【０００１】
【発明が属する技術分野】
本発明は、空調室内に発散する不要な冷熱又は温熱を再利用し、空調装置使用電力を低減するデマンド制御技術に係り、特に空調室内気流分布特性と商用電源システムと空調装置構造それぞれの特殊性を手段化し、複数の関連手段を複合的にデマンド制御操作し、使用する商用電源電力量の削減を計る空調システム装置のデマンド制御技術に関するものである。
【０００２】
【従来の技術】
空気調和設備に係わるデマンド制御の公開技術には、一旦運転を開始した空調装置を途中で停止しても急激には空調効果を損なわない空気の熱慣性に着眼して、電力ピーク時に装置を自動停止させるピークカット方式、あるいは図９（Ｂ）に示すように、Ａ、Ｂ、Ｃなど複数の空調装置を順次、一時停止操作してサイクリック操作して運転を継続するもの、またここに図示しないが、能力別、使用目的別にグループ分けした空調装置の各々を、一時的に停止操作する運転ＯＦＦ時間とＯＮ時間の長さを変えて交互操作するレベル別方式がある（特開２００２−１０５３２号公報）。これらの共通目的は、図９（Ａ）に示すように、１サイクルｔ時間中に運転ＯＮ時間ａ、運転ＯＦＦ時間ｂを繰り返すことによりｂ／ｔの省エネ効果を得て、電力使用ピーク時の特に冷房期における商用電源電力のデマンド制御技術に活用することである。さらに前記交互操作技術を面積的に広く展開して複数の空調装置を群管理して行う遠隔技術の、デマンド制御技術も前記公報に開示する。
なお空調室の室内気候には、偏在する暖気は天井に、偏在する冷気は床面に停滞する傾向があり、天井配置の送風機が吹き出す空気によって拡散し、室内空気温度を平均化する周知技術があり、結果的に省エネ効果を得てきた。
【０００３】
【発明が解決しようとする課題】
空調システムにに対して前記ピークカット方式を含むデマンド制御技術は、空調装置を強制的に間欠運転して付帯する室温制御機能を機能不全させる不自然さがある。これに対し室温平均化機能を持たせる前記天井配置の送風機では、併設する空調装置と有機的に関連付けを行う技術を持っていない。
即ち、前記省電力技術と快適空間を形成する空調装置、あるいは空調装置と天井配置送風機の組み合わせに共通する欠点は、お互いの技術的役割を相互バラバラに展開し、例えば後設技術が前設備機能を押し除け、両者をリンクする技術を持たないことである。
特に電力量のピークカット技術としては、商用電源電力を間欠的に、あるいはシステム管理を加えながら単一電源によって電力の供給−停止操作するというもので、他の電源形態と組み合わせ、相互連係による複合操作を行いながら、商用電源電力を供給する公開技術はなかった。
そして熱媒体製造の室外機と一次空気供給の室内機との役割分担を組合せて成る空調装置に対しては、それらの特定機能を共に生かしたデマンド制御を行うものはなかった。
【０００４】
本発明は、暖房し又は冷房するために温度センサと熱交換器と送風機を付設する室内機と、熱媒体を加工、供給する放熱ファン付き圧縮機を付設する室外機を組み合わせて成る空調装置において、圧縮機運転を行う室外機の方が、送風機を運転する室内機側より遙かに電力負荷が大きい点に着目し、初期冷房負荷を供給した後に室外機の運転停止を出来るだけ長期間延長させ、その延長手段として、室内に偏在し停滞し勝ちで空地調和操作を妨げる冷気又は暖気を積極的に拡散させて室温平均化を行う送風機を付加配置し、その送風機を用いて結果的に運転停止する圧縮機の代替運転を行わせ、この代替運転によって電力消費の抑制を計る目的を持って開発したものである。その上で、ＡＣ電源を深夜電力充電によりＤＣ電源化して、その延長手段に選択的に電力を使用可能にする電源種類を多様化して、昼間時の商用電源電力のピーク時の節減効果を高め、かつ空調装置室温制御機能の正常使用を損なわずに、空調装置の制御操作を行えるようにしたデマンド制御装置を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
本発明に係る空調関連熱利用源の複合操作によるデマンド制御装置は、送風機と熱交換器と温度センサを有する室内機と、放熱ファンを付設する圧縮機から熱媒体を室内機に供給する室外機とから成る空調装置に加え、冷熱や温熱を発散するその他の設備負荷を併設する空調室においての、空調関連熱利用源の複合操作によるデマンド制御装置であって、室外機の操作時に、室内機のＯＮ操作に係わらず、少なくとも空調室内の暖気及び／又は冷気の停滞気団あるいは最低ないし最高の室内気温形成区域を解消する方向に気流を吹き出す調整送風機と、調整送風機の操作電力としてＡＣ電源を充電してＤＣ電源化し給電する蓄電池と、蓄電池に、室外機内設の圧縮機回転軸回転力又は放熱ファン風力の利用による発電機が出力する電力、あるいは商用電源からの深夜電力を選択的に充電可能に構成し、ＤＣ電源化した電源を用いて空調室の室温平均化気流操作を行い、商用電源電力に係る空調装置運転動力を極小化するように構成している。
【０００６】
そして本発明のデマンド制御装置は、調整送風機が、室外機運転ＯＦＦ期間中に運転ＯＮ動作を可能にすると共に、キュービクル型受電設備に配設する蓄電池付設の深夜電力充電器が供給するＤＣ電源あるいはＡＣ電源の、いずれかの電源電力切り換え操作を介して運転可能とする調整送風機であって、最低ないし最高の室内気温形成区域に選択的に特設、配置する温度センサと、室内機付温度センサ設定温度の検知動作によって生ずる室外機運転操作指示に基づき又は室外機運転のＯＮ−ＯＦＦ切替動作を検知して負荷信号を出力する負荷信号発生器と、室外機運転ＯＦＦ切替時に生ずる負荷信号によって調整送風機運転のＯＮ操作を行うと共に、負荷信号操作と併行して温度センサの設定温度を検知して調整送風機運転のＯＮ−ＯＦＦ操作を選択的に制御するコントローラとを構成し、室内機が吹き出す一次気流と調整送風機が吹き出す調整気流により、室温平均化空調操作と室外機運転のＯＦＦ状態延長操作を併行処理するように構成するものである。
【０００７】
また本発明のデマンド制御装置は、少なくとも空調室周辺の下部又は上部いずれかの一個所に調整送風機制御用の温度センサを配設した上で、室外機運転のＯＦＦ操作継続中において、室温が変化して温度センサが設定温度制御値を検知した一定時間後に、調整送風機運転のＯＦＦ操作を行うものである。
【０００８】
