摘　　要：以典型的夏热冬冷地区气候条件为例,建立焓法数学模型计算相变传热过程,并通过实验证明数学模型的可行性。用数学模型计算相变石膏板放置于建筑外墙对室内温度的影响,对比普通房间进行分析。结果表明,外墙使用相变石膏板的房间温度波动小于普通房间,结合经济型考虑,当相变石膏板相变温度为28℃、相变潜热为80 kJ/kg时,房间的舒适性最佳。The typical hot summer and cold winter region climate conditions as an example, the heat transfer process was calculated using enthalpy model, and the feasibility of the mathematical model was proved through the verification experiment. The influence on the indoor temperature of phase change plasterboard that placed in the building external wall was calculated by the mathematical equation, and was compared with common room. The re suhs shows that the room that its external use phase change plasterboard has less temperature fluctuation than ordi nary room. Combining with economical consideration, when the phase change temperature of the phase plasterboard is 28 ℃, and phase change latent heat is 80 kJ/kg, the room is of the best comfort.
