- the floor area heated by the floor heating device is acquired using the infrared sensor 9, and the rotation speed of the compressor 1 is controlled to realize comfortable air conditioning. . That is, in the second embodiment, comfortable air conditioning can be realized without communicating with the floor heating device.
- Embodiment 2 the amount of reduction in the rotational speed of the compressor 1 is increased as the floor surface range heated by the floor heating device is wider. For this reason, while being able to suppress power consumption, a user's comfort can be improved.
- the ratio p3 is smaller than the ratio p1. That is, since the ratio p1 is larger than the ratio p3, the criterion for determining whether or not there is a floor heating device is strict, and erroneous determination of the presence or absence of the floor heating device can be avoided. Further, since the ratio p3 is smaller than the ratio p1, in the second embodiment, the rotation speed of the compressor 1 is appropriately controlled even when the range of the floor surface heated by the floor heating device is narrowed. It is possible to achieve more detailed air conditioning.
- the rotation speed of the compressor 1 is controlled based on the room temperature Ta and the floor surface temperature Tfav. Specifically, the control device Cnt reduces the rotational speed of the compressor 1 when the floor temperature Tfav approaches the room temperature Ta. For this reason, while being able to suppress power consumption, a user's comfort can be improved.

Abstract
Description
図1は、実施の形態1に係る室内機11を備えた空気調和装置10の概要構成図である。図2は、実施の形態1に係る室内機11の斜視図である。図1及び図2を参照して空気調和装置10の構成を説明する。なお、実施の形態1において、空調対象空間とは、例えば、室内機11が設置されている室内を指す。
空気調和装置10は、室内機11と、室外機12とを備えている。そして、室内機11と室外機12とは冷媒配管Pを介して接続されている。
室内機11には、室内熱交換器4及び送風ファン5が搭載され、室外機12には、圧縮機1、四方弁1B、室外熱交換器2及び絞り装置3が搭載されている。なお、絞り装置3は室外機12及び室内機11の外に配置されていてもよいし、室内機11内に配置されていてもよい。
また、空気調和装置10は、室内機11に設けられた赤外線センサー9と、室内機11に設けられたサーミスタ8と、室内機11から空調対象空間に供給される空気の方向を左右方向に調節する左右風向板7と、室内機11から空調対象空間に供給される空気の方向を上下方向に調節する上下風向板6とを備えている。
さらに、空気調和装置10は、制御装置Cnが搭載されている。なお、制御装置Cnは、室内機11に設けられた制御装置Cn1と、室外機12に設けられた制御装置Cn2とを含む。