さらに本発明の、空調関連熱利用源の複合操作によるデマンド制御装置は、蓄電池付設の深夜電力充電器が、室外機付設の圧縮機回転軸に直接又は変速手段を介して間接的に接続する回転軸を回転して発電可能とする発電機と、室外機付設の放熱ファンが吹き出す風力を受けて発電する風力発電機とが出力する電力を充電可能にすると共に、蓄電池の余剰電力をＡＣ電源化した上で、室内機内設送風機やＡＣ電源電力を使用する照明その他の設備負荷に供給可能に構成している。
【０００９】
なおここに空調関連熱利用源とは、熱媒体を圧縮加工する圧縮機、該圧縮機を冷却する放熱ファン、異なる気流形態の保有熱を含有する室内分布空気及び異なる電源とを示し、複合操作とは、圧縮機にあっては媒体圧縮と発電動力発生の操作、放熱ファンでは冷却と風力発生の操作、室内分布空気に対しては一次空気温度と偏った温度差を有し、空調操作を妨げる冷気又は暖気の保有熱平均化操作、及び電源にあっては単独種電源ないし切替変換電源の操作、そして一次気流とは、室内機３が室内に供給する空気調和空気の気流を示す。
【００１０】
以上のように構成した本発明の、空調関連熱利用源の複合操作によるデマンド制御装置は、室外機運転ＯＦＦとほぼ同時に室内機が供給した一次気流と共に、付加新設する調整送風機の吹き出す調整気流を介して、冷房時には強制力によって室上層域に一旦、引き上げた冷気は周囲空気との混合を促す下方への循環を助けて室内空気の対流を促進しかつ室温平均化に寄与し、温度センサ付設の室内機周りを適度な低温度状態に保持する。この低温保持状態を延長することによって室内機の正常な室温制御機能を損なうことなく、室外機の運転ＯＦＦ状態を延長することによって、室外機側にも正常にその電力需要を停止する。
そして調整送風機は、暖房時又は冷房時のいずれにあっても比較的暖気から成る室上層部気流を強制流下し、一方、調整気流を介して室下層滞留域の比較的冷気の空気部分を結果的に上層へ汲み上げて、空調操作を妨げる停滞する暖気との混在作用を起こす対流を促し、室温が適正温度範囲内に近付いて平均化が進めば前記冷房時と同様の室外機の運転ＯＦＦ状態を延長するので、電力の消費抑制作用を生ずる。
深夜電力充電器の蓄電池を調整送風機の電源にする場合、電力ピーク時の商用電源電力負荷を、ＤＣ電源からＡＣ電源化して室内機運転に共用し、あるいは照明を含む他の軽度の設備負荷に、ＤＣ電源の余剰電力をＡＣ電源化することによって、電力ピーク時の対応能力が高まる。
さらに前記蓄電池に、室外機運転から付設発電機を介して取り出す電力を充電すれば、昼間帯にあっても負荷電力の一部を継続的に補充できる。
【００１１】
【発明の実施の形態】
以下、本発明に係る空調関連熱利用源の複合操作によるデマンド制御装置を、図によって説明する。図１は、本発明の、空調関連熱利用源の複合操作によるデマンド制御装置を説明するもので、（Ａ）はそのデマンド制御の全体構成を示すブロック図、（Ｂ）はその複合操作の機能内容を示すブロック図、図２は、本発明装置の、空調運転操作に係る構成を説明するもので、（Ａ）はそのデマンド制御の構成を示すブロック図、（Ｂ）はその制御操作のタイミングを示すタイムチャート、図３は、本発明の電源供給源に係るデマンド制御装置を説明するもので、（Ａ）はそのデマンド制御の第二の構成を示すブロック図、（Ｂ）はその充放電操作の一実施例によるタイミングを示すタイムチャート、そして図７は、同じく本発明デマンド制御装置の電源供給源の他の構成を説明するもので、（Ａ）はその全体構成を示すブロック図、（Ｂ）は他の構成を示すブロック図、（Ｃ）は別の構成を示すブロック図である。
本発明の、空調関連熱利用源の複合操作によるデマンド制御装置は、図１（Ａ）に示すように、商用のＡＣ電源８からの電力供給を受けて送風機３ａを内設する室内機３に、圧縮機２ａが加工した熱媒体を供給する室外機２を併設して室内に空調空気を供給する空調室に、調整送風機９を室上層域又は南面窓側などに生じる暖気の停滞気団を含む空調操作を妨げる室温空気を形成する区域（以下、暖気域という）や、あるいは室下層域又は北側床面などに生じる冷気域や冷却器２６を内設する冷蔵・冷凍ショーケース１９から該ケース外部に溢流してその周囲下層域に生じたものなどの、冷気の停滞気団を含む空調操作を妨げる室温空気を形成する区域（以下、冷気域という）などに選択的に設置して、同図（Ｂ）に示すように、一次気流の供給と調整空気供給操作や該冷気溢流のリユース操作によって、それが設置される冷気域ないし暖気域を解消するように、周囲空気を吸い込んで、吹き出す調整送風機９と、ＡＣ電源８をキュービクル型受電設備２０を介して、ＡＣ電源電力を充電器１４によってＤＣ電源化する蓄電池１５とを構成し、室外機２に付設する放熱ファン付き圧縮機から電力を生じる発電機３１ないし３２を設けて、該発電機出力電力や深夜電力を充電可能とする蓄電池１５により形成したＤＣ電源を用いて調整送風機９による室温平均化吹出気流操作を実施し、商用電源電力に係る空調装置運転動力を極小化するように構成した。ここに、図１に示す実線は、ＡＣ電源８からの電力線、二点鎖線はＤＣ電源からの電力線、一点鎖線囲み線は制御利用対象機器、二重囲み線は新規空調システム機器、矢印線は上手側手段の作用方向を示す連係線、２２はＡＣ／ＤＣ変換器ないし付設切替手段、２４はＤＣ／ＡＣ変換器ないし付設切替手段、２５はＡＣ／ＤＣ変換器付設スイッチング回路を示す。
【００１２】
また本発明のデマンド制御装置に用いる調整送風機９は、図２（Ａ）に示すように、室外機２と室内機３から成る空調装置１に併設してデマンド制御装置１０を配設する。該デマンド制御装置は、コントローラ４と該コントローラに接続して、室内に分散して付加配置する温度センサ６ないし１６及び主導的に運転ＯＮ／ＯＦＦ操作する調整送風機９と、該調整送風機の起動又は停止に連動して運転操作する調整送風機９ａ、９ｂ、‥とによって構成する。コントローラ４は、調整送風機９の運転ＯＮ／ＯＦＦ動作を行う例えば無接点ＳＳＲを用いたスイッチ７と空調装置１に接続してその動作と同期タイミングをとるパルス発信器１３とを付設するＩＣボード５と、該ＩＣボードに室外機２の運転ＯＮ／ＯＦＦ切替状態を検知して負荷信号を伝送する負荷信号発生器１２と操作異常時にアラームを発生する警報接点４ｂを内設したスイッチング回路４ａとから成る。
