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 regeneration performance of solid desiccant materials under application of the microwave and hot-air methods. Hence

a model was established

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: 857-1 204 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 regeneration method is 2.51-3.21 times that of the hot-air technique.
