Is R502 banned?

HCFCs such as R22 and R502 have been prohibited from use in new equipment since 2001 and since the 1st January 2015 the use of reclaimed or recycled HCFC refrigerants was also banned.

What replaces R290 Freon?

R290 (propane) can also be used as a substitute refrigerant. Being an organic compound (hydrocarbon), it has no ozone depletion potential and a negligible direct global warming effect.

What do letters mean in refrigerant?

A suffix with a upper case B and a number indicates the number of Bromine atoms when used. A suffix with an uppercase letter such as A, B, or C indicate the different percentages of refrigerants that are blended together. This is why you could see refrigerants that have a very similar name such as R-401A and R-401B.

What replaces R502 refrigerant?

R404A refrigerant is accepted as an alternative to R502 in the new equipment. It can be used also for charging of some systems operating on R502, such as commercial refrigeration equipment of big universal shops, refrigeration facilities of food industry factories, transport refrigeration facilities.

Why is R502 needed to be phased out?

R-502 contains CFC-115 and, as a result, will be phased out of production at the end of 1995. R-502 is widely used as a low-temperature refrigerant in the supermarket and·transport industry. The need to replace R-502 has resulted in the production of a number of blends of HCFC and HFC refrigerants.

What type of refrigerant is R507A?

azeotropic HFC mixture
R507A refrigerant is an azeotropic HFC mixture. It has replaced refrigerant R502 in low and medium temperature applications. R507A has a wide range of applications, and it is also suitable for wet evaporation systems. It has good heat transfer properties in the context of condensation.

What is refrigerant R507A?

Forane® 507A refrigerant (R-507A) is a non-ozone depleting, azeotropic blend of HFC refrigerants R-125 and R-143a. R-507 is blended to closely match the properties of R-502, making it a good refrigerant for some medium and most low temperature refrigeration applications.

What is better R134a or R290?

Compared to R22 and R134a, R290 results in a 40% reduction in refrigerant charge. R600a results in a 45% reduction in charge compared to R134a, and a 60% reduction compared to R12.
