実施の形態１．
以下、この発明の実施の形態１を図面を参照して説明する。
図１は、この発明の実施の形態１を示す図で、空気調和機のブロック図である。冷専機／冷暖機一体型空調機の室内機１０１と空調機の室外機［冷暖機種］１１１を据え付けて元電源を投入する前に、プログラム切り替え手段の一例としての冷専機種／冷暖機種切り替え装置である冷専機種／冷暖機種切り替えスイッチ１０５を冷暖房機種に設定し、その後に元電源を入れる。冷専機種／冷暖機種切り替えスイッチ１０５が冷暖房機種信号を信号解析手段１０４に送信して、その信号を信号解析手段１０４が受信し解析して、冷暖房機種信号をマイクロコンピュータ１０７へ送信し、マイクロコンピュータ１０７が正しく信号を受信すると、冷専機／冷暖機一体型空調機の室内機１０１が冷暖房機種になる。
【００１３】
次に、ワイヤレスリモコン１０２から運転動作信号を送信すると、ワイヤレスリモコン信号受信手段１０３が運転動作信号を受信して、信号解析手段１０４に送信する。信号解析手段１０４が運転動作信号を受信して解析を行い、マイクロコンピュータ１０７へ運転動作信号を送信し受信した後に、冷専機／冷暖機一体型空調機の室内機１０１内に異常がないことをマイクロコンピュータ１０７が判断すると、ワイヤレスリモコン１０２から送られた信号と同じ動作を冷専機／冷暖機一体型空調機の室内機１０１が行う。
【００１４】
元電源投入後から、３分以上経過すれば、マイクロコンピュータ１０７が圧縮機動作信号を信号解析手段１０８に送信して、信号解析手段１０８が圧縮機動作信号を解析して正しい信号ならば、冷暖機種信号送受信手段［シリアル信号］１０９へ信号を送り、冷暖機種信号送受信手段［シリアル信号］１０９が空調機の室内機／室外機接続線（以下、接続線）へ圧縮機動作信号を送り、信号が空調機の室外機［冷暖機種］１１１の冷暖機種信号受信手段［シリアル信号］１１２へ送信される。その信号を冷暖機種信号受信手段［シリアル信号］１１２が受信して、信号解析手段１１４へ送信し、信号解析手段１１４が受信及び解析を行い、マイクロコンピュータ１１５へ信号を送信する。その信号をマイクロコンピュータ１１５が受信した後に、空調機の室外機［冷暖機種］１１１内に異常がないことをマイクロコンピュータ１１５が判断すると、圧縮機動作信号送受信手段１１６へ圧縮機動作信号を送信し、圧縮機動作信号送受信手段１１６が受信して、圧縮機１１７へ圧縮機動作信号を送り、圧縮機１１７が正常に圧縮機動作信号を受信すれば、圧縮機１１７が動作を行う。
【００１５】
また、マイクロコンピュータ１１５が圧縮機動作信号送受信手段１１６へ圧縮機動作信号を送るのと同時に信号解析手段１１４へ室外機動作中信号を送る。その信号を、信号解析手段１１４が解析して、正しい信号で有れば冷暖機種信号受信手段［シリアル信号］１１３へ信号を送る。その信号を冷暖機種信号受信手段［シリアル信号］１１３が受信し接続線へ送信する。信号が接続線を通過して冷暖機種信号送受信手段［シリアル信号］１０９が受信し、信号解析手段１０８へ信号を送る。信号解析手段１０８が信号を解析してマイクロコンピュータ１０７に信号を送信しマイクロコンピュータ１０７が受信して、空調機の室外機［冷暖機種］１１１が正常に動作していることを判断する。
【００１６】
または、試運転スイッチ１０６を押すと、試運転スイッチ１０６から試運転信号を信号解析手段１０４に送信して、その信号を信号解析手段１０４が受信し解析して、マイクロコンピュータ１０７へ試運転信号を送信し受信した後に、冷専機／冷暖機一体型空調機の室内機１０１内に異常がないことをマイクロコンピュータ１０７が判断すると、冷専機／冷暖機一体型空調機の室内機１０１が試運転を行う。
【００１７】
