Description

床暖房マット１４２は、熱動弁７６のオン／オフに応じて温水チューブ１４６内を循環される温水によってマット１４４が加熱される。
【００５０】
なお、本実施の形態では、１サイクルを２０min （２０分）としてデューテー比を設定しており、通常、ステップ１以上で運転される。また、ステップ１６は、床暖房ユニット１４２が運転を停止した状態となる。また、図１及び図５に示されるように、熱源ユニット２６には、床暖房マット１４２のマット１４４内に設けられている図示しないサーミスタ等の温度検出手段からの信号線１４８が接続されており、信号線１４８を介してマット１４４の温度が所定値（例えば３１°Ｃ）を越えたことを検出すると温水の循環を停止させる。
【００５１】
図６に示されるように、連動コントローラ２０は、マイコン１５０を備えたコントロール基板１５２に、データ通信用の通信Ｉ／Ｆ基板１５４及びシリアル通信用の通信Ｉ／Ｆ基板１５６が接続されている。また、連動コントローラ２０内には、温度検出基板１５８及び受信基板１６０が設けられており、これらがコントロール基板１５２に接続されている。
【００５２】
図２に示されるように、連動コントローラ２０には、受信窓１６２が形成されており、この受信窓１６２へ向けてシステムリモコン１３０を操作することにより、システムリモコン１３０から送出される操作信号が受信基板１６０で受信される。
【００５３】
図７に示されるように、システムリモコン１３０は、ＬＣＤ等の表示手段を用いた表示部８７と、温水エアコン１０と床暖房マット１４２の運転条件の設定を行うための種々の操作ボタンが配置された操作パネル８８が設けられている。すなわち、システムリモコン１３０は、温水エアコン１０の運転を操作と床暖房マット１４２の運転操作機能を兼ね備えたマルチタイプリモコンとなっており、表示部８７には、操作パネル８８上で設定された温水エアコン１０と床暖房マット１４２の運転条件等が表示される。なお、操作パネル８８はカバー８９を開くことにより開放される。
【００５４】
操作パネル８８には、運転／停止ボタン９１、温度設定ボタン９２、室温設定手段としての温水エアコン１０用の温度下げボタン９３Ａと温度上げボタン９３Ｂ、床暖温度設定手段としての床暖房マット１４用の温度下げボタン９４Ａと温度上げボタン９４Ｂと共に、冷暖切替ボタン９５、選択手段としての床暖房ボタン９６が設けられている。冷暖切替ボタン９５を操作することにより、運転モードが「冷房」、「自動」、「暖房」、「暖房、床暖房」、「床暖房」、「ドライ」、「送風」と切り替わり、さらに冷暖切替ボタン９５を操作することにより「冷房」モードに切り替わる。また、システムリモコン１３０には、通常のエアコンのリモコンスイッチと同様に、風向（上下フラップ５４の向き）、風量（クロスフローファン９０の回転数）及びタイマ運転等の設定が可能となっている。
【００５５】
温水エアコン１０は、「冷房」、「自動」、「暖房」「暖房、床暖房」、及び「ドライ」モードで運転される。また、床暖房マット１４２は、「暖房、床暖房」及び「床暖房」モードで運転され、「暖房・床暖房」モードに設定されているときに、床暖房ボタン９６を操作することにより、温水エアコン１０と床暖房マット１４２の運転が「自動コンフォト」モード、「自動エコノミ」モード及び「手動」モードに切り替えられ、「床暖房」モードに設定されているときに床暖房ボタン９６を操作することにより床暖房マット１４２の運転が「自動」モード及び「手動」モードに切り替えられる。「手動」は、設定温度（設定室温及び設定床温）をマニュアル操作によって設定する運転モードとなっている。
【００５６】
温度下げボタン９３Ａと温度上げボタン９３Ｂの操作によって温水エアコン１０によって空調暖房する室内温度（設定室温）が設定されると、この設定室温がシステムリモコン１３０の表示部８７に数値として表示される。また、温度下げボタン９４Ａと温度上げボタン９４Ｂの操作によって床暖房マット１４２によって床暖房する温度（設定床温）の設定が行われ、表示部８７に設定床温に応じた表示がなされる。設定床温の表示は、数値として表示しても良く、また、表２に示されるように、例えば７段階の温度レベルの何れに設定されているかの表示が行われる。
【００５７】
【表２】

なお、温水エアコン１０と床暖房マット１４２が同時に運転される併用暖房時には、表示部８７に設定室温と設定床温の温度レベルの何れか少なくとも一方が表示される。
【００５８】
システムリモコン１３０は、冷暖切替ボタン９５の操作によって運転モードが設定された状態で運転／停止ボタン９１を操作することにより温水エアコン１０ないし床暖房マット１４２の運転開始を指示する操作信号と設定されている運転条件に基づいた操作信号を送出する。この操作信号等が連動コントローラ２０の受信基板１６０に受信される。なお、システムリモコン１３０では、カバー８９を閉じた状態でも、運転／停止ボタン９１の操作が可能となっている。
【００５９】
図６に示されるように、連動コントローラ２０に設けられている温度検出基板１５８には、床温度検出手段としての輻射センサ１６４が設けられている。この輻射センサ１６４は、被測定物から発せられる赤外線を受信して、被測定物の表面温度を１℃程度の誤差範囲で正確に検出できるようになっている。すなわち、図２に示されるように、連動コントローラ２０には、集光レンズ１６６が設けられており、この集光レンズ１６６が向けられている被測定物が表面温度に応じて発する赤外線を輻射センサ１６４によって受光する。
【００６０】
空調システム１１では、床暖房マット１４２によって床暖房が行われているときには連動コントローラ２０に設けている輻射センサ１６４によって、マット１４４の表面温度を床温として検出してコントロール基板１５２へ出力する。なお、集光レンズ１６６と輻射センサ１６４を一体でスイングさせて室内における所定の領域の温度（複数個所の温度）を検出して、検出温度の平均値等を室温として用いても良い。すなわち、輻射センサ１６４によって床温と共に室温を検出するようにしても良い。
【００６１】
図７に示されるように、システムリモコン１３０には、操作パネル８８上にセンサ切替スイッチ９７が設けられている。また、システムリモコン１３０内には、従来のエアコン用のリモコンスイッチと同様に温度センサが内蔵されており、この温度センサによってシステムリモコン１３０の周囲の温度を室温として検出できるようになっている。
【００６２】
