摘　　要：所研究的吸附式制冰机以块状活性炭和甲醇为工质对,采用烟气加热。研究表明,对于本系统,双床循环较为合 适;双床循环中回热回质过程可以有效的改善吸附床的工作性能以及系统的热力完善度,并能将系统的制冷功率提高7％ 到11％。在循环时间为50 min时,回热回质条件下制冷功率为2 kw左右,可以实现每小时制冰15 kg左右。An adsorption ice maker driven by waste heat, which uses solidified activated carbon-methanol as working pair, is studied. Results show that the two-bed configuration is suitable for this ice maker; heat and mass recovery in two-bed configuration could improve the adsorption performance of adsorbers and thermal complete degree of system. The cooling power could be improved about 7%~11% by the heat and mass recovery. The cooling power is about 2 kW with heat and mass recovery when the cycle time is 50 min, the ice production rate is about 15 kg/h at that condition.
