Description

本発明は、小型化大容量化を図ったダクト型空気調和機に関する。   The present invention relates to a duct-type air conditioner that is reduced in size and increased in capacity.

ダクト型空気調和機に、送風ファンとしてシロッコファンを使用したものがある。シロッコファンを使用したダクト型空気調和機は、そのシロッコファンの大きさ、対応する熱交換器の形状等によって、熱交換器に当たる風の風速分布を均一化して熱交換効率を高くする取り組みが行われてきた。   Some duct-type air conditioners use a sirocco fan as a blower fan. Duct type air conditioners that use sirocco fans are making efforts to increase the heat exchange efficiency by making the wind speed distribution of the heat exchanger uniform, depending on the size of the sirocco fan and the shape of the corresponding heat exchanger. I have been.

しかし、シロッコファンは、渦巻き状のケーシングを備え、両側から空気を吸い込み、正面から空気を吹き出す構造であるので、風速分布が偏在しているため、このシロッコファンを使用したダクト型空気調和機では、風速分布の飛躍的な改善には至っていない。このため、熱交換効率向上は十分ではなく、熱変換容量不足を招く。特許文献１にシロッコファンを使用した室内機についての記載がある。   However, since the sirocco fan has a spiral casing, sucks air from both sides, and blows out air from the front, the wind speed distribution is unevenly distributed, so in a duct-type air conditioner using this sirocco fan The wind speed distribution has not improved dramatically. For this reason, the heat exchange efficiency is not sufficiently improved, resulting in insufficient heat conversion capacity. Patent Document 1 describes an indoor unit using a sirocco fan.

熱変換容量の増大化は、大面積の熱交換器を使用するとともに大きなシロッコファンを使用することで実現することができるが、大きなシロッコファンは装置の大型化を招くので、独立した個々のモータで駆動される複数のシロッコファンを使用することが行われる。しかし、この場合でも装置全体の大型化を回避することは困難であり、またコスト高を招く。   An increase in heat conversion capacity can be realized by using a large-area heat exchanger and a large sirocco fan. However, a large sirocco fan leads to an increase in the size of the device, so that an independent individual motor is used. Using a plurality of sirocco fans driven by However, even in this case, it is difficult to avoid an increase in the size of the entire apparatus, and the cost is increased.

一方、ターボファンを使用する送風装置が、特許文献２で提案されている。このターボファンを室内機に使用すれば、風速分布の均一化をはかることができるが、送風面積を大きくするためには複数台のターボファンを使用する必要があり、この場合でも、個々のターボファンを駆動する複数のモータが必要であり、上記同様に装置の大型化やコスト高を招くことになる。   On the other hand, Patent Document 2 proposes a blower using a turbo fan. If this turbo fan is used in an indoor unit, the wind speed distribution can be made uniform, but in order to increase the blowing area, it is necessary to use multiple turbo fans. A plurality of motors for driving the fan are necessary, and as described above, the apparatus is increased in size and cost.

Is mounted with a screw or the like (not shown) in the central opening 41 of the motor mount 40 spanned by

５０Ａ，５０Ｂは薄型の第１、第２のターボファンであり、第１のターボファン５０Ａはモータ３０の第１の出力軸３１に取り付けられ、第２のターボファン５０Ｂはモータ３０の第２の出力軸３２に取り付けられている。   Reference numerals 50A and 50B denote thin first and second turbofans. The first turbofan 50A is attached to the first output shaft 31 of the motor 30, and the second turbofan 50B is the second turbofan 50B. It is attached to the output shaft 32.

