Description

本発明は、空気調和機の室外機に係り、特に、複数の室外熱交換器を連結させて一体型に構成した空調室外機に関するものである。   The present invention relates to an outdoor unit of an air conditioner, and more particularly to an air-conditioning outdoor unit configured integrally by connecting a plurality of outdoor heat exchangers.

一般に空気調和装置は、屋外に配置される室外機と、室内に配置される室内機とを備えており、室外機及び室内機のそれぞれの内部に設けられた熱交換器により熱交換を行い、室内の冷暖房を行っている。そして、ビルや工場等に適用される空気調和装置は、大きな空調能力が求められるため、必然的に室外機の規模も大きくなってしまう。   In general, an air conditioner includes an outdoor unit arranged outdoors and an indoor unit arranged indoors, and performs heat exchange with heat exchangers provided in each of the outdoor unit and the indoor unit. The room is air-conditioned. And since the air conditioning apparatus applied to a building, a factory, etc. needs a big air conditioning capability, the scale of an outdoor unit will necessarily become large.

こういった大型の室外機では、プロペラファンを室外ユニット上端に配置し、室外ユニット背面から吸い込んだ空気を上方へ吹出す形態をとることが多いが、このような形態では、効率的な熱交換を実現するためにできる限り、プロペラファン近傍にのみかつプロペラファンに対して水平あるいはそれに準ずる形態で熱交換器を配置していた。しかし、上述の形態では、熱交換性能の向上のために室外ユニット設置面積を拡大させる必要がある。そこで、熱交換器をコの字形形態にすることで、限られた設置スペースの中で熱交換器容量（面積）を拡張することが必要になってくる。   In such a large outdoor unit, a propeller fan is arranged at the upper end of the outdoor unit and the air sucked from the back of the outdoor unit is often blown upward, but in such a form, efficient heat exchange is performed. In order to realize the above, the heat exchanger is arranged only in the vicinity of the propeller fan and in a form horizontal to or equivalent to the propeller fan. However, in the above-described embodiment, it is necessary to increase the outdoor unit installation area in order to improve the heat exchange performance. Therefore, it becomes necessary to expand the heat exchanger capacity (area) in a limited installation space by adopting a U-shaped heat exchanger.

従来技術としては、室外機の大型化を抑制しつつ熱交換性能を向上できる空気調和機の室外機を得ることを目的として、予め複数の室外機を互いに連結させた一体型室外機において、各室外機のプロペラファンをそれぞれ囲うように略コの字形の水平断面を有する熱交換器を、筐体背面に沿って複数個配置し、熱交換器における筐体側面側に位置する部分を筐体中央側に位置する部分よりも筐体正面に向かって長く構成した室外機が知られている（例えば、特許文献１）。   As a conventional technique, in order to obtain an outdoor unit of an air conditioner that can improve heat exchange performance while suppressing an increase in the size of the outdoor unit, A plurality of heat exchangers having a substantially U-shaped horizontal cross section are arranged along the back of the casing so as to surround the propeller fan of the outdoor unit, and the portion located on the side of the casing in the heat exchanger is the casing. An outdoor unit configured to be longer toward the front of the housing than a portion located on the center side is known (for example, Patent Document 1).

特開２００８−１３８９５１（［００１０］段落、図１）JP2008-138951 ([0010] paragraph, FIG. 1)

しかし、特許文献１に開示された技術では、２台の室外機を隣接させた構成をしている。すなわち、それぞれの室外機にファン、熱交換器、圧縮機やアキュムレータ等の冷媒サイクルを構成する機器が設置され、熱交換器は、それぞれのファンを囲むように、筐体の左右両側面及び背面に沿って、略コの字形の水平断面形状に構成されている。そして、熱交換器と冷媒サイクルとは、一方は筐体の側面側、他方は筐体の中央側にて接続されている。   However, the technique disclosed in Patent Document 1 has a configuration in which two outdoor units are adjacent to each other. That is, each outdoor unit is provided with a device that constitutes a refrigerant cycle such as a fan, a heat exchanger, a compressor, and an accumulator, and the heat exchanger surrounds the respective fans on both the left and right side surfaces and the rear surface. Is formed in a substantially U-shaped horizontal cross-sectional shape. One of the heat exchanger and the refrigerant cycle is connected to the side of the casing, and the other is connected to the center of the casing.