四方弁1Bは冷媒の流路切替装置である。四方弁1Bは、圧縮機1の吐出側と室外熱交換器2とを接続し、且つ、圧縮機1の吸入側と室内熱交換器4とを接続する第1のポジションと、圧縮機1の吐出側と室内熱交換器4とを接続し、且つ、圧縮機1の吸入側と室外熱交換器2とを接続する第2のポジションとを切替ることができる。
サーミスタ8は、筐体11Aに設けられているものであり、空調対象空間の温度を検出する。サーミスタ8の検出結果(室内温度データ)は制御装置Cnに出力される。
上下風向板6は、筐体11Aの吹出口に配置され、左右風向板7に併設されている。上下風向板6は、左右風向板7は、例えば、板状部材で構成される。左右風向板7は、図示省略の軸に固定され、軸が動くことで左右に回動する。これにより、空気調和装置10は、筐体11Aの吹出口から吹き出される空気の方向を左右方向に調節することができる。
全体熱画像データとは、赤外線センサー9が空調対象空間を走査することで取得される。
全体画像データは、床面熱画像データと、壁面画像データとを含んでいる。なお、赤外線センサー9の走査範囲に壁面が入らず、走査範囲に入る対象が全て床面であれば、全体画像データには壁面画像データは含まれない。
全体熱画像データは、複数の要素データで構成される。なお、床面熱画像データは、複数の要素データで構成され、壁面画像データも、複数の要素データで構成される。
要素データは、LBS(Least significant bit)に対応するデータであり、赤外線センサー9で取得する熱データの最小単位である。要素データは、座標データ(x,y)と、この座標データに対応する温度データ(T)とを含む。この要素データは、第1の方向に対応する第1の座標x及び第2の方向に対応する第2の座標yを示す座標データと、第1の座標x及び第2の座標yに対応する位置の床面の温度を示す温度データTとで関連づけられる。すなわち、要素データは、(x,y,T)で表すことができる。
計時部21は、各種の時間を計時する機能を有する。例えば、計時部21は、空気調和装置10を起動してからの時間を計時する。
暖房運転時においては、圧縮機1から吐出された冷媒は、四方弁1Bを介して室内熱交換器4に供給される。つまり、室内熱交換器4は凝縮器として機能する。室内熱交換器4に供給された冷媒は送風ファン5によって供給される空気と熱交換し、凝縮液化する。室内熱交換器4から流出した冷媒は、絞り装置3で減圧されて低温低圧の気液二相冷媒となる。絞り装置3から流出した冷媒は、室外熱交換器2に供給される。つまり、室外熱交換器2は蒸発器として機能する。室外熱交換器2に供給された冷媒は蒸発ガス化する。室外熱交換器2から流出した冷媒は、四方弁1Bを介して圧縮機1の吐出側に戻される。
図3は、本形態に係る室内機11の赤外線センサー9の説明図である。
赤外線センサー9は、床面に対し下向き(例えば、俯角約24.5度)の角度で筐体11Aに取り付けられている。
赤外線センサー9の俯角が0度であれば、角度範囲9B4=90度-4(水平方向を0度としたとき、配光視野角9B1が0度未満となる受光素子の数)×7度(1個の受光素子の縦方向の配光視野角)=62度になる。実施の形態1の赤外線センサー9は、俯角が24.5度であるから、角度範囲9B4=62度-24.5度=37.5度となる。
図5Aは、空調対象空間(室内)の床面A及び壁W1、壁W2及び壁W3を含む全体熱画像データである。図5Bは、基準線L0、区画線L2及び区画線L1の説明図である。図5Cは、区画線L2と区画線L1との間における温度ムラに基づいて取得された境界線Lmの説明図である。床面Aは図5Aの点線の台形部分で示されている。また、床面Aは第1の方向Dr1(左右方向)及び第2の方向Dr2(奥行方向)に広がるように形成されている。床面A、第1の方向Dr1及び第2の方向Dr2は実空間上の概念である。第1の方向Dr1及び第2の方向Dr2は、水平方向に平行である。
また、全体熱画像データでは、空調対象空間にユーザーが在室していると、図5Dに示すように、ユーザーの存在する範囲の温度が上昇する。図5Dでは、第1の座標の一定範囲及び第2の座標の一定範囲のデータは、温度が上昇していることを示している。図5Dでは、この第1の座標の一定範囲及び第2の座標の一定範囲のデータを熱画像データD3として示している。
制御装置Cnは、図5Bに示すように、床面Aと、壁W1の面、壁W2の面及び壁W3の面とを区画するのに用いる基準線L0のデータを有している。基準線L0のデータは、例えば、空気調和装置の能力帯に関するデータ、及び、リモコン等から設定される室内機11の据付位置データに基づいて取得される。図5Bに示すように、基準線L0は、床面Aと、壁W1の面、壁W2の面及び壁W3の面との境界からはずれている。
