摘　　要：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。The internal cooling system type solid desiccant air conditioning experimental system with internal cooling function was built for adsorption unit,using homemade activated alumina and zeolite as solid desiccant materials. An experimental study was conducted on the dehumidification performance of internally cooled dehumidifier. The results showed that： Internally cooled solid-solid dehumidification performance was higher than the adiabatic dehumidifier,at room temperature and low humidity,the dehumidification capacity of alumina in internally cooled dehumidifier was 11. 25% higher than that in adiabatic dehumidifier,and the zeolite was 14. 14%higher than that in adiabatic dehumidifier. At room temperature and intermediate humidity,the alumina was 22%higher than that in adiabatic dehumidifier,and the zeolite was 25. 45% higher than that in adiabatic dehumidifier.At room temperature and high humidity,the alumina was 20. 4% higher than that in adiabatic dehumidifier,and the zeolite was 24. 9% higher than that in adiabatic dehumidifier. The activated alumina,as a desiccant,showed a desiccant capacity higher than that of zeolite molecular sieve,whether in internal cooling or heat insulation conditions.
