図６に示すように、ドレンパン６２は底板４６上に支持され、熱交換器室６６の下部に配置されている。ドレンパン６２は、側板３８Ａと仕切板６１との間でユニット本体３５の奥行き方向に略一杯に延在し、その中間部には、上方に突出した熱交換器支持部６９が形成されている。また、断熱材２８は、ドレンパン６２の下面にも設けられている。
室内熱交換器６０は、ユニット本体３５の幅方向に延在する熱交換器支持部６９によって、その下端を支持されている。熱交換器支持部６９には、熱交換器室６６側と調和空気室２１とを連通させる水路が形成されている。 As shown in FIG. 6, the drain pan 62 is supported on the bottom plate 46 and is disposed in the lower part of the heat exchanger chamber 66. The drain pan 62 extends substantially fully in the depth direction of the unit main body 35 between the side plate 38A and the partition plate 61, and a heat exchanger support portion 69 protruding upward is formed at an intermediate portion thereof. The heat insulating material 28 is also provided on the lower surface of the drain pan 62.
The lower end of the indoor heat exchanger 60 is supported by a heat exchanger support 69 that extends in the width direction of the unit body 35. The heat exchanger support 69 is formed with a water channel that allows the heat exchanger chamber 66 side and the conditioned air chamber 21 to communicate with each other.

室内熱交換器６０は、フィンアンドチューブ型の熱交換器であり、通風方向に延びる一対の管板６０Ａと、管板６０Ａの間に互いに間隔を開けて配置される複数のフィン板６０Ｂと、これらフィン板６０Ｂを貫通する複数のチューブ６０Ｃを備えて構成されている。チューブ６０Ｃは、各チューブ６０Ｃの端に設けられたＵ字部によって１本の冷媒配管として連結されている。   The indoor heat exchanger 60 is a fin-and-tube heat exchanger, and includes a pair of tube plates 60A extending in the ventilation direction, and a plurality of fin plates 60B arranged at intervals between the tube plates 60A, A plurality of tubes 60C penetrating these fin plates 60B are provided. The tube 60C is connected as one refrigerant pipe by a U-shaped portion provided at the end of each tube 60C.

室内熱交換器６０はその長手方向においては側板３８Ｃ，３８Ｄ間に延在し、長手方向の一端５９Ａと側板３８Ｄとの間にはユニット本体３５内の幅方向の一側３５Ａに位置する空間Ｓが形成されている。また、室内熱交換器６０は、長手方向の他端５９Ｂ側においてはユニット本体３５内の他側３５Ｂに寄せて配置されている。
室内熱交換器６０は、ガス管及び液管で構成される一対の冷媒配管によって上記室外機（不図示）に接続されており、図５中には一方の冷媒配管４４を図示している。冷媒配管４４は、室内熱交換器６０の長手方向の一端５９Ａに接続され、側板３８Ｃを貫通して延出されている。他方の冷媒配管（不図示）も一端５９Ａにまとめて接続され、側板３８Ｃ側に延出されている。すなわち、冷媒配管４４を含む一対の冷媒配管は、空間Ｓにまとめて配置されている。このため、ユニット本体３５を簡単な構造にできる。 The indoor heat exchanger 60 extends between the side plates 38C and 38D in the longitudinal direction, and a space S positioned on one side 35A in the width direction in the unit body 35 between the longitudinal end 59A and the side plate 38D. Is formed. Further, the indoor heat exchanger 60 is arranged close to the other side 35B in the unit main body 35 on the other end 59B side in the longitudinal direction.
The indoor heat exchanger 60 is connected to the outdoor unit (not shown) by a pair of refrigerant pipes composed of a gas pipe and a liquid pipe, and one refrigerant pipe 44 is shown in FIG. The refrigerant pipe 44 is connected to one end 59A in the longitudinal direction of the indoor heat exchanger 60, and extends through the side plate 38C. The other refrigerant pipe (not shown) is also connected together at one end 59A and extends toward the side plate 38C. That is, the pair of refrigerant pipes including the refrigerant pipe 44 are arranged in the space S together. For this reason, the unit main body 35 can be made into a simple structure.

