采用非稳态热重法测定了吸附制冷工质对13X-H2O的有效扩散系数。测量范围是：温度50～250℃，压力0.6～3．5kPa。实验数据表明，压力和吸附量在测量范围内对有效扩散系数的影响很小，可近似折算于有效扩散系数与温度的依赖关系——Arrhenius方程中。水分子的表面扩散是颗粒内扩散的主要控制因素。

The effective diffusivity of adsorption refrigeration working pair 13X-H2O was determined by TG in unsteady diffusition.The data range is from 50℃ to 250℃ in temperature and from 0.6kPa to 3.5kPa in pressure.The experimental data showed that the influences of pressure and concentration on the effective diffusivity are very small and can be expressed in the Arrhenius equation.The surface diffusion of water is the main control factor in the pellet diffusion.