前記温度センサは、暖気域に配置するセンサ６及び／あるいは冷気域に配置するセンサ１６を選択的に分散配置する。そしてコントローラ４は、空調装置１側の室外機運転にリンクして調整送風機９を制御する空調装置側が定める運転条件と、設置場所の温度を監視する前記温度センサ側が調整送風機９の制御を決める運転条件とを併行して調整制御し、その上で行う該調整送風機が調整気流Ｒを吹き出して行う室温平均化空調操作によって、室外機２運転のＯＦＦ状態延長を複合的に操作する。即ち、室外機２の運転ＯＮ／ＯＦＦ切替時の接点変化又は室内機付温度センサ１１が室外機２に対して発生する制御信号を検知して動作する負荷信号発生器１２によって調整送風機９の運転ＯＮ／ＯＦＦを制御すると共に、空調装置１の操作状態とは関係なく、室温を室温平均化操作の点から監視する温度センサ６、１６がその設定温度Ｍを検知し、調整送風機９の運転ＯＮ／ＯＦＦを切り替え操作可能に構成する。ここに調整送風機９ａ、９ｂ、‥は、制御対象となる調整送風機９の動きによって従動するもので、以下、９ａ等は、調整送風機９によって代表表示して、各々の明示を省略する。
【００１３】
そして本発明によるデマンド制御装置は、図３（Ａ）に示すように、ＡＣ電源８の電力を調整送風機９に供給し、さらに設置するキュービクル型受電設備２０から、蓄電池１５を付設する深夜電力充電器１４を介して充電し、蓄えてＤＣ電源化した専用電力によって調整送風機９を運転操作可能にすると共に、該調整送風機への蓄電池１５容量不足の場合には、ＡＣ電源８をＡＣ／ＤＣ変換器２２を介して電力供給が選択的に可能になるように構成する。反対に該蓄電池容量に余剰電力があれば、ＤＣ電源電力をＤＣ／ＡＣ変換器２４を介してＡＣ電源化して前記調整送風機以外の、照明を含む設備負荷に供給可能に構成する。そして室内対流現象を継続して保持し易くするために、室外機２運転のＯＦＦ操作継続中に行う調整送風機９運転を、付設温度センサ６ないし１６の設定温度制御値Ｍを検知した一定時間後にＯＦＦ操作を行うように前記ＩＣボードを構成する。
なお図３（Ａ）に示す１０はデマンド制御装置、以下同じく実線は信号線、二重実線は電力線、点線枠は蓄電池の余剰電力の給電対象負荷、二重破線は該余剰電力給電線、及び点線は前記給電対象負荷に接続する信号線である。
【００１４】
さらに本発明のデマンド制御装置は、図７に示すように、蓄電池１５に供給する電源供給源４０が、同図（Ｂ）に示す空調装置１の室外機２を構成する圧縮機２ａ回転軸に対して、ここに図示しない直接又は変換手段を介して間接的に接続する付設回転軸を形成して、その軸回転によって発電する発電機３１、あるいは同図（Ｃ）に示すように、圧縮機２ａ付設の放熱ファン２ｂが吹き出す風力を受けて発電する風力発電機３２を配設し、それらが出力する電力を充電器１４を介して蓄電池１５に充電し、調整送風機９以下にその充電力を供給可能に構成する。
【００１５】
【実施例】
本発明の、空調関連熱利用源の複合操作によるデマンド制御装置の実施例を図によって説明する。図４は、本発明装置の一実施例を説明するもので、（Ａ）はその調整送風機の配置を示す部分平面図、（Ｂ）はその側断面を含む部分側面図、図５は、本発明装置の、基本構成の処理手順を示す流れ図、図６は、本発明に係る別構成の処理手順を示す流れ図、そして図８は、本発明装置の他の実施例を説明するもので、その実施状態を示す部分側面図である。
図４に示すように空調室３０では、空調装置の室内機３を、ここに記載しない室内機付温度センサを内設してその天井面に配置し、空気調和処理した一次気流Ｆを室下層の居住域に吹き出している。この吹き出し操作によって比較的重い冷気は室下層にコールドドラフトし、点で模式表示した冷気停滞域Ｃを生じ、夏季冷房時の南面又は西日射し込み窓際まで、一般的に前記冷気を継続して移動させる対流を起こせない。あるいは室内機３周囲の室上部では暖気停滞域Ｈが生じ易い。空調装置の運転操作は、室内機にほぼ密着して付設する機器周辺空気温度を検知して行われるので、その周囲空気温度が冷気又は暖気の停滞気団に包まれる場合には、温度センサ６、１６周囲の空気温度に一次気流の影響が及ばない。
ここに図示する室内機３周囲に複数台の調整送風機９等を配置する本発明装置の夏季を想定した実施例では、室内機３周囲天井面の暖気を下方に吹き付けて冷気停滞域Ｃに侵入させる、一次気流Ｆと調整気流Ｒの併合操作によって重い冷気を上方に随伴させ、接触する周囲空気により空気加熱し、その結果、冷気を含む混合空気Ｍの室内循環現象をもたらす。同図に示す４はコントローラであって、図２に示す室内機付温度センサ１１の動作信号を捉えて負荷信号発生器１２を作動し、ＩＣボード５を介してスイッチ（ＳＳＲ）７を入り切りし、調整送風機９を運転ＯＮ／ＯＦＦするものであり、６は調整送風機９と共に付設する温度センサで、点線表示はその配置位置が室内機３に近い場合には設置を省略することを示し、１７，１８はそれぞれ露出型ないし埋込型の調整送風機の吸込口付きファンケースを、そして二列並記の１０は、それぞれが独立系列のデマンド制御装置を同一電源で接続することを模式的に示したものである。
前記調整送風機配置の実施例において、図２（Ｂ）に示すように、コントローラ４が操作の始めからＯＮ状態にある場合に、室内機付温度センサ１１が設定制御温度範囲Ｈのときに室外機２の運転をＯＮ操作し、室温が点線表示のように変化して前記温度範囲がＬになって運転ＯＦＦ指示に変わると、室外機２が運転ＯＦＦ操作される。この温度変化を調整送風機９付設の温度センサ６が早めに独立して検知する場合、一次気流Ｆと混合気流Ｍが起こす対流によって冷気停滞域Ｃの冷気が動き出し、運転ＯＮする該調整送風機の調整気流Ｒの動きが相乗的に加わることによって冷気循環が促進し、室温平均化操作が早まり、室外機２が停止延長する省エネ操作を早期に開始できる。
室内温平均化がさらに進み、冷気の補給停止が長くなり過ぎれば、時間経過と共に室内温が上昇する。室内機付温度センサ１１の設定制御温度範囲が再びＨになれば、室外機２は運転を再開する。このような室外機と調整送風機の連係サイクル運転が繰り返されて、図２（Ｂ）に示す１サイクル時間ｔ１は、本発明装置配設以前より延長される。
【００１６】
本発明のデマンド制御装置の他の実施例は、図８に示すように、冷気を製造し、一次気流温度より低温の冷気溢流をほぼ常時、室内に拡散する冷凍冷蔵ショーケース１９が設置され、対流を阻害する陳列棚２１を配置する空調室３０に、前記図４に示した空調装置と調整送風機９を含む一連のデマンド制御装置１０を配設し、さらに加えて、図３（Ａ）に示す構成の室外機２、コントローラ４を併設するキュービクル型受電設備と深夜充電器１４を連係して外に設備する。図示するコントローラ４は、室外機４に付設する負荷信号発生器１２が該室外機の運転ＯＦＦ動作を検知して負荷信号を発生し、該信号を受けて調整送風機９を運転ＯＮ操作する、夏季における実施例を示す。調整送風機に連係して図８に示す６は、室内機付温度センサ１１から充分に離れ、かつ空調操作を妨げる暖気Ｈの暖気域に配置した温度センサである。
