地板采暖用平面盘管传热与流动特性的实验研究

An Experimental Investigation of the Transfer Heat and Hydraulic Character Plane Curved Tubes

通过对地板采暖常用的几种平面盘管在一定流量范围、不同低温供水温度下传热和流动性能的实验研究,得出了各盘管换热和流动阻力随雷诺数、盘管几何条件等的变化关系曲线及部分经验公式,为平面盘管在地板供暖等工程中的应用提供理论依据。

This paper studies the fransfer heat and hydraulic character of several plane curved tube systems with low supply water temperature in arange of flow by experiment, and gives the telationship befween the transfer heat coefficient and resistance cofficient with Renolds number and geometry of fube This conclusion is useful in the engineering applicafion of floor heating.
