摘要
装配式地暖作为建筑采暖系统的一种重要末端形式,其对采暖系统能效提升的贡献取决于装配式地暖的供热特性和节能性.基于CFD方法研究了装配式地暖与传统地暖的传热过程特点,对比分析了两者在地板表面温度上升过程和地板内部温度分布的差异.研究结果表明,装配式地暖可以更快地提升地板表面温度,且稳定温度更高.同时,装配式地暖漏热损失低于1％.此外,通过对结合室外气象参数的单面外墙的住宅的仿真模拟发现,与传统地暖能耗相比,装配式地暖的节能率不低于70％.
Abstract
As an important end form of building heating system,the contribution of assembled floor heating to the energy efficiency improvement of heating system depends on the heating characteristics and energy saving of assembled floor heating.Based on the CFD method,the characteristics of heat transfer process of assembled floor heating and traditional underfloor heating are investigated,and the differences between the two in the process of temperature rise on the surface of the floor and the temperature distribution inside the floor are compared and analysed.The results show that the assembled floor heating can increase the surface temperature of the floor faster,and the stable temperature is higher.At the same time,the heat loss of the assembled floor heating leakage is less than 1 percent.In addition,a simulation of a house with a single facade incorporating outdoor meteorological parameters found that the energy saving rate of assembled floor heating was no less than 70 per cent compared with the energy consumption of conventional floor heating.
