Abstract:

Water and ethanol were selected as refrigerants, 13x molecular sieve, silica gel, activated carbon and adsorbents NA and NB prepared by authors were selected as adsorbents, and the performance of adsorption working pairs in adsorption refrigeration system was studied. The adsorption isotherms of adsorbents(NA and NB)were obtained by high-vacuum gravimetric method. Desorption properties of adsorbents were analyzed and compared by thermal analysis method. The performance parameters of adsorption refrigeration of different adsorption working pairs were studied on experimental device of adsorption refrigeration cycle. The results show: (1) The maximum adsorption quantity of water on adsorbent NA arrives at 0.7 kg/kg, and the maximum adsorption quantity of ethanol on adsorbent NB is 0.68 kg/kg, which is 3 times that of ethanol on activated carbon; (2) The refrigeration volume of NA-water working pair is 922 kJ/kg, the refrigeration volume of NB-ethanol is 2.4 times that of activated carbon-methanol; (3) As friendly to environment and no public hazard adsorption working pair, NA-water and NB-ethanol can substitute for carbon-methanol in adsorption refrigeration using low-grade thermal energy.