ところで、複数のファンが並設されている場合、筐体内に流入する空気の風速は、筐体の側面側で速く、２つのファンの中間にあたる筐体の中央側で遅い。また、一般に、熱交換器の熱交換効率は、熱交換器を通過する空気の風速が速い方が高効率となる。   By the way, when a plurality of fans are arranged in parallel, the wind speed of the air flowing into the housing is fast on the side surface side of the housing, and is slow on the center side of the housing, which is between the two fans. In general, the heat exchange efficiency of the heat exchanger is higher when the wind speed of the air passing through the heat exchanger is faster.

従って、従来技術では、一方の熱交換器では、風速の速い筐体の側面側で冷媒の出入が行われ、他方の熱交換器では、風速の遅い筐体の中央側で冷媒の出入が行われることになってしまい、２つの熱交換器の間で熱交換性能が異なってしまうことになる。このように左右の熱交換器の間で熱交換性能が異なってしまうため、熱交換効率が低下してしまうという問題があり、また、２つの熱交換器の熱交換性能を同一とするためには、冷媒分配を行わなければならないという問題があった。   Therefore, in the prior art, in one heat exchanger, the refrigerant enters and exits on the side surface side of the casing with a high wind speed, and in the other heat exchanger, the refrigerant enters and exits on the center side of the casing with a low wind speed. The heat exchange performance will be different between the two heat exchangers. Since the heat exchange performance differs between the left and right heat exchangers in this way, there is a problem that the heat exchange efficiency is lowered, and in order to make the heat exchange performance of the two heat exchangers the same However, there was a problem that refrigerant distribution had to be performed.

この発明は、上記のような課題を解決するためになされたもので、複数の室外熱交換器を連結させて一体型に構成した空調室外機において、左右の熱交換器間で冷媒分配を不要とし、熱交換効率の高い空気調和機の室外機を提供することを目的とする。   The present invention has been made to solve the above-described problems, and in an air-conditioning outdoor unit configured integrally by connecting a plurality of outdoor heat exchangers, refrigerant distribution is not required between the left and right heat exchangers. And it aims at providing the outdoor unit of an air conditioner with high heat exchange efficiency.

本発明に係る空気調和機の室外機は、両側面及び背面に空気吸込口を有するとともに、上面に２つの空気吹出口が並設された筐体と、前記空気吹出口のそれぞれに配置され、前記空気吸込口から空気を吸込み、前記空気吹出口から空気を吹出すファンと、前記筐体内で開口が正面を向くようにそれぞれ設置された２つのコの字型の熱交換器と、前記筐体内に設置され、前記２つのコの字型の熱交換器と接続されて冷媒を循環させる冷媒配管と、前記冷媒配管内を流れる前記冷媒を圧縮する圧縮機と、前記ファン又は前記圧縮機を制御する制御部と、を備えた空調室外機において、前記２つのコの字型の熱交換器の一方の側には前記圧縮機が設置され、他方の側には前記制御部が設置されたことを特徴とするものである。 The outdoor unit of the air conditioner according to the present invention has air suction ports on both side surfaces and the back surface, and is disposed in each of the air blow port and a housing in which two air blow ports are arranged in parallel on the top surface, A fan that sucks air from the air inlet and blows air out of the air outlet, two U-shaped heat exchangers installed such that the opening faces the front in the casing, and the housing A refrigerant pipe installed in the body and connected to the two U-shaped heat exchangers to circulate the refrigerant; a compressor that compresses the refrigerant flowing in the refrigerant pipe; and the fan or the compressor. An air conditioner outdoor unit having a control unit for controlling, the compressor is installed on one side of the two U-shaped heat exchangers, and the control unit is installed on the other side it is shall be and characterized.

本発明によれば、複数の室外熱交換器を連結させて一体型に構成した空調室外機において、左右の熱交換器間で冷媒分配を不要とし、熱交換効率の高い空気調和機の室外機を得ることができる。   According to the present invention, in an air conditioning outdoor unit configured integrally by connecting a plurality of outdoor heat exchangers, it is unnecessary to distribute refrigerant between the left and right heat exchangers, and the outdoor unit of an air conditioner having high heat exchange efficiency Can be obtained.

実施の形態１．
図１は、実施の形態１に係る空調室外機の正面断面図であり、同じく図２は上面平面図、図３は図１のＡ−Ａ線による断面図である。 Embodiment 1 FIG.
1 is a front cross-sectional view of an air-conditioning outdoor unit according to Embodiment 1, FIG. 2 is a top plan view, and FIG. 3 is a cross-sectional view taken along line AA of FIG.

