新型采暖方式地暖系统热负荷的计算问题.rar

地面辐射供暖是一种高效、节能、舒适的新型采暖方式。随着人们生活水平和对采暖要求的提高，这几年地面辐射供暖系统得到了突飞猛进的发展，对地暖系统的设计也有了更高的要求。本文将从建筑物能耗，地面散热量，地热电缆的功率这三方面同广大读者一起探讨地暖系统设计过程中的热负荷计算。
地暖系统的功能就在于弥补建筑物热量损失，维持房间温度，提供舒适、温暖的环境。要使地暖系统实现这一功能，就必须准确了解建筑物的热量损失。建筑物热量损失即建筑耗热量是指建筑物围护结构的传热量和空气渗透热损失。据此定义建筑物耗热量按如下式1计算：
 Q=qH.T+qINF-qI.H式1
Q-建筑物单位面积耗热量。W/㎡
qH.T-单位建筑面积通过围护结构的耗热量。W/㎡

Radiant heating is an efficient, energy saving, comfortable new heating method. As people's living standards and increased demands on the heating, floor heating systems in recent years has been rapid development, the design of floor heating systems also have higher requirements. This article from the building energy consumption, floor heat, geothermal power cable three areas to explore with readers in the process of heating system design heat load calculation.
Function of the system to warm up on the building heat loss is to maintain the room temperature, providing a comfortable, warm environment. For floor heating system to achieve this function, it must be accurate understanding of the building heat loss. Building heat loss means heat loss is building the structure of the building envelope heat transfer and air infiltration heat loss. Accordingly, the definition of building heat loss calculated by the following Equation 1:
 Q = qH.T + qINF-qI.H type 1
Q-building heat loss per unit area. W / m
qH.T-unit building area of heat loss through the envelope structure. W / m
