Refrigerant reclamation is the act of processing used refrigerant gas which has previously been used in some type of cooling loop such that it meets specifications for new refrigerant gas. In the United States, the Clean Air Act of 1990 requires that used refrigerant be processed by a certified reclaimer, which must be licensed by the United States Environmental Protection Agency (EPA), and the material must be recovered and delivered to the reclaimer by EPA-certified technicians.〔(Secion 608 of the Clean Air Act of 1990 )〕 ==Background== Coolant and refrigerants are found throughout the industrialized world, in homes, offices, and factories, in devices such as refrigerators, air conditioners, central air conditioning systems (HVAC), freezers, and dehumidifiers. When these units are serviced, there is a risk that refrigerant gas will be vented into the atmosphere, hence the creation of technician training and certification programs in order to ensure that the material is conserved and managed safely. Mistreatment of these gases has been shown to deplete the ozone layer and is suspected to contribute to global warming.〔(Emissions of Greenhouse Gases Report by the US Department of Energy )〕 Reclamation of used refrigerant by an EPA-certified reclaimer is required in order to sell used refrigerant not originating from and intended for use with motor vehicle air conditioners and stationary equipment like air conditioners, refrigerators, central air conditioning systems (HVAC), and other cooling equipment. The EPA implemented a Code of Federal Regulations in 1995〔(Code of Federal Regulations: Protection of Stratospheric Ozone )〕 in order to develop actions to meet the agreements defined in the Montreal Protocol. Reclamation, as it refers to refrigerants, is one of three components in a refrigerant management process. The EPA defines refrigerant reclamation as "Reclaim refrigerant means to reprocess refrigerant to at least the purity specified in appendix A to 40 CFR part 82, subpart F (based on AHRI Standard 700–1993, Specifications for Fluorocarbon and Other Refrigerants) and to verify this purity using the analytical methodology prescribed in appendix A. In general, reclamation involves the use of processes or procedures available only at a reprocessing or manufacturing facility."〔(Protection of Stratospheric Ozone: Supplemental Rule Regarding a Recycling Standard Under Section 608 (Proposed) of the Clean Air Act )〕 EPA establishes rules and regulations that reclaimers must acknowledge, and they license these reclaimers to operate. In most cases wholesale distributors provide this service as an intermediary, since they have such great resources to manage distribution. The EPA requires that refrigerant be reclaimed when a certified technician recovers refrigerant and puts it in a special DOT container and has no intention of putting it back in the same system from which it was recovered. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Refrigerant reclamation」の詳細全文を読む スポンサード リンク