図１及び図２において、空調室外機の筐体１の上方には、２つの空気吹出口１０が筐体１の幅方向に並設して開口しており、それぞれの空気吹出口１０には、空気吹出口１０の中心に回転軸を持つ室外ファン２が配設されている。また、筐体１の左右両側面及び背面は、図示していないがほぼ全面にわたって空気吸込口が形成されており、室外ファン２が回転することにより、空気吸込口から空気が吸い込まれ、空気吹出口１０から吹出される空気の流れが発生するように構成されている。   In FIG.1 and FIG.2, two air blower outlets 10 are arranged in parallel and opened in the width direction of the housing | casing 1 above the housing | casing 1 of an air-conditioning outdoor unit. An outdoor fan 2 having a rotation shaft is disposed at the center of the air outlet 10. The left and right side surfaces and the rear surface of the housing 1 are not shown in the drawing, but air suction ports are formed over almost the entire surface. When the outdoor fan 2 rotates, air is sucked from the air suction ports, A flow of air blown from the outlet 10 is generated.

また、図１乃至図３において、それぞれの空気吹出口１０の下方には熱交換器３が設けられている。熱交換器３は、筐体１の左右両側面及び背面に沿うように設けられており、平面視においてそれぞれの空気吹出口１０を略コの字型に囲むように設けられている。なお、熱交換器３は、筐体１の中央側で筐体１の内部に向けて折り曲げられているが、その内部に向けて折り曲げられた部分の長さは、側面側の長さに比べて短くなっている。また、面Ｃは２つの空気吹出口１０の間を２分する面であって、熱交換器３は、面Ｃに対して対称に設けられている。熱交換器３が設けられていない正面側からは、筐体１の内部に設置された機器のメンテナンスを行う。   1 to 3, a heat exchanger 3 is provided below each air outlet 10. The heat exchanger 3 is provided along both the left and right side surfaces and the back surface of the housing 1, and is provided so as to surround each air outlet 10 in a substantially U shape in plan view. The heat exchanger 3 is bent toward the inside of the casing 1 on the center side of the casing 1, but the length of the portion bent toward the inside is larger than the length on the side surface side. Is getting shorter. Further, the surface C is a surface that bisects between the two air outlets 10, and the heat exchanger 3 is provided symmetrically with respect to the surface C. From the front side where the heat exchanger 3 is not provided, maintenance of equipment installed inside the housing 1 is performed.

また、熱交換器３には、図示していないが、冷媒が流れる配管と、熱交換面積を大きくするためのフィンとが設けられており、筐体１の空気吸込口から筐体１内部に流入する空気が熱交換器３を通過することにより、熱交換器３内に配設された配管内を流れる冷媒との間で熱交換が可能な構成になっている。また、この図示しない配管は、熱交換器３内を水平方向に往復するように配設されており、後述するヘッダ管６に接続されている。そして、図示しないフィンは、この配管に対して垂直に形成されている。   In addition, although not shown, the heat exchanger 3 is provided with a pipe through which the refrigerant flows and fins for increasing the heat exchange area. From the air suction port of the housing 1 to the inside of the housing 1. When the inflowing air passes through the heat exchanger 3, heat exchange can be performed with the refrigerant flowing in the piping disposed in the heat exchanger 3. The pipe (not shown) is arranged so as to reciprocate in the heat exchanger 3 in the horizontal direction, and is connected to a header pipe 6 described later. And the fin which is not shown in figure is formed perpendicularly | vertically with respect to this piping.

また、筐体１内には、圧縮機４、アキュムレータ５、ヘッダ管６及び熱交換器３が、図中実線にて模式的に示した冷媒配管によって接続されて、冷媒回路が構成されている。ヘッダ管６は、熱交換器３ごとに設けられており、熱交換器３の上下方向の冷媒量を適正に分配する。また、ヘッダ管６は、それぞれの熱交換器３において、他方の熱交換器３に近い方の端部（以降、近接端部と略記する）に設けられている。   In the housing 1, a compressor 4, an accumulator 5, a header pipe 6, and a heat exchanger 3 are connected by a refrigerant pipe schematically shown by a solid line in the drawing to constitute a refrigerant circuit. . The header pipe 6 is provided for each heat exchanger 3 and appropriately distributes the amount of refrigerant in the vertical direction of the heat exchanger 3. In addition, the header pipe 6 is provided in each heat exchanger 3 at an end portion closer to the other heat exchanger 3 (hereinafter abbreviated as a proximity end portion).

