摘　　要：由于寒冷地区气候条件复杂,温度变化剧烈,需要合理控制建筑散热以降低建筑能耗,防止能源过度消耗。因此,提出了寒冷地区绿色节能建筑散热过程的仿真研究。运用Z传递函数计算建筑墙壁传热,获得屋顶或墙壁等热传导的热量,根据建筑的热学性能和特殊边界条件,算出周期实际扰量。建立多层结构建筑散热的非定态热湿耦合传输模型,分析室内外空气的水蒸气交换量,并结合生命周期成本分析法获得节约能耗成本,实现绿色节能建筑散热过程的模拟。实验结果表明,所提方法的建筑散热控制好,建筑节能率高,且有效减少能源消耗的同时保持室内温度稳定。Due to the complex climate conditions and drastic temperature fluctuation in cold regions,it is necessary to reasonably control the building's heat dissipation,thus reducing energy consumption.Therefore,a simulation study on the heat dissipation process of green energy-saving buildings in cold regions was proposed.Firstly,the Z transfer function was used to calculate the heat transfer of building walls,thus obtaining the heat transmitted by the roof or walls.Based on the thermal performance and special boundary conditions of the building,the actual periodic disturbance was calculated.Moreover,a non-stationary coupled heat and moisture transfer model for multi-story buildings was built,and then the vapor exchange rate of indoor and outdoor air was analyzed.Finally,the life cycle cost analysis method was used to obtain energy-saving costs,thus achieving the simulation of the heat dissipation process.Experimental results prove that the proposed method can control the building heat dissipation very well,with high energy efficiency.Meanwhile,it effectively reduces energy consumption while maintaining indoor temperature stability.