元電源投入後から、３分以上経過すれば、マイクロコンピュータ１０７が圧縮機動作信号を信号解析手段１０８に送信して、信号解析手段１０８が圧縮機動作信号を解析して正しい信号ならば冷暖機種信号送受信手段［シリアル信号］１０９へ信号を送り、冷暖機種信号送受信手段［シリアル信号］１０９が接続線へ圧縮機動作信号を送り、信号が空調機の室外機［冷暖機種］１１１の冷暖機種信号受信手段［シリアル信号］１１２へ送信される。その信号を冷暖機種信号受信手段［シリアル信号］１１２が受信して、信号解析手段１１４へ送信し、信号解析手段１１４が受信及び解析を行い、マイクロコンピュータ１１５へ信号を送信する。その信号をマイクロコンピュータ１１５が受信した後に、空調機の室外機［冷暖機種］１１１内に異常がないことをマイクロコンピュータ１１５が判断すると、圧縮機動作信号送受信手段１１６へ圧縮機動作信号を送信し、圧縮機動作信号送受信手段１１６が受信して、圧縮機１１７へ圧縮機動作信号を送り、圧縮機１１７が正常に圧縮機動作信号を受信すれば、圧縮機１１７が動作を行う。
【００１８】
また、マイクロコンピュータ１１５が圧縮機動作信号送受信手段１１６へ圧縮機動作信号を送るのと同時に信号解析手段１１４へ室外機動作中信号を送る。その信号を、信号解析手段１１４が解析して、正しい信号で有れば冷暖機種信号受信手段［シリアル信号］１１３へ信号を送る。その信号を冷暖機種信号受信手段［シリアル信号］１１３が受信し接続線にへ送信する。信号が接続線を通過して冷暖機種信号送受信手段［シリアル信号］１０９が受信し、信号解析手段１０８へ信号を送る。信号解析手段１０８が信号を解析してマイクロコンピュータ１０７に信号を送信しマイクロコンピュータ１０７が受信して、空調機の室外機［冷暖機種］１１１が正常に動作していることを判断する。
【００１９】
冷専機／冷暖機一体型空調機の室内機１０１に空調機の室外機［冷専機種］１１８を据え付けた場合、元電源を投入する前に、冷専機種／冷暖機種切り替えスイッチ１０５を冷専機種に設定して、その後に元電源を入れる。冷専機種／冷暖機種切り替えスイッチ１０５が冷専機種信号を信号解析手段１０４に送信して、その信号を信号解析手段１０４が受信し解析して、冷専機種信号をマイクロコンピュータ１０７へ送信し、マイクロコンピュータ１０７が正しく信号を受信すると、冷専機／冷暖機一体型空調機の室内機１０１が冷専機種になる。
【００２０】
ワイヤレスリモコン１０２から運転動作信号を送信すると、ワイヤレスリモコン信号受信手段１０３が運転動作信号を受信して、信号解析手段１０４に送信する。信号解析手段１０４が運転動作信号を受信して解析を行い、マイクロコンピュータ１０７へ運転動作信号を送信し受信した後に、冷専機／冷暖機一体型空調機の室内機１０１内に異常がないことをマイクロコンピュータ１０７が判断すると、ワイヤレスリモコン１０２から送られた信号と同じ動作を冷専機／冷暖機一体型空調機の室内機１０１が行う。
【００２１】
元電源投入後から、３分以上経過すれば、マイクロコンピュータ１０７が圧縮機動作信号を信号解析手段１０８に送信して、信号解析手段１０８が圧縮機動作信号を解析して正しい信号ならば冷専機種信号送信手段１１０へ送信する。冷専機種信号送信手段１１０が受信し、空調機の接続線に信号を送信し、信号が接続線を通過すると空調機の室外機［冷専機種］１１８の冷専機種信号受信手段及び信号解析手段１１９が信号を受信して解析して、正しい信号で有れば圧縮機動作信号送信手段１２０へ圧縮機動作信号を送り、圧縮機動作信号送信手段１２０が信号を受信して圧縮機１２１へ信号を送信し、圧縮機１２１が圧縮機動作信号を正しく受信すれば、圧縮機１２１が動作を行うことにより正常の運転を空調機が行う。
【００２２】
冷専機／冷暖機一体型空調機の室内機１０１に、空調機の室外機［冷専機種］１１８を据え付け（接続）た場合、据え付け後に、冷専機／冷暖機一体型空調機の室内機１０１内の冷専機種／冷暖機種切り替えスイッチ１０５をＯＮにして、元電源を投入した場合、信号解析手段１０４にて、冷専機種の認識を行い、マイクロコンピュータ１０７に冷専機種信号を送信し、マイクロコンピュータ１０７が冷専機種の動作を行う。
【００２３】
