また、ケーシング 2内には、ケーシング 2の平面視において 2つの送風ファン 3の配 列方向（すなわち、ケーシング 2の長手方向）に直交する側に、送風ファン 3の配列方 向（すなわち、ケーシング 2の長手方向）に延びる 2つの熱交換器 5が、送風ファン 3 を挟むように配置されている。より具体的には、各熱交翻5は、図 4に示されるよう に、積層型熱交 力もなり、上下方向に延びる伝熱管 51とフィン 52とが交互に積 層し、かつ、伝熱管 51の上端と下端とがそれぞれ上部ヘッダー管 53と下部ヘッダー 管 54とによって接続されることにより構成されている。伝熱管 51は偏平管であり、また 、フィン 52はアルミ製のコルゲートフィンである。ここで、図 4は、上下方向に延びる伝 熱管 51を有する積層型熱交換器を示す図である。そして、各熱交換器 5は、ケーシ ング 2を側面視 (すなわち、ケーシング 2を長手方向から見た際）において傾斜して配 置されている。より具体的には、各熱交翻5は、送風ファン 3に対して上部が下部よ りも遠い側に傾斜して配置されている。また、ドレンパン 2bの各熱交^^ 5の下部に 対向する位置には、ドレン受け部 26cが形成されている。 Further, in the casing 2, in the plan view of the casing 2, the arrangement direction of the blower fans 3 (that is, the casing 2) is arranged on the side perpendicular to the arrangement direction of the two blower fans 3 (that is, the longitudinal direction of the casing 2). The two heat exchangers 5 extending in the longitudinal direction) are arranged so as to sandwich the blower fan 3. More specifically, as shown in FIG. 4, each heat exchanger 5 also has a stacked heat exchange force, and heat transfer tubes 51 and fins 52 extending in the vertical direction are alternately stacked, and the heat transfer tubes The upper end and the lower end of 51 are connected by an upper header pipe 53 and a lower header pipe 54, respectively. The heat transfer tube 51 is a flat tube, and The fin 52 is an aluminum corrugated fin. Here, FIG. 4 is a view showing a stacked heat exchanger having heat transfer tubes 51 extending in the vertical direction. Each of the heat exchangers 5 is disposed so as to be inclined when the casing 2 is viewed from the side (that is, when the casing 2 is viewed from the longitudinal direction). More specifically, each heat exchanger 5 is arranged such that the upper part of the heat exchanger 5 is inclined to the side farther from the lower part than the lower part. Further, a drain receiving portion 26c is formed at a position facing the lower part of each heat exchanger 5 of the drain pan 2b.
[0026] そして、この空気調和装置 1のケーシング 2内には、吸入開口 26aから、送風ファン 3及び熱交換器 5を通過して下面吹出開口 26bに至る空気流路 Sが形成されている 。ここで、空気流路 Sのうち熱交換器 5よりも上流側の部分を空気流路 S1と熱交換器 5よりも下流側の部分を空気流路 S2とすると、側板 22、 24に形成された側面吹出開 口用切取線 22b、 24bは側板 22、 24のうち熱交換器 5の下側の空気流路 S2に面す る部分に形成されており、また、側板 23、 25に形成された補助連通開口用切取線 2 3b、 25bは側板 23、 25のうち熱交換器 5の下側の空気流路 S2に面する略直角三角 形の部分に形成されている。このため、側板 22、 24を側面吹出開口用切取線 22b、 24bに沿って切り取ることによって形成される側面吹出開口 22a、 24aは、下面吹出 開口 26bと同様に、熱交翻 5を通過した後の空気を吹き出すことができる。また、側 板 23、 25を補助連通開口用切取線 23b、 25bに沿って切り取ることによって形成さ れる補助連通開口 23a、 25aは、下面吹出開口 26bと同様に、熱交 5を通過した 後の空気を吹き出すことができる。 [0026] In the casing 2 of the air conditioner 1, an air flow path S is formed from the suction opening 26a through the blower fan 3 and the heat exchanger 5 to the lower surface blowout opening 26b. Here, if the upstream side of the heat exchanger 5 in the air flow path S is the air flow path S1 and the downstream side of the heat exchanger 5 is the air flow path S2, it is formed on the side plates 22 and 24. The side outlet opening cut lines 22b and 24b are formed on the side plates 22 and 24 facing the lower air flow path S2 of the heat exchanger 5 and formed on the side plates 23 and 25. The auxiliary communication opening cut lines 23b and 25b are formed on the side plates 23 and 25 in a substantially right triangular portion facing the air flow path S2 on the lower side of the heat exchanger 5. For this reason, the side blowout openings 22a and 24a formed by cutting the side plates 22 and 24 along the cutout lines 22b and 24b for the side blowout openings are the same as the bottom blowout openings 26b. Air can be blown out. Further, the auxiliary communication openings 23a and 25a formed by cutting the side plates 23 and 25 along the auxiliary communication opening cut lines 23b and 25b are the air after passing through the heat exchanger 5 in the same manner as the lower surface blowout openings 26b.

