:Information on refrigerant production and use patterns in air-conditioning and refrigeration sectors was assembled through system manufacturers, and a much up-to-date outline in distribution of these types of refrigerants could be estimated and drawn. Mechanisms and guidelines that could much effectively manage the uses were proposed, to promote the rationale use of halogenated carbon refrigerants and to minimize the unwanted leakage of substances. A management strategy that is more conforming to the international control regime were proposed to the Environmental Protection Administration, further descriptions and details could reference to chapter 4.1.4. Survey findings show trends in use of 3 main types of refrigerant in the past 3 years, HCFCs remained stablised, CFCs decrease year after year, and such decrease was almost replaced by the use of HFCs. Majority of HFCs was used in motor vehicle air-conditioner, and the demand for HFC-134a in servicing increased gradually in the recent years. Considering the effects in greenhouse gas reduction is less significant, but the impacts to economy could be much bigger, restricting the use of HFCs in transportation sector is placed as the much long term option. The project has completed the framework of halon banking management in the previous year, and this year project focused on the detail rules and procedure for dissembled halon, which is based on the amended regulation of ozone depleting substances management. More than 10 testing have been conducted on the development of halon recovery systems and around 800 testing samples of recovered halon and alternatives were collected, the result will be used as required parameters for future operation. A visit to the Australia national halon bank was also arranged this year in order to establish a channel of cooperation on treatment of contaminated halon stocks. A two days forum on atmospheric protection was held in 2005, and an exhibition on the achievements for the past years efforts was displayed to general public parallel with the forum, which including ODS consumption reduction, illegal trade prevention, domestic alternative technology development, industrial voluntary action programme.