空調システム１１では、センサ切替スイッチ９７の操作によってシステムリモコン１３０内の図示しない温度センサ、室内ユニット２２内の室温センサ１２６及び連動コントローラ２０に設けられている輻射センサ１６４の何れかを選択することにより、選択したセンサによって検出する温度を室温として用いて温水エアコン１０の空調能力の制御に用いる。このとき、システムリモコン１３０の表示部８７には、選択されている温度センサを判別可能な表示がなされる。
【００６３】
連動コントローラ２０のマイコン１５０は、システムリモコン１３０から送出された操作信号を受信すると、この操作信号から、室内ユニット２２及び冷媒ユニット２４に対する空調用の操作信号（主に温水エアコン１０の室内ユニット２２と冷媒ユニット２４の運転に関わる操作信号）と、床暖房装置１４０及び熱源ユニット２６に対する温水暖房用の操作信号を分離し、空調用の操作信号が通信Ｉ／Ｆ基板１５６を介してシリアル通信によって室内ユニット２２へ送出される。室内ユニット２２のマイコン１００は、この操作信号等に基づいて温水エアコン１０の作動を制御する。
【００６４】
また、連動コントローラ２０のマイコン１５０は、システムリモコン１３０から受信した操作信号から温水暖房用の操作信号を分離すると、通信Ｉ／Ｆ基板１５４を介して熱源ユニット２６へ出力する。これと共に、マイコン１５０には、熱源ユニット２６及び熱源ユニット２６を用いた床暖房マット１４２の運転状態が、熱源ユニット２６のコントロール基板１７４から通信Ｉ／Ｆ基板１５４へ入力されるようになっており、連動コントローラ２０では、熱源ユニット２６及び床暖房マット１４２の運転状態も室内ユニット２２へ送出するようになっている。すなわち、空調システム１１では、連動コントローラ２０によって温水エアコン１０と床暖房装置１４０が接続されている。
【００６５】
ところで、連動コントローラ２０は、設定床温と輻射センサ１６４によって検出した床温に応じた熱動弁７６の動作ステップを熱源ユニット２６へ出力することにより、床暖房マット１４２の暖房能力を制御している。すなわち、マイコン１５０は、床温が設定床温より低くなっているときには、熱動弁７６のオン時間が長くなるように動作ステップを設定し、床温が設定床温を越えると熱動弁７６のオン時間が短くなるように動作ステップを設定する。これによって、床暖房時の床温が設定床温に保たれるようにしている。
【００６６】
一方、システムリモコン１３０は、冷暖切替ボタン９５の操作によって床暖房マット１４２を単独で運転する「床暖房」モードが選択された状態で、床暖房ボタン９６を操作したときには、「自動」モードと「手動」モードの何れかに切り換えられる。連動コントローラ２０は、「手動」モードに設定されたときには、温度下げボタン９４Ａ及び温度上げボタン９４Ｂの操作によって設定された設定床温に基づいて床暖房を行う。
【００６７】
図６に示されるように、連動コントローラ２０のコントロール基板１５２には、ＥＥＰＲＯＭ等を用いたメモリ１６８が設けられている。このメモリ１６８には、床暖房時に最も快適と感じる床温として設定した温度Ｔsf1 が記憶されており、コントロール基板１５２のマイコン１５０は、床暖房マット１４２を用いて床暖房を行うときに、システムリモコン１３０の床暖房ボタン９６の操作により「自動」モードに設定されると、メモリ１６８に記録されている温度Ｔsf1 を設定床温（設定床温Ｔsf）に設定する。これによって、床温が温度Ｔsf1 となるように床暖房マット１４２による床暖房が制御される。
【００６８】
一方、メモリ１６８には、温水エアコン１０と床暖房マット１４２を併用して暖房を行うときに、設定室温（設定室温Ｔsr）とする温度が記憶されている。連動コントローラ２０のマイコン１５０は、システムリモコン１３０の操作によって、温水エアコン１０と床暖房マット１４２を併用して暖房を行う「暖房・床暖房」モードが選択された状態で、床暖房ボタン９６の操作によって「自動コンフォト」又は「自動エコノミ」が選択されると、このメモリ１６８に記憶している温度を設定室温Ｔsrとして温水エアコン１０へ出力する。すなわち、空調システム１１では、床暖房マット１４２を用いた自動運転では、設定床温Ｔsf及び設定室温Ｔsrを予めメモリ１６８に記憶させている温度に自動的に設定する。
【００６９】
メモリ１６８には、設定室温Ｔsrとする温度として温度Ｔsr1 、Ｔsr2 （Ｔsr1 ＞Ｔsr2 ）を記憶させている。マイコン１５０は、温水エアコン１０と床暖房マット１４２による併用暖房時に「自動コンフォト」モードが選択されることにより温度Ｔsr1 を設定室温Ｔsrとし、「自動エコノミ」モードに選択されることにより、温度Ｔsr1 より低い温度の温度Ｔsr2 を設定室温Ｔsrとする。空調システム１１では、温水エアコン１０による空調暖房時の設定室温Ｔsrを下げることにより省エネを図るようにしている。
【００７０】
なお、本実施の形態では、設定室温Ｔsr及び設定床温Ｔsfとして設定する温度Ｔsr1 、Ｔsr2 、Ｔsf1 を記憶するメモリ１６８を連動コントローラ２０に設けた例として説明するが、メモリ１６８をシステムリモコン１３０に設け、システムリモコン１３０上で自動モード（「自動コンフォト」又は「自動エコノミ」モード）が選択されると、システムリモコン１３０が設定室温Ｔsrないし設定床温Ｔsfとして温度Ｔsr1 、Ｔsr2 、Ｔsf1 を送出するようにしても良い。
【００７１】
一方、「自動コンフォト」及び「自動エコノミ」モードが選択されることにより設定される設定床温Ｔsf及び設定室温Ｔsrは、それぞれシステムリモコン１３０の温度下げボタン９３Ａ、９４Ａ及び温度上げボタン９３Ｂ、９４Ｂ（図７参照）の操作によって所定の範囲で可変可能となっている。
【００７２】
ここで、メモリ１６８に記録される温度Ｔsf1 、Ｔsr1 、Ｔsr2 及びこれらの可変範囲について図８を参照しながら説明する。
【００７３】
床暖房時には、マット１４４上に着座しているときと椅子に座っているときなどでは、床面の温度が同じでも暖房感が少なからず異なる。マット１４４上に着座しているときには、床温が３１℃を越えると低温火傷を生じる恐れがあり、少なくとも床温Ｔf は、３１℃以下である必要があり、３０℃以下であることがより好ましい。また、椅子に座るなどしマット１４４に直接触れていないときには、床温Ｔf を２５℃以上とすることにより暖房不足を感じることがない。また、最も快適な暖房感が得られる温度は、２８℃となっている。
