Summary

Shaped MIL-101 and ethanol were selected as a working pair for adsorption refrigeration in this work. The adsorption isotherm of ethanol on shaped MIL-101 (MIL-101-3) was obtained by high vacuum gravimetric method. The desorption performance of ethanol on MIL-101-3was measured by Thermo Gravimetric Analyzer. The adsorption refrigeration performance and cyclic adsorption stability of MIL-101-3– ethanol were investigated on the simulation device of adsorption refrigeration. The results show: (1) the equilibrium adsorption capacity of ethanol on MIL-101 is 0.74 kg/kg at 25°C. (2) The desorption peak temperature of ethanol on MIL-101-3 is 54.0°C, and temperature of complete desorption is about 100°C. (3) At the desorption temperature of 80°C, the refrigeration capacity of MIL-101-3–ethanol working pair reaches 283 kJ/kg, which is 2.2 times as much as that of activated carbon–ethanol. (4) MIL-101-3 shows no significant reduction of ethanol uptake after 60 cycles, and the Brunauer-Emmett-Teller (BET) surface area only decreases by 3.3%.
