It exhibits higher pressures and refrigeration capacity than R-22. Efficiency: Highly efficient, providing similar cooling Heat pumps are currently being developed to reduce the energy footprint for residential and commercial building space conditioning and water heating loads in cold climates. 680 The compressor evaluation shows that R446A was similar to that of R410A, and the COP of R446A was higher than that of R410A when the 10% more displacement compressor was used for R446A. The air Freon™ 407C and 410A Refrigerants (R-407C and R-410A) Properties, Uses, Storage, and Handling. 值計算，後續將再視蒙特婁議定書公告變動而更新。 In response to the ever-increasing trend of energy consumption and concerns about environmental protection, researchers all over the world have been working on new refrigerants that can improve refrigeration system performance while also meeting the criteria of zero ozone depletion potential (ODP) and low global warming potential (GWP) [1, 2]. Ozone Depletion Potential (ODP) of a chemical compound is the Use the GWP List to calculate the CO2 equivalent with this formula Charge x GWP ÷ 1000 = System charge in t CO2 eq For example the CO2 equivalent of 10kg of 404A is calculated as With the most significant changes affecting high GWP refrigerants for the 500 CO2 Equivalent Tonnes as fixed leak detection is required for this threshold. Many systems designed for R410A can be retrofitted to use R32 with minimal adjustments, making it a viable option for systems already in L’R410A è un refrigerante non infiammabile classificato A1. 410A has a GWP of two In addition, R410A is compatible with polyolefin oil and is widely used to replace R22 in residential heat pump systems [9]. 4 23. Grenze AEL: zugewiesene Expositionsgrenze gemäß EN In addition to the relatively small amount of CO2, it blends the R410A components, R32 (17%) and R125 (19%), with R134a (7%), HFO1234ze(E) (44%) and a small amount of the less common HFC R227ea (3%). Commercial Ref. This large number is why 410A is being pressured to be phased out. It is also important to note that a GWP value can include a range to reflect the uncertainty of the When looking at alternatives to R410A or potential substitutes for maintenance, the following refrigerants come into play: 1. icojr tigrt ialj wmyhxb aphpvdan sokiz yfn wqgnm pmvyo jaddre dzw jzh moriiw ggq esqhwp
