It is sectional drawing of an indoor unit.

図２において、符号１１は２方向吹出形の天井埋込型空気調和機の室内機であり、この室内機１１は本体１２と化粧パネル１３とから構成されている。本体１２は天井板Ｔの開口部に装着され、建物から垂下した４本の吊りボルトａに吊下げ具ｂが固定されて天井空間に吊下げられている。   In FIG. 2, reference numeral 11 denotes an indoor unit of a two-way blowing type ceiling-embedded air conditioner. The indoor unit 11 includes a main body 12 and a decorative panel 13. The main body 12 is attached to the opening of the ceiling plate T, and a hanging tool b is fixed to four hanging bolts a hanging from the building and is suspended in the ceiling space.

前記化粧パネル１３は、中央に吸込口１４とこの吸込口１４の両端部に吹出口１５、１５とを有し、本体１２の底面に対して取り外し自在に設けられている。吸込口１４には複数の通気孔を有し、上側にエアフィルタ１６（図４参照）が配置された吸込グリル１７が取り付けられ、吹出口１５、１５には吹出方向を設定する風向調節器１８、１８が設けられている。   The decorative panel 13 has a suction port 14 at the center and air outlets 15 and 15 at both ends of the suction port 14, and is detachably provided on the bottom surface of the main body 12. A suction grille 17 having a plurality of ventilation holes and having an air filter 16 (see FIG. 4) disposed on the upper side is attached to the suction port 14, and a wind direction adjuster 18 that sets the blowing direction at the outlets 15 and 15. , 18 are provided.

図３、図４において、本体１２内には、前記吸込口１４及び吹出口１５、１５を連通する通風路２１が形成され、この通風路内２１には４つの熱交換器５ａ〜５ｄと、送風装置である２つのクロスフローファン２２、２２と、運転を制御する電装箱２３等が収納されている。   3 and 4, a ventilation passage 21 that communicates the suction port 14 and the blowout ports 15, 15 is formed in the main body 12. In the ventilation passage 21, four heat exchangers 5 a to 5 d and Two cross-flow fans 22 and 22 that are blowers and an electrical box 23 that controls operation are accommodated.

前記熱交換器５ａ〜５ｄは、２つの熱交換器５ａ、５ｂと２つの補助熱交換器５ｃ、５ｄであり、それぞれ横長板状の直方体をしている。熱交換器５ａ〜５ｂは略ハの字状（ほぼ左右対称）に設けられ、補助熱交換器５ｃ、５ｄは熱交換器５ａ、５ｂの吹出口１５側のほぼ上半分にわたって配置され、各熱交換器５ａ〜５ｄ間は、冷媒管でつながれている。これら熱交換器５ａ〜５ｄは、その長手方向が本体１２の長手方向に沿って設けられており、熱交換器５ａ、５ｂの一面は、吸込口１４に対して斜め下方に面するように配置され、熱交換器５ａ、５ｂの下縁部下方には熱交換器５ａ〜５ｄからのドレンを受けるためのドレンパン２４が配設される。熱交換器５ａ〜５ｄの吹出口１５側には前記２つのクロスフローファン２２、２２が配置されている。   The heat exchangers 5a to 5d are two heat exchangers 5a and 5b and two auxiliary heat exchangers 5c and 5d, each having a horizontally long rectangular parallelepiped shape. The heat exchangers 5a to 5b are provided in a substantially square shape (substantially left-right symmetrical), and the auxiliary heat exchangers 5c and 5d are arranged over substantially the upper half of the heat exchangers 5a and 5b on the outlet 15 side. The exchangers 5a to 5d are connected by a refrigerant pipe. These heat exchangers 5 a to 5 d are provided such that the longitudinal direction thereof is provided along the longitudinal direction of the main body 12, and one surface of the heat exchangers 5 a and 5 b is disposed so as to face obliquely downward with respect to the suction port 14.

The two cross flow fans 22 and 22 are arranged on the outlet 15 side of the heat exchangers 5a to 5d.

このように構成された空気調和機において、空調運転が開始されると、冷媒が冷凍回路を循環し、クロスフローファン２２、２２が運転される。これにより、破線矢印に示すように、室内の空気が吸込口１４から吸い込まれてエアフィルタ１６、熱交換器５ａ〜５ｄを通過する。熱交換器５ａ〜５ｄを通過するとき室内空気は熱交換され、熱交換された空気が吹出口１５、１５から室内へ吹き出されることにより室内が空調される。   In the air conditioner configured as described above, when the air conditioning operation is started, the refrigerant circulates through the refrigeration circuit, and the cross flow fans 22 and 22 are operated. Thereby, as shown by the broken line arrow, indoor air is sucked from the suction port 14 and passes through the air filter 16 and the heat exchangers 5a to 5d. When the air passes through the heat exchangers 5a to 5d, the indoor air is heat-exchanged, and the air subjected to the heat exchange is blown into the room through the air outlets 15 and 15, thereby air-conditioning the room.

