Abstract:

A new system of liquid desiccant dehumidification, called ultrasound atomization dehumidification system, is proposed.In this system, a packed bed is replaced by ultrasound atomization technology, so high resistance and liquid desiccant consumption caused by the packed bed are avoided.A mathematical model is established to predict the efficiency and the liquid consumption of the dehumidification process under ideal conditions.Through comparing the simulation results with the experimental data of a conventional packed-bed dehumidifier, it is found that the liquid desiccant consumption of the conventional packed-bed dehumidifier is much greater than that under ideal conditions.In the proposed system, the dehumidification process occurs on the surfaces of the micron liquid desiccant droplets produced with the irradiation of ultrasound, so there is a greater contact area created with the same quantity of the liquid desiccant;moreover, the power consumption is lower because there are no nozzles and no solution pump.It can be seen that this new system is closer to ideal conditions when compared with the conventional liquid desiccant dehumidification system.
