地面的吸热性能是影响采暖建筑地面热工质量的主要依据。我国首次制订的《民用建筑热工设计规程》在有关采暖建筑地面热工性能的规定中指出,地面热工性能的等级按其吸热指数来划分,并规定了吸热指数的计算式和给出了计算方法。本文通过以吸热指数值来划分采暖建筑地面热工性能等级及其计算式进行推导与分析,供建筑热工设计参考。
The heat absorption performance of the ground is the main basis for affecting the thermal quality of heating floors. The Regulations for Design of Thermal Engineering for Civil Buildings formulated for the first time in China pointed out in the regulations on the ground thermal performance of heating buildings that the level of ground thermal performance is divided according to its endothermic index, and the calculation formula of endothermic index is given and given. A calculation method was used. This paper deduces and analyzes the thermal performance level of the floor of a heating building based on the value of endothermic index and its calculation formula, and provides a reference for the thermal engineering design of the building.
