Description

【０００１】
【発明の属する技術分野】
本発明は、分離型空気調和機における室外ユニットの構成に関する。
【０００２】
【従来の技術】
一般に、室外ユニットと単数若しくは複数の室内ユニットとをつないだ分離型空気調和機は知られている。この種のものでは、設計必要馬力を大きくするときには、前記室外ユニットの台数を増やして、これらを複数台つないでいわゆるマルチ形の空気調和機を構成するのが一般的である。
【０００３】
しかしながら、設計必要馬力を大きくして、効率のよい空気調和システムを構築しようとするときに、前記室外ユニットの台数を増やすのではなく、一台の室外ユニットの馬力を増大させる方がよい場合がある。
【０００４】
【発明が解決しようとする課題】
しかしながら、従来、あまり大きな馬力を有する分離型空気調和機における室外ユニットは提案されていない。室外ユニットの大容量化を図ろうとすると、圧縮機の搭載台数が増えたり、熱交換器やアキュムレータ等の容量が大形化したりするが、従来では、これら冷媒回路を構成する各種機器類を、室外ユニットの本体内に効率よく収容し、しかも収容した機器類のメンテナンスを効果的に行なうための工夫等は提案されていない。
【０００５】
そこで、本発明の目的は、室外ユニットを大容量化した場合に、熱交換器や圧縮機やアキュムレータ等の冷媒回路を構成する各種機器類を、室外ユニットの本体内に効率よく収容し、しかも収容した機器類を効果的にメンテナンスすることのできる室外ユニットを提供することにある。
【０００６】
【課題を解決するための手段】
請求項１に記載の発明は、略コ字形に形成された二つの熱交換器の開口側を対向させて、これら熱交換器を室外ユニットの本体内に収容し、冷媒回路を構成する圧縮機等の残りの機器類を、前記二つの熱交換器で囲んだ空間内に収容し、前記室外ユニットの本体裏面側では二つの熱交換器を近接させて分流器によって接続し、前記室外ユニットの本体前面側では二つの熱交換器を離間させて当該熱交換器の間にサービスパネル、及び熱交換器に連なる冷媒管を接続する配管接続部を設けたことを特徴とするものである。
【０００７】
請求項２に記載の発明は、請求項１記載のものにおいて、前記室外ユニットの本体前面の両側には、熱交換用の空気の吸込口を形成したことを特徴とするものである。
【０００８】
請求項３に記載の発明は、請求項１又は２記載のものにおいて、前記サービスパネルをあけると、前記室外ユニットの本体前面には、前記圧縮機が露出することを特徴とするものである。
【０００９】
請求項４に記載の発明は、請求項１又は２記載のものにおいて、前記圧縮機は複数台設けられ、前記サービスパネルをあけると、前記複数台の圧縮機のうちの最も長時間に亘って運転制御される圧縮機が、前記室外ユニットの本体前面の最も手前に露出することを特徴とするものである。
【００１２】
【発明の実施の形態】
以下、本発明による空気調和機の室外ユニットの一実施の形態を、添付図面を参照して説明する。
【００１３】
図１において、１は２０馬力（以下、「ｐｓ」という。）の室外ユニット（以下、単に「親ユニット」という。）を示し、３は１０ｐｓの室外ユニット（以下、単に「子ユニット」という。）を示す。これらの親、子ユニット１，３は、図４に示すように、冷媒管５０を通じて室内ユニット５１につながれる。
【００１４】
「親ユニット」１について説明すると、この親ユニット１は、図４に示すように三台の圧縮機、すなわち１０ｐｓの定格圧縮機（スクロール）１５と、５ｐｓの定格圧縮機（ロータリー）１７と、パワーコントロール機構を備えた圧縮機（以下、「Ｐ／Ｃ圧縮機」という。）１９とを有している。この「Ｐ／Ｃ圧縮機」１９について若干説明すると、このＰ／Ｃ圧縮機１９は制御ポート１９ａを有しており、高圧弁１９ｂが開いて制御ポート１９ａに高圧がかかると（弁１９ｃは閉）、内部パワーコントロール機構（図示せず）が作動して、このＰ／Ｃ圧縮機１９は５ｐｓのフルパワーで運転される。一方、低圧弁１９ｃが開いて制御ポート１９ａに低圧がかかると（弁１９ｂは閉）、同じく内部パワーコントロール機構（図示せず）が作動して、このＰ／Ｃ圧縮機１９は２．５ｐｓのハーフパワーで運転される。
【００１５】
更に、「親ユニット」１は、三台の圧縮機１５，１７，１９のほかに、アキュームレータ２３、オイルセパレータ２５、四方弁２７、二つの熱交換器２９，３１、減圧装置３０，３２、レシーバタンク３３等を有する。なお、符号３４はオイルラインであり、バランス管３６につながる。２６は外部セーブ弁である。
【００１６】
「子ユニット」３は、図４に示すように、アキュムレータ５２、定格圧縮機５３、四方弁５４、熱交換器５５、減圧装置５６、並びに、レシーバタンク５７等を有する。定格圧縮機５３は１０ｐｓである。なお、このように構成された親ユニット１と子ユニット３には、上述したように、冷媒間５０を介して、室内ユニット５１がつながる。そして、この室内ユニット５１には、減圧装置５８、及び熱交換器５９が内蔵される。
【００１７】
この実施の形態によれば、親ユニット１における三台の圧縮機１５，１７，１９の合計馬力が２０ｐｓであるので、親ユニット１における二つの熱交換器２９，３１の容量もまた１０ｐｓづつの合計２０ｐｓである。
【００１８】
合計２０ｐｓは従来のものに比べて大形である。二つの熱交換器２９，３１は、図２に示すように、全体が略コ字形（従来のものとほぼ同じ）に成形されており、二つの熱交換器２９，３１は、親ユニット１の本体１０内に夫々の開口２９ａ、３１ａを対向させるように配置される。