６０Ａ，６０Ｂは風向ガイド板であり、空気吸込口１１から吸い込まれた風をターボファン５０Ａ，５０Ｂのそれぞれに個々に導く。この風向ガイド板６０Ａ，６０Ｂは、湾曲した背面板６１Ａ，６１Ｂ、この背面板６１Ａ，６１Ｂに直線的に連続する側面板６２Ａ，６３Ａ，６２Ｂ，６３Ｂ（ただし、６２Ｂ，６３Ｂは図示せず）、吸込開口部６４Ａａ，６４Ｂａを有する板材６４Ａ，６４Ｂ、および熱交換器２０Ａ，２０Ｂに対向し横方向に拡開した吹出用開口６５Ａ，６５Ｂを備える。板材６４Ａは風向ガイド板６０Ａの下面を構成し、板材６４Ｂは風向ガイド板６０Ｂの上面を構成する。吹出用開口６５Ａ，６５Ｂの開口横幅は熱交換器２０Ａ，２０Ｂの横幅Ｗに対応している。なお、風向ガイド板６０Ａの上面側を閉じて上面を形成する上面板には筐体１０の上面壁１０ａの一部が共用され、風向ガイド板６０Ｂの下面側を閉じて下面を形成する下面板には筐体１１の下面壁１０ｂの一部が共用されている。６６は仕切板であり、風向ガイド板６０Ａ，６０Ｂの奥壁の一部を構成し、空気吸込口１１から吸い込まれた空気が熱交換器２０Ａ，２０Ｂの方向へ直接通過することを阻止して、その空気をターボファン５０Ａ，５０Ｂに導くように作用する。この仕切板６６は、熱交換器２０Ａ，２０Ｂとターボファン５０Ａ，５０Ｂとの間を仕切るように、筐体１０の両側の側面壁１０ｃ，１０ｄの間に縦になった姿勢で横方向（図１において紙面に垂直方向）に配置されている。   Reference numerals 60A and 60B denote wind direction guide plates which individually guide the wind sucked from the air suction port 11 to the turbo fans 50A and 50B. The wind direction guide plates 60A, 60B are curved back plates 61A, 61B, side plates 62A, 63A, 62B, 63B linearly continuous to the back plates 61A, 61B (however, 62B, 63B are not shown), Plate members 64A and 64B having suction openings 64Aa and 64Ba, and blowout openings 65A and 65B that are widened in the lateral direction are provided facing the heat exchangers 20A and 20B. The plate material 64A constitutes the lower surface of the wind direction guide plate 60A, and the plate material 64B constitutes the upper surface of the wind direction guide plate 60B. The opening widths of the blowing openings 65A and 65B correspond to the width W of the heat exchangers 20A and 20B. A part of the upper surface wall 10a of the housing 10 is shared by the upper surface plate that closes the upper surface side of the wind direction guide plate 60A and forms the upper surface, and the lower surface plate that closes the lower surface side of the wind direction guide plate 60B and forms the lower surface. A part of the lower wall 10b of the housing 11 is shared. Reference numeral 66 denotes a partition plate, which constitutes a part of the back wall of the wind direction guide plates 60A and 60B and prevents the air sucked from the air suction port 11 from passing directly in the direction of the heat exchangers 20A and 20B. The air is guided to the turbo fans 50A and 50B. The partition plate 66 has a vertical orientation between the side walls 10c and 10d on both sides of the housing 10 so as to partition the heat exchangers 20A and 20B and the turbofans 50A and 50B (see FIG. 1 in a direction perpendicular to the paper surface).

熱交換器２０Ａは、風向ガイド板６０Ａの吹出用開口６５Ａに対面する上側が空気吹出口１２の側となり、モータ３０に対面する下側が風向ガイド板６０Ａの側となるように、通風方向に対して傾斜している。つまり、上面２０Ａａが風向ガイド板６０Ａに向き、下面２０Ａｂが空気吹出口１２に向くように傾斜して配置されている。   In the heat exchanger 20A, the upper side facing the blowing opening 65A of the airflow direction guide plate 60A is the air outlet 12 side, and the lower side facing the motor 30 is the airflow direction guide plate 60A side with respect to the airflow direction. Is inclined. That is, the upper surface 20Aa is inclined and arranged so that the airflow direction guide plate 60A faces and the lower surface 20Ab faces the air outlet 12.

