More on Making R1234yf in the USA >>. Its autoignition temperature is 405 degrees C, which means it’s harder to burn than paper. In fact, the only way HoneyWell/DuPont could get it to burn was to mix it with compressor oil and pass it over plate hotter than 900 degrees C. That’s hotter than most really hot exhausts.
At atmospheric pressure, the R134a has a boiling point of -26.8 o C and at 10psi pressure, its boiling point rises to -10.6 o C. If R134a is released into a room at atmospheric pressure and room temperature, it would instantly turn into gas. The temperature and pressure of the refrigerant have a direct relationship.Most automotive refrigerant is today is R134A. Newer vehicles may use R1234YF and this will become more common in the future. Diagnosis of R1234YF systems is different and not covered in this article.
