方向Ｄ１と第２方向Ｄ２との双方に直交する方向から扁平管２１を見ることを示す。 Further, when the flat tube 21 is viewed from the front, the flat tube 21 may be inclined with respect to the horizontal direction. In this case, it is preferable that a drain outlet for discharging water droplets attached to the flat tube 21 is disposed on the inclined lower side of the flat tube 21. This is because water droplets easily flow toward the drain outlet. “Front view” indicates that the flat tube 21 is viewed from a direction orthogonal to both the first direction D1 and the second direction D2, as shown in FIG.
　（３）図２、図５、及び図７を参照して説明した実施形態１～実施形態３において、第１熱交換部７は、ダウンフロータイプのパラレルフロー型熱交換器であってもよい。この場合は、例えば、複数のコルゲートフィン２５によって、垂直方向（具体的には、上下方向）に空気を整流できる。なお、例えば、複数の扁平管２１によって、水平方向（具体的には、左右方向）に空気を整流することも可能である。 (3) In the first to third embodiments described with reference to FIG. 2, FIG. 5, and FIG. 7, the first heat exchange unit 7 may be a down flow type parallel flow heat exchanger. . In this case, for example, the air can be rectified in the vertical direction (specifically, the vertical direction) by the plurality of corrugated fins 25. For example, air can be rectified in the horizontal direction (specifically, the left-right direction) by the plurality of flat tubes 21.
　（４）図５を参照して説明した実施形態２において、第１熱交換部７と第２熱交換部３１とは、略平行に配置されていなくてもよい。第２熱交換部３１は、第１熱交換部７と同様のパラレルフロー型熱交換器（例えば、サイドフロータイプのパラレルフロー型熱交換器）であってもよい。第１熱交換部７は、第２熱交換部３１よりも、空気の流れの上流に位置していてもよい。 (4) In the second embodiment described with reference to FIG. 5, the first heat exchange unit 7 and the second heat exchange unit 31 may not be arranged substantially in parallel.
