以干式地板辐射供暖系统为研究对象,通过实验研究的方法,测量系统从开启到关闭后5h的室内温度、地板表面温度、围护结构表面温度等参数,分析系统热工特性和热舒适性。研究结果表明:系统稳定运行时,室内空气温度在水平和竖直方向分布均匀,热稳定性好,辐射换热量占总换热量的60%,运行3h可满足热舒适性要求;同时,也存在相对于湿式地板供暖,系统蓄热性较差、地板表面温度分布均匀性略差问题。
Taking the dry floor radiant heating system as the research object, the parameters of the indoor temperature, the surface temperature of the floor and the surface temperature of the enclosure structure were measured by means of experimental study after 5 hours from opening to closing to analyze the thermal and thermal comfort of the system . The results show that when the system is stable, indoor air temperature is evenly distributed in the horizontal and vertical directions with good thermal stability, radiation heat transfer accounts for 60% of the total heat exchange, and operation for 3h can meet the thermal comfort requirements. At the same time, Relative to the wet floor heating, there is also a poor system of heat storage, the floor surface temperature distribution slightly worse problem.
