As per Montreal Protocol, R22 is going to be phase out due to its unfavourable impacts related to environment e.g. They must either refit or replace their entire air conditioning systems now or be forced to do it after 2020 when the less expensive R22 refrigerant disappears from the market for good. 0000019899 00000 n The U.S. government has placed restrictions on R22 and has issued the requirement that R22 refrigerant must be eliminated from use in cooling systems by the year 2020. The outcome of R407C as a drop in replacement of R22 has been reviewed in this paper. 0000035469 00000 n ozone depletion potential (ODP) and global warming potential (GWP). Lol. The outcome of R407C as a drop in replacement of R22 has been reviewed in this paper. Author Neil A. Roberts. There are currently no restrictions on equipment or use of the following refrigerants: R134A, R407C, R410A, and R417A. This listing is for a new 11 Lb. I believe heatkaft is asking about R22 vs R404A more in terms of how they compare when used for new installations rather than as replacement refrigerants. Refrigerant R407C has a good energy efficiency ratio as well as a low compression pressure and GWP. 2. No, you shouldn’t mix There are NO refrigerants that you are supposed to use to top off an R22 […] It can also be used to retrofit some old R22 systems with an oil change. It's a greenhouse gas, though, and it doesn't work as well as R22. Therefore, there will not be any other solution than direct substitutes. With the phase-out of HCFCs being accelerated in some regions of the World, most notably Europe, many studies have been performed on two alternatives to replace R22 i.e. Super Change™ also rejuvenates o-rings, elastomers, and gaskets, in most cases eliminating the need to replace them when switching to an HFC refrigerant. %PDF-1.4 %���� R417A is the zero ODP replacement for R22 suitable for new equipment and as a drop-in replacement for existing systems. 3. The primary driving force to cause a switch from R22 to R404A in commercial refrigeration … Yes, to answer your question, and we use R407c since it is the closest match to R22 we can find out there. Yes, to answer your question, and we use R407c since it is the closest match to R22 we can find out there. 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. R422B can be used to COMPLETELY replace R-22 refrigerant in new or existing R-22 residential and commercial air conditioning systems as well as non-flooded evaporator chillers. Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. 12.01.2017. There are refrigerants considered by to be more environmentally friendly than R-22, but when I compare the ODP and GWP I really fail to see that R-22 … It has the same capacity. It can also be used to retrofit some old R22 systems with an oil change. For those who already are having trouble with their HVAC unit, then it makes sense to use that as an opportunity to address the R-22 problem at the same time. ©2021 The Chemours Company. For this reason, you should only use drop-ins for quick, temporary repairs and have a different long-term replacement plan in mind. They are not meant to replace any existing relevant standards or recommended good practice.. All work must be carried out by appropriately qualified refrigeration and/or electrical personnel, complying with local and national codes of practice. A wide variety of r407c refrigerant replace r22 options are available to you, such as alkyl & derivatives, alkene & derivatives. 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. R22 refrigerant, sometimes known as R22 Freon or HCFC-22 Freon, is an environmental danger because it contributes to the depletion of the ozone layer. As of 2012, the heating, ventilating and air conditioning (HVAC) industry is in the process of … If you mix R407C with R22 inside your system the molecule of the HFC (R407C) gas will not link with the oil and in just few months of operation you will have a "sludge" like lubricant formation inside the circuit. In case of replacement the R22 must always be switched to POE (polyolester) oil. Freon™ 407C has been a popular R-22 replacement because of its properties, which include: Regulations on the long-term use of refrigerants vary by region and application, and may change over time. Trials with RS-44 have shown energy savings from 10 to 20% compared to R22 when RS-44 is retrofitted into the same system while achieving similar capacity. Be aware that 1) older AC models that use R22 may also not be running at peak efficiency, and 2) the cost of R22 will continue to increase as it becomes less available. Other alternatives / replacements: R407A: Compatible lubricants: POE This alternative to R-22 in positive displacement air conditioning (AC) equipment can also: Replacing R-22 with Freon™ 407C in these systems requires switching to polyolester (POE) oil. 3 Options for R22 Freon Replacement. Replacement for: R22: Retrofit gas or design for new equipment? Freon™ HFC and HCFC Refrigerant Products, Replace R-502 in new and retrofitted medium-temperature applications with evaporator temperatures above -6.7 °CC (20 °F), Work in existing medium-temperature applications, Work in new or existing residential and commercial AC and heat pumps, Similar cooling capacity, energy efficiency, and pressures as R-22 in systems, An ability to be topped off after a leak, multiple times, with minimal impact on system performance, Safety; Freon™ 407C has an ASHRAE A1 safety classification. 1) [46] and they can be use as potential alternative refrigerants. Chemours™ and the Chemours Logo are trademarks or registered trademarks of The Chemours Company. Homeowners that have R22 air conditioning systems can still use their units. R407F – Genetron® Performax™ LT. R407F can also be used as a retrofit solution for R22. 0000011867 00000 n For those who already are having trouble with their HVAC unit, then it makes sense to use that as an opportunity to address the R-22 problem at the same time. 45 0 obj<> endobj Just don’t let anyone mix R22 and another refrigerant because then it wouldn’t be either of those anymore. Cannot be added to R-22 unless fully evacuated and recharged with 422B (NU-22B). R407C is an HFC ternary blend of R32, R125, and R134A and has similar properties as R22 in air conditioning systems and is suitable for R22 retrofits.
