传统的辐射换热计算中引入的有效辐射可以相对准确计算出净辐射换热量,但在求解方程组时较复杂。实际工程计算中作相应简化,但误差较大。吸收系数是由角系数导出的一个相关因子,采用吸收系数法计算辐射换热,不仅反映了表面之间的直接辐射,同时综合考虑了其他各表面的反射因素对辐射换热的影响,是较适合计算房间各围护结构间辐射换热的一种方法。 The traditional radiative heat transfer calculation of the effective radiation can be relatively accurate calculation of the net radiation heat transfer, but more complex in solving equations. The actual engineering calculations for the corresponding simplified, but larger errors. The absorption coefficient is a correlation factor derived from the angle coefficient. The absorption coefficient method is used to calculate the radiation heat transfer, which not only reflects the direct radiation between the surfaces but also considers the influence of other surface reflection factors on radiation heat transfer. A method suitable for calculating radiation heat transfer between enclosing structures in a room.