ここで熱交換器に接続して設けられる除湿回路用部品について説明する。図５は熱交換器の底面図、図６は熱交換器の側面図である。図５、図６において、熱交換器５ａ〜５ｄは蛇行して配設された冷媒管に直交する複数の放熱フィン２５、２５・・を設けて作製され、各熱交換器５ａ〜５ｄの両端側には放熱フィン２５の幅と同じ幅寸法の管板２６、２６・・が設けられ、熱交換器５ａ〜５ｄの一方の端には冷媒の入口管２７と出口管２８が設けられている。熱交換器５ａ、５ｃと熱交換器５ｂ、５ｄとの間は、除湿回路用部品を介して連結されており、この除湿回路用部品は、ストレーナ７、キャピラリーチューブ８及び膨張弁６を有し、ストレーナ７及びキャピラリーチューブ８と膨張弁６とを並列に接続して構成したものである。キャピラリーチューブ８はＵ字状に折曲加工され、このキャピラリーチューブ８とストレーナ７は、冷媒管２９にて直線状に形成されている。そして除湿回路用部品は、熱交換器５ｂの空気流出側（吹出口側）で補助熱交換器５ｄの斜め下方に配置され、熱交換器５ｂの横幅いっぱいにわたり、かつ補助熱交換器５ｄの空気流出側放熱フィン２５の先端より低く設けられている。つまり、補助熱交換器５ｄの厚さ寸法（放熱フィンの幅寸法）より低くして設けられている。除湿回路用部品は熱交換器５ｂに対してパテ３１で押えて固定されている。   Here, the dehumidifying circuit component provided in connection with the heat exchanger will be described. FIG. 5 is a bottom view of the heat exchanger, and FIG. 6 is a side view of the heat exchanger. 5 and 6, the heat exchangers 5 a to 5 d are made by providing a plurality of heat radiation fins 25, 25... Orthogonal to a refrigerant pipe arranged meandering, and both ends of each of the heat exchangers 5 a to 5 d. Tube plates 26, 26,... Having the same width as the radiating fins 25 are provided on the side, and refrigerant inlet pipes 27 and outlet pipes 28 are provided at one ends of the heat exchangers 5a to 5d. . The heat exchangers 5a and 5c and the heat exchangers 5b and 5d are connected via dehumidification circuit components. The dehumidification circuit components include a strainer 7, a capillary tube 8, and an expansion valve 6. The strainer 7 and the capillary tube 8 and the expansion valve 6 are connected in parallel. The capillary tube 8 is bent into a U shape, and the capillary tube 8 and the strainer 7 are linearly formed by a refrigerant tube 29. The dehumidifying circuit component is disposed obliquely below the auxiliary heat exchanger 5d on the air outflow side (blower side) of the heat exchanger 5b, covers the entire width of the heat exchanger 5b, and the air of the auxiliary heat exchanger 5d. It is provided lower than the tip of the outflow side radiation fin 25. That is, the auxiliary heat exchanger 5d is provided to be lower than the thickness dimension (the width dimension of the radiation fin). The dehumidifying circuit component is fixed to the heat exchanger 5b by pressing with a putty 31.

このようにキャピラリーチューブ８、ストレーナ７及びパテ３１で構成された除湿回路用部品を補助熱交換器５ｄの下方に配置することにより、熱交換器５ｂの下部を通過する部分の空気量が除湿回路用部品７、８、３１に遮られて少なくなり、熱交換器５ｂ上部の補助熱交換器５ｄと重なり合う部分を通過する空気量が多くなる。これにより、熱交換器５ｂ、５ｄに対して空気量が適度に配分されて熱交換効率を向上させることができる。   Thus, by arranging the dehumidifying circuit component composed of the capillary tube 8, the strainer 7 and the putty 31 below the auxiliary heat exchanger 5d, the amount of air passing through the lower portion of the heat exchanger 5b is reduced. The amount of air passing through the portion overlapping with the auxiliary heat exchanger 5d above the heat exchanger 5b increases. Thereby, the amount of air is appropriately distributed to the heat exchangers 5b and 5d, and the heat exchange efficiency can be improved.

また、従来のように、熱交換器５ａ〜５ｄの真横に配置した除湿回路用部品７、８、３１を熱交換器５ｂの通風路側（空気流出側）に設けたことにより、熱交換器５ａ〜５ｄを、従来の通風路２１の外側であり熱交換器５ａ〜５ｄの真横側へ拡張して熱交換器５ａ〜５ｄの大型化をし、熱交換効率の向上を図ることができる。   Further, as in the prior art, by providing the dehumidifying circuit parts 7, 8, and 31 arranged just beside the heat exchangers 5a to 5d on the ventilation path side (air outflow side) of the heat exchanger 5b, the heat exchanger 5a ˜5d can be expanded to the outside of the conventional ventilation path 21 and directly to the side of the heat exchangers 5a to 5d to increase the size of the heat exchangers 5a to 5d, thereby improving the heat exchange efficiency.

以上、一実施例に基づいて本発明を説明したが、本発明は、これに限定されるものではなく、要旨を逸脱しない範囲内で変形可能である。   As mentioned above, although this invention was demonstrated based on one Example, this invention is not limited to this, It can deform | transform within the range which does not deviate from a summary.
