Review on sorption materials and technologies for heat pumps and thermal energy storage

Abstract: Sorption is used for absorption/adsorption heat pumps (sorption refrigeration) and sorption for thermal energy storage (TES). This paper is the first review where the research on both applications is shown together. Sorption has advanced very much due to the immense amount of research carried out around heat pumping and solar refrigeration. Moreover, sorption and thermochemical heat storage attracted considerable attention recently since this technology offers various opportunities in the design of renewable a… Show more

“…In the liquid-sorption energy storage systems, LiCl-H2O pair is often utilized, and the absolute storage capacities of liquid desiccants (absorption) have been reported to be 3-5 times higher than those of an ice storage system, while the energy density was stated to be 220-390 kWh/m 3 [19]. Other working pairs for thermal energy storage systems can be found in the work of Cabeza et al [20]. Henceforth, this review focuses on solid-based adsorption systems, i.e., adsorption systems for thermal energy storage.…”

“…Indeed, sorption, both solid adsorption and liquid absorption, mainly relies on physical and weak chemical bonds, which require limited temperature levels (i.e., below 100 • C) to be split during the charging phase [17]. At the material level, the main activities focus on the development of novel adsorbent materials with enhanced sorption capacity and reduced driving temperature [18]. Particularly, novel composite sorbents, based on a porous structure embedding a hygroscopic salt were deeply investigated, varying both the porous matrix, i.e., vermiculite [19,20], silica gel [21,22], carbon structures [23,24] and the employed salts, i.e., LiCl, CaCl 2 , MgSO 4 , SrBr 2 [20][21][22][24][25][26] .…”

“…Adsorptive heat transformation (AHT) is an energy-saving and environmentally friendly technology that is attracting increasing attention due to its ability to effectively convert and store waste or renewable heat [1][2][3]. The adsorption cooling [4], deep freezing [5], ice production [6], air conditioning [7], heat pumping and storage [8] have attracted a lot of research in recent decades. Nowadays, several adsorptive chillers and heat pumps are available on the market [2,9].…”
