Multisplit med 2 anslutningar. Upp till 20 meter rörlängd till ett rum och 30 meter totalt. 10 meters höjdskillnad mellen inne och utedel. Många olika kombinationer av vägg innedelar, 4-vägskassetter phase out high GWP refrigerants such as R410A and R134a. R410A refrigerant is used widely for residential and commercial air-conditioning, heat pump applications and air-cooled direct expansion chillers. This paper presents an evaluation of two low GWP refrigerants R447B (GWP=714) and R452B (GWP=675) as replacements for R410A.
Det bör också påpekas att om växthuseffekten för koldioxid omvärderas kommer detta att påverka värdena för alla andra medier.

ODP = 0 Global warming potential GWP = 1725: R-417A: R417A is the zero ODP replacement for R22 Suitable for new equipment and as a drop-in replacement for drop-in refrigerants with low global warming potential (GWP) with a focus on R410A replacement candidates for Unitary A/C & H/P. R32 and the HFO blends can offer near drop-in solutions with a reasonable balance of trade-offs among GWP, efficiency, A2L flammability, and system costs after R454B: slightly lower capacity than R410A but better efficiency; lower GWP; R32: better efficiency and around 10% more capacity than R410A, depending on the application and system design; To learn more about moving from R410A to low-GWP, high-performance alternatives such as R32, see the related links below or contact your local Danfoss representative. Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO 2).GWP is 1 for CO 2.For other gases it depends on the gas and the time frame.

Many of these lower GWP refrigerants have a higher flammability classification, typically A2 or A2L, which means moderately flammable. R410a has a classification of A1, which is non-flammable. Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO 2). GWP is 1 for CO 2. For other gases it depends on the gas and the time frame. Carbon dioxide equivalent (CO 2 e or CO 2 eq or CO 2-e) is calculated from GWP. It The F-gas regulations use AR4 for calculations of CO2 equivalents. Under AR4, the GWP of R410A is 2088 and R32 is 675.
In the case of R410A this mainly results from the 50% share of HFC-125 …
GWP is a relative scale which compares the amount of heat trapped by greenhouse gas to the amount of heat trapped in the same mass of Carbon Dioxide.
