A new target-oriented methodology of decreasing the regeneration temperature of solid–gas thermochemical sorption refrigeration system driven by low-grade thermal energy

A novel solid–gas thermochemical multilevel sorption thermal battery for cascaded solar thermal energy storage

“…The sensible heat released by the metallic part of reactor is strongly dependent on the mass of metallic part of reactor. Generally speaking, the mass of metallic part of reactor is about 5-20 times that of reactants according to previous experience in solidgas thermochemical sorption refrigeration [4,11]. Moreover, the sensible heat released by the metallic part of reactor is usually much lower when compared with the reaction heat of reactants.…”

“…Solid-gas thermochemical sorption process stores thermal energy in the form of bond energy of chemical potential using a solid reactive salt and a gas, thus, this kind of storage method usually has the advantage of high energy density in comparison with conventional sensible heat and latent heat energy storage, liquid-gas absorption and solid-gas physical sorption energy storage [9,10]. On the other hand, solid-gas thermochemical sorption energy storage also has the advantage of the flexibility of stored temperature because its working temperature can be easily controlled by changing system operating pressure due to the monovariant characteristic of chemical reaction [11]. Moreover, a stable working temperature can be obtained once operating pressure is given in a solid-gas thermochemical sorption energy storage system.…”

A target‐oriented solid‐gas thermochemical sorption heat transformer for integrated energy storage and energy upgrade

“…21 In this case, a further decrease in the heat input temperature can be attained and a further increase in the heat output temperature can be achieved, thus, a higher-temperature magnitude of energy upgrade of low-grade thermal energy would be obtained. For example, heat input temperature of nickel bromine salt would become 96 C using the proposed multistage pressurereducing desorption method and the temperature magnitude of energy upgrade would be as high as 236 C if the advanced thermochemical sorption heat transformer A-B-C-D-E-F-G-H-M-N is introduced as shown in Figure 11.…”

Heat Transfer, Fluid Mechanics, and Thermodynamics in Our Environment—HEFAT2012

“…In industry, heat transfer, fluid mechanics and thermodynamics are used in environmental studies as engineering sciences to enhance our basic understanding and design capabilities [1] of a broad range of phenomena [2][3][4][5][6][7][8][9][10], equipment [11][12][13], applications [14][15] and systems [16][17] ranging from biological systems [18][19] to common household appliances [20][21], aerospace [22][23], residential and commercial buildings [24][25], mining [26][27], industrial processes [28][29], and electronic devices [30][31]. These disciplines can also be used to conduct techno-economic analyses [32][33][34][35][36][37][38][39] for comparing different types of equipment and systems to allow decisions in terms of capital and running costs in comparison with the cost of financing and impact on the environment [40][41].…”