室内熱交換器６０は、平板状の２つの熱交換器を組み合わせて構成されており、熱交換器室６６の上部に配置される上側熱交換器７１（上側熱交換部）と、下部に配置される下側熱交換器７２（下側熱交換部）とを有している。
上側熱交換器７１及び下側熱交換器７２は、上側熱交換器７１の下端と下側熱交換器７２の上端との間に設けられた連結部７３（くの字の頂点）で連結されており、室内熱交換器６０は、側板３８Ｃの側からの側面視において、両端７４が上下に延びるくの字状に形成されている。連結部７３は、室内熱交換器６０のくの字形状の頂点に対応している。このように、室内熱交換器６０を上下に延びるくの字状に形成したため、平板状の熱交換器を縦置きに配置する場合に比べて、ユニット本体３５内の熱交換器の高さを低くすることができる。
室内熱交換器６０は、連結部７３を通る水平面Ｈを基準に上側熱交換器７１と下側熱交換器７２とが略対称形状となるように形成されており、上側熱交換器７１及び下側熱交換器７２は、ユニット本体３５の高さ方向及び奥行き方向において略同一のサイズを有している。 The indoor heat exchanger 60 is configured by combining two flat heat exchangers, and is arranged at the upper heat exchanger 71 (upper heat exchanging portion) disposed at the upper portion of the heat exchanger chamber 66 and at the lower portion. And a lower heat exchanger 72 (lower heat exchanging part).
The upper heat exchanger 71 and the lower heat exchanger 72 are connected by a connecting portion 73 (vertical vertex) provided between the lower end of the upper heat exchanger 71 and the upper end of the lower heat exchanger 72. The indoor heat exchanger 60 is formed in a dogleg shape in which both ends 74 extend vertically when viewed from the side of the side plate 38C. The connecting portion 73 corresponds to the top of the dog-shaped shape of the indoor heat exchanger 60. Thus, since the indoor heat exchanger 60 was formed in the shape of a square extending up and down, the height of the heat exchanger in the unit main body 35 can be increased as compared with the case where the flat plate heat exchanger is arranged vertically. Can be lowered.
The indoor heat exchanger 60 is formed such that the upper heat exchanger 71 and the lower heat exchanger 72 are substantially symmetrical with respect to a horizontal plane H passing through the connecting portion 73. The side heat exchanger 72 has substantially the same size in the height direction and depth direction of the unit body 35.

熱交換器室６６には、ファン５５の吹き出し口６８と室内熱交換器６０とを離して配置することで、仕切板６１と室内熱交換器６０との間に位置する空間Ｐが設けられており、ドレンポンプ６３は、空間Ｐにおいてユニット本体３５内の一側３５Ａに配置されている。空間Ｐは熱交換器室６６の隅部において空間Ｓに連続しており、ドレンポンプ６３は、冷媒配管４４を含む一対の冷媒配管に隣接して配置されている。
側板３８Ｃの面においてドレンポンプ６３の近傍には、ドレンポンプ６３や冷媒配管等のメンテナンス時に開かれる開口を塞ぐ蓋板２５が設けられている。 The heat exchanger chamber 66 is provided with a space P located between the partition plate 61 and the indoor heat exchanger 60 by disposing the outlet 68 of the fan 55 and the indoor heat exchanger 60 apart from each other. The drain pump 63 is disposed on one side 35 </ b> A in the unit main body 35 in the space P. The space P is continuous with the space S at the corner of the heat exchanger chamber 66, and the drain pump 63 is disposed adjacent to the pair of refrigerant pipes including the refrigerant pipe 44.
On the surface of the side plate 38C, in the vicinity of the drain pump 63, a cover plate 25 that closes an opening that is opened during maintenance of the drain pump 63, the refrigerant piping, and the like is provided.

