摘　　要：农村屋顶的热损失占比达到整个居住建筑热损失的五分之一以上,故而在严寒期时候,对赤峰地区两个不同农牧区的典型住宅屋顶进行了实际的测量。调研了两个地区典型农宅,发现农区多为两坡屋顶、牧区多为四坡屋顶,使用温度和热流自记仪对典型户进行实际测量,基于传热学理论和火积耗散分析各自的热工性能。在瞬时波动特性和算数平均值上,温度和热流均呈现正相关性,两户农宅火积耗散和传热系数的比值相近,传热系数与规范值比仍然较大。Rural roof heat loss is more than a fifth of the total residential building heat loss.Two typical roofs in Chifeng area were measured during the cold period.The typical farm houses in two areas were investigated.It is found that the agricultural area has two sloping roofs and the pastoral area has four sloping roofs.The temperature recorder and heat flow recorder were used for the actual measurement of the typical household.The thermal performance is analyzed based on heat transfer knowledge and entranspy theory.The instantaneous value and average value of temperature and heat flux are positively correlated.The ratio of entranspy dissipation and heat transfer coefficient was close.The heat transfer coefficient is larger than the standard value.
