Most likely the system would not working properly and you would also probably cause damage to it. A/C system components are designed with the specific characteristics of the refrigerant. Using a refrigerant with different characteristics will cause problems. These two refrigerants do have very different boiling points.
An environmentally more benign refrigerant for replacing refrigerant R410A includes a majority portion of refrigerant R32 and a minority portion of refrigerant R134a, the volumetric capacity of the replacement refrigerant permitting it to be used as a near or exact drop-in replacement for refrigerant R410A in terms of ...
RS-53 (R470A) has a similar thermodynamic performance to R410A with matching energy efficiency and cooling capacity. RS-53 (R470A) is compatible with the materials commonly found in R410A equipment.
Yes you can use a R134a gauge to measure the PSI to charge R410a refrigerant. But that being said, your R134a gauges will have a maximum reading, if the PSI goes beyond that, it could damage the gauge.
R134a is a pure refrigerant that is sometimes used in blends, while R410a is itself a blend. R134a has a boiling point of -14.9 degrees Fahrenheit, whereas R410 boils at -61.9 degrees. At room temperature R410a has a pressure of nearly 200 psi, while R134a is around 70 psi.
There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a, and R-744. More on these replacements later.
R-410A refrigerant is a blend of hydrofluorocarbon (HFC) compounds R-32 and R-125. It has been used as a replacement for R-22 (commonly known as Freon).
In December 2022, the EPA unveiled a refrigerant ban that will go into effect between 2025 and 2026 (depending on the industry). The result? R-410A is out, shaking up the HVACR industry, which relies heavily on this refrigerant.
No, the compressor will fail. These two refrigerants have very different properties. One of R22 and R134a is high pressure and the other is low pressure. They don't mix chemically and don't have the same boiling point, leading to inefficiencies and eventual compressor failure.
We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line. During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG.
If you use R-22 in the same system as R-410a, the compressor is going to be trying to work two different fluids through the same coils as both refrigerants respond differently to different mechanical situations. As you might imagine, this isn't going to go well for your air conditioner or heat pump.
For cold rooms and other small to medium commercial refrigeration applications, R448A and R449A and R452A or R134a are excellent alternatives to R404A, with from 50 to 65% reduction in GWP. R513A, newer alternative, is also very appropriate in medium back pressure (MBP) applications.
Cooling systems shifting from R-410a to newer refrigerants like R-454B refrigerant and R-32 refrigerant will be implemented in 2025. These new coolants are engineered to be friendlier to the environment and meet updated regulations about global warming.
R134 was specifically designed to replace R12 used in smaller air conditioning units, such as those used in vehicles. R134 is also used in home appliances, mobile refrigeration units and stationary commercial units, such as cold cases in grocery stores.
R-152a refrigerant
For A/C use in automobiles, R-152a is a more efficient refrigerant than R-134a. It has zero Ozone Depletion Potential (ODP) and a low GWP of 124.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
In the United States, vehicles produced after 2021 no longer contain R-134A in the air conditioning system. In other parts of the world, including the United States, there are restrictions around using 1,1,1,2-tetrafluoroethane. Specifically, in California, retailers can deny selling customers canned R-134a.
However, the mixture R32/R134a in the NRC will result in a better performance. The maximal COP can be improved in a range of 8–9% over that of the CRC, and the volumetric refrigerating capacity can be approximately increased by 9.5%.
The same two refrigerants and 19 others are being listed as unacceptable in new cold storage warehouses from January 1, 2023. The banning of R134a, along with 27 other refrigerants, in new domestic refrigerators and freezers from January 1, 2021, is expected to open the way for the use of hydrocarbon refrigerants.
Yes, R-410A will still be available for maintenance and repairs for many years. R-410A won't actually be phased out of production until the 2040s. Also, contractors can still reclaim and reuse refrigerant from older systems.
The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B.
R-22 (Chlorodifluoromethane), also known as R22 Freon or HCFC-22 Freon, was a common refrigerant for HVAC systems. It is now a banned refrigerant that is illegal to import or manufacture.
More About the Phase Out
Unfortunately, this refrigerant contains high levels of hydrofluorocarbons (HFCs) known to deplete the planet's protective Ozone layer. Many regulations (including the Montreal Protocol and the Kigali Amendment) have been passed to contain global warming.
It is observed that R410A has lower surface tension, liquid density and viscosity but higher saturated vapor density and viscosity than R134a. To explore the effects of the fluid properties, the non-dimensional analysis based on the Buckingham PI theorem is applied.
A small amount of R 22 left in a 410A system will not sludge the oil. This is because most POE oils are mixable (meaning they mix well) with any refrigerant even R 22.