[0027] (2)天井埋込型の形態にする場合 [0027] (2) In the case of an embedded ceiling type
< 2方向に吹き出す天井埋込型の空気調和装置の形態にする場合 > 上述の天井設置型の空気調和装置 1を 2方向に吹き出すタイプの天井埋込型の空 気調和装置の形態にする場合には、図 5及び図 6に示されるように、天井埋込用化 粧パネル 11をケーシング 2の下面を覆うように装着する。ここで、図 5は、天井設置型 の空気調和装置 1の外観斜視図であって、 2方向に吹き出す天井埋込型の形態にし た状態を示す図である。図 6は、天井設置型の空気調和装置 1の概略側面断面図で あって、図 5の A— A断面図である。  <When using a ceiling-embedded air conditioner that blows in two directions> When using the ceiling-mounted air conditioner 1 that blows in two directions as a ceiling-embedded air conditioner 5 and FIG. 6, the ceiling-embedded decorative panel 11 is mounted so as to cover the lower surface of the casing 2. Here, FIG. 5 is an external perspective view of the ceiling-mounted air conditioner 1 and shows a state in which the ceiling embedded type is blown out in two directions. FIG. 6 is a schematic side cross-sectional view of the ceiling-mounted air conditioner 1, and is a cross-sectional view taken along the line AA in FIG.
天井埋込用化粧パネル 11は、その平面視において、ケーシング 2 (すなわち、天板 21ゃドレンパン 2b)よりも大きな略矩形形状の板状部材であり、ケーシング 2の 2つの 吸入開口 26aに連通する吸入口 11aと、ケーシング 2の各下面吹出開口 26bに連通 する 2つの下面吹出口 l ibとが形成されている。下面吹出口 l ibは、ケーシング 2の 平面視にお！ヽて天井埋込用化粧パネル 11の長手方向に直交する方向の両端側 ( すなわち、側板 22、 24側）の位置に配置されており、天井埋込用化粧パネル 11の 長手方向に沿って水平に延びる細長い略矩形形状の開口である。吸入口 11aは、 下面吹出口 l ibによって両側から挟まれる位置に配置されている。また、吸入口 11a には、フィルタ 11cが配置されている。 The ceiling-embedded decorative panel 11 has a casing 2 (that is, a top plate) in the plan view. 21 is a plate-like member having a substantially rectangular shape larger than the drain pan 2b), and has two suction openings 11a communicating with the two suction openings 26a of the casing 2 and two lower face outlets communicating with the respective lower face outlet openings 26b of the casing 2. l ib is formed. The bottom outlet l ib is a plan view of the casing 2! It is placed at both ends in the direction orthogonal to the longitudinal direction of the decorative panel 11 for embedding the ceiling (that is, on the side plates 22 and 24 side), and horizontally along the longitudinal direction of the decorative panel 11 for embedding the ceiling It is an elongate substantially rectangular-shaped opening extended in the direction. The suction port 11a is arranged at a position sandwiched from both sides by the lower surface outlet l ib. Further, a filter 11c is disposed in the suction port 11a.

本実施形態の天井設置型の空気調和装置 1には、以下のような特徴がある。 The ceiling-mounted air conditioner 1 of the present embodiment has the following characteristics.
(A) (A)
本実施形態の天井設置型の空気調和装置 1では、ケーシング 2に第 1化粧パネル としての天井埋込用化粧パネル 11、 13又は第 2ィ匕粧パネルとしての天井吊下用化 粧パネル 15、 17のいずれかを装着することにより、空気を本体下面 (具体的には、吸 入口 l la、 13a)から吸入して本体下面（具体的には、下面吹出口 l lb、 12a、 13b) 力も吹き出す天井埋込型の形態又は空気を本体下面 (具体的には、吸入口 61a、 7 la)力ら吸人して本体佃 J面（具体的に ίま、佃 J面吹出口 62a、 64a, 72a, 73a, 74a, 7 5a)力 吹き出す天井吊下型の形態の両方に対応することが可能である。 In the ceiling-mounted air conditioner 1 of the present embodiment, the casing 2 has a ceiling-embedded decorative panel 11, 13 as a first decorative panel or a ceiling-suspended decorative panel as a second decorative panel. By installing either of the decorative panels 15 and 17, air is sucked from the lower surface of the main body (specifically, the inlets l la and 13a), and the lower surface of the main body (specifically, the lower outlets l lb and 12a 13b) A ceiling-embedded form that blows out force or air is sucked from the bottom surface of the main body (specifically, the inlet 61a, 7 la), and the main body 佃 J surface (specifically ί or ί J surface blowing) Outlet 62a, 64a, 72a, 73a, 74a, 75a) Force It is possible to deal with both types of ceiling suspended type that blows out.
[0041] また、側面吹出開口 22a、 24aは、ケーシング 2の側面 (具体的には、側板 22、 24) の一部を切り取ることによって形成されるため、ケーシング 2に天井吊下用化粧パネ ル 15、 17を装着する際に、容易に側面吹出開口 22a、 24aを形成することができる。 し力も、 2方向に吹き出す天井埋込型の形態にした状態において、側板 22、 24を 側面吹出開口用切取線 22b、 24bに沿って切り取ることによって側面吹出開口 22a、 24aを形成するとともに、側面吹出開口 22a、 24aをダクト接続することで、ケーシング 2を設置する位置力 離れた別の位置力 空気を吹き出すように構成することも可能 である。 [0041] Further, since the side outlets 22a and 24a are formed by cutting out a part of the side surface of the casing 2 (specifically, the side plates 22 and 24), the decorative panel for hanging the ceiling in the casing 2 is formed. When the 15 and 17 are attached, the side outlets 22a and 24a can be easily formed. In the state of the ceiling embedded type that blows out in two directions, the side plates 22 and 24 are cut along the side blowout opening cut lines 22b and 24b to form the side blowout openings 22a and 24a, and the side blowout By connecting the openings 22a and 24a with ducts, it is possible to blow out another position force air away from the position force where the casing 2 is installed.

