This line of research aims to address the problem that arises in the near future, as there is currently no clear alternative to current refrigeration fluids and systems that is safe, efficient and environmentally friendly. This will respond to challenges related to: (1) renewable energies, (2) minimization of the carbon footprint, (3) modernization of the economy, (4) development of sustainable vehicles in urban and rural mobility, (5) implementation of eco-efficient technologies, (6) decarbonization, and (7) zero consumption building.<\/p>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading has-text-align-center has-x-large-font-size\"><em>Consolidated lines<\/em><\/h2>\n\n\n\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"translation-block\"><strong>1) Experimental study of associated mixtures<\/strong>.
