Final answer:
The requirements for recovery/recycling/recharging equipment for R-1234yf refrigerant are set by SAE, EPA, ASHRAE, and ANSI.
Step-by-step explanation:
The requirements for recovery/recycling/recharging equipment for R-1234yf refrigerant are set by multiple organizations. The Society of Automotive Engineers (SAE) has set standards for the equipment used in auto air conditioning systems that use R-1234yf refrigerant. The Environmental Protection Agency (EPA) has regulations in place to ensure the proper handling and recovery of refrigerants, including R-1234yf. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) provides guidelines for the safe handling and disposal of refrigerants. On the other hand, the American National Standards Institute (ANSI) sets standards for the design and performance of equipment used in the HVAC industry.