そして、図３（Ｂ）に示すように、例えば夜間２３時より翌朝７迄の時間帯に８時間以内の充電継続操作を常時行えるようにした深夜電力充電器１４が、コントローラ４に連係して２４時間運転ＯＮの充電／放電可能の待機状態にあり、充電モードＯＦＦ時にデマンド制御装置１０の運転モードＯＮ状態になり、その調整送風機タイミング時間ｔ２後にコントローラ４の制御モードがＯＮに、次いで放電モードに切り替った前記充電器からの電力を受けて調整送風機９の運転モードがＯＮ状態に操作される。その上で、この実施例のコントローラ４は、室外機２の圧縮機あるいは室内機付温度センサの運転ＯＮ／ＯＦＦにリンクして併行動作できるようになっている。
この実施例では、複数例の異種電源の実施態様を選択して、そのいずれかを実施できる。その一つは、調整送風機９以下を蓄電池１５のＤＣ電源を専用に駆動する。第二実施態様は、蓄電池容量が小の場合、電力ピーク時間帯前後にＤＣ電源から給電を受け、別時間帯にはＡＣ／ＤＣ変換器２２を介して、商用ＡＣ電源８からの電力をＤＣ電源化して、調整送風機９以下を動作させる。第三実施態様は、蓄電池容量に余剰電力がある場合、商用電源の電力ピーク時間帯前後にその余剰のＤＣ電源電力をＤＣ／ＡＣ変換器を介して、ＡＣ電源８により給電されている照明やその他の電力負荷２３に蓄電池電力を給電する。
【００１７】
さらに他の実施例では、冷気停滞域Ｃは、図８に示す冷気溢流が床上に滞留したもので、床置式調整送風機９を始動して、空調装置１の運転前に上方に冷気溢流を吹き出す運転モードを予めプログラムして、冷気温度Ｔ４の低温空気を上向き冷気流に乗せて汲み上げて室上層域を予冷すると共に、上向きから下向きに変わる冷気によって周囲の暖気を誘引して混合気流温度Ｔ５の吹出気流による循環を起こし、室外機２の起動を遅らせ、冷気製造の代替を行わせる。ここに、室内空気ないし気流の温度は、通常は暖気Ｈ温度＞Ｔ２（調整気流）＞Ｔ３（吸込温度）＞Ｔ５（上向き吹き上げ気流）＞Ｔ４（冷気停滞域気流）＞Ｔ１（吹出口一次気流）であり、冷気溢流がある場合にＴ１＞Ｔ４になる。
室上層部に配置する調整送風機９以下の吸込空気は、温度Ｔ３である場合に、気流温度Ｔ４、Ｔ５の影響を受けて天井面に停滞する暖気温度より低くなる。従って調整送風機９以下の吹出気流は、その温度Ｔ２と気流周囲温度との温度差が小になると、調整気流Ｒの到達距離を助長し、気流循環と室温平均化を促す。この現象は、室外機２、室内機３の空調運転ＯＮ操作の起動を遅らせ、また起動した後に、一旦停止した場合の正常停止期間を延長するデマンド制御を生じる。
【００１８】
昼間、電力を蓄電池１５に補充する技術を加えた本発明装置の実施例を図７によって説明する。同図（Ａ）に示すように、深夜電力充電器１４に代替しもしくは併設する電源供給源４０、即ち同図（Ｂ）と（Ｃ）に図示する発電機を作動して発生した電力を充電器１４によって蓄電池１５に補充電する。同図（Ｂ）に示すものは、圧縮機２ａ回転軸に、ここに記載しない直結接続や間接的にプーリや歯車などの変速機構を介して接続する回転軸を回転して発電する発電機３１であり、同図（Ｃ）に示すものは、圧縮機２ａの放熱を行う放熱ファン２ｂの放熱風力により回転力を得る風力発電機３２である。該蓄電池からのＤＣ電源とＡＣ電源８は、ＡＣ／ＤＣ（又はＤＣ／ＡＣ）変換器２２（又は２４）を付設するスイッチング回路２５によって、コントローラ４による制御を受けて、前記同様に調整送風機９以下の電力負荷に給電する。
【００１９】
このように構成した本発明の、空調関連熱利用源の複合操作によるデマンド制御装置は、図５及び／又は図６に示すように、次のようにして制御操作を行う。
そのデマンド制御の基本操作は、図５に示すように、空調装置１を運転ＯＮし（Ｓ１）、続いてデマンド制御装置１０をＯＮする（Ｓ２）。暫くして空調室３０は空気調和され、室内機付温度センサ１１が、室温制御に係る設定温度Ｍ（Ｈ≧Ｍ≧Ｌ）が、冷房時にはＭ以下、暖房時にはＭ以上に設定するＯＦＦ操作範囲になって、室温が一次気流温度に近付いたことを検知する（Ｓ３）と、室内機３が運転ＯＮ状態であっても室外機２が運転ＯＦＦする（Ｓ４）。この結果、コントローラ４が作動して、主導する調整送風機９を運転ＯＮ操作し、同系列の調整送風機９ａ、９ｂ、‥を従動させる（Ｓ５）。空調装置１の休止期間中に室内機付温度センサ１１が室温制御に係る設定温度Ｍの、冷房時にはＭ以上、暖房時にはＭ以下に設定するＯＮ範囲になると、室温が一次気流温度から離れ過ぎて室外機は運転ＯＮになり（Ｓ６）、この運転ＯＮ変化時に発生する負荷信号発生器１２の信号を検知するコントローラ４によって調整送風機は運転ＯＦＦに切り替わる（Ｓ７）。随時、室内機付温度センサ１１が前記ＯＦＦ範囲であるかの判別が行われ、ＯＦＦ範囲にあればステップ４に戻り、以下順次ステップ８までのステップが繰り返される。これに反しＯＦＦ範囲に入っていなければ、ステップ６に戻り、以下順次ステップが繰り返される（Ｓ８）か、デマンド制御装置１０と空調装置１の運転ＯＦＦ操作を共に行うとき、この制御操作は終了する。なお以下、前記ステップ３からステップ８までを繰り返すステップを停滞気団再利用ステップと称す。
【００２０】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a demand control technology for reducing unnecessary power consumption of an air conditioner by reusing unnecessary cold or warm heat radiated into an air conditioning room, and in particular, an air flow distribution characteristic of an air conditioning room and a special characteristic of a commercial power supply system and an air conditioner structure. The present invention relates to a demand control technique for an air conditioning system apparatus that performs a demand control operation of a plurality of related means in a complex manner and reduces the amount of electric power used in a commercial power supply.
