What is a replacement for R502?

An R-502 Replacement for Limited Condensing Capacity Systems

Freon™ 408A (R-408A) refrigerant is a hydrochlorofluorocarbon (HCFC) option designed to replace the hydrofluorocarbon (HFC) refrigerant R-502.

Is r11 refrigerant still available?

R-11 production was phased out in 1995 but reclaimed R-11 is still available. Older R-11 chillers can continue to be serviced with available R-11 or be retrofitted to R-123 with engineering support from the equipment manufacturer.

What type of refrigerant is r11?

CFC refrigerant
R-11 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. It is a low-pressure refrigerant that was commonly used in centrifugal chillers and before the 1970’s it was used as a propellant for aerosols.

What is the replacement refrigerant for R-123?

HFO1336mzz
More significantly for the refrigeration industry, the Cooling Post has learned that HFO1336mzz is another refrigerant being considered as both a replacement for the HCFC R123 in centrifugal chillers and as a working fluid in high temperature heat pumps.

What is R11?

Refrigerant R-11 is another refrigerant used commonly in the refrigeration and air conditioning systems. The chemical name of R11 is trichloromonofluoromethane (it is methane series compound) and its chemical formula is CCl3F. … R-11 refrigerant is also used as the solvent and the secondary refrigerant.

What is the boiling point of R11?

74.5°F
Low Pressure
Refrigerant BP
R-11 R-11 (100%) 74.5°F

What is r123a refrigerant?

Freon™ 123 refrigerant is a hydrochlorofluorocarbon (HCFC) replacement for the chlorofluorocarbon (CFC) R-11 in centrifugal chillers. Benefits of using Freon™ 123 include: Low ozone depletion and excellent environmental properties.

Is R22 a Freon?

If your home’s air conditioning unit is more than 10 years old, there’s a good chance it uses R22, commonly known as “Freon.” R22 is an A/C refrigerant — a substance used for cooling in air conditioners— that was once widely used in air conditioning units in homes and businesses alike.

What is R1233ZD refrigerant?

R-1233zd belongs to a new family of HFOs (hydro-fluoro-olefins) that have low GWP. R-1233zd is used in low pressure centrifugal chillers for large air conditioning installations. This product is non-flammable and should be used only in new equipment (does not match properties of R-11 or R-123).

Is R134a a HFC or HCFC?

Common HFC refrigerants are R-32, R- 125, R134a, R-143a, and R-152a. A blend that contains different HFCs is considered an HFC refrigerant. ODP (Ozone Depletion Potential) and low GWP (Global Warming Potential) and so offer a more environmentally friendly alternative to CFCs, HCFCs and HFCs.

What is r20 refrigerant?

R-20. Chloroform (Trichloromethane) CHCl3. 67-66-3. 0.51.

What is R600a refrigerant?

R600a is an HFC-free refrigerant with no ozone depletion potential and a lower global warming potential compared to earlier refrigerants. … GE Appliances, a Haier company has been transitioning to environmentally friendly refrigerants in household refrigerators and freezers.

Is HFC-134a the same as R134a?

R134a is a HFC, used in automotive air conditioning and as a replacement for R12 and R22 in medium and high temperature refrigeration applications, such as commercial and domestic refrigeration and chillers. R-134a is an HFC refrigerant, which requires polyolester (POE) lubricant to be used in the compressor.

What does HFC-134a stand for?

SUMMARY. Hydrofluorocarbon-134a or 1,1,1,2-Tetrafluoroethane (HFC-134a) has been developed as a replacement for fully halogenated chlorofluorocarbons because, compared with chlorofluorocarbons, its residence time in the atmosphere is shorter and its ozone depleting potential is insignificant.

Is r410 an HFC?

R410A is a HFC blend, used mainly in air conditioning systems; it may also be used as an alternative to R13B1 in low temperature refrigeration.

What happens if you mix R134a and R-1234yf?

The mixing of R-134a with R-1234yf will change refrigerant pressure and may result in evaporator freeze-up on pressure control systems, reducing system airflow.

Is all 134a refrigerant the same?

Are all R134a refrigerants the same? Yes, almost all the r134a refrigerants are the same. However, the properties of leak detection sometimes change in the refrigerant. So, you can use the leak detector.

What is 134a gas airsoft?

HFC-134A. Also known as duster gas or air in a can, this is the weakest gas on the list. It’s common air and usually found at plenty of shops. … Also called HFC-22 or top gas, most gas guns out in the market can use this without the help of upgrades—that is, except TM pistols which perform better with HFC-134A.

Can R134a be used in place of R1234yf?

yes R1234yf Freon gas can be replaced by R134a; the newer systems were designed with this in mind so no, there will be no damage to the compressor but some time in the future doing so may become illegal. >>

What happens if you put 134a in an R12 system?

R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.
