Prototype thermochemical heat storage with open reactor system

A review on the use of calcium chloride in applied thermal engineering

“…Pure calcium chloride has also been investigated as TCM at small scale (40 g of CaCl 2 $2.3H 2 O) [136,143,148]. Although the authors observed gel formation that prevents further water uptake, calcium chloride showed interesting performance compared to other salts (Fig.…”

Study of the reversible water vapour sorption process of MgSO4.7H2O and MgCl2.6H2O under the conditions of seasonal solar heat storage

“…This means that for a packed bed reactor of salt hydrate designed for seasonal heat storage with around 50% of porosity [11] [5,11]. However, this material has some disadvantages for long term storage due to instability and decomposition of the material.…”

“…For MgCl 2 .6H 2 O, the dehydration was carried out with a heating rate of 0.5°C/min until 130°C. This temperature was chosen since previous measurements [4,5] showed the decomposition of MgCl 2 .2H 2 O above 130°C. The rehydration of the dehydrated material was performed with a cooling rate of 0.2°C/min until 40°C, after which the material was kept isothermal at this temperature to avoid overhydration (see section 3.2.1).…”

Modeling and analysis of energetic and exergetic efficiencies of a LiBr/H20 absorption heat storage system for solar space heating in buildings

“…This technology is under development, and only a few experimental studies at the prototype stage have been reported with solid materials (Kerskes et al 2012;LassSeyoum et al 2012;Mauran et al 2008;Michel et al 2014;Zondag et al 2013) or with liquid aqueous solutions (Quinnell and Davidson 2012;N'Tsoukpoe et al 2013;Weber and Dorer 2008). A multicriteria analysis conducted in various working fluids and presented in Liu et al (2011) proposed the choice of a lithium bromide/ water solution for absorption heat storage.…”