ワイヤレスリモコンから空調機動作信号［例えば、冷房運転・設定温度２５℃・風速Ｈｉ：この場合室温は２６℃以上とする］を送信すると冷専機／冷暖機一体型空調機の室内機１０１内のワイヤレスリモコン信号受信手段１０３が空調機動作信号を受信した場合、ワイヤレスリモコン信号受信手段１０３が信号解析手段１０４へ空調機動作信号を送り、信号解析手段１０４が空調機動作信号を解析し、正しい信号で有れば、マイクロコンピュータ１０７へ空調機動作信号を送る。マイクロコンピュータ１０７が空調機動作信号を受信し、かつ、電源投入から３分以上経過していて、ファンモータ等が正常に動作していれば、信号解析手段１０８へ冷専機信号を送り、信号解析手段１０８が冷専機信号を受信した場合は、冷専機種信号送信手段１１０へ信号を送り、空調機の室外機［冷専機種］１１８内の冷専機種信号受信手段及び信号解析手段１１９に冷専機種信号を送り、冷専機種信号受信手段及び信号解析手段信号解析手段１１９が受信して信号解析を行い圧縮機動作信号送信手段１２０へ圧縮機動作信号を送る。その信号を圧縮機動作信号送信手段１２０が受信し、圧縮機１２１へ送信し、圧縮機１２１が信号を受信した場合、圧縮機が動作する事によって冷専機種になる。
【００２４】
冷専機／冷暖機一体型空調機の室内機に、空調機の室外機［冷暖機種］１１１を据え付け（接続）た場合、据え付け後に、冷専機／冷暖機一体型空調機の室内機１０１内の冷専機種／冷暖機種切り替えスイッチ１０５をＯＦＦにして、元電源を投入した場合、信号解析手段１０４にて、冷暖機種の認識を行い、マイクロコンピュータ１０７に冷暖機種信号を送信し、マイクロコンピュータ１０７が冷暖機種の動作を行う。
【００２５】
ワイヤレスリモコン１０２から空調機動作信号［例えば、暖房運転・設定温度２５℃・風速Ｈｉ：この場合室温は２４℃以下とする］を送信すると冷専機／冷暖機一体型空調機の室内機１０１内のワイヤレスリモコン信号受信手段１０３が空調機動作信号を受信した場合、ワイヤレスリモコン信号受信手段１０３が信号解析手段１０４へ空調機動作信号を送り、信号解析手段１０４が空調機動作信号を解析し、正しい信号で有れば、マイクロコンピュータ１０７へ空調機動作信号を送る。マイクロコンピュータ１０７が空調機動作信号を受信し、かつ、電源投入から３分以上経過していて、ファンモータ等が正常に動作していれば、信号解析手段１０８へ冷暖機種信号を送り、信号解析手段１０８が冷暖機種信号を受信した場合は、冷暖機種信号送受信手段１０９へシリアル信号を送り、空調機の室外機［冷暖機種］１１１内の冷暖機種信号受信手段［シリアル信号］１１２へシリアル信号を送り、信号解析手段１１４がシリアル信号を受信して正常の信号で有れば、マイクロコンピュータ１１５へシリアル信号を送信する。マイクロコンピュータ１１５がシリアル信号を受信して、空調機が正しく運転できる条件で有れば、圧縮機動作信号送受信手段１１６へ圧縮機動作信号を送信し、圧縮機動作信号送受信手段１１６が圧縮機１１７へ動作信号を送信して、圧縮機１１７が信号を受信した場合、圧縮機１１７が動作する事によって冷暖機種になる。
【００２６】
以上で、冷専機種又は冷暖機種が正常に動作をするが、仮に空調機の室外機［冷暖機種］１１１を冷専機／冷暖機一体型空調機の室内機１０１に接続［据え付け］をして冷専機種／冷暖機種切り替えスイッチ１０５を間違えてＯＮにして元電源を投入した場合、信号解析手段１０４にて、冷専機種の認識を行い、マイクロコンピュータ１０７に冷専機種信号を送信しマイクロコンピュータ１０７が冷専機種と判別することによって、シリアル通信が行われないため、マイクロコンピュータ１１５が異常と判断し圧縮機１１７を動作させないことにより正常運転にはならない（この場合には、冷専機種とマイクロコンピュータ１１５が判別しているため、室内機の表示モニタに異常表示はされない。しかし、圧縮機１１７が動作せずに空調が行われないので、異常と判断できる）。
【００２７】
また、空調機の室外機［冷専機種］１１８を冷専機／冷暖機一体型空調機の室内機１０１に接続［据え付け］して冷専機種／冷暖機種切り替えスイッチ１０５を間違えてＯＦＦにして元電源を投入した場合、信号解析手段１０４にて、冷暖機種の認識を行い、マイクロコンピュータ１０７に冷暖機種信号を送信しマイクロコンピュータ１０７が冷暖機種と判別することによって、空調機の室外機［冷専機］１１８にシリアル信号を送るが、シリアル通信が返却されてこないため、マイクロコンピュータ１０７が異常と判断して、冷専機／冷暖機一体型空調機の室内機１０１の表示モニタに異常表示を行うことによって間違え防止を行う。
