Socalled "new sources" means replacing the old A / C system with one using a new refrigerant. The energy resources laboratory at ITRI has already developed replacement technology that costs only NT $ 4,000-5,000 to manufacture, and even if with labor figured in auto body shops are asking for US $ 10,000, most car owners should be able to cope with that.
所謂「開源」，是指將舊車冷氣改裝為新冷媒系統，目前工研院能資所已研發出一種成本只要四、五千元台幣的換裝技術，即使加上人工成本，坊間維修廠開價要上萬元，一般車主也應該可以負擔得起。
