“…Figure 3 displays the climate change impact assessment results of the parameterized LCA models of the heating technologies compared to literature values (Caduff et al., 2014; Castelli et al., 2020; Famiglietti et al., 2021; Greening & Azapagic, 2012; Osman & Ries, 2007; Wernet et al., 2016). Overall, the climate change impact of gas, oil boiler, and wood heater are in relatively good agreement with the ones found in the literature: 66 gCO 2 ‐eq/MJ are estimated for the parameterized model for gas compared to values ranging from 55 to 82 gCO 2 ‐eq/MJ reported in Castelli et al.…”

“…The environmental impacts were quantified using the EU recommended ILCD v2.0 2018 impact assessment methods (Fazio et al, 2018;Moreno-Ruiz et al, 2020) with a focus on climate change, ionizing radiation, ozone depletion, acidification, and freshwater eutrophication. This selection was made to include most of the environmental impacts covered in the scientific literature and product environmental profiles (Famiglietti et al, 2021;Greening & Azapagic, 2012;Havukainen et al, 2018;Miralles et al, 2020;Osman & Ries, 2007;Sauter, 2015). In addition, these impact categories cover most of the trends observed in the others except for wood heating, whose impacts on non-carcinogenic human health, photochemical ozone creation, land use, and respiratory effects are larger than for the other impact categories (Wernet et al, 2016).…”

Life cycle assessment (LCA) is a standardized, holistic, and multi‐criteria approach to estimate the environmental impacts of a system over its entire lifecycle. Modeling the environmental impacts of future scenarios and evolving systems in LCA is challenging due to lack of knowledge around technological evolutions and changing backgrounds influencing the foreground system. The method proposed here tackles these issues by combining parameterized life cycle inventories (LCIs) of foreground and background systems to assess how background changes, for example in the energy sector, affect the environmental impacts of the foreground. First, parameterized LCIs for the heating and energy sector were developed to flexibly estimate the environmental impacts of heating, gas, and electricity trajectories. Assessing their environmental impacts is essential to avoid any burden shifting to other impacts. Thanks to their parameterization, these models can represent different geographical, temporal, or technological contexts. Second, the combination of these parameterized LCIs was implemented using the Python library lca_algebraic, designed to enhance computational efficiency and calculation speed of LCAs. lca_algebraic’s features were extended to link parameters to specific LCIs and, hence, ease their import and export and facilitate teamwork. In a final step, the developed LCIs and lca_algebraic library were used to estimate the environmental impacts of French heating scenarios from 2018 until 2050, as a test of the approach. The parameterized models developed within this work are available on a Git together with published reference datasets for comparison, so that the method can be adapted to evaluate similar energy trajectories for other countries or regions.

“…This kind of visualisation may be misleading as correlations between alternatives in foreground and background systems do not appear. The seven studies considering dependent samplings used DA or similar methods in order to compare alternatives, which were visually compared by plotting DA results in graphs [55] or in matrices [36]. Another option was to plot the distribution of impact ratios [56,57], or the distribution of impact differences [39,58,59] between pairs of alternatives.…”

“…2 From an environmental point of view, the climate change and the preservation of natural resources require the implementation of a new energy transition policy. 3 In view of their operating flexibility, the absorption chillers present the best alternative to conventional compression ma-chines, since on the one hand, they guarantee 4 a high efficiency for low thermal levels, and on the other hand, they are characterised by their low consumption of energy with lower maintenance cost viewing their robustness. 5 Moreover, the absorption machines used in air conditioning systems allow significant savings in electrical consumption compared to traditional mechanical compression machines.…”

For major thermal engines used in industrial sectors, the use of chillers has been growing steadily over the previous decades. Indeed, this is linked strongly to their large energy performance despite their investment costs, which are still high, in particular for low powers. Performance coefficients for absorption chillers are relatively low, and their profitability depends on the costs of the main equipment and more particularly on the price of the absorber. Several studies focusing on the development of mass contactors are underway with the principal objective of further improving their performance of mass and energy transfer. Relating to the mass and heat transfer, it is specified that the contact between the phases in circulation is ensured by different types of contactors. The transfer performance is correlated with the heat and mass transfer coefficient on the one hand, and the specific exchange area, i.e., the exchange area per unit volume of the contactor on the other hand. These contactors are distinguished by their mode of contact between phases (bubbling, spraying, falling film, etc.). While the exchange coefficient depends on the hydrodynamics regime in the contactor (flow regime and physicochemical properties of phases), the specific exchange area is dictated by its operating mode. Any limitation of its use for a specific application (physicochemical phenomena, such as crystallisation, deposited dust, etc.) requires research and development of better devices more adapted. Moreover, the most used contactors in chemical engineering are plate columns, packed columns, falling film columns, spray columns, etc. In order to intensify exchanges, a new absorber of the pulverised type is to be explored in relation with the physicochemical properties of the phases, and of their hydrodynamic flow conditions in the sprayed column. Therefore, an experimental study of the influence of operating variables (nozzle diameter, fluids flow rate, their concentrations, size of droplets, etc.) on the overall coefficient of mass transfer in gaseous phase in the absorber of the absorber chiller was conducted. After having fixed the pressure in the absorber, the first part of the study allowed developing new correlations linking the experimental results of the K G • a to all operating variables (  L,  G, d d , etc.). The second part was devoted to the simulation of the absorption chiller functioning by introducing the concept of energy and exergy yields based on the mass transfer correlations.Keywords H 2 O/LiBr binary system, liquid vapour equilibrium, hydrodynamics of the spray absorber, overall coefficient of mass transfer, modelling
