Compact, High EfficientIndustrial Oil-Free Design

空調系統最佳化設計ASHRAE有關冷凍空調系統使用油分離器的分析報告Vol.16, No.3 December 1999

劉中哲摘譯(ASHRAE outlines oil separator efficiency；p. 22)

ASHRAE研究計畫RP469，針對150與300 SUS兩種冷凍油，於蒸發器與冷凝器中之平滑管與微鰭管的熱傳分析，已得到一些結論。在蒸發器的部分，研究結果顯示，無論平滑管或微鰭管，冷凍油並不會降低其熱傳特性，因此計算蒸發器尺寸時，直接使用冷媒的特性即可。冷凍油對冷凝器的影響則大不相同，當油濃度5 %時，兩種冷凍油以及兩種熱傳管的熱傳特性皆會降低10 % ~ 20 %，油濃度1 %時，熱傳特性亦會降低5 % ~ 10 %。為了克服熱傳的降低，選擇冷凝器時要特別注意。
