Data sources for Table 2.I-1 Chemical Formula, Chemical Name, and Boiling Point: ISO 817 (ISO 817:2014) is used as first priority, ISO 5149 (ISO 5149:2014) as second priority and ASHRAE 34 (ASHRAE 34- 2016) as third priority. Molecular Weight: Calculated from the sum of atoms making up the molecule (based on the chemical formula). The atomic weights are from IUPAC (Wieser, 2013). ATEL/ODL and LFL: Taken from ISO 5149 (ISO 5149:2014). Safety Class: ISO 817 (ISO 817:2014) is used as first priority, ISO 5149 (ISO 5149:2014) as second priority and ASHRAE 34 (ASHRAE 34-2016) as third priority. Atmospheric Lifetime: Values are taken from (WMO, 2018) where available, Table 5.1 and Table 5.3 in (WMO, 2014) is used as 2nd priority, (IPCC, 2014) is used as 3rd priority, (WMO, 2011) is used as 4th priority, and (IPCC, 2007) is used as 5th priority. Radiative Efficiency: Values are taken from (WMO, 2018) where available, (IPCC, 2014) is used as 2nd priority (IPCC, 2007) is used as 3rd priority where (WMO, 2018), (IPCC, 2014) and (WMO, 2011) do not give radiative efficiencies. 3rd priority is (Patten, 2010) (HCC-1130(E)). GWP 100 Year: Values are taken from (WMO, 2018) where available, Table 8.A.1 in (IPCC, 2014) is used as 2nd priority, (WMO, 2011) as 3rd priority the direct GWP values for hydrocarbons in (Colbourne, 2018), and Table 2.12 in (IPCC, 2007) as 4th priority (HE-E170). 60 2018 TOC Refrigeration, A/C and Heat Pumps Assessment Report 7 600 3 900 4 600 13 000 4 100 4 300 12 000 12 000 5 800 1 1 210 600 A1 380 A2L 140 8 100 0.5 6 700 0.2 5 600 0.1 11 000 0.6 4 200 0.1 6 700 9 300 9 500 6 100 0.01 1 1 710 1 700 1 600 630 400 NF A1 A1 560 R-513B R-1234yf/134a (58.5/41.5) 108.7 –29.2/–29.1 NF R-514A R-1336mzz(Z)/1130(E) (74.7/25.3) 139.6 29.0/29.0 NF R-515A R-1234ze(E)/227ea (88.0/12.0) 118.7 –18.9/–18.9 NF R-516A R-1234yf/134a/152a (77.5/8.5/14.0) 102.6 –29.4 B1 Refrigerant Designation Refrigerant Composition (Mass % ) Molecular Weight (kg/kmol) Bubble Point/ Dew Point (°C) ATEL/ODL (kg/m3) LFL (kg/m3) Safety Class GWP 100 Year GWP 20 Year ODPPDF Image | Heat Pumps Technical Options