【００７４】
ここから、図８に示されるように、本実施の形態では、温度Ｔsf1 を２８℃とし、温度Ｔsf1 を設定床温Ｔsfに設定したときに、この設定床温Ｔsfを、床暖房を行っているときの床温として大多数の人が暖房不足や暖房の効きすぎと感じることがない温度である２５℃〜３１℃（２８℃±３℃）の間で可変できるようにしている。
【００７５】
一方、床暖房と併用して温水エアコン１０を用いて室内の空調暖房を行うときには、室温Ｔr が低すぎたり高すぎたりすることにより不快感が生じる。また、床温Ｔf と室温Ｔr
従って、床温Ｔf と室温Ｔr の温度差は、１２℃以内（Ｔf −Ｔr ≦１２℃）であることが好ましく、１０℃以内（Ｔf −Ｔr ≦１０℃）であることがより好ましい。また、床暖房と併用して温水エアコン１０によって室内の暖房を図るときには、室温Ｔr が１８℃以上、２３℃以下（１８℃≦Ｔr ≦２３℃）であることが好ましく、これによって、温水エアコン１０により暖房するときの暖房不足感及び暖房の効きすぎ感が生じるのを防止することができる。
【００７６】
さらに、椅子に座るなどしているときには、室温Ｔr が同じでも床温Ｔf が下がることにより暖房不足を感じることがあるので、室温Ｔr 、床温Ｔf が、それぞれ１８℃≦Ｔr ≦２３℃、２５℃≦Ｔf ≦３１℃の範囲では、２・Ｔr −Ｔf≧Ｃ（Ｃは定数）であることが
ここから、図８に示されるように、併用暖房時には、床温Ｔf 及び室温Ｔr が点ａ、ｂ、ｃ、ｄ、ｅ、ｆの領域内、より好ましくは、点ａ、ｂ、ｇ、ｈ、ｆの領域内であることにより、快適な暖房状態と感じられ、暖房不足や暖房の効きすぎ感を生じさせることがない。
【００７７】
一方、併用暖房時に床温が２８℃であるときに、最も快適と感じられる室温は、２１℃（図８に示す点Ｐ）である。ここから、温度Ｔsf１に対して温度Ｔsr1を２１℃として、「自動コンフォト」モードが選択されることにより、設定床温Ｔsf及び設定室温Ｔsrは、それぞれ２８℃、２１℃に設定されるようにしている。
【００７８】
また、暖房運転時には設定温度を下げることにより省エネを測ることができる。ただ、床暖房マット１４２では、床温の変化が緩やかであるために、設定床温Ｔsfを下げたとしても必ずしも顕著な省エネ効果が得られるとは限らない。このため、本実施の形態では、設定室温Ｔsrを下げることにより省エネ効果が得られるようにしており、一例として快適な暖房状態と感じられる領域内で、床温Ｔf が２８℃のときに最も低い室温Ｔr （Ｔr ＝１８．５℃、図８に示す点Ｑ）を温度Ｔsr2 としている。これにより、「自動エコノミ」モードが選択されることにより、設定床温Ｔsf及び設定室温Ｔsrは、それぞれ２８℃、１８．５℃に設定される。
【００７９】
一方、点ａ、ｂ、ｇ、ｈ、ｆ内の領域では、快適な暖房状態が得られるので、「自動コンフォト」及び「自動エコノミ」モード時には、この領域内で設定床温Ｔsf及び設定室温Ｔsrを温度下げボタン９３Ａ、９４Ａ及び温度上げボタン９３Ｂ、９４Ｂの操作によって可変することができるようにしている。なお、設定室温Ｔsrは、温度Ｔsr1 、Ｔsr2 の２段階に設定できるようにしているので、設定室温Ｔsrが温度Ｔsr1 に設定される「自動コンフォト」が選択されているときには、１９℃〜２３℃（±２℃）の範囲で可変できるようにし、設定室温Ｔsrが温度Ｔsr2 に設定される「自動エコノミ」が選択されているときには、１８．５℃〜２１℃（＋２℃）の範囲で可変できるようにしている。
【００８０】
次に本実施の形態の作用を説明する。
【００８１】
空調システム１１では、温水エアコン１０によって空調を行う場合、システムリモコン１３０の操作によって温水エアコン１０の運転モード、設定室温Ｔsr等の運転条件を設定する。システムリモコン１３０は設定された運転条件に応じた操作信号を送出し、この操作信号が連動コントローラ２０によって受信されると、温水エアコン１０は、設定された運転条件に応じた空調運転を開始する。通常、温水エアコン１０は、室温Ｔr をシステムリモコン１３０上で設定した設定室温Ｔsrに保つように空調能力を制御しながら空調する。
【００８２】
一方、床暖房マット１４２は、システムリモコン１３０の操作によって「暖房・床暖房」又は「床暖房」モードに設定されることにより床暖房運転を開始し、床温Ｔf が設定床温Ｔsfとなるように暖房能力が連動コントローラ２０によって制御される。例えば、「手動」モードが選択された状態で温度下げボタン９４Ａ及び温度上げボタン９４Ｂの操作によって設定床温Ｔsfが設定されると、連動コントローラ２０は、マット１４４の表面温度となる床温Ｔf が設定床温Ｔsfとなるように輻射センサ１６４によって検出した床温Ｔf と設定床温Ｔsfに基づいて熱動弁７６の開閉するときのデューテー比（オン時間とオフ時間の比率）を制御する。
【００８３】
これによって、室内は、床温Ｔr がシステムリモコン１３０によって設定した設定床温Ｔsfとなるように暖房され、さらに、この設定床温Ｔsfに保たれる。
【００８４】
ところで、空調システム１０では、「自動」モードでの床暖房が可能となっている。自動モードでの床暖房は、システムリモコン１３０の運転切替ボタン９５の操作によって「床暖房」モードを選択した状態で床暖房ボタン９６を操作して「自動」モード（「自動コンフォト」又は「自動エコノミ」）を選択することにより設定される。
【００８５】
連動コントローラ２０は、自動モードでの床暖房が選択されることにより、メモリ１６８に予め記録している温度Ｔsf1 を設定床温Ｔsfに設定する。この後、連動コントローラ２０は、輻射センサ１６４によって検出する床温Ｔf が設定床温Ｔsfとなるように熱動弁７６の動作ステップを設定する。熱源ユニット２６は、設定された動作ステップに応じたデューテー比で熱動弁７６の開閉を制御する。
【００８６】
すなわち、空調システム１１では、システムリモコン１３０の操作によって自動モードでの床暖房運転が設定されることにより、連動コントローラ２０が設定床温Ｔsfを予め設定されている温度に自動的に設定し、床温Ｔf がこの設定床温Ｔsfとなるように床暖房を行う。
【００８７】
この設定床温Ｔsfとして設定される温度Ｔsf1 は、床暖房を行っているときに、快適な暖房状態と感じる床温となっているため、設定床温Ｔsfを温度下げボタン９４Ａ、温度上げボタン９４Ｂを操作して設定することなく、簡単に快適な暖房状態になる温度に設定することができる。
