しかし、室外機に配設される消費電力の大きな圧縮機の運転にソーラーパネルで発電される電力を使用する場合に必要な前記コンバータが必要となるが、このコンバータは発熱するので冷却する必要がある。   However, the converter required when using the power generated by the solar panel for the operation of the compressor with large power consumption disposed in the outdoor unit is necessary. However, since this converter generates heat, it needs to be cooled. is there.

そこで本発明は、ソーラーパネルで発電された直流の電圧を昇圧するＤＣ−ＤＣコンバータを搭載したプリント基板を電装箱に内蔵した場合でも、前記ＤＣ−ＤＣコンバータを冷却できるようにすることを目的とする。   Therefore, the present invention has an object to enable cooling of a DC-DC converter even when a printed circuit board equipped with a DC-DC converter that boosts a DC voltage generated by a solar panel is incorporated in an electrical box. To do.

このため第１の発明は、室内機と、圧縮機や凝縮機及び凝縮機冷却用送風機などを有する室外機とを備え、ソーラーパネルで発電される電力を使用可能な空気調和装置において、前記室外機の裏面に前記ソーラーパネルで発電された直流の電圧を昇圧するＤＣ−ＤＣコンバータを搭載したプリント基板を内蔵した電装箱を固定すると共に、前記電装箱の両側面には空気流通孔を開設したことを特徴とする。   Therefore, the first invention includes an indoor unit and an outdoor unit having a compressor, a condenser, a condenser cooling fan, and the like, and is an air conditioner capable of using electric power generated by a solar panel.

このように、パネル脚固定具１０、１０が室外機１の両側板１３、１３に固定された後、パネル脚固定具１０、１０の上部をソーラーパネル部１２に固定したパネル支持具１１、１１の差込み部３０に差し込んだ状態で、パネル脚固定具１０、１０とパネル支持具１１、１１とを固定するので、パネル脚固定具１０、１０が室外機１に堅固に固定される。   As described above, after the panel leg fixtures 10 and 10 are fixed to the side plates 13 and 13 of the outdoor unit 1, the panel support fixtures 11 and 11 in which the upper portions of the panel leg fixtures 10 and 10 are fixed to the solar panel portion 12. Since the panel leg fixtures 10 and 10 and the panel support fixtures 11 and 11 are fixed in a state where the panel leg fixtures 10 and 10 are inserted into the insertion portion 30, the panel leg fixtures 10 and 10 are firmly fixed to the outdoor unit 1.

また、以上のようにパネル脚固定具１０、１０、パネル支持具１１、１１及びソーラーパネル部１２が固定されると、本出願人の実験によれば、風速５０メートルの風を室外機１に当てても、パネル支持具１１、１１やパネル脚固定具１０、１０が折れ曲がることなく、破損することもなかった。   In addition, when the panel leg fixtures 10 and 10, the panel supports 11 and 11, and the solar panel unit 12 are fixed as described above, according to the experiment conducted by the present applicant, the wind at a wind speed of 50 meters is applied to the outdoor unit 1. Even if it hits, the panel support tools 11 and 11 and the panel leg fixing tools 10 and 10 did not bend and were not damaged.

このように固定する場合、ソーラーパネル部１２及びパネル支持具１１、１１を受光面１２Ａが室外機１の正面側斜め上方に向けられ、水平に対して１５度〜４０度の範囲で変更調整できるものである。   When fixing in this way, the solar panel 12 and the panel supports 11 and 11 can be changed and adjusted in a range of 15 to 40 degrees with respect to the horizontal, with the light receiving surface 12A directed obliquely upward on the front side of the outdoor unit 1. Is.

従って、空気調和装置１のパネル装置２は、正面を太陽光の入射する方角（北向きを除く方角）に向けて設置する。次に、角度指示ラベル３５の表示に従ってパネル支持具１１、１１を調整ねじ３４及び支点軸３１を緩めると支点軸３１を中心として回動させることができ、受光面１２Ａの傾斜角度（１５度〜４０度の範囲）を調整する。この調整後、調整ねじ３４及び支点軸３１で締め付けることにより、受光面１２Ａにより多くの太陽光を取り入れることができる。   Therefore, the panel apparatus 2 of the air conditioning apparatus 1 is installed with its front facing in the direction in which sunlight is incident (the direction excluding the north direction). Next, when the adjustment screws 34 and the fulcrum shaft 31 are loosened according to the display of the angle instruction label 35, the panel supports 11 and 11 can be rotated around the fulcrum shaft 31, and the inclination angle of the light receiving surface 12A (15 degrees to The range of 40 degrees). After this adjustment, by tightening with the adjustment screw 34 and the fulcrum shaft 31, more sunlight can be taken into the light receiving surface 12A.

