摘要
引入当量发射率表示不同形状、不同温度下室内热源的表面辐射特性，详细考察分析了具有中、低表面温度的散热设备、灯具和人体的辐射散热量及其比例，给出了不同温度下设备、人体的辐射热比例及不同功率下灯具的辐射热比例。
Examines and analyses radiant heat gain from heat emitting equipment with medium or low surface temperature, lighting fixture and occupants in detail, by introducing an equivalent emissivity to characterise the surface of a radiant heat source with different shapes and different temperature in a conditioned space. Examines major factors affecting it. And presents percentages of radiant heat under different temperature and/or electric power conditions.
