R32 vs R410A vs R22 vs R290: Comparison Table Because of the flammability of R600A refrigerant, if the refrigerator r600a refrigerant is used improperly, it is easy to cause combustion and explosion. This means these air conditioning systems will become even more state of the art, with a far greater choice of style, efficiency and size. R32 vs R410A vs R22 vs R290 [AC]: Best Refrigerant for You? Or better still, get the designated refrigerant for your car. See below for those coil specifications and rating, Concern around R-32s designation as mildly flammable has waned in recent years as millions of units have been installed and used safely, and due to the fact that actual ignition of R-32 is very difficult, due to its. Proliferation management of refrigerant options is needed, The need to comply with transportation and storage requirements of the refrigerant. Keep reading to discover all that R410a and R32 share and differ in. Book a Call out Technicians need to take the relevant safety measures for the correct transport, storage and handling of a flammable gas. R32 Is the better refrigerant as: I. Dry nitrogen should always be used when brazing to displace the oxygen and prevent oxidisation on the inside of the pipework. Disadvantages: R22 has strong penetrating ability, and leakage is difficult to find. Only use equipment rated for use with (A2L or A2) flammable refrigerants. Both refrigerants allow the fastest conversion from R410A andif the system uses the Danfoss component portfoliogive multi-refrigerant flexibility, allowing late-line customization. Systems using the R32 refrigerant use 20% less refrigerant than they would with R410A. 719 0 obj <>stream Useful for many different purposes. Privacy & Cookie PolicySales Terms & ConditionsTerms of Purchase. Refrigerant is a medium for conveying heat. It is therefore recommended to take into account the information in the installation manuals. This could have a minor impact on energy efficiency and heat transfer conditions. R32 is also flame retardant. %), and recharges may, in some cases, cause the refrigerant composition to change. What are you doing with your contaminated or unusable refrigerant? Regardless of the licensing provisions, employers have a duty of care to ensure that their workers are appropriately trained and have the necessary equipment to use A2L refrigerants. The disadvantages are cited below: - A2L mild flammability rating (difficult to find a Low-GWP A1 non-flammable fluid) - higher compressor discharge temperature from higher vapor specific heat - New oil likely required since existing polyolester (POE) oil is not miscible with R32 Overall, R32 seems to offer more advantages than disadvantages. Additionally, even though R32 is flammable, it has a condition for combustion. You can learn more about GWP from the Environmental Protection Agency (EPA). However, because R-32 had been an extremely difficult refrigerant to handle, its use was not practical until now. The future fate of R32 refrigerant (whether or not itll be banned) is unpredictable. R32 has a 675 GWP. It is less flammable, making it a safer alternative. Download the R32 Refrigerant Information Guide. R32 has excellent thermodynamic properties, but it is still slightly flammable. As a result, a dozen new alternative blends have appeared, many claiming a more close capacity match to R410A, reduced energy consumption benefits and lower discharge temperatures. For more information on that phasedown, check out some of our podcasts. Refrigerant Types, Difference & Properties R22, R32, R410a, R290. Table 1.