図６に示すように、室内熱交換器６０は、くの字形状の開放側７５がファン５５の吹き出し口６８に対向する向きで配置されている。すなわち、室内熱交換器６０は、くの字の両端７４がファン５５の側を向き、くの字の頂点である連結部７３が調和空気室２１側を向く向きで配置されている。くの字の両端７４とファン５５の吹き出し口６８との間には、ドレンポンプ６３を配置可能な大きさの間隔Ｇが奥行き方向に確保されている。このように、間隔Ｇが確保されており、吹き出し口６８から吹き出された気流は吹き出し口６８から離れるに従って上下方向及び幅方向に広がるため、上側熱交換器７１及び下側熱交換器７２に満遍なく送風を行き渡らせることができる。   As shown in FIG. 6, the indoor heat exchanger 60 is arranged in such a direction that the open side 75 of the U shape faces the outlet 68 of the fan 55. In other words, the indoor heat exchanger 60 is arranged in such a manner that the both ends 74 of the square shape face the fan 55 side and the connecting portion 73 that is the apex of the square shape faces the conditioned air chamber 21 side. A gap G that is large enough to arrange the drain pump 63 is secured in the depth direction between the both ends 74 of the square shape and the outlet 68 of the fan 55. In this way, the gap G is secured, and the airflow blown out from the blowout port 68 spreads in the vertical direction and the width direction as the distance from the blowout port 68 increases, so that the upper heat exchanger 71 and the lower heat exchanger 72 are evenly distributed. You can spread the blast.

ファン５５の吹き出し口６８は、室内熱交換器６０の上部に位置し、室内熱交換器６０の全体に満遍なく送風できるように、連結部７３の側に下方に傾けて配置されている。詳細には、吹き出し口６８の吹き出し通路の下面及び上面を構成する下壁６８Ａ及び上壁６８Ｂは、連結部７３の側に向けて下方に傾斜して設けられている。吹き出し口６８の上下方向の中間点Ｍは、連結部７３を通る水平面Ｈの延長線上から上方に外れた位置に位置しており、ファン５５の気流は下壁６８Ａ及び上壁６８Ｂに沿って吹き出され、中間点Ｍからの気流は連結部７３の周辺に到達する。   The blower outlet 68 of the fan 55 is located at the upper part of the indoor heat exchanger 60 and is tilted downward toward the connecting portion 73 so that the entire indoor heat exchanger 60 can be blown uniformly. Specifically, the lower wall 68A and the upper wall 68B constituting the lower surface and the upper surface of the blowing passage of the blowing port 68 are provided so as to be inclined downward toward the connecting portion 73 side. The midpoint M in the vertical direction of the blowout port 68 is located at a position deviating upward from the extension of the horizontal plane H passing through the connecting portion 73, and the airflow of the fan 55 blows out along the lower wall 68A and the upper wall 68B. Then, the airflow from the intermediate point M reaches the periphery of the connecting portion 73.

ここで、図５及び図６を参照し、ファン５５から吹き出される気流について説明する。なお、図５及び図６では、気流の向きを矢印で示しており、矢印の長さは風量に対応している。
ファン５５はシロッコファンであり、吹き出し口６８の中央部から吹き出される風量が最も大きく、中央部よりも外側から吹き出される風量は、中央から吹き出される風量よりも小さくなっている。従って、図５及び図６では、中央部の気流Ｘ１，Ｚ１の風量が大きく、外側から吹き出される気流Ｘ２，Ｚ２及び気流Ｘ３，Ｚ３の風量は、気流Ｘ１，Ｚ１よりも小さい。 Here, the airflow blown out from the fan 55 will be described with reference to FIGS. 5 and 6. 5 and 6, the direction of the airflow is indicated by an arrow, and the length of the arrow corresponds to the air volume.
The fan 55 is a sirocco fan, and the amount of air blown from the central portion of the outlet 68 is the largest, and the amount of air blown from the outside of the central portion is smaller than the amount of air blown from the center. Therefore, in FIGS. 5 and 6, the airflows of the airflows X1 and Z1 at the center are large, and the airflows of the airflows X2 and Z2 and the airflows X3 and Z3 blown from the outside are smaller than the airflows X1 and Z1.