【００１９】
二つの熱交換器２９，３１は左右対象であり、全く別々に成形され、親ユニット１の本体１０の両隅部１０ａ，１０ａにぴったりと収容される。そして、二つの熱交換器２９，３１で囲まれた空間１００内には、上述した冷媒回路を構成するための三台の圧縮機１５，１７，１９、アキュームレータ２３、オイルセパレータ２５、並びに四方弁２７等が収容される。この親ユニット１の本体１０の側面周囲には、本体前面の中央部を除いて、熱交換用の空気を取り込むための吸込口３５が全てに亘って形成される。なお、これらの吸込口３５から取り込まれる空気は、二つの熱交換器２９，３１で熱交換された後、天井面に設けられる排出ファン３７を通じて排出される。
【００２０】
親ユニット１の本体前面の中央には、図３に示すように、サービスパネル３９、及び冷媒管の配管接続部４１が臨んでいる。この配管接続部４１は、ガス管、液管の各サービスバルブ等で構成される。
【００２１】
配管接続部４１では、液管のサービスバルブ（細管）４１ａが、ガス管のサービスバルブ（太管）４１ｂよりも上位になるように縦一列に配置される。各サービスバルブ４１ａ，４１ｂが縦一列に配置されることにより、横一列に配置されるもの（従来）に比べて、親ユニット１の幅方向の寸法を小さくすることができる。ガス管のサービスバルブ（太管）４１ｂを下位に配置したのは、四方弁２７から引き出されるガス管をつなぎ易くするためである。この四方弁２７のガス管のつなぎ部は下向き（図示せず）であるので、親ユニット１におけるこの四方弁２７のつなぎ部から引き出したガス管を、上位に引き回すのは困難であり、従って下位に引き回すのであれば、接続は容易になるからである。
【００２２】
サービスパネル３９をあけると、図２に示すように、そこには圧縮機１５，１７，１９が露出する。上述した空気調和機では、Ｐ／Ｃ圧縮機１９が、運転制御上ほかの圧縮機１５，１７に比べて最も優先的に長時間に亘って運転される。したがって、ほかの圧縮機１５，１７に比べた場合には、通常、Ｐ／Ｃ圧縮機１９が頻繁にメンテナンスされるのが一般的である。
【００２３】
そこで、このメンテナンス性を考慮して、親ユニット１の本体前面の最も手前に、Ｐ／Ｃ圧縮機１９が露出するように、手前側からＰ／Ｃ圧縮機１９、圧縮機１７、圧縮機１５の順で配置される。
【００２４】
また、親ユニット１の本体１０内では、図２に示すように、熱交換器２９，３１につながる分流器４５は、本体裏面側に配置される。このように本体裏面側に分流器４５を配置することにより、分流器４５を本体前面側に配置する場合に比べ、本体前面側の開口スペースＳを広くすることができる。この実施の形態によれば、サービスパネル３９をあけた場合に、圧縮機等の露出度が高いので、メンテナンス性を向上させることができる。
【００２５】
また、空気調和機本体１０と壁面４７間には、サービス・メンテナンス用の通路４６が必要になる。この通路４６の存在により、本体手前側の吸込口３５近傍には十分な吸込スペースが確保される。
【００２６】
要するに、この実施の形態によれば、仮に、熱交換器２９，３１が大型化しても、夫々の熱交換器２９，３１を略コ字形に形成し、これらの熱交換器２９，３１の開口側を対向させて、二つの熱交換器を親ユニット１の本体１０内に収容すれば、冷媒回路を構成する圧縮機等の残りの機器類は、二つの熱交換器で囲んだ空間内に収容することができるので、親ユニット１をコンパクトに設計することができる。また、本体１０の中央部にサービスパネル３９を設けたので、このサービスパネル３９を開けることにより、冷媒回路を構成する機器類をメンテナンスすることができるので、メンテナンス性を向上させることができる。
【００２７】
【発明の効果】
この発明によれば、二つの熱交換器を略コ字形に形成して、これらの熱交換器の開口側を対向させて、二つの熱交換器を室外ユニットの本体内に収容しているので、冷媒回路を構成する圧縮機等の残りの機器類は、二つの熱交換器で囲んだ空間内に収容できるので、室外ユニットをコンパクトに設計することができる。また、本体手前中央部には、開閉可能なサービスパネルを設けたので、冷媒回路を構成する機器類を簡単にメンテナンスすることができる。

[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of an outdoor unit of an air conditioner according to the present invention will be described with reference to the accompanying drawings.
[0013]
In FIG. 1, 1 indicates an outdoor unit (hereinafter simply referred to as “parent unit”) having 20 horsepower (hereinafter referred to as “ps”), and 3 indicates an outdoor unit (hereinafter simply referred to as “child unit”) of 10 ps. ). These parent and child units 1 and 3 are connected to the indoor unit 51 through the refrigerant pipe 50 as shown in FIG.
[0014]
