(発明の原理)
図1は、本発明の実施の形態1における運転時間補正部1の機能構成の一例を示す図である。図1に示すように、運転時間補正部1は、室内温度データ、目標温度データ、指定時刻データ、許容範囲幅データ、室内温度変動履歴データ、代表時間履歴データ、及び代表時間初期値データ等が入力され、運転開始時刻データ、具体的には、予冷予暖開始時刻データが出力される。ここで、予冷予暖開始時刻とは、予冷開始時刻及び予暖開始時刻の何れかを意味する用語と想定する。
t0’=t0×(Tk-Ta0)/(Ta1-Ta0) (1)
t0’=t0×((Tm-ΔTm)-Ta0)/(Ta1-Ta0) (2)
t’=|Ta0-Tm|×t0’ (3)
t0’=t0×(Ta0-Tk)/(Ta0-Ta1) (4)
t0’=t0×(Ta0-(Tm+ΔTm))/(Ta0-Ta1) (5)
t’=|Ta0-Tm|×t0’ (6)
図8は、本発明の実施の形態1における空調装置101の一例を示す図である。図8に示すように、空調装置101は、室外機111と、室内機113とを備える。室外機111は、例えば、家屋91の外側に設けられている。室内機113は、例えば、家屋91の内側に設けられている。空調装置101は、室内空間171を空調対象としている。つまり、空調装置101は、室内空間171が空気の制御対象空間である。
例えば、運転モードとして、冷房運転が選択された場合、冷凍サイクルの動作は以下のようになる。圧縮機121から吐出された冷媒は、四方弁122を通過して室外熱交換器123に流れる。室外熱交換器123に流れた冷媒は、室外空間172から吸い込まれた室外空気と熱交換して凝縮液化し、膨張弁124に流れる。膨張弁124に流れた冷媒は、膨張弁124で減圧され、室内熱交換器125に流れる。室内熱交換器125に流れた冷媒は、室内空間171から吸い込まれた室内空気と熱交換して蒸発ガス化し、四方弁122を通過して圧縮機121に再び吸入される。このようにして冷媒が流れることで、室内空間171から吸い込まれた室内空気が室内熱交換器125で冷却される。室内熱交換器125における冷媒と室内空気との熱交換量は、冷却能力Qと呼ばれる。冷却能力Qは、圧縮機121の回転数を変えることで調整される。
例えば、運転モードとして、暖房運転が選択された場合、冷凍サイクルの動作は以下のようになる。圧縮機121から吐出された冷媒は、四方弁122を通過して室内熱交換器125に流れる。室内熱交換器125に流れた冷媒は、室内空間171から吸い込まれた室内空気と熱交換して凝縮液化し、膨張弁124に流れる。膨張弁124に流れた冷媒は、膨張弁124で減圧され、室外熱交換器123に流れる。室外熱交換器123に流れた冷媒は、室外空間172から吸い込まれた室外空気と熱交換して蒸発ガス化し、四方弁122を通過して圧縮機121に再び吸入される。このようにして冷媒が流れることで、室内空間171から吸い込まれた室内空気が室内熱交換器125で加熱される。室内熱交換器125における冷媒と室内空気との熱交換量は、加熱能力Qと呼ばれる。加熱能力Qは、圧縮機121の回転数を変えることで調整される。
使用者によって、リモートコントローラー115に、上記で説明した指定時刻、例えば、在室開始時刻と、運転モード(冷房/暖房/除湿など)と、目標温度Tmとが入力されることで、空調装置101は、上記で説明したように、指定時刻に室内温度Taが目標温度Tmから許容範囲ΔTm以内に到達するように、例えば、予暖時間t’前から起動して暖房運転を行う。なお、後述するタイマー制御部213に対する各種設定の入力は、特に、リモートコントローラー115に限定されない。例えば、計測制御装置151又は計測制御装置153であってもよい。また、図19で後述するHEMSコントローラー323、通信装置328、又は端末329であってもよい。各種設定の入力では、運転モード(冷房/暖房/除湿など)と目標温度Tmの入力は省略してもよく、その場合は既存の運転モードと目標温度Tmとを用いることで入力を簡略化でき、使用者の利便性が向上する。既存の運転モードと目標温度Tmとは、リモートコントローラー115、計測制御装置151、計測制御装置153、HEMSコントローラー323、通信装置328、又は端末329の何れかに記憶された運転モード及び目標温度Tmである。

空調装置制御モジュール201は、積分制御を実行する。
空調装置制御モジュール201は、室内温度Taが急激に変化したか否かを判定する。空調装置制御モジュール201は、室内温度Taが急激に変化した場合、ステップS45に進む。一方、空調装置制御モジュール201は、室内温度Taが急激に変化しない場合、処理を終了する。
空調装置制御モジュール201は、微分制御を実行し、処理を終了する。
以上の説明から、空調装置制御モジュール201は、目標温度Tmに許容範囲ΔTmを設けることで、過剰な前倒し運転を回避させるので、余分な消費電力を削減させることができる。よって、空調装置制御モジュール201は、快適性を維持させつつ、余分な消費電力を削減させることができる。