【００８８】
また、空調システム１１では、自動的に設定床温Ｔsfを設定した状態で、さらに、さらにシステムリモコン１３０の温度下げボタン９４Ａないし温度上げボタン９４Ｂを操作することにより、設定床温Ｔsfを調整することができる。例えば、椅子に座るなどして床面から離れているときには、温度上げボタン９４Ｂを操作して設定床温Ｔsfを上げる。これによって、床面（マット１４４）から離れた位置でも十分な暖房効果が得られる。
【００８９】
また、マット１４４上に着座しているときには、床温Ｔr が温度Ｔsf1 より下がっても十分な暖房効果が得られるので、システムリモコン１３０の温度下げボタン９４Ａを操作して設定床温Ｔsfを下げる。この場合でも、設定床温Ｔsfの調整範囲は、快適な床暖房状態となる範囲内であるために、快適性が損なわれることがないのは勿論、好みに応じた快適な暖房感が得られる。
【００９０】
一方、空調システム１１では、「暖房・床暖房」モードが選択された場合、言い換えれば、温水エアコン１０と床暖房マット１４２の併用運転による暖房を選択した状態で、床暖房ボタン９６を操作して「自動コンフォト」又は「自動エコノミ」モードを選択することにより、設定床温Ｔsfと共に設定室温Ｔsrを、予め設定してメモリ１６８に記憶させている温度に自動的に設定し、室内が設定室温Ｔsr及び設定床温Ｔsfとなるように暖房を行う。
【００９１】
例えば併用運転時に「自動コンフォト」モードが選択されると、連動コントローラ２０のマイコン１５０は、設定床温Ｔsfを温度Ｔsf１に設定すると共に、設定室温Ｔsrを温度Ｔsr1 に設定する。温水エアコン１０は設定室温Ｔsrが温度Ｔsr1 に設定されることにより、室温Ｔr が温度Ｔsr1 となるように暖房運転を行う。
【００９２】
この設定室温Ｔsrに設定する温度Ｔsr1 は、床温Ｔf が設定床温Ｔsfとなっているときに、最も快適と感じる温度としている。このため、併用暖房を行うときに、システムリモコン１３０の温度下げボタン９３Ａ及び温度上げボタン９３Ｂを操作して、設定床温Ｔsfに合わせて設定室温Ｔsrを設定する作業を行うことなく、簡単に快適な暖房状態とすることができる。
【００９３】
また、空調システム１１では、併用暖房時に「自動エコノミ」モードが選択されることにより、連動コントローラ２０は設定床温Ｔsfを温度Ｔsf1 に設定すると共に、設定室温Ｔsrを温度Ｔsr2 に設定する。この温度Ｔsr2 は、床温Ｔf が温度Ｔsf1 となっているときに、快適な暖房状態と感じる領域内で最も低い温度となっている。
【００９４】
一般に暖房を行う場合、設定温度を下げることにより設定温度が高いときに比べてエネルギー消費量を抑えることができる。空調システム１１では、「自動エコノミ」が選択されることにより、併用暖房時に快適と感じる温度領域内で、室温Ｔr を最も低い温度Ｔsr2 とすることにより、快適性を損なうことなく、省エネを図ることができる。
【００９５】
このように、空調システム１１では、温水エアコン１０と床暖房マット１４２の併用運転によって暖房を行うときに自動モードを選択することにより、設定室温Ｔsrと設定床温Ｔsfをそれぞれ快適な暖房状態と感じる室温Ｔr 及び床温Ｔfに設定する。これにより、システムリモコン１３０の温度下げボタン９３Ａ、９４Ａ及び温度上げボタン９３Ｂ、９４Ｂを用いて併用暖房時に快適な暖房状態となるように設定床温Ｔsfを設定すると共に設定床温Ｔsfに基づいて設定室温Ｔsrを設定する操作を行うことなく、設定室温Ｔsr及び設定床温Ｔsfを簡単にかつ適切な温度に設定することができる。
【００９６】
一方、「自動コンフォト」又は「自動エコノミ」モードを選択することにより設定される設定床温及び設定室温のそれぞれは、温度下げボタン９３Ａ、９４Ａ及び温度上げボタン９３Ｂ、９４Ｂの操作によって予め設定されている範囲内で可変することができる。設定室温Ｔsr及び設定床温Ｔsfは、それぞれ併用暖房時に快適な暖房感が得られるように設定されている領域内に限られるため、暖房される室内の快適性を損なうことなく、好みの暖房状態とすることができる。
【００９７】
なお、以上説明した本実施の形態では、本発明の構成を限定するものではない。本実施の形態では、空気調和機と暖房時に温水を用いる温水エアコン１０を用いて説明したが、本発明は、空気調和機として冷凍サイクルを用いて冷暖房を行う一般的な構成の空気調和機を用いても良い。
【００９８】
また、本実施の形態では、設定床温Ｔsfを２８℃として、設定室温Ｔsrを２１℃及び１８．５℃としたが、これに限らず、快適な暖房状態と感じる領域内であれば何れの温度に設定しても良い。また、快適な暖房状態を感じる領域が、気象条件や暖房する室内の条件等の環境条件によって変わるときには、この環境条件に応じて設定床温Ｔsf、設定室温Ｔsrを変えるようにしても良い。すなわち、環境条件等に応じて快適な暖房状態となる室温Ｔr と床温Ｔf の温度範囲を設定し、この温度範囲内で設定室温Ｔsr及び設定床温Ｔsfが設定されるようにしても良い。
【００９９】
さらに、本実施の形態では、設定室温Ｔsrを２段階に設定したが、例えば設定床温Ｔsfも省エネを考慮して２段階以上に設定しても良い。
【０１００】
また、本実施の形態では、床暖房マット１４２と温水エアコン１０の室内ユニット２２とは別に連動コントローラ２０を設けたが、連動コントローラ２０としては、室内ユニット２２と共に室内機１２に内蔵されたものであっても良く、連動コントローラ２０による設定床温Ｔsfを床温Ｔf に基づいた床暖房マット１４２の暖房能力の制御機能を室外機１４に内蔵させても良い。すなわち、温水エアコン１０の室内ユニット２２で設定室温Ｔsrと共に設定床温Ｔsfを設定し、室外機１４（熱源ユニット２６）によって設定床温Ｔf を床温Ｔf に基づいた床暖房マット１４２の暖房能力の制御を行っても良い。

[0001]
The present invention relates to a floor heating device that heats a room from a floor surface with hot water, and a heating system that includes a floor heating device and an air conditioner that performs heating by blowing warm air from an indoor unit.
