流径直接铺设在土壤上的非保温地板的热流由两部分组成,即: 1.边缘损失。它与地板外周边长和室内外温差成正比。 2.地面损失。它取决于室内空气的温度和地板下土壤的温度之差,并与地面的形状和面积大小有关。上述两部分中,边缘损失是比较重要的,因为非保温地板单位面积上的热损失随着面积的增加而减少。此外,由于土壤的导热 The heat flow of the non-insulated floor where the flow path is directly laid on the soil consists of two parts, namely: 1. Edge loss. It is proportional to the length of the outer perimeter of the floor and the temperature difference between indoor and outdoor. 2. Ground loss. It depends on the difference between the temperature of the indoor air and the temperature of the soil under the floor, and is related to the shape and area of ​​the ground. In the above two parts, the edge loss is more important because the heat loss per unit area of ​​the non-insulated floor decreases as the area increases. In addition, due to the thermal conductivity of the soil