【００２８】
上述の動作を、図２のフローチャートで説明する。先ず、ステップ２０２で、冷専機／冷暖機一体型空調機の室内機に、空調機の室外機を接続［据え付け］を行う。ステップ２０３で室外機が冷専機種であるかを判断し、冷専機の場合、ステップ２０４で冷専機／冷暖機一体型空調機の室内機の制御装置の冷専機種／冷暖機種切り替えスイッチＯＮにする。その後、ステップ２０５で元電源投入［定格電圧投入］をする事によって、空調機→冷専機種となる（ステップ２０６）。その後、リモコンから空調機正常動作信号を送り、冷専機／冷暖機一体型空調機の室内機の制御装置がリモコン信号を正しく受信し、かつ元電源投入後３分経過した場合、空調機の室外機（冷専機種）内の圧縮機が動作をして、空調機正常動作になる（ステップ２１０）。
【００２９】
空調機の室外機が冷暖機種の場合には、ステップ２０３における室外機が冷専機種であるかの判断で、冷暖機種のため「ＮＯ」となり、ステップ２０７で冷専機／冷暖機一体型空調機の室内機の制御装置の冷専機種／冷暖機種切り替えスイッチをＯＦＦにする。その後、ステップ２０８で元電源投入［定格電圧投入］をする事によって、空調機→冷暖機種となる（ステップ２０９）。その後、リモコンから空調機正常動作信号を送り、冷専機／冷暖機一体型空調機の室内機の制御装置がリモコン信号を正しく受信し、かつ元電源投入後３分経過した場合、空調機の室外機（冷専機種）内の圧縮機が動作をして、空調機正常動作になる（ステップ２１０）。
【００３０】
以上のように、この実施の形態によれば、冷専機種と冷暖機種の空調機の室内機（制御装置を含む）を一体型したので、製造者が共通化を図れるため、大量生産をすることが出き、コストの削減につながる。また、サービス部品を一本化に出来るため、管理形態が簡素化する事が出き、かつ、据え付け業者が室外機と室内機のセットを間違えることがないため、管理が簡素化できる効果が得られる。
【００３１】
実施の形態２．
以下、この発明の実施の形態２を図面を参照して説明する。
図３は、この発明の実施の形態２を示す図で、空気調和機のブロック図である。冷専機／冷暖機一体型空調機の室内機３０１と空調機の室外機［冷暖機種］３１１を据え付けて、元電源を投入する。ワイヤレスリモコン３０２から冷暖機種信号と運転動作信号を送信すると、ワイヤレスリモコン信号受信手段３０３が冷暖機種信号と運転動作信号を受信して、信号解析手段３０４に送信する。信号解析手段３０４が冷暖機種信号と運転動作信号を受信して解析を行い、マイクロコンピュータ３０７へ冷暖機種信号と運転動作信号を送信し、マイクロコンピュータ３０７が信号を受信した後に、冷専機／冷暖機一体型空調機の室内機３０１が冷暖機種と判断するのと同時に冷専機／冷暖機一体型空調機の室内機３０１内に異常がないことをマイクロコンピュータ３０７が判断すると、ワイヤレスリモコン３０２から送られた信号と同じ動作を冷専機／冷暖機一体型空調機の室内機３０１が行う。
【００３２】
元電源投入後から、３分以上経過すれば、マイクロコンピュータ３０７が圧縮機動作信号を信号解析手段３０８に送信して、信号解析手段３０８が圧縮機動作信号を解析して正しい信号ならば冷暖機種信号送受信手段［シリアル信号］３０９へ信号を送り、冷暖機種信号送受信手段［シリアル信号］３０９が接続線へ圧縮機動作信号を送り、信号が空調機の室外機［冷暖機種］３１１の冷暖機種信号受信手段［シリアル信号］３１２へ送信される。その信号を冷暖機種信号受信手段［シリアル信号］３１２が受信して、信号解析手段３１４へ送信し、信号解析手段３１４が受信及び解析を行い、マイクロコンピュータ３１５へ信号を送信する。その信号をマイクロコンピュータ３１５が受信した後に、空調機の室外機［冷暖機種］３１１内に異常がないことをマイクロコンピュータ３１５が判断すると、圧縮機動作信号送受信手段３１６へ圧縮機動作信号を送信し、圧縮機動作信号送受信手段３１６が受信して、圧縮機３１７へ圧縮機動作信号を送り、圧縮機３１７が正常に圧縮機動作信号を受信すれば、圧縮機３１７が動作を行う。