４０はソーラーパネル２Ａで発電された直流の電圧を昇圧するＤＣ−ＤＣコンバータや比較回路などを含むパワーコントローラ４１などが搭載されたプリント基板を内蔵した電装箱で、直方体形状を呈した左右の両側面には複数の空気流通孔４２が開設されている。   40 is an electrical box with a built-in printed circuit board on which a DC-DC converter that boosts the DC voltage generated by the solar panel 2A and a power controller 41 including a comparison circuit are mounted. A plurality of air circulation holes 42 are formed on the surface.

そして、この電装箱４０は室外機体の裏面の取付板５上に、この電装箱４０の取付側の面が取付板５の上部周縁に突設した突部５Ａにより取付板５の平面部５Ｂと少し間隔Ｓを存した状態で上部及び下部の取付片３９（下部の取付片は図示せず）に開設した取付孔を介してねじ４３により固定される。   The electrical box 40 is connected to the flat surface portion 5B of the mounting plate 5 by a projection 5A on the mounting plate 5 on the back surface of the outdoor unit and the mounting side surface of the electrical box 40 projecting from the upper periphery of the mounting plate 5. It is fixed with screws 43 through mounting holes formed in the upper and lower mounting pieces 39 (the lower mounting pieces are not shown) with a slight spacing S.

この場合、前記電装箱４０の一部はその上部において取付板５の突部５Ａと接して、また電装箱４０の下端に形成した間隔子４４により、前述したように、電装箱４０の取付側の面が取付板５の平面部５Ｂと少し間隔Ｓを存した状態で室外機体の取付板５に固定される。これにより、取付板５（室外機体）から電装箱４０への熱伝導が極力減少される。   In this case, as described above, a part of the electrical box 40 is in contact with the protrusion 5A of the mounting plate 5 at the upper portion thereof and the spacing element 44 formed at the lower end of the electrical box 40, as described above. Is fixed to the mounting plate 5 of the outdoor unit with a slight gap S from the flat portion 5B of the mounting plate 5. Thereby, the heat conduction from the mounting plate 5 (outdoor unit) to the electrical equipment box 40 is reduced as much as possible.

なお、前記突部５Ａは平面視コ字形状に形成されているが、この形状に限らず、前記電装箱４０と取付板５との接触面積が小さければ、熱伝導が極力減少するものであるから、種々の実施形態が想定される。例えば、突部を点在させるようにして、接触面積を小さくしてもよい。   The protrusion 5A is formed in a U shape in plan view. However, the shape is not limited to this shape. If the contact area between the electrical box 40 and the mounting plate 5 is small, heat conduction is reduced as much as possible. Thus, various embodiments are envisaged. For example, the contact area may be reduced by interspersing the protrusions.

また、電装箱４０の一部が吸込用パネル７の吸込口６上に跨るように配設して固定する。このため、駆動モータにより送風機４が運転すると吸込用パネル７の吸込口６を介して室外機体内に空気が導入されて凝縮機３を冷却して熱交換された空気が室外機体の前面の吹出口８より前方へ排気される際に、電装箱４０の外方の側面の空気流通孔４２から該電装箱４０内に空気が流入した後、内方の側面の空気流通孔４２を介して、前述したように、吸込用パネル７の吸込口６を介して室外機体内へ導入されることによりＤＣ−ＤＣコンバータを含むパワーコントローラ４１やプリント基板が冷却されるばかりか、吸込用パネル７の吸込口６へと空気が導入される際に電装箱４０自体も冷却されることとなる。   Further, a part of the electrical box 40 is disposed and fixed so as to straddle the suction port 6 of the suction panel 7. For this reason, when the blower 4 is operated by the drive motor, air is introduced into the outdoor unit through the suction port 6 of the suction panel 7 to cool the condenser 3 and heat exchange is performed on the front surface of the outdoor unit. When the air is exhausted forward from the outlet 8, air flows into the electrical box 40 from the air flow hole 42 on the outer side surface of the electrical box 40, and then passes through the air flow hole 42 on the inner side surface. As described above, the power controller 41 including the DC-DC converter and the printed circuit board are cooled by being introduced into the outdoor unit through the suction port 6 of the suction panel 7, and the suction of the suction panel 7. When air is introduced into the mouth 6, the electrical box 40 itself is also cooled.

従って、発熱するＤＣ−ＤＣコンバータを含むパワーコントローラ４１を初めとして、それが搭載されるプリント基板や電装箱４０も冷却されることとなる。   Accordingly, the printed circuit board and the electrical box 40 on which the power controller 41 including the DC-DC converter that generates heat is mounted are also cooled.

