7 Within the context of the HVAC sector decarbonization, the market of solar driven 8 heating and cooling systems has expanded significantly over the last years. The 9 ZEOSOL system has as its key principle the coupling of a 12.5 kW c hybrid zeolite-water 10 adsorption chiller with a 40 m² solar field of vacuum tube collectors. The impact 11 assessment has been conducted using ReCiPe 2016 method, using as reference system a 12 conventional reversible heat pump of equal cooling capacity. The

The analysis indicated that 13 the ZEOSOL system has a smaller environmental footprint in terms of impact categories 14 such as global warming and ozone depletion potential, with a 51.2% and a 37.4% 15 decrease of the equivalent emissions in comparison with the reference respectively. This 16 is mainly due to the significant reduction in electricity consumption, given its high solar 17 fraction, in contrast with the grid driven conventional system. On the other hand, the 18 examined system performs worse in impact categories such as eco-toxicity and mineral 19 resources scarcity, as a result of the use of large masses of copper based materials, 20 mainly for pipelines and the solar field. On the contrary, the conventional system uses 21 significantly less materials and therefore has better performance in the influenced 22 categories. 23 24