図５に示すように、吹き出し口６８が室内熱交換器６０の長手方向の中間部に対応した位置に配置されているため、室内熱交換器６０の長手方向に満遍なく送風でき、熱交換の効率を良好にできる。また、吹き出し口６８と室内熱交換器６０との間に間隔Ｇが設けられており、気流Ｘ２，Ｘ３のように気流が十分に広がって長手方向の一端５９Ａ及び他端５９Ｂに到達するため、長手方向に満遍なく送風できる。   As shown in FIG. 5, since the outlet 68 is disposed at a position corresponding to the middle portion of the indoor heat exchanger 60 in the longitudinal direction, the air can be uniformly blown in the longitudinal direction of the indoor heat exchanger 60, and the efficiency of heat exchange Can be improved. In addition, a gap G is provided between the air outlet 68 and the indoor heat exchanger 60, and the airflow sufficiently spreads like the airflows X2 and X3 to reach the one end 59A and the other end 59B in the longitudinal direction. Can blow evenly in the longitudinal direction.

図６に示すように、室内熱交換器６０は、くの字の開放側７５がファン５５の吹き出し口６８に対向する向きで配置されており、上側熱交換器７１及び下側熱交換器７２は、連結部７３の側に行くほど吹き出し口６８から離間し、両端７４の側に行くほど吹き出し口６８に近くなっている。吹き出し口６８の上下方向の中間点Ｍから吹き出される気流Ｚ１は、中間点Ｍの外側の気流Ｚ２，Ｚ３よりも風量が大きくなっている。このため、吹き出し口６８から離れている連結部７３の近傍にも十分な風量を供給することができる。また、室内熱交換器６０における両端７４の近傍の部分が吹き出し口６８の近くに位置しているため、気流Ｚ１よりも風量の小さい気流Ｚ２，Ｚ３であっても、両端７４の近傍の部分に十分な風量を供給できる。   As shown in FIG. 6, the indoor heat exchanger 60 is arranged such that the open side 75 of the letter “U” faces the outlet 68 of the fan 55, and the upper heat exchanger 71 and the lower heat exchanger 72 are arranged. Is more distant from the outlet 68 as it goes to the connecting portion 73 side, and closer to the outlet 68 as it goes to both ends 74 side. The airflow Z1 blown out from the middle point M in the vertical direction of the outlet 68 has a larger air volume than the airflows Z2 and Z3 outside the middle point M. For this reason, sufficient air volume can be supplied also to the vicinity of the connection part 73 which is distant from the blower outlet 68. Further, since the portion in the vicinity of both ends 74 in the indoor heat exchanger 60 is located near the outlet 68, even in the case of the airflows Z2 and Z3 having a smaller air volume than the airflow Z1, the portion in the vicinity of both ends 74 Sufficient air volume can be supplied.

このように、中間点Ｍからの気流Ｚ１の風量が大きいファン５５の風量の分布に対応させて、室内熱交換器６０を、くの字の開放側７５がファン５５の吹き出し口６８に対向する向きで配置するとともに、気流Ｚ１が連結部７３に到達する向きで吹き出し口６８を配置したため、室内熱交換器６０の上下方向において満遍なく送風を行き渡らせることができ、熱交換の効率を良好にすることができる。
また、吹き出し口６８と室内熱交換器６０との間に間隔Ｇが設けられており、気流Ｚ２，Ｚ３のように気流が十分に広がって高さ方向の端に相当する両端７４に到達するため、高さ方向に満遍なく送風できる。 In this way, the indoor heat exchanger 60 is made to correspond to the distribution of the air volume of the fan 55 where the air volume Z1 from the intermediate point M is large. Since the air outlet Z is arranged in the direction in which the airflow Z1 reaches the connecting portion 73, the air can be evenly distributed in the vertical direction of the indoor heat exchanger 60, and the heat exchange efficiency is improved. be able to.
Further, a gap G is provided between the air outlet 68 and the indoor heat exchanger 60, so that the air flow sufficiently spreads and reaches both ends 74 corresponding to the ends in the height direction like the air flows Z2 and Z3. , Can blow evenly in the height direction.

