以下、図1を用いて、本発明の第1実施形態を説明する。本実施形態の暖房システム1は、住宅用家屋に適用されており、リビング、キッチン、寝室等の各室内(暖房対象空間)の暖房を行うものである。さらに、この住宅用家屋は、いわゆる高気密住宅と呼ばれる気密性の高い家屋であって、定常的な換気が必要とされる。
本実施形態では、第1実施形態に対して、図2の模式的な全体構成図に示すように、低温側ヒータコア36の構成等を変更した例を説明する。
本実施形態では、第1実施形態に対して、図3の模式的な全体構成図に示すように、第2水循環回路37に太陽熱パネル40を追加した例を説明する。
本実施形態では、第1実施形態に対して、図4の模式的な全体構成図に示すように、第1水循環回路21と第2水循環回路37とを接続した例を説明する。従って、本実施形態の第2水循環回路37では、第1水循環回路21と同じ給湯水が循環する。
本実施形態では、第1実施形態に対して、図5の模式的な全体構成図に示すように、第2水循環回路37に加熱器41を配置した例を説明する。具体的には、この加熱器41は、高温側ヒータコア35から流出した温水を熱源として加熱対象物を加熱し、この加熱対象物を加熱することによって温度低下した温水を低温側ヒータコア36の温水入口側へ流出させるものである。
本実施形態では、第1実施形態に対して、図6に示すように、熱媒体循環回路50を追加した例を説明する。この熱媒体循環回路50は、第2温水(例えば、エチレングリコール水溶液)を循環させるものである。さらに、熱媒体循環回路50には、第3水循環ポンプ51、水−冷媒熱交換器12の水通路12bおよび水−水熱交換器52の第1水通路52aが配置されている。
