Abstract
Description
そのため、このような要望に対応した空気調和装置の室外機では、内部のスペースにおける熱交換器が占める割合が必然的に大きくなる。
このような室外機の熱交換能力を増大させる方法としては、例えば、熱交換器を従来のものと比較して大きくすることが考えられる。具体的には、例えば室外機の4側面全体に沿って熱交換器を配置することが考えられる。
この制御装置は、室外機内を流通する空気の流通路に配置されるため、通風の妨げとなる。そのため、特に風速の速い位置、例えば室外機の上部等のファンケーシングの近傍に配置することは好ましくない。
これにより、熱交換器を室外機の側面全体に沿って配置しつつ、制御装置の配置スペースを確保することができる。
さらに、特許文献2に記載の方法では、制御装置を多重構造として開閉式にするため、保守作業の際に制御装置が室外機の外側にせり出すことになる。そのため、保守作業の際には、制御装置を風雨、砂埃から保護するために養生する必要があり、保守作業を容易に行うことが困難であるという問題点があった。
以下、本発明の実施の形態1に係る空気調和装置について説明する。
図1は、本発明の実施の形態1に係る空気調和装置1の設置例を示す概略図である。
図1に示すように、空気調和装置1は、熱源機としての1台の室外機10と、複数台の室内機20とを備える。室外機10及び複数の室内機20は、2本の冷媒配管30で接続され、配管内を冷媒が流通する。
室外機10は、通常、ビル等の建物2の外の空間、例えば屋上等である室外空間3に設置され、冷熱又は温熱を生成して室内機20に供給する。
室内機20は、建物2の内部の空間、例えば居室やサーバールーム等である室内空間4に設置され、室外機10から供給された冷熱又は温熱により、冷房用空気又は暖房用空気を室内空間4に供給する。また、室内機20は、例えば床下に設置され、暖房運転時に供給される温熱により、床面を暖める床暖房として使用することもできる。
また、図1では、室外機10が室外空間3に設置されている場合の例を示すが、これはこの例に限定されない。例えば、室外機10は、換気口が設置された機械室等に設置してもよく、廃熱を建物2の外部に廃棄することができれば、建物2の内部に設置してもよい。
図2は、本発明の実施の形態1に係る空気調和装置1の回路構成の一例を示す概略図である。
図2の例では、1台の室外機10に対して1台の室内機20が冷媒配管30を介して接続される場合を示す。なお、上述したように、室外機10及び室内機20の台数は、この例に限られない。
室外機10は、圧縮機11、四方弁等の冷媒流路切替装置12、熱源側熱交換器13、アキュムレータ14、及び制御装置19を含んで構成される。
冷媒流路切替装置12及び熱源側熱交換器13は、ヘッダ15a及びヘッダ15bを介して連結される。ヘッダ15a及び15bは、熱源側熱交換器13の一方の端部に接続される。また、熱源側熱交換器13の他方の端部には、キャピラリーチューブ16が接続される。
室内機20は、例えば、空調対象空間の空気の冷房及び暖房を行うものである。室内機20は、室内熱交換器である利用側熱交換器21及び絞り装置22を含んで構成される。
利用側熱交換器21は、冷房運転の際に冷媒が冷熱を搬送している場合に蒸発器として機能し、空調対象空間の空気を冷却して冷房を行う。また、利用側熱交換器21は、暖房運転の際に冷媒が温熱を搬送している場合に凝縮器として機能し、空調対象空間の空気を加熱して暖房を行う。
次に、本実施の形態1に係る空気調和装置1における室外機10の構造について説明する。
図3は、本発明の実施の形態1に係る空気調和装置1における室外機10の構造の一例を示す概略図である。図3(a)は、室外機10の外観の一例を示す斜視図である。図3(b)は、室外機10の正面方向から見た概略断面図である。図3(c)は、室外機10の上面方向から見た概略断面図である。
図4は、本発明の実施の形態1に係る空気調和装置1における室外機10の内部構造の一例を示す概略図である。
なお、図3(a)においては、室外機10の内部構造を容易に理解できるようにするため、正面パネル50Bの下方部分の図示を省略している。また、図4においても同様に、外郭を形成する側面パネル50D及び上面パネル50Aや、アキュムレータ14及び制御装置19以外の内部に配置される圧縮機11、熱源側熱交換器13、冷媒配管30等の各種機器の図示を省略している。
筐体60は、上面パネル50A、正面パネル50B、背面パネル50C、2つの側面パネル50D及び底面パネル50Eとで構成される。