The “parent unit” 1 will be described. The parent unit 1 includes three compressors, that is, a rated compressor (scroll) 15 of 10 ps and a rated compressor (rotary) 17 of 5 ps, as shown in FIG. And a compressor (hereinafter referred to as “P / C compressor”) 19 having a power control mechanism. The “P / C compressor” 19 will be described briefly. The P / C compressor 19 has a control port 19a. When the high-pressure valve 19b is opened and a high pressure is applied to the control port 19a (the valve 19c is closed). ), An internal power control mechanism (not shown) is activated, and the P / C compressor 19 is operated at a full power of 5 ps. On the other hand, when the low pressure valve 19c is opened and a low pressure is applied to the control port 19a (the valve 19b is closed), an internal power control mechanism (not shown) is also activated, and the P / C compressor 19 is 2.5 ps. Operated with half power.
[0015]
Furthermore, in addition to the three compressors 15, 17, 19, the “parent unit” 1 includes an accumulator 23, an oil separator 25, a four-way valve 27, two heat exchangers 29, 31, decompression devices 30, 32, a receiver. A tank 33 and the like are included. Reference numeral 34 denotes an oil line, which is connected to the balance pipe 36. 26 is an external save valve.
[0016]
As shown in FIG. 4, the “child unit” 3 includes an accumulator 52, a rated compressor 53, a four-way valve 54, a heat exchanger 55, a pressure reducing device 56, a receiver tank 57, and the like. The rated compressor 53 is 10 ps. The indoor unit 51 is connected to the parent unit 1 and the child unit 3 configured as described above through the refrigerant 50 as described above. The indoor unit 51 includes a decompression device 58 and a heat exchanger 59.
[0017]
According to this embodiment, since the total horsepower of the three compressors 15, 17, 19 in the parent unit 1 is 20 ps, the capacities of the two heat exchangers 29, 31 in the parent unit 1 are also 10 ps each. The total is 20 ps.
[0018]
The total 20 ps is larger than the conventional one. As shown in FIG. 2, the two heat exchangers 29 and 31 are formed in a substantially U shape (substantially the same as the conventional one), and the two heat exchangers 29 and 31 are the same as those of the parent unit 1. It arrange | positions so that each opening 29a, 31a may be opposed in the main body 10. FIG.
