Pore structure in-situ-regulation of activated carbons for adsorption refrigeration is conducted via an innovative procedure involving precursor blending

CO2 oxidation

and multi-step activation. New carbon higher total pore volume (GHUM)simultaneously realized well-developed mesopores (0.881 9 cm3/g) and micropores (0.295 5 cm3/g) with a high total volume (1.177 4 cm3/g). After depth-activation in SX-100

higher volume of mesopores (1.183 2 cm3/g) was observed with higher total volume (1.183 2 cm3/g). The effects of pore structure distribution regulation on the adsorption/desorption and refrigeration efficiency of activated carbon–methanol working pairs were examined and compared with those on microporous carbon GDWK-02. The results indicated that condensation and diffusion of refrigerants can be well-promoted by carbons with simultaneously well-developed mesopores and micropores with GHUM. Adsorption and desorption capacities of GHUM for methanol were （368.04±4.64）mg/g and （375.92±7.38）mg/g

respectively. Furthermore

GHUM (299.32±123.16) realized higher surface diffusion coefficient (15Dso/Rp2) than SX-100 (242.18±149.33) and GDWK-02 (0.338 7±0.125). When the desorption temperature was 100 ℃

the temperature difference of heat exchange in GHUM type adsorption bed was as high as 50 ℃.Hence

the average temperature of refrigeration room was maintained at 23±1 ℃.Furthermore

the system reached are frigeration capacity (286.12 kJ/kg) and refrigeration power (357.65 kJ/(kg?h)) that can maintain the indoor constant temperature of the cooling air-conditioning system in summer and exhibit good heat transfer and refrigeration performance.