[0002]
[Prior art]
Demand control technology related to air conditioning equipment includes a technology that automatically controls equipment during power peaks by focusing on the thermal inertia of air, which does not abruptly impair the air-conditioning effect even if the air-conditioning equipment that has started operation is stopped halfway. A peak cut method for stopping, or a method in which a plurality of air conditioners such as A, B, and C are sequentially stopped and operated cyclically to continue operation as shown in FIG. However, there is a level-based method in which each of the air conditioners grouped by capacity and purpose of use is alternately operated by changing the length of the operation OFF time and the ON time for temporarily stopping the operation (Japanese Patent Application Laid-Open No. 2002-10532). Publication). As shown in FIG. 9 (A), the common purpose of these is to obtain the energy saving effect of b / t by repeating the operation ON time a and the operation OFF time b during one cycle t time, and to obtain the energy saving effect at the peak of the power usage. In particular, it is to be used for demand control technology of commercial power in the cooling period. Further, a demand control technique of a remote technique for performing a group management of a plurality of air conditioners by expanding the alternate operation technique in a wide area is disclosed in the above-mentioned publication.
In the indoor climate of an air-conditioned room, unevenly distributed warm air tends to stagnate on the ceiling and unevenly distributed cool air tends to stagnate on the floor, and a well-known technique for averaging indoor air temperature is diffused by air blown by a ceiling-disposed blower. Yes, as a result energy saving effect has been obtained.
[0003]
[Problems to be solved by the invention]
The demand control technology including the peak cut method in an air conditioning system has an unnaturalness in which an air conditioner is forcibly operated intermittently and an accompanying room temperature control function malfunctions. On the other hand, the ceiling-disposed blower having the room temperature averaging function does not have a technology for organically associating the blower with an air conditioner attached thereto.
That is, the drawback common to the power saving technology and the air conditioner that forms a comfortable space, or the combination of the air conditioner and the ceiling-mounted blower is that the technical roles of each are developed in a mutually disparate manner. And have no technology to link the two.