[Prior art]
[0002]
In recent years, with the spread of air conditioners (hereinafter, referred to as “air conditioners”), indoor heating is often performed by air conditioners. As the air conditioner, there is a hot water air conditioner (hereinafter, referred to as a "hot water air conditioner") that heats a room using hot water, in addition to a general air conditioner that performs a cooling / heating operation by a refrigeration cycle using a refrigerant.
[0003]
In a hot water air conditioner, a hot water heat exchanger (radiator) is provided in a room unit together with a heat exchanger (evaporator) for a refrigerant used for cooling, and hot water generated by a heat source unit disposed outside the room is used for the indoor unit. By circulating between the radiator and the radiator, the air that passes through the radiator and is blown into the room is heated and heated. In such a hot water air conditioner, in addition to the so-called manual operation mode in which the set temperature, as well as the air volume, the air direction, etc. are set as desired, an automatic air conditioner that controls the air volume, the air direction, and the air conditioning capacity so that the room reaches the set room temperature. An operation mode is provided.
[0004]
on the other hand,Floor heatingExamples of the apparatus include a floor heating mat for heating the room from the floor by circulating hot water into a hot water tube laid on the floor. Some floor heating mats can change the heating capacity to three levels, for example, "high", "medium", and "low".(For example, refer to JP-A-11-237058)The duty ratio, which is the ratio between the ON time and the OFF time when circulating hot water within a predetermined time, is changed according to the selected heating capacity. That is, when set to "low", the heating capacity is reduced by changing the duty ratio so that the on-time, which is the time during which hot water is circulated, is shortened, and when set to "high", the on-time Change the duty ratio to increase the heating capacity.
[0005]
Further, the floor heating mat detects the temperature of the floor surface to be heated, and changes the duty ratio based on the temperature difference between the detected temperature and the set temperature (set floor temperature). Can be kept.
[0006]
By the way, in the floor heating mat that performs floor heating based on the set floor temperature, the floor surface temperature can be set according to preference, but when the set floor temperature does not reach the desired temperature when starting floor heating, An operation to change the set bed temperature is required. Further, in floor heating using hot water, it is difficult to determine whether or not the set temperature matches the taste because the temperature change is gradual, and it takes time to heat to the desired temperature.
[0007]
On the other hand, when heating is performed by using the hot water air conditioner and the floor heating mat together, the temperature is set separately for each of the hot water air conditioner and the floor heating mat. For this reason, when heating is performed using a hot water air conditioner and a floor heating mat together, for example, if the temperature difference between the floor surface temperature and the room temperature is large or the room temperature is higher than the floor temperature, discomfort occurs. In order to prevent such a problem, for example, an operation such as setting a set room temperature in accordance with a set floor temperature is required, and the operation of setting operating conditions becomes cumbersome.
[Problems to be solved by the invention]

According to the first aspect of the present invention,The selection means selects one of the temperature set by the temperature setting means and the temperature stored in the storage means as the set bed temperature. The storage unit stores a temperature in a predetermined temperature range.
[0011]
The temperature stored in the storage unit is preferably a floor temperature at which an appropriate heating state is felt when floor heating is performed, and more preferably a floor temperature at which an optimum heating state is felt. Thus, by selecting the temperature stored in the storage means as the set floor temperature, it is possible to easily perform appropriate floor heating without causing a floor heating state in which it is felt that heating is insufficient or heating is too effective. .
[0012]
Also,When the temperature stored in the storage means is selected as the set bed temperature by the selection means,By changing the temperature stored in the storage means by the adjustment means, a predetermined predeterminedIn the temperature rangeAny temperature can be set as the set bed temperature.
[0013]
By setting the predetermined temperature range to a temperature range in which an appropriate heating state is felt when floor heating is performed, it is possible to cause a feeling of insufficient heating or excessive heating when floor heating is performed. The desired floor temperature can be set within a range that does not have an appropriate heating state.
[0014]
The invention according to claim 2 is an air conditioner that air-conditions and heats the room by setting the room temperature to a set room temperature by blowing air heated by hot water circulating in a radiator provided in the indoor unit to the room, and a floor surface. A floor heating device that circulates hot water through hot water pipes laid in the floor to heat the floor so that the floor temperature becomes the set floor temperature, and a set room temperature and a set floor temperature. A room temperature setting means and a floor warm temperature setting means capable of setting each of the temperature to an arbitrary temperature, a storage means for storing a temperature in a predetermined temperature range predetermined as a set room temperature and a set floor temperature, respectively, Selection means for selecting and setting one of the temperature set by the setting means and the floor warm temperature setting means and the temperature stored in the storage means as the set room temperature and the set floor temperature, A predetermined temperature and a temperature different from the predetermined temperature within the predetermined temperature range are stored as the set room temperature or the set floor temperature in the storage unit, and the stored temperatures are stored.

thisClaim 2According to the invention, when performing combined heating using the air conditioner and the floor heating device, the temperature stored in the storage unit can be selected and set as the set room temperature and the set floor temperature by the selection unit.
[0016]
The temperature stored in the storage means is a temperature at which the set floor temperature is felt as an appropriate heating state or an optimum heating state when floor heating is performed, and the set room temperature is used in combination with floor heating. When heating by an air conditioner, the temperature is set to a temperature at which an appropriate room temperature is felt or a temperature at which an optimum room temperature is felt. Thus, the optimum heating state can be achieved by combining the floor temperature and the room temperature without performing a troublesome operation of setting the set room temperature and the set floor temperature in consideration of the mutual temperatures during the combined heating.
[0017]
Also,According to the present invention, for example, a plurality of temperatures that become the set room temperature are stored in the storage unit, and any one of the plurality of temperatures is selected and set. If the set room temperature is different, the heating capacity is also different, and by setting the set room temperature to a low temperature, the amount of energy required for heating is reduced.
[0018]
Therefore, with a simple operation selected by the selecting means, when one temperature is set to the set room temperature, the optimal heating state can be obtained, and when the other temperature is set to the set room temperature, the appropriate heating state can be obtained. It can be in a heating state where an energy saving effect can be obtained.

The adjustment range of the temperature at which the set floor temperature is reached is a range in which the floor temperature when performing floor heating is felt to be in an appropriate heating state, and the temperature at which the set room temperature is reached is a temperature range in which the floor temperature is felt to be in an appropriate heating state. During the combined heating with floor heating as described above, the room temperature is set to a temperature range in which an appropriate heating state is felt.
[0020]
Thus, with a simple operation selected by the selection means, a desired heating state is set within a range in which the user does not feel discomfort due to a temperature difference between the room temperature and the floor temperature or the like, insufficient heating, excessive heating, or the like during combined heating. be able to.