制御装置Cnは、基準線L0から予め定められた画素数だけ離れた区画線L1と、基準線L0から予め定められた画素数だけ離れた区画線L2とを取得することができる。ここでは、一例として、予め定められた画素数は、2画素としている。なお、y座標は、区画線L1、基準線L0及び区画線L2の順番に小さい。つまり、基準線L0は、区画線L1と区画線L2との間に挟まれている。
制御装置Cnは、全体熱画像データD1のうち区画線L1と区画線L2との間におけるデータに基づいて、床面Aと、壁W1の面、壁W2の面及び壁W3の面とを区画する境界線Lmのデータを取得する。制御装置Cnは、y方向における温度ムラが大きい場合には、その画素の座標が境界線Lmの座標であると算出する。なお、y方向における温度ムラの算出にあたっては、全体熱画像データD1の絶対値を採用してもよいし、y方向における微分値を採用してもよい。
図6は、床暖房機器が運転しているときの全体熱画像データである。図6では、一例として床暖房機器が床面の全体を暖める運転モードで運転している様子を示している。図6を参照して第2の機能について説明する。
図7は、床暖房機器が床面Aの全体を暖める運転モードで運転しているときの全体熱画像データD1である。
図8は、空調対象空間(室内)の床面Aに家具が配置されている場合であって床暖房機器が運転しているときの全体熱画像データD1である。
しかし、床面Aの全体が暖まっていても、空調対象空間にソファ及びテーブル等の家具が配置されていると、床面Aから放射される赤外線の一部が家具によって遮られる。その結果、第1の座標の一定範囲及び第2の座標の一定範囲の熱画像データD4が、その周辺の範囲のデータと比較すると、温度が低下していることを示してしまう。なお、図8では、この第1の座標の一定範囲及び第2の座標の一定範囲のデータを熱画像データD4として示している。したがって、熱画像データD4の存在によって、高温度を示す熱画像データが分割されてしまうことになる。例えば、第1の方向(第1の座標x方向)の温度分布だけ、又は、第2の方向(第2の座標y方向)の温度分布だけに基づいて、床暖房機器の運転の判定をすると、熱画像データが分割される分、床暖房機器の運転の判定精度が低下してしまう。つまり、実際には床暖房機器が運転しているのに、高温度を示す範囲が分割されて短くなっているので、床暖房機器が運転していないと判定されかねないということである。実施の形態1に係る室内機11では、こういった誤判定を回避することができるようになっている。
具体的には、制御装置Cnは、予め定められた数の要素データのうち、第1の温度閾値よりも温度が高い要素データの割合が、予め定められた割合p2以上である場合に、床暖房機器が運転していると判定する。このように、制御装置Cnの判定部dは、第1の方向Dr1(第1の座標x方向)又は第2の方向Dr2(第2の座標y方向)の温度分布ではなく、第1の方向Dr1(第1の座標x方向)及び第2の方向Dr2(第2の座標y方向)の両方の温度分布を用いて、床暖房機器の運転の判定をする。したがって、床暖房機器の運転の判定精度を向上させることができるようになっている。この判定精度の向上効果は、特に、図8のように空調対象空間に家具が配置されている場合に大きい。
制御装置Cnは、全体の要素データのうち第1の温度閾値(例えば、25度)よりも温度が高い要素データの割合が、割合p2(例えば、60%)以上である場合に暖房機器が運転していると判定する。
図7において、全体の要素データの数は270個である。ここで、第1の温度閾値以上である要素データの数は、193個である。したがって、193/270=約71%であり、この数値は第1の値を超えている。したがって、制御装置Cnの判定部dは床暖房機器が運転していると判定する。
図8において、全体の要素データの数は270個であり、図7と同様である。ここで、第1の温度閾値以上である要素データの数は、家具が存在する分、163個と減少している。しかし、163/270=約60.3%であり、この数値は第1の値を超えている。したがって、制御装置Cnの判定部dは床暖房機器が運転していると判定することができる。つまり、制御装置Cnは、熱画像データD4の存在によって、高温度を示す熱画像データが分割されてしまっていても、床暖房機器が運転していると判定することができる。
床暖房機器は床面Aの全体を暖めるモードだけでなく、床面Aの半分の床面範囲、床面Aの3/4の範囲を暖めるモードを備えているものもある。こういった場合でも、制御装置Cnは、高精度に床暖房機器が運転しているか否かを判定することができる。
制御装置Cnは、第1の座標xが連続する第1の範囲であって第2の座標yが連続する第2の範囲に属する要素データのうち、第1の温度閾値(例えば、25度)よりも温度が高い要素データの割合が、割合p2(例えば、60%)以上である場合に、暖房機器が運転していると判定する。
室内機11の判定部dは、この構成を備えることによって、床面Aの半分の床面範囲等を暖めるモードにおいても、床暖房機器が運転していると判定することができる。なお、ここでは第1の値と第2の値とが等しいものとして説明しているが、異なっていてもよい。