In particular, as a technology for peaking power consumption, commercial power supply is intermittently operated or supplied and stopped by a single power supply while adding system management. There was no open technology to supply commercial power while operating.
For an air conditioner that combines the roles of an outdoor unit for producing a heat medium and an indoor unit for supplying primary air, there is no one that performs demand control utilizing both of these specific functions.
[0004]
The present invention relates to an air conditioner comprising a combination of an indoor unit provided with a temperature sensor, a heat exchanger and a blower for heating or cooling, and an outdoor unit provided with a compressor with a radiating fan for processing and supplying a heat medium. Focusing on the fact that the outdoor unit that operates the compressor has a much higher power load than the indoor unit that operates the blower, the operation of the outdoor unit is suspended for as long as possible after supplying the initial cooling load. As an extension means, a blower that unevenly disperses in the room, stagnates, and tends to hinder the operation of air-space harmful operation and disperses cold air or warm air actively to perform room temperature averaging is additionally arranged, and using the blower as a result of operation It was developed with the purpose of causing the compressor to perform an alternative operation to be stopped and to reduce power consumption by this alternative operation. In addition, the AC power source is converted to a DC power source by midnight power charging, and the types of power sources that can selectively use the power for the extension means are diversified to enhance the power saving effect at the peak of commercial power during the daytime. It is another object of the present invention to provide a demand control device capable of performing the control operation of the air conditioner without impairing the normal use of the air conditioner room temperature control function.
[0005]
[Means for Solving the Problems]
The demand control device according to the combined operation of the air-conditioning-related heat utilization sources according to the present invention includes an indoor unit having a blower, a heat exchanger, and a temperature sensor, and an outdoor unit that supplies a heat medium to the indoor unit from a compressor provided with a radiating fan. A demand control device that uses a combined operation of air-conditioning-related heat utilization sources in an air-conditioning room equipped with other equipment loads that dissipate cold or warm heat in addition to the air-conditioning system consisting of Regardless of the ON operation of the air conditioner, a regulated blower that blows airflow in a direction to eliminate at least a stagnant air mass of warm and / or cool air in the air-conditioned room or a minimum or maximum room temperature forming area, and charges an AC power supply as operating power of the regulated blower. And a storage battery that supplies DC power to supply power to the storage battery, and power output from the generator to the storage battery by using a compressor rotating shaft rotational force or a radiation fan wind power in the outdoor unit. Is designed to selectively charge late-night power from a commercial power supply, and to perform air-conditioning operation of the air-conditioning room at room temperature using a power supply that has been converted to a DC power supply to minimize the operating power of the air conditioner related to the commercial power supply. It is composed.
[0006]
The demand control device according to the present invention is configured such that the adjustment blower enables the operation ON operation during the outdoor unit operation OFF period, and a DC power supply or a DC power supply supplied by a midnight power charger provided with a storage battery disposed in the cubicle type power receiving facility. A regulated blower that can be operated via any one of power supply switching operations of an AC power supply, wherein a temperature sensor selectively and specially disposed in a lowest or highest indoor air temperature forming area and a temperature sensor with an indoor unit are set. A load signal generator that outputs a load signal based on an outdoor unit operation instruction issued by the temperature detection operation or detects an ON-OFF switching operation of the outdoor unit operation, and a blower adjusted by a load signal generated when the outdoor unit operation is switched OFF. In addition to performing the ON operation of the operation, the set temperature of the temperature sensor is detected in parallel with the load signal operation, and the ON / OFF operation of the adjusted blower operation is performed. And a controller for selectively controlling the air conditioner, and the primary airflow blown out by the indoor unit and the adjusted airflow blown out by the adjusting blower are configured to concurrently perform the room temperature averaging air conditioning operation and the OFF state extension operation of the outdoor unit operation. It is.
[0007]
In addition, the demand control device of the present invention includes a temperature sensor for controlling the regulated blower at least at one of the lower and upper portions around the air-conditioning room, and the room temperature changes during the OFF operation of the outdoor unit operation. Then, after a predetermined time after the temperature sensor detects the set temperature control value, the operation of turning off the adjusted blower operation is performed.
[0008]
Further, in the demand control device according to the present invention, which is a combined operation of an air-conditioning-related heat utilization source, a midnight power charger provided with a storage battery is connected to a compressor rotating shaft provided with an outdoor unit directly or indirectly through a speed change means. The power output from the generator that can generate power by rotating the shaft and the wind power generator that generates power by receiving the wind blown by the radiating fan attached to the outdoor unit can be charged, and the surplus power of the storage battery is converted to AC power. Then, it is configured to be able to supply to indoor equipment blowers, lighting using AC power, and other equipment loads.
[0009]
Here, the air-conditioning-related heat utilization source refers to a compressor that compresses a heat medium, a radiating fan that cools the compressor, indoor distribution air containing retained heat in a different airflow form, and a different power source. In the case of a compressor, the operation of medium compression and generation of power generation, the operation of cooling and wind power generation in a radiating fan, and the temperature difference between the primary air temperature and indoor distribution air are biased. The operation of averaging the retained heat of the cool air or the warm air and the operation of the single-type power supply or the switching conversion power supply, and the primary air flow refer to the air flow of the air-conditioned air supplied from the indoor unit 3 to the room.
[0010]
The demand control device by the combined operation of the air-conditioning-related heat utilization sources of the present invention configured as described above, together with the primary air flow supplied by the indoor unit almost simultaneously with the outdoor unit operation OFF, adjusts the adjusted air flow blown out from the additional newly-adjusted blower. During cooling, the cool air once pulled into the upper room area by the forced force during cooling assists the downward circulation that promotes the mixing with the surrounding air, thereby promoting the convection of the indoor air and contributing to the averaging of the room temperature. Around the indoor unit at a moderately low temperature. By extending the operation OFF state of the outdoor unit without impairing the normal room temperature control function of the indoor unit by extending the low temperature holding state, the power demand on the outdoor unit side is also normally stopped.
