“…The principle of sorption in Thermochemical ES is based on performing a reversible chemical reaction (desorption) which allows adsorption of heat in the course of decomposition (desorption) process that is endothermic (Hauer 2007;Ding & Riffat 2012). The reversible physic-chemical reaction, C is the thermochemical material (TCM).…”

“…Inter-seasonal heat storage can be an effective tool to reduce heating peaks in dwellings in winter period [28][29][30][31][32][33][34]. Indeed, solar heating potential is high in summer and low in winter, what is just opposite to heat demand (see e.g.…”

More than half of the world's population currently lives in cities. An essential constituent of future sustainable cities is energy efficient and ecologically sound buildings which ensure high levels of comfort and convenience without reducing the standards of living. At present, a significant part of primary fossil fuels is spent for heating/cooling of buildings, thus, greatly contributing to total GHG emissions. In this paper, typical heat losses in dwellings are considered taking the United Kingdom and the Russian Federation as examples. The role of adsorption-based technologies for more rational use of heat in buildings is discussed. Fundamentals of inter-seasonal adsorptive heat storage (AHS) are briefly considered. A tentative upper limit of the AHS storage density is estimated. Current practice of inter-seasonal AHS and novel smart adsorbents promising for this emerging technology are overviewed. Since a portion of the heat losses in ventilation system significantly increases in modern buildings, a new approach to regenerating heat and moisture in this system is discussed. Finally, optimization trends of the AHS in buildings are briefly considered.

Kinetic study of lithium orthosilicate pellets for high‐temperature chemical heat pumps

Lithium orthosilicate/carbon dioxide/zeolite (Li4SiO4/CO2/zeolite) chemical heat pump (CHP) systems have been discussed for storage and transformation of surplus thermal energy (at ∼650°C) generated from renewable and nuclear energy systems. Tablet forms of Li4SiO4 (referred to as K‐tablets) have been developed with a new pelletizing method for practical application in packed bed CHP reactors. To understand the carbonation and decarbonation mechanisms of K‐tablets, a double‐shell model was suggested and used for explaining experimental results. Isothermal carbonation, decarbonation, and cyclic experiments were conducted under several reaction temperatures for characterization of the K‐tablet. The developed K‐tablet exhibited superior carbonation and decarbonation performance compared to pure Li4SiO4 powder at low temperatures, even when the powder was formed into a tablet shape. The K‐tablet also demonstrated enough durability and a stable reacted conversion value (Δx = 0.75) during cyclic experiments under all temperature. Higher kinetic performances of the K‐tablet than those of pure powder at 650°C and 600°C were also confirmed. The K‐tablet exhibited a high Woutput‐max of 9.82 kW/kg‐tablet at 650°C on the 10th cycle and that value was higher than that of the pure powder (3.25 kW/kg‐Li4SiO4) under the same reaction temperature. The developed K‐tablet has sufficient potential as a CHP material for heat transformation of thermal energy at 600°C to 650°C to >700°C.
