建设了对吸附装置具有内部冷却功能的内冷型固体除湿空调实验系统,以自制活性氧化铝与沸石分子筛作为固体吸附除湿材料,对内冷固体除湿的性能进行实验研究。讨论了常温低湿、中湿、高湿3种不同进口空气工况对固体除湿性能的影响。结果表明:内冷型固体除湿性能高于绝热型固体除湿,对常温低湿空气,氧化铝内冷比绝热下除湿量高出11.25%,沸石分子筛高出了14.14%。对常温中湿空气,氧化铝除湿量高出22%,沸石分子筛除湿量高出25.45%。对常温高湿空气,氧化铝高出20.4%,沸石分子筛高出了24.9%。且活性氧化铝作为吸附除湿材料无论是在内冷或绝热工况均比沸石分子筛表现出更高的除湿能力。
An internal cooling type solid dehumidification air-conditioning experimental system with internal cooling function was established. The self-made activated alumina and zeolite molecular sieve were used as solid adsorption dehumidification materials, and the performance of internal cooling solid dehumidification was experimentally studied. The effects of room temperature, low humidity, medium humidity and high humidity on the dehumidification performance of solid were discussed. The results show that the dehumidification performance of the internal cooling type solid is higher than that of the adiabatic solid, which is 11.25% higher than that of the room temperature, low humidity air and alumina, and 14.14% higher than the zeolite molecular sieve. On the wet air at room temperature, alumina dehumidification capacity higher than 22%, zeolite zeolite dehumidification capacity higher than 25.45%. At room temperature, high humidity air, alumina is 20.4% higher, zeolite molecular sieve higher than 24.9%. Moreover, activated alumina as adsorption dehumidification material shows higher dehumidification capacity than zeolite molecular sieves both in internal cooling and adiabatic conditions.