本実施形態の天井設置型の空気調和装置 1では、天井埋込型の形態にする際に 使用される第 1吹出開口としての下面吹出開口 26bと、天井吊下型の形態にする際 に使用される第 2吹出開口としての側面吹出開口 22a、 24aとが、ケーシング 2の下 面（具体的には、ドレンパン 2b)の 4辺のうち 1対の対辺に沿うように形成されているた め、天井埋込型の形態及び天井吊下型の形態のいずれの場合においても、少なくと もケーシング 2内から 2方向に空気を吹き出す構成が得られるようになって 、る。 しかも、この空気調和装置 1では、複数のケーシング 2を側面吹出開口 22a、 24aが 形成される側面 (具体的には、側板 22、 24)に直交する側面 (具体的には、側板 23 、 25)同士が対向するように並べて配置する際に、隣り合うケーシング 2に装着される 天井埋込用化粧パネル 11又は天井吊下用化粧パネル 15同士を連結するためのパ ネル案内部材としてのパネル連結ピン 14、 18を備えているため、 2つの空気調和装 置 1を連結させることが可能になり、別の大型の化粧パネル等を準備することなぐ大 容量の空気調和装置を得ることができるようになって 、る。 In the ceiling-mounted air conditioner 1 according to this embodiment, the bottom blowout opening 26b as the first blowout opening used when the ceiling-embedded form is used, and the ceiling-suspended form are used. The side outlet openings 22a and 24a as the second outlet openings are formed so as to be along one pair of opposite sides of the lower side of the casing 2 (specifically, the drain pan 2b). In either case of the ceiling-embedded type or the ceiling-suspended type, a configuration in which air is blown out from the casing 2 in two directions can be obtained. Moreover, in the air conditioner 1, the plurality of casings 2 are provided with side surfaces (specifically, the side plates 23, 25) orthogonal to the side surfaces (specifically, the side plates 22, 24) where the side outlet openings 22a, 24a are formed. ) When laying them side by side so as to face each other, the ceiling-embedded decorative panel 11 or the ceiling-suspended decorative panel 15 attached to the adjacent casing 2 are connected to each other. Panel connection pins 14 and 18 as channel guide members are provided, so it becomes possible to connect two air conditioning devices 1 and a large-capacity air conditioning without preparing another large decorative panel. I can get a device.

本実施形態の天井設置型の空気調和装置 1では、ケーシング 2の側面のうち側面 吹出開口 22a、 24aが形成されない側面 (すなわち、側板 23、 25)には、空気流路 S (具体的には熱交換器 5の下流側の空気流路 S2)に連通する補助連通開口 23a、 2 5aが形成することができるようになっており、補助連通開口 23a、 25aが形成された側 面 (すなわち、側板 23、 25)を覆うように補助吹出チャンバ 12を装着するとともに、補 助吹出チャンバ 12が装着されたケーシング 2に天井埋込用化粧パネル 13を装着す ることによって、本体下面から 2方向だけでなぐ 2方向よりも多くの方向にも空気を吹 き出すような天井埋込型の形態を得たり、又は、補助連通開口 23a、 25aが形成され た側面 (すなわち、側板 23、 25)を覆うように補助吹出チャンバ 16を装着するとともに 、補助吹出チャンバ 16が装着されたケーシング 2に天井吊下用化粧パネル 17を装 着することによって、本体側面から 2方向だけでなぐ 2方向よりも多くの方向にも空気 を吹き出すような天井吊下型の形態を得ることできるようになつている。  In the ceiling-mounted air conditioner 1 of the present embodiment, the air flow path S (specifically, the side surface of the casing 2 where the side outlet openings 22a and 24a are not formed (that is, the side plates 23 and 25) is provided. Auxiliary communication openings 23a, 25a communicating with the air flow path S2) on the downstream side of the heat exchanger 5 can be formed, and the side surfaces where the auxiliary communication openings 23a, 25a are formed (that is, Auxiliary blowout chamber 12 is installed to cover side plates 23, 25), and ceiling-mounted decorative panel 13 is attached to casing 2 fitted with auxiliary blowout chamber 12 in only two directions from the bottom of the main unit. Obtain a ceiling-embedded type that blows air in more directions than two directions, or use the side surfaces with auxiliary communication openings 23a, 25a (i.e., side plates 23, 25). Attaching the auxiliary blowout chamber 16 to cover, Ceiling suspension that blows air in more directions than two directions by attaching the ceiling hanging decorative panel 17 to the casing 2 equipped with the auxiliary blowing chamber 16 in only two directions from the side of the main body. The mold form can be obtained.
