“…CO 2 , DME, C 2 H 4 , R32, H 2 O, CH 4 , R134a, and SO 2 were selected as solute-based binary absorption systems. In accordance with the VLE data of relevant systems, 33 sets of isothermal VLE data for binary systems were collected. ,,,,− The eight solute-based binary absorption systems were classified as solutes (CO 2 , DME, C 2 H 4 , CH 4 , and SO 2 ) and refrigerants (R32, H 2 O, and R134a). The solutes were based on the absorption process technology, whereas the refrigerants were applied in the absorption heat pump technology.…”
