Claims (3)
- 特に冷媒としてCO2を利用する自動車用HVACの冷媒回路システムであって、
前記冷媒が、
冷媒ライン(23)に沿ってコンプレッサ(22)及びガス冷却器(24)を通って流れ、
内部熱交換器(26)及びアキュムレータ(28)を1つの構成要素に組み合わせた組み合わせ構成要素の高圧入口(25)に入り、
これにより高圧側の前記内部熱交換器(26)を通過した冷媒は、低圧側で前記アキュムレータ(28)内に中間的に蓄えられて該アキュムレータから取り出された冷媒と熱接触し、
これにより前記前記内部熱交換器(26)を通過した後、
前記組み合わせ構成要素(27)の高圧出口(32、33)に位置する前記冷媒ライン(23)が、互いに並行に切り替えられる前記冷媒ライン(23)の2つの別々の分岐部(34、35)に分割され、
各分岐部が膨張部材(36、37)と該膨張部材(36、37)の下流側にある蒸発器(38、39)とを有し、
これにより互いに並行に切り替えられる前記冷媒ライン(23)の分岐部(34、35)は共に、前記蒸発器(38、39)から前記組み合わせ構成要素(27)の低圧入口(40、41)を通って前記アキュムレータ(28)に続き、
その結果、前記中間的に蓄えられた冷媒は、前記冷媒ライン(23)に沿って前記組み合わせ構成要素(27)の低圧出口(42)を通って前記コンプレッサ(22)に再び達することができる、
前記内部熱交換器(26)及び前記アキュムレータ(28)を備えた前記組み合わせ構成要素(27)と、
互いに並行に切り替えられる前記2つの分岐部(34、35)に前記組み合わせ構成要素(27)に接続するためにマニホルド(29)が配置され、
前記マニホルド(29)が、前記冷媒ライン(23)の第1の分岐部(34)において前記第1の膨張部材(36)及び前記第1の蒸発器(38)に接続するための接続部を有する第1の二重接続要素(30)を備え、
前記マニホルド(29)が、前記冷媒ライン(23)の第2の分岐部(35)において前記第2の膨張部材(37)及び前記第2の蒸発器(39)に接続するための接続部を有する第2の二重接続要素(31)を備え、
前記第1及び第2の二重接続要素(30、31)の各々が、締結用に1つのネジを必要とする、
ことを特徴とする冷媒回路システム(1)。 - 前記第1の二重接続要素(30)が、前記第2の二重接続要素(31)と平行に対向して配置されている、
請求項1に記載の冷媒回路システム(1)。 - 前記第1の二重接続要素(30)及び前記第2の二重接続要素(31)が、互いの上に平行に配置されている、
請求項1に記載の冷媒回路システム(1)。
