More so, comparing R410a vs R22 will help you discover more reasons why R410a should no longer be in use. R32 will not ignite if the concentration in the room remains below the lower flammability limit. R32 typically costs more than R410a. 3.R32 provide 5% higher energy efficiency than R410a. See below for those coil specifications and rating. R32 is controlled under Australias Ozone Protection and Synthetic Greenhouse Gas Management legislation. Technology and components suitable for lower-GWP refrigerants are well developed and have been available on the market since 2018allowing OEMs to start creating compatible systems. Reproduction in whole or in part without permission is prohibited. Lower Global Warming Potential: In fact R32 has a GWP two thirds less than R410A, which means a far lower harmful effect on the atmosphere. On the installers side, handling R32 requires the use of specific equipment, different from that used to work with R410A. However, there is currently no perfect drop-in replacement for R410A. But do read on, you may be more interested than you initially think once you find out what were talking about! The list of suitable replacements for these refrigerants is substantial. If a gas leak occurs within the indoor unit the refrigerant can pool and become trapped, reaching flammable concentration levels. What is R32 Refrigerant? - Bioaire Air Conditioning Solutions Looking to learn more about the performance of your R-32 equipment or considering a refrigerant change down the road?

Due to the flammability and high operating pressures of R32, existing equipment (e.g. We will be honored to advise you on the most suitable type of refrigerant for your needs. Here are the differences between the two refrigerants: The ozone depletion potential (ODP) of R32 is zero, and its global warming potential (GWP) is on average. The chemical composition of R32 is highly toxic, slightly flammable, and has a safety level of A2L. Eco-friendly as compared to R410 and R22. 0 Both R410a and R32 are non-flammable and non-toxic. Better cooling at high ambient temperature. This includes ensuring that the gas is not exposed to open flames or other ignition sources. Energy Efficiency: Systems that run on R32 require approximately a quarter less charge compared to air conditioning systems run on R410A, this means the same volume of the cheaper gas will also last far longer. However, reports show that R32 refrigerants may be banned by the European Union in 2025. All of them are low-GWP alternatives with interesting performance and efficiency capabilities. Storage of oil is easy. From all indications, R32 seems to be more eco-friendly and suitable for home air conditioners. 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. Todays most common AC refrigerants are R22 (also called Freon) and R410A. R32 has great cooling capabilities. 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. Refrigerants are liquids or gases that make the cooling power of AC units possible. Disadvantages Multiple significant leaks (50 wt. R32 is a popular choice, due to its availability, performance and efficiency, but R454B and R452B also offer convenience and, potentially, low system qualification costs. R290 Refrigerant | Advantages and Benefits | Pros and Cons - Frioflor It was introduced to replace R22 which was banned because of its contribution to greenhouse gases.