In the air conditioning system 11, when the floor heating is performed by the floor heating mat 142, the surface temperature of the mat 144 is detected as the floor temperature by the radiation sensor 164 provided in the interlocking controller 20 and output to the control board 152. In addition, the condensing lens 166 and the radiation sensor 164 are integrally swung.IndoorsAlternatively, the temperature of a predetermined region (the temperature at a plurality of locations) may be detected, and the average of the detected temperatures may be used as the room temperature. That is, the radiation sensor 164 may detect the room temperature together with the floor temperature.
[0061]
As shown in FIG. 7, the system remote controller 130 is provided with a sensor changeover switch 97 on the operation panel 88. The system remote controller 130 has a built-in temperature sensor similar to a conventional remote control switch for an air conditioner, and the temperature sensor can detect the temperature around the system remote controller 130 as room temperature.
[0062]
In the air conditioning system 11, by operating the sensor changeover switch 97, a temperature sensor (not shown) in the system remote controller 130, a room temperature sensor 126 in the indoor unit 22, and a radiation sensor 164 provided in the interlocking controller 20 are selected. The temperature detected by the selected sensor is used as the room temperature to control the air conditioning capacity of the hot water air conditioner 10. At this time, a display is provided on the display unit 87 of the system remote controller 130 so that the selected temperature sensor can be determined.
[0063]
When the microcomputer 150 of the interlocking controller 20 receives the operation signal transmitted from the system remote controller 130, the microcomputer 150 uses the operation signal to perform an air conditioning operation signal for the indoor unit 22 and the refrigerant unit 24 (mainly the indoor unit 22 of the hot water air conditioner 10 and the An operation signal related to the operation of the refrigerant unit 24) and an operation signal for hot water heating for the floor heating device 140 and the heat source unit 26 are separated, and an operation for air conditioning is performed.SignalTransmission to the indoor unit 22 by serial communication via the communication I / F board 156Is done.The microcomputer 100 of the indoor unit 22 controls the operation of the hot water air conditioner 10 based on the operation signal and the like.
[0064]
When the microcomputer 150 of the interlocking controller 20 separates the operation signal for hot water heating from the operation signal received from the system remote controller 130, the microcomputer 150 outputs the operation signal to the heat source unit 26 via the communication I / F board 154. At the same time, the microcomputer 150 inputs the heat source unit 26 and the operating state of the floor heating mat 142 using the heat source unit 26 from the control board 174 of the heat source unit 26 to the communication I / F board 154. In the interlocking controller 20, the operating states of the heat source unit 26 and the floor heating mat 142 are also sent to the indoor unit 22. That is, in the air conditioning system 11, the hot water air conditioner 10 and the floor heating device 140 are connected by the interlocking controller 20.
[0065]
By the way, the interlocking controller 20 controls the heating capacity of the floor heating mat 142 by outputting to the heat source unit 26 an operation step of the thermal valve 76 corresponding to the set floor temperature and the floor temperature detected by the radiation sensor 164. I have. That is, when the bed temperature is lower than the set bed temperature, the microcomputer 150 sets the operation steps so that the on-time of the thermal valve 76 becomes longer, and when the bed temperature exceeds the set bed temperature, the thermal valve 76 The operation steps are set so that the ON time of is shortened. This allows the floor temperature during floor heating to reach the set floor temperature.KeptLike that.
[0066]
On the other hand, the system remote controller 130ThereforeWhen the floor heating button 96 is operated in a state where the “floor heating” mode in which the floor heating mat 142 operates alone is selected, the mode is switched to either the “automatic” mode or the “manual” mode. When set to the "manual" mode, the interlocking controller 20 performs floor heating based on the set floor temperature set by operating the temperature lowering button 94A and the temperature raising button 94B.
[0067]
As shown in FIG. 6, the control board 152 of the interlocking controller 20 is provided with a memory 168 using an EEPROM or the like. The memory 168 stores a temperature Tsf1 set as the floor temperature that is most comfortable when the floor is heated. The microcomputer 150 of the control board 152 uses the system remote control when performing floor heating using the floor heating mat 142. When the "automatic" mode is set by operating the floor heating button 96 of 130, the temperature Tsf1 recorded in the memory 168 is set to the set floor temperature (set floor temperature Tsf). Thus, the floor heating by the floor heating mat 142 is controlled so that the floor temperature becomes the temperature Tsf1.
[0068]
On the other hand, the memory 168 stores a temperature at a set room temperature (set room temperature Tsr) when heating is performed using the hot water air conditioner 10 and the floor heating mat 142 together. The microcomputer 150 of the interlocking controller 20 operates the floor heating button 96 in a state in which the “heating / floor heating” mode for performing heating using the hot water air conditioner 10 and the floor heating mat 142 in combination is selected by operating the system remote controller 130. When "automatic photo" or "automatic economy" is selected, the temperature stored in the memory 168 is output to the hot water air conditioner 10 as the set room temperature Tsr. That is, in the automatic operation using the floor heating mat 142, the air conditioning system 11 automatically sets the set floor temperature Tsf and the set room temperature Tsr to the temperatures stored in the memory 168 in advance.
[0069]
In the memory 168, temperatures Tsr1 and Tsr2 (Tsr1> Tsr2) are stored as temperatures to be set room temperature Tsr. The microcomputer 150 sets the temperature Tsr1 to the set room temperature Tsr by selecting the “automatic photo mode” during the combined heating by the hot water air conditioner 10 and the floor heating mat 142, and sets the temperature Tsr1 by selecting the “automatic economy” mode. A lower temperature Tsr2 is set as a set room temperature Tsr. In the air conditioning system 11, the hot water air conditioner 10Air conditioning and heatingEnergy saving is achieved by lowering the set room temperature Tsr at the time.
[0070]
In the present embodiment, the memory 168 for storing the temperatures Tsr1, Tsr2, and Tsf1 set as the set room temperature Tsr and the set floor temperature Tsf is described as an example provided in the interlocking controller 20, but the memory 168 is provided in the system remote controller 130. When an automatic mode ("automatic photo" or "auto economy" mode) is selected on the system remote controller 130, the system remote controller 130 sends out the temperatures Tsr1, Tsr2, and Tsf1 as the set room temperature Tsr or the set floor temperature Tsf. You may do it.
[0071]
On the other hand, the set floor temperature Tsf and the set room temperature Tsr that are set by selecting the “automatic photo” mode and the “automatic economy” mode are respectively set to the temperature lowering buttons 93A and 94A and the temperature raising buttons 93B and 94B of the system remote controller 130. It can be changed within a predetermined range by the operation of (see FIG. 7).
