Résumé

In each year, 100 million air conditioning systems are sold globally and air conditioners are consuming 1.26 Quadrillion watt-hours of electric energy. While the vapor compression technology is a major player for the air conditioning systems, there are great interests on a more environmentally friend cooling technologies that use working fluids with low global warming potential and are more efficient. Cooling technologies using solid state materials are called solid-state cooling technologies. Thanks to recent development in solid-state materials, caloric cooling technologies have advanced their potentials. This paper introduces the working principles and recent advancements of caloric cooling technologies and a performance comparison of such technologies with current vapor compression technology. For the comparison, two performance indices, normalized material level COP and system level COP, are used. Comparison results show that magnetocaloric cooling is most prospective among technologies investigated. Although there have been great advancements in material properties for solid-state cooling technologies, they are applicable only to small temperature lift applications and require more development in both materials and system integration.
