SAE’s new J2843 R-1234yf recovery/recycling equipment for refrigerants for mobile air-conditioning and J2851 R-1234yf refrigerant recovery equipment for mobile automotive air-conditioning systems are expected to meet industry refrigerant containment of emissions criteria in recovering R-134a.
SAE International’s Interior Climate Control Standards Committee has developed requirements for the new R-1234yf refrigerant to be used in future MAC systems and that the new R-1234yf SAE standards and recommended practices are expected to be published in 2011.
Prior to this, SAE introduced the updated 2788 HFC-134a (R-134a) Recovery/Recycling Equipment and Recovery/Recycling/Recharging for Mobile Air-Conditioning Systems, which superseded the current industry requirements to reduce refrigerant emissions during servicing.
SAE International’s J1770 automotive refrigerant recovery/recycling equipment for use with both R-12 and R-134a, issued in October, 1995, also failed to meet the current standard of refrigerant recovery from the MAC system and did not assure the accurate recharge of the system with refrigerant.