The regulating blower forcibly flows down the upper-layer airflow composed of relatively warm air at the time of heating or air-cooling, and on the other hand, produces the relatively cool air portion of the lower-layer stagnation area through the regulated airflow. If the room temperature approaches the appropriate temperature range and the averaging progresses, the outdoor unit will be in the same OFF state as in the cooling mode, by pumping up to the upper layer and promoting convection that causes a mixed effect with stagnant warm air that hinders the air conditioning operation , The effect of suppressing power consumption is produced.
When the storage battery of the midnight power charger is used as the power supply for the regulated blower, the commercial power supply load at the peak power time can be changed from the DC power supply to the AC power supply and used for indoor unit operation, or used for other light equipment loads including lighting. By converting the surplus power of the DC power supply into the AC power supply, the ability to cope with power peaks is increased.
Further, if the storage battery is charged with electric power extracted from the outdoor unit operation via the attached generator, a part of the load electric power can be continuously replenished even during the daytime.

【Example】
An embodiment of a demand control device according to a combined operation of an air conditioning-related heat utilization source according to the present invention will be described with reference to the drawings. 4A and 4B illustrate an embodiment of the apparatus of the present invention. FIG. 4A is a partial plan view showing the arrangement of the adjusting blower, FIG. 4B is a partial side view including a side cross section, and FIG. FIG. 6 is a flowchart showing a processing procedure of a basic configuration of the apparatus of the present invention, FIG. 6 is a flowchart showing a processing procedure of another configuration according to the present invention, and FIG. 8 is a view for explaining another embodiment of the apparatus of the present invention. It is a partial side view showing an implementation state.
As shown in FIG. 4, in the air conditioning room 30, the indoor unit 3 of the air conditioner is provided with an indoor unit-equipped temperature sensor (not shown) and arranged on the ceiling surface thereof, and the air-conditioned primary airflow F is placed in the lower layer of the room. Is blowing out to the residential area. By this blowing operation, relatively heavy cold air is cold-drafted to the lower part of the room, and a cold air stagnation area C schematically shown by a dot is generated, and the cold air is generally continuously moved to the south side or the west insolation window during summer cooling. No convection can occur. Alternatively, a warm air stagnation region H is likely to occur in the upper part of the room around the indoor unit 3. Since the operation of the air conditioner is performed by detecting the temperature of the air around the equipment attached almost in close contact with the indoor unit, when the ambient air temperature is wrapped in a stagnant air mass of cold air or warm air, the temperature sensor 6, The ambient air temperature is not affected by the primary airflow.
In the embodiment of the present invention in which a plurality of adjusting blowers 9 and the like are arranged around the indoor unit 3 shown in the figure, the warm air on the ceiling surface around the indoor unit 3 is blown downward to enter the cold air stagnant area C. The combined operation of the primary airflow F and the regulated airflow R causes heavy cold air to accompany the air upward, and the air is heated by the contacting ambient air. As a result, an indoor circulation phenomenon of the mixed air M containing the cold air is brought about. A controller 4 shown in FIG. 2 captures an operation signal of the temperature sensor 11 with the indoor unit shown in FIG. 2 and operates the load signal generator 12 to turn on / off the switch (SSR) 7 via the IC board 5. , For turning on / off the adjustment blower 9, reference numeral 6 denotes a temperature sensor attached together with the adjustment blower 9, and a dotted line indicates that the installation is omitted when the arrangement position is close to the indoor unit 3; , 18 respectively show a fan case with a suction port of an exposed type or a buried type adjustable blower, and 10 in two rows indicate that each demand control device of an independent system is connected with the same power supply.

When the temperature sensor 6 provided with the adjusting blower 9 detects the temperature change independently and early, the convection generated by the primary airflow F and the mixed airflow M causes the cool air in the cool air stagnation area C to start moving, and the operation of the adjusting blower to be turned ON. The synergistic addition of the movement of the air flow R promotes cool air circulation, accelerates the room temperature averaging operation, and can start the energy saving operation for stopping and extending the outdoor unit 2 at an early stage.
If the indoor temperature averaging proceeds further and the suspension of the supply of cold air becomes too long, the indoor temperature increases with the passage of time. When the set control temperature range of the indoor unit-equipped temperature sensor 11 becomes H again, the outdoor unit 2 resumes operation. By repeating such a linked cycle operation between the outdoor unit and the regulated blower, the one cycle time t1 shown in FIG. 2B is longer than before the apparatus of the present invention is provided.

The outdoor unit 2 having the configuration shown in FIG. 1 and a cubicle-type power receiving facility provided with the controller 4 and the late-night charger 14 are provided outside. The controller 4 shown in FIG. 1 is configured such that a load signal generator 12 attached to the outdoor unit 4 detects the operation OFF operation of the outdoor unit, generates a load signal, and receives the signal to operate the adjustment blower 9 to perform an ON operation. Examples of the present invention will be described. Reference numeral 6 shown in FIG. 8 in association with the adjusting blower is a temperature sensor sufficiently distant from the indoor unit-equipped temperature sensor 11 and arranged in a warm region of the warm air H that hinders the air conditioning operation.
Then, as shown in FIG. 3 (B), a late-night power charger 14 capable of constantly performing a charge continuation operation within 8 hours during a period from 23:00 at night to 7 in the next morning is linked to the controller 4. It is in a standby state in which charging / discharging is possible for 24 hours of operation ON, the operation mode of the demand control device 10 is turned on when the charging mode is turned off, the control mode of the controller 4 is turned on after the adjusted blower timing time t2, and then the discharging mode. The operation mode of the adjustment blower 9 is operated to the ON state by receiving the electric power from the charger switched to. In addition, the controller 4 of this embodiment can be operated in parallel with the operation ON / OFF of the compressor of the outdoor unit 2 or the temperature sensor with the indoor unit.
