| Use advice for data set | The dataset refers to the manufacture, use and recycling of 1 kg of refrigerant. The dataset can not be used for the estimation of other refrigerants since environmental effects, durability and intended use can be very different. For the calculation of the potential environmental effects through the use of the refrigerant at the building level, the specifications/calculation rules of the respective certification scheme must be followed. For a first estimate the following formulas may be used: I_tot= I_(man.)+ I_use+ I_(disp.) with I_(man.) = I_(A1-A3) × m × a_b/a_r I_use = (I_(A1-A3) × L × a_b ) + (I_B1 × L × a_b ) I_(disp.) = (I_B1 × m × a_b/a_r × E ) + (I_C4 × m × a_b/a_r × (1-E)) + (I_D × m × a_b/a_r × (1-E)) with: I Indicator value of the respective life cycle stage m Mass of the refrigerant [kg] a_b Life time of the building [a] a_r Life time of the refrigerant [a] L Leakage rate [%/a] E Disposal losses [%] Typical values for the required mass m of the coolant in kg per kW nominal cooling capacity can be taken from Table 46 /UBA/ (see figures). Approximate values for the usual service life a_KM, leakage rate L and disposal losses E can be taken from Table 50 /UBA/ (see figures). /UBA/: Environment Federal Office (UBA), Climate-friendly air conditioning (heating and cooling) with natural refrigerants - Concepts for non-residential buildings with server rooms / data centers, 2016 |

| Technology description including background system | The production (modules A1-A3) of the refrigerant takes place in several process steps over 240fa and 245fa. The upstream chain of the basic chemicals dominates the production phase (modules A1-A3). In module B1, the emission of 1 kg refrigerant into the air was accounted for. Since R1234ze is not characterized within the characterization method used (CML 2001 - Apr. 2013), the values for B1 are 0. According to CML 20101 - Jan. 2016, the global warming potential is 0.9 kgCO2 equiv. per kg of refrigerant. In /UBA/ a characterization factor of 7 kgCO2 equiv. Is given. Both values mentioned above can alternatively be used for building-level estimation. The above mentioned proximates of module B1 can be used for both the usage phase (e.g., leakage) and the disposal phase (module C1 removal, disposal losses). Scenarios for use and disposal must be defined at the building level (see field "Use advice for data set"). In the disposal phase (C-modules), any burdens due to removal (usually extraction by means of compressed air in special container systems), transport to the disposal or recycling company, as well as the loads for chemical analysis (e.g. gas chromatography) were neglected. Disposal losses (emissions into the air) must be determined at building level (see above). In module D, 100% material recycling was accounted for. If properly extracted, the refrigerant can be reused directly (without treatment) with the appropriate purity. |