[0044] また、補助連通開口 23a、 25aは、ケーシング 2の側面 (具体的には、側板 23、 25) の一部を切り取ることによって形成されるため、ケーシング 2に補助吹出チャンバ 12、 16を装着する際に、容易に補助連通開口 23a、 25aを形成することができる。 [0044] Further, the auxiliary communication openings 23a, 25a are formed by cutting out a part of the side surface of the casing 2 (specifically, the side plates 23, 25), so that the auxiliary blowing chambers 12, 16 are provided in the casing 2. When mounting, the auxiliary communication openings 23a and 25a can be easily formed.

本実施形態の天井設置型の空気調和装置 1では、ケーシング 2内において、回転 軸線 O— Oが上下方向に延びるターボファン力 なる複数の送風ファン 3がケーシン グ 2の平面視において水平方向に並んで配置され、かつ、複数の送風ファン 3の配 列方向に沿って延びる 2つの熱交換器 5がケーシング 2の平面視において複数の送 風ファン 3の配列方向に直交する側に配置されているため、ケーシング 2の高さ方向 寸法のコンパクトィ匕を実現することができる。これにより、上述のような天井埋込型の 形態及び天井吊下型の形態の両方に対応するにあたり、ケーシング 2及びケーシン グ 2内に収容される部品の共通化を図ることができるようになつている。 [0045] (E) In the ceiling-mounted air conditioner 1 of the present embodiment, in the casing 2, a plurality of blower fans 3 having a turbo fan force with the rotation axis O-O extending in the vertical direction are arranged in the horizontal direction in the plan view of the casing 2. And two heat exchangers 5 extending along the arrangement direction of the plurality of blower fans 3 are arranged on the side orthogonal to the arrangement direction of the plurality of blower fans 3 in a plan view of the casing 2. Therefore, the compact size of the casing 2 in the height direction can be realized. As a result, in order to cope with both the above-described ceiling-embedded form and ceiling-suspended form, the parts accommodated in the casing 2 and the casing 2 can be shared. ing. [0045] (E)
本実施形態の天井設置型の空気調和装置 1では、熱交換器 5として積層型熱交換 器を採用しているため、熱交換率が高くコンパクトィ匕が可能であるため、ケーシング 2 の高さ方向寸法のさらなるコンパクトィ匕が実現されている。  In the ceiling-mounted air conditioner 1 of the present embodiment, a stacked heat exchanger is adopted as the heat exchanger 5, so that the heat exchange rate is high and compactness is possible. A further compactness of the directional dimensions is realized.
し力も、本実施形態の熱交 5は、上下方向に延びる伝熱管 51とフィン 52とが 交互に積層し、かつ、伝熱管 51の上端と下端とがそれぞれ上部ヘッダー管 53と下 部ヘッダー管 54とによって接続されることにより構成されているため、熱交 5の表 面に結露が生じた場合に、その結露水を主として伝熱管 51を経由して速やかに下 方に導くことができるため、結露を伴う熱交換の際にも、高い熱交換効率を維持する ことができる。  In the heat exchange 5 of this embodiment, the heat transfer tubes 51 and the fins 52 extending in the vertical direction are alternately laminated, and the upper and lower ends of the heat transfer tubes 51 are the upper header tube 53 and the lower header tube, respectively. 54, so that when condensation occurs on the surface of the heat exchanger 5, the condensed water can be quickly led downward mainly through the heat transfer pipe 51. High heat exchange efficiency can be maintained even during heat exchange with condensation.
また、熱交換器 5は、ケーシング 2の側面視 (すなわち、ケーシング 2を長手方向か ら見た際）において、傾斜して配置されているため、ケーシング 2の高さ方向寸法のコ ンパクトイ匕を実現しつつ、熱交 5の伝熱面積を大きくすることができるようになつ ている。  In addition, since the heat exchanger 5 is inclined when the casing 2 is viewed from the side (that is, when the casing 2 is viewed from the longitudinal direction), the heat exchanger 5 is provided with a compact size of the casing 2 in the height direction. While realizing this, the heat transfer area of heat exchange 5 can be increased.
[0046] さらに、熱交換器 5は、ケーシング 2の側面視 (すなわち、ケーシング 2を長手方向 から見た際）において、複数の送風ファン 3に対して、上部が下部よりも遠い側に傾斜 して配置されているため、ケーシング 2の下面に吹出口が配置される形態 (すなわち 、天井埋込型の形態)の場合に、吹出口に干渉することなく熱交換器 5を配置するこ とができるようになって!/、る。  [0046] Further, the heat exchanger 5 has an upper portion inclined to a side farther than the lower portion with respect to the plurality of blower fans 3 in a side view of the casing 2 (that is, when the casing 2 is viewed from the longitudinal direction). Therefore, when the air outlet is arranged on the lower surface of the casing 2 (that is, a ceiling-embedded type), the heat exchanger 5 can be arranged without interfering with the air outlet. I can do it!
