What is 502 freon used for?

What is 502 freon used for?

Developed for use in low temperature refrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offers lower discharge temperature and improved capacity compared to R-22.

What is R502 used for?

R502 is a blend of R22/R115 developed for use in low temperature refrigeration applications.

Is R502 refrigerant still used?

R-502 was mainly used for vending machines, supermarket freezers, ice machines, and refrigerated transport. R-502 was replaced with the HFC R-404A. The very latest to go in the CFC/HCFC side was R-22.

What replaces R502 Freon?

R404A
R507 is a HFC blend, used as a replacement for R502 and R22 in low and medium temperature refrigeration. With a Global Warming Potential (GWP) of 3985, R507 is under similar scrutiny to R404A.

Which refrigerant is used in domestic refrigerator?

While R-12 was once the go-to choice for residential/domestic refrigeration systems, Freon™ R-134a refrigerant is now most commonly used.

What is r500 refrigerant?

R-500 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-500 is used in commercial air conditioning and in some dehumidifier applications. It Is high-pressured and typically stored in yellow containers.

What refrigerant is compatible with R502?

Higher discharge temperatures than R-502. Use either syn-thetic oil or blend of AB/MO with AB>50%. Genetron® 134a Honeywell R-12 Single Synthetic (POE, PVE) New Equipment Suva® 134a DuPont Component Forane® 134a Arkema Fluid HFC Klea® 134a INEOS Performs well in small hermetic systems.

What Freon is compatible with 502?

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

What is the most commonly used refrigerant?

The most common refrigerants used for air conditioning over the years include:

• Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect.
• Hydrochlorofluorocarbons (HCFCs), including R22.
• Hydrofluorocarbons (HFCs), including R410A and R134.

What refrigerant is used in freezers?

R404A refrigerant
Most modern lab-grade freezers use R404A refrigerant, which has a GWP of 3,920. Ultra-low temperature freezers also use R508B as the secondary refrigerant, which has a GWP of 13,396.

Is r500 flammable?

With a Hazard Class of 2.2, R-500 is non-flammable and non-poisonous. It has a molecular mass of 99.31. Its boiling point at atmospheric pressure is negative 28 degrees Fahrenheit, and its freezing point at atmospheric pressure is negative 107.9 degrees Fahrenheit.

Why was the R-502 used in refrigeration?

Before its phaseout in 1995, it was used in low temperature refrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offered lower discharge temperature and improved capacity compared to R-22.

What is the molecular formula for refrigerant 502?

Refrigerant 502 PubChem CID 38271 Structure Find Similar Structures Molecular Formula C3HCl2F7 Synonyms Refrigerant 502 39432-81-0 Freon 502 CFC Molecular Weight 240.93

Which is the best refrigerant to replace R22?

The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.

What is the chemical formula for refrigerant R11?

Refrigerant R12 or Freon 12 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 CCl 3F.