[0072]
Here, the temperatures Tsf1, Tsr1, Tsr2 recorded in the memory 168 and their variable ranges will be described with reference to FIG.
[0073]
At the time of floor heating, when sitting on the mat 144 and sitting on a chair, etc., even if the temperature of the floor surface is the same, the feeling of heating is considerably different. When sitting on the mat 144, if the floor temperature exceeds 31 ° C, a low-temperature burn may occur. At least the floor temperature Tf needs to be 31 ° C or lower, and more preferably 30 ° C or lower. . When the user does not directly touch the mat 144 by sitting in a chair or the like and setting the floor temperature Tf to 25 ° C. or higher, the user does not feel insufficient heating. The temperature at which the most comfortable heating feeling is obtained is 28 ° C.
[0074]
From this, as shown in FIG. 8, in the present embodiment, when the temperature Tsf1 is set to 28 ° C. and the temperature Tsf1 is set to the set floor temperature Tsf, floor heating is performed with the set floor temperature Tsf. The floor temperature at this time can be varied between 25 ° C. and 31 ° C. (28 ° C. ± 3 ° C.), which is a temperature at which the majority of people do not feel that heating is insufficient or heating is too effective.
[0075]
On the other hand, using the hot water air conditioner 10 in combination with floor heatingAir conditioning and heatingIs performed, the discomfort occurs because the room temperature Tr is too low or too high. Also, the floor temperature Tf and the room temperature Tr
Therefore, the temperature difference between the bed temperature Tf and the room temperature Tr is preferably within 12 ° C. (Tf−Tr ≦ 12 ° C.), and more preferably within 10 ° C. (Tf−Tr ≦ 10 ° C.). When the interior of the room is heated by the hot water air conditioner 10 in combination with the floor heating, the room temperature Tr is preferably 18 ° C. or more and 23 ° C. or less (18 ° C. Tr ≦ 23 ° C.). Accordingly, it is possible to prevent a feeling of insufficient heating and a feeling of excessive heating when heating from being generated.
[0076]
Further, when sitting in a chair or the like, even if the room temperature Tr is the same, the user may feel insufficient heating due to a decrease in the floor temperature Tf, so that the room temperature Tr and the floor temperature Tf are 18 ° C ≦ Tr ≦ 23 ° C and 25 ° C, respectively. In the range of ° C ≦ Tf ≦ 31 ° C., 2 · Tr−Tf ≧ C (C is a constant).
From this, as shown in FIG. 8, during the combined heating, the floor temperature Tf and the room temperature Tr are within the range of the points a, b, c, d, e, and f, and more preferably, the points a, b, g, and h. , F, the user feels a comfortable heating state, and does not cause a feeling of insufficient heating or excessive heating.
[0077]
On the other hand, when the floor temperature is 28 ° C. during combined heating, the room temperature at which the user feels most comfortable is 21 ° C. (point P shown in FIG. 8). From here, the temperature Tsf1 is set to 21 ° C., and the “automatic con photo” mode is selected, so that the set floor temperature Tsf and the set room temperature Tsr are set to 28 ° C. and 21 ° C., respectively. ing.
[0078]
Further, energy saving can be measured by lowering the set temperature during the heating operation. However, in the floor heating mat 142, since the floor temperature changes slowly, even if the set floor temperature Tsf is lowered, a remarkable energy saving effect is not always obtained. Therefore, in the present embodiment, an energy saving effect can be obtained by lowering the set room temperature Tsr.So thatAs an example, in a region where a comfortable heating state is felt, the lowest room temperature Tr (Tr = 18.5 ° C., point Q shown in FIG. 8) when the floor temperature Tf is 28 ° C. is set as the temperature Tsr2. Thus, when the “automatic economy” mode is selected, the set floor temperature Tsf and the set room temperature Tsr are set to 28 ° C. and 18.5 ° C., respectively.
[0079]
On the other hand, in the areas within the points a, b, g, h, and f, a comfortable heating state is obtained. Therefore, in the “automatic photo” and “automatic economy” modes, the set floor temperature Tsf and the set room temperature are set within these areas. Tsr can be changed by operating the temperature lowering buttons 93A and 94A and the temperature raising buttons 93B and 94B. Since the set room temperature Tsr can be set in two stages of temperatures Tsr1 and Tsr2, when "automatic photo" in which the set room temperature Tsr is set to the temperature Tsr1 is selected, 19 ° C to 23 ° C. (± 2 ° C.), and when “automatic economy” in which the set room temperature Tsr is set to the temperature Tsr2 is selected, it can be changed within a range of 18.5 ° C. to 21 ° C. (+ 2 ° C.). Like that.
[0080]
Next, the operation of the present embodiment will be described.
[0081]
In the air conditioning system 11, when air conditioning is performed by the hot water air conditioner 10, operating conditions such as the operation mode of the hot water air conditioner 10 and the set room temperature Tsr are set by operating the system remote controller 130. The system remote controller 130 sends out an operation signal according to the set operation condition, and when the operation signal is received by the interlocking controller 20, the hot water air conditioner 10 starts the air conditioning operation according to the set operation condition. Normally, the hot-water air conditioner 10 performs air conditioning while controlling the air conditioning capacity so as to maintain the room temperature Tr at the set room temperature Tsr set on the system remote controller 130.
[0082]
On the other hand, the floor heating mat 142 is set to the “heating / floor heating” or the “floor heating” mode by operating the system remote controller 130.Floor heatingThe operation is started, and the heating capacity is controlled by the interlocking controller 20 so that the floor temperature Tf becomes the set floor temperature Tsf. For example, when the set floor temperature Tsf is set by operating the temperature lowering button 94A and the temperature raising button 94B in the state where the “manual” mode is selected, the interlocking controller 20 sets the floor temperature Tf, which is the surface temperature of the mat 144, to The duty ratio (the ratio between the on-time and the off-time) when opening and closing the thermal valve 76 is controlled based on the floor temperature Tf detected by the radiation sensor 164 and the set floor temperature Tsf so as to become the set floor temperature Tsf.
[0083]
As a result, the room is heated so that the floor temperature Tr becomes the set floor temperature Tsf set by the system remote controller 130, and is further maintained at the set floor temperature Tsf.
[0084]
By the way, in the air conditioning system 10, floor heating in the "automatic" mode is possible. The floor heating in the automatic mode is performed by operating the floor heating button 96 in a state where the “floor heating” mode is selected by operating the operation switching button 95 of the system remote controller 130 (“automatic photo” or “automatic Economy ").