以上説明したように、本発明を適用した第１の実施の形態によれば、上側熱交換器７１及び下側熱交換器７２が側面視でくの字に連結されることで室内熱交換器６０が設けられ、くの字の頂点である連結部７３に対向させてファン５５の吹き出し口６８を設けたため、室内熱交換器６０の高さを低くできるとともに、ファン５５と室内熱交換器６０との間の距離が大きく不均一になることがない。このため、ユニット本体３５の高さを抑えつつ、熱交換の効率を良好にすることができる。   As described above, according to the first embodiment to which the present invention is applied, the upper heat exchanger 71 and the lower heat exchanger 72 are connected in a square shape in a side view so that the indoor heat exchanger is 60 is provided, and the blowout port 68 of the fan 55 is provided so as to oppose the connecting portion 73 that is the apex of the character, so that the height of the indoor heat exchanger 60 can be reduced, and the fan 55 and the indoor heat exchanger 60 can be reduced. The distance between and is not greatly uneven. For this reason, it is possible to improve the efficiency of heat exchange while suppressing the height of the unit body 35.

また、吹き出し口６８の中間点Ｍからの気流Ｚ１を連結部７３に向けて送風することで、ファン５５の吹き出し口６８の中間点Ｍが室内熱交換器６０の連結部７３を通る水平面Ｈの延長線上から上方に外れた位置にある構成であっても、上側熱交換器７１及び下側熱交換器７２に満遍なく送風を行き渡らせることができ、熱交換の効率を良好にすることができる。
また、室内熱交換器６０のくの字の開放側７５がファン５５の吹き出し口６８に対向しており、室内熱交換器６０の空気の入口側の形状がファン５５の風量の分布に対応しているため、熱交換の効率を良好にすることができる。 Further, the air flow Z1 from the intermediate point M of the outlet 68 is blown toward the connecting portion 73, whereby the intermediate point M of the outlet 68 of the fan 55 is on the horizontal plane H passing through the connecting portion 73 of the indoor heat exchanger 60. Even if it is the structure which exists in the position which deviated upwards from the extension line, ventilation can be uniformly distributed to the upper side heat exchanger 71 and the lower side heat exchanger 72, and the efficiency of heat exchange can be made favorable.
Further, the open side 75 of the square shape of the indoor heat exchanger 60 faces the outlet 68 of the fan 55, and the shape of the air inlet side of the indoor heat exchanger 60 corresponds to the air volume distribution of the fan 55. Therefore, the efficiency of heat exchange can be improved.

さらに、ファン５５の吹き出し口６８と室内熱交換器６０とを間隔Ｇをあけて配置することで、吹き出し口６８からの送風の範囲が広がるため、室内熱交換器６０の端部にも送風を行き渡らせることができ、熱交換の効率を良好にすることができる。また、ドレンポンプ６３及び冷媒配管４４を含む一対の冷媒配管をユニット本体３５内の幅方向の一側３５Ａにまとめて設けたため、ユニット本体３５を簡単な構造にできる。
また、ファン５５は遠心送風機であるシロッコファンであるため、大きな静圧を得ることができ、ファン５５の下流に室内熱交換器６０、及び、天井板３３まで延びる比較的長い吹出ダクト３６を備えた構成であっても、大きな送風量を得ることができる。 Furthermore, by arranging the air outlet 68 of the fan 55 and the indoor heat exchanger 60 with a gap G, the range of air blowing from the air outlet 68 is widened, so that air is also blown to the end of the indoor heat exchanger 60. Thus, the heat exchange efficiency can be improved. In addition, since the pair of refrigerant pipes including the drain pump 63 and the refrigerant pipe 44 are collectively provided on one side 35A in the width direction in the unit main body 35, the unit main body 35 can have a simple structure.
Further, since the fan 55 is a sirocco fan that is a centrifugal blower, a large static pressure can be obtained, and the indoor heat exchanger 60 and a relatively long blow-out duct 36 extending to the ceiling plate 33 are provided downstream of the fan 55. Even with this configuration, a large air flow rate can be obtained.

なお、上記第１の実施の形態は本発明を適用した一態様を示すものであって、本発明は上記第１の実施の形態に限定されない。
上記第１の実施の形態では、くの字の頂点は、連結部７３であるものとして説明したが、本発明はこれに限定されるものではなく、上側熱交換器７１及び下側熱交換器７２がくの字に一体に設けられた熱交換器におけるくの字の頂点であっても良い。 In addition, the said 1st Embodiment shows the one aspect | mode which applied this invention, Comprising: This invention is not limited to the said 1st Embodiment.
In the said 1st Embodiment, although the vertex of the character-shape demonstrated as what was the connection part 73, this invention is not limited to this, The upper side heat exchanger 71 and the lower side heat exchanger 72 may be the apex of the character in the heat exchanger provided integrally with the character.

