Are there any refrigerants compatible with HVAC systems that use R-22 Freon?

Answer 1

*Puron, the chlorine-free replacement refrigerant for R-22.
*[If you are thinking about replacing your air conditioner or heat pump, keep in mind that Puron-based products offer several homeowner benefits, including:
*Energy Efficiency -
Most of our Puron air conditioners and heat pumps offer higher efficiency ratings. Keep in mind that the ratings don't change simply because they are Puron-based products - a 12 SEER rated air conditioner will deliver 12 SEER no matter what's in it. However, Puron's heat transfer properties lend themselves to higher efficiency performance.
*Future cost of service savings -
Because of U.S. government restrictions on future production refrigerants with ozone-harming CFC's, the refrigerant used ion most of today's heat pumps and air conditioners will become harder to find and eventually more expensive. Switching to Puron now can help you avoid the potential rising cost of servicing most of today's air conditioners and heat pumps.
*Reliability -
Carrier's air conditioners and heat pumps with Puron refrigerant have become the most reliable products in our entire line.
*Quiet Operation - Many of the air conditioners and heat pumps with Puron refrigerant also offer Carrier's Silencer System for quieter operation. ]

*In new air-conditioning and heat pump equipment for residential applications, Honeywell’s R-410A provides an optimal, long-term replacement for R-22. When designed and optimized for this refrigerant, a system can deliver a 5% gain in efficiency and, generally, a 10% increase in capacity compared to other R-22 alternatives. Additionally, as a higher pressure refrigerant, R-410A enables the design of more compact equipment thereby giving greater installation flexibility.

A further alternative is provided by R-407C. A blend of R-32, R-125 and R-134a, R-407C can be used for new equipment as well as retrofit existing R-22 systems. Relative to R-22 there is little to no capacity decrease with R-407C, however some loss of efficiency will occur. In designing for new equipment, some design changes may be required if retention of efficiency ratings are required. Additionally, in some systems, changes to heat exchangers may be required due to the increased temperature glide of the blend.

Answer 2

I really not sure. I know there are some that work with the R-12. So, I assume there may be something that work with R-22 also. I will look around and see what I find. BRB

NU-22 sounds like a compatible replacement. You can read a little here;

Answer 3

is this residential or for a car? R-134a should work. your supposed to change a metering device orifice but it can work without. Its really about the oils need to be compatable.

Answer 4

its an identical DuPont merely gave it a fancy call through fact we desire only one extra call to call r22, probable through fact Chlorodifluoromethane does not precisely roll of the tongue. yet r22 is r22 no count who makes it, and it by no ability is going undesirable the two.