(5)変形例 1  (5) Modification 1
上述の実施形態においては、熱交換器 5として、上下方向に延びる伝熱管 51とフィ ン 52とが交互に積層し、かつ、伝熱管 51の上端と下端とがそれぞれ上部ヘッダー管 53と下部ヘッダー管 54とによって接続されることにより構成された積層型熱交 を 採用している力 図 17に示されるように、水平方向に延びる伝熱管 51とフィンとが交 互に積層し、かつ、伝熱管 51の一側端と他側端とがそれぞれ第 1側部ヘッダー管 53 と第 2側部ヘッダー管 54とによって接続されることにより構成された積層型熱交 を採用してもよい。  In the above embodiment, as the heat exchanger 5, the heat transfer tubes 51 and fins 52 extending in the vertical direction are alternately stacked, and the upper end and the lower end of the heat transfer tubes 51 are the upper header tube 53 and the lower header, respectively. Force adopting laminated heat exchange constructed by connecting with tube 54 As shown in FIG. 17, heat transfer tubes 51 and fins extending in the horizontal direction are alternately laminated, and A laminated heat exchanger configured by connecting one end and the other end of the heat pipe 51 by the first side header pipe 53 and the second side header pipe 54 may be employed.
[0047] この空気調和装置 1では、伝熱管 51が水平方向に延びており、熱交換器 5を構成 する伝熱管 51の本数を少なくすることができるとともにヘッダー管 53、 53の長さを短 くすることができるため、ケーシングの高さ方向寸法のコンパクトィ匕を実現しつつ、熱 交換性能を高めることができる。 [0047] In the air conditioner 1, the heat transfer tube 51 extends in the horizontal direction to constitute the heat exchanger 5. The number of heat transfer tubes 51 to be reduced can be reduced and the lengths of the header tubes 53 and 53 can be shortened, so that the heat exchange performance is improved while realizing a compact size in the height direction of the casing. be able to.
(6)変形例 2  (6) Modification 2
上述の実施形態においては、熱交換器 5として積層型熱交換器を採用したが、クロ スフイン型熱交翻を採用してもよい。  In the above-described embodiment, a stacked heat exchanger is adopted as the heat exchanger 5, but cross-fin type heat exchange may be adopted.
クロスフィン型熱交^^力もなる熱交^^ 5は、図 18〜20に示されるように、上述 の実施形態と同様、ケーシング 2の平面視において 2つの送風ファン 3の配列方向（ すなわち、ケーシング 2の長手方向）に直交する側に、送風ファン 3の配列方向（すな わち、ケーシング 2の長手方向）に延びており、送風ファン 3を挟むようにケーシング 2 内に配置されている。ここで、図 18は、本変形例にかかる天井設置型の空気調和装 置 1の外観斜視図（天井は省略)である。図 19は、本変形例に力かる空気調和装置 1 の概略側面断面図であって、図 18又は図 20の A— A断面図である。図 20は、本変 形例に力かる空気調和装置 1の概略平面断面図であって、天板 21を取り除いた状 態を示す図である。  As shown in FIGS. 18 to 20, the cross-fin type heat exchange ^^ 5 has the same direction of arrangement of the two blower fans 3 in the plan view of the casing 2 as shown in FIGS. It extends in the arrangement direction of the blower fans 3 (that is, the longitudinal direction of the casing 2) on the side orthogonal to the longitudinal direction of the casing 2 and is arranged in the casing 2 so as to sandwich the blower fan 3 therebetween. . Here, FIG. 18 is an external perspective view (ceiling is omitted) of the ceiling-mounted air conditioner 1 according to this modification. FIG. 19 is a schematic side cross-sectional view of the air conditioner 1 according to this modification, and is a cross-sectional view taken along line AA in FIG. 18 or FIG. FIG. 20 is a schematic plan cross-sectional view of the air conditioner 1 that works on the present modification, and shows a state in which the top plate 21 is removed.
[0048] 熱交換器 5は、図 21に示されるように、略矩形状に形成されたアルミニウム製の多 数のフィン 55と、これらのフィン 55を水平方向に貫通する伝熱管 56とを有して!/、る。 ここで、図 21は、クロスフィン型熱交換器を示す図である。そして、各熱交換器 5には 、上述の実施形態と異なり多段曲げ加工が施されており、ケーシング 2の平面視にお いて、波形形状に成形されている。すなわち、熱交換器 5には、ケーシング 2の平面 視において、送風ファン 3の回転中心 Oを通る鉛直面 (ここでは、側板 22及び側板 2 4に平行な鉛直面）に近づく部分 5aと、送風ファン 3の回転中心 Oを通る鉛直面 (ここ では、側板 22及び側板 24に平行な鉛直面)から遠ざ力る部分 5bとが交互に形成さ れている。尚、本実施形態において、熱交換器 5が送風ファン 3の外周部に最も接近 する位置には、送風ファン 3の回転中心 Oを通る鉛直面 (ここでは、側板 22及び側板 24に平行な鉛直面)から遠ざ力る部分 5bが配置されるように、多段曲げ加工が施さ れている。  [0048] As shown in FIG. 21, the heat exchanger 5 has a large number of aluminum fins 55 formed in a substantially rectangular shape, and heat transfer tubes 56 penetrating these fins 55 in the horizontal direction. And! Here, FIG. 21 is a diagram showing a cross-fin heat exchanger. Each heat exchanger 5 is subjected to multistage bending unlike the above-described embodiment, and is formed into a corrugated shape in a plan view of the casing 2. That is, the heat exchanger 5 has a portion 5a approaching a vertical plane (here, a vertical plane parallel to the side plate 22 and the side plate 24) passing through the rotation center O of the blower fan 3 in a plan view of the casing 2, and The vertical portions passing through the rotation center O of the fan 3 (here, vertical surfaces parallel to the side plate 22 and the side plate 24) are alternately formed with the portions 5b that move away. In the present embodiment, the position where the heat exchanger 5 is closest to the outer periphery of the blower fan 3 is a vertical plane passing through the rotation center O of the blower fan 3 (here, a vertical plane parallel to the side plate 22 and the side plate 24). Multi-step bending is performed so that the portion 5b that is moved away from the surface) is placed.
