It is essential that blend refrigerants be charged by removing only liquid from the cylinder.
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.If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22. Refrigerant R407C has a good energy efficiency ratio as well as a low compression pressure and In case of replacement the R22 must always be switched to Due to its relatively high GWP value, however, R407C will be replaced with refrigerants with a lower GWP value.R407C is a commonly used refrigerant mixture for air conditioning systems, water cooling equipment and, for example, in the high and medium temperature cooling solutions of ships. It is found after the careful observation that R22 performs somewhat better than R407C in many aspects i.e. 1. It is a zeotropic blend of difluoromethane (R-32), pentafluoroethane (R-125), and 1,1,1,2-tetrafluoroethane (R-134a).

no technical reason to replace the HCFC refrigerant. This cookie simply holds a list of blog post ID's and does not contain any information that could personally identify a user. Equipment manufacturers will also tell you that unless the oil being used in your HVAC system is POE oil you cannot use a R22 replacement refrigerant in the system in most cases (M099 is the exception). This cookie simply holds a list of blog post ID's and does not contain any information that could personally identify a user. From 2006 though, the market moved to R410A refrigerant (also an HFC) as it offered higher efficiencies, achieved by operating at higher pressures. The reason is because I already have R22 gas available and if I buy a R407c cylinder I'll be stuck with it, unlikely to use it for anything else any time soon. Darment on YouTube Refrigerant R407C has a good energy efficiency ratio as well as a low compression pressure and GWP. It's sad. 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. Home > R22 Replacement Drop-in: Sort By: Page of 1 : R422B refrigerant, 25lb Cylinder, R22 Replacement NU-22B® Replaces R-22, R-407C, R-422D and R-417A.

R407c was specifically designed to replace R22 and provide 'identical performance' to R22 - same pressures, same equipment. When replacing HCFC-22 with Genetron ® 407C or 422D, use the same charging procedures that you would use for the refrigerant being replaced. to have a mixture of R22,R407C and R422D. I'm not worried about a slight drop in performance but I don't want to cause damage to the system. For one, R 22 is its own refrigerant whereas the replacement refrigerants are made up of several different kinds of refrigerant designed to mimic operating pressures/temperatures of R 22. Darment on Facebook The outcome of R407C as a drop in replacement of R22 has been reviewed in this paper. By continuing you agree to the Copyright © 2020 Elsevier B.V. or its licensors or contributors. Difluoromethane serves to provide the heat capacity, pentafluoroethane decreases flammability, tetrafluoroethane reduces pressure. Doing so could save you a considerable amount should your system develop a leak in the years ahead. The releasing of refrigerants in the surroundings … ozone depletion potential (ODP) and global warming potential (GWP). You can still recharge your HVAC system using R22 but it will be expensive. As per Montreal Protocol, R22 is going to be phase out due to its unfavourable impacts related to environment e.g. Darment on LinkedIn These cookies do not contain any information that could personally identify a user.
The following is a set of general guidelines to assist in the replacement of R22 condensing units with equivalent R407C units. No need to say this will result in catastrophic failure of the compressor and most likely you'll need to replace the whole unit. These services are used to collect statistical data about how this website is used and to track users that have arrived on the site via a Google AdWords link. With this refrigerant there is no need to change the oil. However, once the decision has been made to make the change from R-22 to HFC R-407C, the fol-lowing guidelines are recommended.

Spletzer Sr. Technical Sales Engineer stephen.spletzer@arkema.com (610) 878-6980 Hotline –(800) 738-7695 FMI Energy & Store Development Conference When working with Genetron 407C or 422D it is important to remember that these are blend refrigerants.
