註：１.冷凍特性試驗係依據吸入冷媒蒸氣過熱１０℃,冷媒液體超冷５℃.
※正常運轉時請調整冷媒蒸氣過熱溫度約５℃比較適合.
２.使用於蒸發溫度－１５℃以下時,高壓部將產生超高溫會影響冷凍油使之稀薄,需要增加裝置油冷卻器.
(Economizer Cooler)
３.可容許檢驗值±５％.
NOTE:1.The Refrigerating Performance Based on 10℃ Suction Superheat , 5℃ Liquid Subcooling.
2.The Suction Temp. below - 15℃ is in need of oil cooler (Economizer cooler).
3.Permissible Inspection Value±5%.
