研究了从通过建筑构件的传导到辐射交换和对流到区域内空气的内表面热平衡的一般公式。展示了许多辐射交换模型的发展；这些模型的范围从使用均匀光能传递网络和精确视图因子的精确解到平均辐射温度（MRT）和面积加权视图因子。对于具有不同长宽比的简单区域，这些辐射交换模型直接相互比较。然后比较辐射交换模型，以确定其对冷负荷的影响。最后，研究了影响内表面热平衡的其他参数，以确定它们对冷负荷的敏感性。单位:双关键词:1997年，计算，室内，表面，热平衡，冷负荷，热流，比较，算法，平均辐射温度，灵敏度，建筑引文:研讨会，ASHRAE交易，卷。 103第二部分，波士顿1997

Investigates the general formulation of the inside surface heat balance from the conduction through the building elements to the radiant exchange and convection to the air in the zone. Development of many radiant exchange models is shown; these models range from the exact solutions using uniform radiosity networks and exact view factors to mean radiant temperature (MRT) and area-weighted view factors. These radiant exchange models are directly compared to each other for a simple zone with varying aspect ratios. The radiant exchange models are then compared to determine their effect on the cooling load. Finally, other parameters that affect the inside surface heat balance are investigated to determine their sensitivity to the cooling load.Units: DualKEYWORDS: year 1997, Calculating, indoor, surfaces, heat balance, cooling load, heat flow, comparing, algorithms, mean radiant temperature, sensitivity, buildings