In this embodiment, a plurality of different power supply embodiments can be selected and implemented. One is to drive the DC power supply of the storage battery 15 exclusively for the regulated blower 9 and below. In the second embodiment, when the storage battery capacity is small, power is supplied from the DC power supply before and after the power peak time period, and the power from the commercial AC power supply 8 is supplied to the DC power supply via the AC / DC converter 22 in another time period. Turn on the power and operate the adjustment blower 9 and below. In the third embodiment, when there is surplus power in the storage battery capacity, the surplus DC power is supplied from the AC power supply 8 via the DC / AC converter to the lighting or the like before and after the peak power period of the commercial power.

In still another embodiment, the cool air stagnation region C is a region in which the cool air overflow shown in FIG. 8 stagnates on the floor, and starts the floor-mounted adjustable blower 9 to overflow the cool air before operating the air conditioner 1. Is programmed in advance, and low-temperature air at a cold air temperature T4 is pumped up by an upward cold air flow to pre-cool the upper layer area of the room, and cool air changing from upward to downward attracts the surrounding warm air to induce a mixed air flow temperature. Circulation by the airflow of T5 is caused to delay the start-up of the outdoor unit 2 and to substitute for cold air production. Here, the temperature of the indoor air or the airflow is usually the warm air H temperature> T2 (adjusted airflow)> T3 (suction temperature)> T5 (upward upward airflow)> T4 (cool air stagnant area airflow)> T1 (air outlet primary airflow) ), And T1> T4 when there is a cool air overflow.
When the temperature is T3, the intake air below the regulated blower 9 disposed in the upper layer of the room becomes lower than the warm air temperature stagnant on the ceiling surface under the influence of the airflow temperatures T4 and T5. Therefore, when the temperature difference between the temperature T2 and the ambient temperature of the airflow of the blowout airflow below the adjustment blower 9 becomes small, the reaching distance of the adjustment airflow R is promoted, and airflow circulation and room temperature averaging are promoted. This phenomenon causes demand control that delays the start of the air-conditioning operation ON operation of the outdoor unit 2 and the indoor unit 3 and extends the normal stop period when the operation is temporarily stopped after the start.

[0019]
The demand control device based on the combined operation of the air-conditioning-related heat utilization sources of the present invention configured as described above performs the control operation as follows as shown in FIG. 5 and / or FIG.
In the basic operation of the demand control, as shown in FIG. 5, the operation of the air conditioner 1 is turned on (S1), and then the demand control device 10 is turned on (S2). After a while, the air-conditioning room 30 is air-conditioned, and the temperature sensor 11 with the indoor unit detects that the set temperature M (H ≧ M ≧ L) related to the room temperature control is set to M or less during cooling and M or more during heating. Then, when it is detected that the room temperature approaches the primary airflow temperature (S3), even when the indoor unit 3 is in the operation ON state, the outdoor unit 2 is turned off (S4). As a result, the controller 4 operates to turn on the leading adjustment blower 9 and to operate the adjustment blowers 9a, 9b, ‥ of the same series (S5). When the indoor unit-equipped temperature sensor 11 is in the ON range of the set temperature M related to the room temperature control during the suspension period of the air conditioner 1, which is set to M or more during cooling and M or less during heating, the room temperature is too far from the primary airflow temperature. The outdoor unit is turned on (S6), and the controller 4 detects the signal of the load signal generator 12 generated when the operation is changed, and the adjustment blower is turned off (S7). At any time, it is determined whether or not the indoor unit-equipped temperature sensor 11 is in the OFF range. If the temperature is in the OFF range, the process returns to step 4 and the steps up to step 8 are repeated sequentially. On the other hand, if it is not within the OFF range, the process returns to step 6 and the following steps are repeated (S8), or when both the demand control device 10 and the air conditioner 1 are turned off, this control operation ends. . Hereinafter, the step of repeating steps 3 to 8 is referred to as a stagnant air mass reuse step.
[0020]
A procedure for performing a control operation of the demand control device 10 provided with the adjustment blower 9 by using a DC power supply obtained by charging midnight power will be described with reference to FIG.
In step 10 in which the battery 15 is being charged by the late-night power charger 14 not described here, when both the air conditioner 1 and the demand controller 10 described in steps 1 and 2 are in the operation ON state (S10), Next, the charging of the storage battery by the charger is turned off (S11), and the storage battery 15 is set to a discharge standby state (S12). When the floor-mounted adjustable blower 9c shown in FIG. 8 is in the operation OFF state (S13), which pumps up the overflow of the cool air, it is determined whether or not the attached temperature sensor 16 provided in the lower area is below the set temperature M (S14). ). If it is not less than M, the procedure returns to step 13. If it is not more than M, the adjusting blower 9c is turned on (S15), and then installed in the upper layer of the room shown in steps S3 to S8 shown in FIG. The stagnant air mass reuse step defined by the setting range of the additional temperature sensor 6 is activated (S16).
At the final stage of the operation procedure, when the operation of the air conditioner 1 is turned off (s17), the midnight power application time zone from, for example, 23:00 to the following morning at 7:00 (within 8 hours) is determined (S18). If it is not the time zone, the process returns to step 12 to continue the usable state of the storage battery power, and if it is the relevant time zone, the storage battery 15 is switched to the discharge OFF state and the charge ON operation is started (S19). Then, the operation of the demand control device 10 that drives the all-adjustment blower 9 is changed to the operation OFF (S20), and a series of operation procedures is completed.
[0021]
The above-described adjusted blower 9 shown in FIG. 4 was arranged on the ceiling, and the effect of reducing power consumption was obtained for two hours before and after the peak power during summer cooling. Here, for the air conditioner 1 having a load of 14 kW of the compressor 2b and a load of 320w of the blower 3a installed in the indoor unit, four regulated blowers with a single load of 30w that are operated exclusively for the AC power supply are used as a comparative example. The demand control by the intermittent method was carried out, and the device of the present invention was carried out. As a result, the device of the present invention consumed about 30% less power of the AC power supply than the power consumption of Comparative Example 100. Due to this power saving effect, when the power converted to DC power is applied to the apparatus of the present invention or when the reuse of the cold air overflow is performed, a significant effect can be obtained in the power saving of the commercial power supply and the real power consumption. Was confirmed.
