As the humidity load of an air-conditioning system accounts for 40%-60% of the cooling load of the entire system, exploiting the advantages of solid desiccant can effectively reduce the energy consumption of the air-conditioning system. The major source of energy consumption for the desiccant system is the regeneration energy consumption of the solid desiccant, and the traditional regenerative mode is characterized by high energy consumption, low regenerative efficiency, etc. In this study, comparative tests were conducted on the re-generation performance of solid desiccant materials under application of the microwave and hot-air methods. Hence, a model was estab-lished, and analyses were conducted considering the regeneration effect and energy consumption. Solid desiccants in the same state were tested under hot-air regeneration modes of 50-90 ℃ ( power:857-1204 W) and for microwave regeneration powers of 440-800 W. The test results indicate that the maximum regeneration rate for the hot-air method is 49. 89%-86. 23% of the microwave technique. However, the microwave energy consumption is only 25. 2%-37. 7% of the hot-air method. Thus, the average energy utilization of the microwave re-generation method is 2. 51-3. 21 times that of the hot-air technique.%空调系统湿负荷约占整个空调系统冷负荷的40%~60%,利用固体除湿材料可有效降低空调系统能耗.固体除湿材料的再生能耗是除湿系统的主要能耗,传统的再生方式存在能耗大、再生效率低等缺点.本文采用微波和热风再生的方法对固体除湿材料的再生性能进行了对比实验,从再生效果和再生能耗两方面进行了分析,并建立了模型.相同状态下的固体除湿材料在热风再生工况50~90℃(功率857~1204 W)与微波再生功率440~800 W进行对比实验,结果表明:当达到相同的再生度时,热风最大再生速率是微波最大再生速率的49.89%~86.23%,而微波能耗只有热风能耗的25.2%~37.7%,且微波再生平均能源利用率为热风再生的2.51~3.21倍.