【００３３】
また、マイクロコンピュータ３１５が圧縮機動作信号送受信手段３１６へ圧縮機動作信号を送るのと同時に信号解析手段３１４へ室外機動作中信号を送る。その信号を、信号解析手段３１４が解析して、正しい信号で有れば冷暖機種信号受信手段［シリアル信号］３１３へ信号を送る。その信号を冷暖機種信号受信手段［シリアル信号］３１３が受信し室接続線へ送信する。信号が接続線を通過して冷暖機種信号送受信手段［シリアル信号］３０９が受信し、信号解析手段３０８へ信号を送る。信号解析手段３０８が信号を解析してマイクロコンピュータ３０７に信号を送信しマイクロコンピュータ３０７が受信して、空調機の室外機［冷暖機種］３１１が正常に動作していることを判断する。
【００３４】
冷専機／冷暖機一体型空調機の室内機３０１と空調機の室外機［冷専機種］３１８を据え付けた場合には、ワイヤレスリモコン３０２から冷専機種信号と運転動作信号を送信すると、ワイヤレスリモコン信号受信手段３０３が冷専機種信号と運転動作信号を受信して、信号解析手段３０４に送信する。信号解析手段３０４が冷専機種信号と運転動作信号を受信して解析を行い、マイクロコンピュータ３０７へ冷専機種信号と運転動作信号を送信し、マイクロコンピュータ３０７が信号を受信した後に、冷専機／冷暖機一体型空調機の室内機３０１が冷専機種と判断するのと同時に冷専機／冷暖機一体型空調機の室内機３０１内に異常がないことをマイクロコンピュータ３０７が判断すると、ワイヤレスリモコン３０２から送られた信号と同じ動作を冷専機／冷暖機一体型空調機の室内機３０１が行う。
【００３５】
元電源投入後から、３分以上経過すれば、マイクロコンピュータ３０７が圧縮機動作信号を信号解析手段３０８に送信して、信号解析手段３０８が圧縮機動作信号を解析して正しい信号ならば冷専機種信号送信手段３１０へ送信する。その信号を冷専機種信号送信手段３１０が受信し、空調機の接続線に信号を送信し、信号が接続線を通過すると空調機の室外機［冷専機種］３１８の冷専機種信号受信手段及び信号解析手段３１９が信号を受信して解析して、正しい信号で有れば圧縮機動作信号送信手段３２０へ圧縮機動作信号を送り、圧縮機動作信号送信手段３２０が信号を受信して圧縮機３２１へ信号を送信し、圧縮機３２１が圧縮機動作信号を正しく受信すれば、圧縮機３２１が動作を行うことにより空調機が正常の運転を行う。

【００４１】
また、空調機の室外機［冷専機種］３１８を冷専機／冷暖機一体型空調機の室内機３０１に接続［据え付け］をして、ワイヤレスリモコン３０２から冷暖機種信号を送信してマイクロコンピュータ３０７が冷暖機種と判断した場合、空調機の室外機［冷専機］３１８にシリアル信号を送るが、シリアル通信が返却されてこないため、マイクロコンピュータ３０７が異常と判断して、冷専機／冷暖機一体型空調機の室内機３０１の表示モニタに異常表示を行うことによって間違え防止を行う。

[0017]
If more than 3 minutes have passed since the main power supply was turned on, the microcomputer 107 transmits a compressor operation signal to the signal analysis means 108, and if the signal analysis means 108 analyzes the compressor operation signal and is a correct signal, the cooling / heating model Signal transmission / reception means [serial signal] 109 sends a signal, cooling / heating model signal transmission / reception means [serial signal] 109 sends a compressor operation signal to the