図9において、第1の座標xが連続する第1の範囲r1であって第2の座標yが連続する第2の範囲r2に属する要素データの数は、135個である。ところで、制御装置Cnには、床面Aの半分が暖められるモードを想定し、第1の範囲r1及び第2の範囲r2が設定されている。なお、制御装置Cnは、その他の床暖房機器のモードを想定し、第1の範囲r1及び第2の範囲r2のバリエーションを複数備えている。
ここで、第1の温度閾値以上である要素データの数は、90個である。90/135=約66.6%であり、この数値は第2の値を超えている。したがって、制御装置Cnは床暖房機器が運転していると判定することができる。
また、第1の温度閾値及び第2の温度閾値の決定方法としては、大まかに25度及び35度として説明したが、それに限定されるものではなく、サーミスタ8の検出温度に基づいて決定してもよい。つまり、制御装置Cnは、サーミスタ8の検出温度よりも第1の温度閾値を大きい値とし、第1の温度閾値よりも第2の温度閾値を大きい値としてもよい。
図10は、実施の形態1に係る室内機11の制御フローチャート1である。
制御装置Cnは暖房運転を実行する。なお、ステップS0では、既に、床面範囲Bが取得され、床暖房機器が有ると判定された状態である。
制御装置Cnは床暖房機器が運転しているか否かを判定する。
(1)床暖房機器が運転していないと判定した場合には、ステップS4に移行する。
(2)床暖房機器が運転していると判定した場合には、ステップS2に移行する。ステップS2に移行する場合というのは、圧縮機1の回転数を維持する(ステップS4)又は増大させる(ステップS3)制御を行う。これは、床暖房機器が運転しているため、室内温度を赤外線センサー9の検出結果で補正してしまうと、ユーザーに冷風感を与えてしまう可能性があるためである。つまり、実際には室内温度がさほど高くない状況において、床暖房機器が運転していると、赤外線センサー9が床暖房で暖められた床面の温度に基づいて室内温度を補正してしまうことになる。つまり、体感温度が高く判断されてしまい、圧縮機1の回転数を低減させる制御が実行されてしまう可能性があるということである。実際には室内温度がさほど高くないのに、圧縮機1の回転数を低減させる制御を実行すると、ユーザーに冷風感を与える可能性がある。こういった状況を回避するために、圧縮機1の回転数を低減させる制御は行わず、圧縮機1の回転数を維持する又は増大させる制御を行う。
制御装置Cnは、リモコン等で設定される空調対象空間の設定温度から、サーミスタ8の検出温度を、減じた値が、α1以上であるか否かを判定する。
α1以上である場合にはステップS5に移行する。
α1以上でない場合にはステップS6に移行する。
制御装置Cnは圧縮機1の回転数を増大させる。
ここで、増大量は定数であってもよいし、設定温度と室温との差分に応じて変化させてもよい。つまり、この差分が大きいほど、圧縮機1の回転数の増大量を大きくしてもよい。
設定温度Tset
室温Ta≧α1・・・(式1)
ここで、α1=C1(定数)+補正値Co1である。
補正値Co1は、正の値とし、床面の温度に基づいて決定していない。
上記式1は次のように書き換えることができる。
設定温度Tset-(室温Ta+補正値Co1)≧C1(定数)
ここで、室温Ta+補正値Co1が体感温度に対応する数値である。
補正値Co1を設けているのは、床暖房機器が運転しているときにおいて、室内が暖まっているものと誤検出してしまうことを回避するためである。つまり、床暖房機器が運転しているときには、制御装置Cnが、赤外線センサー9が室内を走査すると床面の温度が高い分、室内が暖まっているものと誤検出してしまう可能性がある。そうすると、実際には、室内がさほど暖まっておらず、圧縮機1の回転数を下げてはならない状況であるのに、圧縮機1の回転数を下げてしまう制御に移行しかねない。
図11は、図10に示す制御フローチャート1の変形例である。
長時間暖房運転を実行していると、空調対象空間の足元の暖かい空気が上昇し、空調対象空間全体が暖まってくる。したがって、図10に示す制御フローチャート1は、一時的に実行するものであるとよい。図11に示す変形例に係る制御フローチャート1では、ステップS4を備えている。ステップS4においては、制御装置Cnが、ステップS3において圧縮機回転数を増大させてから予め定められた時間が経過したか否かを判定する。予め定められた時間を経過するまで、ステップS4のループを続ける。予め定められた時間が経過した場合には、ステップS5に移行して制御フローを終了する。なお、図11に示すステップS1、ステップS2、ステップS3、及びステップS5は、図10に示すステップS1、ステップS2、ステップS3及びステップS4と同様である。