ヘッダ管６は、熱交換器３の冷媒入口側と冷媒出口側とにそれぞれ設けられている。そして、熱交換器３内の配管は、一端が冷媒入口側のヘッダ管６に接続され、他端が冷媒出口側のヘッダ管６に接続されている。なお、図中Ｂで示したのは、図示しない室内機への接続を意味しており、すなわち、図示しない室内機からの冷媒配管は、ヘッダ管６、及びアキュムレータ５に接続されている。   The header pipes 6 are respectively provided on the refrigerant inlet side and the refrigerant outlet side of the heat exchanger 3. The pipe in the heat exchanger 3 has one end connected to the header pipe 6 on the refrigerant inlet side and the other end connected to the header pipe 6 on the refrigerant outlet side. Note that B in the figure means connection to an indoor unit (not shown), that is, refrigerant piping from the indoor unit (not shown) is connected to the header pipe 6 and the accumulator 5.

上記のように構成されているので、冷媒は、圧縮機４から吐出され冷媒入口側のヘッダ管６を経由して熱交換器３に流入し、熱交換器３内の配管を通った冷媒は、冷媒出口側のヘッダ管６から室内機へと流出する。そして、室内機から流入する冷媒は、アキュムレータ５を経由して圧縮機４に流入する。   Since it is configured as described above, the refrigerant is discharged from the compressor 4 and flows into the heat exchanger 3 via the header pipe 6 on the refrigerant inlet side, and the refrigerant that has passed through the piping in the heat exchanger 3 is Then, it flows out from the header pipe 6 on the refrigerant outlet side to the indoor unit. Then, the refrigerant flowing from the indoor unit flows into the compressor 4 via the accumulator 5.

空調室外機の筐体１内に設けられた制御部７は、圧縮機４の制御や、室外ファン２の制御を行う。また、筐体１内に図示しない温度センサを設け、この温度センサの検出する温度に基づいて、制御部７が圧縮機４や室外ファン２を制御するよう構成しても良い。   A control unit 7 provided in the casing 1 of the air-conditioning outdoor unit controls the compressor 4 and the outdoor fan 2. Further, a temperature sensor (not shown) may be provided in the housing 1 so that the control unit 7 controls the compressor 4 and the outdoor fan 2 based on the temperature detected by the temperature sensor.

なお、図１乃至図３では、冷媒配管を筐体１の中央付近に集約するように配設している。これにより、圧縮機４と熱交換器３との間の配管接続距離を最短とするよう構成することができる。   In FIG. 1 to FIG. 3, the refrigerant pipes are arranged so as to be concentrated near the center of the housing 1. Thereby, it can comprise so that the piping connection distance between the compressor 4 and the heat exchanger 3 may be made the shortest.

また、冷媒配管を筐体１の中央付近に集約することによって空きスペースができるので、例えば、メンテナンス頻度の高い部品をその空きスペースである筐体１の正面側（図２及び図３における下方側）に配置することができる。   In addition, since a free space is created by concentrating the refrigerant pipes near the center of the housing 1, for example, parts with high maintenance frequency are placed on the front side of the housing 1 that is the free space (the lower side in FIGS. 2 and 3). ) Can be arranged.

さらに、圧縮機４及びアキュムレータ５を筐体１の左右どちらか一方の側に設置し、制御部７をその反対側に設置している。このように、これら重量物のバランスを考慮して配置することにより、空調室外機の重心が、筐体１の中央付近にくるので、空調室外機を安定して設置することができる。   Furthermore, the compressor 4 and the accumulator 5 are installed on either the left or right side of the housing 1, and the control unit 7 is installed on the opposite side. In this way, by arranging these heavy objects in consideration of the balance, the center of gravity of the air conditioner outdoor unit comes near the center of the housing 1, so that the air conditioner outdoor unit can be stably installed.

次に動作について説明する。
例として、熱交換器３が凝縮器として動作する冷房動作について説明する。圧縮機４から吐出された高圧ガス冷媒は、冷媒配管や図示しない四方弁を通り、ヘッダ管６を経由して、熱交換器３の近接端部から熱交換器３に流入する。 Next, the operation will be described.
As an example, a cooling operation in which the heat exchanger 3 operates as a condenser will be described. The high-pressure gas refrigerant discharged from the compressor 4 flows into the heat exchanger 3 from the proximal end of the heat exchanger 3 through the header pipe 6 through a refrigerant pipe and a four-way valve (not shown).

