夏热冬冷地区辐射地暖间歇供暖实验研究 ☆ 浙江大学建筑工程学院 王登辉 赵康 葛坚 摘 要：为研究夏热冬冷地区辐射地暖技术的适用性以及不同形式辐射地暖的运行特点， 包括不同形式地暖房间的热环境特点、围护结构热响应及系统节能情况，搭建了具有三种不同 形式辐射地暖（干式、湿式与毛细管型辐射地暖）的实验平台，并对这三种形式的辐射地暖进 行了连续与间歇供暖的测试。实验结果表明：湿式和毛细管型辐射地暖因设有混凝土填充层， 蓄热能力较强；干式系统蓄热能力较差，但升温与降温速度最快，适合间歇供暖的使用场所； 三种形式地暖系统在垂直方向上温度都分布均匀，具有较好的舒适性。 关键词：夏热冬冷地区 辐射地暖 间歇运行 Experimental Study on Intermittent Heating Performance of Lightweight, Heavy and Capillary Radiant Floor Heating System in Hot Summer and Cold Winter Area College of Civil Engineering and Architecture, Zhejiang University Abstract: In order to study the applicability of radiation ground heating technology in hot summer and cold winter area and the selection of different forms of radiant floor heating system, to understand the characteristics of indoor thermal environment, the thermal response of enclosure structure and the energy-saving of heating system, an experimental platform with three different forms of radiant floor heating system (lightweight, heavy and capillary type) was built, and the continuous and intermittent heating testing plan were carried out for these three forms of radiation ground heating system. The experimental results show that: the heat storage capacity of heavy and capillary radiation ground heating system is strong because of concrete filling layer, while the heat storage capacity of lightweight radiation ground heating system is poor, but the speed of heating and cooling is the fastest, so it is suitable for the use of intermittent heating. The temperature distribution in the vertical direction of the three types of ground heating system is uniform leading to a comfort indoor environment. Keywords: hot summer and cold winter area, radiation ground heating system, intermittent heating 1.前言 随着居民生活水平的提高，对于冬季采暖的需求也愈来愈为强烈。在夏热冬冷地区，也有 许多的居民开始选择地暖作为冬季取暖的主要方式，目前地板辐射供暖系统按照其构造可分 ☆ 王登辉，男，1993 年
