چکیده
Abstract Indoor air humidity evaluation plays an of great importance role on the thermal comfort and building energy consumption. The utilization hygroscopic materials as acts indoor by regulating its fluctuations, then reduces a certain fraction consumption conditioning systems. Based Fick’s law, physical process inside these requires determinations hygrothermal properties, which signify extensive reiterative experiments. While in many simulation toolboxes, moisture buffering behavior has been evaluated either simple approximations or complicated heat mass model. In this case, we developed mathematical model about transport with acceptable solution time accuracy terms buffer value (MBV) theory. Considering that MBV originally represents capacity those materials, did some deduction MBVs under different boundary conditions. Then definition time-average used, all required parameters was obtained from practical test. By comparing new (MBM) HAMT model, results indicated MBM could provide reasonably accurate prediction for variation.