connection line, and the signal is an air conditioner outdoor unit [cooling / heating model] 111 cooling / heating model signal It is transmitted to receiving means [serial signal] 112. The cooling / heating model signal receiving means [serial signal] 112 receives the signal and transmits it to the signal analyzing means 114, and the signal analyzing means 114 receives and analyzes it, and transmits the signal to the microcomputer 115. After the microcomputer 115 receives the signal, if the microcomputer 115 determines that there is no abnormality in the outdoor unit [cooling / heating model] 111 of the air conditioner, it transmits a compressor operation signal to the compressor operation signal transmission / reception means 116. The compressor operation signal transmission / reception means 116 receives the signal and sends the compressor operation signal to the compressor 117.

The signal is received by the cooling / heating model signal receiving means [serial signal] 113 and transmitted to the connection line. The signal passes through the connection line and is received by the cool / warm model signal transmission / reception means [serial signal] 109 and sends the signal to the signal analysis means 108. The signal analysis means 108 analyzes the signal, transmits the signal to the microcomputer 107, and the microcomputer 107 receives it, and determines that the outdoor unit [cooling / heating model] 111 of the air conditioner is operating normally.
[0019]
When the outdoor unit [cooling type] 118 of the air conditioning unit / cooling / heating unit type air conditioner is installed in the indoor unit 101, the cooling type / cooling type switch 105 is cooled before turning on the main power. Set to exclusive model, and then turn on the main power.