[0049] 尚、熱交換器 5の構造や配置を除いた本変形例に力かる空気調和装置 1の構成に っ 、ては、熱交換器 5の波形形状に合わせてドレンパン 2bのドレン受け部 26cが形 成されている点や、補助連通開口用切取線 23b、 25b及び補助連通開口 23a、 25a の形状が略矩形形状になっている点を除いては、基本的に、上述の第 1実施形態の 空気調和装置 1と同じであるため、ここでは説明を省略する（但し、図 18〜図 20に図 1〜図 3と同じ符号を付しておくものとする)。 [0049] It should be noted that the configuration of the air conditioner 1 that works well with the present modification excluding the structure and arrangement of the heat exchanger 5 Therefore, the drain receiving portion 26c of the drain pan 2b is formed in accordance with the waveform shape of the heat exchanger 5, and the shapes of the auxiliary communication opening cut lines 23b and 25b and the auxiliary communication openings 23a and 25a are substantially the same. Except for the rectangular shape, it is basically the same as the air conditioner 1 of the first embodiment described above, and therefore the description thereof is omitted here (however, FIG. 1 to FIG. ~ The same reference numerals as in Fig. 3 shall be given).
このような本変形例の天井設置型の空気調和装置 1においても、上述の第 1実施 形態と同様、ケーシング 2に第 1ィ匕粧パネルとしての天井埋込用化粧パネル 11、 13 又は第 2ィ匕粧パネルとしての天井吊下用化粧パネル 15、 17の ヽずれかを装着する ことにより、空気を本体下面 (具体的には、吸入口 l la、 13a)から吸入して本体下面 (具体的には、下面吹出口 l lb、 12a、 13b)から吹き出す天井埋込型の形態、又は 、空気を本体下面 (具体的には、吸入口 61a、 71a)から吸入して本体側面 (具体的 に ίま、佃 J面吹出口 62a、 64a、 72a, 73a, 74a, 75a)力ら吹き出す天井吊下型の形 態の両方に対応することが可能である。  Also in the ceiling-mounted air conditioner 1 of this modified example, the ceiling-embedded decorative panel 11, 13 or 2 as the first decorative panel in the casing 2 is the same as in the first embodiment described above. Attaching either one of the ceiling hanging decorative panels 15 and 17 as a decorative panel allows air to be sucked from the lower surface of the main body (specifically, the inlets lla and 13a) and the lower surface of the main body (specifically Specifically, it is a ceiling-embedded type that blows out from the bottom air outlet l lb, 12a, 13b), or air is sucked from the bottom surface of the main body (specifically, the intake ports 61a, 71a) to specify the side of the main body (specific However, it is possible to deal with both ceiling-suspended types that blow off force from the J-side outlets 62a, 64a, 72a, 73a, 74a, 75a).
[0050] また、本変形例の空気調和装置 1では、熱交換器 5としてクロスフィン型熱交換器を 採用しているため、熱交換器 5の表面に結露が生じた場合に、その結露水を主として 多数のフィン 55を経由して速やかに下方に導くことができるため、結露を伴う熱交換 の際にも、高い熱交換効率を維持することができるようになっている。 [0050] In addition, in the air conditioner 1 of the present modification, a cross fin heat exchanger is employed as the heat exchanger 5, and therefore, when dew condensation occurs on the surface of the heat exchanger 5, the condensed water Can be quickly led downward through a large number of fins 55, so that high heat exchange efficiency can be maintained even during heat exchange with condensation.
さらに、本変形例の熱交^^ 5では、多段曲げ加工が施されている。より具体的に は、熱交換器 5には、ケーシング 2の平面視において、送風ファン 3の回転中心 Oを 通る鉛直面 (ここでは、側板 22及び側板 24に平行な鉛直面）に近づく部分 5a (すな わち、送風ファン 3の外周部側に向かって突出する部分）が形成されるように、多段 曲げ加工が施されている。これにより、本変形例の熱交換器 5では、ケーシング 2の 高さ方向寸法のコンパクトィ匕を実現しつつ、熱交^^ 5の伝熱面積を大きくすること ができるようになつている。  Furthermore, the heat exchange ^ 5 of this modification is subjected to multi-step bending. More specifically, the heat exchanger 5 has a portion 5a close to a vertical plane (here, a vertical plane parallel to the side plate 22 and the side plate 24) passing through the rotation center O of the blower fan 3 in a plan view of the casing 2. A multi-stage bending process is performed so that a portion projecting toward the outer peripheral side of the blower fan 3 is formed.