なお、ステップS4からステップS5に移行する際には、制御装置Cnは、圧縮機1の回転数を低下させてもよい。例えば、制御装置Cnは、ステップS4からステップS5に移行する際には、圧縮機1の回転数をステップS3で増大させる前の回転数に戻す。
図12は、実施の形態1に係る室内機11の制御フローチャート2である。
制御装置Cnは暖房運転を実行する。なお、ステップS10では、既に、床面範囲Bが取得され、床暖房機器が有ると判定された状態である。
制御装置Cnは床暖房機器が運転しているか否かを判定する。
制御装置Cnは、サーミスタ8の検出温度から、赤外線センサー9の検出結果から取得する床面の温度Tfavを、減じた値(予め定められた温度差)が、β1以上であるか否かを判定する。
β1以上である場合にはステップS13に移行する。
β1以上でない場合にはステップS14に移行する。
制御装置Cnは圧縮機1の回転数を増大させる。
ここで、増大量は定数であってもよいし、サーミスタ8の検出温度と、赤外線センサー9の検出結果から取得する床面の温度Tfavとの差分に応じて変化させてもよい。つまり、この差分が大きいほど、圧縮機1の回転数の増大量を大きくしてもよい。
また、図12のステップS12の条件においても、空気調和装置10が起動してから規定時間が経過する前という条件があってもよい。つまり、ステップS12の条件、又は、空気調和装置10が起動してから規定時間が経過する前であるという条件を満たす場合には、ステップS13に移行し、両方の条件を満たさない場合にはステップS14に移行する。
空気調和装置10の起動時は、床暖房機器によって仮に床面が暖められていても、室内の温度が暖まっていない可能性が高い状況である。そこで、この構成を採用することで、ステップS2及びステップS12の条件を緩和して、圧縮機1の回転数を増大する制御へ促しやすくしている。これにより、ユーザーの快適性が低減することをより確実に回避することができる。
図13は、図12に示す制御フローチャート2の変形例1である。
図11に示すフローチャートと同様の趣旨により、図12に示す制御フローチャート2を、図13に示すフローチャートのようにすることができる。つまり、長時間暖房運転を実行していると、空調対象空間の足元の暖かい空気が上昇し、空調対象空間全体が暖まってくる。したがって、図12に示す制御フローチャート2は、一時的に実行するものであるとよい。図13に示す変形例に係る制御フローチャート2では、ステップS14を備えている。ステップS14においては、制御装置Cnが、ステップS13において圧縮機回転数を増大させてから予め定められた時間が経過したか否かを判定する。予め定められた時間を経過するまで、ステップS14のループを続ける。予め定められた時間が経過した場合には、ステップS15に移行して制御フローを終了する。なお、図13に示すステップS11、ステップS12、ステップS13、及びステップS15は、図12に示すステップS11、ステップS12、ステップS13及びステップS14と同様である。
なお、ステップS14からステップS15に移行する際には、制御装置Cnは、圧縮機1の回転数を低下させてもよい。例えば、制御装置Cnは、ステップS14からステップS15に移行する際には、圧縮機1の回転数をステップS13で増大させる前の回転数に戻す。
実施の形態1では、赤外線センサー9を用いて床暖房機器が運転しているか否かを判定し、圧縮機1の回転数を制御し、快適な空調を実現している。つまり、実施の形態1では、床暖房機器と通信しなくても、快適な空調を実現できる。
図10及び図11では制御対象が圧縮機1であったが、制御対象を送風ファン5とすることもできる。つまり、制御装置Cnは、暖房運転中において床暖房機器が運転していると判定した場合には、設定温度と、温度センサー(サーミスタ8)の検出温度に温度補正値(補正値Co1)を減じた体感温度とに基づいて、送風ファン5の回転数を制御する。また、制御装置Cnは、設定温度と体感温度との差が予め定められた値以上である場合には、送風ファン5の回転数を増大させる。なお、制御装置Cnは、送風ファン5の回転数を増大させた場合には、その後、低下させてもよい。例えば、制御装置Cnは、送風ファン5の回転数を増大させてから、予め定められた時間が経過した場合には、送風ファン5の回転数を増大させる前の回転数に戻す。
また、制御装置Cnは、設定温度と体感温度との差が予め定められた値未満である場合には、送風ファン5の回転数を維持する。これらの構成を備えていても、図10及び図11で説明した効果と同様の効果を得ることができる。
図12及び図13では制御対象が圧縮機1であったが、制御対象を送風ファン5とすることもできる。つまり、制御装置Cnは、暖房運転中において床暖房機器が運転していると判定した場合には、サーミスタ8の検出温度から、赤外線センサー9の検出結果から取得する床面の温度Tfavを、減じた値(予め定められた温度差)に基づいて送風ファン5の回転数を制御する。この減じた値がβ1以上であるときには、制御装置Cnは、送風ファン5の回転数を増大させる。なお、制御装置Cnは、送風ファン5の回転数を増大させた場合には、その後、低下させてもよい。例えば、制御装置Cnは、送風ファン5の回転数を増大させてから、予め定められた時間が経過した場合には、送風ファン5の回転数を増大させる前の回転数に戻す。
