Absorption factor method for calculating radiant heat transfer among inner surfaces of room enclosure

The net radiant heat transfer can be obtained more accurately by introducing the effective radiation into the traditional calculation method of radiant heat transfer. However, the equation solving is relatively complicated. The simplified calculation for actual engineering purpose tends to resulting in larger error. The absorption factor is derived from the angle factor, and absorption factor method is more suitable for calculating the radiant heat transfer, in which both the direct heat radiation and the reflection influence of other surfaces are involved.