[0021]
If more than 3 minutes have elapsed since the main power supply was turned on, the microcomputer 107 transmits a compressor operation signal to the signal analysis means 108. If the signal analysis means 108 analyzes the compressor operation signal and is correct, It transmits to the model signal transmission means 110. The cold special model signal transmission means 110 receives the signal and transmits the signal to the connection line of the air conditioner. When the signal passes through the connection line, the cold special model signal reception means and signal analysis of the outdoor unit [cool special model] 118 of the air conditioner The means 119 receives and analyzes the signal, and if it is the correct signal, sends the compressor operation signal to the compressor operation signal transmission means 120, and the compressor operation signal transmission means 120 receives the signal and sends it to the compressor 121. When the signal is transmitted and the compressor 121 correctly receives the compressor operation signal, the air conditioner performs normal operation by the operation of the compressor 121.
[0022]
When the outdoor unit [cooling type] 118 is installed (connected) to the indoor unit 101 of the air conditioner / cooling / heating unit type air conditioner, after the installation, the room of the cooling unit / cooling / heating unit type air conditioner When the original power supply is turned on by turning ON the cold special model / cool warm model switch 105 in the machine 101, the signal analysis means 104 recognizes the cold special model and transmits the cold special model signal to the microcomputer 107. The microcomputer 107 operates as a cold-only model.
[0023]
When an air conditioner operation signal [for example, cooling operation / set temperature 25 ° C./wind speed Hi: room temperature is 26 ° C. or higher] is transmitted from the wireless remote controller, the inside of the indoor unit 101 of the air conditioner / cooler / heater integrated air conditioner is transmitted. When the wireless remote control signal receiving means 103 receives the air conditioner operation signal, the wireless remote control signal receiving means 103 sends the air conditioner operation signal to the signal analysis means 104, and the signal analysis means 104 analyzes the air conditioner operation signal to obtain the correct signal. If it is, the air conditioner operation signal is sent to the microcomputer 107. If the microcomputer 107 receives the air conditioner operation signal and 3 minutes have passed since the power was turned on, and the fan motor or the like is operating normally, it sends a cold machine signal to the signal analysis means 108, When the analysis unit 108 receives the refrigeration equipment signal, the signal is sent to the refrigeration equipment signal transmission means 110, and the refrigeration equipment signal reception means and the signal analysis means 119 in the outdoor unit [cooling equipment model] 118 of the air conditioner. The cold special model signal is sent to the cold special model signal reception means and the signal analysis means signal analysis means 119 to receive and analyze the signal and send the compressor operation signal to the compressor operation signal transmission means 120. When the compressor operation signal transmission means 120 receives the signal and transmits the signal to the compressor 121, and the compressor 121 receives the signal, the compressor operates to become a cold-only model.
[0024]
When the outdoor unit [cooling / heating type] 111 is installed (connected) to the indoor unit of the cooling / cooling / heating integrated air conditioner, after the installation, the indoor unit 101 of the cooling / cooling / heating integrated air conditioner is installed. When the original power supply is turned on by turning off the internal cooling / cooling model switching switch 105, the signal analysis means 104 recognizes the cooling / heating model, and transmits the cooling / heating model signal to the microcomputer 107. 107 performs the operation of the cooling / heating model.
[0025]
When an air conditioner operation signal [for example, heating operation / set temperature 25 ° C./wind speed Hi: room temperature is 24 ° C. or lower] is transmitted from the wireless remote controller 102, the inside of the indoor unit 101 of the air conditioner / cooling / heating unit integrated air conditioner When the wireless remote control signal receiving means 103 receives the air conditioner operation signal, the wireless remote control signal receiving means 103 sends the air conditioner operation signal to the signal analysis means 104, and the signal analysis means 104 analyzes the air conditioner operation signal and corrects it. If it is a signal, an air conditioner operation signal is sent to the microcomputer 107. If the microcomputer 107 receives the air conditioner operation signal and more than 3 minutes have passed since the power was turned on, and the fan motor and the like are operating normally, a cooling / heating model signal is sent to the signal analysis means 108 for signal analysis. When the means 108 receives the cooling / heating model signal, it sends a serial signal to the cooling / heating model signal transmission / reception means 109 and sends the serial signal to the cooling / heating model signal receiving means [serial signal] 112 in the outdoor unit [cooling / heating model] 111 of the air conditioner. If the signal analysis means 114 receives the serial signal and is a normal signal, the serial signal is transmitted to the microcomputer 115. If the microcomputer 115 receives the serial signal and the conditions allow the air conditioner to operate correctly, the compressor operation signal transmission / reception means 116 transmits a compressor operation signal to the compressor operation signal transmission / reception means 116, and the compressor operation signal transmission / reception means 116 transmits the compressor 117. When the operation signal is transmitted to the compressor 117 and the signal is received by the compressor 117, the compressor 117 is operated, so that the model becomes a cooling / heating model.