[0019]
The two heat exchangers 29 and 31 are the left and right objects, are completely formed separately, and are closely accommodated in both corners 10a and 10a of the main body 10 of the parent unit 1. In the space 100 surrounded by the two heat exchangers 29 and 31, there are three compressors 15, 17, and 19, an accumulator 23, an oil separator 25, and a four-way valve for constituting the refrigerant circuit described above. 27 etc. are accommodated. Around the side surface of the main body 10 of the parent unit 1, a suction port 35 for taking in air for heat exchange is formed all over the center of the front surface of the main body 1. In addition, the air taken in from these suction ports 35 is discharged through a discharge fan 37 provided on the ceiling surface after heat exchange is performed by the two heat exchangers 29 and 31.
[0020]
As shown in FIG. 3, a service panel 39 and a refrigerant pipe connection part 41 face the center of the front surface of the main unit 1. This pipe connection part 41 is comprised by each service valve etc. of a gas pipe and a liquid pipe.
[0021]
In the pipe connection part 41, the service valve (thin tube) 41a of the liquid pipe is arranged in a vertical row so as to be higher than the service valve (thick pipe) 41b of the gas pipe. By arranging the service valves 41a and 41b in a single vertical row, the dimension in the width direction of the parent unit 1 can be made smaller than those arranged in a horizontal row (conventional). The reason why the gas pipe service valve (thick pipe) 41b is arranged at the lower position is to make it easy to connect the gas pipe drawn from the four-way valve 27. Since the connecting part of the gas pipe of the four-way valve 27 faces downward (not shown), it is difficult to draw the gas pipe drawn out from the connecting part of the four-way valve 27 in the parent unit 1 to the upper side, and therefore the lower part. This is because the connection is facilitated if it is routed around.
[0022]
When the service panel 39 is opened, as shown in FIG. 2, the compressors 15, 17 and 19 are exposed there. In the air conditioner described above, the P / C compressor 19 is most preferentially operated over a long period of time compared to the other compressors 15 and 17 in terms of operation control. Therefore, when compared with the other compressors 15 and 17, the P / C compressor 19 is generally maintained frequently.
[0023]
Therefore, considering this maintainability, the P / C compressor 19, the compressor 17, and the compressor 15 are arranged from the front side so that the P / C compressor 19 is exposed in front of the front surface of the main unit 1. Arranged in order.
[0024]
Moreover, in the main body 10 of the parent unit 1, as shown in FIG. 2, the flow divider 45 connected to the heat exchangers 29 and 31 is disposed on the back side of the main body. By disposing the current divider 45 on the back surface side of the main body in this way, the opening space S on the front surface side of the main body can be widened as compared with the case where the current divider 45 is disposed on the front surface side of the main body. According to this embodiment, when the service panel 39 is opened, since the degree of exposure of the compressor or the like is high, the maintainability can be improved.
[0025]
Further, a service / maintenance passage 46 is required between the air conditioner body 10 and the wall surface 47. The presence of the passage 46 ensures a sufficient suction space in the vicinity of the suction port 35 on the front side of the main body.
[0026]
In short, according to this embodiment, even if the heat exchangers 29 and 31 are enlarged, the respective heat exchangers 29 and 31 are formed in a substantially U shape, and the openings of these heat exchangers 29 and 31 are formed. If the two heat exchangers are accommodated in the main body 10 of the parent unit 1 with the sides facing each other, the remaining devices such as the compressor constituting the refrigerant circuit are placed in a space surrounded by the two heat exchangers. Since it can be accommodated, the parent unit 1 can be designed compactly. In addition, since the service panel 39 is provided in the central portion of the main body 10, by opening the service panel 39, it is possible to maintain the devices constituting the refrigerant circuit, so that maintainability can be improved.
[0027]
【The invention's effect】
According to this invention, two heat exchangers are formed in a substantially U shape, and the two heat exchangers are accommodated in the main body of the outdoor unit with the opening sides of these heat exchangers facing each other. Since the remaining devices such as the compressor constituting the refrigerant circuit can be accommodated in the space surrounded by the two heat exchangers, the outdoor unit can be designed compactly. In addition, since a service panel that can be opened and closed is provided at the front central portion of the main body, the devices constituting the refrigerant circuit can be easily maintained.
