5、D Because of environmental concerns, SAE J2788 recovery/recycle standard established more stringent equipment performance features and requirements for on-site recovery, recycle and recharge of HFC-134a (R-134a) in mobile air-conditioning (A/C) systems. This standard is for HFC-134a (R-134a) recover

SCOPE The p
7、urpose of this SAE Standard is to provide minimum performance and operating feature requirements for the recovery of HFC-134a (R-134a) refrigerant to be returned to a refrigerant reclamation facility that will process it to the appropriate ARI 700 Standard or allow for recycling of the recovered ref

It is not acceptable that the refrigerant removed from a mobile air-conditioning (A/C) system with this equipment be directly returned to a mobile A/C system. This information applies to equipment used to service automobile
9、s, light trucks, and other vehicles with similar HFC-134a (R-134a) A/C systems. 1.1 Improved refrigerant recovery equipment is required to ensure adequate refrigerant recovery to reduce emissions and provide for accurate recharging of mobile air conditioning systems.
