本文通过对落地式火炕模型已有研究内容进行分析和整理,建立了火炕内部传热的基本通用数学模型,该模型计算的结果,炕面温度非均一,更符合实际火炕特点。作者首先确定了具体的火炕的物理结构模型,之后建立了的火炕传热数学模型,并通过已有的实验数据,对模型进行了验证,证明该火炕热工性能模型的可用性。 Based on the existing research contents of the floor-mounted kang model, this paper established the basic general mathematical model of heat transfer inside the kang. The results of the model show that the kang surface temperature is not uniform and more in line with the actual kang characteristics. The author first determines the physical structure model of concrete kang, and then establishes the mathematic model of heat kang, and verifies the model with the existing experimental data to prove the availability of the kong thermal performance model.
