If you’ve recently googled “it’s almost 2020 and I still have R22” then hopefully this article grants you some timely insights. The world of refrigerants has become much more complex since
This paper investigates the performance changes due to drop-in replacement of R22 to R32 in a residential air conditioner. The liquid density ratio between R32 and R22 at 0°C is 0.82.The R32 refrigerant gas is the best replacement for the R410A refrigerant. As it has the lowest global warming potential than R22, R11, R12, or R23, so R32 can R32 refrigerant is a relatively new innovation in AC technology developed as an alternative to the refrigerants used today. It is a hydrofluorocarbon, or HFC, air conditioning manufacturers are adopting as a safe, efficient, and environmentally friendly refrigerant option. Today’s most common AC refrigerants are R22 (also called Freon) and R410A. The answer: No.Putting R-410A refrigerant into an AC unit that was designed to use R-22 will cause the unit to die soon after it tries to run. Can I replace R22 with R134a?
Up to 10% lower capacity. Lubricant Recommendation: Compatible with mineral and alkylbenzene oil and if oil return becomes a concern, addition of polyolester lubricant in 5% increments could help resolve the issue.