また、熱交換器２０Ｂは、風向ガイド板６０Ｂの吹出用開口６５に対面する下側が空気吹出口１２の側となり、モータ３０に対面する上側が風向ガイド板６０Ｂの側となるように、通風方向に対して傾斜している。つまり、下面２０Ｂｂが風向ガイド板６０Ｂに向き、上面２０Ｂａが空気吹出口１２に向くように傾斜して配置されている。   Further, in the heat exchanger 20B, the airflow direction is such that the lower side facing the blowout opening 65 of the airflow direction guide plate 60B is the air outlet 12 side and the upper side facing the motor 30 is the airflow direction guide plate 60B side. It is inclined with respect to. That is, the lower surface 20Bb is inclined and arranged so that the airflow direction guide plate 60B faces and the upper surface 20Ba faces the air outlet 12.

これにより、熱交換器２０Ａ，２０Ｂは、前記したように、側面から見て空気吹出口１２の側に開く横Ｖ字形状に配置されている。   Thereby, heat exchanger 20A, 20B is arrange | positioned at the horizontal V shape opened to the side of the air blower outlet 12 seeing from a side surface as mentioned above.

９０は室外機（図示せず）に接続される冷媒配管接続ナットである。   Reference numeral 90 denotes a refrigerant pipe connection nut connected to an outdoor unit (not shown).

さて、空気吸込口１１から吸い込まれた空気は、第１のターボファン５０Ａの回転により、風向ガイド板６０Ａの吸込用開口６４Ａａから第１のターボファン５０Ａに吸い込まれ、吹出用開口６５Ａから熱交換器２０Ａに吹き付けられ、そこで冷媒と熱交換されてから、空気吹出口１２より吹出される。   Now, the air sucked from the air suction port 11 is sucked into the first turbofan 50A from the suction opening 64Aa of the wind direction guide plate 60A by the rotation of the first turbofan 50A, and heat exchange is performed from the blowout opening 65A. The air is blown to the container 20 </ b> A, and heat is exchanged with the refrigerant there.

このとき、熱交換器２０Ａは、上面２０Ａａが風向ガイド板６０Ａに向き、下面２０Ａｂが空気吹出口１２に向くように傾斜して配置されており、風向ガイド板６０Ａの吹出用開口６５Ａは横方向に拡開されているので、第１のターボファン５０Ａから吹き出される風のほぼすべてが熱交換器２０Ａの上面２０Ａａの全面に当たることになる。しかも、第１のターボファン５０Ａは上側の風力が下側の風力よりも強いが、熱交換器２０Ａが傾斜しているため、熱交換器２０Ａの上面２０Ａａの上側が第１のターボファン５０Ａから遠くなるので、熱交換器２０Ａの上面２０Ａａの全体への風圧はほぼ平均化されることになる。   At this time, the heat exchanger 20A is arranged so as to be inclined so that the upper surface 20Aa faces the wind direction guide plate 60A and the lower surface 20Ab faces the air outlet 12, and the blowout opening 65A of the wind direction guide plate 60A is in the lateral direction. Therefore, almost all of the air blown from the first turbofan 50A hits the entire upper surface 20Aa of the heat exchanger 20A. Moreover, although the upper wind force of the first turbofan 50A is stronger than the lower wind force, since the heat exchanger 20A is inclined, the upper side of the upper surface 20Aa of the heat exchanger 20A extends from the first turbofan 50A. Since the distance increases, the wind pressure over the entire upper surface 20Aa of the heat exchanger 20A is substantially averaged.

また、空気吸込口１１から吸い込まれた空気は、第２のターボファン５０Ｂの回転により、風向ガイド板６０Ｂの吸込用開口６４Ｂａから第２のターボファン５０Ｂに吸い込まれ、吹出用開口６５Ｂから熱交換器２０Ｂに吹き付けられ、そこで冷媒と熱交換されてから、空気吹出口１２より吹出される。   The air sucked from the air suction port 11 is sucked into the second turbofan 50B from the suction opening 64Ba of the wind direction guide plate 60B by the rotation of the second turbofan 50B, and heat exchange is performed from the blowout opening 65B. The air is blown to the container 20 </ b> B, where heat is exchanged with the refrigerant, and then blown out from the air outlet 12.