一方、室外ファン２が回転することにより、筐体１の外部から熱交換器３を通過して筐体１の内部に入り、更に、空気吹出口１０から筐体１の外部上方へ吹出される空気の流れが発生する。そして、熱交換器３に流入した高圧ガス冷媒は、この空気と熱交換して凝縮し、高圧液冷媒となって図示しない室内機に流入していくことになる。   On the other hand, when the outdoor fan 2 rotates, it passes through the heat exchanger 3 from the outside of the housing 1 and enters the inside of the housing 1, and is further blown out from the air outlet 10 upward to the outside of the housing 1. Air flow is generated. The high-pressure gas refrigerant that has flowed into the heat exchanger 3 is condensed by exchanging heat with the air, and becomes high-pressure liquid refrigerant and flows into an indoor unit (not shown).

ここで、左右それぞれの熱交換器３を流れる冷媒は、熱交換器３の近接端部から反対側の端部へ、そして再び近接端部に戻ってくるという流れとなり、面Ｃに対して左右対称の流れとなる。また、それぞれの熱交換器３の上方に室外ファン２が設けられているので、熱交換器３を通過する空気の風速分布も、面Ｃに対して左右対称となる。   Here, the refrigerant flowing through the left and right heat exchangers 3 flows from the adjacent end of the heat exchanger 3 to the opposite end and back again to the adjacent end, It becomes a symmetric flow. Further, since the outdoor fan 2 is provided above each heat exchanger 3, the wind speed distribution of the air passing through the heat exchanger 3 is also symmetrical with respect to the plane C.

従って、左右それぞれの熱交換器３を通過する冷媒は、同じ風速分布を持つ空気と熱交換するので、左右の熱交換器において、冷媒配分が不要であり、かつ熱交換性能を同一とすることができる。   Accordingly, since the refrigerant passing through the left and right heat exchangers 3 exchanges heat with air having the same wind speed distribution, refrigerant distribution is not required in the left and right heat exchangers, and the heat exchange performance is the same. Can do.

なお、図示しない室内機に流れた高圧液冷媒は、室内機側熱交換器と熱交換して蒸発し、低圧ガス冷媒となって空調室外機に戻ってくる。そして、アキュムレータ５を経由した後、再び圧縮機４に流入して、以降循環することになる。   The high-pressure liquid refrigerant that has flowed into the indoor unit (not shown) exchanges heat with the indoor unit-side heat exchanger, evaporates, and returns to the outdoor unit as a low-pressure gas refrigerant. Then, after passing through the accumulator 5, it flows into the compressor 4 again and circulates thereafter.

なお、例えば冬季など外気温度が低いときには、暖房運転をすることになる。このとき、風速分布の小さい熱交換器３の近接端部付近では、熱交換器３の表面への着霜量が他の部分に比べて多くなってしまう。しかし、本実施の形態によれば、圧縮機４から吐出される高温ガス冷媒を熱交換器３の近接端部から熱交換器３に流入させることができるので、霜取運転を効率的に行うことも可能である。   When the outside air temperature is low, such as in winter, the heating operation is performed. At this time, the amount of frost formation on the surface of the heat exchanger 3 is increased in the vicinity of the adjacent end portion of the heat exchanger 3 having a small wind speed distribution as compared with other portions. However, according to the present embodiment, the high-temperature gas refrigerant discharged from the compressor 4 can flow into the heat exchanger 3 from the close end of the heat exchanger 3, so that the defrosting operation is performed efficiently. It is also possible.

実施の形態１によれば、左右それぞれの熱交換器３を通過する冷媒は、同じ風速分布を持つ空気と熱交換するので、左右の熱交換器３間で冷媒分配を不要とし、熱交換効率の高い空気調和機の室外機を得ることができるという効果がある。   According to the first embodiment, since the refrigerant passing through the left and right heat exchangers 3 exchanges heat with air having the same wind speed distribution, it is not necessary to distribute refrigerant between the left and right heat exchangers 3, and heat exchange efficiency It is possible to obtain an outdoor unit with a high air conditioner.

