What Is 502 Freon Used For?

FAQs Jackson Bowman August 26, 2022

Prior to its discontinuation in 1995, it was used in cryogenic refrigeration (evaporator pressure remains out of vacuum down to -40°F). R-502 offered a lower exit temperature and improved capacity compared to R-22.

Is 502 refrigerant still available?

USA Production ended on December 31, 1995. An azeotropic mixture used in low and medium temperature refrigeration applications.

What Freon is compatible with 502?

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

What is the category of 502 refrigerant?

Product type: CFC

R-502 offers a lower outlet temperature and improved capacity compared to R-22. Commercial refrigeration systems can provide single-stage cryogenic refrigeration using relatively inexpensive compressors.

What refrigerant is replacing R502?

Refrigerant R404A is accepted as an alternative to R502 in the new units. It can also be used to fill some systems that run on R502, such as: B. commercial refrigeration systems of large general stores, refrigeration systems of food industry factories, transport refrigeration systems.

When was R502 phased out?

R502 is currently the most commonly used refrigerant in commercial cold storage; according to the Copenhagen Amendment to the Montreal Protocol, it is to be completed by 1. January 1996 worldwide and according to an EEC regulation from 1992 until January 1, 1995 within the European Union. p>

What is R500 refrigerant?

R500 is a colorless and odorless CFC refrigerant that has been completely phased out under the Montreal Protocol for ozone depletion. R500 is used in commercial air conditioning and in some dehumidifier applications. It is under high pressure and is usually stored in yellow containers.

What is the replacement freon for R22?

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

What refrigerants will one shot Replace?

Freon One Shot™ C (R-422C) refrigerant is a hydrofluorocarbon (HFC) option that replaces many chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), including R-22, in low and medium temperature applications .

What is R449a?

R449a is a mixture of common hydrofluorocarbons (HFC) and the new hydrofluoroolefin molecule R1234yf (HFO), a composition of R32 (24%), R125 (25%), R134a (26%) and R1234yf (25%) ) gases. Refrigerant R449a is non-toxic and non-flammable and has been assigned safety classification A1 according to EN 378 and ASHRAE 34 standards.

What type of refrigerant is R290?

R290 (propane) is refrigerant grade propane used as an alternative to R22 and R502 in low, medium and high temperature refrigeration and air conditioning applications.

What is R507 refrigerant?

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

Is R502 flammable?

R-502 is non-flammable at ambient temperature and atmospheric pressure. However, this material becomes combustible when mixed with air under pressure and exposed to strong sources of ignition.

Which of the following is an approved drop in service replacement for R 502?

For example, HCFC-22 is an acceptable replacement for R-502 in industrial process cooling.

What is 401A Freon?

Freon™ MP39 (R-401A) refrigerant is a retrofit option to chlorofluorocarbons (HCFC) for R-12 in stationary positive displacement air conditioning (AC) and refrigeration systems used primarily in retail food refrigeration applications< /b>.

What replaced Hot Shot 2?

An R-12 refrigerant replacement

R-401A. R-401B. R-409A. R-414A.

What is the most efficient refrigerant?

A. R-32 is the most balanced refrigerant in terms of eco-sustainability/energy efficiency/safety/cost-effectiveness for stationary air conditioners and heat pumps.

What is commonly used as a refrigerant for most refrigerators?

While R-12 was once the first choice for home refrigeration systems, today the most commonly used refrigerant is Freon™ R-134a. Its versatility allows for use in home systems ranging from small under-counter refrigerators to family-size, multi-compartment fridge/freezers.

What refrigerant is used in refrigerators?

Both refrigerators and cars use R-134a as a refrigerant, and adults can buy it at most auto parts stores. The combination of the incompatible refrigerants R-12 and R134a blocks the compressor.

Is r500 a low pressure refrigerant?

Common low-pressure refrigerants are R-11 and R-123. System whose gauge pressure is greater than atmospheric pressure but typically less than 100 psig (689 kPa) at room temperature (74°F [23.3°C]). Common medium-pressure refrigerants are R-12, R-500 and R 134a.
