摘 要

针对该新型吸附再生一体式除湿机样机，搭建实验台测量了其性能参数，包括该除湿机的能耗指标（待机、吸附和再生三个过程）、除湿机的极限除湿量、吸附器吸附和再生过程的温升指标、稳定流动条件下除湿机的阻力特性和除湿机内风机的流量特性。并根据除湿机的阻力特性和风机的流量特性测量得出除湿机的工作状态点，通过查阅资料得出文物最佳储存温湿度范围，从而计算得出除湿机吸附器的最佳再生周期。

研究结果表明，该除湿机的性能如下：（1）除湿机的能耗较低。在待机、吸附、再生三个过程中的平均功率分别为1.74W、6.46W、55.80W，功率峰值分别为1.86W、6.75W、394.57W。（2）除湿机的极限除湿量约为32.67g，且受除湿环境温湿度的影响较小。（3）除湿机吸附过程温升很小，约为0.2℃。（4）除湿机再生过程中温升很大，最高温度为104.87℃，且对另一吸附器影响较大，会造成24℃的温升，应对PTC加热器温度进行调整，并对除湿机内部结构进行改进。（5）除湿机内部管路阻力较小。当通入除湿机内气流的流量为4.6L/min时，由于管路产生的压损仅有200.9Pa。（6）除湿机吸附器最佳再生周期为73.5h，满足使用需求。

Abstract：Solid adsorption desiccant technology has a unique advantage on dehumidification of micro-environment requiring high standard on humidity’s control such as display case of cultural relics and filing cabinets. Nowadays there is a neotype adsorption-regeneration integrated solid dehumidifier. With an internal self-regulating PTC heater, this dehumidifier can carry out regeneration process by passing through air in normal circumstance. Comparing with traditional solid dehumidifier like rotary dehumidifier, it has the merits of regenerating conveniently and operating in fewer components. This thesis gives related experimental researches on prototype’s working performance of this neotype adsorption-regeneration integrated solid dehumidifier.

Laboratory bench is set up to test performance parameters of this dehumidifier, including the energy-consumption index(during the process of standby, adsorption and regeneration), the maximum dehumidification capacity, the temperature-rising index in adsorption and regeneration process of absorber, the resistance characteristics under the condition of steady air flowing and the flow characteristic of internal fan. Furthermore, working state point of dehumidifier can be computed according to the resistance characteristics and the flow characteristic of fan, and finally, by means of consulting data to obtain the optimum temperature and humidity range of preserving cultural relics, the best regeneration cycle of dehumidifier can be calculated.

Research results show the working performance of the dehumidifier as follows: (1) The energy consumption of dehumidifier is low. The average power values in three processes of standby, adsorption and regeneration are 1.74W, 6.46W, 55.80W, and the peak power values are 1.86W, 6.75W, 394.57W. (2) The maximum dehumidification capacity is 32.67g, which is barely affected by moisture environment temperature and humidity. (3) The temperature rising in adsorption process is very little, only about 0.2℃. (4)The temperature rising in regeneration process is very large, the highest temperature is 104.87 ℃. And the temperature of the another dehumidifier will be influenced greatly to rise to 24 ℃. Therefore, the temperature of PTC heater should be adjusted and the internal structure of dehumidifier should be improved. (5) The dehumidifier’s internal pipeline resistance is small. When the flowing of air stream is 4.6L/min, the pressure loss caused by the pipeline is only 200.9Pa. (6) The best regeneration cycle of dehumidifier is 73.5 hours which meets the using demand.