[0085]
When the floor heating in the automatic mode is selected, the interlocking controller 20 sets the temperature Tsf1 previously recorded in the memory 168 to the set floor temperature Tsf. Thereafter, the interlocking controller 20 sets the operation steps of the thermal valve 76 so that the floor temperature Tf detected by the radiation sensor 164 becomes the set floor temperature Tsf. The heat source unit 26 controls the opening and closing of the thermal valve 76 at a duty ratio according to the set operation step.
[0086]
That is, in the air conditioning system 11, when the floor heating operation in the automatic mode is set by the operation of the system remote controller 130, the interlocking controller 20 automatically sets the set floor temperature Tsf to a preset temperature, and Floor heating is performed so that the temperature Tf becomes the set floor temperature Tsf.
[0087]
The temperature Tsf1, which is set as the set floor temperature Tsf, is a floor temperature at which the user feels a comfortable heating state during floor heating. Therefore, the set floor temperature Tsf is set to the temperature lowering button 94A and the temperature raising button 94B. It is possible to easily set the temperature to a comfortable heating state without setting by operating.
[0088]
In the air-conditioning system 11, while the set floor temperature Tsf is automatically set, the set floor temperature Tsf is adjusted by further operating the temperature lowering button 94A or the temperature raising button 94B of the system remote controller 130. Can be. For example, when the user is away from the floor surface, such as sitting on a chair, the user operates the temperature increase button 94B to increase the set floor temperature Tsf. As a result, a sufficient heating effect can be obtained even at a position away from the floor surface (mat 144).
[0089]
When the user is sitting on the mat 144, a sufficient heating effect can be obtained even if the floor temperature Tr falls below the temperature Tsf1, so that the set floor temperature Tsf is lowered by operating the temperature lowering button 94A of the system remote controller 130. Even in this case, the adjustment range of the set floor temperature Tsf is within a range in which a comfortable floor heating state is achieved, so that comfort is not impaired, and a comfortable feeling of heating according to taste can be obtained. .
[0090]
On the other hand, in the air conditioning system 11, when the "heating / floor heating" mode is selected, in other words, the floor heating button 96 is operated by operating the heating by the combined use of the hot water air conditioner 10 and the floor heating mat 142. By selecting the “automatic photo” or “automatic economy” mode, the set room temperature Tsr together with the set floor temperature Tsf is automatically set to the temperature previously set and stored in the memory 168. Heating is performed so as to reach Tsr and the set floor temperature Tsf.
[0091]
For example, when the "automatic photo" mode is selected during the combined operation, the microcomputer 150 of the interlocking controller 20 sets the set floor temperature Tsf to the temperature Tsf1 and sets the set room temperature Tsr to the temperature Tsr1. The set temperature Tsr is set to the temperature Tsr1 to perform the heating operation such that the room temperature Tr becomes the temperature Tsr1.
[0092]
The temperature Tsr1 set to the set room temperature Tsr is a temperature at which the user feels most comfortable when the floor temperature Tf is equal to the set floor temperature Tsf. Therefore, when performing the combined heating, it is easy and comfortable to operate the temperature lowering button 93A and the temperature raising button 93B of the system remote controller 130 to set the set room temperature Tsr in accordance with the set floor temperature Tsf. Heating state.
[0093]
In the air conditioning system 11, when the "automatic economy" mode is selected during the combined heating, the interlocking controller 20 sets the set floor temperature Tsf to the temperature Tsf1 and sets the set room temperature Tsr to the temperature Tsr2. This temperature Tsr2 is the lowest temperature in a region where a comfortable heating state is felt when the floor temperature Tf is the temperature Tsf1.
[0094]
Generally, when heating is performed, energy consumption can be reduced by lowering the set temperature compared to when the set temperature is high. In the air-conditioning system 11, by selecting “automatic economy”, the room temperature Tr is set to the lowest temperature Tsr2 within the temperature range in which the user feels comfortable during combined heating, thereby saving energy without sacrificing comfort. Can be.
[0095]
As described above, in the air conditioning system 11, by selecting the automatic mode when heating by the combined operation of the hot water air conditioner 10 and the floor heating mat 142, the set room temperature Tsr and the set floor temperature Tsf are each felt as a comfortable heating state. The room temperature Tr and the bed temperature Tf are set. As a result, the set floor temperature Tsf is set using the temperature lowering buttons 93A and 94A and the temperature raising buttons 93B and 94B of the system remote controller 130 so as to provide a comfortable heating state during combined heating, and is set based on the set floor temperature Tsf. The set room temperature Tsr and the set bed temperature Tsf can be easily and appropriately set without performing the operation of setting the room temperature Tsr.
[0096]
On the other hand, the set floor temperature and the set room temperature, which are set by selecting the “automatic photo” or “automatic economy” mode, are preset by operating the temperature decrease buttons 93A and 94A and the temperature increase buttons 93B and 94B. It can be varied within the range. Since the set room temperature Tsr and the set floor temperature Tsf are each limited to an area set so that a comfortable feeling of heating can be obtained during combined heating, a desired heating state can be achieved without impairing the comfort of the room to be heated. It can be.
[0097]
The present embodiment described above does not limit the configuration of the present invention. Although the present embodiment has been described using the air conditioner and the hot water air conditioner 10 that uses hot water for heating, the present invention relates to an air conditioner having a general configuration that performs cooling and heating using a refrigeration cycle as the air conditioner. May be used.
[0098]
In the present embodiment, the set floor temperature Tsf is set to 28 ° C., and the set room temperature Tsr is set to 21 ° C. and 18.5 ° C. However, the present invention is not limited to this. The temperature may be set. Further, when the area where a comfortable heating state is felt changes depending on environmental conditions such as weather conditions and indoor conditions for heating, the set floor temperature Tsf and the set room temperature Tsr may be changed according to the environmental conditions. That is, the temperature range of the room temperature Tr and the floor temperature Tf for providing a comfortable heating state may be set according to environmental conditions and the like, and the set room temperature Tsr and the set floor temperature Tsf may be set within this temperature range.
[0099]
Further, in the present embodiment, the set room temperature Tsr is set in two steps, but for example, the set floor temperature Tsf may be set in two or more steps in consideration of energy saving.
[0100]
Further, in the present embodiment, the interlocking controller 20 is provided separately from the floor heating mat 142 and the indoor unit 22 of the hot water air conditioner 10, but the interlocking controller 20 is built in the indoor unit 12 together with the indoor unit 22. The outdoor unit 14 may have a function of controlling the heating capacity of the floor heating mat 142 based on the set floor temperature Tsf by the interlocking controller 20 based on the floor temperature Tf. That is, the set floor temperature Tsf is set together with the set room temperature Tsr in the indoor unit 22 of the hot water air conditioner 10, and the set floor temperature Tf is set by the outdoor unit 14 (heat source unit 26) to the heating capacity of the floor heating mat 142 based on the floor temperature Tf. Control may be performed.
