This is taken from pressure temperature comparison table.Thank you for asking about your Volkswagen. On a 95 degree day, the low side should be reading at or around 35 PSI, so it sounds like the A/C is in normal working condition. Try checking the high-side PSI to see if it is abnormal. The high-side PSI reading on a 95 degree day should be about 240 PSI. Thank you!-BDPR410A is a 50:50 mixture by weight of R32 and R125. Temperature glide is very small (less than 0.17K).

It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil.That’s with a Fahrenheit of 70–74 degrees Fahrenheit as the ambient temperature. Low and high side pressures should increase as the ambient temperature rises. The high-side pressure on a fully operating system will be around twice the ambient temperature + 50 PSI.

Locate the critical point: The critical point represents the highest temperature and pressure at which the refrigerant can exist as a liquid and vapor simultaneously.pressure side, etc.). It is also recommended to have spare seals for other components available during restart of the system. The same type of seal can be used; it should just be a new one that has not previously been in R-22 service. A rigorous leak check regime pre- and post-retrofit will minimize any refrigerant losses. Obviously, any seals ...If you’re a fan of reality television, chances are you’ve heard of the hit show “90 Day Fiancé”.
