Vipinraj A R Mangalam College of Engineering Iso butane is R600a, when you compare the change of temperature with pressure the change is drastic in the case of iso butane than in R134a. secondly.
A non-ozone depleting azeotropic mixture of R-125 and R-143a. It has been primarily designed to replace R-502 in low- and medium-temperature commercial refrigeration applications such as supermarket display cases and ice machines. For new equipment and retrofits. R-507 is suitable as a replacement for R-22 in flooded refrigeration systems.
Created in the 1930’s, R22 refrigerant was a replacement for the dominant refrigerants of the time, which contained ammonia. It was considered a safer and more effective replacement and it worked well for decades until the 1980’s when an environmental problem was acknowledged.Freon-500 Genetron-500, Forane-500 Freon is a registered trade name for E. I. DuPont. Genetron is a registered trade name for Forane is a registered trade name for Elf Atochem.Since refrigerant R22 has ozone depletion potential, it is use is being stopped in the phase manner. This article discusses various options for replacement for R22 refrigerant. Apart from describing R22 alternative refrigerants, the article also describes EPA instructions for R22 replacement. There are several refrigerants that do cause the depletion of the ozone layer and that can be used as.
The refrigerant R134A is called tetrafluoroethane and is classified as one of the HFC gases from the other refrigerant variants. Today, R134A is commonly used in vehicle air conditioning systems, but it can also be used in refrigerators, freezers and other refrigeration equipment similar to R12.Read More
The best replacement for R12 is considered to R-134a. The other two refrigerants that are considered good replacements for R12 are R-401a and R-401b. For vehicles also the most appropriate alternative is R-134a refrigerant. It has been approved by all the vehicle manufacturers for replacing the R12 refrigerant.Read More
AZ50, an azeotrope of HCFC 22, HFC 125 and 143a is the replacement for R-502 which was used in the past for low-temperature applications and is itself an azeotrope of CFC 12 and HFC 152. Both AZ50 and AZ20 an azeotrope and a near azeotrope respectively that match a true compound very closely.Read More
R442A (RS-50) R442A, also known as RS-50, is an HFC blend that is suitable for use in low and medium temperature refrigeration applications such as those used in commercial refrigeration. It can be used as a retrofit replacement for R22, R404A or R507 systems, including commercial and transport refrigeration.Read More
Call 1.888.735.5651 to learn more about your R22 refrigerant replacement options. FAQs: R22 phase-out for air conditioning systems What is R22? R22 refrigerant has been used for years in central air conditioners, heat pumps, mini-splits, car AC systems, and other refrigeration equipment. It’s the key to absorbing and removing heat from a space.Read More
ISCEON MO79 Refrigerant: DuPont ISCEON MO79 is a cost-effective, non-ozone-depleting HFC refrigerant for replacing R-22, R-502, and HCFC-containing refrigerant blends in medium- and low-temperature commercial and industrial direct expansion refrigeration systems.Read More
Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units. Although there are various types of refrigerants, R-32 is a new refrigerant currently receiving the most interest.Read More
RS-44b (R453a) is the newest R22 drop-in replacement refrigerant in the U.S. market. RS-44b has been sold worldwide for the past 5 years, branded as RS-70 outside the US. It is the closest replacement to R22 that operates with very similar discharge pressure, cooling capacity and flow rate as R22.Read More
Refrigerant R-502. Refrigerant-502 is an azeotropic mixture of 48. 8% by mass of R-22 and 51 .2% of R-115. This refrigerant was introduced commercially in the early 1960’s for low temperature applications and is particularly suitable for hermetic compressors. The important properties of R-502 are as follows.Read More
R442A, also known as RS-50, is an HFC blend that is suitable for use in low and medium temperature refrigeration applications such as those used in commercial refrigeration. It can be used as a retrofit replacement for R22, R404A or R507 systems.Read More
