Description
図1は、本発明の実施の形態1のヒートポンプ暖房システムを示す構成図である。図1に示すように、本実施の形態1のヒートポンプ暖房システム1は、ヒートポンプ熱源機2及びタンクユニット3を備える。ヒートポンプ熱源機2は、暖房機器4による暖房に使う熱媒体となる液体を加熱する。この液体として、例えば、水、不凍液、またはブラインなどを使用できる。暖房機器4は、ヒートポンプ熱源機2から供給される液体の熱で、室内を暖房する。図1では、二つの暖房機器4が並列に接続されているが、暖房機器4の個数は1個でも3個以上でも良い。
次に、図5を参照して、本発明の実施の形態2について説明するが、上述した実施の形態1との相違点を中心に説明し、同一部分または相当部分は同一符号を付し説明を省略する。図5は、本実施の形態2における往き温度の目標値と液体温度差ΔTaの目標値との関係を示す図である。本実施の形態2において、制御装置20は、暖房運転のとき、図3に示す関係に代えて、図5に示す関係に基づき、液体温度差ΔTaの目標値を設定する。