［第２の実施の形態］
以下、図７を参照して、本発明を適用した第２の実施の形態について説明する。この第２の実施の形態において、上記第１の実施の形態と同様に構成される部分については、同符号を付して説明を省略する。
第２の実施の形態のユニット本体１３５では、くの字に連結された室内熱交換器６０が、側板３８Ｃの側からの側面視において、逆くの字となるように配置されている点が上記第１の実施の形態と異なっている。 [Second Embodiment]
Hereinafter, a second embodiment to which the present invention is applied will be described with reference to FIG. In the second embodiment, parts that are configured in the same manner as in the first embodiment are given the same reference numerals, and descriptions thereof are omitted.
In the unit main body 135 of the second embodiment, the indoor heat exchanger 60 connected to the letter “U” is arranged so as to have an inverted letter in a side view from the side plate 38C side. This is different from the first embodiment.

図７は、第２の実施の形態におけるユニット本体３５内の構成を示す側面図である。
図７に示すように、室内熱交換器６０は、熱交換器室６６内において、くの字の開放側７５が室内熱交換器６０の下流側に向けた状態で配置されており、連結部７３はファン５５の吹き出し口６８に対向している。すなわち、室内熱交換器６０は、くの字の両端７４が、室内熱交換器６０の下流に位置する調和空気室１２１側を向き、くの字の頂点である連結部７３がファン５５の側を向く向きで、側板３８Ｃの側からの側面視において、逆くの字となるように配置されている。くの字の頂点の連結部７３とファン５５の吹き出し口６８との間には、ドレンポンプ６３を配置可能な大きさの間隔Ｇが奥行き方向に確保されている。
吹き出し口６８の上下方向の中間点Ｍから吹き出される気流Ｚ１は、下壁６８Ａ及び上壁６８Ｂに沿って吹き出され、連結部７３の近傍に流れる。 FIG. 7 is a side view showing a configuration inside the unit main body 35 in the second embodiment.
As shown in FIG. 7, the indoor heat exchanger 60 is disposed in the heat exchanger chamber 66 in a state where the open side 75 of the “<” shape is directed to the downstream side of the indoor heat exchanger 60. 73 faces the outlet 68 of the fan 55. That is, in the indoor heat exchanger 60, both ends 74 of the letter “U” face the conditioned air chamber 121 side located downstream of the indoor heat exchanger 60, and the connecting portion 73 that is the apex of the letter “U” is on the fan 55 side. In the direction facing the side plate 38, the side plate 38 </ b> C is disposed so as to be reversed in a side view from the side. A gap G having a size that allows the drain pump 63 to be disposed is secured in the depth direction between the connecting portion 73 at the top of the square shape and the outlet 68 of the fan 55.
The airflow Z1 blown from the middle point M in the vertical direction of the blowout port 68 is blown along the lower wall 68A and the upper wall 68B and flows in the vicinity of the connecting portion 73.

第２の実施の形態では、くの字の両端７４が調和空気室１２１の側に延びており、側板３８Ａとくの字の両端７４との距離が短いため、調和空気室１２１の上面１２１Ａの奥行き方向の長さが小さくなっている。このため、調和空気室１２１の上面１２１Ａを覆う断熱材１２８の奥行き方向の長さを小さくでき、断熱材１２８の使用量を削減できる。
また、ドレンパン６２に設けられた熱交換器支持部１６９は、側板３８Ａの側に寄せて形成されている。 In the second embodiment, both ends 74 of the letter-shaped portion extend to the conditioned air chamber 121 side, and the distance between the side plate 38A and both ends 74 of the letter-shaped shape is short, so that the depth of the upper surface 121A of the conditioned air chamber 121 is increased. The direction length is smaller. For this reason, the length of the heat insulating material 128 covering the upper surface 121A of the conditioned air chamber 121 in the depth direction can be reduced, and the amount of the heat insulating material 128 used can be reduced.
Further, the heat exchanger support 169 provided in the drain pan 62 is formed close to the side plate 38A.