また、この減じた値がβ1未満であるときには、制御装置Cnは、送風ファン5の回転数を維持する。これらの構成を備えていても、図12及び図13で説明した効果と同様の効果を得ることができる。
図10~図13の制御対象は圧縮機1であったが、制御対象を上下風向板6とすることもできる。つまり、制御装置Cnは、床暖房機器が運転していると判定した場合には、上下風向板6に平行であり床面に交差する仮想面と床面とがなす角度が大きくなるように、上下風向板6の角度を制御する。つまり、上下風向板6を床面に向ける。これにより、室内機11は、空調対象空間の上部側よりも、下部側に供給する空気の量を増大させる。この構成を備えていていることで、制御装置Cnが、床暖房機器によって暖められた床面によって、ユーザーが寒さを感じていないものと誤判定してしまうことを回避することができる。
実施の形態2では、実施の形態1と共通する部分の説明は省略し、相違する部分を中心に説明する。実施の形態2と、実施の形態1とは、第3の機能が異なっている。実施の形態1においては、第3の機能は、床暖房機器が運転しているか否かの判定に対応していたが、実施の形態2においては、床暖房機器で加温されている床面の広さの判定に対応している。
制御装置Cnは、暖房運転を実行する(ステップS20)。
制御装置Cnは、全体熱画像データD1に基づいて床面熱画像データD2を取得する。つまり、制御装置Cnは、空調対象空間の床面範囲Bを算出する。
制御装置Cnは、床暖房機器が有りのフラグが立っているか否かを判定する。
フラグが立っている場合には、ステップS25に進む。
フラグが立っていない場合には、ステップS23に進む。
制御装置Cnは、床面熱画像データD2のうち予め定められた温度範囲に含まれるデータの座標の範囲が、床面範囲Bに対して割合p1(例えば、30%)以上であるか否かを判定する。なお、床面熱画像データD2のうち予め定められた温度範囲に含まれるデータとは、第1の温度範囲要素データに対応する。また、予め定められた温度範囲としては、一例として、25℃から35℃までとしている。
割合p1以上である場合には、ステップS24に進む。
割合p1以上でない場合には、ステップS21に戻る。
制御装置Cnは、床暖房機器が有りのフラグを立てる。
制御装置Cnは、床面熱画像データD2のうち予め定められた温度範囲に含まれるデータの座標の範囲が、床面範囲Bに対して割合p3(例えば、20%)以上であるか否かを判定する。なお、床面熱画像データD2のうち予め定められた温度範囲に含まれるデータとは、第1の温度範囲要素データに対応する。また、予め定められた温度範囲としては、一例として、25℃から35℃までとしている。
割合p3以上である場合には、ステップS27に進む。
割合p3以上でない場合には、ステップS26に進む。
ステップS26は、第1の温度範囲要素データを構成する要素データの座標の範囲が、床面範囲Bに対して、割合p3未満である。制御装置Cntは、圧縮機1の回転数を維持する。
ステップS27は、第1の温度範囲要素データを構成する要素データの座標の範囲が、床面範囲Bに対して、割合p3以上である。制御装置Cntは、圧縮機1の回転数を低減する。低減量は、第1の温度範囲要素データを構成する要素データの座標の範囲の広さに応じて設定することができる。
例えば、第1の温度範囲要素データを構成する要素データの座標の範囲が、床面範囲Bに対して、20%以上であって50%未満である場合には低減量をx1とし、50%以上であって80%未満である場合には低減量をx2とし、80%以上である場合には低減量をx3とする。なお、x3>x2>x1である。つまり、第1の温度範囲要素データを構成する要素データの座標の範囲が広いほど、圧縮機1の回転数の低減量を大きくするということである。
制御装置Cnは、サーミスタ8の検出温度(室温Ta)から、赤外線センサー9の検出結果から取得する床面の温度Tfavを減じた値(予め定められた温度差)が、V以下であるか否かを判定する。なお、床面の温度Tfavは、例えば、一定範囲の要素データが含む温度データを平均することで取得することができる。
V以下である場合には、ステップS29に移行する。
V以下でない場合には、ステップS30に移行する。
制御装置Cntは、図14に示す制御フローを終了する。
実施の形態2では、赤外線センサー9を用いて床暖房機器で加温された床面範囲の広さのデータを取得し、圧縮機1の回転数を制御し、快適な空調を実現している。つまり、実施の形態2では、床暖房機器と通信しなくても、快適な空調を実現できる。
