Zusammenfassung: | PROBLEM TO BE SOLVED: To resolve a problem in which a filter does not include simultaneously a superior acoustic performance and a thermodynamic performance.SOLUTION: An acoustic filter comprises an inlet duct 2, an outlet duct 3 and at least one main chamber 4A. The inlet duct 2 includes a refrigerant fluid inlet 5 and a refrigerant fluid delivering end part 6. The refrigerant fluid delivering end part 6 is oppositely faced against the refrigerant fluid inlet 5 guiding the refrigerant fluid to the main chamber 4A. The outlet duct 3 comprises a refrigerant fluid outlet 7 and a refrigerant fluid collection end part 8. The refrigerant fluid collection end part 8 is oppositely faced against the refrigerant fluid outlet 7 to enable the refrigerant fluid to be guided from the main chamber 4A to the refrigerant fluid outlet 7. The filter is provided with a resonance chamber 9 placed adjacent to the inlet duct 2 and adjacent to the main chamber 4A. The resonance chamber 9 and the inlet duct 2 are communicated in fluid by at least one resonance chamber 10A and the resonance chamber 9 is separated from the main chamber 4A by a sealing wall 11.SELECTED DRAWING: Figure 1
【課題】フィルタが良好な音響および熱力学的性能を同時に含まないという問題を解決する。【解決手段】音響フィルタが、入口ダクト2と、出口ダクト3と、少なくとも1つの主チャンバ4Aとを備え、入口ダクト2が、冷媒流体入口5と、冷媒流体送出端部6とを含み、冷媒流体送出端部6が前記冷媒流体入口5に対向しており、冷媒流体を主チャンバ4Aに誘導することができ、出口ダクト3が、冷媒流体出口7と、冷媒流体収集端部8とを備え、冷媒流体収集端部8が、前記冷媒流体出口7に対向しており、冷媒流体を主チャンバ4Aから前記流体出口7に誘導することができる。フィルタが、入口ダクト2に隣接し、かつ主チャンバ4Aに隣接して配置された共鳴チャンバ9を備え、共鳴チャンバ9および入口ダクト2が、少なくとも1つの共鳴管10Aによって流体連通され、共鳴チャンバ9が、封止壁11によって主チャンバ4Aから分離されている。【選択図】図1 |
