Thermodynamic and kinetic study of CaCl2-CH3OH adducts for solid sorption refrigeration by TGA/DSC

•Thermal behavior and sorption characteristics of the CaCl2-CH3OH system are studied by TGA/DSC.•SCPs and COPs are derived from thermogravimetric data.•Cyclic reversibility is estimated in repeated methanolation/demethanolation cycles.•Constant CH3OH sorption and evolution of heat energy over cycling are observed.•The working pair CaCl2-CH3OH possesses a good cyclability and reversible cooling output over 18 cycles.
