The major HCFC refrigerant currently used in centrifugal central air conditioner is HCFC-123, which has much lower ODP (0.012), ODP (0.012) and shorter lifetime of staying in atmosphere than those of HCFC-22, thus it is suggested to postpone the stop of HCFC-123 use for five more years. As for that fact that HCFC has a extraordinary high ratio of use on repair and maintenance purposes in Taiwan, this situation can been greatly improved due to the use of non HCFC refrigerant by newly installed equipments since 2010. EPA Taiwan needs to simultaneously review the allocation system of HCFC refrigerant on repair and maintenance uses With regard to the air condition of vehicle use, the new and large passenger bus currently use HCFC-22 refrigerant. It is suggested that these new buses and other new air conditioner together stop using HCFC-22 in new equipment since 2010. It is also suggested that old and small cars that use CFC-12 fully stop using CFCs refrigerants since 2010. This rule is suggested to put into one of the checking items of vehicle testing and management As for the build-up of the halon management center, this project has completed assisting: national defense units on halon movement, Taipei Rapid Transit Corporation and public agencies on halon testing for the improvement of halon exchange and reuse. These works has not only provided the halon regent demand sites where halon uses are necessary, but also directly reduced the improper use and emission of halon regent. The continuous operation of the halon management center are important and necessary.