実施の形態1との相違点は、室内機113に赤外線センサ143が設けられている点にある。
(赤外線センサ143の利用)
図14は、本発明の実施の形態2における空調装置101の一例を示す図である。図14に示すように、室内機113に赤外線センサ143が設けられ、室内空間171に人感センサ144が設けられている。赤外線センサ143は、放射温度等のような物体の放射エネルギーを検知する。よって、赤外線センサ143は、室内空間171に存在する躯体の温度を検知することができる。したがって、赤外線センサ143の検知結果を空調装置101の制御に用いる各種パラメータのうちの一つである室内温度Taに利用することができる。
実施の形態1及び実施の形態2との相違点は、目標温度Tmに制限をかける点にある。
(目標温度制限)
図15は、本発明の実施の形態3における空調装置制御モジュール201の機能構成の一例を示す図である。図15においては、図9で示した空調装置制御モジュール201と比べ、例えば、第1データ補正部247が追加されている点が相違する。具体的には、第1データ補正部247は、目標温度テーブル268、第3マッピングテーブル269、及び制限目標温度テーブル270を備え、第3マッピングテーブル269には、目標温度テーブル268と、制限目標温度テーブル270とを紐付ける写像関係が設定されている。例えば、タイマー制御部213は、目標温度制限指令が供給された場合、第1データ補正部247を用いて目標温度Tmに制限をかけ、制限目標温度データとして第3演算部243に供給する。
以上の説明から、空調装置制御モジュール201は、目標温度Tmの範囲を限定することで、冷房での冷やしすぎ又は暖房での暖めすぎを防ぐことで、暑さ又は寒さ等で健康を損ねる事態を回避することができつつ、省エネ性を向上させることができる。
実施の形態1~実施の形態3との相違点は、使用電流に制限がかかる点にある。
(電流制限)
図16は、本発明の実施の形態4における空調装置制御モジュール201の機能構成の一例を示す図である。 図16において、図9で示した空調装置制御モジュール201と比べ、例えば、第2データ補正部248が追加され、タイマー制御部213に電流制限指令が供給される点が相違する。第2データ補正部248は、使用電流範囲テーブル271、第4マッピングテーブル272、及び制限使用電流範囲テーブル273を備え、第4マッピングテーブル272には、使用電流範囲テーブル271と、制限使用電流範囲テーブル273とを紐付ける写像関係が設定されている。タイマー制御部213は、電流制限指令が供給された場合、第2データ補正部248を用いることで、使用電流に制限をかける。
以上の説明から、空調装置制御モジュール201は、電流制限値を設定するため、使用者の省エネ志向を制御に反映させることができるため、使用者の狙い通りに消費電力を抑制できることで省エネ性を向上させつつも、快適性を維持させることができる。
実施の形態1~実施の形態4との相違点は、自動運転の通達がなされる点にある。
(自動運転の通達)
図17は、本発明の実施の形態5における空調装置制御モジュール201の機能構成の一例を示す図である。図17においては、図9で示した空調装置制御モジュール201と比べ、タイマー制御部213の第4演算部244から外部に許可判定要求又は運転開始通知が供給される点が相違する。
以上の説明から、空調装置制御モジュール201は、冷凍サイクルの運転前に使用者に確認する動作を行うことで、使用者に空調装置101の空調情報を確認させることができるため、空調装置101の安全性を向上させることができる。また、使用者の帰宅時間が変わったと想定された場合であっても、空調装置制御モジュール201は、冷凍サイクルの運転前に使用者に確認する動作を行うため、不要な運転を回避することもできる。よって、空調装置制御モジュール201は、電力を無駄に消費することを回避することがっできるため、省エネ性を向上させることができる。
実施の形態1~実施の形態5との相違点は、使用者が帰宅しなかった場合の動作が定義されている点にある。
(使用者が帰宅しなかった場合)
図18は、本発明の実施の形態6における空調装置制御モジュール201の機能構成の一例を示す図である。図18に示すように、第5演算部245には、存否判定データとして、例えば、リモートコントローラー操作履歴データ、各種機器の使用状況データ、宅内消費電力データ、人感センサ検知データ、室内ドア開閉状況データ、通信状況データ、及び各種機器の位置情報データの少なくとも1つが供給される。
