【摘要】 地板辐射采暖是一种舒适，节能的新型采暖方式。本文分析了该采暖方式节能的原因，指出人体得到地板辐射热量和温度气流分布的特性是节能的主要原因。本文根据不同的埋管方式的特点，建立了两种不同的数学模型，使用有限差分法数值模拟了地板中的温度场，并与实验结果进行了对比，取得了满意的效果，为设计时控制地板表面温度提供了方法。提出了单蛇型系统的对数平均温差法设计方法，并用数值模拟法和实验法进行了验证。对双回型系统通过数值模拟法得到了不同工况下的有效散热量。最后，开发了供地板采暖设计使用软件。更多还原

【Abstract】 Radiant floor heating is a newly-developed type of heating technology which is comfortable and energy-saving. In this paper, it is discussed that the type of heating technology is energy-saving, the radiant heat which people received from the floor and the characteristics of temperature and carrent distribution are the most important factor. we make two types of mathematical models ,and take the finite difference method for the mathematical simulation of floor simulate the temperature distribution. The result is satisfying through comparing with experimental result, and the method of controlling the floor surface temperature is provided. We expound the logarithm-average temperature design method to the single “S” pattern heating system, and verify it though experiment. At last, a software for design is presented.更多还原
