摘　　要：提出一种便于工程设计应用的太阳能采暖房间热负荷动态计算方法。通过Z传递函数分析墙体动态传热过程,根据编程计算所得的墙体传热量逐时结果,获得太阳能采暖房间热负荷系数。通过对不同朝向墙体以及不同墙体结构的计算后发现:墙体热容量越大,热负荷系数的日变化幅度越小;同一结构,但不同朝向墙体的热负荷系数存在较大差别。This paper puts forward a heating load dynamic calculation method for solar heating room, which is easy to engineering design application.By Z transfer function ,this paper analyzes wall dynamic heat transfer process,and according to the hourly result of wall heat transmission, which is obtained by programming calculation,gets the heating load coefficient of solar energy heating room. By the calculation of different orientation wall and different wall structure,finds：the lager the wall heating capacity,the smaller the daily changing amplitude of heating load coefficient; the same structure, but with different orientation wall, the heating load coefficient has obvious difference.
