1225515 五、發明說明（〇 " ^ ' 麵~' '~， 本發明系關於一種潤滑組合物及其在冷凍系統中的用 途。 幕所皆知，冷凍系統中的過度發泡是一種不良現象。它 會使潤滑組合物在冷卻馬達線圈上、以及對壓縮機除熱上 的效能降低。太多的泡沫也會使過多的潤滑組合物流經系 統中的泵而進入冷凍系統的低壓側。但是適量的泡沫也是 有益處的’特別是它可以壓制由冷凍系統中的壓縮機所$ 造的噪音。1 9 98年ASHRAE冷凍技術手冊第7· 20節中曾說衣 明’ ”潤滑面頂端的泡沫層可減弱由壓縮機運轉部分所製 造的嚼音”。_泡沫的產生還有其他好處；舉例言之， 鲁 WO/9512649中揭示其可控制蒸氣的釋放速率，us 4829786 中則揭示其可促進濃縮油的回流。 傳統上’會在氟氣碳化物（CFC)和氫化氟氯碳化物 (HCFC)冷康氣體之潤滑組合物中使用礦油（mineral oil)。這些潤滑組合物/CFC/HCFC之混合物會呈現一種發 /包趨勢。在某些不宜或過度發泡的情況中，可發現對泡床 生成的控制係為必要。而在其他以產生泡沫為佳的例子 中丄則發現須促使泡沫生成。舉例言之，US 3，7 9 2，7 5 5中 揭不一種可減弱由運作中的密閉壓縮裝置所製造之噪音的 _ ^法’該法包括在運作期間攪拌一種含有有機矽氧烷發泡 劑之潤滑組合物。該發泡劑有助於產生並持續含有細微泡 /包顆粒的泡沫或泡沫堆，它們的功用則在於吸收並因而減 弱於運作期間由壓縮裝置所製造之噪音。US 3，7 9 2，7 5 5中 所揭不之CFCs包括三氣乙烯、二氯二氟甲烷（R_12)和一氯
