我國內廢家電冷媒回收處理業者所收集之廢家電所充填冷媒多為CFCs型冷媒,若於回收、清除及處理過程未妥善處理而造成冷媒溢散於周遭環境,將導致大氣環境-臭氧層之消耗,最終危害人類;為妥善處理與管理廢家電付給冷媒與環保冷媒,本研究擬對國內13廠冷媒回收處理業者進行實地訪查,針對各廠冷媒回收設備使用情形及冷媒回收量進行瞭解,並將所收集之數據進行回收率推估,以評估我國廢家電冷媒回收情形;並將回收率與回收設備使用情形進行線性回歸分析,以瞭解兩者間之相關性。 回收率推估後之結果顯示,我國電冰箱及冷氣機壓縮機冷媒、電冰箱發泡冷媒之回收率平均值分別為36.6%、28.3%及51.9%,並將此與日本冷媒回收率成效進行分析,結果顯示,我國冷媒回收率雖高於法規所規範之數值,但均遠低於日本冷媒回收率;另線性迴歸分析結果顯示,壓縮機冷媒回收與設備操作人員之操作方式有著密切之相關性,而發泡冷媒與電冰箱破碎設備之密閉性有著密切之相關性,故本研究規劃改善上述項目之方法,期能提升我國廢家電冷媒回收率。
The refillable refrigerants processed by appliance refrigerant recovery industry inbound Taiwan are almost CFCs types which could possibly be spilled out to the surroundings if the recovery and recycle of them did not properly performed and result in consumption of ozone layer in atmosphere and also be harmful for human being eventually. Nonetheless, the quantity of HC-type environmental refrigerants are increasing year by year due to its application on so many appliances recently, and this kind of refrigerant possesses pyrophoric property which could lead to industrial security accidents if its recycle or recovery procedure is not performed appropriately. Thus, this study aimed at implementation of assessment about recovery rate through field investigation against 13 refrigerant recovery factories in domestic arena, with comprehension of their refrigerants recovery quantity and usage status of their recovery equipment, according to the collected data, we could carry out assessment on recovery status of wasted appliances inside the country, thus, it could be compared with usage status of recovery equipment by linear regression analysis to understand correlation between each other. The evaluation results showed that the recovery average of refrigerant from freezers, air conditioners and foamed refrigerant of freezers are 36.6%, 28.3% and 51.9% respectively. Although the recovery rate inside the country is higher than the specific values in legal regulations, however, it is still lower than those in Japan. On the other hand, the results from linear regression analysis showed that there is close correlation between refrigerant recovery and the operators’ manipulation and complete recovery of refrigerator oil as well. And there is also tight connection between foamed refrigerants and impermeability of grinders for freezers, therefore, this study aims at improvement of the methods above and hope to improve the recovery rate of wasted appliance refrigerants inside our country.
