555843 經濟部智慧財產局員工消費合作社印奴 A7 B7 五、發明説明(1 ) 本發明之標的是一種包括五氟乙烷,1,1,1,2 -四氟乙烷,及二甲醚之組成物,它在冷凍及/或空氣調 節中之用途及含彼之熱傳系統。 熱傳系統包括例如冰箱,熱泵及空氣調節系統。 在此種裝置中,合適沸點之冷凍劑在低壓下蒸發,自 第一周圍媒介(或區)帶走熱。因此所形成之蒸汽而後使 用一壓縮機來壓縮,而後通入冷凝機中,其中它轉變成液 態,使熱釋入第二周圍區。由此冷凝之液體而後流入減低 機中,在其出口,轉變成液汽雙相混合物,此混合物最終 導入蒸發器中,其中液體再次在低壓下蒸發而完成此循環 〇 用來壓縮蒸汽且循環流體所需之機械能藉馬達或藉內 燃引擎來提供。正如在任何機械裝置中者,移動的部分需 要被合適地潤滑。所用之潤滑劑形成熱傳系統的整合部份 且經由長期保持合適的潤滑而管理其效能及其壽命。 特別地,在每一次通過壓縮機時,冷凍劑會與在其移 動部分上所存在之潤滑劑接觸而易於帶出一些潤滑劑,此 潤滑劑在其循環中伴者冷凍劑且因此會在蒸發器中被發現 。現在,後者通常會變成低溫,在此點上,潤滑劑的粘度 特別高,此意味此潤滑劑有累積在蒸發器中且因此不能再 返回壓縮器的危險,此種返回在本文中稱爲'^油之返回〃 〇 因此,若此種油之返回不足,在壓縮機之移動部分上 所存之潤滑劑的量無法隨著時間保持恆定,因此,衝擊該 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) I------裝---J--J_ 訂----- ----.
