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 type of refrigerant is 502?
R502 is a blend of R22/R115 developed for use in low temperature refrigeration applications.
Can R22 replace R502?
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.
What is 408A refrigerant?
Forane® 408A refrigerant (R-408A) is a non-ozone depleting, near-azeotropic HCFC blend of R-22, R-125, and R-143a that was designed to match the performance of R-502. R-408A is a retrofit solution for medium and low temperature refrigeration systems that are currently using R-502.
Which refrigerant is used in domestic refrigerator?
The refrigerant commonly used for domestic refrigerators is ammonia. Ammonia, frequently used commercially in large freezing and refrigeration plants is also called “anhydrous ammonia” because it contains almost no water (it is 99.98% pure).
When was R502 phased out?
1995
R502 is currently the most commonly used refrigerant in commercial cold storage; it is due to be banned worldwide by January 1st, 1996, according to the Copenhagen amendment of the Montreal Protocol, and by January I st, 1995 within the European Union according to a 1992 EEC Regulation.
Is 502 refrigerant still available?
Older systems with limited condensing capacity, and low- or medium-temperature commercial refrigeration systems used in supermarkets often use R-502, which is now being phased out as part of the Montreal Protocol.
Can you use R404A in a R22 system?
R404A and R507A as substitutes for R22 and R502. These blends are chlorine free substitutes (ODP = 0) for R22 as well as for R502 in medium and low temperature ranges. The efficient application of single stage compressors with low evaporating temperatures is therefore guaranteed.
What is the replacement for 408A refrigerant?
Opteon™ XP40 can also be used as a replacement for “service” blends, such as Freon™ HP80 (R-402A) and Freon™ 408A.
What is 408A plan?
A 408(k) account, commonly referred to as a Simplified Employee Pension (SEP) plan, is an employer-sponsored, retirement savings plan. The 408(k) plan is the SEP version of the popular 401(k) plan. The SEP-IRA only allows the employer to contribute to the plan, while employee contributions are not permitted.
Which refrigerant is best for refrigerator?
The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming….
| Refrigerant | Global Warming Potential | Ozone Depletion Potential |
|---|---|---|
| R-22 | 1810 | Medium |
| R-410A | 2088 | Zero |
| R-32 | 675 | Zero |
| R-134A | 1430 | Zero |
