根據計算結果，並充分考慮到小體積、小功率的應用環境限制，進一步完成了整個製冷系統的設計實現，包括壓縮機的選型和設計、換熱器的選擇和計算以及節流管的計算等等。其中，滾動轉子壓縮機的結構微型化設計是整個製冷系統設計的核心部分。 -
Abstract : on the basis of the analysis about noise sources of the air compressor, it shows that air dynamic noise is primary one. according to the theory of fluid mechanics, the mathematics model of the air compreesor air dynamic noise is found, which shows the relationship between the sound power level and other parameters. the knowing noise of the air compressor " s air dynamic is of low frequencies. the reliable data is provided for the noise and vibration control
文摘:通過對空壓機噪聲源的分析，確認空壓機噪聲源中的空氣動力性噪聲為最強；由流體流場的聲學理論，建立空壓機動力性噪聲源的力學模型，它表明聲功率與其它參數的關系；並知空壓機的空氣動力性噪聲呈低頻特性，這為噪聲及振動控制提供了可靠的依據 -
