摘要
建立了吸附式太阳能制冷装置的吸附床热力计算模型。这一模型综合考虑了吸附床内温度、压力及脱附量等因素的相互影响,更全面地反映了吸附床内的传热、传质情况。依据初始条件、边界条件及热力计算模型,给出了数值计算的内点、边界点差分方程,构造了求解方程组。根据太阳辐射强度情况,进行了数值计算,计算结果与实际相吻合。这为进一步分析吸附床内的动态特性,优化系统设计提供了依据。
Thermodynamic calculating model of adsorption bed in the adsorption solar refrigeration equipment was established. The interaction among temperature, pressure, and mass was considered in this model, and the heat and mass transfer in the solar adsorption refrigeration system was described. According to the initial condition, boundary condition and thermodynamic calculating model, the finite difference equation (FDE) of the internal nodes and the boundary nodes was presented, and the solvable equations were established. Based on the change of solar irradiance, the equations were solved by numerical method, and the results were consistent with facts. It offers the basis for further analysis of dynamic characteristic in adsorption bed.
