摘    要:在低温热水地板辐射供暖系统的计算中,原用的平面肋片模型假设地板的温度场是一维的。本文在原有模型基础上按二维温度场对肋片效率和肋基温度进行了修正,提出了基于改进型平面肋片模型的地板散热量计算方法,提高其计算的准确改正性。

关 键 词:地板辐射供暖系统  平面肋片  肋片效率  肋基温度

Abstract:Original plane fin model of calculation for heat dissipating capacity in low-temperature hot water floor radiation heating system was hypothesized one-dimensional temperature field in floor.On base of this,fin efficiency and fin bed temperature is revised with two-dimensional temperature field.An improved plane fin model calculation for heat dissipating capacity in floor radiation heating system is presented.This improved model makes calculation more accurate.
Keywords:floor radiation heating system  plane fin  fin efficiency  fin bed temperature