以上の説明から、空調装置制御モジュール201は、タイマー制御の運転を開始した後、予め設定された時間が経過しても使用者の在室、すなわち、使用者の帰宅が検知されなかった場合、空調装置101を停止したり、空調装置101の目標温度Tmを変更したりする。この結果、使用者が急な用事で帰宅時間が予定と比べて遅れた場合であっても、空調装置制御モジュール201は、使用者の不在時に無駄な運転を回避させることができるため、空調装置101の消費電力量を削減させることができる。
できるため、空調装置101の消費電力量を削減させることができる。
実施の形態1~実施の形態6との相違点は、HEMS2を利用して室内機113が制御される点にある。
図19は、本発明の実施の形態7におけるHEMS2の概略構成の一例を示す図である。HEMS2の情報を用いて空調装置制御モジュール201の制御を行うことで、快適性と省エネ性のバランスを自動調整し、使用者の利便性を向上させる。まず、HEMS2について説明する。
図19に示すように、HEMS2は、図8に示す家屋91に、空調装置101の室内機113、端末329、IHクッキングヒーター331、レンジグリル333、及び照明機器335等の家電機器である電気機器等の各種機器が設けられている。また、HEMS2は、図8に示す家屋91の屋外には、蓄電池341を搭載した電気自動車311、パワーコンディショナー313、太陽電池アレイ315、分電盤319、及び電力計測器321等の電気機器等の各種機器が設けられている。各電気機器は、電源線351で接続されている。また、電気機器のうち、家電機器は、電力会社317から供給される電力、太陽電池アレイ315から供給される電力、又は電気自動車311に搭載された蓄電池341から供給される電力で駆動し、電力計測器321で消費電力が測定される。
第1演算部241が、HEMS情報を用いて在室情報を求める例について記す。在室情報は、例えば、使用者が在室を始める時刻、使用者が在室を続ける時間幅、及び使用者が不在となる時刻を含む。在室情報が使用者に設定される場合、例えば、HEMSコントローラー323、通信装置328、又は端末329が利用される。
HEMS情報からの推定値に基づいて在室情報を得る動作は、在室情報が日々異なる場合に有効である。在室開始時刻が遅い日は起動時刻を遅らせて消費電力量を削減でき、在室開始時刻が早い日は起動時刻を早めて快適性を向上できる。
HEMS2の在室情報を用いれば、使用者が外から帰宅したのか、部屋から部屋へ移動したのか推定できる。これにより、タイマー制御の許容範囲ΔTmは、使用者が外から部屋に移動した場合と、部屋から部屋へ移動した場合によって変更する。例えば、使用者が外から帰宅した場合、外気温度に比べて室内温度Taが目標温度Tmに近づいていれば快適に感じるため、高い精度は求めらず、許容範囲ΔTmを大きくする。使用者が空調された部屋からタイマー制御の部屋へ移動する場合は、わずかな温度差でも不快に感じるため、高い精度が求められ、許容範囲ΔTmを小さくする。又は、タイマー制御対象の室内温度Taと、使用者がいる場所の温度を比較して、温度差が大きいほど許容範囲ΔTmを大きく設定してもよい。
使用者が移動に伴って感じる温度差を、タイマー制御の許容範囲ΔTmに反映することで、省エネ性と快適性のバランスを自動調整することができ、使用者の利便性が向上する。
遠隔から通信装置328を用いて、空調装置101のタイマー制御を実行する一例について説明する。使用者は、携帯電話、スマートフォン、タブレット、パソコン、又はカーナビ等の通信装置328を所有していると想定する。また、家屋91の内側である宅内又は家屋91の外側である宅外の何れかに存在する通信装置328が、公衆回線327を介して各種データをHEMSコントローラー323へ向けて送信したと想定する。
外出先から急遽タイマーの指定時刻を早めた場合、予冷予暖時間が予定よりも短くなり、指定時刻に室温が許容範囲ΔTmに収まらないことがある。この場合は第5演算部245の学習情報変更を回避することで、次以降のタイマー制御が適正に行われ、省エネと快適性を維持できる。又は、外出先から急遽タイマーの指定時刻を早めた場合は許容範囲ΔTmを広げることで適正に学習でき、次以降のタイマー制御が適正に行われ、省エネと快適性を維持できる。
実施の形態1~実施の形態7との相違点は、空調装置制御モジュール201の実装形態について説明する点にある。
図20は、本発明の実施の形態8における記録媒体401を介した各種装置等への各種モジュールの実装例を示す図である。図20に示すように、記録媒体401_1には、空調装置制御モジュール201が記憶され、空調装置101に記録媒体401_1がマウントされ、空調装置制御モジュール201が空調装置101にインストールされることで、上記で説明した各種動作を実行する各種機能が構成される。
以上の説明から、運転時間補正部1は、記録媒体401_1又は通信媒体、例えば、公衆回線327を介して、各種機器、例えば、空調装置101に構成される。よって、運転時間補正部1は、記録媒体401_1又は通信媒体を介して、通信可能な機器に構成されることができる。
