Abstract
【解決手段】本発明の給湯システムは、貯湯タンク5と、ヒートポンプ式加熱手段2と、補助加熱手段6とを備え、ヒートポンプ単独運転と、ヒートポンプ式加熱手段2および補助加熱手段6を同時に運転する補助加熱運転とが可能であって、外気温度が同一である場合において、補助加熱運転時のヒートポンプ式加熱手段2の圧縮機周波数が、ヒートポンプ単独運転時のヒートポンプ式加熱手段2の圧縮機周波数より大きく、かつ、補助加熱運転時のヒートポンプ式加熱手段2のヒートポンプ効率が、ヒートポンプ単独運転時のヒートポンプ式加熱手段2のヒートポンプ効率より低い。

Description
前記貯湯タンクに対して温水を供給可能なヒートポンプ式加熱手段と、
前記貯湯タンクから給湯端末に供給される温水を加熱可能な補助加熱手段とを備え、
前記ヒートポンプ式加熱手段を単独で運転するヒートポンプ単独運転と、
前記ヒートポンプ式加熱手段および前記補助加熱手段を同時に運転する補助加熱運転とが可能であって、
外気温度が同一である場合において、前記補助加熱運転時の前記ヒートポンプ式加熱手段の圧縮機周波数が、前記ヒートポンプ単独運転時の前記ヒートポンプ式加熱手段の圧縮機周波数より大きく、かつ、前記補助加熱運転時の前記ヒートポンプ式加熱手段のヒートポンプ効率が、前記ヒートポンプ単独運転時の前記ヒートポンプ式加熱手段のヒートポンプ効率より低いことを特徴とする。
そのときの外気温度においてCOPが最大となる加熱能力より大きく、且つ、前記ヒートポンプ式加熱手段の1次エネルギー効率が、前記補助加熱手段の1次エネルギー効率以上となるように導出されることを特徴とする。
本実施形態の給湯システムでは、湯切れ時にヒートポンプ部2およびガス給湯器6を同時に運転して沸き上げ運転が行われる場合に、ヒートポンプ部2のヒートポンプ効率を下げ、圧縮機周波数を上げて運転するので、ヒートポンプ部2としての加熱能力は増加する。このため給湯システム全体の中のヒートポンプ部2の加熱比率が増加することになり、ヒートポンプ部2およびガス給湯器6を含めた給湯システム1の総合的なエネルギー効率を最適にできる。

6 ガス給湯器(補助加熱手段)
