何种低温辐射供暖加热管道布置方式既能满足规范的舒适性要求,又能节约基建投资和运行费用?本文根据加热管的不同布置形式建立了理论模型,模拟地板辐射供暖中的室内地板表面温度和均匀性。通过与实测结果比较,表明加热管间距为300 mm时出现局部地区温度过热现象,超出《地面辐射供暖技术规程》(JGJ 142-2004)的要求,而400 mm管间距布置方式可满足供暖地板温度和均匀性的要求,同时有利于节约投资费用。综合考虑,推荐采用400 mm加热管间距布置方式。
What kind of low-temperature radiant heating heating pipe layout can meet the norms of comfort requirements, but also to save capital investment and operating costs? This article according to the heating pipe layout of different models to establish a theoretical model to simulate the radiant floor heating indoor floor surface temperature And uniformity. Compared with the measured results, it shows that overheating of the local area occurs when the heating pipe spacing is 300 mm, which is beyond the requirements of Technical Specification for Radiant Floor Heating (JGJ 142-2004), and the arrangement of 400 mm pipe spacing can meet the requirements of heating floor temperature And uniformity requirements, while helping to save investment costs. Taken together, it is recommended to use 400 mm heating pipe spacing arrangement.