底面パネル50Eは、ドレンパンを兼ねており、ドレン水や室内に入り込んだ雨水等を室外へ排出する。なお、ドレンパンは、底面パネル50Eと別体に設けてもよい。
正面パネル50B、背面パネル50C及び2つの側面パネル50Dには、室外空気を取り込むための吸入口61が設けられる。
ここで、正面パネル50B、背面パネル50C及び2つの側面パネル50Dのそれぞれで形成される面のうち、少なくとも1つのパネルで形成される面が、保守作業等を行う際に使用される作業面とされる。この例では、正面パネル50Bで形成される面を作業面としている。
上面パネル50Aには、室外機10内の空気を室外へ放出するための排出口62が設けられる。排出口62は、排出機構としてのファン等の熱源側送風機64と、熱源側送風機64の周囲を覆うようにして設けられたファンガード63とで構成されている。
さらに、熱源側熱交換器13は、正面パネル50Bの上方側、例えば正面パネル50Bの上面側半分に沿うようにして設けられている。
ここで、室外機10内の高さ方向の位置と風速の関係について説明する。
図5は、本発明の実施の形態1に係る空気調和装置1における室外機10の風速分布について説明するための概略図である。
図5に示すように、室外機10内から放出される空気の風速は、上面側が最も速く、位置が下方になるにしたがって遅くなり、底面側が最も遅くなる。これは、上面パネル50Aにファン等の熱源側送風機64が設けられており、熱源側送風機64に近いほど風速が高くなるためである。
また、室外機10では、制御装置19を風速が最も遅い底面側に配置している。そのため、制御装置19が空気の流れに対して妨げとなるのを抑制でき、熱交換能力をさらに向上させることができる。
次に、制御装置19のより具体的な配置構造について説明する。
制御装置19を底面パネル50Eの正面側の下半分領域に載置した場合において、制御装置19の背面側に配置された圧縮機11や冷媒流路切替装置12等の機能部品をメンテナンスするときには、制御装置19を取り外す必要がある。
しかしながら、制御装置19のすべてを取り外すためには、制御装置19内の配線をすべて取り外す必要があり、取り外す作業に非常に時間がかかる。
なお、第2の制御装置19bは、筐体60からの取り外しが困難であるものの、必ずしも取り外すことができないものではない。しかしながら、第2の制御装置19bは、基本的に筐体60から取り外すことを想定していないため、以下の説明では「固定的に配置」と表現する。
例えば、第1の制御装置19aには、他の部品と比較して軽量である基板等の部品を搭載する。一方、第2の制御装置19bは、固定的に配置され、全体の重量を考慮する必要がないため、第2の制御装置19bには、ノイズ除去やインバータを駆動させるためのコイル等、他の部品と比較して重量のある電気部品を搭載する。
すなわち、第1の制御装置19aには、第2の制御装置19bに搭載された電気部品よりも軽量の電気部品を搭載する。
しかしながら、ヒートシンクは重量を有するため、取り外しが可能な第1の制御装置19aに配置することは好ましくない。
圧縮機11を第1の制御装置19aの背面に配置することにより、圧縮機11の交換等の際には、第1の制御装置19aを取り外すことで、作業面である正面パネル50B側から圧縮機11を容易に取り外すことができる。
また、室外機10内の風速がより遅くなる熱源側送風機64から遠い領域に制御装置19を配置するため、制御装置19が空気の流れに対して妨げとなるのを抑制でき、熱交換能力をさらに向上させることができる。
すなわち、本実施の形態1では、作業面側の熱源側熱交換器13を制御装置19よりも空気の風速が速い位置に配置することにより、熱交換能力を向上させることができる。
すなわち、これによって保守作業の際に取り外す第1の制御装置19aの重量を第2の制御装置19bの重量よりも軽くすることができ、保守作業等をより容易に行うことができる。
次に、本発明の実施の形態2に係る空気調和装置ついて説明する。
従来の空気調和装置では、室外機に配置された制御装置を取り外した場合、取り外した制御装置を室外機の外に置いておく必要があった。しかしながら、この場合には、制御装置が風雨、砂埃から保護するために養生する必要がある。
そのため、保守作業等の際には、取り外した制御装置を養生するという作業が発生し、保守作業が煩雑となっていた。
