The purpose is to

(Means for Solving the Problems) The present invention provides an integrated air conditioner having heat dissipation components, in which the heat dissipation components are placed in a component storage box provided at the boundary between an outdoor ventilation path and an indoor ventilation path. A heat dissipating portion formed on the outer surface of the parts storage box is arranged in the outdoor ventilation passage, and the inside of the parts storage box is communicated with the air introduction side of the indoor ventilation passage. .
(作用)
冷房運転時には、部品収納箱の放熱部が室外通
風路を流れる室外空気に接触するとともに、部品
収納箱内の要放熱部品が室内通風路に導入される
室内空気に接触する。(Function) During cooling operation, the heat radiating portion of the parts storage box comes into contact with the outdoor air flowing through the outdoor ventilation path, and the heat radiation-required components in the parts storage box come into contact with the indoor air introduced into the indoor ventilation path.
したがつて、要放熱部品の放熱作用が室外空気
と室内空気の2つの手段で実行されるため、外気
温が低ければ室外空気と室内空気の両方で、また
外気温が高い場合には室内空気によつて効果的な
放熱作用が得られ、負荷変動による影響もあまり
受けることがない。 Therefore, the heat dissipation effect of the heat dissipating components is carried out by two means: outdoor air and indoor air, so if the outdoor temperature is low, both outdoor air and indoor air are used, and when the outdoor temperature is high, the indoor air is used. This provides an effective heat dissipation effect and is not significantly affected by load fluctuations.
また、要放熱部品からの全放熱量が常時室内空
気に放出されるものではないから、冷房性能の低
下も少なく、快適性が損われるおそれもない。 Furthermore, since the entire amount of heat radiated from the heat radiating components is not always released into the indoor air, there is little deterioration in cooling performance and there is no fear that comfort will be impaired.

分の内側面に接触させて取付けている。 As shown in FIGS. 1 and 2, a heat insulating wall 22 curved in an S-shape inside a vertically long box-shaped case 21
It is divided into an outdoor side and an indoor side. An outdoor ventilation path 23 is formed along the heat insulating wall 22 on the outdoor side of the case 21, and an outdoor blower 24 and an outdoor heat exchanger 25 are installed in this outdoor ventilation path 23. In addition, the indoor side of the case 21 has a drain tray 2.
6 or the like, and the upper space along the heat insulating wall 22 is used as an indoor ventilation path 27, and an indoor blower 28 and an outdoor heat exchanger 29 are installed inside the indoor ventilation path 27. A vertically long thin box-shaped component storage box 30 is fixed in the lower space on the indoor side of the case 21 along the heat insulating wall 22, and components 31 that require heat dissipation such as a frequency converter are stored in this component storage box 30. There is. Parts storage box 3
A large number of fins 32 are formed on the outer surface of the side wall on the heat insulating wall 22 side of No. ing. Further, the component storage box 30 is open at the top and bottom, and communicates with the indoor ventilation passage 27 and the indoor air inlet 34 provided at the bottom of the case 21 through the openings. It should be noted that among the components 31 requiring heat dissipation, the one 31a that requires a large amount of heat dissipation is attached in contact with the inner surface of the fin 32 portion of the component storage box 30.
このような構成によれば、冷房運転時には部品

行なわれる。 According to such a configuration, the fins 32 provided in the parts storage box 30 are connected to the outdoor ventilation path 23 during cooling operation.
comes into contact with the indoor air flowing as shown by arrow a, and heat is radiated through the fins 32 through the component storage box 30 and the heat radiating components 31 stored therein. Particularly, since the cooling component 31a which requires a large amount of heat radiation is brought into contact with the inner surface of the component storage box at the fin 32 portion, the heat radiation effect is efficiently performed.

ため、室内空気よつても放熱作用が行なわれる。

効率よく冷却される。なお、放熱作用は室内外空

熱負荷はそれだけ減少し、冷房能力の低下は抑制
される。 Also, during operation, the indoor air introduced from the indoor air intake port 34 passes through the parts storage box 30 as shown by arrow b and is guided to the indoor ventilation path 27, and this indoor air flows into the parts storage box 30 that requires heat dissipation. Since it comes into contact with the component 31, heat is also radiated from the indoor air.
During cooling, the indoor air temperature is low, so this heat dissipation effect is effective, and the heat dissipation components 31 are efficiently cooled with a small amount of indoor air. Note that, since the heat dissipation effect is performed by both indoor and outdoor air means, the heat dissipation load due to the indoor air is reduced accordingly, and a decrease in cooling capacity is suppressed.

の空気調和機に比べて小さく、それだけ信頼性も
向上できる。 Of course, when the outside temperature is high, such as during a cooling overload, the amount of heat radiated to the indoor air increases, but even in this case, the cooling capacity of the air conditioner shown in Figure 3, which introduces outdoor air, can be significantly increased. Moreover, as shown in FIG. 4, there is no fear that the heat dissipation effect of the heat dissipation components becomes insufficient because it depends only on the outdoor air. In this sense, the influence of load fluctuations is smaller than with conventional air conditioners, and reliability can be improved accordingly.
なお、室内外空気の両方を放熱作用に用いるも
のでありながらも、部品収納箱30が両空気通路
23,27の仕切りを兼ね、室外空気による放熱
作用は伝熱によるものであるため、両空気通路は
確実に遮蔽され、シール性が確実に保持でき、騒
音の侵入防止にも有効である。 Although both indoor and outdoor air are used for heat dissipation, the component storage box 30 also serves as a partition between both air passages 23 and 27, and the heat dissipation effect of outdoor air is due to heat transfer. The passageway is reliably shielded, sealing properties are reliably maintained, and it is also effective in preventing noise from entering.
また、構成が簡単で、制作も容易に行なえ、特
にコスト高を招く部分もなく、安価に提供できる
利点も得られる。 In addition, the structure is simple, the production is easy, there are no parts that cause high costs, and the product can be provided at low cost.

As described above, according to the present invention, it is possible to efficiently perform heat dissipation cooling of components that require heat dissipation by effectively utilizing both outdoor air and indoor air, and a sufficient heat dissipation effect can be obtained even when the outside temperature is high. In addition, effects such as maintaining comfort can be achieved without reducing the cooling capacity.