次に、図７の本空気調和装置の制御ブロック図に基づいて、説明する。５０は空気調和装置の室内機で、種々の制御に係る電子部品が搭載されたプリント基板５１を内蔵する。そして、このプリント基板５１と家屋の壁面の外側に配設される換気装置である吸排気装置５２とはリレーのスイッチ５３を介在するＤＣ１２ボルトの電線５４や電線５５などにより接続されている。なお、この吸排気装置５２は、外気を導入して室内に供給可能であり、また逆に室内の汚れた空気を室外に排気可能である。   Next, it demonstrates based on the control block diagram of this air conditioning apparatus of FIG. Reference numeral 50 denotes an indoor unit of an air conditioner, which includes a printed circuit board 51 on which electronic components related to various controls are mounted. The printed circuit board 51 and the intake / exhaust device 52, which is a ventilation device disposed outside the wall surface of the house, are connected to each other by a DC12-volt electric wire 54, an electric wire 55, or the like with a relay switch 53 interposed therebetween. In addition, this intake / exhaust device 52 can introduce outside air and supply it indoors, and conversely, can exhaust dirty air inside the room to the outside.

そして、ソーラーパネル２Ａからの電圧がＤＣ１２ボルト以上になると、電線６３を介して室内機５０のプリント基板５１に電力を供給して電線５５を介して吸排気装置５２を運転可能とする。一方、ＤＣ１２ボルト未満の場合には、単相１００ボルトの商用電源を通してプリント基板５１でＤＣ１２ボルトが作られる。そして、スイッチ５３が閉じることにより、ＤＣ１２ボルトの電力が供給され、吸排気装置５２を運転可能とする。   When the voltage from the solar panel 2 </ b> A becomes DC 12 volts or more, electric power is supplied to the printed circuit board 51 of the indoor unit 50 via the electric wire 63 so that the intake / exhaust device 52 can be operated via the electric wire 55. On the other hand, if the voltage is less than 12 volts DC, 12 volts DC is produced by the printed circuit board 51 through a single-phase 100-volt commercial power supply. When the switch 53 is closed, DC 12 volt power is supplied, and the intake / exhaust device 52 can be operated.

また、室内機５０のプリント基板５１は室外機１に内蔵されるプリント基板５６に搭載される整流平滑回路５７にリレーのスイッチ５８を介在する単相１００ボルトの電線５９及び信号線６０、６０などにより接続されている。６１はインバータ回路で、直流を交流に変換して圧縮機６２を駆動するための電源回路である。   Further, the printed circuit board 51 of the indoor unit 50 includes a single-phase 100-volt electric wire 59 and signal lines 60 and 60 that have a relay switch 58 interposed in a rectifying and smoothing circuit 57 mounted on a printed circuit board 56 built in the outdoor unit 1. Connected by. 61 is an inverter circuit which is a power supply circuit for driving the compressor 62 by converting direct current into alternating current.

そして、ソーラーパネル２Ａからの電圧をパワーコントローラ４１に含まれるＤＣ−ＤＣコンバータが昇圧して、比較回路によりＤＣ３００ボルト以上になった場合には、電線６４を介して室外機１のプリント基板５６に電力を供給してインバータ回路６１により直流を交流に変換して消費電力が大きい圧縮機６２を運転可能とする
一方、ＤＣ３００ボルト未満の場合には、単相１００ボルトの商用電源を整流平滑回路５７により平滑整流し昇圧しＤＣ２８０ボルトに変換する。そして、スイッチ５８が閉じることにより、インバータ回路６１へＤＣ２８０ボルトの電力が供給され、インバータ回路６１により直流から交流に変換して圧縮機６２を運転可能とする。 When the DC-DC converter included in the power controller 41 boosts the voltage from the solar panel 2A and becomes equal to or higher than DC 300 volts by the comparison circuit, the voltage is applied to the printed circuit board 56 of the outdoor unit 1 via the electric wire 64. Electric power is supplied, and direct current is converted into alternating current by the inverter circuit 61 so that the compressor 62 with large power consumption can be operated. Smoothed rectified, boosted and converted to DC 280 volts. When the switch 58 is closed, DC 280 volt power is supplied to the inverter circuit 61, and the inverter circuit 61 converts the direct current into the alternating current so that the compressor 62 can be operated.

なお、ソーラーパネル２Ａで発電される電力を室外機１においては、圧縮機６２の運転に利用するようにしたが、同じく室外機１内に配設される送風機４の駆動モータの運転に利用してもよいし、室内機５０においては吸排気装置５２の駆動源に限らず、室内機５０における全て電力を利用するものに利用してもよい。   The electric power generated by the solar panel 2A is used in the operation of the compressor 62 in the outdoor unit 1, but is also used in the operation of the drive motor of the blower 4 disposed in the outdoor unit 1. Alternatively, the indoor unit 50 is not limited to the drive source of the intake / exhaust device 52, but may be used for all the units that use electric power in the indoor unit 50.