[0026]
With the above, the cold-cooled model or the cool-warm model operates normally. However, the outdoor unit [cooling / heating model] 111 of the air conditioner is temporarily connected [installed] to the indoor unit 101 of the cooling-only / cooling / heating integrated air conditioner. When the original power supply is turned on by mistakenly turning on the cooling / cooling model switching switch 105, the signal analysis means 104 recognizes the cooling model, sends a cooling model signal to the microcomputer 107, Since the serial communication is not performed when the computer 107 determines that the model is the cold-only model, the microcomputer 115 determines that the abnormality is abnormal and the compressor 117 is not operated. Is not displayed on the display monitor of the indoor unit, but the compressor 117 does not operate and air conditioning is performed. Because it is not, abnormality can be determined).
[0027]
In addition, the outdoor unit [cooling special model] 118 of the air conditioner is connected [installed] to the indoor unit 101 of the cooling / cooling / heating integrated air conditioner, and the cold dedicated model / cooling / heating model switching switch 105 is mistakenly turned OFF. When the main power source is turned on, the signal analysis unit 104 recognizes the cooling / heating model, transmits a cooling / heating model signal to the microcomputer 107, and the microcomputer 107 determines that the cooling / heating model is selected. Special equipment] Sends a serial signal to 118, but since serial communication is not returned, the microcomputer 107 determines that there is an abnormality and displays an abnormality on the display monitor of the indoor unit 101 of the air conditioner integrated with the cooling / heating apparatus. To prevent mistakes.
[0028]
The above operation will be described with reference to the flowchart of FIG. First, at step 202, the outdoor unit of the air conditioner is connected [installed] to the indoor unit of the air conditioner / cooling / heating integrated air conditioner. In step 203, it is determined whether the outdoor unit is a cooling-only model. If it is a cooling-only model, in step 204, the cooling-only model / cooling / heating model switching switch of the indoor unit control device of the cooling-only / cooling / heating integrated air conditioner is determined. Turn it on. After that, by turning on the original power [turn on the rated voltage] in step 205, the air conditioner is changed to the cold-only model (step 206). After that, the air conditioner normal operation signal is sent from the remote control, and when the indoor unit controller of the air conditioner / cooling / heating integrated air conditioner correctly receives the remote control signal and 3 minutes have passed since the main power supply was turned on, The compressor in the outdoor unit (cold-only model) is operated, and the air conditioner operates normally (step 210).
[0029]
When the outdoor unit of the air conditioner is a cooling / heating model, it is determined whether the outdoor unit is a cooling / cooling model in Step 203, and “NO” is determined for the cooling / heating model. Turn off the cooling / cooling model switching switch of the indoor unit control device. Thereafter, the power source is turned on [rated voltage is turned on] in step 208, so that the air conditioner → cooling / heating model is obtained (step 209). After that, the air conditioner normal operation signal is sent from the remote control, and when the indoor unit controller of the air conditioner / cooling / heating integrated air conditioner correctly receives the remote control signal and 3 minutes have passed since the main power supply was turned on, The compressor in the outdoor unit (cold-only model) is operated, and the air conditioner operates normally (step 210).
[0030]
As described above, according to this embodiment, since the indoor unit (including the control device) of the air conditioner of the cooling-only model and the cooling / heating model is integrated, the manufacturer can achieve common use, and thus mass production is performed. This leads to cost reduction. In addition, since the service parts can be unified, the management form can be simplified, and the installation contractor does not mistake the set of the outdoor unit and the indoor unit, so that the management can be simplified. It is done.
