新型采暖方式地暖系統熱負荷的計算問題.rar

地面輻射供暖是一種高效、節能、舒適的新型采暖方式。隨著人們生活水平和對采暖要求的提高，這幾年地面輻射供暖系統得到了突飛猛進的發展，對地暖系統的設計也有了更高的要求。本文將從建筑物能耗，地面散熱量，地熱電纜的功率這三方面同廣大讀者一起探討地暖系統設計過程中的熱負荷計算。
地暖系統的功能就在于彌補建筑物熱量損失，維持房間溫度，提供舒適、溫暖的環境。要使地暖系統實現這一功能，就必須準確了解建筑物的熱量損失。建筑物熱量損失即建筑耗熱量是指建筑物圍護結構的傳熱量和空氣滲透熱損失。據此定義建筑物耗熱量按如下式1計算：
 Q=qH.T+qINF-qI.H式1
Q-建筑物單位面積耗熱量。W/㎡
qH.T-單位建筑面積通過圍護結構的耗熱量。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