また、このとき、冷媒配管を筐体１の中央付近に集約するように配設すれば、圧縮機４と熱交換器３との間の配管接続距離を最短とするよう構成することができるので、コスト低減ができるという効果があるとともに、冷媒の圧力損失を抑制することができるので熱交換能力も高まるという効果がある。また、関連する配管部品も中央に集約することができ、筐体１内に空間的な余裕が生ずるので、メンテナンス作業性が向上するという効果がある。   At this time, if the refrigerant pipes are arranged so as to be concentrated in the vicinity of the center of the housing 1, the pipe connection distance between the compressor 4 and the heat exchanger 3 can be minimized. In addition to the effect that the cost can be reduced, the pressure loss of the refrigerant can be suppressed, so that the heat exchange capability is also increased. In addition, related piping parts can be gathered in the center, and a space is generated in the housing 1, so that there is an effect that maintenance workability is improved.

さらに、圧縮機４等の重量物のバランスを考慮して配置することにより、空調室外機の重心が、筐体１の中央付近にくるので、空調室外機を安定して設置することができるという効果がある。   Furthermore, by arranging the heavy load such as the compressor 4 in consideration of the balance, the center of gravity of the air-conditioning outdoor unit comes near the center of the housing 1, so that the air-conditioning outdoor unit can be stably installed. effective.

さらに、圧縮機４から吐出される高温ガス冷媒を熱交換器３の近接端部から熱交換器３に流入させることができるので、外気温度が低温である場合の霜取運転を効率的に行うことができるという効果がある。     Furthermore, since the high-temperature gas refrigerant discharged from the compressor 4 can flow into the heat exchanger 3 from the close end of the heat exchanger 3, the defrosting operation is efficiently performed when the outside air temperature is low. There is an effect that can be.

図５は、このヘッダ管６付近を拡大した要部拡大図である。一般に、熱交換器３は、複数の板状の熱交換器３が重ね合わされて形成されており、図５では、２枚の熱交換器３が重ね合わされて形成された例を示している。また、重ね合わされた熱交換器３を略コの字型に折り曲げる際には、一方の端部を揃えて折り曲げるが、本実施の形態では、面Ｃに対して対称すなわち、それぞれの熱交換器３の近接端部を揃えて折り曲げている。   FIG. 5 is an enlarged view of a main part in which the vicinity of the header pipe 6 is enlarged. In general, the heat exchanger 3 is formed by stacking a plurality of plate-shaped heat exchangers 3, and FIG. 5 shows an example in which two heat exchangers 3 are stacked. In addition, when the superimposed heat exchanger 3 is bent into a substantially U-shape, one end is aligned and bent, but in this embodiment, the heat exchanger 3 is symmetrical with respect to the plane C, that is, each heat exchanger. 3 adjacent end portions are aligned and bent.

そして、塞ぎ板８は、固定具９により熱交換器３に固定されており、双方の熱交換器３の間を塞ぐように配設されている。また、従来例では熱交換器３は左右非対称に形成されているので、塞ぎ板８の形状が複雑になっていたが、本実施の形態では熱交換器３が左右対称に形成されているので、塞ぎ板８の形状を簡素化することができる。   The closing plate 8 is fixed to the heat exchanger 3 by a fixture 9 and is disposed so as to close the space between the two heat exchangers 3. In the conventional example, since the heat exchanger 3 is formed asymmetrically in the left-right direction, the shape of the closing plate 8 is complicated. However, in the present embodiment, the heat exchanger 3 is formed symmetrically in the left-right direction. The shape of the closing plate 8 can be simplified.

室外ファン２が回転することにより、筐体１の外部から熱交換器３を通過して筐体１の内部に入り、更に、空気吹出口１０から筐体１の外部上方へ吹出される空気の流れが発生するが、熱交換器３を通過せずに熱交換器３の間を通過する空気の流れを塞ぎ板８が遮ることができる。   When the outdoor fan 2 rotates, it passes through the heat exchanger 3 from the outside of the housing 1 and enters the inside of the housing 1, and further, air that is blown upward from the air outlet 10 to the outside of the housing 1. Although a flow is generated, the plate 8 can block the flow of air passing between the heat exchangers 3 without passing through the heat exchanger 3.

実施の形態２によれば、簡素化された塞ぎ板８により、熱交換器３を通過せずに室外ファン２から吹出される風量を低減することができるので、熱交換効率を向上することができるという効果がある。   According to the second embodiment, the amount of air blown from the outdoor fan 2 without passing through the heat exchanger 3 can be reduced by the simplified closing plate 8, so that the heat exchange efficiency can be improved. There is an effect that can be done.

本発明は、空気調和機以外にも、給湯器等のヒートポンプを用いる装置に幅広く適用可能である。   The present invention can be widely applied to apparatuses using a heat pump such as a water heater other than an air conditioner.
