“…To avoid such a phenomenon, different types of evaporation processes can be adopted in the evaporators of adsorption devices. Among the different types of evaporator (flooded, capillary tubes), the falling-film concept appears to be the most suitable thanks to the superior global heat transfer coefficient [8,9].…”

“…When using multiple beds, cycle lengths and their spacing can be adjusted to maximize cooling efficiency and working time of the evaporator in the cycle [8]. The other parameters influencing the performance, size, and weight of the adsorption chillers include, but are not limited to, the design of the heat exchanger in the bed [10] and the materials of which the bed is made [11], the size of sorbent particles [12], the velocity of heat transfer fluid that heats or cools the bed [13], and the type of evaporator [14,15]. As can be seen, the performance of adsorption chillers depends on numerous different factors.…”

“…To efficiently evaporate water at low temperatures, the height of the water column can be reduced until only a thin film with low thermal resistance is left: Thin-film evaporation has been shown to offer high heat transfer coefficients [2] with small required superheats [3].…”