そこで、本実施の形態2に係る空気調和装置1では、保守作業等を行う際に風雨、砂埃等から制御装置19を保護するため、室外機10に配置された第1の制御装置19aを第2の制御装置19b上に載置し、仮置きできるようにしている。
図6(a)は、室外機10を正面から見た場合の内部構造を模式的に示す。同図において、点線で示す部分は、取り外す前の第1の制御装置19aが配置された位置を示す。
なお、図6に示す例は、第1の制御装置19aにおける正面側の面が第2の制御装置19bの側面側を向くように90°回転させて、第2の制御装置19b上に載置させた場合を示す。
図6(b)に示すように、第2の制御装置19bの上部には、仮置き用の固定金具51が設けられる。
そして、固定金具51の垂直に立設された面に沿うようにして、第1の制御装置19aを正面側から第2の制御装置19b上に載置することにより、第1の制御装置19aを確実に載置することができる。
こうすることにより、作業者は、第1の制御装置19aに搭載された基板を操作しながら保守作業等を行うことができる。
また、保守作業等を行う作業者は、取り外した第1の制御装置19aを養生することなく保守作業等を行うことができるため、保守作業が煩雑となるのを防ぐことができる。
なお、配線の「必要な長さ」とは、第1の制御装置19aに接続された配線を外すことなく、第1の制御装置19aを第2の制御装置19b上に載置することができる最低限の長さをいう。
さらに、それぞれの配線は、耐熱性や耐候性を確保する目的で配線ごとにチューブ等の保護部材で保護される場合があるため、それぞれの配線が太くなってしまう場合がある。
また、配線ごとに保護部材で保護する必要がないため、第1の制御装置19aに接続される配線の太さを抑制することができる。
また、これによって第1の制御装置19aを養生する必要がないため、作業者による保守作業が煩雑となるのを防ぐことができる。
次に、本発明の実施の形態3に係る空気調和装置ついて説明する。
本実施の形態3に係る空気調和装置1では、分割した第1の制御装置19aおよび第2の制御装置19bのうち、一方を他方の上に載置している。
図8(a)に示すように、第2の制御装置19bは、第1の制御装置19a上に載置される。第2の制御装置19bは、ボルト又はネジ等の締結具により取り外しが可能なようにして第1の制御装置19aに固定された状態で配置されている。なお、第1の制御装置19aについては、筐体60(図3参照)に対して取り外しが困難であるように固定されてもよいし、取り外しが可能なように固定されてもよい。
次に、本発明の実施の形態4に係る空気調和装置ついて説明する。
本実施の形態4に係る空気調和装置1では、1つの制御装置19内で、発熱量の多い電気部品と発熱量の少ない電気部品とを配置する位置を異ならせている。
図9に示すように、本実施の形態4では、1つの制御装置19内に、比較的発熱量が少なく、軽量である基板を含む電気部品(以下、「低発熱電気部品」と適宜称する)31aと、低発熱電気部品31aよりも発熱量が多く、重量がある基板を含む電気部品(以下、「発熱電気部品」と適宜称する)31bとが異なる位置に配置されて搭載されている。
次に、本発明の実施の形態5に係る空気調和装置ついて説明する。
例えば、制御装置19内に配置された低発熱電気部品31a及び発熱電気部品31bの両方を、冷媒配管30を流れる冷媒の放熱によって冷却する場合について考える。この場合に、冷媒温度を発熱量の多い発熱電気部品31bに対応する温度にすると、低発熱電気部品31aが過度に冷却され、低発熱電気部品31aの周囲に結露が発生することがある。そこで、本実施の形態5では、制御装置19の底面側に冷媒配管30を設け、低発熱電気部品31aに対する結露の影響を抑制するようにしている。
図10に示すように、本実施の形態5では、1つの制御装置19内に、低発熱電気部品31aと、発熱電気部品31bとが異なる位置に配置されて搭載されている。具体的には、低発熱電気部品31aが制御装置19内の上側に配置され、発熱電気部品31bが制御装置19内の下側に配置されている。また、制御装置19における低発熱電気部品31a及び発熱電気部品31bのそれぞれに対応する位置にヒートシンク52が設けられ、それぞれのヒートシンク52には、冷媒配管30が挿通されている。
このとき、冷媒配管30aに流れる冷媒の温度を下げることにより、冷媒配管30aの周囲に結露が発生する場合があるが、結露によって発生した水滴は、制御装置19の底面に溜まることになる。そのため、低発熱電気部品31a及び発熱電気部品31bに対する水滴による水濡れを防止することができる。
