Question

Technician A says that recovery/ recycling/ recharging equipment for R-1234yf refrigerant requires integration with a refrigerant identifier. Technician B says that recovery/ recycling/ recharging equipment for R-1234yf refrigerant uses a 17.0 mm O.D. quick coupler on the low-side service hose. Who is right?

Answer 1

Both Technician A and Technician B are correct. Technician A mentions the necessity of a refrigerant identifier for R-1234yf equipment, while Technician B notes the specific size of the quick coupler for the low-side service hose used in these systems.

Step-by-step explanation:

Both Technician A and Technician B are correct in their statements about recovery/recycling/recharging equipment for R-1234yf refrigerant. Technician A is correct in saying that equipment for R-1234yf refrigerant requires integration with a refrigerant identifier. This ensures that the correct type of refrigerant is being recovered and recycled, preventing contamination and maintaining system integrity. Technician B is correct in stating that the equipment uses a 17.0 mm O.D. quick coupler on the low-side service hose, which is a standardized fitting size for R-1234yf systems to facilitate proper connection and prevent accidental cross-contamination with other refrigerant types.