As with heat exchange 5 (see Fig. 2), the casing 2 is viewed from the side (ie, When the heat exchanger 5 is viewed from the longitudinal direction), the upper part may be disposed so that the upper part is inclined farther from the lower part than the lower part. Even in this case, the heat transfer area of the heat exchanger ^^ 5 can be increased while realizing the compactness of the casing 2 in the height direction. The heat exchange 5 can be arranged without interfering with the air outlet by being inclined to the farther side.
また、ケーシング 2の高さ方向寸法のコンパクトィ匕を実現しつつ、熱交^^ 5の伝熱 面積の伝熱面積を大きくするために、ケーシング 2を側面視 (すなわち、ケーシング 2 を長手方向から見た際）において、側方、斜め上方又は斜め下方に向力つて突出す る突出部を有する形状にしてもよい。例えば、熱交換器 5の一部が突出した形状とな るように多段曲げ力卩ェを施してもよい。より具体的には、図 22〜図 24に示されるよう に、熱交換器 5を長手方向（すなわち、フィン 55の配列方向）から見た際に、側方、 斜め上方又は斜め下方に向力つて突出する突出部が形成されるように多段曲げカロ ェが施されている。ここで、図 22は、本変形例 3にかかる空気調和装置 1の概略側面 断面図であって、斜め上方に向力つて突出する突出部 5aが形成された熱交 5を 示している。図 23は、本変形例 3にかかる空気調和装置 1の概略側面断面図であつ て、斜め下方に向力つて突出する突出部 5bが形成された熱交翻5を示している。 図 24は、本変形例 3にかかる空気調和装置 1の概略側面断面図であって、下部に斜 め下方に向力つて突出する突出部 5bが形成され、さらに、上部に斜め上方に向かつ て突出する突出部 5aが形成された熱交換器 5を示している。  In addition, in order to increase the heat transfer area of the heat exchange ^^ 5 while realizing the compactness of the height dimension of the casing 2, the casing 2 is viewed from the side (that is, the casing 2 is moved in the longitudinal direction). (When viewed from above), it may have a shape having a protruding portion that protrudes sideward, obliquely upward or obliquely downward. For example, a multi-stage bending force may be applied so that a part of the heat exchanger 5 protrudes. More specifically, as shown in FIGS. 22 to 24, when the heat exchanger 5 is viewed from the longitudinal direction (that is, the direction in which the fins 55 are arranged), the force is directed to the side, diagonally upward or diagonally downward. Multi-stage bending caloe is applied so that the protruding part is formed. Here, FIG. 22 is a schematic side cross-sectional view of the air conditioner 1 according to the third modification, and shows the heat exchange 5 in which the protruding portion 5a protruding obliquely upward is formed. FIG. 23 is a schematic side cross-sectional view of the air-conditioning apparatus 1 according to the third modification, and shows a heat exchanger 5 in which a protruding portion 5b that protrudes obliquely downward is formed. FIG. 24 is a schematic side cross-sectional view of the air conditioner 1 according to the third modification example, in which a protruding portion 5b that protrudes obliquely downward is formed at the lower portion, and further, obliquely upward at the upper portion. The heat exchanger 5 in which the protrusion part 5a which protrudes is formed is shown.

(2)変形例 2  (2) Modification 2
上述の実施形態においては、熱交換器 105として積層型熱交換器を採用したが、 第 1実施形態の変形例 2にかかる熱交翻5と同様に、クロスフィン型熱交翻を採 用してもよい（図 21参照)。  In the above-described embodiment, a stacked heat exchanger is adopted as the heat exchanger 105. However, similarly to the heat exchange 5 according to the second modification of the first embodiment, a cross-fin type heat exchange is employed. (See Figure 21).
[0063] クロスフィン型熱交^^力もなる熱交^^ 105は、図 32に示されるように、上述の 実施形態と同様、ケーシング 102の平面視において送風ファン 103の外周部を囲む ように配置されている。ここで、図 32は、本変形例にかかる空気調和装置 101の概略 平面断面図であって、天板 121を取り除いた状態を示す図である。 [0063] As shown in Fig. 32, the cross-fin type heat exchange ^^ 105 also encloses the outer periphery of the blower fan 103 in the plan view of the casing 102, as shown in FIG. Has been placed. Here, FIG. 32 is a schematic plan sectional view of the air-conditioning apparatus 101 according to the present modification, and shows a state where the top plate 121 is removed.
熱交翻105は、第 1実施形態の変形例 2にかかる熱交翻5と同様に、多段曲げ 加工が施されており、ケーシング 102の平面視において、波形形状に成形されてい る。すなわち、熱交翻 105には、ケーシング 2の平面視において、送風ファン 103 の回転中心 Oを通りかつ各熱交換器 105が対応する側板 122、 123、 124、 125の いずれかと平行な鉛直面に近づく部分 105a (すなわち、送風ファン 103の外周部側 に向力つて突出する部分）と、送風ファン 103の回転中心 Oを通りかつ各熱交換器 1 05が対応する側板 122、 123、 124、 125のいずれかと平行な鉛直面力も遠ざかる 部分 105bとが交互に形成されている。尚、本実施形態において、熱交翻105が 送風ファン 103の外周部に最も接近する位置には、送風ファン 103の回転中心 Oを 通りかつ各熱交換器 105が対応する側板 122、 123、 124、 125のいずれ力と平行 な鉛直面力も遠ざ力る部分 105bが配置されるように、多段曲げ力卩ェが施されている The heat exchange 105 is subjected to multi-stage bending as in the case of the heat exchange 5 according to Modification 2 of the first embodiment, and is formed into a corrugated shape in a plan view of the casing 102. That is, the heat exchanger 105 includes a blower fan 103 in a plan view of the casing 2.

