The correct answer is D. Recover more refrigerant in an A/C system.
Recovery/recycling/recharging equipment certified to SAE J2788 is designed to improve refrigerant handling efficiency and effectiveness in automotive air conditioning (A/C) systems. It specifies the requirements and performance criteria for equipment used to recover, recycle, and recharge refrigerants in A/C systems.
SAE J2788 equipment is certified to recover a large portion of the refrigerant from the A/C system. This helps reduce the release of harmful refrigerant gases into the atmosphere and promotes environmental sustainability. By recovering more of the refrigerant, the equipment enables proper disposal or recycling of the refrigerant, preventing its release and minimizing environmental impact.
While increased charging accuracy and post-2008 manufacturing may also be associated with equipment certified to SAE J2788, the key purpose is to recover more refrigerant in an A/C system. Therefore, option D, "Recover more refrigerant in an A/C system," is the most accurate answer.
