This paper addresses the fugitive emission factors of showcase at use-phase and disposal-phase. The residual quantities of Korean-made fifty- two waste showcase were weighed, using a commercial recover of refrigerants to determine the emission factors at the disposal-phase. On the other hand, the emission factors at use-phase were estimated from the residual quantities and operating times. The average residual rate of fifty two scarp showcase is determined to be 75.6 ± 5.3%. The emission factor at the use-phase is estimated to be 2.8 ± 0.7%/yr in the case of using average age of 11.1 years and the average residual rate determined here. The emission factor at the disposal-phase, refrigerant is accomplished has not recycled, the residual rate was assumed that the emission factor. We estimate 7.8 g/yr for the average emission quantity of refrigerant per operating showcase, while 234.4 g for that per waste showcase. Since the chemical compositions of refrigerant of waste showcase were the same as those of new refrigerant, it is expected that the refrigerant recovered from waste showcase can be reused for refrigerant.