In this embodiment, the side plate 122, 123, 124, through which the heat exchanger 105 is closest to the outer peripheral portion of the blower fan 103, passes through the rotational center O of the blower fan 103 and corresponds to each heat exchanger 105. Multi-stage bending force is applied so that the portion 105b that displaces the vertical surface force parallel to any force of 125, 125 is arranged.
[0064] (3)変形例 3 [0064] (3) Modification 3
また、上述の変形例 2のように熱交 l05としてクロスフィン型熱交 を採用す る場合において、クロスフィン型熱交 カゝらなる熱交 105を、第 2実施形態の 積層型熱交翻力もなる熱交翻 105 (図 26参照）と同様、ケーシング 102を側面 視 (すなわち、熱交翻 105を長手方向から見た際）において、送風ファン 103に対 して上部が下部よりも遠!、側に傾斜するように配置してもよ 、。この場合にお 、ても、 ケーシング 102の高さ方向寸法のコンパクトィ匕を実現しつつ、熱交^^ 105の伝熱 面積を大きくすることができ、また、送風ファン 103に対して、上部が下部よりも遠い 側に傾斜して配置されることで、吹出口に干渉することなく熱交 l05を配置する ことができる。  Further, when cross-fin type heat exchange is adopted as the heat exchange 105 as in the above-described modification 2, the heat exchange 105, which is a cross-fin type heat exchange, is used as the laminated heat exchange of the second embodiment. Similar to heat exchange 105 (see Fig. 26), the upper part of the casing 102 is farther than the lower part of the blower fan 103 when the casing 102 is viewed from the side (ie, when the heat exchange 105 is viewed from the longitudinal direction)! Can be arranged to tilt to the side. Even in this case, the heat transfer area of the heat exchange ^^ 105 can be increased while realizing a compact size of the casing 102 in the height direction. Is arranged so as to be inclined to the side farther from the lower portion, so that the heat exchanger 105 can be arranged without interfering with the blowout port.
[0065] また、ケーシング 102の高さ方向寸法のコンパクトィ匕を実現しつつ、熱交^^ 105 の伝熱面積の伝熱面積を大きくするために、ケーシング 102を側面視 (すなわち、ケ 一シング 102を長手方向から見た際）において、側方、斜め上方又は斜め下方に向 力つて突出する突出部を有する形状にしてもよい。例えば、熱交換器 5の一部が突 出した形状となるように多段曲げ力卩ェを施してもよい。より具体的には、図 33〜図 35 に示されるように、熱交換器 105を長手方向（すなわち、フィン 55の配列方向）から見 た際に、側方、斜め上方又は斜め下方に向かって突出する屈曲部が 1以上形成され るように多段曲げ力卩ェが施されている。ここで、図 33は、本変形例 3にかかる空気調 和装置 101の概略側面断面図であって、斜め上方に向かって突出する突出部 105a が形成された熱交 105を示している。図 34は、本変形例 3にかかる空気調和装 置 101の概略側面断面図であって、斜め下方に向かって突出する突出部 105bが形 成された熱交換器 105を示している。図 35は、本変形例 3にかかる空気調和装置 10 1の概略側面断面図であって、下部に斜め下方に向力つて突出する突出部 105bが 形成され、さらに、上部に斜め上方に向力つて突出する突出部 105aが形成された熱 交翻 105を示している。 [0065] Further, in order to increase the heat transfer area of the heat exchange ^^ 105 while realizing a compact size of the casing 102 in the height direction, the casing 102 is viewed from the side (that is, the case 102). When the sing 102 is viewed from the longitudinal direction), it may have a shape having a projecting portion projecting sideways, obliquely upward or obliquely downward. For example, the multi-stage bending force may be applied so that a part of the heat exchanger 5 protrudes. More specifically, as shown in FIGS. 33 to 35, when the heat exchanger 105 is viewed from the longitudinal direction (that is, the direction in which the fins 55 are arranged), the side, obliquely upward or obliquely downward. Multi-step bending force is applied so that one or more protruding bent parts are formed. Here, FIG. 33 is a schematic side cross-sectional view of the air conditioner 101 according to the third modification example, and a projecting portion 105a projecting obliquely upward. Shows the heat exchange 105 formed. FIG. 34 is a schematic side cross-sectional view of the air-conditioning apparatus 101 according to the third modification, and shows the heat exchanger 105 in which a protruding portion 105b that protrudes obliquely downward is formed. FIG. 35 is a schematic side cross-sectional view of the air conditioner 101 according to the third modification, in which a protruding portion 105b that protrudes obliquely downward is formed in the lower portion, and further, the upward force is inclined upward Thus, a heat exchange 105 in which a protruding portion 105a is formed is shown.
