Five Questions to Compare if we can replace R134a by R1234yf refrigerant gas
Question 1: Can R-134a be used in an R-1234yf system?
No. While R-1234yf and R-134a have similar chemical and physical properties, system components (such as seals, compressors, and condensers) are designed specifically for their respective refrigerants. Using incompatible refrigerants may pose a safety hazard or damage the system. Furthermore, changing refrigerants on your own may void the manufacturer's warranty on your vehicle or equipment and may violate regulatory requirements.
No. R-1234yf utilizes unique left-hand threaded connectors on hoses, couplers, adapters, and other connections. This design prevents refrigerant mixing and protects system components.
After adding an internal heat exchanger to the system and optimizing operating conditions, the refrigeration performance of R-1234yf is close to that of R-134a.
Mixing R-134a with an R-1234yf system may reduce refrigeration efficiency and may damage the compressor. To ensure long-term stable operation of the system, use the refrigerant recommended by the vehicle manufacturer.