このとき、熱交換器２０Ｂは、下面２０Ｂｂが風向ガイド板６０Ｂに向き、上面２０Ｂａが空気吹出口１２に向くように傾斜して配置されており、風向ガイド板６０Ｂの吹出用開口６５Ｂは横方向に拡開されているので、第２のターボファン５０Ｂから吹き出される風のほぼすべてが熱交換器２０Ｂの下面２０Ｂｂの全面に当たることになる。しかも、第２のターボファン５０Ｂは下側の風力が上側の風力よりも強いが、熱交換器２０Ｂが傾斜しているため、熱交換器２０Ｂの下面２０Ｂｂの下側が第２のターボファン５０Ｂから遠くなるので、熱交換器２０Ｂの下面２０Ｂｂの全体への風圧はほぼ平均化されることになる。   At this time, the heat exchanger 20B is arranged so as to be inclined such that the lower surface 20Bb faces the wind direction guide plate 60B and the upper surface 20Ba faces the air outlet 12, and the blowout opening 65B of the wind direction guide plate 60B is in the lateral direction. Therefore, almost all of the air blown from the second turbofan 50B hits the entire lower surface 20Bb of the heat exchanger 20B. In addition, although the lower wind force of the second turbofan 50B is stronger than the upper wind force, since the heat exchanger 20B is inclined, the lower side of the lower surface 20Bb of the heat exchanger 20B is from the second turbofan 50B. Since it becomes far, the wind pressure to the whole lower surface 20Bb of the heat exchanger 20B is almost averaged.

以上から、本実施例のダクト型空気調和機は、第１のターボファン５０Ａから熱交換器２０Ａの全面への風圧、第２のターボファン５０Ｂから熱交換器２０Ｂの全面への風圧が、それぞれ平均化されることから、熱交換効率が向上して、熱交換容量を大きくすることができ、このとき風量が少なくて済むから、ターボファン５０Ａ，５０Ｂを駆動するモータ３０を小型化できる。   From the above, in the duct type air conditioner of the present embodiment, the wind pressure from the first turbofan 50A to the entire surface of the heat exchanger 20A and the wind pressure from the second turbofan 50B to the entire surface of the heat exchanger 20B are respectively Since averaging is performed, the heat exchange efficiency can be improved and the heat exchange capacity can be increased. At this time, since the air volume is small, the motor 30 that drives the turbofans 50A and 50B can be downsized.

また、ターボファン５０Ａ，５０Ｂは薄型であり、モータ３０の上下方向に重なるように配置されており、しかも、熱交換器２０Ａ，２０Ｂは横からみてＶ字形状に配置されているので、筐体１０の薄型化、小型化が可能となる。   Further, the turbofans 50A and 50B are thin and are arranged so as to overlap with the vertical direction of the motor 30, and the heat exchangers 20A and 20B are arranged in a V shape when viewed from the side, so that the casing 10 can be reduced in thickness and size.

また、熱交換器２０Ａ，２０Ｂは横からみてＶ字形状に傾斜配置されていることから、縦配置した場合に比べて、熱交換器２０Ａ，２０Ｂの大面積化が可能となる。   Further, since the heat exchangers 20A and 20B are inclined and arranged in a V shape when viewed from the side, the heat exchangers 20A and 20B can have a larger area compared to the case where the heat exchangers 20A and 20B are arranged vertically.

なお、風向ガイド板６０Ａはその上面板に筐体１０の上面壁１０ａの一部を共用し、風向ガイド板６０Ｂはその下面板に筐体１０の下面に筐体１０の下面壁１０ｂの一部を共用したが、それぞれ独立して上面板、下面板を設けて、ターボファン５０Ａ，５０Ｂを囲むような箱型とすることもできる。   Note that the wind direction guide plate 60A shares a part of the upper surface wall 10a of the housing 10 with its upper surface plate, and the wind direction guide plate 60B has a lower surface plate with a lower surface of the housing 10 and a part of the lower surface wall 10b of the housing 10 as its lower surface plate. However, it is also possible to provide a box shape that surrounds the turbofans 50A and 50B by providing an upper surface plate and a lower surface plate independently of each other.
